REMOVING METALLIC SUBSTANCES
FROM GRAIN.-The introduction of
grain-binding machines employing iron
wire to bind the sheaves very quickly
led to the discovery that the bits OF
wire, cut off each time sheaf was
bound, caused great deal of trouble In
the after process of grinding. The
ends of the wire mixed with the grain
reached the mill only to break and
scratch the stones and machinery, and
70 produce friction and heating that
sometimes resulted In setting fire to
the mill. So serious became this mat
ter that the millers objected to receiv-
ing any grain bound In machines using
wire. Fortunately, the difficulty has
been surmeunted by the introduction
of appliances for removing the bits of
iron from the mill. Experiments show
ed that a common magnet hung in a
graln-spout would catch and retain par
ticles of metallic substances mixed with
grain. Several methods OF accomplish
ing the same results are now in use In
western mills, and they may be divided
into two classes; those using perman-
ent magnets and those using electro
magnets. 1t has been found that a

cient To arrest every particle OF magne-
tic metal, from pieces of wire several
centimeters long, down to iron filings
and metallic dust. The usual plan is
to saw off portion of the top of the
spout and to divide 1t into three pieces
and cut holes in each piece for the legs

a row across the spout. This gives
three rows of magnets placed directly
or diagonally across the stream of grain
the diagonal position being considered
the best as the grain is driven from side
to side IN passing, and brought into
close contact with the magnet. The
magnets may be lifted out of the spouts
in groups of four by taking of one of
the covers, and may then be cleaned
and put back without disturbing the
others. Another method of hanging
the magnets is to cut three slots across
the spout, and hang the magnets on a
rod with blocks between them to keep
them in position. Ey this arrangement,
the magnets may be removed one at
time, enough of them remain 10 keep
up the work while the others are being

magnets is easily brushed off, two
clearings in a day being found sufficient.
By employing bars of soft iron in con-
nection with coils OF wire and bat
terry, electromagnetic may be used, and
in lifting out the magnets it will only
be necessary to break the circuit, when
the metal adhering TO them will Instant
ly drop on. Another form of appara-
tus employs horseshoe magnets, having
paper or wooden filing between the
legs, set upright on the ends of arms
revolving horizontally in a circular
tank, very much after the manner of
some forms of miXing-machines. The
grain is delivered at the edge of the
tank, and is pushed by the revolving
magnets toward the center, when IL es-
capes through an opening in the bottom
of the tank. Another device employs
a series of permanent magnets and
travelling apron for conveying the grain
away after il has passed over the mag
nets. The only advantage of the use
of electro magnets is in the facility of
cleaning them by breaking the circuit
and demagneting the iron. By sulta-
BILE clock work this can be done auto
matically, provided there are appliances
for shutting off the grain and for catch
ing the metallic dust when the magnets
are thrown out of action.
AVOID giving Il tired horse very cold
water, rs it often produces collie. In
large establishments exhaust steam is
passed through the horse trnughs; 9TH
ers allow the water to stand Tor some
time in buckets. On the road horses
should be watered once in ten miles at
least. The stomach of a horse is so
small in comparison to his body that
large draughts iujuriously dlstend it;
consequently, small quantities at regu-
lar intervals is the best rule.
IT is great mistake to keep cattle
stabbed all winter and then turn them
out in spring, exposing them to cold
storms of wind and rain. Stock esDe-
cially dairy stock, and all animals Civ
ing milk, should be carefully protected
in the spring until the days and nights
are warm
