dition, so that a similar rock might be
expected at thousand feet or three
times that depth for that matter. Where
vein is found in normal state far below
the surface it simply represents local
condition, and may find counterpart
thousands of feet lower down, if it were
possible to reach it. After passing be-
low the influence of the surface (usually
depth of sixty TO 100 feet, rarely more)
the depth does not cut any marked fig
ure. There is no rule or law which in
huepces the richness of vein with in
creasing depth, though there is popu-
lar fallacy among miners that richness
increases with depth, the revrese is too
frequently the case. They forget, or do
not realize, that what are now the crop
pings on some mines, may at one time
have been thousands of feet from the
surface, the mountains having been de-
graded by atmospheric agencies. There
Is abundant evidence that the mines of
Leadville, Colo, were found at depth
of10,000 feet from the surface, but the
securing OF an immense glacier and
other erosive forces, have cut away the
mountains until now the ores in places
are exposed on the hillsides.
Every mine which ever made a pay
ing record in Julian should be pros
pected for lower ore shoots. Not every
claim may be expected to pay, but there
is little doubt that many will. With an
economical, intelligent management, not
parsimonious, but careful, much wealth
may come from the Julian district. The
sulphides have heretofore been neglected
almost wholly. There are few gold
mines where the sulphides do not con-
stitute a considerable portion of the
value of the ore, less, of course, than the
free milling gold, ordinarily, but still
sufficient to make their saving an OBJ
ject. The recent assay made on the sui
phides from the Helvetia returned $500
and over per ton. 1t is fact that there
are mines in Julian the value of whose
ores are entirely unknown.
ARIZONA ONYX BEDS.
Aaron Mason returned yesterday from
the Big Bug and Cave Greek onyx
mines, says the Phoenix Gazette. He and
his associates have bought an interest in
the Big Bug property, and have begun
shipping the onyx to San Francisco
to be worked up into holiday goods.
They nave also leased the Cave creek
ONYX bed from Holmes and his partner,
with privilege of buying. Men and
supplies were sent out yesterday to be-
gin taking out onyx for shipment. They
have already introduced it in San Fran
cisco, and have made arrangements
to work it up. This material is a
finer grade than the Big Bug article
and Mr.. Mason says it surpasses the
Mexican onyx, from the fact that it lays
in solid formation like marble, while the
Mexican product comes in boulders in
cement and cannot be secured in large
pieces. There is splendid place two
miles below the mine for water power,
which will be utilized as soon as the
property is sufficiently developed to JUS
| tify. Channeling machines will be put
in and operated by power transmitted
| from the water power by electricity. A
wagon road will be built and some of
the material shipped out within the
next thirty days. Mr.. Mason will leave
for California tomorrow to make further
arrangements to work these valuable
properties.
THE CAJALCo MINE.
w. W. Stewart returned yesterday,
states the San Diego Union, from the
mines, where he says everything is look
ing very promising. Though Mr.. Stew
art did not have time to inspect the
Caialco mine at the time of his visit,
he says he was informed that the new
level (2O0-foot) is opening up surpris-
| ingly we'll. The drift is being extended
northeastward along the vein, toward
what is known as the Williams shaft,
where it will be about 800 feet from the
surface. The vein on this, the lowest
level in the mine, is reported to have
widened considerably and some splendid
ore is being mined. But little beside
mining is now being done. Captain
Harris seems anxious to prove the ex-
tent and value of the mine.
NOTES.
The carload of ore shipped from the
Rose mine to San Francisco for reduc-
ton, says the Riverside Press, turned
out very we'll indeed. The lowest re-
turn is $197 per ton, and the highest
1924. They expect to have stamp mill
in operation before long.
A San Diego man who spends consid'
erable time in prospecting, returned
day or two since from trip in the
mountains east of the city and he thinks
he has found vein of tin stone in the
foothills of Laguna mountains. A quail
ity of tin ore has been sent to metal
lurgist for analysis.
The mint returns on the milled ore
sent to San Francisco from the AlvorC
mine show gold value of $1404 for the
SO ounces in the shipment, says the
Pasadena Star. This is an excellent re
suit, considering that quantity O
broken copper rivets became anal
gamated with the ore, thus reducing it
fineness.
Deputy Constable Harry Place hal
returned from an official trip through
the Banner mining district, says the Sal
Diego Union, and reports business
booming in that locality. A number 0
new claims have been located and ricl
leads discovered in mines now beini
worked. The Banner people are conf
dent that their district is as prolific IL
the precious minerals as any locality II
Southern California, and are determines
to demonstrate the fact in practica
! manner.
