BULLETIN 618, r. S. DEPARTMENT OF AGRICULTURE. 
Of the common wheats, Kharkof, of the Crimean group, outyieLded 
even Pehssier in the 7-year period by 5 bushels, or 16 per cent. The 
leading spring common wheats are outyieLded by the durums in 
quantities that are significant. Fife and Preston outyield Bluestem. 
Marquis, however, which was not included in the experiments until 
1913. has an average yield of 33.1 bushels during the four years, 
compared with 2S.S bushels from Ry sting Fife, 30.8 bushels from 
Kubanka, and 32.3 bushels from Pehssier. In these four years, 
therefore, it has outyielded not only the Fife wheat, but the two best 
durums as well. The durums, especially Pehssier, unquestionably 
are good wheats for this section. Marquis is as good and the hard 
red winter wheats are better than either. 
Here, as at Akron, Colo.. Pehssier has proved the best adapted of 
all durum wheats tested. These experiments, together with those 
at Archer, Wyo., and the result of a single year at Havre, Mont., 
indicate that Pehssier is the best-yielding durum wheat yet obtained 
for the drier western plains area having an altitude of 4.000 feet or 
more. 
RESULTS AT BRANDON". MANITOBA. 
The Brandon Experiment Farm is located on a sandy loam soil. 
Its altitude is 1.176 feet, and its average annual rainfall is 13 inches, 
according to a 9-year record. The station is maintained by the 
Canadian Department of Agriculture, and the data presented hi 
Table . XX V have been taken from the published annual reports 
(Canada Experimental Farms. 1896-1908).

A variety of durum, wheat was included in the experiments from 
1895 to 1905. It was grown under the name Goose, but is probably 
the Arnautka variety. Two other varieties were included in the last
