COAL PRODUCTION
Of The WORLD
SOME INTERESTING FIGURES
COMPILED BY THE GEO
LOGICAL SURVEY.

WASHINGTON, Oct. .. The
worlds production of coal in 1906
amounted to about 1,106,476,707
short tons, of which the United
States produced 4~14,157,27S tons.
Since 1898, during a period of
twenty-nine years, the percentage of
the worlds total coal production has
increased from 1892 to 81, and this
country 10Y stands far in the lead of
the worlds coal producers. 1t has
been only eight years since the Unit
ed States supplanted Great Britain as
the leading coal producer, yet the in
crease in this country has been SO
enormous that Great Britain can no
longer be classed as a competitor. In
1906 the United States produced
43.7 per cent more coal than Great
Britain, and 50 per cent more than
Germany. Exclusive of Great Britain
the United States in 1906 produced
more coal than all the other coun-
tries of the world combined.
1t may also be noted that more
than SO per cent of the worlds pro-
duction of coal is mined in countries
north of the equator, the countries
south of that line contributing less
than 10000, 900 IONS annually.
Two classes of coal produced in
the United States are reported to the
geological suryey-anthracite and BIZ
luminous. The bituminous product
includes coal that may be classed as
semi anthracite, semi : bituminous,
camel, splint, and Ignite or sub-bi-
luminous.
In addition to the anthracite pro-
duced in Pennsylvania 54,40S short
tons were mined in Colorado in 1905
and 60,24S tons in 1906. New Mex
leo produced 24,415 short tons of ana
thraeite in 1905, but reported none
in 1906.
Semi-anthracite was reported from
Pennsylvania, Colorado. Indian Terri
tory. Virginia. Montana and Arkan-
sas.
Bituminous coal was produced in
twenty-seven states and territories in
1905 and in t~wenty-four in 1906,
and forms by far the largest part Of
the total production.
Semi-bituminous coal is mined in
seventeen states and territories, with
West Virginia first. followed in order
by Pennsylvania, Maryland, Illinois.
Virginia and Montana.
Wyoming leads in the production
of Ignite or semi-bituminous Goals
over 40 per cent of the production OF
the state being so classed. The so.
called black ignite of the Rocky
mountain states are entirely distinct
from the real lignites or brown Goals
They are not lignites in chemica
composition. in color, or in physica
characteristics, and as they lie be
tween the lignites or brown Goals
and the true bituminous has beer
adopted by the United States geo
logical survey to designate them. II
the production of this variety of oca
Wyoming leads, Colorado is second
and New Mexico is third. A part o
the product of Oregon and California
should also be included under thi
head.
The principal producers OF tru,
Ignite, or brown coal, are Texas an,
North Dakota.
The comparatively small produc
tion of camel coal was obtaine,
from nine states in 1905 and sever
, in 1906. of which Kentucky, Indians
and West Virginia are the principa
ones. West Virginia is also credite,
with nearly all the splint coal produc
ton, while Indiana is the leading
producer of block coal.
