period of seven years from 1908 to 1914, inclusive. Yields of Ku- 
banka durum wheat (C. I. No. 1440) and Haynes Bluestem wheat 
(C. I. No. 2874, Minn. No. 169) for the same years at the same stations 
are given for purposes of comparison. 
It is desirable to compare the performance of Ghirka Spring with 
that of some other Fife wheat, but no one variety of Fife wheat 
other than Ghirka has been grown at all of the seven stations during 
this entire period. However, the Rysting Fife (C. I. No. 3022) has 
been grown at more stations during the period than any other variety 
of this group and is chosen for comparison. Yields of Glyndon Fife 
(C. I. No. 2873) have been substituted at the stations where the 
Rysting was not grown. The two varieties are very similar in 
appearance and are only different strains of Fife wheat. 
The seven stations for which results 1 are presented are Moccasin, 
Mont,; Williston, Dickinson, and Edgeley, N. Dak.; and Brookings 
Highmore, and New- 
ell, S. Dak. The lo- 
cation and elevation 
of these stations are 
shown in figure 2 . At 
all the stations except 
Edgeley, the work was 
conducted coopera- 
tively by the United 
States Department of 
Agriculture and the 
State experiment sta- 
tions. At Edgeley the 
tests were conducted 
entirely by the State, 
and the results given are quoted from the published annual reports 
of that substation for 1908 to 1913, inclusive. The results for 1914, 
not yet published, were kindly furnished by O. A- Thompson, super- 
intendent of the Edgeley substation. 
The annual and average yields of four varieties of wheat, Kuban^a 
durum, Ghirka Spring, Rysting or Glyndon Fife, and Haynes Blue- 
stem, grown at seven northern Great Plains experiment stations for 
the 7-year period from 1908 to 1914, inclusive, 2 are shown in Table I. 
The average yield of each variety for each station and ajso the average 
for all stations are shown graphically in figure 3. 
i These data have been accumulated at the various stations by the following members of the scientific 
staff of the Office of Cereal Investigations: Manley Champlin (Brookings. S. Dak.); Charles H. Clark, 
J. A. Clark, and R. W. Smith (Dickinson, N. Dak.): J. D. Morrison (Highmore, S. Dak.); E. L. Adams and 
N. C. Donaldson (Moccasin, Mont.); Cecil Salmon and J. H. Martin (Newell, S. Dak.); and F. E. Babcock 
OYilliston. N. Dak.). 
2 The manuscript of this bulletin was prepared in the spring of 1915, but publication has been 
unavoidably delayed. This bulletin includes experimental results only to the end of 1914.
