O'Leary, William J.
by David Murphy

O'Leary, William J. (1869–1939), Jesuit priest and scientist, was born 19 March 1869 in Dublin, son of Dr William H. O'Leary (qv), MP for Drogheda 1874–80, surgeon, and professor of anatomy at the Royal College of Surgeons in Ireland, and Rosina O'Leary (née Rogers). Educated at St Stanislaus College, Tullabeg, King's Co. (Offaly), and Clongowes Wood College, Co. Kildare, he entered the Society of Jesus in 1886, completing his noviciate at Dromore, Co. Down. He studied philosophy and astronomy at Louvain and theology in Dublin, and then taught science at Clongowes. In 1908 he travelled to Strasbourg and studied seismology under Prof. Meinka, and on his return to Ireland he set up a meteorological and seismological observatory at Mungret College, Co. Limerick, remaining as its director until 1915. At the request of a joint committee of the British Association and the Royal Meteorological Society, he carried out a series of upper-air investigations using sounding balloons (1911–14). This was the most westerly series of observations taken in Europe, and the results of O'Leary's research were published in the journals of both societies. By 1911 he had also completed a new seismograph, and this instrument was later praised by the astrophysicist and cosmologist, (Edward) Arthur Milne (1896–1950).

In 1915 he moved to the Jesuit community at Rathfarnham Castle, Dublin, and founded a seismological observatory there. He constructed his own seismograph, which had a moving mass of one-and-a-half tons. This instrument was still giving excellent service in the 1940s. He had also become aware of the need for extremely accurate timing in seismology and, turning his attention to chronometry, developed a free-pendulum clock which he patented in 1918.

In 1929 he went to Australia, where he became director of the observatory at Riverview College, New South Wales. In conjunction with the Lembang observatory in Java, he began a programme of photographic research on variable stars. He discovered several new variable stars, and the results of his research were published in the journals of the Riverview and Lembang observatories and also in the Astronomische Nachrichten. An accomplished and humorous speaker, he was extremely popular as a lecturer at scientific and public meetings. He supervised (1933–4) the construction of one of his free-pendulum clocks for Georgetown University. The clock was built by E. Esdaile & Sons in Sydney and shipped to Washington DC in August 1934, and O'Leary visited Georgetown in 1938. He was a leading member of several scientific societies, including the RIA (elected 1919), the Royal Society of New South Wales, the Société Astronomique de France, and the Seismological Society of America. He was also a member of the Australian National Committee on Astronomy and was elected (January 1938) a fellow of the Royal Astronomical Society.

He collapsed and died of a heart attack while playing golf (16 April 1939), and was buried at the Gore Hill cemetery, Sydney. There is a collection of his papers in the Irish Jesuit archives in Dublin, including seismological journals that he kept while at Rathfarnham. In February 1959 Georgetown University donated to the Smithsonian Institution its O'Leary free-pendulum clock and the collection of letters relating to its construction.

JESUITICA: Earth-shakers
In the days when Rathfarnham Castle was still a residence for Jesuit university students, there was a seismograph (pictured here) housed in a small building off the drive. It was the creation of Fr William O’Leary, a Jesuit scientist with an avid interest in pendulums, who had already constructed a seismograph in Mungret in 1909. He had to keep air currents and spiders at bay, since their delicate vibrations could simulate the effect of major earthquakes on the sensitive instrument. He had dreadful luck in September 1923 when his seismograph was temporarily out of order during a catastrophic (over 100,000 dead) earthquake in Japan. But his pioneering work introduced generations of Jesuit students to the rigorous measurement and technical skill required in scientific research.

William O'Leary was educated at Tullabeg and Clongowes; his father was a surgeon and a Member of Parliament. While at Tullabeg he developed an interest in science. He entered the Society at Dromore, 30 October 1886, did his juniorate at Tullabeg, 1888-90, studied philosophy at Louvain, 1890-93, where he did much experimental work with the inverted pendulum. He later taught mathematics and physics at Clongowes, 1893-99, studied theology at Milltown Park, 1899-03, and finished his studies with tertianship at Mold, Wales, 1904-05. In 1900 he published a textbook on mechanics.
In an obituary notice in the “Monthly Notices of the Royal Astronomical Society, Vol. 100, No. 4,” 1940, it said that O'Leary's “mind ran on original lines. He was never content with stereotyped textbook solutions, he had to work out each problem for himself from first principles. In this way he was able to study many questions from a fresh angle and to develop original lines of research various branches of science. Combined with this was a highly developed inventive talent and the ability to design new instruments and the skill to construct them”.
After studies, O'Leary taught physics, chemistry and mathematics, and was assistant prefect of studies at Mungret, 1905-15, as well as director of the seismological and meteorological observatory At the request of a Joint Committee of the British Association and the Royal Meteorological Society he carried out a series of upper-air investigations by means of sounding balloons. These were the farthest west observations had been made in Europe at the time.
One problem in seismometry was to obtain an instrument with a fairly long period and consequent high sensitivity O'Leary provided a satisfactory solution by constructing a two
component horizontal seismometer with trifilar suspension. One of these instruments was completed in Mungret in 1911. Later, he lectured in mathematics to the juniors at Rathfarnham, 1915-18, and started seismological observatory His “O’Leary Seismograph” was at that time the first and only one in the world. He also worked with Professor John Milne at the Shide Observatory in the Isle of Wight, and from whom he acquired the Milne-Shaw seismograph for his own seismography station at Rathfarnham. With these two seismographs, O'Leary was able to supply earthquake information to the whole country. The need for accurate timing in seismology turned O'Leary's attention to chronometry He saw that the secret of precision timing was to be sought in a free pendulum. He was one of true pioneers in the development of the free-pendulum clock in 1918.
O’Leary was minister, procurator and teacher at Belvedere, 1918-19, and then lectured mathematics and physics to the philosophers at Milltown Park, 1919-29.
He was was appointed to the Riverview observatory in July 1929. Besides introducing various improvements in the seismological department, he initiated a programme of photographic research on variable stars in collaboration with the Boscha Observatory, Lembang. He also invented and built a blink comparator, which proved successful in searching for new variable stars. He discovered many new variable stars and published several papers on variables in “Publications” of the Riverview and Ban Len Observatories and in the “Astronomisrlne Nachrichten”. Other inventions included a recording anemometer and a petrol gas plant.
Scientists and the general public appreciated O’Leary's lectures on astronomy and seismology His light and humorous touch combined with his clarity of exposition to render topics intelligible and interesting. Together with his scientific work, he found time to do good work as a priest. Many found him a wise counselor, and a humble and lovable priest and colleague. He was a little man, happy, charming, and quite unassuming in spite of his deep knowledge and high reputation.
He remained at Riverview until his death in 1939, directing the observatory until 1937 when Daniel O'Connell became director. The end of his life occurred when he collapsed and died on the golf course just after driving off. The suddenness of his death was a shock to the community, but he had had a heart condition for some time. This did not prevent him from planning fresh research and for new instruments. The day before he died he discovered a number of new variable stars with his newly completed comparator, and that night worked at the telescope taking star photographs. O'Leary was a member of the Royal Irish Academy, the Royal Society of NSW, the Société Astronomique de France, the Seismological Society of America, Past President of the NSW Branch of the British Astronomical Association, and a fellow of the Australian National Committee on Astronomy.

Note from Daniel O’Connell Entry
At this time he came under the influence of William O'Leary, the Irish Jesuit astronomer and seismologist, who at that time was director of Rathfarnham Castle Observatory in Dublin. While at the Riverview Observatory, working under William O'Leary.........

Note from Edward Pigot Entry
His extremely high standards of scientific accuracy and integrity made it difficult for him to find an assistant he could work with, or who could work with him. George Downey, Robert McCarthy, and Wilfred Ryan, all failed to satisfy. However, when he met the young scholastic Daniel O'Connell he found a man after his own heart. When he found death approaching he was afraid, not of death, but because O’Connell was still only a theologian and not ready to take over the observatory. Happily, the Irish province was willing to release his other great friend, William O'Leary to fill the gap.

Rathfarnham :
Seismological Station : A change was made in the method of recording un the O'Leary seismograph. The records are now made on smoked paper by a stylus which gives a very clear, delicate trace. This method replaces the former ink inscriptions and is calculated to give much greater sensitivity, The improvement was carried out at the suggestion of Father O'Leary, Director of Riverview College Observatory, who sent all the necessary detail of construction. On January 7th the first big earthquake of the year was recorded and the success of the new method was assured.

Father O'Leary died in Australia, Sunday, April 16th, 1939
Father O'Leary was born in Dublin, 1869. His father William O'Leary, well known for his medical ability, and for time a Home Rule M.P. in the party of Isaac Butt. Father O'Leary was educated at Tullabeg and Clongowes. He was best known as a teacher of physics and astronomy in the Colleges and Scholasticates, and for his work on seismology. His scientific work tends to make us forget his other gifts as a preacher and Retreat-giver, in which he was remarkably successful. As student at Louvain he developed an interest in pendulums, which was the basis of his seismological activities. A full account of his work in that department has been given in the “Irish Jesuit Directory” for 1938. A visit to Prof. J, Milne's observatory at Shide, Isle of Wight, was the occasion of his applying his knowledge of pendulums to the construction of his first instrument at Mungret. During the following years he constructed and equipped a really good seismological and meteorological station there, which he left behind him as a monument to his energy and activity when he was transferred
to Rathfarnham. Here, with characteristic perseverance, he continued his work, and set about designing and constructing the instrument now in use at Rathfarnharn, in conjunction with a standard Milne-Shaw seismograph added to the Observatory in 1932. This instrument was not meant to replace the “O'Leary Seismograph”, but to give greater accuracy in the recording of earthquakes. The horizontal pendulum of the latter has a mass of 1 lb. , the O'Leary pendulum has a mass of 1.5 tons. This is the only instrument of its kind in existence, and gives an exceedingly large and clear record.
An essential element in the recording of earthquakes is a very accurate clock, which enables the exact time to be recorded on the chart. Father O'Leary designed such a clock, which includes features of great novelty. In connection with this instrument Father O'Leary paid a visit to the United States. The clock has been described by the director of a well-known observatory as “a piece of first-class and most original work”. It is of interest to put on record that Father O'Leary not only designed both clock and seismograph, but made almost every part of each, and erected them himself. In addition to these instruments he designed a system of supplying petrol-gas for laboratories far from a supply of coal gas. This apparatus had a considerable success, and for some years was on the market, until trade difficulties stopped the sale. In addition to the records of his observations, Father O'Leary wrote a text-book on mechanics.
When Father Pigot died in Australia, in 1929, then a portion of the Irish Province, Father O'Leary was chosen to succeed him as director of the Riverview College Observatory, which included astronomy, seismology and meteorology, where his knowledge and experience enabled him to do much valuable work.
His death came suddenly and unexpectedly, as he had been working in the observatory only the night before. The Australian and home newspapers contained most appreciative notices of his work. An indication of the esteem in which he was held may be gathered from the Press account of his funeral. Archbishop Gilroy presided at the Mass, at which were present Archbishop Duhig and Bishops Coleman, Dwyer and Henscke, together with some 200 priests and many representatives of Catholic schools. The laity included many distinguished scientists and representative men, such as the Attorney-General, etc. Father O'Leary was an F.R.A.S., and past-President of the British Astronomical Association.
Those who knew Father O'Leary will miss him not only as a worker, but still more for his great charm and his many gifts, which made him an excellent community man and endeared him to all by his cheerful companionship and great sense of humour. He was noted for his punctilious observance of all his spiritual duties, and died as he had lived, working for God. RIP
The following came from an Irish priest :
"During the last few weeks I have felt that I would like to write and offer to you and your distinguished Order my sympathy on the death of Father O'Leary. Many, I am sure, have written many others, too, better equipped than I, shall write about him but as a humble priest, I would like to add my humble tribute to the memory of a saintly priest and a learned Jesuit.
When I took up the paper a few weeks ago and read the cabled account of his death, I could read no further. I was truly grieved, for I felt I had lost a great friend, a friend who was, I thought, in perfect health, when I met him only a few months ago. Our friendship began ten years ago on the emigrant ship that was relentlessly taking both of us to Australia. He, fairly advanced in years, I, a young priest just ordained. He, the eminent scientist and inventor, on his way to take up one of the highest and most important positions in Australia, I an obscure priest, to take up duty as a curate in some parish in the Diocese of Sydney. None of us young priests realised that we were travelling with such a distinguished man. There was nothing that led us even to suspect it. He moved among us, spoke freely to us offered us his sympathy for he knew our hearts were full. His heart, too, was full, for he felt then that he would never see again his beloved Ireland. I often thought it was a pity that he should have to leave Ireland at his time of life, for he loved Ireland with a love that was passionate, yet tender. Whenever I visited him at Riverview, that College so beautifully situated on an eminence overlooking Sydney's wondrous harbour, his thoughts ever wandered back to Ireland. Like every exile. as he wrote himself, he hankered for the green hills of holy Ireland. Others shall appraise his work as a scientist and astronomer - to me he was always the humble, sympathetic, priestly friend. With his passing I have lost a great friend, and Australia has most certainly lost an able and scholarly Jesuit, and saintly priest.
I am sure that his soul passed through Ireland on its way to Eternity. May he rest in peace".

◆ James B Stephenson SJ Menologies 1973

Father William O’Leary SJ 1869-1939
The name of Fr William O’Leary will go down in the Province as the founder of the seismograph at Rathfarnham Castle. He was also the inventor an ingenious clock and numerous other scientific devices, as well as author of a textbook on mechanics. But these achievements as a scientific inventor were hardly half the man.

He had a remarkable oratorical ability, and many a priest of the Province will recall his elocution classes … “O Mary, call the cattle home, call the cattle home across the sands of Dee”. He was a preacher and retreat giver of no mean order,

In 1939 he was appointed to the Directorship of the Observatory at Riverview, Australia. His end came suddenly on April 16th 1939, but found him not unprepared, for he was a religious of punctilious observance and scrupulous even to a fault in the matter of poverty.

LEST HE BE FORGOTTEN : FR WILLIAM O’LEARY

Kevin A Laheen

There is a rumour doing the rounds in Rathfarnham at present that the building that once housed the seismograph will shortly be used as a snack-bar and tea room. Just in case there may be some truth in this rumour it would seem opportune to recall the name of Fr William O'Leary, SJ whose pioneer work in recording earthquakes won international acclaim for the seismograph station at Rathfarnham Castle.

Willie O'Leary was born in Dublin on 19 March 1869. The O'Leary family lived in Ranelagh. His father was a distinguished doctor, a Member of Parliament, and a personal friend of Isaac Butt. Willie spent the early years of his schooling in Tullabeg and then moved off to Clongowes when the two colleges were amalgamated in 1886. After his novitiate in Dromore he moved, back to Tullabeg to begin his Juniorate studies. In Tullabeg he manifested a great interest in and aptitude for science. It was during his philosophy years at Louvain that he did some experimental work on the inverted pendulum. This was the beginning of a lifelong work in the study of seismology which won for him an eminence in that science and in meteorology, and also, to a lesser degree, in astronomy.

During his years in Mungret College, 1905-15, his theories about earthquakes began to take practical shape. He built a house of solid stone some distance from the main building and in it he continued his study and experiments. His work during those years is well documented in the MUNGRET ANNUAL. However, it was in Rathfarnham Castle during the years 1915 17 that he built his own seismograph and the clock that recorded the time at which an earthquake took place. The famous “O'Leary Seismograph” was the only one of its kind in the world at that time and widespread interest in it was evident in international science circles.

He was on personal friendly terms with Professor John Milne, whose observatory in Shide, the Isle of Wight, he had visited on more than one occasion. Through this contact he acquired the Milne-Shaw seismograph for the station in Rathfarnham Castle. This instrument was not a substitute for Fr O'Leary's one, but both worked in tandem, recording the same earthquake though by different methods. The O'Leary seismograph recorded the quakes on a sheet of smoked paper on a large revolving drum, while the Milne-Shaw instrument recorded them by photography. It was interesting to watch the white lines being traced on the smoked paper as the drum revolved slowly while every minute the two glass pen nibs gave a tiny kick to the right in order to record the time.

Fr O'Leary's work received widespread notice in scientific publications. He was a Feilow of the Royal College of Science, and also a President of the British Astronomical Association. His reputation was so outstanding that when Fr Edward Pigot, SJ died in Australia in 1929, Fr O'Leary was requested to take his place as Director of the Observatory at Riverview College - “one of the highest and most important positions in Australia”. It was there during his early sixties that his work was highly appreciated and where at the same time he had an opportunity to further his own knowledge of astronomy.

Research and experimental work such as was done by Father O'Leary, is a very lonely occupation, and few people outside the researcher's field will manifest much interest. Fr O'Leary was fortunate in the fact that Fr Thomas V Nolan, SJ who was his Rector in Mungret College, appreciated his work and gave him every encouragement and support. Later Fr Nolan was appointed Provincial and in that office continued his sponsorship of Fr O'Leary's work. Providence was again on Fr Willie's side when they were both assigned to Rathfarnham Castle, Fr Nolan being the Rector and again continued to support him, especially in the erection of the seismograph station. He also encouraged Fr Willie to maintain his friendship with Professor Milne and to visit him at his observatory at Shide. Without this support one might be justified in asking if Fr O'Leary's experiments would ever have bome the fruit they eventually did.

In addition to his eminent place in the international community of scientists he was also a gifted preacher. He was much in demand as a retreat director, and was especially skilled in directing retreats to the clergy. His contemporaries found him a most affable companion who gladly shared his knowledge with anyone who manifested even the slightest interest in it. He died in Australia in 1939 in his seventieth year. Present at his funeral two archbishops, three bishops, over two hundred priests, and representatives from various branches of science. A priest who first met him on the ship en route for Australia, on hearing of his death, wrote, “In his passing I have lost a great friend, and Australia has certainly lost an able and scholarly Jesuit and a saintly priest”.

Should the building, which housed his seismograph station in Rathfarnham, ever become a snack-bar, it would certainly be appropriate to have a plaque or other memorial put up there. This would record the significant contribution to science that was made in that building, and would prevent the name and work of this great Jesuit from being forgotten.

I feel it is appropriate to conclude with a personal memory. One morning, midway through the Second World War, Dick MacCarthy and I were working in the seismograph station. Suddenly I noticed that the glass pens on the great revolving drum began to register a quivering motion. I called Dick and, in a matter of seconds, the pens went off in a swaying motion from left to right. We both realised that we were witnessing the great O'Leary seismograph recording an earthquake. Before the pens settled down, Dick had calculated that the epicentre of the earthquake was in the Pacific Ocean. In those days the house telephone was definitely off limits for all of us except Dick, who was allowed to use it for business connected with the station. He telephoned the Dublin newspapers with the news. An hour or so later we both cycled to the university for the morning lectures. Standing at the gates of the building was a newsboy crying out the greatest piece of misinformation ever heard, “Stop press! Stop press! Earthquake at Rathfarnham Castle!” We both had a laugh, and Dick said, “I bet the Rector will blame the pair of us for that”.

During the days of the war when news of any sort was censored and generous blackouts were imposed on any type of information, we were a real sensation among our fellow students for bearing the first bit of uncensored news to reach Dublin that day. Dick, who remained a close friend of mine all his life, died in Hong Kong a couple of years ago.

Obituary

Father William J O’Leary SJ

Father O’Leary was born in Dublin on March 19th, 1869. His father was Dr W O'Leary, a well-known doctor and a Home Rule MP in Isaac Butt's party. Father O'Leary was educated at Tullabeg (1880), but came to Clongowes at the amalgamation for a few months in the summer of 1886 to prepare for the “Autumn Matric”. He was a master at Clongowes 1893-'98, and again in 1903; after his ordination. Practically his whole life was occupied in the teaching of science and mathematics at Clongowes and Mungret, and in the Scholasticates of Rathfarnham and Milltown Park. During his philosophical studies at Louvain he became interested in pendulums, and did some very interesting experiments with compound pendulums, obtaining some beautiful curve records. This interest seems to have been the occasion of his interest in seismology later on. A visit to the observatory of Prof J Milne FRS., at Shide IOW., was the beginning of his work in that departinent. At Mungret he created a seismological and meteorological station which he fitted up with instruments of his own design. During this time he also made observations on high-altitude conditions by means of balloons. He was transferred to Rathfarnham in 1915, where he still further improved his apparatus, Here he designed and constructed one of the instruments still in use in the present station. This instrument is the only one of its kind in existence and gives a very open record. It is of the inverted pendulum type, and the “bob” weighs 1.5 tons! It was designed, constructed all except the “bob” and erected by Father O'Leary himself, who, in addition to his other gifts, was a skilled mechanic. Later on he was professor of Mathematics, Physics and Astronomy to the Jesuit philosophers at Milltown Park.

On the death of Father Pigot SJ, Director of the seismological and astronomical observatory of Riverview College, Sydney, he was appointed as his successor, and went to Australia in 1929. His previous studies and practical experience had fitted him for this position, and enabled him to do splendid work in his new post. Here, in addition to seismology, his work included such branches of astronomy as observations on solar radiation, and on variable stars. It is to be hoped that a full account of his work in Australia will be given us. As an inventor he also designed a method of supplying laboratories not in possession of coal gas, with petrol gas, both for illumination and heating. He published a text-book on mechanics, but, with the exception of the records of his observation, does not seem to have written anything else. Reference must be especially made to an accurate clock which he designed and constructed on principles first applied by him, which was for use in connection with his seismograph. Such a clock is an essential element in the recording of earthquakes, for it is necessary that a mark be made on the chart very accurately every minute. His clock combined the properties of extreme accuracy with the means of recording the minutes on the chart. Referring to this clock, Father D O'Connell SJ, the present director of the Riverview observatory, says that it is a most excellent and original piece of work. Except in the patent specification, the details have never been published. It is to be hoped that this will be included in an account of his scientific work.

But it would be a mistake to allow the record of his work as a scientist to render us oblivious of his other and far inore important qualities. All who knew Father O'Leary as a friend and companion need no reminder of his wonderful charm and gifts of character which made him popular with all. A great love of his country, and a strong sense of humour were characteristic of him. He has a fine voice, and as a preacher he was no less in demand than as a lecturer and giver of retreats. His friends have lost one who will not easily be replaced.

Himself the most unassuming of men, he was honoured by his scientific brethren, no less than he was loved by his brethren in religion. He was a member of the British Association, and more than once was special preacher at their meetings; he was also a Fellow of the Royal Astronomical Society, and Past President of the NSW branch of the British Astronomical Association.

His death came suddenly. He had been suffering from his heart, but this did not interfere with his work, and he had been working in the observatory only the night before. An indication of the esteem in which he was held in Australia may be gathered from the press account of his funeral. Archbishop Gilroy presided at the Requiem Mass, at which assisted Archbishop Duhig, and Bishops Coleman, Dwyer and Henscke. In addition, there were 200 of the clergy, as well as representatives of the Catholic educational establishments. A large number of distinguished laymen were also present, including the Attorney-General, members of the University and the president of Astronomical Society and Government Astronomer. RIP

The following appreciation is from the pen of one who for many years taught in the same college as Father Willy :

For many years after his ordination, Father O'Leary taught in Mungret, and for a considerable portion of that period acted as Prefect of Studies. A splendid master, be had the gift of imparting knowledge clearly and of getting the boys thoroughly interested in their work. His subjects were Science, Mathematics and Latin. His lessons in Geometry were particularly fascinating - his own consummate skill in the use of instruments and the beautifully accurate figures which graced his blackboard made his pupils quite enthusiastic in their efforts to imitate and emulate him. He made the dry bones of that subject live -no easy task where boys are concerned.

He was highly popular with all the boys, though he never showed any undue leniency. He was strict, but not severe, just and impartial. All these features were prominent in another sphere of school life; Father O'Leary possessed histrionic talent in a high degree. His production, in conjunction with the late Father Willie Doyle, of the “Mikado” inaugurated the revival of theatricals in Clongowes. In Mungret he staged the “Private Secretary”, a very successful performance, one of many similar triumphs.

In the spiritual sphere he did untold good. He was director of the sodalities, a superb preacher, being a first class orator. Only those who lived with him could appreciate to the full the power of his example. He was popular, as we have said, but he used this as a powerful influence for good.

Boys are proverbially prone to hero worship, and this small, though tremendously strong, straightforward, cheerful and great hearted priest won their affection and admiration. They appreciated his great qualities in life, and we trust they will not forget him in death. Requiescat.

Father H V Gill has mentioned above that Father O'Leary had a great love for his country; here is an extract from a letter of Father Willy's to a friend in Ireland, written for the New Year :--

“Dear Ireland, how I wish I could see you again. I am too old to fall in love with strange lands and I love you alone. May God bless every tree and every blade of grass in you, may God bless every mother's son in you, and may God keep the Old Faith in you”.

Obituary

Father William O’Leary SJ

The death of Father O'Leary in Australia will be deeply regretted by many of his past pupils. An old Mungret boy of Father O'Leary's time there writes to the Editor :

“I was at Mungret for five years, and during all that time Father O'Leary was a master there. He taught us Latin, Religious Knowledge, Mathematics and Science. But he taught us many others things besides these. I don't think there was any master of my time there the boys thought more of, or who had more influence with them. For all his lack of inches - he only looked about 5ft. 4ins, in spite of the black hair brushed straight up from his forehead - he was a most virile personality. I will always carry with me as one of the clearest memories of Mungret the picture of Father O'Leary pacing up and down the stone corridor as we went on our way to Mass, wearing his biretta and with his head sunk on his chest for all the world like Napoleon”.

For a man of his intellectual attainments allied as they were in him with a natural agility of mind and speed of accomplishment - it must have been a heart-breaking task to expound the elements of euclid to a junior grade class not specially gifted above their fellows. Only once in my time did I ever see it overcome him, and that was an occasion that none who saw will ever forget. One day in dealing with a boy whom the Lord never meant to learn euclid, he allowed himself to be betrayed into one or two natural expressions of impatience - just so much and no more. It made no impression on us nor on the boy concerned - we were I fear a thick-skinned lot - but next day when the class began, Father O'Leary called out the boy and apologised to him coram publico in terms which penetrated to our subconscious preceptions far deeper than any sermon. Talking of sermons reminds me that he was the boys' favourite preacher and confessor. He had a deep musical voice and a gift of oratory and also an ability to teach elocution which were all his own. I don't know if elocution is still taught in the schools or if it has been crowded out by the modern programme : to judge by the sort of thing one hears in “talks” from Radio Éireann even from possessors of University Degrees - the art of speaking and reading aloud is a lost one. Anyone who ever was in Father O'Leary's class or in one of his plays learned how to open his mouth and sound his consonants. He used to teach us Byron's poem about the Assyrian coming down like a wolf on the fold - I have every word of it yet - and when you came to the line ‘With the dew on his brow and the rust on his mail’ - woe betide you if you put a ‘Jew sitting on the poor man's brow’.

Science was, of course, his first love, but even that gave way before his love for Ireland. To hear him speak of Irish history or to listen to him sing ‘The West's Awake’, as we so often did was to know that the fire that burned in the breast of his distinguished father burned just as fiercely in his own. He must have known when he left Ireland in 1929 that the chances of his ever seeing home again were very small how hard that thought must have been those of us who knew him can well realise. He went like so many other Irishmen - and Mungret men have gone - where duty called him, and if he rests at last far from his own land that he loved so well, there lie around him the bones of many of his kith and kin to foregather at the resurrection. All the boys of his time in Mungret will join with me in a prayer for one than whom no one stood higher in our affections as a priest, a master, or a friend”.

Died : 22 May 1929, North Sydney, Sydney, New South Wales, Australia

Edward Francis Pigot (1858-1929), Jesuit priest, astronomer and seismologist, was born on 18 September 1858 at Dundrum, near Dublin, son of David Richard Pigot, master of the Court of Exchequer, and his wife Christina, daughter of Sir James Murray, a well-known Dublin physician. Descended from eminent lawyers, Edward was educated at home by tutors and by a governess. The family was very musical and Edward became a fine pianist; he was later complimented by Liszt. He studied arts and medicine at Trinity College, Dublin (B.A., 1879; M.B., B.Ch., 1882) and also attended lectures by the astronomer (Sir) Robert Ball. After experience at the London Hospital, Whitechapel, he set up practice in Dublin.

In June 1885 Pigot entered the novitiate of the Society of Jesus at Dromore, County Down. He began to teach at University College, Dublin, but in 1888, on account of ill health, came to Australia. He taught at St Francis Xavier's College, Melbourne, and from August 1889 at St Ignatius' College, Riverview, Sydney. Returning to Europe in 1892 he studied philosophy with French Jesuits exiled in Jersey, and theology at Milltown Park, Dublin. He was ordained priest on 31 July 1898. In 1899 he volunteered for the China Mission and was stationed at the world-famous Zi-Ka-Wei Observatory, Shanghai. In 1903, again in poor health, he spent some months working in Melbourne and at Sydney Observatory, and taught for a year at Riverview before returning to Zi-Ka-Wei for three years. Tall and lanky, he came finally to Sydney in 1907, a frail, sick man. He had yet to begin the main work of his life.

On his way back to Australia Pigot visited the Jesuit observatory in Manila: he was beginning to plan an observatory of international standard at Riverview. He began meteorological observations there on 1 January 1908. As terrestrial magnetism could not be studied because of nearby electric trams, he decided to set up a seismological station as the start of the observatory. The Göttingen Academy of Sciences operated the only fully equipped seismological station in the southern hemisphere at Apia, Samoa: a station in eastern Australia would also be favourably situated to observe the frequent earthquakes that occur in the south-west Pacific Ocean. Assisted by the generosity of L. F. Heydon, Pigot ordered a complete set of Wiechert seismographs from Göttingen, and visited the Apia observatory. Riverview College Observatory opened as a seismological station in March 1909. Seismological observations continue to be made there.

A great traveller despite his teaching duties, Pigot visited Bruny Island, Tasmania (1910), the Tonga Islands (1911) and Goondiwindi, Queensland (1922), to observe total solar eclipses; and observatories in Europe in 1911, 1912, 1914 and 1922 and North America in 1919 and 1922. He made observations of earth tides in a mine at Cobar (1913-19), collaborated with Professor L. A. Cotton in measurements of the deflection of the earth's crust as Burrinjuck Dam filled (1914-15) and performed Foucault pendulum experiments in the Queen Victoria Market building, Sydney (1916-17). On 1 September 1923 F. Omori, a leading Japanese seismologist, observed with Pigot a violent earthquake being recorded in the Riverview vault; it turned out to have destroyed Tokyo, with the loss of 140,000 lives.

Fr Pigot was a member of the Australian National Research Council from 1921, president of the State branch of the British Astronomical Association in 1923-24 and a council-member of the Royal Society of New South Wales in 1921-29. On his way back from the Pan-Pacific Science Congress in Tokyo (1926), he visited the observatory at Lembang, Java, where he planned a programme of study at Riverview Observatory of variable stars. Between 1925 and 1929 Pigot measured solar radiation at Riverview and Orange, particularly in relation to long-range weather forecasting. He was seeking a site of high elevation above sea-level for this work, when he contracted pneumonia at Mount Canobolas. He died at North Sydney on 22 May 1929 and was buried in Gore Hill cemetery.

Sir Edgeworth David paid tribute to Pigot:
It was not only for his profound learning that scientists revered him. They could not fail to be attracted by his magnetic personality, for though frail and often in weak health, he ever preserved the same charming and cheerful manner, and was full of eagerness and enthusiasm in discussing plans for the better pursuit of scientific truth. Surely there never was any scientific man so well-beloved as he.

◆ HIB Menologies SJ :
Paraphrase/Excerpts from an article published in the “Catholic Press” 30/05/1929
“The late Father Pigott, whose death was announced last week in the ‘Press’, was born at Dundrum Co Dublin 18/09/1858, of a family which gave three generations of judges to the Irish Bench. He himself adopted the medical profession, and having taken his degree at Trinity, he practiced for a few years in Dublin and at Croom, Co Limerick. While studying at Trinity he made his first acquaintance with astronomy, when he heard a course of lectures by the famous Sir Robert Ball, then head of the Observatory at Dunsink, and Astronomer Royal of Ireland.
In 1885 the young Doctor, already noted for his charming gentleness and self-sacrificing charity entered the Novitiate of the Society of Jesus at Dromore. he made his first visit to Australia as a Scholastic in 1888, and he taught for four years at Xavier College Kew, and Riverview Sydney. Naturally his department was Science.
In 1892 he was sent to St Helier in Jersey to study Philosophy with the French Jesuits who had been expelled from France. It was here that he began his long battle with frailty and illness, during which he achieved so much for scientific research over his 70 years. He did his Theology at Milltown and was Ordained 1899. Two years later he volunteered to join the French Jesuits in China, and this required of him not only his scientific zeal, but also his spiritual and missionary ones. he did manage to master the Chinese language for his work, and he used to tell amusing stories of his first sermons against himself and his intonations. His health was always threatening to intervene, and so he went to work at the Zi-Kai-Wei Observatory near Shanghai. The work he did here on the Chinese Mission was to reach his fulness in the work he later did over many years in Australia, and where he went to find the climate which suited his health better. He received much training at Zi-Kai-Wei and in photography and study of sunspots at Ze-se, which had a twin 16 inch telescope.
1907 saw him back in Australia and he set about founding the Observatory at Riverview, while teaching Science. By his death, this Observatory had a range and capacity, in terms of sophisticated instruments, which rivalled the best Government-endowed observatories throughout the world. Whilst he had the best of equipment, he lacked the administrative personnel necessary to record all the data he was amassing. His great pride towards the end was in his spectroscope for the work on Solar Radiation where he believed that ‘Long-distance weather forecasts will soon be possible, though not in my time’ (Country Life, 29/04/1929). Current farmers and graziers will owe him a lot in the future.
The scientific work at Riverview has received recognition in Australia. Edward’s interests in the Sydney Harbour Bridge, his experiments in earth tremors at the construction of the Burrenjuck Dam, geophysics at the Cobar mines, pendulum experiments in the Queen Victoria Markets of Sydney. In 1910 he took part in a solar eclipse expedition to Tasmania, and in 1911 on the ship Encounter a similar trip to the Tongan Islands, and the Goondiwindi Expedition of 1922.
In 1914 he was appointed by the Government to represent Australia at the International Seismological Congress at St Petersburg, though war cancelled that. In 1921 he was a member of the Australian National Research Council and sent to represent them to Rome at the 1922 first general assembly of the International Astronomical Union and the International Union of Geoditics and Geophysics. He was president of the NSW branch of the British Astronomical Association, and a member of the Royal Society of NSW. In 1923 the Pan-Pacific Science Congress was held in Australia, and during this Professor Omori of Japan was at Riverview watching the seismometers as they were recording the earthquake of Tokyo, Dr Omori’s home city. In 1926 he went to the same event at Tokyo, and later that year was elected a member of the newly formed International Commission of Research of the Central International Bureau of Seismology.
From an early age he was a passionate lover of music, and this came from his family. he gave long hours to practising the piano when young, and in later life he could play some of the great pieces from memory. He was said to be one of the finest amateur pianists in Australia. It often served as a perfect antidote to a stressful day at the Observatory."

Many warm-hearted and generous tributes to the kindness and charm for Father Pigott’s personal character have been expressed by public and scientific men since his death. Clearly his association with men in all walks of life begot high esteem and sincere friendship. Those who knew him in his private life will always preserve the memory of a kindly, gentle associate, and of a saintly religious.”

Edward Pigot's family was of Norman origin and settled in Co Cork. Ireland. The family was a famous legal family in Dublin. He was the grandson of Chief Baron Pigot, son of judge David Pigot, brother of Judge John Pigot. He was the fourth of eight children, and was educated at home by a governess and tutors. The family was very musical, Edward playing the piano.
Pigot went to Trinity College, Dublin, and graduated BA in science in 1879. His mentor at the university in astronomy was Sir Robert Ball, then Royal Astronomer for Ireland and Professor of Astronomy. Pigot then studied medicine and graduated with high distinction in 1882, and after postgraduate studies practiced in Baggot Street, Dublin.
However, Pigot gave up this practice to join the Society of Jesus, 10 June 1885, at the age of 27.
After a short teaching period at University College, Dublin, Pigot was sent to Australia in 1888 because of constant headaches, and he taught physics and physiology principally at St Ignatius College, Riverview, 1890-92. He returned to Europe for further studies, philosophy in Jersey with the French Jesuits, 1892-95, and theology at Milltown Park, Dublin, where he was ordained priest in 1898. Tertianship followed immediately at Tullabeg.
At the age of 41 and in ill health, Pigot volunteered for the Chinese Mission in 1899, and was stationed at Zi-ka-Wei, near Shanghai, working on a world famous observatory, where
meteorology, astronomy and terrestrial magnetism were fostered. Pigot specialised in astronomy and also studied Chinese. Like other missionaries of those days, he grew a beard and a pigtail. However, his health deteriorated and he was sent to Australia in 1903 for a few years. He then returned to Shanghai, 1905-07, before returning to Riverview in 1908.
After visiting the Manila Observatory, he formulated plans for starting an observatory at Riverview, an activity that he believed would bring recognition for the excellence in research that he expected at the Riverview observatory He believed that seismology was best suited to the location. Pigot obtained the best equipment available for his work, with the gracious benefaction of the Hon Louis F Heydon, MLC. He personally visited other observatories around the world to gain ideas and experience, as well as attending many international conferences over the years. One result of his visit to Samoa was the building and fittings for the instruments in the half-underground, vaulted, brick building at Riverview. Brs Forster and Girschik performed the work. Some instruments, called the Wiechert Seismographs, came from Germany.
He became a member of the Australian National Research Council at its inception in 1921, and foundation member of the Australian Committee on Astronomy, as well as that on Geodosy and Geophysics. He served on the Council of the Royal Society of NSW, and was President of the British Astronomical Association (NSW Branch), 1923-24.
The upkeep of the Riverview observatory was borne by the Australian Jesuits and Riverview. Family and friends also gave funds for this work. When he died from pneumonia, he left at the Riverview observatory five double-component seismometers, two telescopes fully equipped for visual and photographic work, a wireless installation, clocks specially designed for extreme accuracy, an extensive scientific library, a complete set of meteorological instruments, and a solar radiation station, possessing rare and costly instruments.
Pigot's work at Riverview included working on scientific problems of the Sydney Harbour Bridge, experiments at the construction of the Burrenjuck Dam, geophysics at the Cobar mines, and pendulum experiments in the Queen Victoria Market Buildings in Sydney In 1910 he took part in a solar eclipse expedition to Tasmania. In April 1911 he went with the warship Encounter on a similar expedition to the Tongan Islands in the Pacific, and was prominent in the Goondiwindi Solar Eclipse Expedition in 1922.
Pigot was appointed by the Commonwealth Government to represent Australia at the International Seismological Congress at St Petersburg in 1914. He was secretary of the seismo-
logical section of the Pan-Pacific Science Congress in Sydney, 1923, and in 1926, once more represented the Commonwealth Government as a member of the Australian Delegation at the Pan-Pacific Congress, Tokyo. In 1928 he was elected a member of an International Commission of Research, which was part of the International Bureau of Seismology, centered at Strasbourg.
He was highly esteemed by his colleagues for his friendship, high scholarship, modest and unassuming demeanour, and nobility of character. Upon his death the rector of Riverview received a letter from the acting-premier of New South Wales, describing Pigot as one of the state's “most distinguished citizens”, and Sir Edgeworth David praised his magnetic personality and eagerness and enthusiasm in discussing plans for the better pursuit of scientific truth.
Edward Pigot, tall and lanky, frail and often in weak health, was also a fine priest, always helper of the poor, and exemplary in the practice of poverty. He did pastoral work in a quiet way. On his scientific expeditions, he was always willing to help the local clergy and their scattered flocks. He was genuinely modest, humble, and courteous to all. Yet he was naturally a very sensitive and even passionate man, with a temperament that he did not find easy to control. He disagreed strongly with Dr Mannix on the issue of conscription - the Pigots were decidedly Anglo-Irish - and positively refused to entertain the idea of setting up an observatory at Newman under the archbishop's aegis.
His extremely high standards of scientific accuracy and integrity made it difficult for him to find an assistant he could work with, or who could work with him. George Downey, Robert McCarthy, and Wilfred Ryan, all failed to satisfy. However, when he met the young scholastic Daniel O'Connell he found a man after his own heart. When he found death approaching he was afraid, not of death, but because O’Connell was still only a theologian and not ready to take over the observatory. Happily, the Irish province was willing to release his other great friend, William O'Leary to fill the gap.

Fr Pigot attended the Pan-Pacific Science Congress in Tokyo as a delegate representing the Australian Commonwealth Government. He was Secretary to the Seismological Section, and read two important papers. On the journey home he spent some time in hospital in Shanghai, and later touched at Hong Kong where he met Frs. Byrne and Neary.

Irish Province News 3rd Year No 1 1927

Lavender Bay, Sydney :
Fr. Pigot's great reputation as a seismologist was much increased during the present year by his locating of the Kansu earthquake within a few hours of the first earth tremors. “Where he deserted medicine,” the Herald writes, “that profession lost a brilliant member, but science in general was the gainer. Dr Pigot is one of the world's leading authorities on seismology, and can juggle azimuths and seismometers with uncanny confidence”.

Obituary :
Fr Edward Pigot
Fr Pigot died at Sydney on May 21st. He caught a slight cold which in a few days developed into T. B. pneumonia. He was very frail, and had no reserve of strength left to meet the attack. The Archbishop presided at the Requiem. The Government sent a representative. The papers were all very appreciative.

Fr Pigot was born at Dundrum, Co. Dublin on the 18th September 1858, educated at Trinity College, Dublin, where he studied medicine, and took out his degrees - MB, BCh, in 1882. For the three following years he was on the staff of Baggot St Hospital, Dublin, and was Chemist with his uncle, Sir James Murray, at Murray's Magnesia works. He entered the Society at Loyola House, Dromore, Co. Down on the 10th June 1885. He spent one year at Milltown Park as junior, and then sailed for Australia. One year at Kew as prefect, and three years at Riverview teaching chemistry and physics brought his regency to an end. Fr. Pigot spent three years at Jersey doing philosophy, as many at Milltown at theology, and then went to Tullabeg for his tertianship in 1898. At the and of the year a very big event in his life took place. He applied for and obtained leave to join the Chinese Mission of the Paris province. For a year he worked in the Church of St. Joseph at Yang-King-Pang, and for two more at the Seminary at Zi-Kai-Wei, but the state of his health compelled a rest, and in 1913 we find him once more at Riverview teaching and trying to repair his shattered strength. He seems to have, in some measure, succeeded, for, at the end of the year he returned to his work at Zi-kai-wei. The success however was short lived. He struggled on bravely for three years when broken health and climatic conditions forced him to yield, and he asked to be received back into the Irish Province. We have it on the highest authority that his reasons for seeking the Chinese Mission were so a virtuous and self-denying, that he was heartily welcomed back to his own province. In 1907 he was stationed once more at Riverview, and to that house he belonged up to the time of his happy death in 1929.
It was during these 22 years that Fr. Pigot's greatest work was done - the founding and perfecting of the Riverview Observatory. The story is told by Fr. Dan. O'Connell in the Australian Jesuit Directory of 1927.
Fr. Pigot's first astronomical training was at Dunsink Observatory under the well known astronomer “Sir Robert Ball”. Then, as mentioned above, many years were passed at the Jesuit Observatory at Zi-kai-wei.
For some years previous to his return to Riverview, earthquakes had been receiving more and more attention from scientists, Excellent stations had been established in Europe and Japan, but the lack of news from the Southern Hemisphere greatly hampered the work of experts. It was the very excellent way in which Fr. Pigot supplied this want that has won him a high place amongst the worlds scientists.
Thanks to the kindness of relatives and friends, and to government help, Fr. Pigot was able to set up at Riverview quite a number of the very best and most up-to-date seismometers, some of which were constructed at government workshops under his own personal supervision. At once, as soon as things were ready, Fr Pigot entered into communication with seismological stations all the world over. When his very first bulletins were received in Europe, Riverview was gazetted as a “first-order station”, and the work done there was declared by seismologists everywhere as of first-rate importance. At the time of his death Fr Pigot had established telegraphic communication with the International Seismological Bureau at Strasbourg.
The study of earthquakes was only one of Fr. Pilot's activities, He was able, again through the generosity of his friends, to put up at Riverview, a first class astronomical observatory. It has four distinct lines of research :

  1. The photography of the heavens.
  2. Photographs of sunspots
  3. Study of variable stars.
  4. Micrometre measurements of double stars.
    Fr Pigot also took part ill a number of solar eclipse expeditions to Tasmania in May 1910, in April 1911 to Tonga, and to Goondiwindi in 1922.
    Finally, and perhaps most difficult of all, he established at Riverview a solar radiation station. The object of such a station is to determine the quantity of heat radiated out by the sun. This quantity of heat is not constant, as was thought but variable. The work is expensive, and of a highly specialised nature. It was hoped that in course of time it would have very
    practical results, amongst them being the power of being able to forecast changes in climate and weather over much longer periods than is at present possible. The necessary funds were collected by a Solar Radiation Committee formed at Sydney, Supplemented by a legacy from a relative of Fr Pigot's.
    Fr Pigot's ability as a scientist is shown by the number of important positions he held, and by the number of missions entrusted to him. He was elected President of the N. S. W. branch of the British Astronomical Association in 1923 and 1924.
    He was a member of the Council of the Royal Society of NSW for several years. On the occasion of the International Seismological Congress to be held at. St. Petersburg in l914 he was appointed by the Commonwealth Government as delegate to represent Australia. Owing to the war the Congress was not held. It was on this occasion that Fr Pigot was sternly refused permission as a Jesuit to enter Russia. Even the request of the British ambassador at St Petersbourg for a passport was of no avail. It was only through the intercession of Prince Galitzin the leading Seismologist in Russia and a personal friend of the Russian Foreign Minister that the permit was granted.
    He went to Rome in 1922 as delegate from the Australian National Research Council to the first General Assembly of the Astronomical Union.
    He was Secretary of the Seismological Section at the Pan-Pacific Science Congress in Australia 1923.
    He was appointed by the Commonwealth Government as one of an official delegation of four which represented Australia at the Pan-Pacific Congress in Tokyo 1926.
    Fr Pigot was a great scientist he was also a fine musician an exquisite pianist and a powerful one. He was said Lo be amongst the finest amateur pianists in Australia. Once during a villa he was playing a piece by one of the old masters. In the same room was a card party intent on their game. Fr Pigot whispered to a friend sitting near the piano “mind the discord
    that's coming”. It came, and with it came howl and a yell from the card players. In the frenzy of the moment no one could tell what was going to come next. But, as Fr Pigot continued to play a soothing bit that followed, a normal state of nerves was restored, and the players settles down to their game.
    He was a great scientist, and a fine musician, but, above all and before all, he was an excellent religious. In the noviceship too much concentration injured his head, and he felt the effects ever afterwards. It affected him during his missionary work and during his own studies. His piety was not of the demonstrative order, but he had got a firm grip of the supernatural, and held it to the cud. He knew the meaning of life, the meaning of eternity and squared his life accordingly.
    His request for a change of province was in no way due to fickleness or inconstancy. He had asked a great grace from Almighty God, a favour on which the dearest wish of his heart was set, and he made a supreme, a heroic sacrifice to obtain it. That gives us the key note to his life, and it shows us the religious man far better than the most eloquent panegyric or the longest list of virtues that adorn religious life could do. Judged by that sacrifice he holds a higher and a nobler place in the world of our Society that that which his genius and unremitting hard work won for him in the world of science.
    A few extracts to show the esteem if which Fr. Pigot was held by externs :
    Father Pigot's death “removes a great figure not only from the Catholic world but also from the world of science. His fame was world-wide. He was one of the worlds' most famous seismologists”.
    “By his death Australian science and the science of seismology have sustained a loss that is almost irreparable. He initiated what now ranks among the very best seismological observatories in the world”.
    “He was able to secure the best instruments for recording the variations in heat transmitted from the sun to the earth for his Solar observatory at Riverview, and to make observations, which science in time will rely upon to put mankind in the possession of long range forecasts as to future rainfall and weather in general”.
    “Dr. Pigot told me that after some years it would be possible to forecast the weather' two seasons ahead”.
    “ Dr. Pigot was one of the brightest examples of simple faith in a Divine purpose pervading all the universe”.
    “It was not only for his profound learning that scientists reverenced him. They could not fail to be attracted by his magnetic personality, for though frail and often in weak health he ever preserved the same charming and cheerful manner, and was full of eagerness and enthusiasm in discussing plans for the pursuit of scientific truth. Surely there never was any scientific man so well beloved as he”
    “Those who knew him in his private 1ife will always reserve the memory of a kindly, gentle associate, and of a saintly religious”.

Obituary : Fr Edward Pigot
The following items about Fr. Pigot's youth have been kindly supplied by his brother.
“He was born the 18th Sept. 1858 at Meadowbrook, Dundrum, Co. Dublin His first tuition was at the hands of governesses and private tutors, after which he attended for some years a day school kept by H. Tilney-Bassett at 67 Lower Mount St.
Concurrently, under the influence of his music Master, George Sproule, his taste for music began to develop rapidly. Sproule had a great personal liking for him, and took him on a visit to Switzerland. Many years afterwards Fr. Pigot heard that Sproule (who had taken orders in the Church of England) was in Sydney. He rang him up on the telephone, without disclosing identity, and whistled some musical passages well known to both of them. Almost at once Sproule knew and spoke his name.
Even as a schoolboy, I can recall how he impressed me by his superiority, by his even temper, command of himself under provocation, his generosity, his studiousness and his steadiness generally.
He entered Trinity about 1879. In the Medical School, he had the repute of a really serious student. He was especially interested in chemistry and experimental physics. Astronomy was outside his regular course, but I remember visits to Dunsink observatory, His studies seemed to he regulated by clockwork.
Before setting up as a doctor in Upper Baggot Street, he was resident medical attendant at Cork Street Fever Hospital, and the Rotunda Hospital, and at the City of Dublin Hospital. When in private practice at Baggot Street, he was not financially successful. I have the impression that his serious demeanour and grave appearance were against him, But I have better grounds for believing that his work amongst the poor, his unwillingness to charge fees to the needy, operated still more in the same direction. We often heard, but not from him, of his goodness to the poor. This was the time that he announced to us his desire to join the Jesuit Order. May I add that if there was one event in Ned’s life for which I have long felt joy and thankfulness, it was his desire to enter your Order.
Years after he had left Dublin, one of his prescriptions had become locally famous, and was ordered from the chemist as “a bottle of Kate Gallagher, please”, Kate having been one of his poor friends”.

Riverview :

In 1923 Fr. Pigot built a Solar Radiation Station at Riverview, and started a programme of research on the heat we receive from the sun. This work has now been finally wound up. The valuable instruments, which are the property of the Solar Radiation Committee, were offered on loan to Commonwealth Solar Observatory, Mt. Strombo, Canberra. The offer was accepted and the instruments were sent by lorry to Mt. Strombo on February 7th. The results of the work have been prepared for publication and are now being printed. This will be the first astronomical publication to be issued by the Observatory since December 1939. Shortage of staff and pressure of other work during the war were responsible for interrupting that branch of our activities. Another number of our astronomical publications is now ready and about to be sent to the printer. We have started a new series of publications: Riverview College Observatory Geophysical Papers." The first three numbers are now being printed and will be sent to all seismological Observatories and to those scientists who may be interested.

Father Edward Pigott 1859-1929
Fr Edward Pigott was born in Dundrum Dublin on September 18th 1858, of a family which gave three generations to the Irish Bench. Edward himself became a Doctor of Medicine, taking a degree at Trinity College, and practising first in Dublin, then in Croom County Limerick. In 1885, the young doctor entered the Society at Dromore, and made his first visit to Australia in 1888, where he spent four years teaching at Xavier College.

Ordained in 1899, two years later he volunteered for the Chinese Mission. He learned the Chinese language in preparation for his work, and for a while tested the hardships of active service with the French Fathers of the Society. He used recall afterwards with a wry smile his efforts to preach in Chinese, and how he hardly avoided the pitfalls on Chinese intimation. I;; health, which dogged him all his life, sent him to the less arduous work of Assistant at Zi-Kai-Wei Observatory, near Shanghai. This was the beginning of his brilliant career as an astronomer.

After six years in Shanghai, during which he mastered his science, he returned to Australia in 1907 and started the Observatory at Riverview. He started with a small telescope and a few elementary instruments for recording weather changes, and finally made of Riverview, one of the leading Observatories of the world. Honours and distinctions were showered on him. He was appointed by the Government to represent Australia at St Petersburg in 1914, in Rome in 1922, at the International Astronomical Union, and the Pan Pacific Science Congress in 1923, held in Australia.

In spite of his prominence in the scientific world, Fr Pigott remained always to his brethren a kindly and gentle associate and a saintly religious.

He died on May 22nd 1929, aged 70 years, battling with ill health all his life. A strong spirit housed in a frail body.

Father Pigot’s Return

On April 11th, the Community and boys went down to the College Wharf to welconie Father Pigot SJ, back to Riverview, after his extended tour through Europe. He had been absent about seven months, and during that time visited most of the leading seismological observatories on the Continent and in the British Isles. He had purposed visiting also some other observatories in the United States, Canada and Japan, on his return journey to Sydney; but a severe attack of pleurisy in Italy, during the trying mid-winter season, obliged him to hasten back to the warm Australian climate, without even being able to accept the kind invitation of Prince Galitzin to spend a few days as his guest at St Petersburg. All have heard of Father Pigot's application to the Foreign Office, London (on hearing accidentally, a day or two before, of the existence of a Russian law prohibiting members of the Jesuit Order. from entering Russia) to obtain from the Russian Government the necessary permission, in view of a short visit to Prince Galitzin's Seismological Observatory at Pulkovo. The request of the Foreign Office was refused, as everyone knows, but apparently the sequel of the story is not so generally known.

It was during liis stay at Potsdam (Berlin) that Father Pigot received the unfavourable reply from Westminster. He at once acquainted Prince Galitzin with the refusal, whereupon the distinguished seismologist made a strong representation, resulting in his Government inimediately withdrawing the prohibition. His kind letter to Father Pigot acquainting him with the Russian Government's concession, and a formal communication to the same effect from the British Foreign Office, arrived during Father Pigot's convalescence, but a delay in Europe of three months would have been necessary to allow the severe winter in St. Petersburg to pass before he could, without risk of relapse, have availed himself of the concession and kind invitation.

Father Pigot has asked us to record his deep feeling of appreciation of the cordial greetings of the Community and boys, when they most kindly came down to welcome him at the wharf,

We give a photograph of Father Pigot, and another of a group of distinguished seismologists assembled together from various parts of the world, at Manchester, for the International Seismological Congress (1911).

Fr Pigot’s Visit to Europe : The InternationalAstronomical Union - First General Assembly, Rome, May 1922

The First General Assembly of the Inter national Astronomical Union commenced its deliberations in May this year, in the Academy of Science (the old Corsini Palace), at Rome. That Australia in union with the other nations, might be represented at the two main conferences (Astronomy, and Geodesy and Geophysics), the Commonwealth Government having paid the necessary subscriptions, three delegates - Dr T M Baldwin (Government Astronomer for Victoria), Mr G F Dodwell (Government Astronomer for South Australia), and Father Pigot represented the Australian National Research Council at the General Assembly.

The purpose of the Union, as set forth in this report, is - (I) “To facilitate the relations between astronomers of different countries where international co-operation is neces sary or useful; and, (2) To promote the study of astronomy in all its departments”. Each country adhering to the Union has its own National Research Council, which forms the National Committee for the promotion and co-ordination of astronomical work iul the respective countries, especially regard ing their international requirements. The countries at present adhering to the Union are Australia, Belgium, Brazil, Canada, Czecho-Slovakia, Denmark, France, Great Britain, Greece, Holland, · Itály, Japan, Mexico, Poland, South Africa, Spain, and the United States.
When Father Pigot left us suddenly in March, we felt that indeed there must be “something on” in the scientific world to draw him away at short notice from his beloved observatory. But the meetings of the Astronoinical Union, despite their international importance, were not his only objective. His itinerary, as we shall see, was a long one, and one of his chief aims while in Europe and America, was to inspect the principal Astronomical, Seismological and Solar Radiation observatories, and to get in personal touch with the foremost scientists. of the northern hemisphere.

Upon arrival in Europe he spent some time, successively, in the observatories of Marseilles, Nice, Geneva, and Zurich, In April he attended the Seismological Congress at Strasbourg, and then went on to Rome, taking in on his way, the Arcetri Observatory at Florence (situated, by the way, a stone's-throw from Galileo's house). While in Rome at the Conferences of the Astronomical and Geophysical Unions, he was, of course, in constant touch with Father Hagen S J, the Director of the Vatican Observatory, and though he does not say so, we may well imagine that his feelings were not untinged with sadness as he ascended the great staircase of the Government Observatory-the great Roman College of the Jesuit Order, before a Ministry more sectarian than honest usurped it.

Before the Conferences of the General Assembly were over, the delegates were in vited by His Holiness the Pope to a special audience in the Throne Room of the Vatican. It was accepted by all. Before congratu lating themselves on the splendid success of their meetings, His Holiness spent some time in chatting freely with most of those present, shook hands with them all, and be fore their departure, had a photo taken by the Papal photographer in the Court of St. Damasus.

The Roman Conferences over, Father Pigot lost no time in getting on his way. His first call was at the Geophysical Institute of Göttingen. Then on to Munich, and to Davos Platz for a private meeting on Sky and Solar Radiation with Dr Dorno (Head of Davos Observatory), Professor Maurer (Head of the Swiss Weather Bureau), and Professor Kimball (of the Solar Radiation Station of the Washington Weather Bureau).

The Paris Observatory - one of the largest in Europe - came next, and after spending some time here, he went on to the Royal Observatory at Brussels. Before leaving Beigium, he had time to run down to the Jesuit Observatory at Valkenberg, near the Dutch frontier, after which he returned to Greenwich. At a dinner of the Royal Astronomical Society, at which nine of the delegates were entertained, Father Pigot's health was proposed by Father Cortie SJ, of the Stonyhurst Observatory.

After a brief visit to Ireland, Father Pigot started out on his return journey, via America. One of his first visits on the other side was to the Jesuit Seismological Observatory at Georgetown University, Washington. While in the Capital, he spent some time at the Carnegie Observatory (Terrestrial Magnetisın), the Weather Bureau Solar Radiation Station, the Astro-physical Observatory of the Smithsonian Institute (where he renewed acquaintance with a valued friend, Dr Abbot, the President), the Bureau of Standards, and the Office of the Geodetic Survey. He was much impressed, as in 1919, with the up-to-date appliances of the Americans, and with the thoroughness of their scientific work.

Leaving Washington, he called at The Observatory of Harvard University (Boston, Mass.), and at the University of Detroit, where he found Professor Hussey, who knows Riverview well and has been in Australia more than once on scientific work. Yerkes Observatory, near Chicago, where is installed the largest Refractor in the world, claimed him next, after which he proceeded to the famous Mt Wilson Observatory at Pasadena (near Los Angeles, Col.). Here Father Pigot was in his element, for it is with Dr. Abbott, more especially than any one else, that he has discussed the details of the projected Solar Radiation Observatory at Riverview, and from him received the most valuable assistance.

Passing on to the Lick Observatory (Mt Hamilton, N Cal), he just missed Professor Campbell, who had left for Australia four days before as a member of the Wallal (WA) Eclipse Expedition. Professor Tucker, however, the locuin tenens, showed hiin every kindness.

Father Pigot's final visit before embarking for Australia was to the Canadian Government Observatory (Victoria, BC), which possesses the most powerful telescope in the British Empire (73in. Reflector). In the realm of instrumental astronomy Canada has outstripped all the other Dominions, and even the Mother Country herself.

It is superfluous to emphasise the im tiense value Father Pigot derived from his visits to the leading scientific men of the world, picking up hints, seeing new methods, and the most modern appliances for the subject nearest and dearest to his heart.

That the Riverview Observatory will gain by his experiences, and that the new Solat Radiation Observatory will receive a new fillip, goes without saying:

Obituary

Edward F Pigot

Father Pigot was born at Dundrum, County Dublin, on September 18, 1858. He adopted the medical profession, and practised for a few years in Dublin. In 1885 he entered the Novitiate of the Society of Jesus at Dromore, County Down. He made his first visit to Australia as a Jesuit scholastic in 1888, and taught for four years at Xavier College, Melbourne, and St Ignatius' College, Sydney. Naturally, his department was science. He completed his theological studies in Milltown Park, Dublin, and was ordained in the summer of 1899. Two years later he volunteered for the arduous China Mission, where the French Fathers of the Society of Jesus were endeavouring to Christianise the vast pagan kingdom - an act revealing fires of missionary zeal and personal devotion probably unsuspected by those who knew only the retiring scientist and scholar of later years. His sacrifice was accepted, and recompensed in a striking manner. He did, indeed, master the Chinese language in preparation for missionary labours, and for a while tasted the hardships of active service.

He returned to Australia in 1907, and immediately set about founding an observatory at Riverview, while teaching science on the college staff. When death called him he had gathered at Riverview five double-component seismometers, two telescopes fully equipped for visual and photographic work, a wireless installation, clocks specially designed for extreme accuracy, an extensive scientific library, a complete set of meteorological instruments, and what he most valued in his later years, a solar radiation, station, possessing rare and costly instruments, such as are possessed by only a few other, and these Government-endowed, stations throughout the world.

Fr. Pigot's in terest in the scientific problems of the Sydney Harbour Bridge, his experiments at the construction of the Burrenjuck Dam, in geophysics at the Cobar mines and elsewhere, his pendulum experiments in the Queen Victoria Market Buildings in Sydney, are well known. In 1910 he took part in a solar eclipse expedition to Tasmania; in April, 1911, he went with the warship Encounter on a similar expedition to the Tongan Islands in the Pacific, and was prominent in the Goondi windi Solar Eclipse Expedition in 1922.

Father Pigot was appointed by the Commonwealth Government to represent Australia at the International Seismological Congress at St. Petersburg in 1914. The outbreak of war prevented the Congress being held. In 1921 he was chosen as a member of the Australian National Research Council, and in 1922 went to Rome as its representative at the first general assembly of the International Astronomical Union, and of the International Union of Geodetics and Geophysics. He was elected President of the NSW branch of the British Astronomical Association in 1923 and 1924. For many years he was a member of the Council of the Royal Society of NSW.

At the Pan-Pacific Science Congress, held in Australia in 1923, Father Pigot was secretary of the seismological section. In 1926 Father Pigot was once more chosen by the Commonwealth Government as a member of the Australian Delegation at the Pan-Pacific Congress, held in Tokyo, in October, 1926. In December of last year he received word from the secretary of the Central International Bureau of Seismology, Strasburg, that he had been elected member of an International Commission of Research, formed a short time previously at a congress held in Prague, Czecho-Slovakia.

Many warm-hearted and generous tri butes to the kindliness and charm of Father Pigot's personal character have been expressed by public and scientific men since his death. Clearly his associa tion with men in all walks of life begot high esteem and sincere friendship. Those who knew him in his private life will always preserve the memory of a kindly, geritle associate, and of a saintly religious. RIP

Premier's Office, Sydney, N.S.W.
22nd May, 1929.
Dear Sir,
At a meeting of the Cabinet this morning mention was made of the sad loss this State has sustained in the death of Reverend Father Pigot, one of its most distinguished citizens. I was invited by my colleagues to convey to you, as Principal of the eminent educational establishment, with which Father Pigot had the honour to be associated, an. expression of the deepest sympathy from the Members of the New South Wales Ministry.

The memory of Father Pigot, who was a per sonal friend of many of us, will be kept ever green by reason of his high scholastic and scien tific attainments, modest and unassuming demean our, and ni sy of character.
Yours faithfully,

E. A. BUTTENSHAW,
Acting Premier,


The Rev Father Lockington SJ, StIgnatius' College, Professor

H, H. Turner, of the British Association and the International Seismological Summary, speaks of “the splendid work done by Father Pigot in seismology; Riverview has been for many years our standby in the discussion of earthquakes near Australia”.


Professor Sir Edgeworth David, quoted in the “Catholic Press”, writes:

“By his death Australian science and the science of seismology have sustained a loss that is almost irreparable. He initiated what now ranks among the very best seismological observatories in the world. He was able to secure the best in struments for recording the variations in heat transmitted from the sun to the earth for his solar observatory at Riverview, and to make observa- . tions. This science in time we will rely upon to put mankind in possession of long range forecasts as to future rainfall and weather in general.

He was well known to all leading physicists and astronomers, and entirely because of his great reputation the University of Sydney was able to borrow for a period of six years some extremely valuable pendulums from Germany for measuring small displacements of the earth's crust at the great reservoir at Burrenjuck.

It was not only for his profound learning that scientists reverenced him. They could not fail to be attracted by his magnetic personality, for though frail and often in weak health, he ever preserved the same charming and cheerful man ner, and was full of eagerness and enthusiasm in discussing plans for the better pursuit of seien tific truth. Surely there. never was any scientific man so well beloved as he”.

The New Seismographs at Riverview

That Seismology, and especially Seismographs, are in the air at pres ent, there can be no doubt. We have recently experienced in Sydney such a series of earthquake tremors, some of which have been usually large, and all coming on top of one another, as it were, that the subject was a common topic of conversation for several weeks. But the greatest interest centred not so much on the earthquakes as on the Riverview Seismograph that recorded them. When, a few weeks ago, the papers announced that a big and destructive earthquake had occurred so many thousands of miles away, "A big earthquake somewhere," one Melbourne Daily headed the re port-the safe announcement following that it was possibly in the sea somewhere, did much, we are sure, to nullify any exciting effect the tid ings might have had on even unsceptical readers. The news two days later, however, that a severe earthquake had taken place in Sumatra, and that 250 people had been killed, made the Riverview Seismograph not only known, but famous. With Father Pigot's permission (or, shall I say, with out Father Pigot's permission?) I purpose giving a short account of the Seismographs to accompany our illustrations,

The idea, as a mere remote possibility, of starting a Seismographical Observatory at Riverview, occurred to Father Pigot a few years ago at Zi ka-wei (Shanghai), just when leaving for Australia, where he was oblijed by ill-health to return, and received a fresh impetus when he was passing through Manilla on the voyage south. The splendid seismographical work done by the Fathers for many years at these two great Jesuit Observator ies of the Far East (not to speak of all that they have achieved in their other departments, viz., Meteorology, Terrestrial Magnetism, and Astro nomy, above all, of the tens of thousands of lives saved by their typhoon warnings during the last thirty years), was a sufficient incentive to Fr Pigot, who had been on the staff of the former Observatory for some time, to attempt a small beginning of at least one branch of similar high class work in Australia. No doubt excellent records had been obtained for several years in Australia and New Zealand by the well-known instrument of the veteran Seismologist, Professor Milne; but it was interesting to see what results would be obtained by a more modern type of Seismograph of one or other of the recent German models. Those of Professor Wiechert, of Gottingen University, were decided upon, if funds would per mit. The decision was most unexpectedly confirmed by the arrival in Syd ney shortly after, on his way home to Germany, at the expiration of his term of office as Director of the Samoa Observatory, of Dr Linke, who showed his Wiechert earthquake records to Father Pigot, at Riverview. Dr Linke, who now, by the way, is Director of the Geophysical Institute in Frankfort (Germany), has since taken the kindliest interest in our embryo Observatory.

But where was all the necessary money to come from? Needless to say, a lot of expense was involved. As two of the principal instruments are now installed, we may say that nearly the whole of the expense of the larger (horizontal) Seismograph was defrayed by our kind and generous friend and neighbour, the Hon Louis F Heydon, MLC - a man whose charity is equalled only by his love of learning and scientific progress ad majorem Dei gloriam. To the Hon Mr Heydon, therefore, for the great pioneer part he played in giving Seismology a foothold in Riverview, not Father Pigot's alone, but Riverview's warmest thanks are due. But though Seismology has certainly got a foothold in Riverview, it must be remembered that at present our Observatory is only in an embryonic con dition. Space has been provided in the building for other Geophysical re search work, to be carried out later on, when, like the Hon. Mr. Heydon, other lovers of scientific research shall have recognised in the Riverview Observatory, a work deserving of their patronage and generosity.

In July, 1908, Father Pigot paid a visit of three weeks to Samoa, where, through the kindness and courtesy of the Director of the Observa tory, Dr. Angenheister, and his assistants, he was able to study the con struction and working of the various instruments, the methods for the reduction of the records, etc. On his return, he set about erecting the building and fittings for the instruments the half-underground, vaulted, brick building (not as yet covered with its protecting mantle for tem perature), and woodwork fittings. These were admirably constructed respectively by Brother Forster SJ, and Brother Girschik SJ, with their usual indefatigable care. In the early autumn the instruments arrived from Germany, and soon afterwards they were recording tremors and earthquakes. The instruments are amongst the most modern in use at the present day, and are known as the Wiechert Seismographs or Seis mometers, named from their designer, Professor Wiechert. Until quite recently they were not numerous, being confined, with the exception of the Samoa instrument, to European Observatories. Now, however, they are being installed in various regions of the globe. The extreme delicacy of the instruments is almost incredible; an unusual weight on the floor of the Observatory (a party of visitors, for example), even at some dis tance from the instruments, would be sufficient to cause serious derange ment of the recording pens; the ocean waves dashing on the coast six miles away on a rough day are frequently recorded. It is in this extreme delicacy that the value (and, incidentally, the trouble) of the instruments consists. As a consequence they demand the most careful handling, and almost constant attention.

There are two instruments: a Horizontal Seismograph and a Vertical Seismograph, to receive, as the names suggest, the horizontal part (or component, as the scientists call it), and the vertical part respectively of the earth-waves set up by any seismic disturbance. The Horizontal Seismo graph, however, consists practically of two Seismographs in as much as it separates the waves it receives into two directions; NS and EW, giving a separate record for each, as may be seen from the two recording rolls hang ing down in front.

The horizontal is an inverted pendulum whose bob is a large iron cylindrical (or drum-shaped) mass of 1000 kilograms, or a little over a ton weight. This mass is supported on a pedestal which is poised on four springs set on a large concrete pillar built on the solid rock, and separated from the surrounding floor by an air-gap one inch wide. When an earth quake occurs in any place, that place becomes the centre from which earth waves travel in all directions, through the earth and round the earth (surface waves). These waves on reaching Riverview disturb our concrete pillar, and set the pendulum in motion. The iron mass is reduced to a "stable equilibrium” by a system of springs, so that when the base is disturbed, the large mass will not fall over, but will oscillate or swing backwards and for wards till it comes to rest again. Now, a very ingenious air-damping arrangement (the two drum-like structures over the mass) destroys the oscillation or swing set up in the mass by the first wave, so that the second and third and succeeding earth-waves will not be affected by the oscillation of the mass itself, but each wave, no matter how quickly it comes after the others, will have its own effect on the mass. Consider, for illustration sake, one of those now-antiquated punching-ball apparatus that consist of a heavy leaden circular base, into the middle of which is inserted a stout four or five-foot cane, on the top of which is fixed the punching ball. When you punch this ball it and the cane oscillate, or swing backwards and forwards (the heavy base remaining stationary). If you determine to hit out at this ball at a fixed rate, say thirty punches a minute, you cannot be certain that every blow will have its full effect on the ball-in many cases you may not hit the ball at all. But if you contrive to make the ball stationary, so that it keeps still, or moves very little, when you punch it, every punch, no mat ter at what rate you punch it, will catch the ball and have its full effect upon it. In somewhat the same way our large iron mass is kept as station ary as possible, by the damping cylinders, while each earth-wave has its full effect upon it. This effect is received by the arrangement of levers above the mass, and magnified enormously, which magnified effect is traced by the recording stylus or pen--a tiny platinum pin-on the smoked re cording roll of paper, Waves coming in a N or S direction are recorded on one of the rolls; those in an E or W direction are recorded on the other, while waves coming in any other direction are recorded on both.

The Vertical Wiechert Seismograph is a Lever-Pendulum, consisting of an iron mass of 160lbs. weight at the end of an arm (under the wooden temperature-insulation box), and a spiral spring (enclosed in the box) be tween the weight and the fulcrum, the weight and the spring keeping the arm of the lever in equilibrium. Hence this pendulum can move only up and down, only by the vertical part of the earth-waves. The effect, as before, is highly magnified and recorded by the stylus. The damping (drum-like) arrangement in this instrument is seen at the left-hand back corner of the table. The temperature-insulation box is simply a double-walled wooden jacket packed with carbon, to protect the spiral, as well as a zinc-steel grid iron compensation, from change of temperature. One of the greatest diffi culties with these instruments is keeping the instrument room at the same temperature always. For this reason the brick building is not yet nearly completed, as it will have to be covered by a thick layer of protecting material, which will finally have to be covered by a proper roofing. Again, scientifically inclined and generously disposed friends, please note!

To lessen any disturbance from the room itself (visitors, etc.) the floor of the building is covered with sand to the depth of a few inches, and in the case of the Horizontal, an air gap to the depth of a few feet sepa rates the instrument from the surrounding floor.

The records, which are changed every twenty-four hours, are traced on specially-prepared smoked paper, and can be fixed at once with a suitable varnish. On the instruments, the records are stretched by drums which, by a very nice clock-work device (c.f, weight and escapement) are rotated once every hour, and moved to the right at the same time. Fur thermore, by an ingenious electro-magnetic contrivance connected with a Wiechert contact-clock (seen with the Vertical Seismograph), the hours and minutes are accurately recorded on the earthquake tracing itself, and not at the side. Consequently, the exact second almost at which a distur bance begins is known. The rate of tracing is about fourteen millimetres per minute for the Horizontal, and ten millimetres per minute for the Vertical Seismograph.

To the uninitiated, at least, the results in the matter of records are really marvellous. They are worth the trouble they entail, and they do en tail lots of trouble. So far, there have been records of at least four con siderable earthquakes (one of which has been already identified), as well as eight or nine smaller ones. Some of these have probably been subma rine, and can be localised when reports come in from other distant Obser vatories. There is one more point to be treated in this rather crude explanation, and it will explain the last sentence. How is the distance of the earthquake ascertained? Well, in a large seismic disturbance, if situ ated at a considerable distance, preliminary earth tremors or short waves precede the long earthquake-waves. The distance of the centre of the dis turbance (which usually lasts for an hour or two) can be calculated from the time elapsing between the first preliminary tremors, and the beginn ing of the long waves. Consequently when three Observatories sufficiently distant and suitably situated calculate the distance of a particular shock, say, in mid-ocean, the actual centre can be found by simple geometry.

I have tried to give a simple, straightforward, unscientific explanation of the instruments, without going into more detail than was absolutely necessary. In fact, it would be unwise to go into much detail, for, if I did, I should probably become helpless very soon, and should require a kind and helping hand from Father Pigot to extricate me. But the calculations in volved are terrific—a fact that will appear plausible when we say (I have it on Father Pigot's word) that the pressure of the stylus on the record, equivalent to a weight of one milligram, must be allowed for in the reductions of the observations.

Letters from Our Past

Father Edward Pigot SJ

China

Father Pigot SJ, whom our past students of late years will remember, writes from the Shanghai district: to somewhat the same purport :

“Oh, if we only had a few thorough-going Irish priests here, how many more poor Chinese could be received into the Church! In some parts, as in the North, and in Father Perrin's section, one priest more would nean the certain conversion of hundreds and hundreds of Pagans. But Father Superior is at the end of his tether and can not send any more men just now; for the Christian villages around here cannot be left without their missionaries”.

In another letter, dated October of present year, Father Pigott writes :

“Here in our mission, as indeed throughout nearly the whale of China, things are quiet enough : how long it will last I do not know, The Boxers have lately broken out again in the south-west. We had many deaths this past year among our missionaries, and are badly in want of men, especially in the newly opened up districts in the north and in parts of the west of our mission. I send you the lately published yearly “Resumé” of the Kiang Nan. It is, above all, in the Sin-tchcou-fou (Western) Section that the greatest movement of conversion has taken place recently among the people whole villages sometimes asking to be received for instruction for baptism. But how receive them? The means are wanting - above all men. If Fathe
