Text Appearing After Image: .:-m - MONTREAL PARK & ISLAND RAILWAY-STATION AT BACK RIVERPARK Wooden side poles are employed and the overheadmaterial is of the best. The lines of the road will be extended and new equip-ment will be installed, eventually forming one of the mostcomplete electric railway systems in Canada. . BY GEORGE T. HANCHETT. Three-Wire System. If we have a number of electrical devices, each requir-ing a certain current, and connect them in multiple with asource of supply, it is obvious that we must supply a lineof sufficient carrying capacity and suitable resistance todeliver a current sufficient to operate all of these variousdevices, which current is the sum of the currents of all thedevices. If we. limit ourselves to a certain loss of pressure,we thereby fix the resistance, and, therefore, the size of the..conductors which carry the current. Copper wire is veryexpensive, and while it is desirable to have a small loss ofpressure, it is also desirable to have as small a wire aspossible; th
