| GRAVEL MINING IT GOLD RuN.-The Scientific
Press says; "The abundance of rain falling SO
early this Fall has had the double effect of part
ly filling the bitches and Of spurring the miners
to their best efforts, to complete their prepara-
ticns for the Winter campaign. Most of them
are now ready, and some of the claims belong
ing to the Gold Run Ditch and Mining com
pany have already started up, namely: Bay
State No, g. Gold Run Pine Top and
North Star These claims are and always have
been good paying. The Cedar creek company
are also running some of their claims one at
Gold Run, the Gem, and one or more at Dutch
Flat. The mining season may therefore be said
to almost have commenced in earnest in these
localities, though there many claims that
will start mp when the bitches get full as for
instance, the 'Goarling Ravine Company, the
Miami, belonging to Messrs. j. and r. Has
kins, and other claims.
The Gold Run Ditch and Mining Company
are also laying their pipes to the old Indiana
Hill! claims, which will be opened Immediately
upon the completion of their shaft anl tunnel
rns tunnel has beer driven very energetically
and is undoubtedly the quickest it is one of,
the best pieces of work of the kind in the State.
The main tunnel is 10x12 feet. and is intended
to be 200 feet long, when it will tap the old
40 "a shaft, which is sunk on the channel of the
Blue Lead to depth of about 200 feet in fin4
hydraulic gravel; 450 feet from the mouth of the
tunnel their branch for the Indiana Hill claims
starts in; this branch is SxS feet, and is now in
1000 feet. 1t will be run 200 feet longer when
their shaft or incline will be raised. They ex-
pect to be ready to wash in February. This
tunnel was commenced in July, 1873; aud that
it has been run that size ard distance through
very hard rock in about 16 months (actual work
ing time perhaps not more than IA months) is
certainly very creditable to the manager. The
work has all been done with the Burleigh drill
That this company will meet with the success
the magnitude of their work and outlay demands
is certainly the wish of every one, and is almost
assured, for they will open near the center of
the channel of the Blue Lead with bank of
hydraulic ground from 15Q to 200 feet deep, and
richer than anything worked in Gold Run be-
fore; besides the bedrock and strata of cement
lying upon it has been proven very rich.
The adjoining claim, the Indiana Hill Blue
Gravel Mining Company, or, as it is oftener
called, the Cement Mill Company, is exclusively
drifting claim or claims as the company has
several They work breast about feet high
and 100 feet wide, employing about 25 men.
They crush the gravel using an eight t-stamp
mill. and about Is inches of Water. The mill
crushes abont As carloads in "a hours, each
carload weighing about 1000 pounds. This
company has been to work upon the channel of
the lead for good many years, and as a sample
OF its character we give the result of their last
years work, obtained from reliable source
In 1874, with a nine months run, they crushed
10.017 carloads, which yielded $50, ,S1l so. an
average of SO and fraction; in 1873, with
seven months run, $500 carloads, yielding
$24, 900, average nearly 81; in 1872, with four
and half months run, $500 carloads, which
yielded S19,410. average $5 and fraction.
The cost of production and mining is about 81
per carload. This company is now working
full force Of hands and will make the first clean
up for the sehson in n few days.
