VIEWS OF CAliLE ENGINE TO BE REPLACED HY ELECTRU MOTOR. largest electric motor running in the world, but there isno reason to believe that it will not do its work exactlyas expected by its installers. It will be shunt instead ofcompound wound, because shunt winding is the simplerand will keep the speed within a two per cent variation,which is as near as the steam engines now keep it. The use of this motor will offer a splendid opportunityto study the variations of power required by the cable. It will also be possible to tell much more closely thanever before the per cent of power required to move thecable without cars. The difficulties of taking engineindicator cards quickly has always been in the way ofstudying closely the performance of cable machinery,but this difficult}- will disappear when an ammeter is sub-stituted for the indicator. The saving in labor alone due to the change willamount to $28 per day. The electric plant will requireno additional force, while that in the cable
