Thayer's Notes:

a The phrase "but not at the seat of war" occurs frequently in the Register in connection with the Black Hawk War; the explanation in most cases is the one given in the biographical sketch of James Monroe (q.v.).

b Capt. Sitgreaves's expedition down the Zuñi and Colorado Rivers was the first systematic survey of the area, and laid a foundation for further surveys and ultimately the route of the Santa Fe Railroad. A summary is given by Grant Foreman in the introduction to his edition of Whipple's journal of 1853‑1854, pp15‑16. A photocopy of Sitgreaves' report is online at Archive.Org.
