Newspapers.com now has The Washington Union (October 6, 1845) with "Sketches of the West" by Philip St. George Cooke. Many passages from Cooke's published "Sketches" were later revised and incorporated in the 1851-1853 magazine series "Scenes Beyond the Western Border," which in turn became Part II of the 1857 book, Scenes and Adventures in the Army.
