In theCutler-Hammer system of control the force of the inductive re-action, incident to the opening of the circuit, is minimized byhaving a discharge resistance automatically shunted across themagnet terminals just prior to the opening of the magnetic cir-cuit, this resistance being disconnected automatically prior to there-establishment of the magnetic circuit. These lifting magnets are furnished in any size from 10 to 50in. by the Cutler-Hammer Clutch Company. Milwaukee, Wis. 480 AMERICAN ENGINEER AND RAILROAD ELEVATIONS AND SECTIONS OF TEN-WHEEL OIL BURNING LOCOMOTIVE—SOUTHERN PACIFIC CO. TEN-WHEEL PASSENGER Pacific Company. The Baldwin Locomotive Works has recently completed anorder of twenty ten-wheel locomotives for the Harriman Lines,which have been consigned to the Southern Pacific locomotives are equipped for oil burning and are theheaviest and most powerful of this type on our records. Theyweigh over 203,000 lbs. total, of which nearly 160,000 lbs. is ondrivers. This gives an average weight per axle of 53,250 lbs.,which is unusually large for a ten-wheel locomotive and is abovethe average modern locomotive of any class. The greatest weightper axle of any locomotive on our records is 58,600 lbs. and theprevious maximum for ten-wheelers is 51,333 lbs. It will be remembered that in 1903 the Harriman Lines adopteda very complete set of standard designs for locomotives,* whichincluded designs for Atlantic, Pac
