The motor wasstarted April 9 and has been running with satisfaction since,even under the most exacting service that the road demands. AUTOMATIC LUBRICATION. A liberal supply of oil fed automatically to the workingparts of an engine, contributes wonderfully to smooth, quietrunning, and relieves the engineer from the drudgery ofwatching and re-filling a lot of oil cups. The cut illustratesthe system applied to the American Ball engines now build-ing at Bound Brook, N. J. The characteristic features of this system include a posi-tive circulation of oil from an external storage tank intowhich the oil is strained on its return from the engine frame,and an entire separation of the water from the oil, by meansof a tight bulkhead near the cylinder end of engine SIDE VIEW OF ENGINE. A simple pump placed in the storage tank, and actuatedfrom the rock shaft, circulates the oil through suitable pipesand discharge nozzles, to the stationary working surfaces,from where it flows by gravity or centrifugal force to thecrank pin and cross head pins throughoil holes and channels,provided for that purpose, and thence by gravity back to thestorage tank, on entering which it passes through a fine gauzestrainer located in the tank. To insure an abundant supply of oil at the discharge noz-zles, the pumping capacity is made to exceed the maximumrequirement, and the surplus oil escaping through a reliefvalve falls back into the storage tank. To provide againstpossible derangement of the pump, a gravity receptacle isis arranged to be instantly attached to the system, as anemergency supply. The reports of the receiver for the Metropolitan Eleva-ted Railroad, Chicago, show that from January 20 to Feb-ruary 28, the number of passenge
