"As for the rest, we have remarked that, though this earthquake continued almost without intermission, yet it was not always of an equal violence. Sometimes it was like the pitching of a large vessel which dragged heavily at her anchors, and it was this motion which occasioned many to have a giddiness in their heads and a qualmishness in their stomachs. At other times the motion was hurried and irregular, creating sudden jerks, some of which were extremely violent; but the most common was a slight tremulous motion, which occurred frequently with little noise. Many of the French inhabitants and Indians, who were eye-witnesses to the scene, state that, a great way up the river of Trois Rivières, about eighteen miles below Quebec, the hills which bordered the river on either side, and which were of a prodigious height, were torn from their foundations, and plunged into the river, causing it to change its course, and spread itself over a large tract of land recently cleared; the broken earth mixed with the waters, and for several months changed the color of the great River St. Lawrence, into which that of Trois Rivières disembogues itself. In the course of this violent convulsion of nature, lakes appeared where none ever existed before; mountains were overthrown, swallowed up by the gaping, or precipitated into adjacent rivers, leaving in their places frightful chasms or level plains; falls and rapids were changed into gentle streams, and gentle streams into falls and rapids. Rivers in many parts of the country sought other beds, or totally disappeared. The earth and the mountains were entirely split and rent in innumerable places, creating chasms and precipices, whose depths have never yet been ascertained. Such devastation was also occasioned in the woods, that more than a thousand acres in our neighborhood were completely overturned; and where, but a short time before, nothing met the eye but one immense forest of trees, now were to be seen extensive cleared lands, apparently cut up by the plow.
