Chicago, June 20.

There can be no two places in the world more completely thoroughfares than this place and Buffalo. They are the two correspondent valves that open and shut all the time, as the life-blood rushes from east to west, and back again from west to east.

Since it is their office thus to be the doors, and let in and out, it would be unfair to expect from them much character of their own. To make the best provisions for the transmission of produce is their office, and the people who live there are such as are suited for this; active, complaisant, inventive, business people. There are no provisions for the student or idler; to know what the place can give, you should be at work with the rest, the mere traveller will not find it profitable to loiter there as I did.

Since circumstances made it necessary for me so to do, I read all the books I could find about the new region, which now began to become real to me. All the books about the Indians, a paltry collection, truly, yet which furnished material for many thoughts. The most narrow-minded and awkward recital, still bears some lineaments of the great features of this nature, and the races of men that illustrated them.

Catlin's book is far the best. I was afterwards assured by those acquainted with the regions he describes, that he is not to be depended on for the accuracy of his facts, and, indeed, it is obvious, without the aid of such assertions, that he sometimes yields to the temptation of making out a story. They admitted, however, what from my feelings I was sure of, that he is true to the spirit of the scene, and that a far better view can be got from him than from any source at present existing, of the Indian tribes of the far west, and of the country where their inheritance lay.

Murray's travels I read, and was charmed by their accuracy and clear broad tone. He is the only Englishman that seems to have traversed these regions, as man, simply, not as John Bull. He deserves to belong to an aristocracy, for he showed his title to it more when left without a guide in the wilderness, than he can at the court of Victoria. He has, himself, no poetic force at description, but it is easy to make images from his hints. Yet we believe the Indian cannot be looked at truly except by a poetic eye. The Pawnees, no doubt, are such as he describes them, filthy in their habits, and treacherous in their character, but some would have seen, and seen truly, more beauty and dignity than he does with all his manliness and fairness of mind. However, his one fine old man is enough to redeem the rest, and is perhaps the relic of a better day, a Phocion among the Pawnees.

Schoolcraft's Algic Researches is a valuable book, though a worse use could hardly have been made of such fine material. Had the mythological or hunting stones of the Indians been written down exactly as they were received from the lips of the narrators, the collection could not have been surpassed in interest, both for the wild charm they carry with them, and the light they throw on a peculiar modification of life and mind. As it is, though the incidents have an air of originality and pertinence to the occasion, that gives us confidence that they have not been altered, the phraseology in which they were expressed has been entirely set aside, and the flimsy graces, common to the style of annuals and souvenirs, substituted for the Spartan brevity and sinewy grasp of Indian speech. We can just guess what might have been there, as we can detect the fine proportions of the Brave whom the bad taste of some white patron has arranged in frock-coat, hat, and pantaloons.

The few stories Mrs. Jameson wrote out, though to these also a sentimental air has been given, offend much less in that way than is common in this book. What would we give for a completely faithful version of some among them. Yet with all these drawbacks we cannot doubt from internal evidence that they truly ascribe to the Indian a delicacy of sentiment and of fancy that justifies Cooper in such inventions as his Uncas. It is a white man's view of a savage hero, who would be far finer in his natural proportions; still, through a masquerade figure, it implies the truth.

Irving's books I also read, some for the first, some for the second time, with increased interest, now that I was to meet such people as he received his materials from. Though the books are pleasing from their grace and luminous arrangement, yet, with the exception of the Tour to the Prairies, they have a stereotype, second-hand air. They lack the breath, the glow, the charming minute traits of living presence. His scenery is only fit to be glanced at from dioramic distance; his Indians are academic figures only. He would have made the best of pictures, if he could have used his own eyes for studies and sketches; as it is, his success is wonderful, but inadequate.

McKenney's Tour to the Lakes is the dullest of books, yet faithful and quiet, and gives some facts not to be met with elsewhere.
