[13] Nor is this to be at all wondered at, when we reflect on the barbarous state of those nations in their infancy, the imperfection of traditionary accounts of what had transpired centuries before, and in many instances the entire absence of a written language, by which, either to perpetuate events, or enable the philosopher by analogy of language to ascertain their affinity with other nations. Conjectural then as must be every disquisition as to the manner in which this continent was first peopled, still however, as many men eminent for learning and piety have devoted much labor and time to the investigation of the subject, it may afford satisfaction to the curious to see some of those speculations recorded. Discordant as they are in many respects, there is nevertheless one fact as to the truth of which they are nearly all agreed; Mr. Jefferson is perhaps the only one, of those who have written on the subject, who seems to discredit the assertion that America was peopled by emigrants from the old world. How well the conjecture, that the eastern inhabitants of Asia were descendants of the Indians of America can be supported by any knowledge which is possessed of the different languages spoken by the Aborigines, will be for others to determine. "Neque confirmare argumentis, neque refellere, in animo est; ex ingenio suo, quisque demat vel addat fidem."
Among those who have given to the world their opinions on the origin of the natives of America, is Father Jos. Acosta, a Jesuit who was for some time engaged as a missionary among them. From the fact that no ancient author has made mention of the [14] compass, he discredits the supposition that the first inhabitants of this country found their way here by sea. His conclusion is that they must have found a passage by the North of Asia and Europe which he supposes to join each other; or by those regions which lie southward of the straits of Magellan.
Gregorio Garcia, who was likewise a missionary among the Mexicans and Peruvians, from the traditions of those nations, and from the variety of characters, customs, languages and religion, observable in the new world, has formed the opinion that it was peopled by several different nations.
