These results are in no wise unusual; in our five years' 

 work on the Station Farm, some of the results of which were 

 reported in Bulletin No. 6, it has been found that the six com- 

 binations of chemicals which have given the highest income, on 

 corn, per dollar invested have averaged : 



Phosphoric acid 6.4 



Potash 15.5 



Nitrogen 2.5 



EXPERIMENTS WITH ENSILAGE, SWEET CORN AND POTATOES. 



The following are the results of experiments with the same 

 combinations as for corn, on the crops above mentioned.
