eases have been arranged, consisting
Of FIVE on each. side. Between the cases
large stands. have been placed on which
are arranged in pyramid shape mas
sive. pieces Of. ore. The ores are ar

right Of the arch. Next to the cop.
Per exhibit. two cases % cinnabar ores,
with two stands containing massive
samples Of the ores. are placed. Thare
is also native mercury from SolanO
County.
The copper ores are representative
samples The most prominent mines
as Wei as many prospects are here rep.

from Shasta County, the smallest piece
weighing $50 pounds and the largest
over 1900 pounds. Bars of blister cop

Here We have a showcase containing
miscellaneous ores. Next to that IS a

stands contain pyramids of the mas
siye' samples Of ore. These ores are
from all the counties but Nevada, that
county having made a special exhibit.
The gold ores OF the State, like the
balance. of the exhibit, are as nearly
representative of the average ore as
IL was possible to obtain. These ores
were collected from .Siskiyou to San
Diego. This exhibit differs materially
from those of past expositions, in so
far as no attempt was made to dis
play gold specimens, with the excep-
ton Of some $4,000 worth of gold
quartz specimens purchased by the
commissioners. Owing to the fact that
the. commissioners refused to furnish
bonds for. the safe return of choice
gold specimens and the State. Min.
eralogist did not wish to assume a per-
sonal responsibility, only a small case
OF specimen gold quartz and nuggets
are shown by the State.
LEPIDOLITE COLUMN.
Leaving the gold ores, one is at
tracted TO what is the rarest and one
of the most beautiful exhibits in the
Mines building, at the same time one
of the most unique, viz, the lepidolite.
or lithia mica exhibit, the apex of
which can be seen from most parts OF
the building. When this is seen from
a distance the visitor at once deter
mines on a closer inspection. A large
exhibit of this nature excites wonder
To the casual visitor the CRYSTALS of

and the variety Of coloring in the for
nation, appeals to the artistic fancy.
Many demands for a specimen of the
lepidolite have been made by visitors
