Mechanical Phase of Canal
Fred A . Calvin Telia of Elements That Enter Into the Great
Panama Waterway
Tfc« Panama canal has succeeded. That la now to be taken for
granted. Before to very long It will have brought together the two
gn at aides o f the world.
To the commerce o f the world the canal

o f the long voyage around the shoulder o f a continent The waters o f
the Pacific ocean lave the shores o f the lands wherein dwell one-half the
population o f the world. To these people there will come through the
canal the civilisation o f the modern times. Through the canal will sail
the twin goddesses o f health. Hygiene and Sanitation. Upon the dis
ease-ridden east the prophylactic touch o f Tankee methods o f right
living will descend as a benediction. It is our canal, too. It was made
poaslhle by American knowledge and American pluck and American in
genuity. Where the French and the English and the Spaniards, i f we
go beck far into the history o f the Panama country, failed, there have
we worked a miracle, a wonder o f science and intelligence, a toon to the
whole world. There is in the Panama canal much ground f i r national
pride. It is to be hoped that the administration o f the canal shall
find its measure in the remarkable standard o f its building.
The article that is to follow was written by Fred A, Colvin, as

this place, and here all the locomotives
and cars for the excavation work as
well as for the Panama railroad are
repaired. At times this shop has em
ployed 1,800 men. Tt is difficult to
see the necessity for such a large shop
until we stop to consider that the
Isthmian Canal Commission railroad,
built solely in the Culebra eut and for
hauling the d:rt (oc “ spoil,” as it is
called) away from it, is about the size
o f the Boston & Albany railroad.
There are over 300 locomotives and
4,000 cars, and most o f the locomo
tives are big ones, weighing over 100
tons each. They are very unlike the
usual

usually think o f in connection with ex
cavation work.
At Empire the steam shovels are
repaired and the shops employ about
700 men at times. It takes a lot o f
shop work to keep the dirt flying, but
they are kept at work with as little
delay as possible by a thoroughly or
ganized plan o f action and a corps o f
inspectors and workmen.
The inspectors visit each shovel as
it works away, and not only gets the
reports o f the shovel engineers, but
look it over for weak spots and worn
parte. Any needed repairs are re
ported to Empire by telephone so that
repair parts and supplies can be pre
pared in advance.
A fter the dirt trains have stopped
running at 5 p. m., the repair train
starts out from the Empire shops and
makes its rounds to the steam shovels
which are in need of its services. This
repair train consists of a heavy loco
