of the same ground I raised carrots at the rate of nearly 1,000 

 bushels to the acre, last year, when the season was less propi- 

 tious than this. The seed was purchased both years, but from 

 diflierent soiirces. The value of the experiment is not interfered 

 with by this small yield, except in this, that had the carrots grown 

 through the entire season, I am inclined to the belief that that 

 portion manured with the compost would have increased in 

 a greater ratio than the others. The ground was hoed twice, 

 and the crop harvested Oct. 30. Total average cost of produc- 

 tion, including interest on the land and taxes, fifteen cents per 

 bushel.

Statement of B. Safford. 



The piece of land on which I tried my experiments was broken 

 up in the fall of 1853, and in the spring of '54 a part of it wa^ 

 planted with potatoes, with a little guano, plaster and hen ma- 

 nure ; the remainder was sown with oats without any manure. 

 Last spring I spread on a very small coat of green manure and 

 ploughed it in : I then harrowed and furrowed it ready for 

 planting. I commenced planting on the end that was planted 

 with potatoes last year. The kind of corn I planted is the Tus- 

 can, or smutty white.
