ON NEW AND ACID LAND. 121 



1823-4. The lines p q and r s divide the piece nearly into quar- 

 ters. The end nearest Ap o is lighter, and best for corn, and was 

 still better for the first crop, owing to nearly all that half having 

 been accidentally burnt over. After twice coultering, marl and 

 putrescent manures were applied as follows; and the products 

 measured, October llth, the same year.

 p w, marled at 450 bushels, brought not so good a crop 



as the adjoining r p at 800. 



The distance was 5 by 3 feet. Two of the quarter acres were 

 measured by a surveyor's chain (as were four other of the experi- 

 ments of 1824), and found to vary so little from the distance 

 counted by corn rows, that the difference was not worth notice. 



1825. In wheat, the different marked pieces seemed to yield in 

 comparison to each other, proportions not perceptibly different from 

 those of the preceding crop but the best not equal to any of the 

 land marled before 1822, as stated in the 1st, 2d, and 3d experi- 

 ments. 



1827. Wheat on a very rough and imperfect summer fallow. 

 This was too exhausting a course, (being three grain crops in the 

 four-shift rotation), but was considered necessary to check the 

 growth of bushes that had sprung from the roots still living. The 

 crop was small, as might have been expected from its bad pre- 

 paration. 



1828. Corn in rows five feet apart, and about three feet of 

 distance along the rows, the seed being dropped by the step. 

 Owing to unfavourable weather, and to insects and other vermin, 

 not more than half of the first planting of this field lived ; and so 

 much replanting of course caused its product to be much less -ma- 

 tured than usual, on the weaker land. All the part not marled 

 (and more particularly that manured) was so covered by sorrel, as 

 to require ten times as much labour in weeding as the marled parts,
