ANALYSIS OF MANURE USED. 



Moisture at 100° C, 



Organic and volatile matter, 



Ash, 



Phosphoric acid. 



Calcium oxide, 



Magnesium oxide. 



Potassium oxide, 



Nitrogen, 



Insoluble matter. 

 This manure on the whole stands first among all those used. It 

 contains the highest percentages of both potash and nitrogen while 

 phosphoric acid is about the average. It does not, however, cause 

 an increase in proportion to its quality. This is almost exactly the 

 average, viz. : 22.1 bushels of hard corn.
