The steam is so drythat outside of extreme cold weather the construction andheat of the stack hides all exhibition of escaping interesting application of steam is also made to oper-ate the brakes, which work upon all four of the brake is very prompt and powerful, and will stopthe car in a very few feet. Many people would at firstthought imagine that a highly skilled engineer would berequired to operate a motor of this kind, but such is notthe case, and ordinarily it is possible to select the engineersfrom the drivers and conductors, as the matter of instruc-tion is neither a long or serious undertaking. The engines are duplex, of high speed and of verygreat power. The motor car weighs less than the trail car whenloaded, and really makes less noise than the other cars. THE HEALY MOTOR. in diameter with a 6 inch stroke, and piston-rod and con-nections are 16 inches long. They drive directly on twowheels which are connected with the other two by steelroller chains on axle sprockets. For ordinary work asteam pressure of 160 pounds is amply sufficient and sel-dom if ever runs over 200, although the boiler is tested to300 pounds. The speed varies according to the conditions of trackand load, l^ut will easily make under ordinary circum-stances 15 to 18 miles an hour and the engines are capableof making if desired, 700 strokes per minute. Thedisposition of the exhaust steam was one of the most care-fully worked out features of the motor—as this has beenthe great objection to steam motors upon the streets—the sight and noise of escaping steam. Mr. Healey has wholly overcome this, and taken careof the exhaust by enlarging the pipe through which itpasses and changing the direction till every bit of sound which are drawn in the train.
