difference. The piece was then sowed to oats and grass seed. 

 In liarvesting, I measured off one rod square of the unmanured 

 ground and a like quantity of the manured, the two being within 

 a few feet of eacli other. The two pieces were reaped, taken 

 home and put into the barn. The result was as follows : — 



The rod dressed with guano yielded 12 quarts of oats, weigh- 

 ing 10 lbs., straw 10^ lbs. This per acre would be — 

 531 bushels, at 50 cents, . . . $26 75 

 1,040 lbs. straw, at $8, . . . . 6 56 



$33 31 



The undressed rod yielded 8 quarts of oats, 5^q lbs., making 

 per acre — 



29 bush., 30 lbs. per bush., 50 cts. per 

 bush., ..... 

 820 lbs. straw, at $8, . . . 



Difference in favor of guano — 



Per acre, ...... 



Deduct cost of 200 lbs. guano, . 



Net profit per acre, ... $9 53 



It will be noticed in this experiment, that the oats not only 

 yielded much more, but were of much better quality, where the 

 guano was used. As far as my observation goes, this manure, 

 when applied to cold land, jjroduces a much more striking effect 

 upon a crop of oats, than upon one of corn.

Statement of Kelita Hubbard. 



TuENiXG IN Green Crops. — I have practised, for several years, 

 turning in rye for manure. My land has nearly doubled in 

 value. I can raise two bushels of potatoes, corn or rye, where 

 I could raise but one a few years ago. I plough my land as 

 soon as convenient after harvest, when my cattle have little to 

 do. The feed in the fall pays for ploughing and seed. I turn 

 in the rye crop in the spring, and think it is equal to five loads 

 of manure to the acre. This operation destroys the weeds, pul- 

 verizes the soil, and saves much labor in the cultivation of the 

 next crop.
