dIl duiulAtuTc OI CONSIDERABLE wafer we
were washed, and whizzed dry, or nearly
so. Leaving this machine we entered
box containing conveyor, at the head of
which small stream of water was al
lowed to mix with us, and we were sent
to steel tank to temper, as the miller
called it. He meant by that that the ber-
ries must be allowed time enough to alb
sorb the small amount of water he added,
even into the heart, and thereby undergo
certain chemical changes. He said, also,
that the reason so many millers cannot,
or do not, make good -four is because they
fail to clean their grain properly and then
fail to allow the moisture to penetrate be-
yond the bran coats. These, and many
other points shall relate, I learned by
keeping my ears open when he was de-
scribing the methods to visitors and custo-
r,ers.
After lying in this steel bin for two
days we were again sent to the cleaner
and on through the scourer, where the
loosened flakes of bran were secured off,
as before, and we were sent into another
bin. Here we passed through machine
that governed the amount of US that
passed to the milling machines, called
rolls. And now our bodies were broken
up and the various parts sent hither and
thither throughout the whole system to
emerge at last as -four bran, shorts, and
other grades of mill products.
As we plunged through the governor
we entered boxlike receptacle at the bot
tom of which was a huted roller that
carried US out and dropped us in steady
stream between two chilled iron rolls, one
of which revolved several times faster
than the other, although they both roll to-
ward one another. The reason for this,
I heard, was that it gave shearing action
in breaking the berry and produced fine
sharp middlings, which later became the
best grades of -four. After being crushed
here we passed onto very swiftly vi
brating sieve where the coarser chunks

lowed to go to the fne-meshed silks to be
separated into -four and middlings that
needed further reduction work before they
would be -four.
The coarser particles were then sent to
another set of rolls, where the bran and
flour were scraped apart by the action of
the fast and slow rolls, and both were sent
to the silks to be separated, the -four pass
ing through and the bran being delivered
at the tail of the bolter; the middlings
uniting with the tailings of the silks pre-
ceding. Both of these middlings were then
delivered to a set of smooth rolls, revol-
wing as the others, but depending on a
heavy pressure to achieve their work of
Aattening the chunky middlings into
proper condition. These were sent into
another set of boiling cloths or silks, as
the miller called them, to be sorted. Again
the -four went through the fine meshes,
and the fine, gritty middlings, almost pure
-four, were separated out and sent to an
other set of rolls, while the small parti-
ces of bran, with other fibrous particles,
and including the oily fakes of the germ,
which never would become -four, were
tailed off, as brown shorts, or standard
rniddlings.
These fine middlings now were sent
through another set of smooth, or reduc-
ton rolls, for a last time, and then on
into another set of silks where the -four is
passed through, the taiings being grav-
ish product called Red Dog, White Shorts
or Flour Middlings. In some systems of
milling the bran and the. shorts are sent
to machines called busters, where they are
,vhirled rapidly, in cylinder coated with
wire cloth, by revolving brushes, the Aouiy
portions sitting through the screen, being
removed by revolving brushes on the out
side; the houry part being sent to
