126 Mackenzie’s Voyages or maimed by large rocks which were continually rolling from the banks. A reconnaissance of several hours through the woods brought them out on the river where the mountain spur abuts on the stream. The channel was about a hundred yards broad, and from this point, looking downstream, they saw the river contracted to fifty yards and rushing with great velocity between perpendicular rocks. Mackenzie waited here in great anxiety for the arrival of the canoe. At last he sent Mackay down in search of it, while he and the others continued a mile and a half farther up, where the river flowed between precipices three hundred feet high in a succession of rapids and cascades. Returning to the last point, the canoe was seen being portaged over a rocky projection below. It had been broken but the men had repaired it, and now with the line they were able to ascend to where Macken- zie had been. An inviting beach led them to camp for the night, and while resting by their fires of driftwood they were interested by the appearance of several elk feeding on the edge of the opposite precipice three hundred feet above them. The explorer sent a man and an Indian ahead next day to reconnoitre. The voyageur reported that it would be im- practicable to pass several points, particularly thosew here the undercut cliffs projected. ‘he canoe was again broken next day in hauling it over a difficult place and Mackenzie risked his life in jumping to a place of vantage in order that he might assist the others to the same point without danger to them. When the poles failed them they had recourse to the towing-line, a highly dangerous proceeding as the men who held the line were high up on the cliffs; and had frequently to pass it around projecting rocks and trees that overhung the cliffs, while the men below had all they could do to prevent the current from swinging them in and out
