Great Britain normally produces
about 2T5,OOO,000 tons. The normal
domestic and Industrial consump-
tion of coal per year In Great Bri
tain IL 100 100000 tons. the rest OF
oreat Britain's production Is ex-
ported.
on the basis Of expert figures thal
IA barrels OF oil fuel are equal
to one ton OF coal, the world must
produce 5,i00,0O0.o00 barrels Of oil
per year In order to replace coa'
fuel with oil throughout the world.
The present production Of oil In the
world is only 55O.o00,o00 barrels. so
that the worlds present output OF
oil is only sufficient TO replace about
II per cent OF the coal. In other
words, II all tho oil produced In the
world were shipped n Great Britain,
1t would be insufficient to replace
the coal consumed In Great Britain
for domestic and industrial pur-
poses.
British Coal Supplic'--E,pansion In
Use Of OH.
II has been estimated that the
known available coal fields of the
world insure an adequate supply FOR
the normal needs Of me world Tor
the next 1000 years. This. ~ course,
does not take into consideration the
possih ilitics Of the discovery or vast
now fields which undoubtedly exist.
While Great Britains visible coal
resources constitute only approx
matclv i-2 per cent of the total
coal resources OF the world, Il Is es-
timatcd that with proper care ana
economy in working Great Britain's
coal should be sufficient for its re-
quircmcnts for the next 500 years.
AZ for oil, there is absolutely no
certainty as to available supplies
Undoubtedly large reservoirs Of 'oil
exist in the world which hayo not
yet been discovered, but no estimate
can be made In any field as to the
period OF exhaustion for that filed.
Already the navies OF the world 60
far toward consuming At least a
third OF the oil produced In the
world. In addition 10 this the CON
version and the construction OF oil
burning ships in tho mercantile ma
rincs of the various maritime ma
tions has led to further consump-
tion Of oil as fuel. Thus the eNpan-
sion in the use OF fuel oil is bidding
fair to rapidly outstrip its present
production.
Relative Efficiency ~ the Two Fuels.
Turning from oil to coal an aver
age ton Of British coal Is supposed
to have heating value OF IL 600 Brit
ish thermal units per pound, and
the average price may be takon ne
| t2 per ton. Baslng the price of oil
at &c per ton and tho heating value
| Of oil at $4,000 II. {. u. per pound,
wo find that oil as fuel cost twice as
much as coal
David Brownie. in a recent com
putation Of the relative efficiency ~
coal and oil az fuel. takes as a rca
ssnable and fair comparison under
moderately good attention so PEI
cent efficiency for oil and - IL
per cent efficiency for coal. This
gives one ton OF oil at $4,000 II. {. II
and so per cent efficiency COSTING
| &c, as against one ton ~ coal OF
$4,000 II. I. u. and 70 1-2 per cent
efficiency costing f2 per ton.
Mr.. Brownies lementary doduc-
tions are, therefore. that one ton OF
oil is equal in net heating value to
| 1.65 tons of coal. and 10 produce
the same amount of steam as from
one ton of oil at &c II would cost
$3.50 IL coal were used. In other
words. If. manufacturer wer,
