METHODS OF LEGUME INOCULATION. 5 



THE DISTRIBUTION OF CULTURES BY THE DEPARTMENT OF 



AGRICULTURE. 



The Bureau of Plant Industry is carrying on field experiments to 

 determine, if possible, what soil conditions are most favorable for the 

 successful inoculation of leguminous crops by the use of pure cultures, 

 and also to determine under what conditions it is useless to attempt 

 to inoculate certain of the legumes without some radical change in 

 the method of fertilizing or cultivating these fields. To extend this 

 experimental work as far as possible, the Department of Agriculture 

 is willing to supply cultures in any reasonable quantity, requiring 

 only the fdling in of blank reports which are occasionally forwarded 

 for this purpose.
