After the middle of the last century we begin to find new signs of the belief. Charles Beatty, in his _Journal of a two months’ tour with a view of promoting religion among the frontier inhabitants of Pennsylvania_ (Lond., 1768), finds traces of the lost tribes among the Delawares, and repeats a story of the Indians long ago selling the same sacred book to the whites with which the missionaries in the end aimed to make them acquainted. Gerard de Brahm and Richard Peters, both familiar with the Southern Indians, found grounds for accepting the belief. The most elaborate statement drawn from this region is that of James Adair, who for forty years had been a trader among the Southern Indians.[735] Jonathan Edwards in 1788 pointed out in the Hebrew some analogies to the native speech.[736] Charles Crawford in 1799 undertook the proof.[737] In 1816 Elias Boudinot, a man eminent in his day, contributed further arguments.[738] Ethan Smith based his advocacy largely on the linguistic elements.[739] A few years later an Englishman, Israel Worsley, worked over the material gathered by Boudinot and Smith, and added something.[740] A prominent American Jew, M. M. Noah, published in 1837 an address on the subject which hardly added to the weight of testimony.[741] J. B. Finlay, a mulatto missionary among the Wyandots, was satisfied with the Hebrew traces which he observed in that tribe.[742] Geo. Catlin, working also among the Western Indians, while he could not go to the length of believing in the lost tribes, was struck with the many analogies which he saw.[743] The most elaborate of all expositions of the belief was made by Lord Kingsborough in his _Mexican Antiquities_ (1830-48).[744] Since this book there has been no pressing of the question with any claims to consideration.[745] =J.= POSSIBLE EARLY AFRICAN MIGRATIONS.—These may have been by adventure or by helpless drifting, with or without the Canaries as a halting-place. The primitive people of the Canaries, the Guanches, are studied in Sabin Berthelot’s _Antiquités Canariennes_ (Paris, 1879) and A. F. de Fontpertuis’ _L’archipel des Canaries, et ses populations primitives_, also in the _Revue de Géographie_, June, 1882, not to mention earlier histories of the Canary Islands (see Vol. II. p. 36). Retzius of Stockholm traces resemblances in the skulls of the Guanches and the Caribs (_Smithsonian Rept._, 1859, p. 266). Le Plongeon finds the sandals of the statue Chac-mool, discovered by him in Yucatan, to resemble those of the Guanches (Salisbury’s _Le Plongeon in Yucatan_, 57). The African and even Egyptian origin of the Caribs has had some special advocates.[746] Peter Martyr, and Grotius following him, contended for the people of Yucatan being Ethiopian Christians. Stories of blackamoors being found by the early Spaniards are not without corroboration.[747] The correspondence of the African and South American flora has been brought into requisition as confirmatory.[748]
