Stunned by the suddenness of the calamity, and utterly unable to comprehend it, some thought that a fire had broken out, and ran for help; others that the Indians had made an incursion, and flew to arms, but soon the momentarily increasing violence of the shocks led to the universal conclusion that the end of the world had come. The consternation both of French and Indians can hardly be imagined. The general impulse was to hasten to the churches, and prepare to appear before the judgment seat of God, and truly wonderful were the conversions which ensued: a missioner afterwards told the Mother of the Incarnation, that he had himself heard eight hundred general confessions at that period of panic. After a half- an-hour, the oscillations of the earth became fainter, without however wholly ceasing, but about eight o'clock there was a second shock so severe, that the Sisters who were at the time standing in their stalls chanting the Office, were all thrown to the ground. The earthquake continued at intervals for a full year, the first five months in its original force, the remainder of the period with less violence. Sometimes the motion of the earth was like the pitching of a large vessel dragging heavily at its anchors; at others, it was hurried and irregular, creating sudden, and occasionally very violent jerks, but in general it was merely tremulous. During all that time, men lived in constant dread of immediate death, and actually withered away from fear. The Lent was spent by the Sisters in redoubled austerities, and increasing prayers to appease the anger of God. "Every evening," the Mother of the Incarnation wrote to her son, "we disposed ourselves to be engulphed in the yawning earth before morning, and when a new day dawned, we prepared to stand in God's presence before its close."
After the fearful convulsion of nature had at last ceased, its terrible traces were but too distinctly visible over the entire country. In some parts, mountains had disappeared, swallowed by the gaping earth, or precipitated into adjacent rivers, leaving vast chasms in the places which they had occupied; in others, new ones had suddenly arisen. Lakes were to be seen in localities previously occupied by forests. A new island had sprung up in the St. Lawrence; volcanic craters had burst open; some rivers had been turned from, their course, others totally lost. A rocky mountainous district of three hundred miles in extent, had been levelled as if some mighty harrow had passed over it. The earthquake seems to have extended more than six hundred miles in length, and about three hundred in breadth; thus one hundred and eighty thousand square miles of land were convulsed at the same moment. A most singular circumstance connected with the awful visitation is, that not a single individual perished, or was even slightly injured.
