56 FORAGE CROPS. 



by frost before October. White Milo maize did not 

 mature any seed, and teosinte did not reach even 

 the earing stage. Several varieties of corn planted 

 at the same time matured seed by September i st and 

 some even earlier; and Early Amber sorghum 

 planted at the same date fully matured its seed. 



It is not easy to draw the line between the non- 

 saccharine sorghums and some varieties of millet. 

 The chief differences would seem to lie in the size of 

 the stalk, the abundance or otherwise of the leaves, ^ 

 the size and shape of the head, and the size of the 

 seed. The stems of millets are smaller and more 

 leafy, though Pearl millet has stems nearly as large 

 as some of the sorghums. The heads of the sorghums 

 are larger and broader and less slender in character. 



Distribution. The non-saccharine sorghums 

 are of course specially adapted to conditions warmer 

 and drier than are suitable for growing Indian corn 

 at its best. They have been found preferable to the 

 saccharine sorghums in many localities, for the rea- 

 son that they give better yields of stalk and grain, 

 and some of them are more leafy. It would not be 

 easy or possible at the present time to state exactly 

 where the dividing line should run between those 

 portions of the United States which will grow corn 

 or the non-saccharine sorghums to the best advan- 

 tage. Bearing in mind that the latter require more 

 heat and can endure more drouth, they must be 

 grown south rather than north. The non-saccharine 

 sorghums will probably grow more food per acre 

 than corn south of a line as now described : This 

 line would begin at the Atlantic and would probably 

 run along or near the southern border of the states of 

 Virginia and Kentucky until reaching the Mississippi
