mining districts are regarded by
many persons, and some Of the rea-
sons therefor. We now propose to
show that there is in fact no ground
for this prejudice against limestone as
an ore-bearing rock, by giving list
in part Of mines occurring in lime
stone that have been productive, with
a brief reference in some cases to
their magnitude and value. In Eu-
rope, the silver mines of Schemnitz
and Kremnity occur In formation in
part limestone, as do also the copper
silver mines Of NeushoI- The mines
near Abncdbany occur in formation
IN part limestone. The copper, silver,
and other mines Of the Bannat of
Temeschwar occur in part between
the limestone aud syenite porphyry.
The important iron mines of vosges
occur IN part in limestone At Pierre
vile. in Brittany, the lead mines oc-
cur in limestone At Orijerwy there
is a copper mine whose gangue is car
Donate Of lime At Aurosar, nt ar Fe-
lin, the lead mines have been worked
in the transition limestone. The
Haugaron mine, in the valley of the
Asson, occurs subordinate to transi-
ton limestone, as do also the deposits
Of hydra.e of iron, worked for hun
dreds of years at Racine in the valley
of Viejessos. The copper-siIver mines
of kutz Publ, in the Tyrol, occurs In
limestone and clay slate, and had been
worked to depth of $500 feet as
early as 1859, a greater depth, we be-
lieve, than has yet been reached by
any mine on the Cumstock. Tie sill
ver-copper mines, generally. near
Brixlegg, in the Tyrol, occur in lime
stone At Schwartz, in the tyruI, the
siiver-copper mines occur in c0ntin-
uation of the same limestone belt found
at Brixlegg. Lead mines occur In
limestone ON tn. slopes OF the Alps in
Corinthia. The celebrated quicksil-
yer mines Of !dria, in Spain, occur in
formation mainly limestone. In the
Thuringian Forest, copper, silver cop
per, cobalt and iron mines occur in a
formation mainly limestone. In West
.phalia. zinc and lead mines occur in
limestone. The Smithsonite deposits
carbonate Of zinc, at Weisloch in Bad
en-, occur in limestone. The limestone
at Grave contains gold finely dissent
mated through the rock. The lime
stones Of upper Silesia contain zinc,
lead, and iron ore deposits. The las
limestons at Grave contain5 gold fine
y disseminated through the rock
The copper and lead deposits at
Clausen, in the Tyrol. occur in for
nation in part limestone. The silver
deposits near Allemont are in lime
stone. At Bluberg and Kreuth, III
Coriuthia, the deposits occur wholly
in limestone. allhou b numerous adits
Ior drifts and levels, as we would tern
them, have been driven into the slate
and slinkStone. The ore deposits are
pipe-shaped, like the Richmond and
the pipe veins of England and Ireland.
and are called ore-pipes or chimneys
In the kreulh sut-district eighteen Of
these pipes ar cllimneys of ore occur,
whose diameters vary from nine to
forty-6ye feet. These pipes have been
worked to a depth Cf six hundred feet
These and adjoining districts proba
bly, as nearly resemble the Eureka
District in the mode in which the ore
occurs as any others that have been
worked, except some of the ines oi
