The voyagers were now out of range of Crows and Black-feet; but they were approaching the country of the Rees, or Arickaras; a tribe no less dangerous; and who were, generally, hostile to small parties.
In passing through their country, Wyeth laid by all day, and drifted quietly down the river at night. In this way he passed on, until he supposed himself safely through the region of danger; when he resumed his voyage in the open day.
