THE NON-SACCHARINE SORGHUMS. 63 



where these crops can be successfully grown, the 

 conditions are too dry to admit of the successful 

 growth of the grasses that are ordinarily cultivated. 

 In such locations some winter crop could be made 

 to follow these crops, since the ground is in excellent 

 condition to receive it, and this could be done 

 with but little additional preparation of the land by 

 way of tillage. These crops include winter rye, the 

 winter vetch, the sand vetch, crimson clover, and in 

 some localities, alfalfa. 



Preparing the Soil. The preparation of the 

 land for these crops is much the same as for corn. 

 The aim should be to secure a free, firm and moist 

 seed bed in sections low in the amount of the rainfall. 

 This can best be secured by plowing the land as long 

 as possible previous to the planting of the seed, and 

 by harrowing the surface of the land thus plowed at 

 intervals of more or less duration. This method of 

 managing land will also be very helpful in removing 

 weeds from the uppermost section of the soil. These 

 crops are planted later than corn and even later than 

 sorghum, hence the season is more prolonged during 

 which such treatment can be given to the land. 

 Sometimes in areas much deficient in moisture the 

 plan termed "listing" is adopted in growing some 

 of these crops, as in growing corn. When this 

 method of planting is followed, the soil is not first 

 plowed. Furrows are turned both ways from the 

 line where the seed is to be planted. The work is 

 done by using a double-mold-board plow, which 

 also loosens the soil for some distance below the line 

 of the furrow. In the soil thus loosened the 

 seed is planted. The object sought is to enable
