The furs collected by Jackson's company were cached on the Wind River; and the cold still being very severe, and game scarce, the two remaining leaders, Smith and Jackson, set out on the first of January with the whole camp, for the buffalo country, on the Powder River, a distance of about one hundred and fifty miles. "Times were hard in camp," when mountains had to be crossed in the depth of winter.
The animals had to be subsisted on the bark of the sweet cotton-wood, which grows along the streams and in the valleys on the east side of the Rocky Mountains, but is nowhere to be found west of that range. This way of providing for his horses and mules involved no trifling amount of labor, when each man had to furnish food for several of them. To collect this bark, the men carried the smooth limbs of the cotton-wood to camp, where, beside the camp-fire, they shaved off the sweet, green bark with a hunting-knife transformed into a drawing-knife by fastening a piece of wood to its point; or, in case the cotton-wood was not convenient, the bark was peeled off, and carried to camp in a blanket. So nutritious is it, that animals fatten upon it quite as well as upon oats.
In the large cotton-wood bottoms on the Yellowstone River, it sometimes became necessary to station a double guard to keep the buffalo out of camp, so numerous were they, when the severity of the cold drove them from the prairies to these cotton-wood thickets for subsistence. It
