Otherwise, heavier wire may be required; 
and this means greater expense. When 
the battery needs recharging, the current 
supplied must be of at least as high volt¬ 
age as the battery. By using a current of 
considerably higher voltage it will be pos¬ 
sible to cut down the time of charging. 
If we know the total watts required for 
the entire group of lamps we will be in 
shape to select a proper battery. Sup¬ 
pose, for example, that there are 18 16- 
candle-power tungsten lamps and 12 8- 
candle-power lamps. The total candle- 
power required will be 384. As 1.25 watts 
are required per candle-power, the battery 
must discharge a current having the 
energy of 480 watts. If we make use of 
the fact that watts divided by volts give 
amperes, we readily find that the battery 
should have a capacity sufficient to enable 
it to discharge current at the rate of 15 
amperes (480 -f- 32) for whatever num¬ 
ber of hours it is proposed to operate the 
lights. 
The Choice of Domestic Hardware 
(Continued from page 17) 
the choice of hardware ought to be made 
by studying its fitness for each individual 
place it is to appear. From numerous 
illustrations and reading anyone with a 
fairly observant eye and attentive mind 
may readily recognize the characteristics 
of the hardware belonging with the several 
architectural types, and will then be in a 
position to make a wise choice, keeping in 
mind the general principles previously set 
forth. It is manifestly impossible to say 
of one piece of hardware that it is bad or 
good without reference to the place it is 
meant for, unless its design or structure 
be uncompromisingly inferior. 
In conclusion, a word must be said about 
the available sources from which to make 
a choice. We turn naturally to the archi¬ 
tecture of the past for present inspiration, 
and so it is also in the case of hardware. 
It would be impossible, of course, to find 
any sufficient supply of old hardware, even 
were it desirable. A certain number of 
old pieces are just as good now as when 
they were made, but most pieces bear irre¬ 
parable marks of wear. The old hard¬ 
ware, however, can be most valuable in 
supplying us with models and standards of 
design that may either be copied or judi¬ 
ciously adapted to present needs. For this 
new hardware we may either employ the 
labors of the craftsman — and there is no 
place in which a little of the craftsman’s 
skill will show to better advantage — or we 
may make a selection from the stock of the 
manufacturer. Some of the latter, while 
structurally excellent, is purely commer¬ 
cial in appearance and of unmitigated Vic¬ 
torian banality of design. A great deal of 
it, however, is of excellent pattern, and by 
a little care in selection one may obtain, 
from a wide variety of possibilities, thor¬ 
oughly satisfactory results at an extremely 
moderate outlay. 
Hardware 
S UCCESSFUL architects specify Sargent Hardware for door 
and window trimmings because they know there is a Sargent 
Design that fits exactly the architectural scheme they have in mind. 
Accuracy of design and quality of workmanship are bringing more 
and more architects and builders to use the Sargent line for every 
detail of hardware trimmings.
