eighth annual meeting of the Amerl-

Use of revolutionizing cooking and
heating with gas.
Three types of the gas stove have
been installed in the auditorium or
the jefferson. Gas pipes have been
placed to feed the stoves and con-
nections will be made today that all
will be in readiness for the demon
stration and lecture at s:l5 o'clock
tomorrow night.
Adds TO Efficiency.
The public is invited to this session,
preliminary to the opening Of the
institute. and those who attend will
he shown something absolutely new
Briefly stated, the new appliances
which are being exhibited in opera

cial form represent three different
types. one the domestic cooking range,
another hotel broiler and the third
a room heater.
These appliances are radically dif~
ferent from those that are now in
common use operated on 4 principle
somewhat similar to that familiar to
all in the Weisbach mantle gas light.
The use Of the mantle instead Of the
plain gas flame has resulted in the
material increase in the efficiency or
gas lighting, and now for the first
time proof or m equal advantage in
the use of what is equivalent TO a
mantle in the gas stove seems 70 be
given. In the flame only does il differ
from gas light.
No Flame In Sight.
These new stoves instead Of burn
ing gas with the familiar blue flame
appear to be entirely without fame.

flame in glowing in much the saline
way as IL does in a white coal fire.
The princlpie underlying the stove
construction that gives this result is
very simple as 1t is merely an ex
tension OF the same principle that was
responsible for the production OF the
common blue fame gas stove.
This blue flame is the result OF
adding tar to the gas before II reaches
the burner without sucn previous air

more efficient.
Electric Fam Gives Air.
In the new burners applied TO
