Scope and Content Note

This series consists of 20 volumes of final calculations, accounts, and estimates for construction, repairs, and enlargement of the Eastern Division of the Erie Canal and 1 volume of final calculations relating to the Middle Division of the Cayuga and Seneca Canal.

These volumes mainly deal with the first Erie Canal enlargement which began in 1836 and was completed in 1862. The volumes consist of calculations, accounts, and estimates for the enlargement of various sections of the canal as well as the construction of structures related to the canal (bridges, locks, culverts, etc.). Most of the data in these volumes is presented in a tabular format.

The volumes generally include profile diagrams of the canal; calculations of cubic footage of excavation, embankment, lining, and other types of work; formulae used to estimate cubic footage; detailed sketches and maps; descriptions of the work being done; and total amounts.

Included after each portion of the volume devoted to a particular section of the canal is a summary that lists the type of work that was completed in that section (grubbing, masonry, lining, etc.); materials used; and extra work. A final account is often included which lists the quantity or material used; purpose for which the material was used; price of each item; and total cost.

The content of volumes 10-13 is similar to the rest of the series, but these are noteworthy due to their artistic value. These volumes contain exceptional examples of calligraphy and cartouches, especially in headings and subheadings. There are also very detailed sketches of canal structures, sketch maps, and unrelated drawings. Although not identified, notes in the volumes left by employees of the transferring agency suspect that the calligraphy and sketches were done by surveyor and draftsman David Vaughan. Vaughan was known for artistic flourishes in his maps and the style found in these volumes is comparable to his.
