Then by the use ofthe split-second hand he records the time that poweris cut off and braking began. By stopping the watchas the car stops he has the complete cycle. The motor-man may apply and cut off power several times beforehe starts to brake or he may apply and release hisbrakes several times before he stops, but by recordingthe time that each different operation is begun thetotal time consumed in acceleration, coasting and brak-ing can be readily computed. Voltage readings aretaken at certain definite points along the run, and allhigh or low readings are recorded with their properlocations. Of course, a more extensive record can be.
