There is not 20 great a variety Of operat
ing machinery, as has been seen at some 0
the fairs of the American Institute; bu
The samples of all that is elegant, excel
len, and useful of American manufacture
ers, surpass in variety and quantity, any
thing hitherto witnessed on this continent.
To notice one>twentieth of the articles ex
biblted, would be q task far beyond nv
present convenience or inclination. But
Of those which were most interesting to
me, | may mention first, the steam-engine
by which The operating machinery is driv>
en-. 1t was built by Pool & Ferguson, of
Baltimore, rated at abou! 20 horse bowers,
and furnished with steam by an upright
boiler. The principal peculiarly about
it, is its superior style of finish, and the
smoothness Of its noiseless operation.-
There is not the least putting, CATERING
nor jar; and q person might Stand within
q few feet without knowing whether The
engine was in operation. An excellent
Ioom and spinning jenny are in operation.
out being Of common classes, they excite
but little attention. Near them ia a Gus
rious m1chine for combing and spinning
hemp, forming it into uniform rope>yarns
by one simple operation. This machine
was invented or exhibited by Moses Day,
of Roxbury, Mass, and not only displays
much scientific ingenuity in lis cons,ruc-
ton, but exciles admiration by the p~erfcc>
lion Of its straig ht-forwarG self regulating
operation. Benson's 'Watefsram' is here

to- invite people 10 cali and examine its
utility. Among the operating machines,
one Of the first in importance, is Mr.. E.
Howe's Sewing Machine. This machine,
though not complicated, performs Won
ders. 1t will sew straight or curved
seams with equal facility, ard as rapidly
as nine %tajtors, while the seams thereby
produced, land of which we procured a
specimen are superior in strength and
regularity, 10 anything that can be done
by the ordinary needle. OF agricultural
machines, the greatest variety is exhibited
by ]. Murray of Biltimore. Among
these is a corn,shelling machine which
~excells all others in the perfection OF its
operation. 1t is calculated 10 be worked
principally by hand. and not only shells
rapidly and thoroughly, but by means of
an ingenious but simple appendage, it sep.
ara!es the cobs and chaf from the clean
corn. 1t is probably the ne pluJ ultra in

Disers, of Gettysburg, Pa, meets with
unusual commentator, and The inventor
