86 BULLETIN 341, U. S. DEPARTMENT OF AGRICULTURE. 
Every farmer who undertakes cxpeimione with soy beans should) 
send to the State experiment station and to the United States De- q | 
partment of Agriculture for the latest literature relating to this — 
crop. : 
ALFALFA. 
Thus far nothing has been said about alfalfa in this region except- 
ing merely to mention the fact that some 75 acres of it were found 
upon the 378 owner farms. Since this survey was completed the 
area of this crop has considerably increased in Chester County. 
Where the cultivation of alfalfa is successful it is a desirable crop — 
for live-stock farms, but the discussion of cropping systems involv- 
ing alfalfa would lead into a field which is to be covered in another 
bulletin dealing with cropping systems for the region of this survey —

and other similar localities. It may be added, however, that on farms — j 
having a considerable acreage of alfalfa the 5-year rotation outlined $ 
in the middle of Table XLIX might be more satisfactory than the | 
G-year rotation. The alfalfa when once established should continue % 
to occupy the same field as long as it is producing a satisfactory crop. _ 
The remainder of the farm could then be continued in the 5-year — 
rotation. 
FARM EXPENSES. 
The data obtained in this survey are not sufficiently extensive to — 
permit a detailed study of the relation between the expenditures for 
different purposes and the efficiency of local farming. If is not 
doubted, however, that such studies would give results of interest 
in connection with the problems of farm management. As records |
