Or if we take that which appeared to be the most judicious 

 application of the manure, we find a clear profit of $22.73 per 

 acre. 



The value of the crops on the several lots, by the above 

 estimate, is as follows : — 



On No. 1, where the manure was turned under at the first 

 ploughing, f78.36. On No. 2, on which the manure was 

 ploughed in at the second ploughing, $82.12. On No. 3, 

 where the manure was cultivated in, $73.15. On No. 4, where 

 the manure was spread upon the surface after planting, $35.43, 

 and where there was no manure, $15.64. 



The calculation of the corn was made by taking seventy- 

 eight pounds of corn on the cob as equal to one bushel of 

 shelled corn. * 



In continuation of the experiment, No. 6 had a small handful 

 of Coe's super-phosphate in the hill before planting, which was 

 well mixed with the soil, and also a small quantity spread upon 

 the surface at the first hoeing, and mixed with the soil. No. 7 

 had the same spread upon the surface after planting, and again 

 after the first hoeing. No. 8 had the same spread on the surface 

 after the first, and again after the second hoeing. No. 9 had 

 ashes spread on the surface after the first and second hoeing. 

 The super-phosphate used was 800 pounds per acre, and the 

 ashes, 80 bushels per acre. 



No. 6 had 55 pounds of corn on the cob, and 47 pounds of 

 fodder, which is at the rate of 28.20 bushels of shelled corn and 

 1,880 of fodder per acre. Nos. 7 and 8 were so nearly alike that 

 they were harvested and weighed together. They had each 57-^ 

 pounds of corn, and 46| pounds of fodder, at the rate of 29.84 

 bushels of shelled corn and 1,860 pounds of fodder per acre.
