yLw Gas STovE.-Cookng by gas has, for few
vss,s past, been considerably used in hotels and
rsaursnts but, for the want Of sufficient scientific
knowledge generally displayed in their construction,
but few stoves have been sold for family There
il 10 practical difficulty in constructing gas stove,
which will warm a very small room IN Winter or do
the cooking for a family in Summer, more convep-
ienty and economically than the coal stove or range,
for the reason that perfect combustion may be In

CURED But for heating large rooms or where both
heating and cooking required, az in Winter with
.devifed plans for burning other fuel is far
more economical. The fact that all our gas ia eI-
trscted rom COAL leaving a large proportion Of its
conbnstlble matter in the form of coke renders the
assertions Of inventors that gas produces more heat
than the same expenditure in coal rdicnously anus
ing; at the same time, the advantages enumerated
are sufficient to insure the rapid introduction of an eff
Gent gas stove. The following is the inventors de-
scrption of a novel plan for the perfect combustion,
and convenient application Of heat from gas. lie has

the inventor, says:

experiments the fine sand TO be found upon every sea
