Sprinkling of Any Kind of
Coal on Wood Fire Will
Keep Efficiency.

Hartford, Feb. 11-Economical and
efficient methods of burning wood in
in a coal furnace are described in
brief series of directions which has
been prepared by E. H. Lockwood,
professor of mechanical engineering
at Yale University, for the committee
of fuel conservation, Connecticut
State Council of Defense.
Professor Lockwoods Directions
for using wood in coal furnaces fol-
low:
The simplest way to use wood in
coal furnace and the most effective
in producing heat is by using a COM
bination of wood and coal. Any kind
of wood can be used that will go into
the fire pot-hard or soft, large or
small-and will burn with good eff
cheney when surrounded with coal. In
stead of shoveling on coal in the
usual way, place blocks of wood on
the fire to about the level of the first
door. then add coal on the top which
will fill the crevices between the
wood, making a level fuel bed with
the coal on top. Any size of coal or
coke can be used but the small sizes
fill in best between the chinks in the
wood. Buckwheat coal can be burn
ed successfully in this way and It's
low price will help to offset the higher
price of wood, making an economical
combination. From rs to so per cent.
of the coal can be saved by substitu-
ton of wood in this way.
the small
sizes of coal take care to avoid gas
explosions by always leaving a lame
burning on some part of the fre-ln
other words, do not cover the whole
fire with fresh fuel at one time.
To Use Wood Only.
The best form of wood is short
sticks eight to IL inches long, pre-
ferabIy hard wood. The best method
of firing is to keep the furnace full of
blocks packed closely together with
a moderate draft to give the desired
amount of heat; as the wood burns
more should he added in order to
keep the deep bed of burning fuel
which is best for economy. 1t is not
necessary to buy new CRATES for
burning wood although the ordinary
coal crate is not we'll adapted for
wood. Banking a wood fire at night
requires an extra supply of the larg-
est blocks and special attention to
closing the hampers tight. Exper-
fence will show the best way, but it
can be done with success in most fur
naces.
Wood In Fireplace.
Where a fireplace is available, wood
can be used to good advantage as
supplementary to a furnace or even
to replace the furnace in fall and
spring with decided economy. Few
persons know that a wood fire can be
kept burning night and day in fire.
place with very little attention and
with small consumption of wood. Any
kind of wood can be used provided it
is dry and seasoned. The secret OF
fireplace management is plentiful
supply of ashes which should be kept
at the level of the andirons. AS the
blocks burn an accumulation of glow
ing charcoal forms by falling into the
ashes and this $keeDs on burning
slowly and assists ignition of fresh
wood placed on the andirons.
To bank a fire in the fireplace,
cover the hot charcoal over with a
thin layer of ashes and a fire Sc
banked will keep for 10 or IL hours
and will give out some heat from the
hot bricks all the time. A we'll man.
aged fireplace will be found a great
addition to the heating system in any
residence.
