Collection consists of a number of log books, time books, and other material related to an unnamed ditch and canal building company that operated near the town of San Acacio in Costilla County, Colorado, ca. 1909-1911. There is a book of computations and engineering calculations related to the Culebra-Eastdale Canal, a narrative book that contains similar information on this canal, a diary that lists activities of workers, the weather, and other information for the year of 1911 that appears to have been the property of hydrographer T.C. McPherson, and a record of various horses that were assigned to work on ditch construction.
