The Fort gates being closed against them, they demanded admittance on the plea of wishing to trade.
"What would you buy ?" asked the commandant.
" Tobacco."
" What have you brought to pay for it ?"
" A white man."
" A white man ?" exclaimed the former; " at what price?"
" Oh, he is not worth much. A plug of tobacco is his full value!" continued the warriors.
The commandant now began to understand the joke; and, on recognizing the prisoner as an employee of the other Fort, he told them they might possibly find a market for him at the next post, but for his own part he was not disposed to purchase.
The Indians then paraded around the Fort, and, after saluting its inmates with three deafening whoops, proceeded at full charge towards Fort Platte.
When arrived, having prostrated two scaffolds of dead Sioux by the way, they informed the person in charge, that they had brought back one of his men, and claimed from him a plug of tobacco for their trouble. The circumstances attending this request were of so comical a nature, the commandant felt disposed to humor the joke, and gave the tobacco, upon which they immediately left in pursuit of their enemies.
Having remained prisoners to the hospitality of these Indians for two days and a half, we were at length permitted again to resume our journey.
Following the creek downwards for the two days next succeeding, and then bearing to the left, after a ride of some twelve miles, we struck Laramie river at a point which presented broad bottoms upon each side with an abundance of timber; here we remained encamped till the subsequent day. In journeying thus far, we passed over a sufficient extent of this broad expanse to give a general description of it, from personal observation coupled with information derived from others more experienced.
The Plains of Laramie are bounded north and east by the Black Hills, south by a ridge of naked elevations, (composed of soft, arenaceous rock and terrene limestone, embedded in marl and white clay, sterile and almost entirely destitute of vegetation,) and west by the Medicine Bow Mountains.
This section includes an area one hundred and sixty miles long by seventy broad.
The northern portion of it is a high plateau, almost destitute of springs or streams of water, having a mixed soil of clay and sand, producing the grass and other peculiarities incident to the grand prairies. Westerly, it is composed of red sand and gravel, tolerably fertile and abundant in rocky fragments. The southern portion is watered by a number of streams that rise in the Medicine Bow Mountains and flow eastward; some of them pouring their waters into Laramie river, and others losing themselves in the sand.
Towards the southwestern extremity, at the base of a lofty, isolated mountain, is a salt lake of considerable dimensions. Several other lakes are also found
