Mining Notes,

During the month of June S2SO,OO(
was paid in dividends by the mines of
Utah.
During the month ending June Both
there was shipped from Black Hawk
depot of the Colorado road $50 cars or
I.l1O tons of ore. representing the shin.
mpntS of smelling ore and t;iilingS.
The American Smelling and Refin,
ing Company has decided to erect an,
other stack at the Germania plant at
Salt Lake City. Ore supplies are in.
creaSing so rapidly that this is an alb
SOlute necessity.
The largest producer in Lcadville at
present is the Morning Star. operated
by leaScrS who are shipping about l.U
tons of oxi,ized ore daily to the Phil
hdelpha smelter at Pueblo The Ran.

Slmed shipments and are Sending out
about fifty tons per day.

The largest production of manganese
ore reported since 1891 occurred in the
calendar year 1898. according to statis-
tics just completed by the United
States Geological Survey. The war
with Spain caused diminution Of i'm
pOrtatiOns and the home production
amounted to 1887 long tons, valued at
S129. 1S1. an increase of almost II per
cent. over 1897.
1t is unadvisable to attempt to work
ore bodies or veins of greater width
than II feet without employing sills
on the floors of levels. owing to the
difficulties encountered when it be-
comes necessary to stOpe out to the
floor above. In smaller veins this NAV
DE accomplished by spragging the
posts and in other ways. but in large
veins these methods cannot be sue
cessfully used.
The Independence mine at CriDple
Creek seems to grow larger with every
month of production. The work Of
June shows a very substantial gain In
the ore reserves. The production for
the last month WAS BIO tons. OF the
gross value of S223.OOO. an average %:
more than S71 Der ION. The net profit
on this production was Sl5J.NW which
is just about what the company desires
to make each month.
No placer mine location can be made
by single individual which shall ex-
ceed twenty acres in area, and no
claim shall be taken by any association
Of persons greater than 100 acres, and
such associations shall not consist of
less than eight individuals. who must

regulations Of mining districts can re-
strict the size of placer locations to
less than twenty acres. although the To-
Gator is not compelled to take that
much.
1t is suggested that when shafts are
sunk through ground which is not sol
i'll enough to afford good support to
the timberS by wedging. reachers
should be put in every thirty to fifty
feet These are let into the walls, they
each resting on hitches cut deep
enough to hold. ana the timber firmly
wedged. The plates of the shafts rest
on these reachers at intervals. and they
support the weight Of the several sets
above as far as the next reacher. or
at least such weight as there NAV be.
This keeps the shaft sets firmly in
place. and there is little danger Of a
collapse -llcrald-DcmOcrat
