For example, when they reached a difficult shoal on the Yellowstone River, they named that Buffalo Shoal because they found a buffalo on it; and Buffalo Shoal it remains unto this day.

In like manner, when they reached a dangerous rapid, twenty miles below that point, they saw a bear standing on a rock in the stream; and Bear Rapid the place was and is named.

Bear and buffalo were pretty numerous all the way along that part of the river which they navigated in July.

They had now rejoined the boats, and on the last day of July, when camped at a point two miles above Wolf Rapid (so called from seeing a wolf there), the buffalo were continually prowling about the camp at night, exciting much alarm lest they should trample on the boats and ruin them.

In those days, buffalo were so numerous that they were a nuisance to travellers; and they were so free from fear of man that they were too familiar with the camps and equipage.
