The buffalo would scarcely move out of the path at all, and the bulls sometimes, even when unmolested, threatened to assail the hunters.

Once, on the return voyage, when Clark was descending the Yellowstone River, a vast herd of buffalo, swimming and wading, plowed its way across the stream where it was a mile broad, in a column so thick that the explorers had to draw up on shore and wait for an hour, until it passed by, before continuing their journey.

Two or three times the expedition was thus brought to a halt; and as the buffalo were so plentiful, and so easy to kill, and as their flesh was very good, they were the mainstay for the explorers' table.

Both going and returning this wonderful hunting country was a place of plenty.
