In other parts, and farther West, between the Camanchee village and the Canadian, we passed over a similar surface for many miles denuded, with the exception of here and there little bunches of grass and wild sage, a level and exposed surface of solid gypsum, of a dark grey colour: and through it, occasionally, as far as the eye could discover, to the East and the West streaks of three and five inches wide of snowy gypsum, which was literally as white as the drifted snow. Of saltpetre and salt, there are also endless supplies; so it will be seen that the mineral resources of this wilderness country are inexhaustible and rich, and that the idle savage who never converts them to his use, must soon yield them to the occupation of enlightened and cultivating man. In the vicinity of this post there are an immense number of Indians, most of whom have been removed to their present locations by the Government, from their Eastern original positions, within a few years past; and previous to my starting with the dragoons, I had two months at my leisure in this section of the country, which I used in travelling about with my canvass and note-book, and visiting all of them in their villages. I have made many paintings amongst them, and have a curious note-book to open at a future day, for which the reader may be prepared. The tribes whom I thus visited, and of whom my note-book will yet speak, are the _Cherokees_, _Choctaws_, _Creeks_, _Seminoles_, _Chickasaws_, _Quapaws_, _Senecas_, _Delawares_, and several others, whose customs are interesting, and whose history, from their proximity to, and dealings with the civilized community, is one of great interest, and some importance, to the enlightened world. Adieu. LETTER—No. 46. ALTON, _ILLINOIS_. A few days after the date of the above Letter, I took leave of Fort Gibson, and made a transit across the prairies to this place, a distance of 550 miles, which I have performed entirely alone, and had the satisfaction of joining my wife, whom I have found in good health, in a family of my esteemed friends, with whom she has been residing during my last year of absence. While at Fort Gibson, on my return from the Camanchees, I was quartered for a month or two in a room with my fellow-companion in misery, Captain Wharton, of the dragoons, who had come in from the prairies in a condition very similar to mine, and laid in a bed in the opposite corner of the room; where we laid for several weeks, like two grim ghosts, rolling our glaring and staring eye-balls upon each other, when we were totally unable to hold converse, other than that which was exchanged through the expressive language of our hollow, and bilious, sunken eyes.
