There is only one way to keep a checkon the voltage in this respect and that is by the use ofthe recording voltmeter. One of the greatest factors in the economy of power,said the speaker, was the intelligence of the are too often left to their own devices and handletheir cars unskillfully and uneconomically. For example,they move the controller handle from No. 1 to No. 2 with-out waiting for the acceleration of the first notch, so onto No. 3 and No. 4, with the result that they might almostas well throw it at once over from the first to the last.

This wouldshow them exactly what they were doing, and wouldteach the men what the instructor would find it ex-ceedingly difficult to explain. The motorman shouldbe furnished with diagrams showing the connec-tions of motors and controller and should un- 150 ELECTRIC RAILWAY GAZETTE. Vol. XIII.

Many intel-ligent motormen saved current by coasting instead of run-ning their cars almost up to the point where they are tostop and then applying the brake. In the same way theyused the momentum of cars to round curves or switches,or at any points where there was resistance to the Baylor next spoke of the desirability of so arrangings
