been right, the failures that have been reported may 
invariably be traced to the use of seed which had not 
been acclimated. The American Indians grow corn 
which is excellent for dry-farm purposes; many of 
the western farmers have likewise produced strains 
that use the minimum of moisture, and, moreover, 
corn brought from humid sections adapts itself to 
arid conditions in a very few years. Escobar reports 
a native corn grown in Mexico with low stalks and 
small ears that well endures desert conditions. In 
extremely dry years corn does not always produce a 
profitable crop of seed, but the crop as a whole, for | 
forage purposes, seldom fails to pay expenses and 
leave a margin for profit. In wetter years there is a 
corresponding increase of the corn crop. The dry- 
farming territory does not yet realize the value of 
corn as a dry-farm crop. The known facts concern- 
ing corn make it safe to predict, however, that its dry 
farm acreage will increase rapidly, and that in time 
Sorghums 
Among dry-farm crops not popularly known are 
the sorghums, which promise to become excellent 
yielders under arid conditions. The sorghums are 
supposed to have come from the tropical sections 
of the globe, but they are now scattered over the 
earth in all climes. The sorghums have been known
