dgoes through the dif¥erent streetsand avenues where the feeders arelaid. It shows the sections betweencircuit breakers (which are indi-cated in the drawing by the lettersC, B and H), each feeder thatsupplies current to the trolley, polenumbers, the points where thefeeders dead end and the exactlength of each feeder. This recordsthe amount of resistance to be over-come and the drop of voltage in theline at any given point. The feedtaps themselves are not shown, asit is generally understood that theyare cut in about every 500 ft. There is another very importantuse in connection with these plans,and that is in connection with trou-bles.
