In this way the efficiency of the steam can be increased fully ten per cent. "When it is possible to carry the con- densation back to the heating plant at a temperature of 150 degrees, as may be done when the distance is not great and the return pipe is properly in- sulated, this permits a considerable saving of fuel, as compared with the cost of raising the temperature of well water from 50 degrees to 212 degrees. We are told that it requires the ex- penditure of 967 degrees to form steam from water at 32 degrees, and on this basis, while approximately 950 degrees will be required to turn well water at its usual temperature into steam, only 850 degrees will be required if the water has an initial temperature of 150 degrees, and still less if it is returned at a higher temperature. On this basis an allowance of ten per cent, less any increased cost for returning the water, might be made, as compared with the cost when it is turned into the drains. A Nebraskan's Example. Acting on advice obtained through the Greenhouse Heating department of The Kevicvv in 1919, F. J. Ayres, of David City, Neb., now uses this method of heating his houses and pronounces it "sure a ; The houses heated include a main house, 34x100 feet, with a walk down the center across the width. On each side of this walk are six benches, forty-six feet long and forty-two inches wide. Joining this main house is a small house, 18x76 feet, where ground beds are used. Against the walls of botli the main house and the small house is a small service house, 18x24 feet. This makes, practically, a house 100x100 feet square, having a glass area of about 5,000 feet. He secured a 15-year contract with the city cou
