These Indians were a "tribe who, according to Dr. Sibley, lived about the year 1800 near the old Spanish fort or mission of Adaize, 'about 40 miles from Natchitoches, below the Yattassees, on a lake called Lac Macdon, which communicates with the division of Red River that passes by Bayou Pierre' [Lewis and Clarke]. A vocabulary of about 250 words is all that remains to us of their language, which according to the collector, Dr. Sibley, 'differs from all others, and is so difficult to speak or understand that no nation can speak ten words of it. … 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." _J. W. Powell, Seventh Annual Report, Bureau of Ethnology, pages 45-46._ See preceding page. AMERICAN ABORIGINES: Adirondacks. "This is a term bestowed by the Iroquois, in derision, on the tribes who appear, at an early day, to have descended the Utawas river, and occupied the left banks of the St. Lawrence, above the present site of Quebec, about the close of the 15th century. It is said to signify men who eat trees, in allusion to their using the bark of certain trees for food, when reduced to straits, in their war excursions. The French, who entered the St. Lawrence from the gulf, called the same people Algonquins—a generic appellation, which has been long employed and come into universal use, among historians and philologists. According to early accounts, the Adirondacks had preceded the Iroquois in arts and attainments." _H. R.
