As they were hunting on the river they saw a low ground covered with thick brushwood, where from the tracks along shore they thought a bear had probably taken refuge.
They therefore landed, without making a noise, and climbed a tree about twenty feet above the ground.

Having fixed themselves securely, they raised a loud shout, and a bear instantly rushed toward them.

These animals never climb, and therefore when he came to the tree and stopped to look at them, Drewyer shot him in the head.

He proved to be the largest we had yet seen; his nose appeared to be like that of a common ox; his fore feet measured nine inches across; the hind feet were seven inches wide and eleven and three quarters long, exclusive of the talons.
One of these animals came within thirty yards of the camp last night, and carried off some buffalo-meat which we had placed on a pole." The party were very much annoyed here by the grizzlies which infested their camp at night.

Their faithful dog always gave warning of the approach of one of these monsters; but the men were obliged to sleep with their guns by their side, ready to repel the enemy at a moment's notice.
Captain Clark finally broke up the camp on Portage Creek, June 28, having deposited in his cache whatever could be left behind without inconvenience.
