This book covers the two great branches of grass knowl- 

 edge as it relates to teaching in the college the economic 

 value of grasses, and the identification of the main economic 

 species and groups. 



The general economic part comprises a discussion of the 

 value and uses of grasses as compared with other farm crops; 

 the classification of grasses on the basis of their economic 

 uses ; a discussion of their place in the forage crops of the 

 country, mentioning the pasture grasses, native grasses, the 

 kinds adapted to ranges, the discussion of over-grazing and 

 the rejuvenating of worn-out ranges; the grasses of culti- 

 vated pastures ; the grasses and similar plants of meadows; 

 the grass-like plants used for hay and for green feed; grasses 

 for lawns and instructions for the making of lawns ; the use 

 of grasses for ornament and for such purposes as binding of 

 soils, the holding of sand dunes, the fixing of beaches and em- 

 ployment in the textile industries ; a discussion of weeds ; a 

 consideration of the main grass-crop areas of the continent. 



The part devoted to systematic agrostology, or the part 

 that gives a description of the different kinds, goes carefully 

 into the morphology of leaf and flower and stem, provides a 

 discussion of ecology and accounts of all the different genera 

 that are economically important, and ends with a general 

 discussion of nomenclature as applied to grasses.
