Thespeed of the car was obtained by means of a Boyer railwayspeed recorder which was checked by noting the time of pass-ing certain points in the route, and thus the distance traveled 302 ELECTRIC RAILWAY TEST COMMISSION in a given time was also determined directly. An observernoted the time of making each stop and its duration, thus giv-ing data permitting of a comparison of the number of stopsand the number of brake applications. WORKING UP THE RESULTS. The data were first arranged in tabular form after correctionof the instrument readings by calibration, and from these values. To Brake Lever To Brake. Cyl-Gase: ^ To Tank G/k&e. @J=^
