or at right angles 70 them and that they
are usually very much impverished,and OFT
en- barren, where they are not thus led, as
the miners call it, with those FEEDERS cross
ing them.
If this be true, and I think no miner
will doubt it, then our productive vClns
are where these two groups OF assures
meet: and our barren places where they
do not meet. 1t is this, think, that
divides our mining region into Districts or
mining eenters. Tf we take map 81
of any country where the mineral regions
are described, and the productive places
worked, we shall see the force Of tins
But in no mining region, are there features,
more distinct than in the lead district OF
Wisconsin.
Most of the towns and Villages in the
lead district are located at these mineral
eenters or groups of mineral ranges, r
rs [ have call, hem for convenience sake,
districts, and any one acquainted with the
towns and villages, by looking over an
ordinary State map will get the ideas.
If for instance. We so to the south west
corner of the State, and drive down stake
about Fairplay and then go four or tive
miles north to jamestown, and drive down
another and then draw two lines from
these stakes, east, or little TO the north
of east. to range seven in Green county,
we shall include within these lines, all the
mines of Fairplay, jamestown, Hazel
Green, Benton New Diggins, and Skulls
burg, no very important deposit of ore Is
found until we reach the east side of the
west Pecatonica, where at Wiota, there Is
another well defined group of mineral
ranges and still further east, at Monroe,
in Green County, we find another. But
east of Monroe nothing of importance is
found in the shape of ore.
While working out during last summer
the detaeS of this system of grouping
along this range of country, through nine
| ranges of township, | was never more
surprised in the results of a survey than
| 10 find, when figuring mp my notes and
| bearings that witt in widt of abou Z
| miles, we have belt Of mineral land x
| tending nearly an east and west direction
| for at least fifteen miles and dotted along
| the whole line, as mineral belts usually
are, with productive centers forming
mining districts. AS / stood, onee beaut :
lul day, on the high ground above the
village Of New Dieglns, with my compass
set to within few degrees Of east and
west, and looked over this long range OF
mineral district, so distinctly formed, |
| felt confident that in all my experience IN
mining and mineral lands, had not seet
OF such an extent, better defined belt OF
mineral land. Nor do [ believe that anotE'
err belt of equal extent and depth, either
in this or any other country, has yielded
more ore than this, or paid better for the
labor and capital invested.
! it is, however, one of the unfortunate
mistakes of our Statethat no mining record
has been kept, no clue, even, left us
to the quantity of lead ore thus obtained
We may form some idea, however of the
amount by putting together some scattered
facts recorded concerning portions of these
districts Hazel Green, perhaps, furnishes
| the most reliable; and our thanks are due
| to the late Mr.. Crawford fer these. Prof
| Whitney, who by the way was very care
| full not to over estimate oCr mineral re
sources, reported as reliable, $4,000, 0O'
lbs. up to 1860, with an annual yield Of
about two million lbs. This would give
Hazel Green, alone l49, 100000 lbs of orc
from group of mineral ranges, or mining
districts, limited to an area of not muct
over four square miles and another re
markable fact is, by far the larger portion
Of this ore has been taken from assures anc
openings above the water, at an average
depth of not over As or so feet And this
is only one of seven or eight such like pro
ductye centers, or mining districts along
this belt and nothing is more evident to {
| close observer than that tn Sc productiy'
centers are resting upon an underlying
cause that chains them together into one
belt of mineral land, with well dcfnee
bearing. j. MuRRlSn.
