When they [the Ioway] separated from the first Indian tribe, or family, to hunt game, their first location was near the mouth of a river, where there were large sand-bars, from which the wind blew quantities of sand or dust upon their faces, from which they were called Pa-hu-chas or Dusty-noses. _Per contra_: During November, 1873, when I was at the former Winnebago Agency, Blue Earth County, Minnesota, I mentioned the above theory of the Ioway name to the intelligent Winnebago ex-Chief “Baptiste,” the Half-Breed, who in his youthful wanderings had lived a considerable time on the Missouri amongst the Ioway. He smiled at it, and, in his broken English at first and then through ex-Interpreter Menaige, who was present, said, that the Ioway name meant _Dusty_, or Dusty Gray, _Heads_, and that it occurred in this way: Living on the Missouri as they had done in the earliest time: wandering away from it and then wandering back again; they were accustomed to bathe a great deal in its yellow-muddy waters; and that when they dried off after coming out of the water, the sediment of the water remained on their _heads_ making them look _dusty_ and _gray_; and this was the true reason they became the Pähutch’æ, or _Dusty-Head_ Tribe. Baptiste said this was the accepted theory amongst the old people of the Ioway as to the way Pähutch’æ came to be their name. The Winnebago cognomen for them, which is Wähōtch’ærä, the _Gray-Ones_, is evidently but a modification of the same _Dusty-Head_ idea: (in the Hōtchank’ærä language hōtch is _gray_ and rähätch, _ashes_). And such modification is, also, I think the Dakota-Sioux name for them of Äyu′h’äpä, notwithstanding the Dakota-Sioux Lexicon gives it as meaning the _Drowsy-Ones_, and to doubt such authority may seem presumptuous. But, in these investigations I have noticed, that aboriginal nations, unless there is some special reason to the contrary—for instance a special enmity—(as the Chippeway name for the Sioux of Ōpwan’äk, “those whom we roast,”) all endeavor to _translate_ into their own vernacular the names of neighboring tribes, rather than adopt them bodily: a notable instance of which is, that the name _Saulteurs_, people of the _Sault_ or _Leap_ or _Rapids_, is repeated in idea but in different forms by both the Winnebago and the Sioux, the latter terming them Hähä’towa and the former Ræh’ätchē’rä, both meaning, alike, “_The Falls Dwellers_.” Sometimes, in these dialectical translations, the original meaning of the tribal name was correctly rendered, and sometimes not: the early French in fact, made frequent failures. Now, the Sioux were well acquainted with the Ioway. They were, at the advent of the whites, their allies and neighbors, living as the Ioway did in 1700, on the borders of Iowa and Minnesota, about the headwaters of the Blue Earth and Des Moines rivers:[59] though they soon wandered from there to the Missouri again. The Dakota must
