21719-Center and East Wa"ls with Elliptical Culverts in Foreground for Filling and
Emptying Locks; Miraflores Locks, Panama Canal.


In this picture we get a good view of a
side wall and a cross section of the middle
wall, where is shown one of the larger cul-
verts used in carrying the water to fill and
empty the locks. We can realize the amount
of water one of these culverts can hold when
we remember that the larger ones are of
about the same dimensions as the Pennsyl-
vania Railroad tunnels through which the
trains run from Manhattan Island to Jersey
City.
In the filling of a lock the large valves in


the larger culverts, near the miter gates, are
opened, while the valves at the lower gates
are closed. From the upper pool the water
runs through the large culverts into the
smaller lateral ones, ard thence it pours into
the lock chamber through the holes in the
floor. The lock chamber is emptied by open-
ing the valves at the lower end after those
at the upper end have been closed. By this
system of culverts the water is distributed
evenly and without danger of any disturb-
ance to the chamber which is being emptied
or filled.
