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 : 



Not marled, No. 1. ~6i 1 ,T ^ni i_ i i *

The remainder of this piece was marled before sowing wheat in 

 1821. 



1823. At rest. 



1824. In corn distance 5| by 31 feet, making 2436 stalks to 

 the acre. October llth, measured two quarter acres very nearly, 

 if not precisely, coinciding with Nos. 2 and 3 in the last measure- 

 ment. The products now were as follows : 



No. 2 brought 7 bushels 31 pecks, 1 



or per acre, .... 31.1 [-average 31.2 f. 

 No. 3 brought 8 bushels, . . 32 J

Experiment 3. 



The parte/# Ji was cut down in January, 1821, and the land 

 planted in corn the same year. The coultering and after-tillage 

 very badly executed, 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 bushels, equal to 7 bushels 3 

 pecks the acre. 



No. 2, 588 stalks, marled, 41 bushels, equal to 16 bushels 2i 

 pecks the acre. 



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



1823. At rest. During the following winter it was covered with 

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

 850 bushels to the acre altogether. 



1824. In corn. Two quarter acres, chosen as nearly as possible 

 on the same spaces that were measured in 1821, produced as follows : 



No. 1 made 8 bushels, 2 pecks, or to the acre, 34 bushels.
