. Report of the Electric Railway Test Commission to the president of the Louisiana Purchase Exposition . re-corder was calibrated in position by jacking up the car with thetruck in position, and rvmning the wheels at different speeds,simultaneous readings being taken of the revolutions of thewheels, and of the indicating gage of the recorder. At thesame time a record was taken on the tape of the recordinginstrument. In working up the speed curve the Boyer rec-ord was plotted to a larger scale and integrated between streetintersections. The average speed thus obtained was checkedby the distance traversed, and by the elapsed time, as shownby the other data. After having made certain that the distance-speed curve wascorrect, it became necessary to change this over to a time-speedcurve. This was done by first laying off on a time base the ac-tual time at which the car passed the farther crossings of streetintersections, and also the actual time of start and stop wherestops were made. The various loops of the distance-speed curvewere then divided into a number of sections, and these sections.
