It is therefore impos-sible for a motorman to coast to a standstill and obtain a fictitious record because the energy which operatesthe clock magnet ceases just when the motor stops. On a straight-air-brake car the relay is installed atany convenient place, but where hand brakes are usedexclusively the relay is installed under the car. Acommon method of installing the relay is shown below. Another merit of the new scheme is that the clocksoperation does not require any line current, which is an economy of some impor-tance on systems wherehundreds of clocks arein use. SPITTING ON THE FLOOR. PLATFfHtMSOS OTHER PARTS OF THIS CAR IS UNLAWFUL. OFFENDERS ARE LIABLE T(T AIRES! Order of the Soardef Recorder Reversed and Used asHealth Sign IMPROVEMENTS IN REC-ORD STRIPS AND CASES The original form oftape record showed onlythe motormans numberand his coasting was found that motor-men would retain badrecords until they couldhand them in with theexcuse that the recordhad been spoiled by someblockade. The new formof record shows not onlythe motormans numberbut also that of the car on which the record was motorman will not dare to hold this record backbecause other men might turn in records with thesame car number at the same time. A most valuableby-product of the car number record is that the coast-ing efficiency of the cars themselves may now be com-pared. In fact, several companies keep coasting recordson both the mechanical and human bases, so that theycan now detect inferior running equipment as well asinferior men by the same means. The tape on which the record is made was originallyof one shade, white, throughout. Now the last 20
