Abstract:
Several large ships passing through the Pedro Miguel Locks in the Panama Canal.
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.

SHIPS PASSING THROUGH THE
PANAMA CANAL
The Pedro Miguel Locks of the Panama
Canal are at the South or Pacific end of the
Canal. Strange to say the Pacific end of the
Canal is farther east than the Atlantic end.
Thus the sun rises in the Pacific and sets in
the Atlantic. A glance at the map will show
how the Canal Zone cuts across the Isthmus
in a diagonal line. The Pedro Miguel Locks
with their flanking dams, extending from the
side walls to the hills on either side, hold at
summit level the waters of Gatun Lake and
G: ard Cut. The waters of Gatun Lake are
.nally 85 feet above sea level. The Pedro
ael Locks raise or lower ships 31 feet, the
rence between the summit level of 85 feet
the normal surface of Miraflores Lake,
eet above sea level.

The Locks of the Canal System are in du-
plicate and are constructed in the same manner
with all lock walls on rock foundations. At
Gatun Lock there are three flights, at Pedro
Miguel one, and at Miraflores two. The aver-
age time required to pass a vessel through these
locks is one hour for Gatun, one-half hour
for Pedro Miguel and three-quarters of an
hour for Miraflores. At all times during the
process of lifting, a vessel is in full view of
the men who are controlling it and it is as safe
as if tied to a wharf.
On August 11, 1939, Congress authorized
the construction of an additional set of locks
paralleling those already in use. The new locks
will be 140 feet wide by 1,200 feet long and
will handle any ship afloat or that may be /
contemplated for. many, many years to come. :
