註釋"A water system that will provide a wholesome supply for family use, prove serviceable for farm use, be as nearly permanent as may be made, and cost the least has been one of the four principal utility problems of the average farmer. The aim of this bulletin is to give to farmers, county agents, and others basic information concerning sanitary and engineering principles underlying safe, serviceable and lasting water systems for farmhouses." -- p.
