[FN] _Horikans_ was written by De Laet, in 1624, as the name of an Indian tribe living at the head waters of the Connecticut. On an ancient map _Horicans_ is written in Lat. 41, east of the Narragansetts on the coast of New England. In the same latitude _Moricans_ is written west of the Connecticut, and _Horikans_ on the upper Connecticut in latitude 42. _Morhicans_ is the form on Carte Figurative of 1614-16, and _Mahicans_ by the Dutch on the Hudson. The several forms indicate that the tribe was the _Moricans_ or _Mourigans_ of the French, the _Maikans_ or _Mahikans_ of the Dutch and the _Mohegans_ of the English. It is certain that that tribe held the headwaters of the Connecticut as well as of the Hudson. The novelist, Cooper, gave life to De Laet's orthography in his "Last of the Mohegans." Ticonderoga, familiar as the name of the historic fortress at Lake George, was written by Sir William Johnson, in 1756, _Tionderogue_ and _Ticonderoro,_ and in grant of lands in 1760, "near the fort at _Ticonderoga._" Gov. Golden wrote _Ticontarogen,_ and an Iroquoian sachem is credited with _Decariaderoga._ Interpretations are almost as numerous as orthographies. The most generally quoted is from Spofford's Gazetteer: "_Ticonderoga,_ from _Tsindrosie_, or _Cheonderoga,_ signifying 'brawling water,' and the French name, _Carillon,_ signifying 'a chime of bells,' were both suggested by the rapids upon the outlet of Lake George." The French name may have been so suggested, but neither _Tsindrosie_ or _Cheonderoga_ means "brawling water." The latter is probably an orthography of _Teonderoga._ Ticonderoga as now written, is from _Te_ or _Ti,_ "dual," two; _Kaniatare,_ "lake," and _-ogen,_ "intervallum, divisionem" (Bruyas), the combination meaning, literally, "Between two lakes." Horatio Hale wrote me of one of the forms: "_Dekariaderage,_ in modern orthography, _Tekaniataroken,_ from which Ticonderoga, means, simply, 'Between two lakes.' It is derived from _Tioken,_ 'between,' and _Kaniatara,_ 'lake.' Its composition illustrates a peculiar idiom of the Iroquoian language, _Tioken_ when combined with a noun, is split in two, so to speak, and the noun inserted. Thus in combining _Tioken_ with _Ononte,_ 'mountain,' we have _Ti-ononte-oken,_ 'Between two mountains,' which was the name of one of the Mohawk castles--sometimes written Theonondiogo. In like manner, _Kaniatare,_ 'lake,' thus compounded, yields _Te-kaniatare-oken,_ 'Between two lakes.' In the Huron dialect _Kaniatare_ is contracted to _Yontare_ or _Ontare,_ from which, with _io_ or _iyo,_ 'great,' we get _Ontario_ (pronounced Ontareeyo), 'Great lake' which, combined with _Tioken,_ becomes _Ti-onteroken,_ which would seem to be the original of Colden's _Tieronderoga._"
