VI PREFACE 



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.
