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

 bushels of grain and 193.4 ])ounds of straw; those appar- 

 ently due to the muriate of i)otash were 1 bushel of grain 

 and 175 pounds of straw. 



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

 ])ounds more straw, but only .7 bushels more grain than 

 the complete fertilizer, costing some $13 per acre less; 

 and the manure crop did not indeed surpass the crop on 

 nitrate of soda alone in much greater degree. The latter 

 application cost $3.20 per acre, while the manure can 

 scarcely be estimated at less than $25. 



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 : —
