Company, Crestline, Ohio,which is especially suited to replace the common water liftto pump rain water for soft water in residences. It canalso be used for general water supply in homes when citywater supply service is not available and the pump can beplaced so the suction lift will not be over 25 feet. The outfitis made in two capacities—Model A single cylinder with acapacity of 125 gallons per hour, and Model B, with a capa-city of 250 gallons per hour. Both will operate against apressure of 50 pounds per square inch. automatic con-troller switch is connected with the discharge and is set to. operate between pressures of 40 pound maximum and 20pounds minimum. It can be adjusted, however, to operateat any desired pressure. The pump gears run in oil, and thissame oil is automatically carried to all the pump only oiling necessary therefore, is to place one quart ofoil in the oil chamber on starting. This will be sufficientfor one years normal service. The cylinders are brass lined,have a 1^-inch bore, 3-inch stroke, and are self-primed. Anair valve provides sufficient air for pneumatic pressure tanksystem. The valves are bronze and rest in bronze seats. Thepump and motor are mounted on a cast iron base. The pumpis a slow speed type which is connected to the motor bybelt with idler pulley attachment. Pressure tanks are alsosupplied when ordered. Model A is fitted with a 1/6 horse-power, and Model B with a J4 horse-power Robbins &Mvers motor. A Fine Lighting Scheme One of the most interesting features in connection withthe new Toronto
