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:

21723-South End of Pedro Miguel Locks, Panama Canal.

The wall here shown is the center wall
of the Pedro Miguel Locks. We are facing
the south, looking towards the Miraflores
Locks, a mile and a half in the distance.
The valley intervening between this point
and the Miraflores Locks will soon be cov-
ered with water, and thus become the Mira-
flores Lake. The hills seen in the view
form natural sides to this lake atrd a dam
With locks and spillway will constitute the
barrier at the opposite end.
The width of this valley is not great,
hardly half a mile at most places and, in
fact, the area of Miraflores Lake is about
2 square miles, whereas that of Gatun Lake

is some 164 square miles. The water neces-
sary to form this lake will come from three
small rivers, the Cocoli, the Pedro Miguel,
and the Rio Grande. The course of the dam
is changed somewhat so as to catch the
waters of the Coccli river which flows down
just about where the locks are being con-
structed. Thus by making the dam run
mor 0Q, l ss parallel with the locks at Mira7
flores the Cocoli is made to empty into the
Lake instead of into the channel below the
Miraflores Locks.
The center wall here shown is the oppo-
site end of the one shown in view 21763.
