I have also placed upon my canvass [Crystal Stone]; her countenance is rather pleasing, which is an uncommon thing amongst the Blackfeet her dress is made of skins, and being the youngest of a bevy of six or eight, and the last one taken under his [the chief's] guardianship, was smiled upon with great satisfaction (Letters and Notes, vol. 1, p. 30, pl. 13).
Painted at Fort Union in 1832. Crystal Stone also appears, full length, in cartoon 39, with her husband.
