A main problem-in fact, the chief prob-
lem-in connection with the construction of
the Panama Canal has been that of landslides.
Nor has this problem ceased to be a most
annoying one since the opening of the Canal
for the accommodation of commerce. The
principal slides that caused great delay were
the Cucaracha slide in 1913, and those oc-
curring at Culebra (now Gaillard Cut), in
1910, and again in 1914 and 1915.
The one here shown is especially bother-
some and means that at least 10,000,000 cubic
yards of earth must be removed before the
Canal :ill again be in its normal condition.
However, navigation will not be held up
until all this material is removed, but will
Copyright, 1916, by The
be opened up just as soon as it is safe. Gen-
eral Goethals, the expert engineer in charge
of the whole Panama Canal Zone, states that
one million cubic yards can be removed per
month. The cost will be not more than 30
cents per cubic yard.
The bad feature of this recent slide is that
slides have occurred simultaneously from
both banks. All sorts of methods have been
employed to make the banks stable, like
planting the slopes with grasses and trees,
driving in piles, covering the surface with
cement, etc. These have been unsuccessful
so far, and even large trees that have stood
on the slopes for years have gone down to
the canal bed, maintaining their original
Keystone View Company.
