FOR A GEOLOGICAL SURVEY.
Plans of the Maryland Bureau for
the Present Season.

the State Of Maryland and the programme
is outlined as follows:
Work viii be continued in Western
Maryland this season chiefly in Garrett
county, which was nearly completed last
season Dr.. G. C Martin viii have charge
of the work there and VIII devote his at
/ tcntiOn to the study Of carbOniferous for
nations He will carefully measure and
/ locate those coal seams which have not
( been hitherto mapped Associated with
Dr. Martin in this work is n Allen
Stockton, who has undertaken the i'm
Portant task of preparing for the coal re-
port which viii be later fssued-a chapter
on the mining of coal in Maryland.
Messrs- Penniman and Brown. the we'll
known analytical chemists, of Baltimore,
have been engaged for some time in max
ins both chemical and ca1orimetric tests
of the coal collected at various points.
/ The Maryland Geological Survey pur-
chased some time since a CaIoTimeter OF
modern design which gives much more
accurately than a chemical test the
steam producing values of the coal treat
ed The great work entailed in making
/ these tests does not make It possible to
analyze the coal upon every property, but
typical specimens are selected from vari-
Gus points from each vein, and these
comparative tests viii be later published
in the report on coal
! Investigations in the Piedmont area Of
Maryland are under the particular direc-
ticn of E 3. Matthews. His work dur
ing the present season viii be mainly
confined to Hartford county, where he has
as his associate Albert Jchannsen. 4
thorough study will be made of the vari-
Gus geological formations. particularly OF
-,
Dr. Matthews viii also be engaged with
DR. f Bascom, of Pennsylvania, in ex-
aiming the section in Cecil county The
base map for the Cecil and Hartford coun-
try area has just been prepared, so that
the necessary topography is available for
the geological plating.
The work in Southern and Eastern Ma
ryland is under the immediate supervision
of D. G. B Shattuc]s, and will consist first
in finishing up the work largely completed
the past season in St Mary's and Calvert
counties, and also in the survey of Prince
George county and parts of lower Cecil
and Kent counties y. L Miller VIII act
as assistant to Dr. Shattuck, and viii
this week begin the mapping of the vari-
Gus formations of the Prince George
county area, among which are the iron
bearing gravel, valuable for highways, the
mari deposits, and the silica which has
been hitherto mainly exploited on the
PatUXent River.
The work of the highway division,
which is under the direction of Dr. H. F.
Reid, is rapidly increasing in Importance.
A. y. Johnson, the highway engineer, and
his associate. J. Vi orrison Harris, are al
most daily in the field in connection with
the improvements which are going on in
Hartford. Frederick, Prince George, How
ard. and other counties. They are in
close touch with the boards Of county
commissioners and the road supervisors,
who are coming to recognize the impor-
tant aid this bureau can render to the
highway interests of the State Messrs
johnson and Harris have Just completed
an elaborate survey for the Improvement
Of some miles Of highway in Hartford
county under the provision OF the Wool
sey fund They have prepared complete
specifications under which the contracts
are 20 be let, and, at the request OF the
Hartford county authorities, VIII super
wise the construction Of the Highway.
The highway division is also engaged in
making tests Of the materials used on the
CITY streets. 1t has been called on by the
authorities Of Baltimore, Cumberland, and
Annapolis in connection with this work
The survey laboratory is fitted with the
necessary apparatus for testing vitrihed
brick and rnacadam materials. The City
Engineers Department of Baltimore city
today submits all OF this material,
before contracts are let, to the highway
division. and the city is in this way fully
protected In its purchases, since the tests
employed ~ at once the relative wear
ing and -aGing qualities Of the mate
ria!s submitted Most Of the progressive
municipalities as well as foreign cities rec
Ognize the great Importance Of the tests
employed il determining the value Of the
materials submitted by contractors.
The highway division has recently es-
tablished a machine for determining the
value Of cements used in public works
There are great opportunities for decep-
ton in the sale OF this material, but when
tested with the apparatus recently con-
structed the relative values of the mate
rails submitted are Immediately shown
