In the evening they encamped on a branch of Big River.
They were now out of the tract of country infested by the Sioux, and had advanced such a distance into the interior that Mr.Hunt no longer felt apprehensive of the desertion of any of his men.

He was doomed, however, to experience new cause of anxiety.

As he was seated in his tent after nightfall, one of the men came to him privately, and informed him that there was mischief brewing in the camp.

Edward Rose, the interpreter, whose sinister looks we have already mentioned, was denounced by this secret informer as a designing, treacherous scoundrel, who was tampering with the fidelity of certain of the men, and instigating them to a flagrant piece of treason.

In the course of a few days they would arrive at the mountainous district infested by the Upsarokas or Crows, the tribe among which Rose was to officiate as interpreter.
