ties Of the -four produced
Tho yield Of -four obtained from tho
Turkey variety cut with the harvester
In 1910 was 72.G5 per cent OF the
whca, while the yield OF -four oh.
tainod from the wheat cut with the
binder and stacked was 7277 per cent
Tho yield OF -four obtained from the
kofod wheat cut with the harvester In
1910 was 72l7 per cent. while tho
ylc'l Of fiour produced from the wheat
cut with the binder stacked was ~ ~
per cent II Is thus readily seen that
with respect TO the yield OF the -four
the method OF harvesting has no In.
fuuCncc whatever. II is interesting to
note, however. that greater per cent
OF high grade flour may be obtained
from the Turkey variety Of wheat.
About eighty per cent. OF the -four pro.
duccd from the Turkey wheat would
be classod as high grade -four. while
only about forty per cent OF the -four
produced from the Kofod would be
2lasFcd as high grade.
In case Of the chemical composition
OF the -four obtained. no conclusion
can be safely drawn regarding the in.
! nuence Of the harvester. In case OF
the Turkey variety Of wheat. the -four
/ produced from the wheat which had
boon stacked Ia slightly higher than
/ that OF the -four produced from wheat
cut with harvester. In case OF the
Kofod variety OF wheat. however. this
IL not true. The Kofod wheat cut
with the harvester In 1910 has a slight.
/ ly lower protein content than the
same wheat cut the same year with
the binder and stacked However. the
wheat cut with the harvester In 1909
has higher protein content than that
cut with the binder and stacked. The
chemical composition OF the bran and
shorts indicate only that these mill
products srO rich in protein and would
probably he good cattle feed.
The volume OF the loaf produced
from the Turkey variety cut with the
harvester was 1869 &C. and 1868 &C.
In 1909 and 1910. respectively. while
the volume OF loaf OF the bread made
from the -four produced from the Tur.
key which has been cut with the
binder ant stacked was 1857 &C. In
case OF the Kofod variety. these mum.
bers become 1876 &C. and 1850 &C..
respectively, for 1909 and 1910. and
1894 &C. for the wheat which had
been stacked. The -four was all treat.
ed under uniform standard conditions
and II Ia thus seen that II any infu.
ence can be ascribed to the harvester
at all It must be favorable influence.
While the investigation did not
show any Influence OF tho harvester
on the bread'maklns value OF the -four
produced. II did demonstrate the value
Of Turkey Red wheat for -four produc,
ton. The Turkey Red wheat produces
a uniform -four OF high grade which
has the strength 10 produce a loaf OF
bread OF good volume. Tho -four pro,
duced from new Turkey Red wheat
seemed TO mako as good bread as
-four produced from old Turkey Red
wheat. while the -four produced from
new Kofod wheat produced loaf OF
bread very much inferior in quality
and yet the yoar-old Kofod wheat
produced good -four, Actual photo
graphs OF the bread made are given IN
the original publication.
The millers OF the lntermountain
west still insist that the harvester has
detrimental influence on the value
Of the wheat. This claim may be justi
ned when the wheat IN stored In
larger quantities MS was done with the
wheat cut with the header or binder
and stacked, II is quite probable that
wheat cut with the harvester must re
ceive different storage treatment II
may be that wheat cut with the har,
yester and stored In lots OF 10000
bushels will not produce good -four
but this cannot be charged against
he harvester, but Is a special stor
age proposition which merits investi
