"Fourth-To elaborate a system or network of
conductors capable of being placed underground
or overhead, which would allow of being tapped
at any intervals, so that service wires could be
run from the main conductors in the street into
each building. Where these mains go below the
surface of the thoroughfare, as in large cities,
there must be protective conduit or pipe for the
copper conductors, and these pipes must allow of
being tapped wherever necessary. With these conductors and pipes must also be furnished manholes, junction boxes, connections, and a host of

distribution.
"Fifth-To devise means for maintaining at

from the central station, should give an equal
light at all times, independent of the number that
