11479. Geography.-Culebra Cut extends from
Bas Obispo, some thirty miles south of the Atlantic
entrance to the canal, to Pedro Miguel, some eight
miles north of the Pacific entrance. WVe are looking
north over the deepest part, between Empire and
Economic History.-This is where De Lesseps, flushed
with the success of the Suez Canal, met his WVaterloo.
When the Cucaracha Slide began tumbling down about
the ears of his engineers they hopelessly fled. In all,
France dug away here from 1879-1889, took out 80,-
000,000 cubic yards of dirt and spent $260,000,000-all
demonstrating the utter impossibility of a 'ea-level
canal through Panama. After De Lesseps the New
Panama Canal Company worked from 1894-1904. Then
the United States bought France out and set to work.

tom, 500 feet below the original surface level at this
point, we see one of the famous Panama steam shovels.
It seems almost human as it puffs away at its hercu-
lean task. 'Ihis shovel has a dipper that can scoop
up seven or eight tons of cirt and rock at one mouth-
ful, hoist it, swing around, and deposit the load in the
dirt cars, one of which it can load in two minutes. It
weighs 105 tons. The record for a d.v's work for
such a shovel was 4,823cutic yards (8,305 tons).
