HOT AR Az 4 MOTOR.

sons final success is sill received in some IN
fuential quarters. There is nothing essential
ly improbable in what be Claims, and what al
intelligent men who have examined the sub
ject believe. that he has accomplished he
processes TO use very simple and weu-knowa
sgency, namely the expansive power Of air
acted upon by heat That there is such s
power no one can deny. IL is as familiar as the
power OF water when similarly acted upon.
We know that steam is used to drive machine
"; WHY. then, refuse to admit that bot air
may be used for the same purpose Or AZ
least why reject, without examination, the tes-
tinOny Of so many judicioss and cool-Inindet
men. who have looked at the matter, and al
firm thar the Hot Air Engine is actually built
and ready 20 work with greater cheapness
than stesm ard perfect safety Why should
our great steamboat owners and shipping mer-
chsnts longer persist in the notion that the
whole thing must be entirely deluSion
After dl. there is nothing surprising in the
continued doubt The grander the character
Of novel principle or newly discovered agency
the more certainly do the mass of men receive
it with distrust We accept the news Of failure
without hesitation, but the intimstiOns Of suc-
cess we are slow TO eonfde in. Had the jour
mails reported that Capt Ericsson had aban.
dOned The hot-sir engine in despair, everybody
would have believed il but when told that it
is triumphant, that il answers every glowing
anticipation Of its author, we dOubt, and doubt,
and refuse to be convinced till We can refuse
no longer 1t is too good to be true, is our in-
stnctiye reflection. The triumphs OF genius
and science are held to be impossible till they
are achieved. We recollect that Morse's Tel
egraph vas long pronounced impossible, and too
good 10 be true
The mechanism by which Capt. Ericsson
controls the expansive power of hot air is
marked by all the originality and simplicity Of
genius. As is the case with most great in
yentions, the wonder is not that il should
accomplish the end, but that it was not sooner
hit upon. In studying the machine, each part
is found so perfectly adapted to its purpose,
discharging lis function with such economy
and certainty, the principles are 20 clear and
the arrangements so felieitous, that it seems
rather spontaneous creation than the pro-
duct Of long years of laborious thought and
gradual improvement The supply cylinder,
or great air purlp, charging itself with air from
the atmosphere, through it's valves, as the
descending stroke Of It's piston leaves vacu-
um; the reservoir of compressed air kept full
by the upward stroke OF the same piston the
valve that opens and allows this compressed
air to rush into the heater the regeneration
which takes the heat from the air that passes
out, to restore il to that which goes in, thus
using the same heat over and over again; the
cutoff which ntervenes at just the right mo-
ment closes the valve that admits the COM
pressed air into the heater; the contrivances for
con6niDg the heat TO its place, and enabling
engineers ard firemen 20 work convent
ontly and in comfort all these features
are so beautiful, so free from complicated
contIi' ances, and so admirable in every re-
spect that il is impossible for the mind TO
grasp them in all their relations without salts
faction ard delight. Here, indeed, i. the pro-
duction Of mastery genius, to which science is
ancillary and nature obedient 1t has lately
been said that for general to think rapidly
and wisely on the field OF battle, to use every
circumstance and anticipate every conse-
quence amid the rustic Of bullets and the h0r-
rors ofcarnsge is great intellectual demon
stration, aud it is true. But how much greater
and nobler the Intellectual action which con-
tends with the elementalforees and in conquer
ing endOws man with new mechanical agent

comprehensive, more sublime, more intrepid,

iucredulity Of the world is prolonged little
further or not. He is sure that the true merits
OF his invention viii presently receive a uni
versal recognition. IL will be admitted FOR all

his recompense ofhonor will not De withheld. A
power which by itsTeateF eheapness supplants
steam, While it is free from ali danger, and can
be adapted TO perform the simplest domestic
and agricultural labor is sure of a ready and
grateful abortion. But We should Ike 10 see
little more cordiahty toward il on the part of
those most largely interested in navigation and
commerce.
