ray, OF this city, has prepared for
the TIMES, the following sugges-
tons for the consideration of house
wives and all burning coal:
Waste not. Want Not" About two
thirds of the coal bill goes up the
chimney or into the ash can. Take
heed to the following and two-.hirds
will be a benefit instead of a loss
The coal should be of such kind
that will give off the greatest num-
Der of units of heat. to meet the re-
quirements for which it is burnt.
The apparatus in which it is con-
sumed should be so constructed that
the draft. whether of ingress or
egress, can be under perfect control:
because the improper admission Of
air, whether of direction or quantity,
will prevent the perfed combustion
and thus reduce the number of B. T.
u. british thermal units) of heat per
pound of coal used it is therefore
very essential that the joints, seams,
and doors, be made as nearly air-tight
as practicable.
The fire pot or fire box should he

amount of heat required, the shape
of the wall. preferably round or if
rectangular or square, the corners
should be roundish.
AS to the troubles from smoke, poor
drafts and economizing extra heat. it
is best to consult an expert tinsmith
or furnace man, because they are

can point out the remedy.
1t is estimated that about one-third
of the coal used for fire is expended
in producing the draft and the residue
in ash and clinker; but this may be
increased 10 one-half when the APP
paratus has not been manufactured
upon scientific principles and me-
chanical skill or when improperly
installed or mismanaged. that is 20
say. assuming that there are from t.
600 to 1900 b T U. in one pound OF
the average quality Of coal with per
feet combustion and management, g.
500 heat units should be available but
if the reverse condition exists but
about 1900 of the heat units are uul-
lied. hence the importance of care
full study of the coal problem.
Hard coal does not require as large
fire pot or box as soft coal.
All surfaces that permit the radia-
ton of heat where not needed. should
be covered with some kind of non
conducts of heat material or surround
ed by still air.
To obtain the fall heat value of coal
it is estimated that about three hun
dred cubic feet of air, per pound OF
coal. varying in volume as to the
kind of cOaD should be supplied to the
burning coal.
The ash pan or pit should be kept
free from ashes, so that the volume
of air required will have space tC
enter and be slightly warmed ant
this also prevents the burning or thu
varying of the CRATE.
The CRATE so made as to be easily
shaken and to facilitate the withdraw
al of clinkers.
Reclaiming the coal that is dump
ed into the ash pan will amount tC
a pretty penny at the end OF the
month.
The coal bin should be built to pre-
vent dampness and forgetfulness o.
a borrowing neighbcr.
Much coal can be saved by BURNING
waste combustible material. wheI
fires of short duration are necessary
1t is good practice to sample by
burning test the coal before pu--
chasing a large supply, rejecting tina
which makes too much ash or clinkers
The sanitary condition OF the prem
Uses plays an important part in tn
economy of coal as well as of life
every grammar school child know
that the breathing of pure air make
the body warmer than when foul al
is inhaled, and that more oxygen en-
tiers the lungs Intervals of time bein
the same) when cold air is breathe
than when it is heated.
strict obedience TO the hygeni
rules of living will enable the body
endure a very cold atmosphere with
out discomfort, and therefore Jesse
the amount of coal required for al
heating purposes.
