The first journal, entitled, "Exchange Book A 1833," includes notes on minerals, individuals, and destinations spanning 6/15/1833-4/7/1843.
 
Jackson maintained two sequential volumes between 1840 and 1841. The 1840 notebook contains entries written between 9/21-10/6, and devotes significant attention to non-geological affairs, such as towns and people, husbandry, farming methods, and yields for oats, potatoes, wheat, and various dairy products. The 1841 volume is considerably more focused on geology, with detailed accounts of granite, smoky quartz, limestone, iron, marble, and lead mines and quarries across New England. While these entries are almost single-mindedly focused on geology, there are instances when Jackson considers other affairs. For example, between 7/4-7/9, he briefly acknowledges the illness, death, and funeral of his daughter, Susan
 
on 7/20, he notes a "late speculation mania
 
" and shortly after an 8/17 entry, he describes a visit to Quebec with some commentary on the Lower Canada Rebellion. This journal features numerous hand-drawn diagrams, many of which are noteworthy for their excellent draftsmanship (8/15 and 9/15).
 
An 1849 journal continues in much the same vein, detailing geological discoveries, carefully rendered diagrams (e.g. 8/4), and barometric readings.
 
Jackson also maintained an account book that spans January 1855-October 1857. That volume features a letter to a "Humphrey Esq.," dated 1/6/186[sic] and a signed entry concerning a dispute regarding certified copies of a document, dated 8/21 (presumably 1857). Interested researchers may choose to review other notebooks in the Geology Journals box, such as a catalog of rocks and minerals from Lake Superior and a scrapbook maintained by Mrs. C.J. Jackson, dated 1881.

Charles Thomas Jackson maintained at least five notebooks that could be classified as diaries, which detail geological expeditions undertaken between 1833-1849. These diaries may interest researchers considering Jackson's geological surveys, New England farming, husbandry, and geology, and the Lower Canada Rebellion.

The Expedition Journals feature three travel journals bound in a single volume. The first two document William Dunbar's expedition up the Red and Ouachita Rivers to the Hot Springs of Arkansas in 1804-1805. Although few contemporary locations are named, they include numerous coordinates that researchers may use to track the journey. "Journal... to the Mouth of the Red River" furnishes particularly lush descriptions of the settlers (e.g. 10/21/1804) and indigenous peoples (11/24/1804) in the region. The second journal records technical data from the expedition, including a thermometrical log. Both journals dovetail nicely with that of traveling companion, George Hunter, also available at the APS (Mss.B.H912).; The final journal recounts an expedition to explore the geography of the Mississippi River led by Lt. Zebulon Montgomery Pike between 1805-1806. The Pike journal provides a daily account of the activities of the expedition during an early exploration into present day Minnesota. Notably, that journal includes significant attention to exchanges between settlers and local indigenous tribes (e.g. 9/3/1805, 9/10/1805, 9/24-25/1805). That volume has been 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 it was edited in Donald Jackson, ed., The Journals of Zebulon Pike: with Letters and Related Documents (Norman, Okla., 1966). Bound together, the Dunbar and Pike volumes ought to interest a range of scholars researching U.S. exploration and Native America in the early national period.
