By means of one of these yards, I fattened 88 

 hogs in sprii; , with only one man to attend 



them ; whereas three would not have heen suffi- 

 cient without such conveniences. They were lit- 

 tered with nine loads of straw and haulm, that 

 cost 61. 18s. ; and this made 90 loads of very rich 

 dung, valued by several farmers on the spot at 5s. 

 a load.

But they had not half the litter they ought ; 

 they would have made 3ol. worth of manure, be- 

 yond doubt. 



Ninety loads costing 61. 18s. is Is. 6d. per load. 



These particulars surely must prove the vast im- 

 portance of such conveniences, for fattening great 

 numbers of swine, for the mere purpose of raising 

 manure. Suppose the expence, timber included, 

 to be HOl. and the interest called 5l. what com- 

 parison is there between the expence of 5l. a year, 

 and the prodigious utility of having it always in 

 your power to fatten, with scarce any expence 

 of labour, whatever number of hogs you please ? 

 With such a convenience, all the pease, beans, 



barley.
