John Benbow, Jr., of Cowley Hall Mills, Middlesex, England, was an avid amateur beekeeper in the 1840s and 1850s. His "Bee Book" is a small (16mo) copiously illustrated treatise and journal of beekeeping. Divided into three parts -- "Other people's experiments," "Our own experiments," and an annual log (1846-1854) -- the book includes information on hive construction, seasonal management, the cleaning of hives, and other miscellaneous information culled both from printed sources and personal "experiments." The 44 pen and ink drawings include technical drawings of hives and beekeeping apparatus, along with humorous sketches of the activities of an "amateur apiarian."
