The country of the Canadian above that last considered, or that portion of it west of the assumed meridian, appears to be possessed of a soil somewhat richer than the more northerly parts of the section, but exhibits no indications of extraordinary fecundity in any part of it. Proceeding westward, a very gradual change is observable in the apparent fertility of the soil, the surface becoming more sandy and sterile, and the vegetation less vigorous and luxuriant. The bottoms appear to be composed, in many places, almost exclusively of loose sand, exhibiting but few signs of vegetation. Knobs and drifts of sand, driven from the bed of the river by the violence of the wind, are piled in profusion along the margin of the river throughout the greater part of its length. It is remarkable, that these drifts are in many instances covered with grape vines of a scrubby appearance, bearing fruit in the greatest abundance and perfection. The vines grow to various heights, from eighteen inches to four feet, unaccompanied, in some instances, by any other vegetable, and bear a grape of a dark purple or black colour, of a delicious flavour, and of the size of a large pea or common gooseberry.

The waters of this section, almost in every part of it, appear to hold in solution a greater or less proportion of common salt and sulphate of magnesia, which, in many instances, render them too brackish or bitter for use. Saline and nitrous efflorescences frequently occur upon the surface, in various parts of the country, and incrustations of salt, of considerable {234} thickness, are to be found in some few places south of the Arkansa river. As to the existence of rock salt in a mineral state some doubts are to be entertained, if the decision is to rest upon the character of the specimens exhibited as proofs of the fact. The several examples of this formation that we have witnessed, are evidently crystalline salt deposited by a regular process of evaporation and crystallization, and formed into concrete masses or crusts upon the surface of the ground.

Indications of coal are occasionally to be seen, but this mineral does not probably occur in large quantities. The geological character of this section is not such as to encourage the search for valuable minerals. A deep crust of secondary sandstone, occasionally alternating with breccia, with here and there a superstratum of rocks of a primitive type, are the principal formations that present themselves.

Of the animals of this region, the buffaloe or bison ranks first in importance, inasmuch as it supplies multitudes of savages not only with the principal part of their necessary food, but also contributes to furnish them with warm clothing. The flesh of this animal is equal, if not superior, to beef, and affords not only a savoury but a wholesome diet. A large proportion of this section, commencing at the assumed meridian, and extending westward to within one hundred miles of the Rocky Mountains, constitutes a part only of their pasture ground, over which they roam in numbers to an incredible amount. Their range extends northwardly and southwardly of the section, as far as we have any particular account of the country. The animal next in importance is the wild horse, a descendant, no doubt, of the Spanish breed of horses, to which its size, form and variety of colours, show that it is nearly allied. In regard to their contour, symmetry, &c. they afford all the varieties common to that breed of horses. They are {235} considerably numerous in some parts of the country, but not abundant. They are generally collected in gangs, but are sometimes solitary.

Grizzly or white bears are frequently to be seen in the vicinity of the mountains. They are much larger than the common bear, endowed with great strength, and are said to be exceedingly ferocious. The black or common bears are numerous in some parts of the country, but none of these animals are found remote from woodlands, upon the products of which they in a great measure depend for their subsistence.

The common deer are to be met with in every part of this section, but are most numerous in the vicinity of woodlands. The black-tailed or mule deer is found only in the neighbourhood of the mountains; hilly and broken lands seem to afford them their favourite pasture ground. The elk is also an inhabitant of this section, but is not to be found remote from woodlands. The cabric wild goat, or, as it is more frequently called, the antelope, is common. They are numerous, and with the buffaloe are the common occupants of the plains, from which they retire only in quest of water.

Wolves are exceedingly numerous, particularly within the immediate range of the buffaloe. Of these there are many varieties, distinguishable by their shape, size and colour.

The marmot, commonly called the prairie dog, is more abundant throughout this section than any other quadruped. They live in villages scattered in every direction, and thickly inhabited; a single village in some instances occupying a tract of ground three or four miles in extent. Their habitations are burrows three or four inches in diameter, situated at the distance of fifteen or twenty paces asunder. Their habits and manners in other respects are peculiarly interesting. They subsist on vegetables; their {236} flesh is similar to that of the ground hog, and their hair equally as coarse.

The beaver, otter, mink, and muskrat, are numerous upon the rivers, creeks, and rivulets issuing from the mountains, and generally upon those whose valleys are supplied with woodland.

Badgers, raccoons, hares, polecats, porcupines, many varieties of squirrels, panthers, wild cats, lynxes and foxes of several species, are also inhabitants of this section. Besides these, the country affords a great variety and abundance of reptiles and insects, both venomous and harmless.
