Walls of verdure stretched on left and right. Now, aloft in the lonely air rose the cliffs of Belceil, and now, before them, framed in circling forests, the Basin of Chambly spread its tranquil mirror, glittering in the sun. The shallop outsailed the canoes. Champlain, leaving his allies behind, crossed the basin and tried to pursue his course; but, as he listened in the stillness, the unwelcome noise of rapids reached his ear, and, by glimpses through the dark foliage of the Islets of St. John he could see the gleam of snowy foam and the flash of hurrying waters. Leaving the boat by the shore in charge of four men, he went with Marais, La Routte, and five others, to explore the wild before him. They pushed their way through the damps and shadows of the wood, through thickets and tangled vines, over mossy rocks and mouldering logs. Still the hoarse surging of the rapids followed them; and when, parting the screen of foliage, they looked out upon the river, they saw it thick set with rocks where, plunging over ledges, gurgling under drift-logs, darting along clefts, and boiling in chasms, the angry waters filled the solitude with monotonous ravings. Champlain retraced his steps. He had learned the value of an Indian's word. His allies had promised him that his boat could pass unobstructed throughout the whole journey. "It afflicted me," he says, "and troubled me exceedingly to be obliged to return without having seen so great a lake, full of fair islands and bordered with the fine countries which they had described to me." When he reached the boat, he found the whole savage crew gathered at the spot. He mildly rebuked their bad faith, but added, that, though they had deceived him, he, as far as might be, would fulfil his pledge. To this end, he directed Marais, with the boat and the greater part of the men, to return to Quebec, while he, with two who offered to follow him, should proceed in the Indian canoes. The warriors lifted their canoes from the water, and bore them on their shoulders half a league through the forest to the smoother stream above. Here the chiefs made a muster of their forces, counting twenty-four canoes and sixty warriors. All embarked again, and advanced once more, by marsh, meadow, forest, and scattered islands,--then full of game, for it was an uninhabited land, the war-path and battleground of hostile tribes. The warriors observed a certain system in their advance. Some were in front as a vanguard; others formed the main body; while an equal number were in the forests on the flanks and rear, hunting for the subsistence of the whole; for, though they had a provision of parched maize pounded into meal, they kept it for use when, from the vicinity of the enemy, hunting should become impossible.
