nearly eight o'clock
It was out of the question so long as the Sioux was his companion , but if he should leave him alone , even for a short time , the youth was resolved to make the attempt . These and similar thoughts were chasing one another through his brain when he fell asleep . He was very tired from his long tramp and did not open his eyes until the faint light of morning penetrated his prison . He had not forgotten to wind his watch , and when he looked at it he saw to his astonishment that it was nearly eight o'clock . He had slept for more than ten hours . The next cause of his surprise was to find he was alone . Motoza had left while he was asleep , though how long previous it was impossible to guess .
