SOME COAL FIELDS.
Report BY the United States Geological
Survey.

Survey.
Washington, D. G.. July 9.-some Of
the most important western coal fields
that nave been examined and mapped Ply
the geological survey in the course q
II work Of classifying the public lands
are In Colorado. The survey has Just
issued. a. bulletin 4l5, a report by Hoyt
IS. Gale on the coal fields OF northwest
ern Colorado and northeastern Utah.
Large Areas Of Public Coal Lands
Large parts Of the areas described by
Mr. Gale are still public lands, for o.
the region examined is somewhat remote
from railroads II Is az yet rather sparse
liz settled The valley Of the upper
Yampa river is now reached by the
''Mohat road, which was completed as
far as Steamboat Springs about year
ago II Is reported that this road VIII
soon be continued westward and is pro-
posed route Is shown on the maps IN
this report. The report also gives de.
scfptions and unbiased estimates Of the
most important resources Of the coun-
trv adjacent 70 this new road for a disc
lance along its route OF over 100 miles
and Is therefore particularly timely and
interesting.
New Maps.
The bulletin contains rne new topo-
graphic and geologic maps which are
similar IN form TO the geological sur
vey's topographic atlas Sheets al.
though not complete nor final as com
pared with the surveys standard maps,
they probably win be ror some time
The best available maps Of the areas
they cover.
Description Of the Coal Lands.
The report describes the general geol.
ogv Of the region and points out the re-
lations of the coal. bearing rocks to the
other strata in these fields and in the
adjoining areas. Each area that Is like
liz to be developed as a large CONNER.
cial field Is described separately. The
descriptions follow the public land sur
vey units that IS, they are given IN
order bv townships, with references to
sections and areas within townships.
Most Of the data showing the number
and thickness OF coal beds were obtained
at prospect openings. Sufficient in-
formation has been collected 70 prove
beyond doubt the great value Of these
lands and to afford general estimates Of
the amount Of available coal they con
tain.
Quality Of the Goals.
The bulletin includes table showing
the results Of " analyses Of representa-
tive samples OF the Goals These sam
pies were collected in the course Of the
survey Of the field and were analysed in
the governments laboratories. The ta-
bic o. analyses Is 10 arranged as To per-
nit ready comparison Of Goals from diff.
ferent parts Of the areas described The
analyses are accompanied by a brief
discussion Of the meaning and interpTe-
tation Of analyses Of coal and q general
estimate Of the quality Of the Goals in
these fields
The greater part Of the best coal in
this general region may be elassei as
high-grade bitumn0us The coal from
few districts shows a higaer calorihe
value and that from others must be
classed a. suhbtnminous OF Ignite. The
a,h Is normal, ranging from 5 TO 10
per cent; the percentage Of sulphur Is
low Most q the Goals are high Ia yola
lilo coauhustible matter. 80 that skilled
firing and efficient furnace construction
are needed to produce the best results.
