Notes

Abstract:
One worker and various machines stand atop massive concrete walls that are facets of the Pedro Miguel 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.

21708- Massive Walls of Concrete, Pedro Miguel Locks, Panama Canal.


The Panama Canal is about 50 miles in
length from deep water on the Caribbean Sea
side to deep water in the Pacific Ocean.
However, it will be but 41 miles, or a little
more, from shore line to shore line. The
canal has an elevation of 85 feet from Gatun
on the Atlantic side to Miraflores on the op-
posite coast, a distance of some 34 miles.
To raise the ships to this 85 foot level, three
large double locks have been built at Gatun.
To offset these locks there are three more on


the Pacific side, two at Miraflores and one
at Pedro Miguel.
The Pedro M.iguel locks give an elevation
of 30 ft. 4 in. This pair of double locks
(like all the others) is 1000 feet in length and
110 feet wide, Each of the locks is a chamber
whose s'd-s a nd floor are constructed of con-
crete. At each end of the double locks are
rritering gates. Altho these concrete side-
walls are about 50 feet wide at the floor, they
taper up to a width of 8 feet on the top. The
face-side is perpendicular, and the tapering
begins 24 feet from the base.
