nating at the bottom in an abrupt precipice over the stream. This was the east side of the fall. At length, after a quarter of a mile, I got down to still water, and, on looking up through the winding gorge, I could just see to the foot of the fall which I had before examined; while from the opposite side of the stream, here much contracted, rose a perpendicular wall, I will not venture to say how many hundred feet, but only that it was the highest perpendicular wall of bare rock that I ever saw. In front of me tumbled in from the summit of the cliff a tributary stream, making a beautiful cascade, which was a remarkable fall in itself, and there was a cleft in this precipice, apparently four or five feet wide, perfectly straight up and down from top to bottom, which, from its cavernous depth and darkness, appeared merely as a black streak. This precipice is not sloped, nor is the material soft and crumbling slate as at Montmorenci, but it rises perfectly perpendicular, like the side of a mountain fortress, and is cracked into vast cubical masses of gray and black rock shining with moisture, as if it were the ruin of an ancient wall built by Titans. Birches, spruces, mountain-ashes with their bright red berries, arbor-vitæs, white pines, alders, &c, overhung this chasm on the very verge of the cliff and in the crevices, and here and there were buttresses of rock supporting trees part way down, yet so as to enhance, not injure, the effect of the bare rock.

This was the limit of our walk down the St. Lawrence. Early in the afternoon we began to retrace our
