corn or sorghum, millet, rape, field roots and cab- 

 bage. And the more important of these would in- 

 clude peas and oats or peas and vetches, millet and 

 rape. In the latter the order would be: Winter 

 rye, medium red clover, mammoth, or alsike clover, 

 peas and oats, or peas and vetches, corn, sorghum, 

 millet, rape, field roots and cabbage. In the central 

 third of the section the most favored varieties would 

 include, peas and oats, corn or sorghum, millet and 

 rape. In the southern third of the same these 

 would include medium red clover, the soy bean, or 

 cowpea and corn, or sorghum. Where crimson 

 clover and alfalfa could be grown, these would be 

 ready for being fed immediately after winter rye. 



Succession in Section No. 3. Winter rye, win- 

 ter oats, crimson clover, the common winter vetch, 

 the sand vetch, corn, sorghum, the cowpea, the soy 

 bean, rape and cabbage can be grown with more or 

 less success in nearly all sections of the several states 

 comprised in this section. The non-saccharine sor- 

 ghums and millet in some of its forms can also be 

 grown at their best in certain sections, but not so 

 generally as nearly all of the various plants previ- 

 ously named. Alfalfa grows admirably in many 

 localities, but does not succeed in others, and the 

 same is true of field roots, and in many sections 

 Japan clover, the velvet bean and teosinte grow with 

 much vigor. More especially is this true of areas 

 that lie within the Gulf states. 



For the northern half of Section No. 3 the 

 succession would be: Winter rye, winter oats, 

 crimson clover, the common winter vetch, the sand 

 vetch, corn, sorghum, one or more of the non-
