BLAscHARD's BoIIER.-On the sth of September
Mr. Rugges. Canal Commissioner, made an expert
mental trip to Hayerstraw, on board Of the John

decided to recommend use Two week. before, the
beat was taken 10 Albany and back for the object Of
esccrtaning the consumption Of fuel more accurately
than can be done during shorter trip and the follow
ing was the result: The immersed section Of the boat
(, the length Of BEAM "a feet multiplied by the draft,
4 feet inches The velocity was 1913 miles an hour
The coal used from New-York TO Albany was: kim
ding coke and camel 40 lts.; coal to start fire,
900 fts; used while running, 490 lbs. Subtracting
Oh ibs, taken from the furnace after cooling the
total consumption was GOA lbs. The quantity OF
water evaporated 1885 lbs., or 1915 lbs. per
Is. ofcoal. The steam, on entering the cylinder was
super-heated SO' Fab.
GRAIs CLEANER, patented December, 1855, per-

Of New-York Ordinary smut machines are built of
weed and open the necessary consequence thai
they have 20 be confined in close room on account OF
the dust thrown out, and that they catch fire very
easily from over-heated journals. Several large mills
have been lost from TIL. cause; one in Owego last
year. the CALICO mill ut Richmond, Va, another at
Port Byron New-York. The rate of insurance on this
account is sometimes as high per cent. The new
grain cleaner has been devised to avoid dust and
Danger of fire. il entirely metallic and is all cncased
On vertical shaft cylinder, drum, about feet
in diameter and feet long, is keyed and mode to re-
volve at velocity of $50 revolutions Per minute On
the periphery Of the drum projecting fiat arms, de-
nominated beeters, are screwed in parallel circular
rows. They extend few inches outside, forming an
angle of 40 degrees with tangent to the drum, aud
their external surface measuring inches by inches,
Is deeply corrugated by vertical grooves quarter OF
Oil inch deep aud wide. Around this drum is O sta
stationary cylindrical envelope Of such diameter as
to leave scarcely an inch of free space between itself
and the ends of the bea;ers. This envelope is CORFU
gated circularly the hollow OF each oougation OPP
poritc OF bestars. This circular envelope is
closed below by a curved bottom terminating in

Of an horizontal fan blower which is place above IT.

machine There is also suction pipe leading from the
pipe at the bottom Of the machiue to the fan blower
To operate the grain is introduced at the top, between
the dunn aud the cylindrical casing Before 1t has
had time to fall inch, is caught on the inclined
face of beaer and thrown out by centrifugal force,
but the beater inclined as TO follow the grain and
exert upon il hard friction. The grain II
thus thrown into corrugaton of the outside envelope
and in falling down along the lower portion OF TINS

cesson Tie dust which is detached from the gram Is
carried up by strong current OF ar p'o"Ihg
inward between the drum and its envelope. After
reaching the bottom Of the machine, the grain enters
the central pipe and falls an inverted cone placed IN
H. and the last particles of dust remaining are carried
away through the outside pipe already mentioned
Machines Of this kind are built OF different sizes.
two-horse power machine can clean fifty bushels OF
wheat per honr and Is sold for 1850 Those Of larger
size cost propotionatoy lcss, and do more work tor

they are easily replaced by others, at cost OF - Tor
