of the clover, but left it much the thickest on the oldest marled piece, so as 

 a,!.'ain to show the dividing line, and to yield, in 1823, two middling crops 

 to the scythe -the first that I had known obtained from any acid soil, with- 

 out high improvement from putrescent manures. 



1823. At rest— nothing taken off, except the clover on B C m I. 



1824. In corn— product seemed as before, and its rate maybe inferred 

 from the actual measurements on other parts, which will be stated in the 

 next experiment, the whole twenty-six acres being now cleared, and brought 

 under like cultivation. 



Experiment 2. 



The part e / n 0, cleared and cultivated in corn at the same times as the 

 preceding— but treated differently in some other respects. This had been 

 deprived of nearly all its wood, and the brush burnt, at the time of cutting 

 down- and its first crop of corn (1818) being very inferior, was not fol- 

 lowed by wheat in 1819, because promising to6 little product to pay for the 

 cost of the crop. This gave two years of rest before the crop of 1821 — 

 and five years rest out of six, since the piece had been cut down. As be- 

 fore stated, the soil rather lighter on the side next to e, than nf. 



March, 1821. A measured acre near the middle, covered with six hun- 

 dred bushels of calcareous sand, containing 20 percent, of calcareous earth, 

 the upper layer of another body of fossil shells. 



Results. 1821. In corn. October— the four adjoining quarter acres, 

 marked 1, 2, 3, 4, extending nearly across the piece, two of them within, 

 and two without the marled part, measured as follows : 

 No^marled, No. 1, 6| > ^^erage to the acre 22^ bushels of grain. 



Marled, No. 2,' 8J } ^^ .3^ ^^^^^^^ 



Do. No. 3, 8g- ^ ^ 



The remainder of this piece was marled before sowing wheat in 1821. 



1823. At rest. 



1824. In corn— distance 5i by 3:^ feet, making 243G stalks to the acre. 

 October 1 1th, measured two quarter acres very nearly coinciding with Nos. 

 2 and 3 in the last measurement. The products now were as follows : 



No 2 brought 7 bushels 3q: pecks, ^ 



or per acre, - - - 31.1 > average 31. 2^ 



No 3 brought 8 bushels, - - 32 ) 



Average in 1821, - - - - 33.1 



Experiment 3. 



The part efg h was cut down in January, 1821, and the land planted 

 in corn the same year. The coultering and after-tillage very badly exe- 

 cuted, on account of the number of whortleberry and other roots. As 

 much as was convenient was marled at six hundred bushels, 37 per cent, 

 and the dressing limited by a straight line. Distance of corn 5^ by 3^ 

 feet— 2262 stalks to the acre. 



Results. 1821. October— on each side of the dividing line, a piece of 

 twenty-eight by twenty-one corn hills measured as follows : 

 No. 1, 588 stalks, not marled, 2 busliels, equal to 7 bushels 3 pecks the acre. 

 No. 2, 588 stalks, marled, 4^: ' 16 bushels 2-| pecks. 



1822. In wheat, the remainder having been previously marled. 



1823. At rest. During the fjllowing winter it was covered with a 

 second dressing of marl at 250 bushels, 45 per cent., making 850 bushels to 

 the acre altogether.
