Lord Kingsborough was born in 1795, and died at Dublin in 1837. His "Antiquities of Mexico," ten volumes, imperial folio, were published in London between 1830-48, consequently, since he died in 1837, some of the volumes were issued after his death. His theory is that the Indians are descendants of the Lost Tribes of Israel, and to the establishment of this view he bends all his energies. He is open to the charge of being over zealous for his theory, and doubtless has been somewhat extravagant in his assumptions of proofs--in matters of detail, at least; but, after all proper discount is made for the over-zeal of an enthusiast--fanatic, if you will,--there remains a body of evidence in his works for the Hebrew origin of native American races which has never been successfully disposed of by those who dispute his theory. Even Bancroft, who holds his theory in contempt, is forced to admit that his "enthusiasm is never offensive," and further says of him, "There is a scholarly dignity about his work which has never been attained by those who have jeered and railed at him." [1] Adair's work, "History of the North American Indians," is included in the eighth volume of Kingsborough's works. James Adair was an English trader among the North American Indians from 1735 to 1775--forty years. It was in 1775 that his work was published. His observations were confined to the North American Indians; hence these three authors may be said to cover the entire field of our investigation. I shall give extracts from all these writers, making use of Bancroft's abridgment of their works as being at once accurate and most accessible to the reader. I. _Garcia._ I begin with Garcia:
