Notes

Abstract:
A photo of an 1100 ton gate within the Pedro Miguel lock system, and the machinery and laborers working on its construction.
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.

2171 7-A 1100-Ton Gate Under Construction, Pedro Miguel Locks, Panama Canal.


To withstand the enormous pressure of
the water in the locks powerful gates are be-
ing constructed. The one shown in the pic-
ture weighs 1100 tons, and the total weight
required for all the gates on the canal will be
57,000 tons. As is readily noticed from this
view, these gates are made of steel. The
gates will be 7 feet in thickness, 65 feet in
length, and their height will vary from 47 to
82 feet. In order to lock through smaller
vessels with a saving of time and water, in-
termediate gates will be constructed in the

locks. These will divide the lo-cks into com-
partments with a length of 400 and 600 feet,
respectively. Less than five percent of the
vessels navigating the high seas are 600 feet
or over in length.
The lower gates at the Pedro Miguel locks
ill open into Miraflores Lake, a small lake
wiLt an area of about two square miles. ThiA
lake will be formed by the backing up of the
water from the neighboring streams by the
concrete dam with spillway on the east side
at Miraflores.
