PREFACE 



are much sought after by Southern farmers, and some 

 suggestions are made in the text concerning hay and 

 pasture plants worthy of trial. Methods of fitting 

 grass crops into Southern cropping systems constitute 

 another important problem which the farmer must 

 work out largely for himself. The best we can do for 

 him in this line is to give him the benefit of the expe- 

 rience of the most progressive of his fellows. This 

 the writer has attempted to do. 



On the irrigated lands of the West, farmers are not 

 particularly concerned about grass problems, except 

 where alkali has begun to appear*. But there are im- 

 mense areas in the West at present unutilized, except 

 in the primitive fashion of the herdsman on the open 

 range, on which the problem is to find grasses that 

 will produce a crop under arid or semi-arid conditions. 

 In so far as the solution of this difficulty has been ac- 

 complished, the results are set forth in discussing the 

 individual grasses. Attention is called to investiga- 

 tions now in progress with a view to finding other 

 grasses adapted to these hard conditions.
