MANS Monthly COR January, Of EricsSon's Ca
lorc Ship, will not be uninleresting to our rea-
ders:
The invention of new motors has always
been source of fruitful inquiry. Many in
cenuus and useful applications Of mechanical
force have been contrived for the one great OBJ
iett-ihe propulsion of vessels upon the ocean,
and of carriages OIL the land, by means of
rowcr, which, possessed Of the force oi Steam.
should be at ouce more economical, less dan.
gerous, and of more easy and general appica
ion, To effect this Obj oct, skilfu meChanists
have directed their attention to the development
of those powers of nature by means of which
man connuers the world 10 his will. There is
much that is curjons in the thought, that 50
simple an agent as water, when subjected 10
the action or heat, should create an instrument
ca pa bic of revolurioniz'ny commerce, aud OF
bringing the ends of the earth together. Tie
is something much more remarkable, if tie
idea can De carried 10 perfection, OF which
there seems now but little doub', in the en-
pnymcnt of the air we hc1'he, and without
which we cannot live, To feed the lungs Of the
iron monster, which conveys US rapidly from
port TO port, and serves to spread abroad and
strengthen the ties of civilization.
The Caloric 81 ij OF Captain EGIcssos marks
a new era in the history Of navigation. An
experiment it can scarcely be termed, for It is
the result of twenty-five years Of research and
experience. Its triumph or its defeat will set
tie question which has attracted the attention
of the world. and It's final issne IS to determine
the future of ocean navigation.
