H.ziIros's DREDGiSG MacBSE.--There in on
exhibition at he office OF Hugh Downing, Esq, No.
&c Wall. street, amode OF an iuveaton patented by
Mr. James Hamilton of this City in 1852 which seems
well adapted to operating On son bottom when there
is deep water conveniently near in which the mud
may BE- dumped. The model consists substantially
Of a number OF scoops hung in nearly horizontal
posoa in frame which is arranged to DO raised or
lowered at pleasure, bet yeen two drmly connected
boats As used in lowering shoals and sand-bars, the
whole apparatus is to be towod b. a steamboat
backward and forward, discharging the dirt each
time in the deep water which is assumed to be adja-
cent. The forward end OF the fame is armed with
JOINTS projecting downward the effect Of which is to
harrow up tho bottom. Each scoop Is 50 connected
e the frame that its forward edge is capable of being
raised and lowered 10 considerable extent, forming,
when raised 10 a horizontal position, nearly water
tight box TO prevent the escape OF tho contents. A
few or tie whole OF these scoops may be thus brought
into ion at any given moment, the proper depth OF
water being indicated by long rod loaded with
suitable we sht TO dredge on the bottom behind. The
machine in it, present form was first produced 10y tho
inventor IN France, where ak were commenced acme
years ego under a government contract, to dredse
the harbor OF Toulon, bus he Revolution which de-
tb,oned Louis Philippe annulled the contract AMI
btggared the operators. The frames OF these ma
chimes were twelve feet By thiry-lye aud contained
each six scoops Ore was put in use partially in'
isbod and is said to have worked very successfully

in.on of Auburn " Y, whose rapid stave-cuter re-
ceyed les, wear the highest award of the Crystal Pal
ace Exhibition, has lately Introduced machine for
ointing which in novelty and interest fairly seems 20
excel IT, This stayeIonter, which WAS patented In
October 1853. Joints the itayes entirely by saving
and Il means by which The proper swell Is given to
the bge and The proper Devil to the edges of slaves
of any width, make this an otject Of considerable
curiosity. A narrow staye may be succeeded bya
wide one and this again by ono extremely narrow
single and easy motion Of n lever supposed TO DC
always held in the left hand Of the attendant being
sufficient to adapt The parts in every respect. The
saws two in number, are circular, and mounted side
BY SIDE, although separate shafts or srbors. Each
arbor il carried In bearings On movable carriage,
30 that the saws may DO made to approach or reccde
from each other Tho motion Of the carriage IS con-
hoIled by grooves bent vertically in such manner
that the save would M face 20 face, il brought quite
together, but become Inclined they separate, tho
upper points being always nearer than tho lower.
Fhese two carriages are connected by links to the
Aforesaid lever that they approach or recede sim
ultaneously from which ii follows that whatever their
distance apart the Devil in which they cut is always
closely approximatiDg to that desired. The method
by which the blge swell in the middle Of the stave
i. produced is perhaps still moro admirable, it being
perfectly selfa6usting. Thelevcr, and consequently
the position OF the scws being held stationary during
the iointDg of stave of any given width II tho wood
was fed up in rectinear line, il would be sawn in
the proper Devil, but OF equal width throughout.
The means by which tho proper swell In tho middle
is attained in this machine 10 simply that of allowing
the staye To- be moved forward in curved rather
than straight line. The feed apparatus is in fact
species OF endless CHAIN the links being equal to that
OF the lorges stave required andthe wood being
held between hooks on the Inks which tighten by
their own motion. The joints or hinges OF the chain
being carried in guides nearly horizontal but curved

the saws the staye il in fact chord of an arc, and
the middle passes the saws at a lower point, and
where the saws are wider apart than do the ends
By properly proporionng the curve given to the
guides, any amount Of swell may be given, az re-

the proprietor to make from 200 to 900 bTres Per
