They at length gave up the search, and he began to rejoice in his escape, when the idea presented itself that they might set the raft on fire.

Here was a new source of horrible apprehension, in which he remained until nightfall.

Fortunately the idea did not suggest itself to the Indians.
As soon as it was dark, finding by the silence around that his pursuers had departed, Colter dived again and came up beyond the raft.

He then swam silently down the river for a considerable distance, when he landed, and kept on all night, to get as far as possible from this dangerous neighborhood.
By daybreak he had gained sufficient distance to relieve him from the terrors of his savage foes; but now new sources of inquietude presented themselves.

He was naked and alone, in the midst of an unbounded wilderness; his only chance was to reach a trading post of the Missouri Company, situated on a branch of the Yellowstone River.
