And more Civil War Chinook Jargon by Phil Sheridan
A smoking gun, found in the book “A Catalogue of the Collection of Autographs Formed by Ferdinand Julius Dreer” (Philadelphia: printed for private distribution, 1893):
THE SAME [i.e. Philip Sheridan]. To George Suckley (Head Quarters Army of the Cumberland, June 19, 1863). 4o. 1p. A.L.S.
Postscript of five lines to a letter from Captain Mallory to Dr. Suckley, written in Chinook, the Indian “trade language” of Oregon.
— Volume 2, page 106.
This item would be great to track down and read. There’s certainly a story behind it. Note that the letter was written by Mallory, and the Jargon PS by Sheridan.
George Suckley (1830-1869) has made an appearance on my website previously. His intense Pacific Northwest experience before the Civil War included time at Fort Vancouver, Fort Steilacoom, and Fort Dalles; participation in Isaac Stevens‘s Pacific Railroad Survey; and a personal connection with Chinuk Wawa dictionarist George Gibbs.
