vi PREFACE. 



land for the seed and sowing the same, pasturing and 

 harvesting for hay and for seed and renewing the grass- 

 es where this may be practicable. It will also discuss 

 the questions of temporary, permanent and range pas- 

 tures respectively and that of meadows and making hay. 

 Although the clovers are largely grown for practically 

 the same economic uses as grasses, the discussion of the 

 former will be reserved for a separate volume. 



In writing the book, the aim has been to prepare a 

 volume that would discriminate between the important 

 and the unimportant in economic grasses, and to present 

 information in an orderly and consecutive way with 

 reference to the former onlyj that would in some meas- 

 ure at least meet the needs of the farmer and the stu- 

 dent of agriculture.
