You ask if there is any book that pretends to give any account of the traditions of the Indians, or how one can acquire an idea of them? Some scanty accounts of their traditions, but fuller of their customs and characters, are given us by most of the early travellers among them; these you know were mostly French. Lafitan, among them, and Adair an Englishman, have written on this subject; the former two volumes, the latter one, all in 4to. But unluckily Lafitan had in his head a preconceived theory on the mythology, manners, institutions and government of the ancient nations of Europe, Asia and Africa, and seems to have entered on those of America only to fit them into the same frame, and to draw from them a confirmation of his general theory. He keeps up a perpetual parallel, in all those articles, between the Indians of America and the ancients of the other quarters of the globe. He selects, therefore, all the facts and adopts all the falsehoods which favor his theory, and very gravely retails such absurdities as zeal for a theory could alone swallow. He was a man of much classical and scriptural reading, and has rendered his book not unentertaining. He resided five years among the Northern Indians, as a Missionary, but collects his matter much more from the writings of others, than from his own observation. Adair too had his kink. He believed all the Indians of America to be descended from the Jews; the same laws, usages, rites and ceremonies, the same sacrifices, priests, prophets, fasts and festivals, almost the same religion, and that they all spoke Hebrew. For, although he writes particularly of the Southern Indians only, the Catawbas, Creeks, Cherokees, Chickasaws and Chocktaws, with whom alone he was personally acquainted, yet he generalizes whatever he found among them, and brings himself to believe that the hundred languages of America, differing fundamentally every one from every other, as much as Greek from Gothic, yet have all one common prototype. He was a trader, a man of learning, a self-taught Hebraist, a strong religionist, and of as sound a mind as Don Quixotte in whatever did not touch his religious chivalry. His book contains a great deal of real instruction on its subject, only requiring the reader to be constantly on his guard against the wonderful obliquities of his theory. The scope of your inquiry would scarcely, I suppose, take in the three folio volumes of Latin of De Bry. In these, facts and fable are mingled together, without regard to any favorite system. They are less suspicious, therefore, in their complexion, more original and authentic, than those of Lafitan and Adair. This is a work of great curiosity, extremely rare, so as never to be bought in Europe, but on the breaking up and selling some ancient library. On one of these occasions a bookseller procured me a copy, which, unless you have one, is probably the only one in America.
