the narrow valley of the Platte, which is from five to ten miles wide, are little else than huge piles of sand. The valley itself is quite sandy; but it nevertheless produces a rich grass, which our animals were very fond of. It is also covered, in many places, with the Prickly Pear, the thorns of which frequently get into the feet of the loose cattle and produce lameness. The River is from one to three miles in width, and the bed of the channel is entirely of quicksand. When we came to it, it was quite full, and the water was every where running level with its banks, but seldom overflowing them, and was running with a strong, even current. There is, in many places along the Platte, a kind of salt, with which the ground, in spots, is covered; and the water in the River is slightly impregnated. In some of the sloughs and pools, back from the River, the water is very strong. We found but little wood here, and none except immediately on the River. We were frequently unable to procure it, and were compelled, sometimes, to make a strange substitute in the excrement of the Buffalo, in order to do our cooking. The varieties of timber are few; the principal kind being what is commonly called Cotton Wood. We saw great numbers of Antelopes, as we passed up the River; but they were so wild, and the valley was so level, that it was difficult to approach them. We also saw a singular little animal, which has been called the Prairie Dog. Its size, shape and color, are very much the same as the large Wharf rat, and its barking resembles that of the common Gray Squirrel. They burrow in the ground and live in villages, frequently of several hundreds. There is a small Owl that sometimes lives in the same hole with the Dog.
As we were now coming into the game country, and expecting every day to see the plains covered with herds of Buffalo; we made up a hunting party, (having previously joined one of the emigrating parties,) of 20 men, and pro-
