3. Sherrod's Kansas Dent corn 
The hybrid is evidently much less productive than the original 
Kansas Dent corn (Sherrod's) while the water requirement is 
practically the same. A striking observation concerning the 
hybrid was that the vegetative parts were much less pubescent 
than with either of the three varieties entering into the cross. 
It is evident that if Chinese corn is especially drouth resistant 
it is so by virtue of other reasons than low water requirement. 
SORGHUMS. 
Milo and Black Amber sorghum were compared with our 
standard variety of Hogue's Yellow Dent corn. 
Milo is a nonsaccharine grain sorghum, grown extensively in 
some regions for grain, while Black Amber is a saccharine sorghum 
grown primarily for forage. Both are recognized as unusually 
drouth-resistant crops as compared with corn, and the object 
of this experiment was to determine whether such drouth resist- 
ance may be due to a lower water requirement. The results 
follow:

Compared with the average for 11 corn varieties, the milo 
and corn had practically the same water requirement per unit of 
dry matter, while sorghum exceeded the corn 16 per cent. 
The milo used 5 per cent less water per unit dry matter than 
Hogue's Yellow Dent corn, while Black Amber sorghum used 
13 per cent more. 
These data suggest that other causes of drouth resistance in 
sorghums must be looked for than a relatively low water require- 
ment. One cause doubtless is their ability to tide over a period
