Other and more extensive tests of the highpressure fire-service in Manhattan were made on Thursday last at West street, between Bank and Gansevoort streets, before a large number of interested spectators. At one time 28,000 gal. were thrown from thirty-two streams at pressures ranging from 90 to 175 lb. to the square inch. Four special water wagons, with pipes attached, and a water tower were also tested, with satisfactory results, A vertical stream of 150 ft. was obtained, and a horizontal stream of over 200 ft. The system tested was designed to supply protection to the district from City Hall to Twenty-fifth street on the North river and east to Second avenue and East Broadway. It consists of about 63 miles of mains from 12 to 24 in. >n diameter, and two pumping stations—one near Gansevoort market on the North River; the other, at Oliver and South streets on the East River. In each of these stations are five pumping units comprising Allis-Chalmers multi-stage centrifugal pumps, each driven by an Allis-Chalmers inductionmotor. The pumping stations can take water either from the city mains or from the rivers. The w-ater is pumped into the high-pressure mains at a pressure of 300 lb. to the square inch. Each pump has a capacity of 3,000 gal. a minute. The water was delivered through 3-in. highpressure hose, of which 14,000 ft. were used at this trial. Eight special Smith hydrants were used, with special holders for the nozzles. There were present many city representatives from Boston, Chicago and other places, all of whom seemed interested in the tests.
