Close of the Fair.

The Annual Far of the American Institute
closed last evening with an Address by Gen.
TALLMADGE and generous award OF Premiums,
of which the most important will be found IN
another part Of this paper The attendance was
probably greater than at any former period of the
Fair We paid last visit to the department of
Inventions and Machinery in motion. Of which we
must say few last words
Gacynne'S Pump-Prof. Hare of Philadelphia,
ex-Afayor Clark Chief Engineer Carson and 9th.
ers were among the crowd assembled in the ma
chnery room to witness the operation of Mr..
GTynne's Balanced Centrifugal Pump as fire
engine The power employed was some six
horse, whereby column of water four inches in
diameter was raised from the Bay, carried through
long sections of Hose and elected with great force
through four scparate nozzles, each an inch in di
ameter. We doubt that City has any four
engines which, with quadruple the power, could
deliver so much water Afterward the hose was
taken off and the Pump worked as simple ele
vator, throwing off raging, foaming body OF water
like mill-tail. We understood Mr.. G. to say that
this machine had pumped 500 gallons per minute,
which we should think not above its capacity.
For emptying Dry Docks, reservoirs, draining
marshes, &c. we believe it has no equal in etiii-
cheney, while its adaptation to the eXtinguishment
of fires is not less complete The principle that
of applying the centrifugal force OF water in rapid
rotary notion is susceptible of universal applica-
ton, and we trust it will Immediately be consid-
cred and adopted in the construction OF Fire
Engines.
Smut Machines-The first Premium for Smut
Al ,1o,1&
who has taken the first Premium at several Fairs
this season. 1t is admirably designed for freeing
grain of all kinds from smut, dirt, any foreign
substance, and has been adopted by many of the
best mills in the country 1t is simple and cheap,
and Mr.. Smith estimates the cost of cleaning
grain with it at three ou1ths of cent perhundred
bushels.
Ship Tcnh1Mion.-We learned with pleasure
that q Gold Medal was awarded to Jannson for
his machinery for ventilating sea-going vessels,
which was exhibited and warmly commended by
President Taylor in his closing Address. This in
vention may be fairly said to provide ship with
lungs as the slightest roll or lateral motion OF any
kind forces out (by the gravitation Of water
column of the air or vapor in the lower hold OF
the vessel and introduces by atmospheric pres
sure pure air instead. That invention applied
to all immigrant passenger ships, would save
hundred of lives per annum.
Ventilation Of School Rooms, e5'c-Ransom
Cook exhibited capital model of a plan for ven
tilating school houses, prisons, hospitals, and all
other buildings, especially those apt to be crowded
or long closed. Mr. c. has taken out no patent
! but invites all who will to use it without
charge 1t is but an ingenious taking advantage
Of the fact that warmer air will always ascend
into colder when it is permitted to do SO; but 1t
should be examined by all who contemplate build
ing, especially for public uses.
OF Baak Locks we noticed two now to us-one
Jennings's combining great safety with simpli-
city, manufactured by Arowsmith L Co. As Gold
st. Of Iron Carriages, there are two or three bo-
side one already spoken of-Patterson's, made by
Allen Moody, Troy, seems in some respects SUI
perior.-There are also rival Sash Balances,
that seemed fair by w Chase, Buffalo sold at 1872
Broadway. OF Crates and Tenders, there were
many tasteful pattems-we liked those of w. i
N. Jackson, 238 Front-st. But we must break off
here, leaving few notes over for further observa
tons.
