DISPOSAL OF FARM SEWAGE in a clean manneris always an important problem. The aimsof this bulletin are twofold: (1) To emphasize basicprinciples of sanitation; (2) to give directions forconstructing and operating home sewerage worksthat shall be simple, serviceable, and safe.

Care in operating is absolutely necessary. No installationwill run itself. Continued neglect ends infailure of even the best designed, best built plants.If the householder is to build and neglect, he mightas well save expense and continue the earlier practice.
