Saba is a startling extinct volcano rising as a steep rocky cone directly from the water, with no harbor but a stop opposite a gully that leads up to the crater. After landing in small boats, we climbed up the gulch to the settlement, a picturesque place, with masonry houses and many flowers, where the government is Dutch but all talk English, and its history goes back to the buccaneers. The village is on a flat in the lowest part of a cup crater, the top of our climb, but the name of the settlement is The Bottoms. Our little ship joined the main line of the leeward volcanoes at St. Kitts, where we made connections for Antigua and Montserrat. In Montserrat we stayed with Miss Gillie at the Rainbow House and joined the Englishman Powell and the Scot MacGregor. I met Perret at Antigua, and we compared notes on the similarity of the earthquakes and the rotten-egg smell (sulfuretted hydrogen) at Montserrat to the eruptions of Pelée in Martinique, where these phenomena were followed by explosions and lava. The Montserrat authorities justly feared what was coming. Perret had for two years kept track of events at Montserrat in relation to equinox and solstice. He had built a hut there at the dangerous solfatara near town, had made an instrument shelter with a thermograph, and on a pedestal close to a nearby residence had set up an ingenious earthquake accumulator, which had recorded at the end of twenty-four hours the total expenditure of seismic energy in each direction. As there were hundreds of strong shocks, the instruments recorded total seismic energy per day and its dominant direction. I found that Powell had set up my shock recorders among volunteers on the island, and a seismograph at the agricultural station. A new form of the Jaggar shock recorder had the weight attached to horizontal flat springs so as to oscillate up and down. I was especially pleased with the earthquake records kept by a Mr. English living in the countryside. Assisted by his wife, he had carefully listed the times and intensities of hundreds of shocks, with notes on important events. Much help was furnished by the Agricultural Experiment Station, which provided an assistant to take us to many geologic places and to the second solfatara, consisting of hot springs and sulfur in a southern valley of the volcano. The volcano of Montserrat is at the south end of the island, while the northern part consists of older hills. The summit crater is a remote and inaccessible forested area among peaks. The volcano is much like Pelée in size and appearance.
