This collection includes three journals bound into one volume: two by Willima Dunbar and one by Zebulon Pike. Both manuscripts by William Dunbar document the expedition up the Red and Ouachita Rivers to the Hot Springs of Arkansas in 1804-1805. The "Journal... to the Mouth of the Red River" (200p.) is the fullest available record of the activities of the expedition from the time of their departure from St. Catharine's Landing on October 16, 1804, until their return to Natchez, Miss., on January 26, 1805. The "Journal of a geometrical survey" includes a record of course and distances as well as a thermometrical log and other brief notes. The two are bound together in a volume with Zebulon Montgomery Pike's journal of a voyage to the source of the Mississippi, 1805-1806. The Pike journal documents the expedition to explore the geography of the Mississippi River led by Lt. Zebulon Montgomery Pike in 1805-1806, and his attempts to purchase sites from the Dakota Indians for future military posts, and to bring influential chiefs back to St. Louis for talks. Less a literary masterpiece than a straightforward record in terse military prose, the journal provides a day by day account of the journey and the activities of Pike and his small contingent during this early exploration of present day Minnesota. It was printed with variations and omissions in An Account of Expeditions to the Sources of the Mississippi and through the Western Parts of Louisiana... (Philadelphia, 1810), and was edited in Donald Jackson, ed., The Journals of Zebulon Pike: with Letters and Related Documents (Norman, Okla., 1966).
