 heat of the body. 



LET us now make fomc practical obferva- 

 tions with regard to the management of 

 dunghills : for this is an affair of confider- 

 able importance, and in which farmers feem 

 to be very ignorant. 



DRY vegetables require a conliderable 

 degree of moifture before they can be 

 brought to putrefy. I think dunghills are 

 generally kept too dry, as they are com- 

 monly in this country placed on a high 

 iituation, and are themfelves raifed to a 

 confiderable height. A hollow fituation, 

 which will retain the moifture, is the beft. 

 Too much moifture is likewife bad. This 

 may be prevented by having hollow places, 

 with clay bottoms, at the fide of the dung- 

 hill, into which the fuperfluous moifture 

 may be allowed to run, and from whence 

 it may be reftored again by pumps to the 

 dunghill at pleafure.
