xiv 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 dificulty 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. 
The chapter on seeds was contributed by Mr. Edgar 
Brown, in charge of the Seed Laboratory of the United 
States Department of Agriculture. 
The chapter on ‘‘Lawns and Lawn-making’’ was 
prepared by Mr. C. R. Ball, of the United States De- 
partment of Agriculture.
