In truth a general distrust prevailed throughout the party concerning Lisa and his intentions.

They considered him artful and slippery, and secretly anxious for the failure of their expedition.

There being now nothing more to be apprehended from the Sioux, they suspected that Lisa would take advantage of his twenty-oared barge to leave them and get first among the Arickaras.

As he had traded with those people and possessed great influence over them, it was feared he might make use of it to impede the business of Mr.Hunt and his party.

It was resolved, therefore, to keep a sharp look-out upon his movements; and M'Lellan swore that if he saw the least sign of treachery on his part, he would instantly put his old threat into execution.
Notwithstanding these secret jealousies and heart-burnings, the two parties maintained an outward appearance of civility, and for two days continued forward in company with some degree of harmony.
