parently due to the use of dissolved bone-black were 2.1 

 bushels of grain and 193.4 pounds of straw; those appar- 

 ently due to the muriate of potash were 1 bushel of grain 

 and 1 7.") pounds of straw. 



Manure at the rate of 5 cords per acre gave about 806 

 pounds more straw, I >u ( only .7 bushels more grain than 

 the complete fertilizer, costing some $!."> per acre less: 

 and the manure crop did not indeed surpass the crop on 

 nil rale of soda, alone in much greater degree. The latter 

 application cost $3.20 per acre, while the manure can 

 scarcely l>c estimated at less than $2;"). 



This Montague experiment is one of the most perfectly 

 satisfactory in a long series of such experiments; and it is 

 a pleasure to see that its teaching as to the value of nitrate 

 of soda for the oat crop is so entirely in agreement with 

 that of other experiments with this crop. 



For convenience is appended a statement giving the ar- 

 rangement of plots and the system of manuring in nearly all 

 our soil test work, which now extends over ten seasons: —
