he fact that in order TO avoid the sefy

rical resistance OF the conductors, where
lumber of lights are required at a consider

ecessary to use conducting wires OF enor-

he fact that domestic and indoor lighting,
here incandescent lamps will be mainly
sed, is ordinarily confined to about sixl
ours a day on an average, and yet usuzllyl
