respectively. Blackhull and Red selections tie for fifth place with 
average yields of 13.9 bushels. 
The breeding of the early variety, Sunrise, and tte early and dwarf 
variety, Dawn, is seen to be justified by the outstanding favorable 
results.

THe Kaoiiane GRovpP. 
The kaoliangs are graim-producing varieties of sorghum from 
China and Manchuria. The most important varieties have been 
separated by a simple key (p. 17). The group has been quite fully 
described by the senior writer‘* in a previous publication. 
The kaoliangs are very diverse in height, earliness, and produc- 
tiveness. So oo only one variety, the Euineia: has become com- 
mercially important in the United States. All have dry pithy stems, 
and many of them are fairly early, presumably with rather low water 
réquirements. However, those which are early enough to be valu- 
able have never been able to compete in yield with Dwarf milo, 
milo, Sunrise kafir, etc., except at the extreme northern edge of the 
sorghum belt, asin South Dakota. The varieties grown are present- 
ed in three subgroups, White, Blackhull, and Brown, im Tables 
XXXI to XXXVI, inclusive.
