MANURES. 23T 



the acre. The cost of the manure applied to the hand, was 

 fifteen dollars, and of the guano, five dollars, making a differ- 

 ence of ten dollars per acre. As"'near as I can judge, at the 

 present time, there are ten hushels more of corn on the half 

 that was guanoed, than on the other half. There is certainly a 

 much heavier growth of stalks, but as it is not yet husked, I 

 cannot state the exact difference. 



Having a piece of sandy plain, too poor to produce any thing 

 but a light crop of rye once in three or four years, I thought I 

 would raise a crop of corn on it. Accordingly I ploughed in 

 300 lbs. 'of guano on an acre, and fallowed it. I gave it a light 

 harrowing, planted, hoed it twice, at a cost of eleven dollars, 

 besides the ploughing, which I should have done if I had not 

 planted it. I have husked nearly the whole of it, and I think I 

 can safely calculate on twenty-five bushels of good sound corn 

 — making a net profit of $14, or 130 per cent. The profit on 

 this acre would purchase two acres of such land at the present 

 market value. I also harrowed in, a year since, at the rate of 

 100 lbs. of guano to the acre, at the time of sowing rye, and it 

 increased my crop seven bushels. These and other trials have 

 fully satisfied me, that while we can procure guano for three 

 cents a pound, we may be confident, that if properly used, a fair 

 annual investment in it will return a good income, whether 

 applied to warm or cold lands.

Statement of Theodore G. Huntington. 



The piece of ground on which my experiment was made, is a 

 cold, dry loam. In the summer of 1854, it was in grass, and 

 probably did not produce 500 pounds of good hay per acre. In 

 the spring of 1855, it was ploughed, and manured at the rate of 

 twenty loads per acre of composted manure, consisting of muck, 

 ashes, plaster and saltpetre, which cost, on the ground, one dol- 

 lar per load. I planted to Carter potatoes, and obtained a small 

 yield of forty bushels per acre, but of good quality. 



Last spring, the ground, after being ploughed, was dressed 

 with 200 lbs. of guano per acre, a small piece on the poorest 

 part of the lot being left undressed for the purpose of noting the
