less steel belt 1900 feet long. This
belt was made up of four foot panlike
sections, which Travelled in metal
trough that lay across the bottom Of
the cut. A hosting engine dragged
the great double end pillow back and
forth, and the plowed up material fell
into the steel pans, which carried it
across and up the steel incline, dump.
ing it on the "spoil" bank.
Another unique device literally
made hash of the stiff clay chunks
and hard earth so that the material
could be handled to better advantage.
A steam shovel dumped the clay and
earth into the hopper of the "granu-
lator," in which pair OF cylinders set
with great steel knives which inter-
meshed revolved and broke up the
clay. The granulator material fell
on to a wide belt, which carried. it up
to another belt, which travelled over
a bridge to the bank on the side of the
cut, dumping it there.
The cable ways which proved so ef-
fective in carrying off the blasted rock
were really suspension bridges 700
feet long. The main cable stretching
between the two tall towers-one on
each side the canal - was strong
enough to support weight OF fifteen
tons, and rocks weighing more than
eight tons were speedily and safely
lifted out of the bottom of the rock
cut and carried to the rock pile, sew
eral hundred feet away. The blasted
rock was loaded into great steel skips.
which were lifted up and pulled out
by system OF cables and sheaves and
automatically dumped.

lever bridges nearly 400 feet long.
The bridge was on a slant, the lower
end in the rock cut. Cars hauled by
cables ran up and down the incline
conveying the broken rock and Dump

The pneumatic dumps, which we're
a distinct novelty less than nine years
ago, promise to play an important
part in the excavation of the 18th.
mian canal. They were dump cars
which dumped over the side. The
cars, when filled, were made into a
train and q small but powerful loco
motive pushed them over the cork
screw narrow gauge track to the top of
the "spoil" bank. Each car was pro-
vided with q compressed air cylinder,
whose piston was connected with the
body of the car. All the cylinders
were connected with compressed air
pump and reservoir on the locomotive.
When the loaded train reached its
destination the engineer turned
valve and all the dump cars tipped
over sideways, dumping their contents.
Another >turn OF the valve and the
cars righted themselves and were
empty and ready for the return trip.
The channeling machine, which will
take hand in any rock work on the
isthmian canal, is . modification Of
the steam drill. It consists OF a verti.
cal boiler and engine, mounted on
four wheels, which run on q short
piece OF track. The engine operates q
great steel chisel and at the same
time actuates the mechanism which
moves the whole affair back and forth
on the track. While the machine is
travelling it's beat the big chisel chugs
up and down, cutting deep, smooth
cash in the rock on q line with sthe
edge OF the channel. While it is at
work line OF steam or air drills drill
holes in the rock across the channel.
Dynamite cartridges are put into the
hole and exploded and the whole mass
of rock is broken up, but the cash cut
by the channeling machine prevents
the blast from breaking the rock in
the side OF the canal, so that the sides
cut are perfectly smooth. Americans
have not built any Of the great ship
canals. The French built the Suez,
the Germans the Kaiser Wilhelm,
the English the Manchester, the
Canadians the Welland. In the
Panama Canal two opportunities are
offered American engineers and con.
tractors: Ono to complete the work
begun by the French, and another to
prove the superiority OF American
methods and means of excavation. 1,
goes without saying that our canal
builders will eagerly embrace both
opportunities.
