This collection comprises the annual reports of the Director of the Agricultural Extension Service and his assistants and is bound by volume. These volumes survey the beginnings and progression of the State College of Washington (later Washington State University)'s Extension Service in agriculture and home economics. These books show the growth of the program and record its expansion into a cooperative organization working with chambers of commerce, bankers, and railway companies to render assistance to growing Washington urban and rural economies. These reports detail demonstration activities, education efforts, and in general represent the work of the directors and assistants who worked to modernize Washington State agriculture and the economy through cooperative efforts with communities and individuals across the state. These volumes contain abundant reports on topics including land clearing operations in Western Washington, livestock evaluations, and general 4-H club work across the state, as well as monthly reports of the service's expenditures, attendance, and efforts at extending the knowledge of the State College of Washington to the citizens of Washington State.
