DESCRIPTION OF CLIFF-CRANE for the RESCUE OF PERSONS SHIPW

The machine which is the subject of
the present notice is especially appli-
cable to such parts of our coasts as con-
sist of abrupt and perpendicular cliffs,
washed by the waves, which preclude the
possibility of rescuing any ill-fated ma-
riners that may be stranded at their feet,
except by mechanical means from above.
A most important consideration with re-
spect to any machine contrived for such a
purpose is the absence of all ihat is com-
plicated; simplicity of construction being,
doubtless, the surest guarantee for suc.
cessful operation. This will appear the
more evident, when it is borne in mind,
that if ever called into action, it would
probably be amidst scenes of confusion
and distress—perhaps too in the darkness
of the night. . In such cases it too fre-
quently happens that more zeal is shown
than discretion-all are eager to lend a
helping hand, but few aware how assist-
ance may best be rendered; and under
such circumstances, complicated tackle
of any description might not only render
abortive the means of relief intended,
but in all probability lead to fatal re-
sults. Against these fearful contingen.
cies, the inventor of the present apparatus
appears to have effectually provided.
Simplicity and power are at once com-
bined in this machine. There is nothing
to adjust, which can lead to confusion or
failure, while no less than four indivi-
duals at a time, may with ease be raised
or lowered in the carefully-constructed
cradle attached to the machine. Nor is
it in saving life alone, that Mr. Johnston's

Property as well as human beings may
be rescued from destruction by its simple,
