Weight o^f air dry material of rye and hairy vetch ; also 

 weight of crimson clover. 



The nearly mature rye on plot 2 yielded only a little 

 greater weight of tops than did inoculated vetch. The roots 

 of rye were much heavier than those of vetch, partly due, it

 finer rye roots. 



Crimson clover, being in a different field, cannot be com- 

 pared in yield with rye and vetch. 



Nitro(;en in Inoculated ani> Nox-Inoculated Plants. 



The thoroughly dried tops and roots from sample areas 

 of one sqaare yard each were analyzed by Dr. J. T. Anderson, 

 associate chemist of this station. 



His results, — which are averages of several determina- 

 tions in each case, — and the figures derived from them, are 

 given in the following table :
