EXPERIMENTS WITH MANURE. 49 



The fourtli and last season I divided the acre into two 

 equal parts, with no noticeable difference in the quality or 

 location of the land. After ploughing, I spread upon one 

 half, which I will designate as lot No. 1, seven hundred and 

 four pounds of Darling's Animal Fertilizer, bought of Whit- 

 temore Brothers, costing, with freight, 815.08, and forty 

 pounds of muriate of potash, costing 81.40, both amounting to 

 816.48. On the other half, lot No. 2, I spread three bags of 

 Stockbridge's Corn Fertilizer, which, according to his for- 

 mula, was expected to produce at the rate of sixty bushels 

 per acre above the natural product of the land, costing, with 

 freight, 817.25. 



The corn was planted with Ross & Co.'s corn-planter, and 

 cultivated wholly with his cultivators, without any hand- 

 labor, except pulling out a few scattering weeds that the 

 cultivator failed to cover sufficiently. Tliis system left the 

 crop clean of weeds, and reduced the cost of cultivation very 

 materially ; which cost of cultivation, and harvesting in the 

 barn, I make 819.50 for the whole acre. The product of lot 

 No. 1 of sound ears of corn was twenty-five hundred and 

 ninety-seven pounds, of which it took seventy-four pounds 

 to make fifty-six pounds of shelled corn, making thirty-five 

 bushels and one-tenth of shelled corn. The three thousand 

 and seventy pounds of stover at 88 per ton would be worth 

 812.28, which being deducted from the cost of production 

 — fertilizers, 816.48 + half of cultivation, 89.75 = 826.23 — 

 would give the cost of thirty-five bushels and a tenth of corn 

 813.95, which is thirty-nine cents per bushel. The product 

 of lot No. 2 was two thousand and eighty-five pounds of ears, 

 equal to twenty-eight bushels and a tenth of shelled corn, and 

 twenty-three hundred and sixty pounds of stover, valued at 

 89.44, which deducted from cost of production — fertilizer, 

 817.25 -f cultivation, 89.75 = 827.00 — leaves 817.56 cost of 

 twenty-eight bushels and a ninth, or sixty-two cents and 

 a half per bushel ; thus showing, that, all other things being 

 equal in tliis experiment, it cost thirty-nine cents to grow 

 one bushel of fifty-six pounds of shelled corn with Darling's 

 Animal Fertilizer, and sixty-two cents and a half with Stock- 

 bridge's Fertilizer. 



In connection with the foregoing I also submit the foUow-
