bushels. The next lowest yield was 16.9 bushels, in 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.

a Average of three plats. 
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 earliness 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 grown during the last seven years. It 
was thought to be promising, but its average acre yield in that
