=13.= At the present time, most houses that are as large as the one
under consideration are equipped with electric door bells, and probably
with electric bells from some of the living rooms to the kitchen. Such
an equipment would cost, say, $25.
In most houses of this size, where available, both electricity and gas
are used for lighting purposes. The cost of wiring this house complete
for electric lights, including six wall switches, besides two three-way
switches for the hall light, so that it can be operated either from
the upper or lower floor, is about $325 if iron-armored conduit is
used. If electric lights are used, the lighting fixtures must be
combination fixtures, that is, fixtures that can be used for both gas
and electricity. This will add about 40 per cent. to the cost of the
gas fixtures, or 40 per cent. of $316.75, which amounts to $126.70.
The total cost of wiring is therefore as follows:
Electric bells $ 25.00
Light wiring 325.00
Extra cost of fixtures 126.70

Total $476.70
