The leading varieties of durum wheat at Archer belong to the. 
Kubanka group. This group of durums has broad heads with long, 
pale awns, yellowish, glabrous glumes, and large, hard, amber ker- 
nels. The Beloturka, Kubanka, and Pererodka varieties have given 
the highest average yields. 
The spring common wheats grown at Archer are divided into four 
groups. The Preston group has bearded heads, white glabrous 
glumes, and hard red kernels. The Fife group has beardless heads, 
white glabrous glumes, and hard red kernels. The bluestem group 
has beardless heads, white pubescent glumes, and hard red kernels. 
The unclassified group includes some varieties which do not belong 
in any of the three groups just described. The Galgalos variety has 
a beardless head, brown pubescent glumes, and large soft white ker- 
nels. The Defiance has a beardless head, white glabrous glumes, and 
soft white kernels. The leading varieties in each of these groups are 
shown in Table XI. 
RATE-OF-SEEDING EXPERIMENT. 
A rate-of-seeding experiment with Arnautka durum wheat has 
been conducted at the Cheyenne Experiment Farm for three years, 
1913 to 1915, inclusive. The annual and average yields obtained 
are shown in Table XIII. 
In 1913 the rate-of-seeding test was sown in tenth-acre plats on 
breaking. Good stands were obtained from all rates. The highest 
yield was obtained from the 2-peck rate. 
In 1914 the rate-of-seeding test was sown in tenth-acre plats on 
fallow land that had been spring plowed. Good stands were ob- 
tained. The highest yield was produced on the plat sown at the 
rate of 4 pecks per acre. 
In 1915 the rate-of-seeding test was sown in duplicate twentieth- 
acre plats on double-disked.corn ground. The highest yield was ob-
