21709-View from Top of Construction Trestle, Showing 58-Foot Gate,
Pedro Miguel Locks, Panama Canal.


There is but one double lock at Pedro
Miguel. At each end of these Pedro Miguel
locks are mitering gates. These gates fit
together with their surfaces having a bevel
slope of 45 degrees. Altho the lift necessary
at the Pedro Miguel is a little over 30 feet,
the gate, as shown, is 58 feet high. The ex-
tra depth will be necessary to take care i
the pressure of the water and the displace-
ment of the vessels. Moreover the water
will be over 41 feet deep above the miter
gills.
It will take about fifteen minutes to empty
or fill a lock; quicker time would be apt to
cause troublesome currents in the locks or


approaches. Thirty minutes will be required
to pass a boat through a lock, and ten or
eleven hours will be necessary for passage
through the entire canal.
This picture shows also the concrete walls
in course of construction. In the distance
are to be seen hills showing the rolling na-
tui'e of thie isthmus at this point. For some
8 miles toward the Atlantic coast from Pe-
dro Miguel the country is quite hilly, and
here the canal has been dug through the
famous Culebra Cut. Throughout these 8
miles the channel has been narrowed down
to a width of 300 feet, whereas, in other
places, it runs from 500 to 1000 feet wide.
