The collection contains mounted photographs used presumably by the Alameda County Schools Curriculum Materials Center and later by the Hayward Unified School District as a teaching tool. The photographs are related to three subjects: dairy farming, the Delta Mendota Canal Fish Diversion Facility, and cattle ranching in Alameda County. The photographs were presumably taken circa 1950-1959. Captions from the back of each photograph have been used in the descriptions.
