The scene of destruction, which has often been mentioned, namely, the whitening bones of buffaloes and stags, recurs everywhere in the prairie, and the great dogs of the fort frequently seek for such animal remains. Between the hills, there are, sometimes, in the ravines, little thickets of oak, ash, negundo maple, elm, bird-cherry, and some others, in which many kinds of birds, particularly the starling, blackbird, &c., build their nests. The king-bird and the red thrush are likewise found. Of mammalia, besides those in the river, namely, the beaver, the otter, and the muskrat, there are, about Fort Union, in the prairie, great numbers of the pretty little squirrel, the skin of which is marked with long stripes, and regular spots between them (Spermophilus Hoodii, Sab.), which have been represented by Richardson and Cuvier. The Anglo-Americans of these parts call it the ground squirrel; and the Canadians, l'écureuil Suisse. From its figure and agility, it is a genuine squirrel, and, therefore, rather different from the true marmot arctomys. The burrows, in which these animals live, are often carried to a great extent underground. The entrance is not much larger than a mouse hole, and has no mound of earth thrown up, like those of the prairie dogs. Besides these, there are several kinds of mice, particularly Mus leucopus. The flat hills of the goffer are likewise seen; this is a kind of large sand rat, living underground, of which I did not obtain a specimen.

Not far above and below the fort there were woods on the banks of the Missouri, consisting of poplars, willows, ash, elm, negundo maple, &c., with a thick underwood of hazel, roses, which were now in flower, and dog-berry, rendered almost impassable by blackberry bushes and the burdock (Xanthium strumarium), the thorny fruit of which stuck to the clothes. In these thickets, where we collected many plants, the mosquitos were extremely troublesome. In such places we frequently heard the deep base note of the frogs; and in those places which were not damp, there were patches of two kinds of solidago; likewise Gaura coccinea (Pursh.), and Cristaria coccinea, two extremely beautiful plants; and, on the banks of the river, the white-flowering Bartonia ornata (Pursh.), and the Helianthus petiolaris (Nutt.), which were everywhere in flower, &c. &c.

193 In the forest, a pretty small mouse was frequent, as well as the large wood rat, already mentioned. Of birds, there are some species of woodpeckers, the Carolina pigeon, numerous blackbirds (Quiscalus ferrugineus), thrushes, several smaller birds, the beautiful bluefinch, first described by Say, the American fly-catcher, and several others. The whip-poor-will is not found so high up the Missouri. The river does not abound in fish; it produces, however, two species of cat-fish, and soft shell turtles, but which are not often caught.

The climate about Fort Union is very changeable. We had often 76° Fahrenheit, and storms of thunder and lightning alternating with heavy rains. Other days in the month of June were cold, the thermometer falling to 56°. Winds prevail here the greater part of the year, and therefore the temperature is usually dry. The weather, while we were there, was uncommonly rainy. Spring is generally the wettest season; the summer is dry; autumn the finest time of the year; the winter is severe, and often of long continuance. The snow is often three, four, or six feet deep in many places, and then dog sledges are used, and the Indians wear snow shoes. The winter of 1831-1832 had been remarkably mild in these parts. The Missouri had scarcely been frozen for three days together; but the spring, however, set in very late. On the 30th of May, 1832, the forests were still without verdure; and there was, in that month, such dreadful weather, that an Indian was frozen to death in the prairie: a snow storm overtook him and a girl, who escaped with one of her feet frozen. In general, however, the climate is said to be very healthy. There are no endemic disorders, and the fine water of the Missouri, which, notwithstanding the sand mixed with it, is light and cold, does not a little contribute to make the inhabitants attain an advanced age. There are no physicians here, and the people affirm they have no need of them. Persons, whom we questioned on the subject, said, "We don't want doctors; we have no diseases." In the preceding spring, however, there had been more sickness than usual on the Missouri, and at the time of our visit, the approach of the cholera was feared. Colds are, probably, the most frequent complaints, the changes in the temperature being sudden, the dwellings slight and ill built, and the people exposing themselves without any precaution.

Fort Union is built in the territory of the Assiniboins, of whom a certain number generally live there. At this time they had left, because the herds of buffaloes were gone to a distant part of the country. The Assiniboins are real Dacotas, or Sioux, and form a branch which separated from the rest a considerable time ago, in consequence of a quarrel among them. They still call themselves by that name, though they seem generally to pronounce it Nacota. They parted from the rest of the tribe, after a battle which they had with each other on Devil's Lake, and removed further to the north. The tribe is said to consist of 28,000 souls, of whom 7,000 are warriors. They live in 3,000 tents; the territory which they claim as theirs, is between the Missouri and the Saskatschawan, bounded by lake Winipick on the north, extending, on the east, to Assiniboin River, and, on the west, to Milk River. The English and Americans sometimes 194 call them Stone Indians, which, however, properly speaking, is the name of only one branch.

The Assiniboins are divided into the following branches or bands:

1. Itscheabiné (les gens des filles).

2. Jatonabinè (les gens des roches). The Stone Indians of the English. Captain Franklin, in his first journey to the Frozen Ocean, speaks of these Indians, and observes that they are little to be depended upon.[363] He says that they call themselves Eascab, a name with which, however, I have not met.

3. Otopachgnato (les gens du large).

4. Otaopabinè (les gens des canots).
