bushels. The next lowest yield was 16.9 bushels, m 1910, a very dry 

 year. In 1915, the most favorable season of all, however, its yield 

 was only 46.6 bushels per acre, which was 15 to 20 bushels lower than 

 those of some of the best varieties in other grain-sorghum groups.

Two other races of Manchu kaoliang almost identical with C. I. No. 

 171 are C. I. Nos. 261 and 328. Of these. No. 261 has been grown 

 throughout the whole nine years. It is usually from three to five 

 days earlier than No. 171, but seldom germinates to as good a stand 

 and does not yield as well. The 9-year average acre yield of C. I. 

 No. 261 is only 13.5 bushels, while that of C. I. No. 171 is 21.2 

 bushels, or 7.7 bushels more. C. I. No. 328 was first grown in 1910. 

 It is of about the same earlmess as No. 261 and usually had about 

 the same stand or a little poorer than that of No. 171. Its average 

 acre yield in the 7-year period was 12.9 bushels and that of No. 261 

 was 12.7 bushels, while that of No. 171 was 19.8 bushels. In the 

 same seven years Shantung, No. 293, a very dwarf but stocky 

 and later variety, produced 13.2 bushels. It is evident that while 

 earlier in maturing, neither No. 261 nor No. 328 can compete with 

 No. 171 in yield. No. 261 yielded 12.5 bushels less than No. 171 

 in 1908, a good year, and 17.6 less in 1915, a year of bumper yields, 

 in which No. 328 yielded 21.8 bushels less than No. 171. 



Another selection, C. I. No. 324, which is two to three weeks later 

 than C. I. No. 171, has been growoi during the last seven years. It 

 was thought to be promising, but its average acre yield in that
