action of all the nitrogen fertilizers, but apparently particu- 

 larly so in the case of the nitrate of soda. Moreover, consid- 

 erable daniao-e was done both to dandelions and strawberries 

 through the burning of the leaves, caused by the application 

 of the nitrate of soda and the sulfate of ammonia. The 

 application of either of these chemicals as a top-dressing to 

 a growing crop requires the utmost care. It was not the 

 belief of the assistant applying the materials that these chem- 

 icals adhered to the leaves when applied in such quantity as 

 to prove injurious ; but the result proved that he was mis- 

 taken in his judgment, for the injury through burning of the 

 leaves both of the dandelions and the strawberries where 

 nitrate of soda and sulfate of ammonia were applied was 

 very serious. Doubtless as a consequence chiefly of the 

 conditions to which attention has been called, the dried 

 blood, as compared with the other nitrogen fertilizers, ranks 

 this year relatively higher than in any previous year. 



The average rate of yield per acre obtained with each of 

 the nitrogen fertilizers, used it Avill be remembered in addi- 

 tion to the manure, for the present season is shown in the 

 following table : —
