ing Qualities of Different
Wheats.

Z chemistry department OF the
4 agricultural experiment station
SCI .ompleted all the work of its five
~ study of the chemical COM
,,,on and m illing quality of Wash
ton wheat. A report of this work
hoen prepared as bulletin of
- station and will soon be ready for
4 Aribution'
rho first samples collected were of
j crop of 1906 and the last of the
~ Of 1909. In all, 431 samples
~ been tested. These included
~ samples of bluestem, 65 of little
I'M IS of Turkey red, 43 of Jones
Inter fife, q of fortyfold, II of red
Alien, rs of Red Russian, 13 of
,.rarOpi, each of white amber and
4 .onors and SO samples of 20 other
udeties. The samples came from
asy part of the state where wheat
81 crown for milling purposes.
W hHdly 20 ESiClI Sample
"a Wheat from each sample was ana
ned. A weighed quantity of it was
hen ground into flour in a small ex-
81 Rrimental roller mill, and the yield
Il -four, bran and shorts determined.
finally the -four was tested for
duten and the food or feeding value
81 the -four, bran and shorts deter
mined by analysis. Numerous bak-
hg tests of the flour were made and
the size and quality of the loaf of
bread which could be produced from
the -four under standard conditions
was determ ined.
The averages of all the results of
these tests show that Washington
Fheats, as rule, contain less pro-
tein, the constituent which yields the
gluten in -four, than do the average
hard winter wheats of Kansas, or the
hard spring wheats of the Dakotas,
but that they are similar in compost
ton to the Wheats of Iowa, Illionis,
Indiana, and the other central Miss
issppi Valley states.
Eight Leading Varieties
The eight leading varieties grown
In this state showed the following
average protein content for the five
years: Bluestem, 1914 per cent;
little club, 1915 per cent; Turkey
red 11.27 per cent; fortyfold, 1914
per cent; Red Allen, 1904 per cent;
Red Russian, 9:76 per cent; white
amber, ILL per cent The average
gluten test of the -four from these
same samples was: Bluestem, $3.50
per cent; little club, 1855 per cent;
Turkey red, 31.01 per cent; Jones
winter fife, 29.15 per cent; forty
fold, $3.50 per cent; Red Allen,
S3.45 per cent; Red Russian, 1886
per cent; white amber, 29.15 per
cent.
These results show that of the
varieties now commonly grown in
this state bluestem and hed Allen
stand in class by themselves as SUI
perior to all others. Turkey Red
and Jones' fife come next, the Turkey
wheat being slightly better than the
fife.
Turkey Red Deteriorates
Turkey Red, when first introduced
IN any part of the wheat belt, shows
quality nearly equal to bluestem, but
deterlorates after it has been grown
LOT a number of years under the
climatic conditions. Little club,
white amber, and fortyfold form a
thlrd class of lower milling and food
value, their relative rank being in
the order named. Red Russian is
lowest of any of the com mon varie-
ties IN its protein and gluten test.
The average composition Of all the
samples Of all varieties grown in the
inherent districts of the wheat belt
was found as follows:
