CLAY DEPOSITS.
An Important Investigation To Be Made
BY the Geological Survey.

The Maryland Geological Survey has be-
gun an exhaustive study Of the clay de-
POSTS of the State. Prot William 3.
CLARK, the State Geologist, has recently
secured the services OF Prof. Heinrich Ries,
Of New York, the leading clay expert Of
this country who will make thorough in
vestigation OF ire properties and posi-
bilites of the clays of Maryland. Pro
fessor Res has been frequently retained by
the United States Geological Survey and
important industrial interests to look into
the various clay products of the country.
He has also spent much time in al ex-
haustive investigation OF she clay industry
of Europe, so that he is fully informed
upon this very important snhisc..
The clay industry of Maryland is already
of considerable magnitude, nearly 81, 600
600 OF clay products of various kinds being
produced within the limits Of the State
each year. These clays have great variety
OF uses and have only been partially ex.
plotted hitherto. There is no reason why
under proper Investigation the clay in
dustry should not be greatly expanded.
The Maryland Geological Survey has been
gradually preparing the way for the publ
cation OF an elaborate report upon this
subject. Such q report was prepared some
years since By the State Geological Survey
Of New Jersey, and has been the basis for
very extensive development of the clay
industry in that State, and the volume is
regarded by clay workers generally as a
work Of much value.
Professor Ries spent much OF the month
Of March in a provisional examination of
the central clay belt Of the State from Ceci!
across Hartford Baltimore, Ann Arundel
and Prince Georges counties. He selected
about one hundred samples OF different
types Of clays to be submitted in his
laboratory to careful physical and chemical
tests. Professor Ries will return again in
June for several weeks further investiga-
ton OF the clay deposits, and will COM
DleEe His uelu WOllA ny huSuLuh'
Few sections Of the State are without
clays of greater or lesser value. Many of
these clay deposits have already proven
useful in the manufacture of ordinary
brick, friedrich, gas retorts, stove Innings,
terra Gotta, roofing tile, stoneware cement
mineral paints, ETC., while many others
have not yet been exploited, so that the
possibilities in this industry are still very
great The chief centers Of developments
are the region about Baltimore, Central
Cecil and Western Allegany counties,
where successful industries are now in full
operation.
''The Maryland Geological Survey has,
during the last few years, been mapping
the distribution Of the various clay forma-
tons, and after Professor Ries has thor
oughly determined the uses of the various
types report of much value to the various
commercial interests OF the State can be
prepared. Many formations yet undevel-
oped will be described in this report It
will probably be year at least before She
detailed physical and chemical tests can be
completed and the report written and
printed. Professor Ries will prepare for
She volume full discussion OF the tech
nology and properties of clays in general,
with special application to the various
olays represented within the limits OF
Maryland.
