(b). In the St. Lawrence River north of the mouth of Rivière Ouelle. Chimneys thrown down and walls damaged. The earthquake was felt from Hamilton, Ont., in the west, to New Brunswick in the east, and southward in the United States as far as Newark, N.J. over an area of 700,000 square miles.

"The buildings situated on each side of our river (Rivière Ouelle) suffered in a general way. One chimney on the home of E. Chas. Tetu, two on the home of M. C. Casgrain, one on the home of M. Frenette, one on the home of Auguste Casgrain, one on the home of Madam Frs. Casgrain and on the homes of a dozen other persons were thrown down. The cross of our church and the weathervane surmounting it are now on the ground; the walls of our fine church are cracked. The shocks were frightening; the first, the most violent, began at 6:15 and lasted four minutes and forty seconds, very violent for ten seconds and gradually weakening; a weaker shock at 6:20 lasted three or four seconds, and the third began at 6:30 and lasted two or three seconds; but like the first it was a staccato jolting that made the furniture dance and unhooked pictures, clocks, etc." D2 quoting from a Quebec newspaper.
