Two hydraulic dredges at work near Gatun in the Panama Canal Zone.
Scope and Content:
B. L. Singley founded The Keystone View Company in 1892 in Meadville, Pennsylvania. The company quickly became the world's largest view company, having at least 250,000 negatives (of which some 50,000 were available as numbered views) by the 1930s. These images were meant to bring international experiences into the palm of the average person's hand, to be revisted in private or during social gatherings. It has been said that the ability of the stereograph to bring vicarious experiences to faraway people makes this medium parallel to the internet or television today. The Keystone View Company also focused on the educational value of their products, employing teams of people to write explanatory texts that were printed on the backs of the stereograph cards. This text, along with the imagery, presents the dominant vision of American ideals and interests during the late nineteenth and early twentieth centuries.

We have here a near view of the hydraulic
dredge seen at work just beyond the Gatun
locks in view 21725. These dredges are
used in digging out the approach channel to
the Gatun Dam. This channel extends from
a point opposite the city of Colon to the
locks, a distance of seven miles, altho the
distance from Limon Bay proper to the dam
is about three miles. The bottom width of
the approach channel is 500 feet.
The hydraulic dredges are used wherever
floatable, and thus become very economical,
for one dredge can accomplish as much as
eight steam-shovels (described in views
20853, 20864).

The hydraulic dredge has a distinct ad-
vantage over the steam shovel in that the
substance excavated is gotten rid of more
speedily. The material dredged out is mixed
with w:ter and thus, in partial solution, is
pumped thru a pipe line to the destined place
for deposit. In the middle foreground may
be seen the carrying pipe, which is rather
large in diameter. The pipe is supported on
pontoon bridges. That the hydraulic
dredge is a capable piece of machinery
may be gathered by closely observing the
two here shown with their double smoke-
