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.
