DEEP MINnHo.
what are Regarded % Europe ~
0rsas Shafts.

Twenty years ago the deepest mining
shafts 10 the world reached only about
1000 feet below the surface. The very
deepest, We believe. was . metslifrrous
mine In Hanover. which bad b-en Car.
risd down to the depth OF 1900 feet. The
deepest perpendicular shaft today 10 the
Adslbsrt shaft 10 . silver lead mine In
Prizibram. In Bohemia. which. In May
last. bad reached the d,pth OF 1000 me
ters-32S0 feet. The attainment Of that
depth vas made the occasion OF three
days festival. and still further notice by
the striking OF OF Q large number Of
commemorative silver medals. OF the
value OF . form each. There 10 no
r~cord Of the beginning OF work on this
mine. although ito written history goes
back to 1877. Quite recently an elegant
commemorative volume has also been
written and printed. which an English
paper before N says 10 ''most Interesting
to those who have . taste for either the
actualities or the antiquities OF mining
industry"
There are two other localities. how.
ever. where . greater depth has been
reached than at the Adalbert shaft, but
not in . perpendicular line. THESE are:
hnst, the Rocksalt bore hole, near Spsr.
epbsrs. not far from Berlin, which O few
years ago had been bored to o depth Of
ATS feet; and. second. the coal mine at
vivisrs Leums. 10 Belgium, where the
miners. by shaft sinking. together with
boring. have reached . total depth Of
3542 feet. Taking each sipRly. the
deepest shafts In the world, at the pres.
ent moment. group themselves accord.
ing to the following order:
!. The already mentioned Adalbert
shaft, $3.50 feet deep. As the top Of
this shait 10 1732 feet above the SEQ
level. the bottom 10 OF IN l548 feet
below IL.
2. Two shafts near Gilly. In Belgium.
are sunk to the depth Of 2847 feet. At
this depth both were conn. ctsd by .
horizontal drift. from there an exploring
shaft was sunk to . further depth Of 866
feet. and from there again q trial hole.
40 feet in depth. 10 put down. 90 that
the total depth reached 10 3542. As
they did not. in the bore hole. discover
the sought.for coal seam. they have
returned to the shaft at tho 2847 level.
8. The Eimgksrts shaft Of the Lu9aur
Coal Mining Company. Rhenanis, Lu.
Rsu. in the kingdom Of Saxony. 10 1858
feet deep.
4. The Samson shaft OF the oberhartz
lead and silver mining works, near ST.
Andressbsrg. Hanover, has . depth Of
24S7 feet. and 10 ct present the deepest
shaft OF Prussian mining.
8. The winding shalt OF the Rose
bridge colliery. near WiRsu. Lancashire.
England. has . d.pth Of PASS feet. Coal
10 drawn from the hanging N at the
24l8 level. Tue time Of tho cage run
Mug this distance being nfiy Ave sec.
onds. the winding rope has, therefore.
an average speed Of iorty.iour feet per
second.
6. A shaft at the coalmines Of St.
Luke. near 81. Chsumont In the Loire
department, France. reaches 2263 feet.
Z. Tbs shalt Of the Dunkirk oolliery,
near DunkinAsld, Lancashire, 10 2069
feet deep. but the mining il prosecuted
to o further depth Of 756 feet BY shafts
from the lower levels. making . total
depth Of the mine Of 1884 feet.
8. The deepest shaft OF the collieries,
Ronchsnp. In France. 10 1881 ieet.
. similar depth has been reached BY the
arR-p,iferous mine. near Konigsbers. In
Norway. The mines belonging TO the
Roros copper works, In Norway. have
been worked to Q depth Of from 264o to
a270 feet.
o. The Amslis shaft. In the mine
works near Schmnitx, In Hungary, 10
1852 feet deep.
10. The No. I Camphaussn shaft.
Fishbsoh. In the department q The
colleriss, has now reached the
depth Of 1855 feet. and may possibly
the deepest shaft In Prussisn
coal mining.
Although the depths to which the
shaits enumerated have been penetrated

and practice OF mining may appear
