While the reconstruction of San Fran
cisco Is the foremost topic Of public
concern in California, Site Mineralo-
gist Aubury has performed a public
service by issuing a bulletin from the
state mining bureau I'm which direct
information is given to all concerned
where to find within the borders of the
state building materials I'm vast guam
titles. The bulletin Is exclusively de-
voted to facts about the great deposits
Of structural materials In California
which are ready at hand for builders
and to which they can turn and find at
once economy and advantage I'm using
home products.
Hundreds of millions of dollars will
be expended I'm the next few years in.
the rehabilitation Of San Francisco
The cost will be materially reduced, as
the state mineralogist points out, by the
existence near by of practically all the
fundamentals that will be required.
The bulletin on structural materials
was prepared early in the year. and was
prompted by the need of information
when, as the mineralogist writes, 1.-The
great demand for building stones, mar
ble clay and other products, together
with the phenomenal strides made in
the various Industrial pursuits which
are to a very great extent dependent
upon the mineral industry of this state.
has created a demand for an official
bulletin wherein would be found de-
scription not only Of the developed but
also Of the undeveloped mineral re-
of thi- state.
AT this time the information will
prove to be very valuable as an adver-
tisement abroad of the fact that in
materials, as well as in pre-
cious and base matals, California is
very rich, and that within its own con-
fines 1t has all the essentials for pros
porous and continuous growth"
Stone of Many Glasses
The completeness of the showing may
be judged from the statement that 1.-The
field work was commenced in July, 1904.
The investigation Of the subject has
over large areas, as all coun-
ties in Californa, with one or two ex-
ceptions, produce or contain structural
or Industrial materials in commercial
quantities"
Again the state minerologist remarks:
California offers exceptional oppor-
tunittes to the investor, particularly in
the many mineral substances of eco
nomic importance. A large percentage
Of these materials is imported from
other states or foreign countries, even
though the raw materials are here not
only in abundance, but in many cases
of superior quality, and only awaiting
the capital necessary to develop them"
There is no question that the build
ing stone resources of this state have
now greater economic importance than
ever before. The emergency lends new
