Issues New Bulletins
On Coal and Oil

New bulletins have just been issued
from the press by the State Geologi-
cal Survey at Urbana on the Coal
Resources of Western Illinois, Coal
Losses in Illinois, the significance of
carbon ratios in regard TO the occur
renee of oil and gas and proper meth.
ods of testing for oil structures with
citation of some areas deserving eueh
testing.
The report on The Coal Resources
of Western Illinois by Harold r..
Culver, covers an area of about H.
900 square miles comprising all o.
parts of the following counties
Adams, Brown, Calhoun, Henderson,
Henry, Jersey, Knox, Madison, Mason,
McDonough, Mercer, Morgan, Pike
Rock Island, Schuyler Scott, Warren,
and Whiteside. This aistnc, Is known
as District 3 of the Illinois Mining
Investigations. There is "A total of
eight districts, and reports have now
been prepared On all of them This
bulletin may be obtained on payment
of twenty-five cents IN postage or cur
rency, and is known as Bulletin q
of the Cooperative Mining Series.
The bulletin ON Goal Losses IN Hi.
nois" VISA authoritatisely written b>
the late c. A. Allen, and deals Will
the Losses involved @in. the preseni
methods of mining coal in Illinois
All the principal coal mining districts
of Illinois are included. Problems in
velving surface subsistence ard mine
labor are not included. The report
comprises 30 pages, is kown as Bulle-
tin 30 Of the Cooperative Mining
Series, and the price is twenty cents
in postage or currency
Because petroleum Investigations In
Illinois are greatly hampered by the
occurrence of the thick cover of
glacial drift and the shallow erosion
of the surface, the geologists IN study
ing the possibilities of occurrence of
oil and gas must consider every nossi-
Bile line of evidence. The repols which
has been issued on Carbon Ratios
and Petroleum in Illinois, by Gail r.
Moulton, is known as Report of Ia.
vestigations No. 1. 1t defnes what
Is meant by carbon ratios, presents the
data obtained from a study of the
large number of coal analyses in the
possession of the State Geological
Survey, points out the relation Of he
oil sands TO structural featurs, the
relation of the character OF the coal
TO these structural features, ami pre-
sents certain conclusions concerning
oil possibilities in different part OF
the State. The price of the report IS
twenty cents in postage or currency.
The report on Proper Testing for
Oil Structures in Illinois and some
Areas deserving such Testing by Cal
+. Moulton Is known as Report Of In
yestigations No. 8. II outlines Ihe
most satisfactory method of exp'Or-
ing for oil in Illinois and calls a''e7-
ton to some of the areas which are
worthy of testing. 1t also contrasts
the high cost of erratic deep drilling
with the moderate cost of systematic
shallow drilling, followed by one OF
two deep tests, from the standpoint
of both expense and definite results.
The price of the report is TIVE liy
cents in postage or currency.
A fifth report is just about t. be
issued from the press on Further
Contributions 10 the Geology Of ;hc
Allendale Oil Field with q revised
structure map. 1t not only includes
the tract north Of Allendale, which
has recently been the site of the dis
covery Of large wells, previously
recommended BY the State Geological
Survey in one of its bulletins, but all
the AIlendale field. Oil operators an
others interested in this publication
should ask for Report Of InvestiRa-
tions NJ. by Gail F. Moulton. The
price is twenty cents in postage or
currency.
All the above mentioned bulletins
are obtainabe at the prices indicated
