Abstract:
A single man stands in front of a vast number of wicket girders being used in the construction of an emergency dam in Gatun.
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.

21728-Looking Across the Wicket Girders of the Emergency Dam. Catun, Panama Canal.


.We see here the wicket girders of the
emergency dam described in the two preced-
ing views (numbers 21725, 21727). 'iie
dam of which this is a part is in reality a
framework which can be quickly lowered
into the locks, and upon which can be
quickly built across the locks an iron wall
consisting of metal plates fitted closely to-
gether. The question is how is this iron
wall to be built across the locks when per-
haps a gate has broken and the current is
rapidly flowing thru the lock?
When the bridge is swung across the lock
the water will be rushing parallel with the


girders, or from right to left of the picture.
Immediately these wicket girders, hinged
to the main bridge at points toward the left
but farther than can be seen in the picture,
will be let down until their ends touch the
floor of the lock, fitting into a pocket pre-
pared for them. The girders thus placed
now form runways for the metal plates
which are run down at right angles tof the
girders, making a dam ten feet high. When
these are in place another series of metallic
plates is let down. This continues until
the dam reaches the desired height.
