Deep Mining.

LINDEN, july 3ISt, 1899.
SINS i have been for time intending
to write you on the importance Of deep mining
in this section of the country. But feeling my
self incapable OF the task, have deferred to the
present However will endeayor TO write you
in my own language and use my own mining
phrases in expressing myself
My first object will be to show that deep mi
ming is warrantable, and indspensably neces-
sary secondly, that there is great analogy in
the stratlfied rock here and the rretallIferous
rocks IN Cornwall and Derbyshire, England /
The sand rock here as in other places, is COM
bination of PARTICLES of rock from all parts of
the earth consequently it has 4 tendency to
bring the crevices connected with the same lodes
IN their proper places, as you will perceive
marked out the sketch. N order to satisfy
you that deep mining is warrantable here,
would beg to send you few particulars respect
ing the great lead region in Derbyshre, eng
andy where there have been mines worked up
wards of 900 years these being entirely in
the magnetism lime rock. In traversing this
country throughout you wilt find the upper
magnetism lime rock. sand rock and lower map-
neslan rock precisely the same as we have it
here. And if specimens of this rock were
placed into the hands of the most scientific
miner that could be found, he could not tell
whether 1t We're found ia Derbyshire or Wiscon-
sin
The upper magnetism lime rock is to be found
only in the upper parts of the high bluffs Con-
sequently the sand rock in most places becomes
the surface rock. After the old men had work
cd out some OF the heaviest deposits of lead ore
I in tho IL
ton to deep mining and commenced exploring
the deep ravnes at the out crop of the sand rock
where every practical miner would say that good
iodes could be depended upon. In drifting
few fathoms in the upper pat OF the lower mag
neslan lime rock at the bottom Of the out crop
of the sand rock they discovered the same lodes
as in the stratum above, which was entirely cut
off by the sand rock. without even the trace of
4 lode 70 be seen. From these important DIS
coveries mining again established from
which the nobility of that section of the country
made such rapid fortunes rs to be scarcely cred

weeks since. He says lie was well pleased to
see the lodes 50 rich and also to find Derby shire
lead bearing rock in Linden, Wisconsin.
/ The diagram which have sent you will show
all the crevices connected with the main lode
here, giving practical men confidence in deep
mining. You viii observe in the sketch. that
/ below the sand rock-the last crevice connected
with the range falling into the main lode In
traversing the whole lead region-with a care
| full examination, YOU Will fiud the out crop of
every floor of rock from surface down to the
lower magnetism lime rock the appearances of
which, | am pleased to say, are warrantable for
deep mining, even from Mineral Point to Lake
! Superior, with a proper selection of lodes an d
legitimate mining.
In following up the lodes to n deeper level
you will meet with different strata. good. bad
and indifferent, as in all other mining regions
with some such changes as you may not expect
to see. 1t IS my opinion that many of these
large lead lodes will in depth produce untold
quantities of copper ore, and more than proba-
bic IN the primitive rock may be found tin and
copper. Although tin has not vet been found,
n persuaded that if We were able to sink
through some of the different strata beIow-+bo,
not so deep as some of the mines 10 Cornwall
our " isconsIn mines would stand at the head of
the list as the best tin and copper mines in the
world and from the knowledge I have of mi
nlng here and elsewhere, would say nv motto
shall be deep mining. AS 4 proof of this-as the
poor widow said In the gospel would give
the last cent, provided that it could be well ap
PLied IN developing the mineral resources which
are now locked up in the great stone house of
nature II IS said by some here that mining is
not In Its anrdnt state, having been working over
80 years. Forty years ago in Cornwall heard
old men say that mining then was In its infan-
cy with them, having then been in operation
over enc thousand years.
If this be true, the mines in Wisconsin rnust
SUI be IN tier mothers womb and hope the
day Is not far distant when she will be deIiv-
efed and the infant becomes mighty man.
" hen hear of parties saying the mineral for
nation here bears analogy to the mineral
strata IN Cornwall, 1t carries my mind back to
my boyhood days when I worked at a mine
known by the name of Poiborrow. Cornwall /
ms was Tlch TN mine, and subject to the
same horizontal sheets of tin and pitches as we /
have here IN the upper formation The upper
formation there was so fathoms thick from sur-
lace down from which point the tin was en-
ureiy cut of, and not trace of it to be seem /
