The low readings on the seventh point are partlyaccounted for by a very slight favoring grade.

The Electrical Engineer commends to inventors thedesigning of an electric car speed indicator, which wouldenable the motorman to tell the speed of his car at a

tice the controllers are never stopped long on any but thethird and tenth points. There are also variations whichcome in to influence results, and which are most difficultto account for. This is shown by the record of the speedsduring the above readings, which were as follows: First glance, and so tell whether he is violating the city ordin-ance as to speed. That it has become a necessarj^adjunct for electric cars is obvious, says the Engineer.We always had the impression that a motorman whocould not tell how fast he was running within two or 148 ^lA£d.j\mWa^j^A/lcv/ three miles per hour ought to be taught better or fired.Fine distinctions are not necessary, and as a competent mancan determine very closely his car speed, what is theuse of putting such a plaything as a speed indicator ona car. If the schedule time is too fast, danger of acci-dents will be increased. The maximum speed has verylittle to do with it. It is the temptation to sacrifice safetyfor time and take risks that wou
