Several laborers and a single middle-class man standing around the emergency dam 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. Source 1: Source 2:

21726-Side View of Emergency Dam, Gatun, Panama Canal.

The builders of the Panama Canal have
been able to profit by the experience gained
by the builders and operators of the Suez
Canal. It has been found that certain pre-
cautions must be taken, notably to provide
for damming up the locks in case of accident
to the gates. This was plainly demon-
strated by an accident in the Suez Canal
when a ship got beyond control and rammed
the gates.
The emergency dam shown in this view
has been invented to provide for this need.
It is in reality a bridge of the cantilever

type, resting at present on the side wall of
the locks running parallel with the lock
wall. It rests on a pivot in the side wall of
the lock, near the operator's house to the
right. The end toward the left is free and
can be swung towards the right across the
lock on the far side of the m mine. The
mechanism needed in operation the emer-
gency dam can be better seenrn the next
view, number 21727. These movable dams
will be found at the head-bay of the upper
locks of each flight of loclk.
