[53] Now Arrow River, rising in Baldy Range and flowing north-east, forming part of the boundary between Chouteau and Fergus counties. There is, however, an inadvertence in the use of this name. Lewis and Clark at first named Judith's River Bighorn, later abandoning this cognomen for its present name. The next stream above, on the south side, the explorers named Slaughter River for a herd of buffalo slaughtered by Indians below its cliffs. The published map, however, errs by placing here two rivers—Bighorn (which should be an alternate for Judith) and Slaughter Creek beyond the stone walls. Clark's "Summary Statement," Original Journals, vi, p. 62, gives this correctly.—Ed.
By a typographical error the Crow name for the Bighorn is given wrongly as "Ichpnaotsa" instead of "Ichpoa-tassa" (close articulation, ich guttural, tassa soft, short, and without emphasis).—Maximilian.

[55] This was the same tribe, possibly the same band, with whom the battle of Pierre's Hole occurred the preceding summer. See our volume xxi, pp. 69-72.—Ed.
[56] Possibly the first is the massacre at St. John's house, referred to by John McLean in Notes of Twenty-Five Years' Service in the Hudson's Bay Territory (London, 1849), i, pp. 234-237.

The tribal affinity between the Grosventres of the Prairies and the Arapaho was recognized by frequent visits of the former to the land of the latter.

[59] Most of the Grosventres used the Blackfoot language as well as their own, which is described as difficult by all travellers to this region.—Ed.
