The change of opinion among engineerson this subject, however, comes a bit late, as many of thecountries in which electric street railways have been builthave already adopted the trolley wheel, and further exten-.

The slotted-conduit system (with complete metallic cir-cuit) has been found satisfactory, but is only used in largecities where the traffic is very dense,where the difference in cost between itand a modern, first-class trolley con-struction is but slight, and where theinstallation may be expected to payinterest.
