but wherever we chance to stop, we will vouch 70

3-Two small revolving printing presses, opera
ting, either with cylinder or platten. The peculi
ary of the press consists in the manner in which the
forms are transported and brought alternately under
the platten cylinder. The beds at their extre
mites are thrown into a curved track-acting as
counterbaance TO each other, and In great degree
preventing the jar occasioned by their momentum
In the platten press the sheet is inverted and print

the most exquisite hneness, but beautiful polish,
which no other machine can do. Additional inter-
est is given to this machine when we recollect that
its inventor James Bogardus, Esq, OF this city, is
the Individual who won such distinguished hOnors
few years since in London, by the invention of
the metallic engraving machine, and the kaleida-
SCOPE engraver, by which bank note engraving
was made-a fac smile of which could not possibly
be produced even by the same machine with the
same operator Another circumstance in that gen.
tleman's history transplred at that time, to throw
better light upon American genius. The Penny
Post department offered premium for the best plan
OF issuing and affixng stamps Our distinguished
American measured his talents with thrty-six hun
dred compositions, and was successful. The sugges
tons which he then made to the department are at
this day adopted to the letter. One other OF his in
ventons, not before the world, though perhaps the
most important OF all, is die sinking machine, by
which die may be produced by machinery giving
to it absolute perfection Only three specimens OF
it are in existence, (which is for the gold med

combines the following advantages:-The bed is
driven by such means as to give to its motion the
most perfect uniformity, preventing the least tremb-
ling, however deep the ''cut;" the motion of the
bed is one-brd faster backward than forward; the
tool holder (selt operating) so constructed to
work in every direction, planning horizontal, vert-
cal inclined, concave and convex surfaces. The
method of holding down the bed, of cleaning and
oiling the ways, is entirely new. A visit to this
machine should not be omitted
IL" Progressive Steam Pile Driving Machine
operated by small steam engine, Capt. S. Cram,
inventor. This pile driver is so constructed, that
when the pile is driven, saw Is put In motion
which cuts it off at the proper level, and thus makes
it part OF the foundation for the machine at its
next step forward.
l2.-At the farther end of the room, the spec
tator is brought to an agreeable pause in front
of one of Stllman u Co.'s unrivalled steam
engines. This engine, OF which we have
before spoken, is OF twenty-five horse power,
yet occupying butttlemore space than pianoforte,
and answering every requisite Of that instrument,
excepting music-unless it be the music of grace full
motion-for of noise it makes none. Substantial
and beautiful as this Is, we are assured that it
is not above the most ordinary of its pattern pro-
duced at that establishment, and that it was but
few days since appointed, from among number
already sold, to fill its present enviable station. At
tached TO this engine is an adjustable Expansion
valve," the invention of Horatio Allen, Esq, the
able engineer of the Croton Aqueduct Commission
ers. Mr.. Aliens object has been to obtain for To-
connective engines an expansion valve which could
be adjusted without stopping.-for instance, when
the engine is upon ascending grade, and requir.
ing the maximum effect of the boiler This object
he has well attained
l3.-A further acquaintance with the Dynamome-
ter induces us ag ain TO refer to IT, IL has been aced
in its present position by the Institutes for the pur
pose OF measuring the power required for the opera
ton of machines exhibited. Without such an in
strnment no machine exhibition canbc perfect. The
value of machines generally depends essentially
upon the expense of mechanical power necessary
TO propel them yet this power has necessarily been
tested by CONJECTURE by uncertain modes of COM
putation but little better, the consequences of which
have often told upon the success of those whose
fortunes are embarked in mechanical enterprise.
deslderatum of such importance Is supplled bv
this instrument. Ii will test the power Of a steam
engine or water wheel direct, which no other ever
mas done and all is done with extreme accuracy,
on principles purely scientific, and by combna-
ton extremely simple. 1t is not patented, but is
claimed az the Invention of Charles T. James, New
buryport, Mass, and constructed by Bancroft, Pro-
whence, K. !.
