There never was so much prospecting

The museum of the State Mining Bu-
reau has more than doubled its aver
Ferry building in February. Ever since
then Curator burden and his experienced
assistants have been busy with the ar
rangement of the specimens IN the wall
and show cases and the work is now
practically completed. The collectlon
crowds all the available space in the long
and light hall it occupies on the third
floor and makes a very attractive and
unite imposing array. Two years ago
there were 10 900 specimens in the collec-
tiOn but now only about 10000 are aus
played The collection has been improved

Many others belonged to the late JACOB
r. Davis who was so long trustee and
who took a great interest in the inst1tu-
ton Besides his valuable mineral CON
tributions there were several hundred Gu
rios, such as ancient arms ana South I Sea
things which were simply loaned. The
heirs have removed these. There used to
be a collection of stuffed birds ana these,
too have gone to the park. There are
number of these curios left to interest the
casual visitor but the collection has been
made almost entirely mineral one. AS
such it has been improved by culllng out
dunlicates and specimens of small inter-
est or value. 1t now delights between
four and five hundred visitors a day;
many are people intelligent In mining
AS the display of the State Board of
Trade is on the same floor in the other
half of the building the two INSTITUTIONS
mutually increase their attendance. There
is also an increased attendance at the
library The collection is steadily grow
ing and is also being improved constant
~ by the substitution of better specl-
mems.
During 1898 the Selby Smelling Company
deposited over sci 600 ,0G0 in refined gold at
the San Francisco Mint, ain increase of
nearly 50 600 900 over the deposits of 1877
The largest proportion of this gold came
from California mines, as Selbys receive
probably three-fourths of the California
product at the same price paid at the
Mint and then refine it. Its books en-
able a segregation of the amount of
California gold and so help the Mint
statfstician in arriving at the figures of
tho total California production yearly
The rest of Selby's gold deposits come
from the Klondike. Alaska, British Co
lumbia, Mexico and farther south.
Many copper claims and partly devel-
oped copper mines are being bonded or
sold along the copper belts from PiumaS
south to Medera and Fresno counties, and
prospecting for copper is very active as
consequence of the copper boom ana ana
one of the latest to be sold is the Cross
mine in MADEIRA county. which has been 6ed
bought by New YORK men IoF Si5o'UJu
This mine has been worked in a small way
for years. The Campo Seco mines IN
Calaveras county are among those in
which active work is being resumed:

The resumption of work at the Darling
mine situated on Bear creek, near
Georgetown. is about the best piece of
mining news it is our pleasure to an
nounce this week. says the Mountain
