HON TO SAVE THE COAL
IND STILL keep WARN

Philadelphia. September 14.-Var-
ious ways to save coal and still keep
warm are pointed out by General
Committee of the Anthracite Coal
Operators in a series OF suggestions
given out here on conservation of
the fuel during the coming winter
months. Briefly they are:
Start furnace and kitchen range
fires as late as possible. Forget the
first few cool fall days.
Raise window curtains during the
day TO admit sunlight. for that is
free heat. Dispense with awnings as
they shut out the sun.
Membership all doors and win
dows and put asbestos around all fur
naces. boilers and cellar pipes used
for heating purposes.
Reduce the horae temperature to
sixty seven degrees. Do not wait until
the mercury shows seventy four de-
grees before closing drafts. BY this
time that extra amount of coal will
have been consumed and wasted ac-
cording to all economic rules.
Bedrooms, where windows are
opened for the night or otherwise
should be shut off from heat. Use
blankets and feel better in the
morning.
Wear heavier clothing. This ma
terially saves body heat
Thoroughly clean SCOT from pipes
and boilers and do not mind doing
= little work in the cellar seeing that
window panes are tight and weather
stripped like the other parts of the
house.
Burn oil. wood, coke and bitumin-
Gus when possible. Use gas for cook
ing and heating. Gas lighting at night
aids in heating the home, stores and
buildings where used.
Use heavy draperies on doors and
windows for interior home decora-
ton. This aids in husbandry interior
heat supply.
Washington, D. c., September A.
With the same degree OF energy, en-
thusiasm and patriotism as mani
tested by the women of the United
States during the year in saving
sufficient wheat to feed all of the
allies. the owners of steam plants,
and the firemen can save in the
r next year forty five million tons OF
coal, and thereby reduce materially
the Threatened coal shortage. accord
ing to the United States bureau OF
mines, department of the interior
In the average steam plant, for
every hundred tons of coal burned

used in making steam. The bureau
CT mines declares that it is entirely
feasible to increase the average eff
ficiency of these plants from 81 to
81 percent, saving fifteen tons of coal
out of every 100 tons used. AS 300
100000 tons of coal annually are ne
cessary to supply all the steam plants
in this country, the same work could
be done with 255.0GO0OO tons, with a
saving of about 100000 tons.
Heat Goes Up Stack.
In the average boiler plant, ac-
cording to the statement of the bu-
reau. 25 per cent of the heat of the
coal is lost up the stack. That is
ont of everv 100 tons of coal burned
1.-THE heat of thirty five tons literally
goes up the stack. This loss, which
the bureau believes can be greatly re-
duced. is caused by the admission OF
too much to too little air to burn the
coal properly. 1t takes fourteen
pounds of air to burr one pound of coal
and this can be gagged by the use OF
proper apparatus, which is explained
by the bureau of mines in a pamphlet
just for the benefit of the firemen.
Using just plain, ordinary intel
ligence we can save a minimum OF
45.000.000 tons in a year." said Van
II. Manning, director of the bureau
yesterday. 1.-THE methods to be used
are easy and simple to understand
The saving can come through the
good will and steady honest effort OF
the fireman and the engineer and the
encouragement and appreciation of the
owner or manager of the plant.
All Powders Are Fakes.
There is no miraculous powder that
when dissolved in water and sprinkl
ed over coal, will make it give ul
more heat and produce more steam
All powders sold under such pretenses
are frauds. Also there are no patent
ed devices that, when attached to the
boiler, will automatically make large
savings without the effort of the fire
man or the engineer. Many patented
fuel saving devices have elements OF
merit, but they must have careful, in
telligent attention to do good work.
