Kay-au-do-ros-sa (modern), _Kancader-osseras, Kanicader-oseras_ (primary), the name given as that of a stream of water, of a district of country, and of a range of mountains, was originally the name of the stream now known as Fish Creek, [FN] the outlet of Saratoga Lake, and signifies, literally, "Where the lake mouths itself out." Horatio Hale wrote me: "Lake, in Iroquois, is, in the French missionary spelling, _Kaniatare,_ the word being sounded as in Italian. _Mouth_ is _Osa,_ whence (writes the Rev. J. A. Cuoq in his Lexique de la langue Iroquois), _Osara,_ mouth of a river, 'boudhe d'un fleure, embouchure d'une riviere.' This word combined would give either _Kauicatarosa_ or _Kaniatarossa,_ with the meaning of 'Lake mouth,' applicable to the mouth of a lake, or rather, according to the verbalizing habit of the language, 'the place where the lake disembogues,' literally, 'mouths itself out.'" To which J. B. N. Hewitt added the explanation, "Or flood-lands of the lake--the overflow of the lake." * * * * * [FN] "About Kayaderossres Creek and the lakes in that quarter." "The chief tract of hunting land we have left, called Kayaderossres, with a great quantity of land about it." (Doc. Hist. N. Y., ii, 110.) The stream drains an extensive district of country, flows into and becomes the outlet of Saratoga Lake, and is now known as Fish Creek and Fish Kill, a very cheap substitute for the expressive Mohawk term. Adirondacks, or Ratirontaks, a name now improperly applied to the mountainous district of northern New York, is said to have been primarily bestowed by the Iroquois on a tribe occupying the left bank of the St. Lawrence above the present site of Quebec, who were called by the French Algonquins specifically, as representatives of a title which had come to be of general application to a group of tribes speaking radically the same language. [FN-1] The term is understood to mean, "They eat trees," _i. e._ people Who eat the bark of certain trees for food, presumably from the climatic difficulty in raising corn in the latitude in which they lived. [FN-2] Horatio Hale analyzed the name: "From _Adi,_ 'they'; _aronda,_ 'tree,' and _ikeks,_ 'eat.'" The name was not that of the district, nor is it convertible with _Algonquin_. The later is a French rendering of _Algoumquin,_ from _A'goumak,_ "On the other side of the river," _i. e._ opposite their neighbors lower down. (Trumbull.) Schoolcraft gave substantially the same interpretation from the Chippewa, "_Odis-qua-guma,_ 'People at the end of the waters,'" making its application specific to the Chippewas as the original Algonquins, instead of the Ottawas. The accepted interpretation, "Country of mountains and forests," is correct only in that that it is descriptive of the country. The record names of the district are _Cough-sagh-raga_ and _Canagariarchio_, the former entered on Pownal's map with the addition
