recover, they left him. Others passing that way, some years after, found his bones a short distance from where he had been left. From this circumstance, these hills have been called, since that time, after the name of that unfortunate adventurer. In the extreme point of these hills, near the River, and about fifty feet above highwater, are found great numbers of semi-petrified Turtles, from one to two feet across, imbedded in the sand, and many of them entirely perfect. There are no animals of this kind now in the Platte River, or elsewhere in the country, for several hundred miles around.
We continued up the North Fork, and on the 13th came to Lauramie Fork, opposite Fort Lauramie. Finding it full, we were obliged to ferry, and for this purpose we procured two small boats from the Forts, lashed them together, and covered them with a platform made of wagon beds, which we had taken to pieces for the purpose. Upon this platform, we placed the loaded wagons by hand, and although the stream was very rapid, all succeeded in crossing without much difficulty. A few hours after we crossed, a hail storm came up from the North West; before which, our animals ran for several miles, over the hills. Fort Lauramie belongs to the American Fur Company, and is built for a protection against the Indians. The occupants of the Fort, who have been long there, being mostly French and having married wives of the Sioux, do not now apprehend any danger. The Fort is built of Dobies, (unburnt bricks.) A wall of six feet in thickness and fifteen in height, encloses an area of one hundred and fifty feet square. Within and around the wall, are the buildings, constructed of the same material. These are a Trading House, Ware House for storing goods and skins, Shops and Dwellings for the Traders and Men. In the centre, is a large open area. A portion of the enclosed space is cut off by a partition wall, forming a carell, (enclosure,) for the animals belonging to the Fort. About one mile below Fort Laurimie, is Fort Platte; which is built of the same materials and in the same manner, and belongs to a private Trading Company.
On the morning of the 16th, we left the Forts, and after having traveled ten miles, we came to the Black Hills, and encamped at a large Spring, the water of which was quite warm. The road through these hills is, of necessity, very circuitous; winding about as it must, to avoid the steeps, ravines, and rocks. They are very barren and some of them
