FROM LEVEL AND STOPE
Predictions Given Out in Regard
to the Trail Creek Country.
SUGGESTION ABOUTLEVELS
Mention in a Brief Paragraph OF Many
Matters That Are of Account in
the Everyday Work OF
the Miner.

1t is already clear says the British
Columbia Mining Record that the Trail
Creek district will this year make
large advance of output upon that of
1898, which in its turn showed big
increase on 1897, the shipments being
6S,S04 tons in 1897, and 111,2S2 tons last
year. Already up tn July 90 the Trail
Creek shipments of the year amount
to over 100000 tons and at the rate Of
progress now being made the Trail
Creek output for the year should easily
exceed 100000 tons The Center Star is
now beginning to be considerable
Rossland shipper, and should hence
forth bulk largely in the shipments of
Trail, the output of the NINE ror the
third week of July being 632 tons, or
rather more than half The output of the
lie Roi. The Center star is of course
one of the coming mines of Trail.
For convenience in handling timbers
in a large mine, wines should be cut
in or near the foot wall of vein,
reaching from level to level. Timbers
to be used in the stopc are lowered or
run down through the winze and de-
livered on the floor where they are to
be used. saving much time in under
ground hosting; and the WINES also
improve ventilation.
The oxidation of the upper portion
of gold bearing veins and deposits un-
doubtedly often results in enrichinS
that portion of the vein. The slow dis
migration Of porous gangue, or one
made porous by the oxidation of sui
phides, offers an unequaled facility for
the gold thus freed to settle deeper into
the porous portions of the rock, but
this process Is largely mechanical and
will probably account for compare
lively few instances where the upper
portions of gold bearing deposits are
found enriched. 1t is not unlikely that
the process of oxidation or iron sui
phides, nearly always present in gold
bearing ores, forms iron sulphate,
which, being a solvent of gold, dis
solves the fine particles of gold releas-
ed from the matrix, and this gold bear
ing solution, passing downward by
gravity into the porous rock mass, un-
der favorable conditions redeposits it's
gold, thus enriching the deposit in its
upper part and possibly depositing,
under some conditions, considerable
quantities Of gold at one place, form
ing pockets.
The sale of the Vina G. group Of cop
per and gold bearing claims at Con-
tact, New. for $4,000 has just been &C
compished by Miss r. T. McMasters.
the purchaser being Richard j. Bodies
of Colorado Springs. He was one of
the original owners of the Mollie Glib
son mine of Colorado, from which near
ly $1,000 900 in dividends was derived in
about three years, and has been, one
of the most successful miners in that
state.
The official figures for the Joplin dis
triCt show an output of lead and zinc
valued in 1898 at S700O,ooO. For the
first Il weeks of 1898 the output
amounted to $227l,552, and for the first
IS weeks to May 6, it amounted to
$S,SS0, 264. This proportion, if main
tanned would bring the value of the
1899 output to $l2,0O0000.
Mr.. ]. Morgan and James Rogers of
Deadwood are taking out rich copper
ore from their mine almost within the
| city limits of Deadwood on the south
side. Two shafts have been put down
! one of them As feet. The ore runs as
high as 60 per cent copper, and the
lowest grade is good enough to ship to
the smelter. The mine is located di-
rectly on the copper belt
