All of this work was done by the Safety InsulatedWire & Cable Co., of New York, under the supervisionof the City Electrical Department. Street LightingChairman Pococks prophecy that London would belighted as never before has been more than are installed at present 1,600-75 watt ampere. Brick lined Manhole, Showing Conduit terminals tungsten lamps complete with Wheeler reflector andmounted on the poles with side brackets about 17feet above the ground and spaced about 300 feetapart. The light distribution from these lamps ismuch better than with the open arcs, but it is furtherproposed to increase the amount of illumination by in-stalling additional lamps until spacing is 150 feet. Thissystem of street lighting is particularly advantageous inLondon on account of the great amount of foliage. The underground district will be lighted by eightyornamental posts, upon each of which is placed five tungsten lamps with Alba globes. These will be fed
