But, above all, we must better study all the spoken languages and dialects. It is strange that we hardly know anything, and sometimes nothing at all, on the languages of many existing tribes, with whom we have intercourse in both Americas. It would be desirable to procure at least a vocabulary of 100 essential words, in each. Such words, including the cardinal numbers, will soon become the key of ethnographical philology. While the additional study of phonology or sounds of languages, their idioms and grammars, their roots, and verbs, the alphabets, glyphs and symbols used to communicate ideas, will combine to furnish the complete knowledge of philology as a separate science. Although I have not always carried so far my researches; I did so for a few, applying chiefly myself to the essential features of languages; and the unexpected results will be surprising. American anthropography will teach that there were men of all sizes, features and complexions, in this hemisphere before 1492: notwithstanding the false assertions of many writers, who take one nation for the whole American group. The Uskihs, the Puruays, the Parias, the Chons, &c. were as white as the Spaniards, 50 such tribes were found in South America; while many tribes of Choco, the Manabis, the Yaruras, &c., were as black as negroes. All the other shades of brown, tawny and coppery, were scattered every where. There was not a single red man in America, unless painted such. Some tribes had scanty beards as the Tartars, Chinese, Berbers, &c., others bushy beards. The Tinguis or Patagons were 7 or 8 feet high, and the Guaymas only 4 or 5 feet. 6. _Traditions and Annals._ Many American nations preserve a memory of historical events by unwritten traditions, repeated from fathers to sons; or communicated orally by the priests, chiefs or elderly men. Many are preserved yet to this day, by frequent repetitions, being embodied in songs, hymns, maxims, tales, drawings, or even symbolic figures and signs. Many of those traditions are precious for history, notwithstanding the fables, allegories, metaphors, personifications, &c., which partly conceal them or render the meaning obscure. We must learn to decipher them as we do old inscriptions and medals.
