For Sir Alexander Mackenzie see Franchère's Narrative, in our volume vi, p. 185, note 4. For the Blackfeet and Arapaho see our volume v, p. 225, note 120. 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. Consult Chittenden, Fur-Trade, ii, pp. 852, 853.—Ed.
