CHEMICAL MANURES. 99 



The second field had also received the same fertilizer in the sprin 

 of 1866, except the quantity of sulphate of ammonia, which h 

 been reduced to 355 pounds, or 71 pounds of azote. 



The return from this field in beets was 42,066 pounds of roots. 



Lastly, the third field in the' autumn of 1866 received 



266 pounds of acid phosphate of lime. 



266 pounds of sulphate of ammonia, or 



56 pounds of azote. 



177 pounds of sulphate of lime. 



M. George Ville, consulted by me as to the easiest method of 

 obtaining a maximum return, advised, in case it should be necessary, 

 the addition of a certain quantity of the incomplete fertilizer over 

 the first two acres. After a hesitation provoked by the magnificent 

 appearance of the plants at the end of the winter, I decided to leave 

 the earth to its own forces, fearing the effects of a too luxuriant and 

 herbaceous growth. I was happy in following this inspiration, for it 

 is very probable the abundant rains of spring had determined the 

 fall of the stalks and defeated my hopes if I had used more 6T the 

 fertilizer.
