''That is practically what we do to get the dirt

the sieve 'separator' however, He stopped at tall
machine which stream wheat was being constantly
Ted, and of which part kept up incessant shake
shake, shake.
''There several seves here, made of perforated
metal, he said in to Jacks questioning eyes.
top you see, has quite openings This
lets the wheat and the small seeds drop thru the finer
sieve beneath leaving behind the cha the pieces Of
straw and the seeds, like barley, wild OATS etc
The second sieve has holes too small for the wheat to
drop thru and it stays behind while the tiny seeds of
wild mustard weeds and the like fall away from it, Take
handful out of the top before it is cleaned and
pare it with this clean wheat have taken from the bot
Jack did as he was told ttwhy,'' he exclaimed,
when the two handsful placed side by side That
certainly is most surprising: When saw the wheat
threshed out in, the field, it looked clean''
eve don't call it clean, yet," said Mr. En-
mons From here it goes thru Of those spouts to
huge cylinder where it is whired around rapidly and
busted with brushes and then passed to another cylinder
and whirled around again with paddles that throw it
against the sides of the cylinder to of crape Clean
and then it is famed by small whirlwnd until it IS
actually free from dust and grains of dirt. When
get wheat that shows traces of smutdo know what
smut isl" he interrupted
Jack nodded and Uncle Dick said ~ guess the boy
is pretty well posted in wheatoogy until the grain
rves at the ml.''
tTWhen we find smutty wheat in our lot, we have to
wash it, in addition to all this cleaning"
'What chemicals do you use9'' said Jack.
eve use no chemicals at all. Just plain wster.''
Jack turned to Uncle Dick. "You told last
spring. ddn YOU that when the farmers cleaned their
grain Of smut, they used chemicas7,
right for them to chemicals grain they going to
put into the ground but wheat that is to be ground direct
y into -four could not be treated with chemicals because
it would poison the -FOUR
-. tfOh!'' Jacks only comment, and Mr.. Emmons

'To get the best results in the crushing process the
wheat must be of the temperature before it goes
the first set of rollers &c. after it is made perfectly
clean and moistened little, the bran will not be
dry it will crumble into little pieces at the first crush
ing it into those cylinders there, and carried
steamheated tubes inside, that look very much
like steam radiators From there the moist wheat
goes to bin, where it stays pretty nearly hour to
get tempered call it, of the same temperature
thruout the lot At the end Of this time is ready for
the first crushing We shall have 60 down to the first
floor to see that -: -. -. -. .--'~-.
- ''It must take very strong machine to grind the
berry, said Jack their way down. - = =. - =:
q does, said Mr. Emmons, ''but want to correct
you that word grind. We crush the berry in the
first process instead Of grinding it, Flour must not have
any bran in it. # we ground the berry hard the first
thing should break up the bran into small PARTICLES
and could not separate bran and flour after each
crushing. ... >.,...
'These rolls that handle the bran until all the flour
is sfted out of it, have them to prevent actual
grinding" Mr.. Emmons opened the box enclosing the
rollers and brought out handful of the first crushing
ttYou see' he said holding it out to Jack the berry
is just Of crushed open gently leaving the bran in
large pieces. There little fine flour dust Also but note
how big most Of the white pieces This mixture Of
-four and bran call first break stock From this
chine the break stock goes into elevator in of
those big square tubes to the sixth floor The elevator
by the way, consists of little buckets belt On the
sixth the first break stock goes machine called
tbolter where all the finer flour particles sif out and
left behind while the bran is sent down to this
ond machine here" $500
''I should think it would have to be pretty fine
wire sieve to do that work, " remarked Jack
ooh it ism It wire at all, - exclaimed Mr.. Emmons
GIVE what called boiling CLOTH, very expensive
weave made entirely of silk and used almost exclusively
by mers But to return to the bran The gooved rollers
of this second machine crush the berry little and
then the second break stock goes again to the sixth floor
to another bolter the fine -four Sits out and the bran
back to this third machine for another crushng
stPlease wait minute, said Jack t'until I get
that just straight 1t is crushed into first break stock
in No. machine sent upstairs and the middngs finer
-four sifted out down to No. 2 machine for an
other crushing goes up again for another sitting and
comes down for third crushing That is after each
crushing break stock goes to sitter and the mddlngs
drop out Is that right" Mr.. Emmons nodded.
