Note 145 — LETTER III
Reading edition
De Smet had been associated with Nicollet in his exploration of the Missouri River in 1839. Nicollet intended another expedition westward, but was detained in Washington by business connected with the publication of his hydrographical map, and the report to Congress, and was never again in the Western country. See his letter in Chittenden and Richardson, De Smet, iv, pp. 1552, 1553.
