Satisfied from this view that it was useless to follow its course, either by land or water, they had given up all further investigation.
These concurring reports determined Mr.Hunt to abandon Mad River, and seek some more navigable stream.

This determination was concurred in by all his associates excepting Mr.Miller, who had become impatient of the fatigue of land travel, and was for immediate embarkation at all hazards.

This gentleman had been in a gloomy and irritated state of mind for some time past, being troubled with a bodily malady that rendered travelling on horseback extremely irksome to him, and being, moreover, discontented with having a smaller share in the expedition than his comrades.

His unreasonable objections to a further march by land were overruled, and the party prepared to decamp.
Robinson, Hoback, and Rezner, the three hunters who had hitherto served as guides among the mountains, now stepped forward, and advised Mr.Hunt to make for the post established during the preceding year by Mr.Henry, of the Missouri Fur Company.

They had been with Mr.Henry, and, as far as they could judge by the neighboring landmarks, his post could not be very far off.
