 unchanged, except for the barnyard manure plot which had outstripped 

 the " complete fertilizer."

These on the whole make evident the substantial accuracy of the 

 estimates of relative standing above recorded. 



ANALYSIS OF BARN-YARD MANURE USED. 



Moisture at 100° C, 73.470 per cent. 



Oi-ganic and volatile matter, 96.671 " 



Ash, 3.329 " 



Phosphoric acid, 0.247 " 



Magnesium oxide, 0.124 " 



Calcium oxide, 0.322 " 



Potassium oxide, 0.484 " 



Nitrogen, 0.471 " 



Insoluble matter, 2.285 " 



This manure is very near the average composition of all those used 

 in our experiments, the element nitrogen only standing higher among 

 the important ingredients, and phosphoric acid and potash a little 

 lower.
