lhave formerly existed against this species {
motive power. The principle of application o
his machinery is radically different from that @
other parties who have tried powder and hav
failed in adapting it to this use. 1t has beef
calculated that the saving of expense on this en-
gine, over the present steam locomotive, will b'
some ninety per cent. We may at some iutur
time, give general description of tho machine
and the result of certain enquiries into the ap
plicability of the power.
Another invention prominently before the pub
lie is the Electro magnetic Engine of ProfessO
Page, lately on exhibition at the Society Library
Rooms in New York city, where model engines
Of six horse power have been explained and ex
amined by capitalists ond others. BY the intro
duction of electro magnetism, it is claimed that
cheaper motive power, oi equafemciency witt
steam, is secured. Of the truth of this asscr.
tion, TIME and experiment will have to decide.
Those who have read former numbers Of our
paper, will have some idea of the efforts made
by Professor Page, and know as much as we do
of the probabilities Of his success. Mr.. Pages
early experiments attracted the attention of the
Hon. Thomas II. Benton, very sagacious aud
eminenlly practical man, and, through his inhu-
ence, Congress appropriated some twenty thous-
and dollars in aid Of the experiments.
Another plan is that of Errickson's Caloric
Engine, which is propelled by the rapid expan-
sion and exhaustion of atmospheric air by means
of heat applied directly under the working CYL
inler. The construction Of this engine is sim.
pie and substantial, and the cost Of running it is
said to be only about ono-third that Of the com,
mon steam engine. The air is rapidly expanded
BY means Of radiators of wire, and exhausted
under immense valves weighing nearly twelve
tons in the machine Of 60 horse power now work
ing in New York. 1t is stated by the inventor
that air is readily condensed from G31 degrees
Fahrenheit to l3l in the fortieth part of one
second, and the caloric Or heat is retained 10 aid
in expanding the next charge, thus causing a
vast saving Of fuel. There are two engines or
this plan of 10 horse power, low pressure, ant
one of 60 horse power, high pressure, beside &
small model sent to England for exhibition a
the Worlds Fair. The inventor is making ar
rangemcnts to place his engine in large shiE
for trial of its marine qualities.
Still another plan is that of the Static Pres
sure Engine of Messrs. Sawyer and Gwynne
in which the compression of atmospheric air il
proposed to be made effective by the ntroduc
tion of centrifugal force as an auxiliary agen
or power, the initial moving force, or amospher
ic pressure, and the auxiliary force both actin
on non elastic fluid or water, which is used a
the med dium of motion. IN the two FIRST arrange
ments, it is claimed that power can be maintain
ed ut much cheaper rate than heretofore an
in the last named plan, 1t is asserted that pow,
to any extent may be maintained free of all CO
beyond mechanical construction, which is vel
simple, and fabrication. The two first are
operation; the last named is yet to be made
go-the construction Of working engine beir
now rapidly urged to completion.
AT Cincinnati, Mr.. Solomon is working su
cessfn ly carbonic acid gas as cheap and eff
cient motor, while the friends OF steam are CO.
stantly improving their arrangements to econ
mise fuel, friction and wear.
1t can be hardly possible, that with so muc
thought, genius and practical talent, as is no
pursuing the general subject of new motif
power, we can fail in finding something tn
will either supersede the present steam engin
or at least find some Improvements that will re
der it vastly more available in cheapness ar
safety. Indeed, says the New York Tribun
it seems that the seething brain Of inventiv
genius was never more active than at the pre-
ent moment, especially in this country, and ou
triumphs at the Worlds Fair will not be like
to weaken inventive effort here or elsewhere
1t seems that we are on the eve Of grander d
valopements in humanity and natural scenc
than any hitherto achieved by man. In the
matters, Excelsior !" is our most appropria
and stirring battle cry, as the car of progre
rolls on TO successive triumphs.-RdI NJ
