inclusive. These experiments were conducted cooperatively by the 
State College of Agriculture of the University of Georgia and the 
Office of Cereal Investigations. The results are shown in Table 4. 
Serbia winter spelt at this station yielded considerably more than 
either variety of emmer, and the average yield was only slightly less 
than that of Appier oats. Tennessee Winter barley was the most 
productive crop at Athens, yielding an average of 2,188 pounds per 
acre. This was almost double the yield of spelt and nearly three 
times the yield of Black Winter emmer.

RESULTS AT ARLINGTON EXPERIMENT FARM, ROSSLYN, VA. 
Several varieties of both winter emmer and spelt have been grown 
since 1910 at Arlington Experiment Farm, near Rosslyn, Va., 
opposite Washington, D. C. These experiments are conducted inde- 
pendently by the Office of Cereal Investigations. The, results have 
been published in part by Stanton (55). The yields obtained during 
the past 12 years are shown in Table 5. 
The average acre yield of Black Winter emmer is only 641 pounds, 
indicating that it is not adapted to the conditions at Arlington. 
The yields of spelt, however, are very satisfactory. Alstroum spelt 
yielded an average of 2,180 pounds per acre, while a selection from 
this variety yielded slightly more. During the same period Tennessee 
Winter barley averaged 1,434 pounds and Winter Turf oats 1,586 
pounds per acre. Partial winterkilling of emmer, barley, and oats 
sometimes occurs, while spelt is not injured. The greater hardiness 
of winter spelt is partly responsible for the higher yields. It is also 
better adapted to the general climatic conditions of this section than 
emmer. The difference in adaptation is comparable to that existing 
between the soft red winter wheats and the hard red winter wheats 
(Crimean group), the latter not being adapted to this section. 
Spring grains produce comparatively low yields at Arlington, so 
winter spelt is the most productive of the small grains used tor feed. 
This crop should be more extensively grown in those portions of 
Maryland and Virginia having conditions similar to those at Wash- 
ington, D. C.
