The Editor of the Boston Eccniag
transcript gives the following account of
.he enterprise, IA hl, journal OF the 5ih lust,
ai1cr personal visit to ,he works IA tins
city, where the machinery Tor the new Ca
.ouc ship Is being butt, aud where also a
sAty horse power irial engine Is ~ opera
ton on tins new principle Tor the produce
uon of motive power.
Tho idea OF substituting a new and SUI
peror motive power for steam will no doubt
strike many minds as eXtrayagant II not
cHmeuca We have been 50 accustom-
ed TO regard steam power as the ne Plus
Ultra oI attainment "a subJecling the modi-
he'd forces OF nature To the service of maa,
Ola, discovery wich promises 10 super
eede tAis agency, Will have to contend
,ainst most formidable preconceptious, as
sell as with gigantic interests. NerefIhe-
les, II may NOW be predicted with CONN
deuce that We are on the eve of another
great revolution, produced by the applica-
! ton Of an agent more economical, aud m
'aculably safer than steam. lew years
I hence and we shall hear of the wonders

II 10 the question How did you cross the
Auanucl the reply will be - by caloric, ct
A course ! On Saturday | visited the manu-
4 hcloty, and had the privilege Of inspecting
Lncsson's calonc engine of sixty horse
n power while Il was Ia operation. Ii consists
h Of $50 pair of offenders, the workin plstons
Il o. which are - inches ~ diameter. Its
great peculiaritles are IT'S very large cylin-
defs aud pstons, working with very low
| pressure and the absence of boilers or
heaters, there being no other fires employed
'nan those IA small CRATES under the bottoms
o. The working cylinders During the eight
months that this test-engine has been IA OPP
e'a'ion, not cent has been expended for
4 repairs or accidents. 1t Is beautiful and
a imposing object, and conveys the idea of
II power aud symmetry much more impress
| sNeiy than the largest steam engine that /
nave ever seen. The leading principle of
tue caloric engine consists IN producing mo-
i've power by the employment of the expan-
Eve iorce of atmospheric air instead OF that
s'eami the force being produced by com-
1 P'ession OF the air IA one part OF the ma
.u'he' aud by ITS dilatlon by the aPplica-
non OF heat IN another part. This dllata-
'"n' however, is not effected by continuous
|rPplcalon of combustables, but by pecu-
lunar process of transfer, by which the Ca
"c Is made to operate over and over a.
1 VA, VIZ the heat of the air escaping from
Y" working cylinder at each successive
'oAe OF the engine Is transferred to the
'u, compressed air entering the same, SO

only necessary IN order TO make good the
'Ses OF heat occasioned by the unavoIda-
e radiation Of the heated parts of the ma
pune The obvious advantages Of this
ea' improvement, are the great saving OF
- aud labor IN the management OF the en-
f"e, aud It's perfect safety. A ship carry
Tue amount of coal that our Atlantic
gamers now take for a single trip, could
Us and recross the Atlantic twice with

Il :" the best fuel for this new engine, we
ual no longer be obliged to purchase btu
