i Yields of Arnautka C. I. No. 1493 are shown for 1903 to 1910; C. I. No. 1547 for 1911 to 1913; C. I. No. 4072 
for 1914; C. I. No. 4064 for 1915 and 1916. 
The record of the yields is favorable to the durum wheats in com- 
parison with spring common wheat. The best of the latter in a 12- 
year average has been Preston, but its yield of 13.5 bushels is 1.4 
bushels below that of Arnautka and 2.7 bushels below that of Ku- 
banka. Power and Haynes fall 2 and 2.3 bushels, respectively, below 
Preston.
