In their own language they call themselves See-pohs-ka-mi-mah-ka-kee (the people of the pheasants), which Mr. Catlin thinks they would not do if they had not lived where pheasants abounded, as in Pennsylvania, Ohio, and Indiana, for there are none on the prairies until within six or seven hundred miles of the Rocky Mountains. The most convincing proof, probably, to the mind of Mr. Catlin, and to all others who have studied the possible identification of the Mandans with Madoc's colony, is found in their language. The resemblance in form and sound is so very marked that it cannot escape the eye and ear of any individual, much less those of a Welshman. It is expected that he would catch the soonest any similarity in the two languages,--the Mandan and the Welsh. And fortunately there are too many instances of this similarity to admit for a moment the idea of chance or coincidence. That the reader may see that this is the case, his attention is called to the subjoined table of words selected from the English, Mandan, and Welsh, and their pronunciations: ENGLISH. MANDAN. WELSH.
