Scope and Content Note

Estimates of work done and materials delivered under contracts in force on a particular canal division were submitted monthly by the resident and division engineers to the Canal Commissioners.

The formats vary somewhat, but each estimate gives: number of canal section; name of contractors; quantity and type of materials and labor to be supplied; value of the same; and sometimes the unit price. All kinds of construction and repair work are included in the estimates - locks, aqueducts, other structures, and general excavation. The series also contains abstracts of the monthly estimates. The name of canal, date, and engineer's name are usually given on the cover. Monthly estimates from division and resident engineers were first required by legislation of 1850.
