MANURES. 145 



as such fifty years or more, and, consequently, no part of it had 

 been affected by any application of manure before the present 

 season. It contained thirty-four rods, and was divided into nine 

 lots ; five containing four rods each for the County and State 

 experiment, three of four rods each for trial of super-phosphate 

 by the side of manure, and one of two rods with house ashes. 



The land was of a light, loamy soil, with a gravelly sub-soil. 

 It was ploughed between seven and eight inches deep. The 

 result was as follows : No. 1 had 116 pounds of corn on the 

 cob, and 118 pounds of fodder, which was at the rate of 59.48 

 bushels of shelled corn, and 4,720 pounds of fodder per acre. 

 No. 2 had 128 pounds of corn on the cob, and 103 pounds of 

 fodder, which was at the rate 65.64 bushels of shelled corn, 

 and 4,120 pounds of fodder per acre. No.*3 had 118 pounds 

 of corn on the cob, and 79 pounds of fodder, which was at the 

 rate of 60.51 bushels of shelled corn, and 3,160 pounds of 

 fodder per acre. No. 4 had 56 pounds of corn on the cob, 

 and 42 pounds of fodder, which was at the rate of 28.71 

 bushels of shelled corn, and 1,680 pounds of fodder per 

 acre. No. 5 had 23 pounds of corn on the cob, and 25 

 pounds of fodder, which was at the rate of 11.64 bushels of 

 shelled corn and 1,000 pounds of fodder per acre. The quan- 

 tity of manure used was an even horse-cart body full for each 

 lot, or twenty feet, equal to six and one-fourth cords per acre. 

 It was horse and pig manure, in which leaves had been freely 

 used for litter. It was made the previous winter, and had been 

 carted to the field a few weeks before using. 



The average of the four lots on which manure was used was 

 53.73 bushels of shelled corn, and 3,420 pounds of fodder per 

 acre, or 42.09 bushels of corn, and 2,420 pounds of fodder per 

 acre more than on that where no manure was used. 

 Taking then No. 5, on which no manure was used, as 

 the standard of what the ground would produce 

 without manure, we have a clear gain of 42.09 

 bushels of corn, which at $1 per bushel is . . $42 09 

 And 2,420 pounds of fodder, which at 88 per ton is . 9 68 



$51 77 

 From which, if we deduct the value of six and one- 

 fourth cords of manure, at 87 per cord, . . . $43 75 



Leaves as profit which the manure brought over its cost, $8 02
