“The same day about eight o’clock in the evening, there came a second shock, equally violent as the first, and within the space of half an hour, there were two others. The next day about three hours from the morning, there was a violent shock, which lasted a long time, and the next night counted some thirty-two shocks, of which many were violent. Nor did the trembling of the earth cease until the July following. Many trees were torn up, and the outlines of the mountains appeared to be much changed. Many springs and small streams were dried up; in others the waters became sulphurous, and the channels in which some had run were so altered as to be unrecognizable. Half way between Tadousac and Quebec two hills were thrown down and formed a point of land which extended half a quarter of a league into the St. Lawrence River. The island Aux Coudres became larger than it was before, and the channel of the St. Lawrence was greatly changed.” This is, perhaps, as severe a shock as has been felt in this country; but though the shock extended southward to Pennsylvania, its chief energy was centered in a narrow strip on the St. Lawrence, giving our Canadian neighbors the lion’s share of the fright. Other light shocks were noticed in New England in 1665, 1668, 1669, 1670, 1705, and 1720. October 29, 1727, another severe earthquake was experienced about 10:40 P.M. It seems to have had Southern New Hampshire as its focus, extending thence to the Delaware and Kennebec rivers. Its approach was heralded by a subdued roar from the northwest, which, as it drew nearer, “was thought to be the roar of a blazing chimney near at hand, and at last was likened to the rattling of carriages driven fiercely over pavements. In about half a minute from the time the noise was first heard, the earthquake was felt. It was observed by those who were abroad that, as the shake passed under them, the surface of the earth rose and sank.” Houses trembled and rocked, as though about to fall to pieces. Movables were dashed about with a fearful clatter. Crockery was smashed; stone walls and chimneys thrown down. At Newbury, ashes and sulphur were cast forth from the earth, and also volumes of sand. Sulphuretted hydrogen seems to have been present in large quantities: also chemicals readily decomposed by warmth and moisture.
