The authority and history of mixing and selling toxic baits for vertebrate pest control, invested in the County Agricultural Commissioners within California, is described. This practice dates from 1917, when legislation prescribed rodent control as a function of the state’s Department of Agriculture. Various types of mechanical mixers, including concrete mixers, mortar mixers, vertical mixer-blenders, and grain mixers are described.
