There are three principal heating
systems for all the year houses
steam, hot water and hot air. The last
named is the cheapest and least to be

The steam system il the most
widely used. ard in the last few years
has reached a remarkable state of
perfection. The old criticisms and the
old jokes about the Commuter who
wrestles with a furnace do not apply
to an up to date steam outfit. 1t
might be said hat this outfit takes
care of itself: it needs attention only
for a few minutes at night and morn
ing. II used to be necessary for the
householder or his wife TO run down
and up stairs several times a day to
regulate the hcat. Now the intelli-
gent steam plant responds automat-
ically to any change in temperature
and keeps the house AT the precise
degree of heat desired. II makes no
difference whether the outdoor Their

the house temperature remains con
slant day and night. Tho old steam
plant was a habitual knocker, but the
new one IL noiseless. Again. the old
fashioned radiators would squirt guam
cities Of vapor and water. to the
detriment Of rugs and floors, but the
ncw tangled radiator does not let a
drop of water or n whiH of steam
escape. These improvements indeed
seem quite miraculous.
The invention which makes such
things possible Is a brass bellows m
tanning a liquid which volatilizes with
heat. II is very sensitive and expands
