EXPERIMENTS WITH MARQUIS WHEAT. 
23 
RESULTS AT LANGDON, N. DAK. 
At Langdon, as at Edgeley, the experiments are conducted inde- 
pendently by the North Dakota Agricultural Experiment Station, 
and the results are used here by courtesy of the director and his 
associates. The experiments have included the Marquis during only 
two years, 1914 and 1915. The annual and average results are shown 
in Table XVI and the yield of the leading variety of each group in 
figure 6. 
The results may be seen at a glance. The two durum varieties far 
excel the Marquis and Glyndon. In the Fife group the Marquis out- 
yields the Glyndon by 6 bushels, or more than 27 per cent. The 
yields of Bluestem varieties under the same conditions are not 
reported.

RESULTS AT WILLISTON, N. DAK. 
The varietal experiments at Williston have included Marquis 
wheat during three years, 1913 to 1915, inclusive. The annual and 
average yields are shown in Table XVII. and the average yield of the 
leading variety in each group is shown graphically in figure 6. 
At Williston, as elsewhere, the durum varieties excel any spring 
common wheats in yield. The best durum exceeds that of the 
Power, the best spring common, by 4.6 bushels, or nearly 14 per cent. 
Considering only the common wheats, the rank of the groups is Fife, 
Bluestem ? Preston, and Crimean (winter), in the order named. 
Among the Fife varieties, the Power outyields the Marquis by 1 
bushel, or 2.5 per cent. The Glyndon, in the Fife group, and the 
Dakota, a Bluestem variety, almost exactly equal the Marquis in 
yield. The yields of the winter-wheat varieties are very low. 
The comparatively low yield of the Marquis in 1915 was due to 
damage by a late spring frost. The plants were about 8 inches tall 
at the time. Not only at Williston but also at other points in the 
State the Marquis seemed to be more seriously injured than other 
varieties.
