made OF the Hazel Green ranges hy
Messrs. Burnett and Shelter, at the
expense of the late Jefferson Craw-
ford. There are ia this district
twenty-five well worked sets of
crevices running east and west, and
these are crossed by great number
of north and south crevices.
We have stated that up to 1913,
there had been more than forty.tLree
millions of lead ore raised from these
mines. Since that time, it is estima-
ted that eighty four millions (84 000,-
OOO) of pounds have been raised,
making in all, one hundred and
twenty seven millions. The Smell
ters' books show, that since 1915,
63, 900, 900 pounds have been deliver
cd. AT present, they are supposed
to be producing about 1000 600
pounds per year, mostly in working
over old grounds, without sinking
much or working new discoveries.
These diggings are high up in
geological position. According TO
Mr.. Scheller's survey, the elevation
of the village Of Hazel Green is 2S3
feet above Galena river, at the juno
ton OF the Hazel Green or Scrabble
Branch, or more than that distance
above this vicinity. And it will also
be borne in mind, that there are
several hundred feet Of mineral bear.
ing rock below US here. These one
hundred and twenty seven million
pounds, it will thus be- seen, were
produced ab0Uc the level of our river,
geologically. A. the present time,
as for some time past, level has
been in progress, which it is calcu-
lated, will drain these mines about
one hundred feet, we are told, o..
within one hundred and forty-three
feet of The level of the Galena river,
opposite Hazel Green. Even when
this level is completed, there will be
nearly one hundred aud fifty feet OF
mineral bearing rock lying above us
hero at Galena, geOlogically, that
will not have been reached, besides
ell that lies below US. Ono of the
grandest enterprises that we now
think of would be, the running of an
additional level from the level Galena
river 10 drain the whole extent of
these diggings to the depth of almost
$50 feet. Ii would open profitable
mining employment, al we believe,
for thousands of men, for hundreds
OF years, to develop the wealth of
this vast deposit.
The diggings occupy space about
four miles long from northwest to
southwest. the principal ranges being
concentrated IN the NJ rth west corner
of sections 30, 10, and %.
The diggiugs at Hazel Green have
never been extended to any consd-
cradle depth, and have hardly gone
below what is known as the upper
division OF the Galena limestone, and
probably do not reach within $50 feet
of the bottom of the rock. Whether
the sheets make into regular open
ings of greater depths than have yet
been proven remains to be demons
strated. The average depth of work
ing IS about forty feet.
The level that is now being run,
has 90 far progressed as to effect the
water on some of the ranges, and
that what is known as the Madison
range in particular. Shafts sunk be.
low the old works. we are told, dis
close now openings, with mineral,
some distance below the former was
ter level.
The most of the ore found in the
Hazel Green diggings is found in
sheets. Not only the norths and
souths occur in sheets, as in many
other diggings, but also the cas- 3
and vests tend to that form. Whelh-
or this form is continued at greater
depths or whether they open in large
crevices or caverns, like the Dubuque
mines, at greater depths, is only
matter of conjecture
Some attempts have been made to
take the water from these mines by
machinery, but the result was not
satisfactory Water is the miners
constant enemy-ever vigilanL. rs
persistant pressure will exhaust
physical force and wear out all the
contrivances of man in machinery.
At the Mills lode, in 1857, mass
OF ore was exhibited, more than
twenty feet across, and ranging from
two to three feet and half in thick
ness. Previous to that time there
had been taken from that mine 200 |
600 pounds of ore, and since that
time several millions more 1t was
taken out about forty feet from the |
surface and above water. The !
work was attended with great profit.
Single shafts, however, Shave been
sunk considerably lower, and the
work was attended with profit
