gonite and Catalina Island travertine.
Marble is supplied by Tuolumne and
san Bernardino counties.
Structural material which has been
secured has been from different areas,
widely separated. The material selects
ed has been with view. of not only
showing the. superiority of cur build
ing material but the many different
counties which produce it
ARCH AT. ENTRANCE.
The arch is to have a height of %
feet and a width Of 17la feet, with.
thickness of 6 feet. The entrance is to
be feet in width. The blocks of stone
will be cemented with cement from
Solano. Napa and San Bernardino'
counties and a special exhibit of ce-
ment viii be made from these counties.
One Of the most prominent exhibits
will be that of boraX and soda and
their by-products, that of boraX occu-
ping q space of 20x2O feet A large
globe containing water from Owens
Lake viii be shown, and beside it will
be the residue from the evaporation of
this water and the by-products OBJ
tanned from the residue. with illustra-
ton Of the uses TO which these by
products may be applied.
California is prolific in mineral waters
and they will be exhibited from twenty

Of recent discovery will form a prom
inent part of the exhibit. Among the
latter leDidolite or lithia mica from San
Diego County will furnish perhaps one
Of the most striking and beautiful ex
hibits at the exposition. A grotto Will
be formed, upon which will rest col

tered pieces containing crystals of pink,
blue and black tourmalines. AS no 9TH
er State contains such a variety and
quantity Of this substance the exhibit
promises to be Of exceptional interest.
VARIETY OF MINERALS.
The gem industry, which is now as
Stunning soIae proportions, will be well
represented - chrysoprase from Tu-
lare County, tourmaline and kunzite
from San Diego County and Turquoise
from San Bernardino County. Besides
these a number Of gems of minor i'm
portance and jewelers. materials in
great variety will be exhibited.
Another prominent exhibit which no
other State can produce will be inter
from large deposits which have been
found N San Bernardino and Inyo
counties. Probably no other discovery
in recent years is Of as much import
ance TO the state as these deposits,
which in extent rival those of Chile and
which need only the touch Of capital to
transform the inter industry into one
Of the most important.
a fine collection of salt has been made
both from the desert deposits and the
various evaporation plants in the State.
Massive exhibits of limestone, infuso-
rial earth, sulphur. asphalt and btu
minous rock, magnesite, gypsum,
graphite, chrome. potter's clay, coal,
fuller's earth, mica and other indus
trial materials Will be made. Massive
exhibits have also been collected of
gold quartz. cinnabar, copper, manga
nese and iron, which are illustrative of
the average character Of these ores.
Thousands OF small samples of ores of
all classes have also been collected and
will be exhibited in cabinets.
One of the most important features
which has been arranged is the infor-
nation bureau. Here II will be posi-
bic TO obtain information concerning
any mineral deposit in the State. One
wall Of the exhibit will be devoted to
the maps of all the mining districts.
and literature describing the same has
been prepared and will be freely dis
tributed.

Much attention has been paid to the
labelling of each specimen, no matter
what nature, with condensed informa-
