receive; and that earth, of whatever kind it be,

 general, provided the heat and moifture be equally 

 adjufted. But in this I am inclined to think Mr. 

 Tull is miftaken. 



His inftance that rufhes, when taken from a 

 low watery ground, and planted on a dry hill,- will 

 grow and flourifh there, provided a plenty of 

 water be given them, does not prove his pofition : 

 For in this cafe, by the addition of water, the 

 ftate of the foil is changed, and becomes ft mil at 

 to that from whence the rufhes were taken, and 

 which is natural to them. 



There is (as I before obferved) a fpecifick diffe- 

 rence of foils, and of the plants naturally growing 

 in each. 



The great care of the farmer ought therefore 

 to be, by proper mixtures, to reduce his land to 

 that ftate and temperament in which the extremes 

 of hot and cold, wet and dry, are bed corrected 

 by each other ; to give them every poffible ad- 

 vantage flowing from the benign influences of fun 

 and air; to adopt fuch kinds of plants as they 

 afford in this ftate the greateft nourifhment to; 

 and to renew their fertility by a judicious allow-
