INTO the dry farming operation of the
inter-mountafn west has resulted in q
eductfo Of the cost Of operation on
the larger dry farms. The claim was
soon made by the millers of certain
sections OF the state that wheat cut
with the harvester could not be con.
Serted Into flour Of good quality.

Ties OF the -four produced.
The yield Of -four obtained from the
turkey variety cut with the harvester
IN 1910 was 1866 per cent. of the
wheat while the yield of -four OBJ
tanned from the wheat cut with the
binder and stacked was 72.77 Der cent
Ihe yield of -four obtained from he
kofod wheat cut with the harvester in
1910 was 72.17 per cent. while the
yield OF flour produced from the wheat
cut with the binder stacked was 1912
per cent. 1t is thus readily seen that
with respect to the yield of the -four
the method Of harvesting has no In.
nuence whatever. 1t is interesting to
note, however, that a greater per cent
of high grade -four may be obtained
from the Turkey variety of wheat.
About eighty per cen of the -four pro-
duced from the Turkey wheat would
be classed as a high grade -four, while
only about forty per cent. of the -four
produced from the Kofod would be
classed as high grade.
In case of the chemical composition
OF the flour obtained, no conclusion
can be safely drawn regarding the in
fuence of the harvester. In case Of
the Turkey variety of wheat, the -four
produced from the wheat which had
been stacked is slightly higher than
that Of the -four produced from wheat
cut with harvester. In case of the
Kofod variety Of wheat. however. this
Is 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 a 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 are 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 1866 &C. and 1858 &C.

the volume of loaf of the bread made
from the -four produced from the Tur-
key which has been cut with the
binder anc stacked was 1857 &C. In
case of the Kofod variety. these num-
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 it is thus seen that II any in1u-
ence can be ascribed to the harvester
at all it must be a favorable influence.
While the investigation did not
show any influence Of the harvester
on the b~read-making value of the -four
produced. 1t did demonstrate the value
Of Turkey Red wheat for flour produc-
ton. The Turkey Red wheat produces
a uniform four Of high grade which
has the strength to produce a loaf OF
bread of good volume. The -four pro-
duced from new Turkey Red wheat
seemed to make as good bread as
flour produced from old Turkey Red
wheat. while the -four produced from
new Kofod wheat produced a loaf of
bread very much inferior in quality
and yet the year-old kofod wheat
produced q good -four. Actual photo
graphs of the bread made are given In
the original publication.
The millers of the inter-mountafn
west still insist that the harvester has
a detrimental influence on h value
NJ the wheat. This claim may be justt-
fed when the wheat Is stored In
larger quantities as was done with the
wheat cut with the header or binder
and stacked. 1t is quite probable that
wheat cut with the harvester must re
ceive different storage treatment. II
mav be that wheat cut with the har-
yester and stored in lots of 10000
bushels will not produce good flour.
