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 first three volumes in the Albert C. Peale Papers are the most idiosyncratic. They include a daybook with weather observations (3/10-5/18/1864), a diary associated with a tour of Washington, D.C. during President Andrew Johnson's administration (c.1865-1869), and a lecture notebook pertaining to studies at the University of Pennsylvania. Of those early volumes, A. C. Peale's diary of his tour of Washington D.C. is perhaps most noteworthy. It recounts his travels from Philadelphia through Wilmington and Baltimore, tours of monuments and government buildings, including the U.S. Patent Office, Government Printing Office, and White House, and a handshake with President Johnson during that tour (2/7/1865).
 
The remaining six diaries (1872-1877) are devoted to various western expeditions in what is today Colorado, Wyoming, and Utah. In his first diary (5/15-7/20/1872), A. C. Peale recounts his travel by rail from Philadelphia to Omaha, from which he would conduct his western expeditions. The second volume (5/29-8/15/1873), devotes significant attention to his mineralogical work, including gathering fossils, documenting canyons and volcanic peaks, and ascending various peaks and plateaus. Notably, he references photographer William Henry Jackson, who he writes "disturbed us to take a picture." (8/8/1873). The next two diaries (8/16-10/26/1873 and 5/14/1873-7/18/1874) recount the movement of the party over the next year, most especially campsites, weather problems, and travel constraints. The latter volume also records trip to Savannah (11/20/1873) and includes some accounts in the back of the journal.
 
The final two volumes continue in much the same vein, but offer records of interactions with Bannock and Shosoni Indians. The diary dated 7/19-11/10/1874 documents A. C. Peale's expeditions along branches of the Gunnison River, during which he encounters local tribes on multiple occasions (8/29/1874 and 9/20/1874). The final diary (5/27-10/9/1877), which corresponds with trips into western Wyoming, records numerous interactions with Bannock and Shosoni. For example, A. C. Peale writes that a Shosoni woman shares news of a fight between the whites and the Sioux (6/7/1877), and he commends the English of Bannock outside a ranch near Smith Fork (6/29/1877). Not all interactions are harmonious, however. A. C. Peale also records that Bannock kill two teamsters (8/8/1877) and that one of his his party (Gibbon) loses 300 new guns in a fight (8/23/1877).

Albert C. Peale Papers contain nine volumes that might be classified as diaries. These volumes traverse the American Civil War and Reconstruction period (1864-1877) and provide a window into the exploration and conquest of what is today Colorado, Wyoming, and Utah. The great-grandson of Charles Willson Peale, Albert Charles Peale was a prominent geologist in and author of numerous books in geology, mineralogy, and paleobotany. His journals offer a glimpse into his contributions to the Ferdinand Hayden expeditions, which explored and mapped the western United States. In furnishing numerous accounts of local indigenous peoples, including the Bannock and Shosoni, these volumes may interest scholars researching Native America, western exploration, the fields of geology and mineralogy, and the history of science.
