periods being 89, 43, and 132 days, respectively. The shortest was 

 118 days and the longest was 147 days. The stands have been 

 slightly poorer than those of No. 314 on the average. The tillering 

 has been more abundant, however, since in three years the propor- 

 tion of suckers has exceeded one sucker to each main stalk. The 

 average acre yield in the 8-year period has been 16 bushels, or about 

 3 bushels better than that of No. 314. Its yield in 1915 was 66 bush- 

 els, one of the best made by any kafir variety.
