6. An Ingersoll-Sergeant two-stage air compressor driven by compound steam cylinders. The steam cylinders are 12 inches and 22 inches in diameter with a 12-inch stroke, and the air cylinders are 12i inches and 18i inches in diameter with a 12-inch stroke. A vertical receiver 42 inches by 8 feet high is provided for use with the compressor. 7> A 50 H. P . suction gas producer built by the Otto Gas Engine Works. This producer is adapted-to burning anthracite pea coal, coke or charcoal. 8. An Otto gas engine of 23 brake H. P . capacity for use in connection with the gas producer. The cylinder is 10 inches in diameter, with a 19-inch stroke. I t is provided with a compressed air starting device, sparking generator, speed indicators and all other instruments necessary for testing gas engines. 9. A 15 H.. P . De Laval steam turbine direct-connected to a compound centrifugal pump. This apparatus will deliver 140 gallons of water per minute when pumping against a head of 500 feet. The turbine wheel and small pump runner make 23,500 revolutions per minute; the large pump runner makes 2350. T h e turbine is provided with condensing and non-condensing nozzles. 10. A hot blast heating system installed to heat the Mechanical Engineering Laboratory. This consists of a series of coils making 2800 feet of 1-inch pipe and a 72-inch fan draw the air through the coils and force it into the galvanized iron pipe, 36 inches in diameter, which distributes it to different parts of the building. The fan is driven by a small vertical steam engine. 11. A 100 H. P . , Allis-Chalmers Corliss engine, equipped with a suitable brake and other apparatus for making tests. 12. Several high-speed steam engines for testing and for driving other apparatus. 13. Several types of gasolene engines, ranging from 1 to 10 H. P . , for experimental purposes. 14. An automobile testing platform for testing automobiles. 15. A 10-ton electric crane, having three alternating current motors, for experimental work. 16. A Golden oil testing machine for testing lubricating oils and bearing metals. 17. A p p a r a t u s for tests relating to the transmission of heat through scale-covered boiler tubes with respect to the loss due to scale. The equipment now in the Mechanical Engineering Lab-
