[Footnote 6: Travels of Lewis and Clarke, London, 1809, p. 189.] It was from an examination of Sibley’s vocabulary that Gallatin reached the conclusion of the distinctness of this language from any other known, an opinion accepted by most later authorities. A recent comparison of this vocabulary by Mr. Gatschet, with several Caddoan dialects, has led to the discovery that a considerable percentage of the Adái words have a more or less remote affinity with Caddoan, and he regards it as a Caddoan dialect. The amount of material, however, necessary to establish its relationship to Caddoan is not at present forthcoming, and it may be doubted if it ever will be, as recent inquiry has failed to reveal the existence of a single member of the tribe, or of any individual of the tribes once surrounding the Adái who remembers a word of the language. Mr. Gatschet found that some of the older Caddo in the Indian Territory remembered the Adái as one of the tribes formerly belonging to the Caddo Confederacy. More than this he was unable to learn from them. Owing to their small numbers, their remoteness from lines of travel, and their unwarlike character the Adái have cut but a small figure in history, and accordingly the known facts regarding them are very meager. The first historical mention of them appears to be by Cabeça de Vaca, who in his “Naufragios,” referring to his stay in Texas, about 1530, calls them Atayos. Mention is also made of them by several of the early French explorers of the Mississippi, as d’Iberville and Joutel. The Mission of Adayes, so called from its proximity to the home of the tribe, was established in 1715. In 1792 there was a partial emigration of the Adái to the number of fourteen families to a site south of San Antonio de Bejar, southwest Texas, where apparently they amalgamated with the surrounding Indian population and were lost sight of. (From documents preserved at the City Hall, San Antonio, and examined by Mr. Gatschet in December, 1886.) The Adái who were left in their old homes numbered one hundred in 1802, according to Baudry de Lozieres. According to Sibley, in 1809 there were only “twenty men of them remaining, but more women.” In 1820 Morse mentions only thirty survivors. ALGONQUIAN FAMILY. > Algonkin-Lenape, Gallatin in Trans. Am.
