52 IMPROVEMENTS IN THE CULTURE OF VEGETABLES. 



objects which at present employ me are, I conceive, of great 

 importance to agriculture. 



The first is by experiments to ascertain the best and most 

 productive mode of applying manure. The second is to de- 

 termine, whether the distances between the stitches in drill 

 husbandry may not be greatly enlarged, without any dimi- 

 nution of crop. 



Best mole of I am strongly inclined to believe, that, where the ground.

so doing the evaporation is retarded, and consequently the 



manure continues for a greater length of time to furnifh

proves the tilth, but furnishes a greater degree of moisture 

 by exhalation, than can be yielded from ground in that 

 state of hardness it soon acquires when undisturbed in sum- 

 mer. This evaporation is prodigious, though not per- 

 ceptible to the eye : it is, however, fully demonstrated by 

 a very ingenious experiment of the Bishop of Llandaff.; 

 and I am anxiously expecting to form such conclusions from 

 trials I am engaged in respecting its effects on vegetation, 

 as may deserve the consideration of the Society. 

 Feeding cattle My former objects of feeding cattle with potatoes, sup- 

 and horses plying milk to the poor *, &c, are pursued with increased 

 success. The use of potatoes as a food for horses and cattle 

 increases daily.
