Mr.. Emmons led Jack and Uncle Dick to what
practically MILL opening from the first. ''The
rollers used in this smooth and since there is
bran the MIXTURE their duty to grind into -four
of the requisite fneness This the first real grinding in
and ground and sed again and again the princ
pies that the bran until the finest grade of -four is
Chow do you know when it is fine enough'' asked
ground any more!"
s'Not There is such thing grinding flour
fine that all the life is taken out Of it, We have learned
by experience how fine ought to be- and while we know
pretty we'll when the machines have done the work, the
miers watch the -four very carefully Come here
to the window and I will show you what mean .
In the window board which lay little
pile of -four leveled off across the top. 49,
"Can you see any difference in color in that four!'
said Mr.. Emmons. Look real close,' he added Jack
started to shake his head. 49,.
"Oh yes'' said Jack, after moments careful scru-
tiny. tTheres little difference in the color every
'sJust about laughed MI. Emmons *tThs first
inch standard that up to the grade Of finest
-four The other inches represent the -four that has to be
worked less to bring it up to standard
s'You said you took the flour that sifted out of
the middngs purifier to make your best -four, Jack
said a, Mr. Emmons paused. What do you do with the
'We treat just like the first and it makes -four not
quite fine standard and which sold at lower
price, There u any about mill, he added
with smile. - -.
ct know they bran for feed, but do you up
every little, little thingi" Jack persisted :. .:-
''Every little, little thing,' repeated Mr.. Emmons
What not good for very good for beasts Even
the germ of the wheat, which forgot to tell is
during Of the early sftngs, made use of in
the manufacture of breakfast foods.' =. :-..
"But why ism It the germ kept in!' -.
Because it lowers the grade of the -four The gernt
which quite oily makes it Follower and it more
quickly This practically the process Of making
-four " Mr. Emmons said after short pause, while Jack
Dick watched the last sitting of the fine -four
There packing of the flour into barrels and sacks
still to be seen here, and then want you to to my
laboratory in the Offices because the work done there
very important part of the making Of four before the
wheat is sent to the mills at all = - 8
: "That reminds me,'' said Jack. What is the mill
dust that they said caught fire and exploded way back
in the seventies and destroyed several of the mills here
and killed eighteen men?''
Mr.. Emmons smiled again. Do you that man oveS
there sweeping up with whisk broom and dust pan9'
eyes, said Jack. =.
''That has nothing else to do all day long but to
20 the floor, sweeping the dust In ad-
dtion to his work. there what call dust collect
that suck up the -four dust that Sits out Of the
MACHINES carry it off to settle in enclosed space
That terrible mill explosion scared the mers they
have from it yet There isn't enough dust
