A. S., West Point, N. Y., writes:

"I wish to supply my house with water from a spring 1,800 feet distant and discharging 600 gallons of soft and pure water every 24 hours. This spring is 172 feet above the ground floor of the house. What is the best method of piping this supply for culinary purposes, bathroom, water closets, and lawn sprinklers?"

[Nearly 10 years ago the late E. S. Philbrick answered a similar question in our columns substantially as follows: A ¾ inch cement-lined pipe should be used to conduct the water. The method of making such a pipe is fully described in Billings's " Details of Water-Works Construction." Care should be taken to cut the screw-thread so as to allow the ends of the pipe to abut against each other when screwed into the couplings, for if a gap of one-eighth of an inch or more is left the inside of the coupling it will rust and fill up the pipe.

If you must have a storage of water for sprinkling lawns or any exigency demanding a rapid delivery for a short time, make a small tank in your attic or as close to your house as possible, of a few barrels capacity, and draw your drinking and cooking water, not from this but by a branch tap from the main. Let the water enter the tank at the top and discharge the surplus by an overflow pipe into the open air. In this way the branch tap will never draw from the tank, but always direct from the source. Then put in a pipe from the bottom of the tank to supply the hose.]
