year on the unmanured portion, and yielded 2.46 bushels of 

 unmerchantable corn and 3.77 bushels merchantable, or twen- 

 ty-one bushels per acre. During these four years of harvest, 

 1875 to 1878 inclusive, we have removed per acre two hun- 

 dred and forty-three bushels of corn and sixteen tons of stover j 

 and have applied per acre, in round numbers, the Stockbridge 

 formula for two hundred and eighty bushels of corn and its 

 corresponding amount of stover. We hence have applied 

 the elements nitrogen, phosphoric acid, and potash, and re- 

 moved in crop approximately as below : 



Nitrogen. Phosphoric Acid. Potash. 



Have applied 359 lbs. 1 74 lbs. 432 lbs.

ARTIFICIAL FERTILIZERS IN ENGLAND. 



To farmers in this country, whose success is* getting to de- 

 pend so largely upon the right use of artificial manures, the 

 results of the experience of their English brethren, who are 

 o-oino- over the same around in advance of them, cannot fail 

 to be of interest. From the article, by Dr. Voelcker, on the 

 Influence of Chemical Discovery on the Progress of English 

 Agriculture, previously referred to, w r e quote the following: 



"The manufacture of artificial manures, more especially 

 that of superphosphate of lime, is carried out in England at 

 present on a very large scale, millions of pounds sterling 

 having been embarked in this recent branch of applied man- 

 ufacturing chemistry. There are in England at present 

 probably a dozen or more manufacturers of artificial ma- 

 nures, each of whom produces annually from 45,000 to 50,000 

 tons and upwards of artificial manures, and many more mak-
