RAISING SUNKEN VESSELS.
Insurance companies und others interested,
are often surprised to see vessels contniving
valuahle corgses go down unneeountohly in
the still wuters of a harbor, ond there lie tuuntingly in view, but defying nll attempts at raising them to the surface. Numerous plans
have been devised to meet such emergencies,
but generally without success, as in euch case
. a second litt, when the whole process is repeated as often ns may be wecessary to raiso
the vessel to the surface.
The priveipal novel fentnre of this invention
is the method of introducing the chnins under
the keel of the vessel hy means of power applied above the water, together with the lever

Sugeest a plon of operations. Inventors are
now, however, heginning to take the matter in
