WHlkhlnk lou toua, ana THIS astonishing
weight was not the maximum the pow
erful rolling mill can do. for steel
ingots Weighing 100 tons can be rolled
into armor plates.
The electric crane. fumacoa and an.
planes necessary to handle such pro-
digious weights are all Of ample power
to deal easily and comfortably with
them.
Two hydraulic presses, each exertinr
a pressure of 1000 tons. bend to the
required curve tho heaviest steel armor
plate while # is cold
To drive one pair Of these armor
plate rolls. engines exerting 300 horse
power are required
Another astonishing production in
steel was a boiler plate Of the enor-
nous dimensions OF SO feet long, II
feet wide and 11-2 inches thick and
weighing 20 tons.
In the forging OF heavy steel ingots,
hydraulic presses Of 5000 tons pressure
are used, and the writer saw a built mp
marine shaft for a North German ATT
lantic liner that was 226 tons In
weight and 233 feet IN length.
Another finished solid screen shaft
was made OF crucible steel, made from
an ingot 80 tons weight, and forged UNI
\ der a 5000 ton press IN GO hours TO
a length of 14S feet; afterward this re-
markable solid shaft was "trepanned."
bored for its entire length to make 1t
hollow, /. e., to have hole all the
way through
This long steel shaft was turned and
bored in a lathe which believe is with
out a compeer in the world, its dlmen-
sions being:
Length Of bed, 1G6 feet inches;
length between centres, 152 feet
inches, and all its component parts Of
suitable elephantine proportion.
In ordnance, it is well known this
firm has held for long time a reputa-
ton of the highest class, and the num-
erous guns to be seen from so ton
gun down to a 1 pound gun, were splen-
did specimens Of the highest quality Of
such articles.
saw one Of Kfupp's so ton coast de-
fence guns, 12-inch bore mounted all
complete in a revolving turret, and this
terrible weapon is capable Of penetrat-
ing the thickest and most modern type
of armor that is used for the protection
of ironclad ships at any distance at
which an ironclad would attempt to
destroy coast defence work.
The gun is of special crucible steel,
and is fred electrically; the barrel is
40 feet long. When charged with 291
pounds Of smokeless powder, behind a
shell weighing $50 pounds, it has a
muzzle velocity of 1890 feet, and can
send the shell twelve and one-half
miles. At a distance of 1893 yards it
can send a shell $50 pounds weight that
will penetrate a solid wrought iron
plate so ga inches thick, or an ordinary
steel plate 35 IL inches thick.
"Krupps" patent hardened steel plate
10 IL inches thick
The various kinds of portable field
guns for army purposes made by Krupp
have long been known as Of the very
first rank in every way.
The writer was favored by an invita-
ton to witness some actual firing tests
at the gun testing range, but space will
, not allow for more than one to be de-
scribed.
A field gun firing a IA IL pound pro-
, jectile with a charge Of smokeless pow

with a range Of three and three-quarteI
miles, fired easily twenty rounds min
ute aimed at a target.
At a short range ten shots were fired
