Notes

Abstract:
A view of the massive amount of steel and machinery working within the north end of the Gatun Locks.
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.

21718-Extreme North End of Lower Lock Showing Immense Steel Monolith Forms on Tracks,
Used in Construction Work, Gatun, Panama Canal.


An idea of the immensity of the lock walls
may be gained by carefully observing the
large monolith forms, with seven different
platforms, which are used in their construc-
tion. The walls at Gatun, as well as at the
Pedro Miguel and Miraflores locks, are of
concrete.
The spillway from the Gatun Dam to the
tide-water level will be an opening lined with
concrete also. In this spillway there will
be 225,000 cubic yards of concrete. To regu-
late the water-level in the lake the spillway
will be closed by a dam of concrete. The


dam will be regulated by gates. The width
of the spillway is 300 feet, and the length,
1200 feet. It is cut through a veritable hill
of rock, just near the center of the large
Gatun Dam.
The Gatun Dam forms a break-water to
the Gatun Lake, whose surface will be 80
feet above the bottom of the lowermost lock.
This dam is constructed from a natural com-
bination of clay and sand. These have been
dredged by hydraulic processes from neigh-
boring pits, and then placed between two
large masses of rock and other similar ma-
terial,
