Note M-4 — MEMOIR OF ZEBULON MONTGOMERY PIKE. BY ELLIOTT COUES.

Historical Register of the United States Army, from its Organization, September 29th, 1789, to September 29th, 1889. By F. B. Heitman, Clerk, Adjutant General's office, War Department, Washington, D. C., 1890, 1 vol., large 8vo, pp. 890. I make a point throughout Pike of identifying as far as possible the officers whose names appear in his text, giving in brief their official records, and doing the same for those who are mentioned in my own writing. I am indebted to Heitman's invaluable work for most such matter.
