The Adái, Atá-i, Háta-i, Adayes (incorrectly called _Adaize_) seem to have persisted at their ancient home, where they formed a tribe belonging to the Caddo confederacy. Charlevoix (Hist. de la Nouvelle France, ed. Shea VI, p. 24) relates that a Spanish mission was founded among the Adaes in 1715. A Spanish fort existed there, seven leagues west of Natchitoches, as late as the commencement of the nineteenth century. Baudry de Lozières puts their population at one hundred men (1802), and Morse (1822) at thirty, who then passed their days in idleness on the Bayou Pierre of Red river. Even at the present time they are remembered as a former division of the Caddo confederacy, and called Háta-i by the Caddo, who are settled in the southeastern part of the Indian Territory.
