A second group, very small in numbers but extremely interesting to the student of ethnology, comprises the Minnitarees and Mandans on the upper Missouri.[35] The remnants of these tribes now live together in the same village, and in personal appearance, as well as in intelligence, they are described as superior to any other red men north of New Mexico. From their first discovery, by the brothers La Verendrye in 1742, down to Mr. Catlin's visit nearly a century later, there was no change in their condition,[36] but shortly afterward, in 1838, the greater part of them were swept away by small-pox. The excellence of their horticulture, the framework of their houses, and their peculiar religious ceremonies early attracted attention. Upon Mr. Catlin they made such an impression that he fancied there must be an infusion of white blood in them; and after the fashion of those days he sought to account for it by a reference to the legend of Madoc, a Welsh prince who was dimly imagined to have sailed to America about 1170. He thought that Madoc's party might have sailed to the Mississippi and founded a colony which ascended that river and the Ohio, built the famous mounds of the Ohio valley, and finally migrated to the upper Missouri.[37] To this speculation was appended the inevitable list of words which happen to sound somewhat alike in Mandan and in Welsh. In the realm of free fancy everything is easy. That there was a Madoc who went somewhere in 1170 is quite possible, but as shrewd old John Smith said about it, "where this place was no history can show."[38] But one part of Mr. Catlin's speculation may have hit somewhat nearer the truth. It is possible that the Minnitarees or the Mandans, or both, may be a remnant of some of those Mound-builders in the Mississippi valley concerning whom something will presently be said. [Footnote 35: An excellent description of them, profusely illustrated with coloured pictures, may be found in Catlin's _North American Indians_, vol. i. pp. 66-207, 7th ed., London, 1848; the author was an accurate and trustworthy observer. Some writers have placed these tribes in the Dakota group because of the large number of Dakota words in their language; but these are probably borrowed words, like the numerous French words in English.] [Footnote 36: See Francis Parkman's paper, "The Discovery of the Rocky Mountains," _Atlantic Monthly_, June, 1888. I hope the appearance of this article, two years ago, indicates that we have not much longer to wait for the next of that magnificent series of volumes on the history of the French in North America.] [Footnote 37: _North American Indians_, vol. ii., Appendix A.] [Footnote 38: Smith's _Generall Historie of Virginia, New England and the Summer Isles_, p. 1, London, 1626.] [Sidenote: Pawnees, etc.]
