ON EXPERIMENTS ON MANURES. 89 



There was no perceptible difference in the corn. But 

 the potato tops, where the salt was spread, were con- 

 siderably larger. The result of potatoes, however, was 

 as follows : 



Per acre. Salt, 235 bushels. 

 Lime, 292 " 



272, without salt or lime. 

 In an adjoining field, where I ploughed in manure, I 

 put into the hill as follows : 



Pounds. Bushels. 



Saltpetre, 150 to the acre. Corn raised, 64 per acre.

The above corn was weighed, and reckoned 70 

 pounds to the bushel. 



In the fall of 1841, I prepared compost as follows : — 

 with about eight loads of meadow mud I mixed fifteen 

 bushels of wood ashes; also, another heap of the same 

 size, I mixed two casks of lime. After a few weeks I 

 spread it on to the grass in the same field. The grass 

 the present season showed the good effect of the com- 

 post. But that dressed with compost of mud and ashes 

 was the best. 



In the fall of 1839, I prepared a heap of compost as 

 follows : — one part stable manure, and two parts mead- 

 ow mud. In the spring of 1840, I used it in the hill 

 for potatoes. Also, part of the same field I manured 

 with the same quantity of barn manure. There was no 

 perceptible difference in the potatoes. In 1841 it was 

 manured, and planted with corn. In 1842 it was sow- 

 ed with oats. There was no perceptible difference in 

 either of the crops. 



in regard to salt, I have used it in different ways, 

 and never have received any benefit from it, excepting 

 as above stated in potato tops and compost for corn,
