COMPARATIVE YIELDS OF THE KAFIR GROUP. 
The annual and average acre yields of the leading races in each 
variety of the kafir group are given in Table XXX. The average 
yields are given for the 7-year, the 8-year, and the full 9-year periods. 
The table contains yields of 17 lots, of which 5 are Blackhull, 1 
Sunrise, 1 Dawn (dwarf), 1 White, 2 Red, and 7 new kafirs. Seven 
of the lots have been grown throughout the 9-year period. 
In the seven years from 1910 to 1916, inclusive, the Dawn, the Sun- 
rise, and C. I. No. 316, one of the new varieties, lead with average acre 
yields between 17.5 and 17.9 bushels, that of the Dawn variety being 
highest. A Red kafir (C. I. No. 356) stands next with an average 
acre yield of 16.5 bushels, and Blackhull (C. I. No. 71) ranks fifth 
with an average yield of 15.7 bushels per acre. In the 8-year period 
the same three varieties lead, and Blackhull (C. I. No. 71) again 
holds fifth place. Fourth place is taken by Blackhull (C. I. No. 
335), the Red (C. I. No. 356) having been grown only seven years. 
In the 9-year period, Dawn kafir still leads with an average acre 
yield of 18.8 bushels. Sunrise has been grown only eight years and 
Blackhull (C. I. No. 71) advances to second place with an average 
yield of 17.3 bushels. Third and fourth places are occupied by 
Blackhull selections, with average acre yields of 16.9 and 16.5 bushels,
