 ter XIII considers Eye Grasses and probably inchides 

 all of this family, at present, worthy of cultivatioD 

 under American conditions. In Chapter XIV various 

 grasses are considered of still less economic importance 

 to the whole country. It may even be questioned as to 

 whether some of these are worthy of cultivation, as for 

 instance, velvet grass {Holcus lanatus) but it will be 

 found that each of them has a useful mission in some 

 locality and under some conditions. 



Chapter XV discusses Temporary Pastures ; Chapter 

 XVI, Permanent Pastures; Chapter XVII, Meadows 

 and Making Hay, and Chapter XVIII, Pastures on the 

 Range. The discussion of each of these phases of the 

 grass question is of necessity brief, too brief probably 

 to be sufficiently comprehensive and succinct, but the 

 course adopted seemed necessary to avoid unduly swell- 

 ing the contents of the volume.
