Drawings

The drawings consist of geological surveys, land ownership, mine development and operations, mine buildings, mine services, railroads, equipment, site plans, plats, charts, diagrams, engineering drawings and sketches. This subseries also includes a variety of inventories, lists, and indices for the drawings. Coxe Brothers maintained a method of indexing their drawings and maps using index cards. Only some of the index cards exist and can be found in Box 16, Folder 15. The drawings fall into three broad categories: Flat drawings (generally 24" x 36" but some smaller and larger) organized by "groups" (e.g. Boiler Building and Equipment, Group 3) and organized thereafter numerically by a drawing number (e.g. 62). In some instances not all drawings from the orignal indices exist and therefore are not present and some numbers were not used. When possible, the processing archivist noted if a number was not used and where drawings are "missing." The small drawings are designated numerically (e.g. 3-1, Steam, air and fresh water lines) Drawings that are colliery specific have an alpha numeric designation (e.g. CR-#A, Pumps). The latter also includes correspondence with other companies that provided equipment or services, proposals, estimated cost sheets, purchaing orders, work orders, agreements, trade literature, bills for materials, and proposals.
