west longitude.

The land is rich and fertile, especially by the sides of numerous streams, where the soil is sometimes of a deep red colour, and at others entirely black.

The aspect of this region is well diversified, and though the greatest part of it must be classified under the denomination of rolling prairies, yet woods are very abundant, principally near the rivers and in the low flat bottoms: while the general landscape is agreeably relieved from the monotony of too great uniformity by numerous mountains of fantastical shapes and appearance, entirely unconnected with each other, and all varying in the primitive matter of their conformation.
Masses of native copper are found at almost every step, and betwixt two mountains which spread from east to west in the parallel of the rivers Buona Ventura and Calumet, there are rich beds of galena, even at two or three feet under ground; sulphur and magnesia appear plentiful in the northern districts; while in the sand, of the creeks to the south gold dust is occasionally collected by the Indians.

The land is admirably watered by three noble streams--the Buona Ventura, the Calumet, and the Nu eleje sha wako, or River of the Strangers, while twenty rivers of inferior size rush with noise and impetuosity from the mountains, until they enter the prairies, where they glide smoothly in long serpentine courses between banks covered with flowers and shaded by the thick foliage of the western magnolia.

The plains, as I have said, are gently undulating, and are covered with excellent natural pastures of moskito-grass, blue grass, and clover, in which innumerable herds of buffaloes, and mustangs, or wild horses, graze, except during the hunting season, in undisturbed security.
The Shoshones[6] are indubitably a very ancient people.
