Q. Can a pump be got that is workable by one man to draw water from a well 100 feet deep; and, if not, what is the greatest depth such a pump will draw, and where obtained?

A. The pump-bucket must not be more than 20 to 25 feet above the water, in order that the pump may draw. A pump can be made with the foot-valve and bucket 80 feet below the surface, but it would take a pretty powerful man to work it, for at every stroke he would have to lift a column of water 80 feet high of the diameter of the pump-bore.
