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.

At Gatun there are three double locks giv-
ing an elevation of 85 feet. In this picture
we have a good view of the east chamber of
the lowermost lock, with a partial view of the
concrete middle wall. The northern or
lower end i:; shown with its coffer lam,
i which is a watcr-tight enclosure. Beyond
are th" excavating dredges. They are dig-
ging o at a channel, 500 feet wide, which ex-
tends over seven miles to deep water. The
depth is 41 feet or more throughout.

A lake is formed at Gatun by a large dam
which impounds the water from the Chagres
River an. its tributaries. This dam is nearly
1~2 rril"; long, but only 500 feet, or 1 .15 of
its length h, will be exposed to the maximum
85 foot water head. The width of the dam
will vary from almost a half mile at the base
to about 400 feet at the water surface, and
100 feet at its crest. The top of this dam
will be 30 feet above the level of the lake, or
115 feet above the level of the sea.
