are yet largely experimental, and in use mainly on 
small farms; their adoption, however, would result 
both in increasing the yield and quality of forage 
from a given area, and, if judiciously carried out, 
result in a better preparation of the land for grain 
crops. 
No attempt has been made to discuss all crops 
that may be used for forage, although those which 
have been found of service under special condi- 
tions have been included, as, for example, the 
millets, kafirs and a few of the less well-known 
grasses. The data in reference to these, however, 
have been drawn largely from the experience of 
others. Special attention has been given to the 
legumes, as their use is of the utmost value in 
any system of forage cropping, and many of those 
recently introduced.possess such habits as to per- 
mit their use without interfering with regular grain- 
crop rotations.
