Descriptions of Oyster Survey Signals, State of New York (600 pages, not all of which are used) is a two-volume survey of signals located along the north coast of Long Island in the 1880s. Each volume is 300 pages long and has a title and the names of Eugene G. Blackford and W. G. Ford., Jr., stamped in gold on the front cover. Together, the volumes comprise a survey of many oyster signals, arranged alphabetically by name.
Most descriptions are dated 1881-1887, but the commission revisited some signals as late as 1892. Each entry contains a detailed description of a signal's location and composition (painted poles, flags, etc.). Some entries note the signal's distance from nearby towns or its location along bays and inlets. Manuscript maps and drawings of signals and their locations are present throughout the volumes. Descriptions are attributed to various persons, including J. P. Bogart, G. Bradford, W. C. Hodgkins, Charles Hosmer, I. C. McCorkle, J. A. Sullivan, C. H. Van Orden, and Charles Wyeth. Each volume contains a print of a tripod signal topped with flags.
