The James Brindley Diaries contain two volumes related to his work on the Susquehanna, Conewago, Chesapeake, and Delaware canals. The first, entitled "Susquehanna and Conewago Canal Diary" (9/2/1794-1/20/1795) features highly detailed entries with significant technical data related to the project. Interspersed throughout, Brindley remarks on technical and logistical problems he encounters. For example, he notes that after the Canal Board fails to provide wages to workers, he has to advance funds to purchase tools. Perhaps most notably, he records the tensions related to Whiskey Rebellion in western Pennsylvania in an extended passage excerpted in Selected Quotations. The volume also includes drafts of letters to William Smith and Robert Morris.
 
The second volume, "Chesapeake and Delaware Canal Diary" (1/18-6/10/1803) recounts his early work on the Chesapeake and Delaware Canals, which would not be completed for another twenty-five years on account of funding problems. Brindley registers those issues in his early diary, discussing some of the legal and financial problems facing the project.

An engineer in the early national period, James Brindley worked on a host of canal projects in the United States, including the Potomac Canal in Maryland and the James River Canal in Virginia. His diaries, available in two volumes, document his work on the Susquehanna and Conewago Canal in 1794-1795 and the Chesapeake and Delaware Canal in 1803. The Conewago Canal, financed by Robert Morris and completed in 1797, improved access to Philadelphia markets. While the Chesapeake and Delaware Canal was debated as early as the 1760s, it was not funded until 1802 (and continued funding challenges would delay its completion for another 25 years). Brindley served as the lead engineer for both projects, and his journal provides valuable insights into early-nineteenth century canals and engineering, the Whiskey Rebellion, and U.S. government funding problems in the early national period.

Hiltzheimer provides a detailed and textured account of the young republic through scrupulous attention to the Constitutional Convention, election and reelection of George Washington, the Whiskey Rebellion, the Wyoming Valley incident, and the ascension of John Adams. Thanks to his career in Philadelphia politics (elected as a representative of the city in the Assembly in 1786), he furnishes first-hand accounts of George Washington, the funerals of Benjamin Franklin and David Rittenhouse, and numerous entries devoted to Pennsylvania luminaries including John and Clement Biddle, Joseph Morris, Levi Hollingsworth, Henry Drinker, and Timothy Matlack.
 
Hiltzheimer's journal also records family and personal details, including plague of locusts in 1766 and 1783, a great fire in 1794, and the death of his wife (3/11/1790) and loss of both his son and daughter to Yellow Fever (11/28/1793 and 12/29/1794 respectively). Indeed, his account of the Yellow Fever epidemic in Philadelphia is particularly exhaustive, with daily records of burials between 9/19-12/31/1793, as well as further accounts during the 1797 crisis, during which he ultimately contracted the disease that led to his death in September 1798.

The Jacob Hiltzheimer Diary spans 28 volumes and offers insight into the social life and customs of Philadelphia between the late colonial period to the early republic (1765-1798). Hiltzheimer describes a wide range of events, such as sleigh riding to ice skating to attending a large celebration of King George's Birthday on the banks of the Schuylkill with over 380 Philadelphians (before Independence). During the imperial crisis, Hiltzheimer's observations provide an interesting perspective on the events happening within the city, including the repeal of the Stamp Act, French troop movements, Cornwallis's surrender, and ensuing mob violence against suspected loyalists (e.g. 10/24/1781).
