A view of massive amounts of machinery at work within the walls of the Miraflores 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.

21716-East Center and West Walls of Upper Lock Under Construction, Conveying Concrete
by Chutes; Miraflores Locks, Panama Canal.

A prodigious amount of concrete is being
used in the construction of the Panama
Canal. The side and middle walls of the
six double locks will require a great supply,
as well as the spillways at Gatun and Mira-
flores. Moreover the East dam at Miraflores
will require in its construction some 75,000
cubic yards of concrete. Altho the long dam
at Gatun is made of other mat rial its con-
crete spillway will contain about 225,000
cubic yards itself.
In the center of the view may be seen
one of the large culverts, 19 feet in diiune-ter.
These culverts run the entire length cf thi-

middle and both side walls. In the middle
wall of each of the six locks will be left a
space, through the center, whose shape will
resemble somewhat the letter "U." This
space will have a width of 44 feet at the top
and 19 feet at the bottom. It will be a
tunnel, whose bottom will be 15 feet above
the top of the large culvert, or about 42
cbove the surface of the flocr. The tunnel
vill be divided into three stories; the upper
ne will be a passageway for the operators,
ime second one for the electric current wires
uI.ed in oere1i o gates and valves, and the
lower one foi dr ainage.
