geology. This report is a monogram
containing 544 pages, one map, and so
plates seven of which are colored.
This is by far the most important re.
port thus far issued by the geological
survey With the exception OF the
chemical analyses given in the last
part of the report, the work is entirely
that of the author. The report CON
tains vast amount of new informal
ton relative to the Building Stone
resources of Wisconsin This report
has not only brought before the people
generally knowledge of the value of
wisconsin stones, but has furnished
the architect and builder an Invalu.
able reference work on Wisconsin
stone. The investigations which were
carried on in preparing this bulletin
shows that the state possesses mex
haustlble resources of granite, of ten
or twelve distinct colors and textures.
equal in durability and strength to any
eastern product. This report likewise
emphasizes the value and importance
OF the sandstone and limestone de-
posits, giving all available data, re.
speeding their occurrence, texture,
strength and durability.
The information which is contained
in a report of this character is espe-
cially valuable, because the statements
made are unbiased and the tests are
reliable. This report is referred to by
builders. contractors and biologists as
the best that has yet been published on
the subject of building and orna-
mental stones. This report will in
still in the minds of the people of Wis
consin and adjacent states a higher
and more wholesome regard for the
value of Wisconsin building and orna-
mental stones when compared with
eastern and imported stones.
Our clays.
In similar manner to that in which
the building stones have been investi-
gated DR.. Buckley has taken up the
investigation of the clay resources of
Wisconsin. Since May, 1899, he has
visited nearly all of the brick tile fac
tories operating at the present time in
Wisconsin, about 100 in number. All
the clay banks have been carefully ex-
amined and the methods of manufac-
turing given careful consideration.
Samples of clay from 80 or 100 local
oh I
analyses of most of the clays have been
made by S. V. People, assisted by w.
S. Ferris. The first number of the re-
port on Clays and Clay Industries was
published six months ago. This part
of the report is essentially a summary
of the Present Conditions of the Brick
and Drain Tile Industry in Wisconsin
although certain chapters are devoted
to principles which are necessary to
an intelligent understanding of the
process of manufacturing clay wares
The investigation of the clays shows
that Wisconsin has numerous quaint
ties of clay suitable for the manufac-
ture of common building brick, terra

earthenware. There are also less ex-
tensive deposits that can be advan-
tageously used in the manufacture of
paving brick and other vitrified wares.
! The most refractory clays and shales
were found to be suitable for the man
ufacture of fire brick of moderate fire
resisting qualities. The very plastic
white kaolin which occurs in the
western part of the state has been
demonstrated to be admirably adapted
to the highest grades of porcelain. 1t
has also been suggested in this report
that the clay in that vicinity might be
used successfully with the mari oc-
curing in the eastern part of the state
for the manufacture of Portland &C.
ment This report on clays is really
one of the companion pieces to the re-
port on Building and Ornamental
Stones.
The second part of this report was
intended to contain the results of a
more detailed laboratory examination
of the claws. Owing, however, to the
unfortunate condition in which the
survey was placed by the action of the
last legislature the work on this sub
ject was postponed.
