A diversion in the lives of Mrs. Jaggar and myself was an invitation in 1936 from the Royal Society of London, to go to Montserrat in the West Indies where for three years they had been having bad earthquakes. Sir Gerald Lenox-Conyngham, whom we had met at the Japan congress, wrote me asking for my help because Montserrat’s dormant hot volcano was making excessive hydrogen sulfide gas at its two solfataras. The smell sickened and alarmed the inhabitants of the port of Plymouth, and the gas was blackening the paint of white steamships. The earthquakes had come in spasms culminating in big damage to masonry from 1934 onward. Perret had flown over from Martinique and tried to help by applying sound theories to prediction of seasonal tidal controls of the volcano, but he was scoffed at as a voodoo soothsayer by a British Navy captain. The scientific commission appointed was Dr. C. F. Powell of Bristol, now Nobel Prize physicist, and Dr. A. G. MacGregor of the Geological Survey, besides Dr. Lenox-Conyngham, formerly Director of the Geodetic Survey of India. Dr. Powell used adaptations of my shock recorder, both horizontal and vertical, built by the Kew Observatory. Designs had been obtained from instruments I sent to Dr. Marsden in New Zealand, after the Napier earthquake. When I received the invitation to go to Montserrat, I packed up such instruments as I could find, and telephoned Mrs. Jaggar in Honolulu to be ready to go with me to Los Angeles the following Saturday. She was always ready to act as secretary on a new adventure, and with much bustle and scramble we packed her things. Later I joined her at the steamer, a Danish freighter which was to take us through the Canal to the Caribbean. Boarding as we did on such short notice, we were given a steward’s room in the bowels of the ship; but we had the run of the first cabin. It was a delightful trip through Panama and Jamaica, both of which I was happy to see again, twenty-six years after my 1910 experience with the canal engineers. Great changes had been wrought, and it was a thrill to see the ship pulled through step-up after step-up of canal locks, by the “iron mules” of that marvelous machinery. We left the delightful freighter people at Charlotte Amalie in the Virgin Islands where we stayed at Blue Beard’s Castle. After a wait of some days, we got a small Dutch island freighter to go to Montserrat. We stopped at St. Martin, an astonishing place, French at one end and Dutch at the other, with practically no custom house to mark the boundary, though the wines and the language changed in the middle of the island.
