I fee in Young's Annals, an account of his ex- 

 periment of feeding hogs on potatoes, on a large 

 fcale, which did not prove very profitable. I think 

 that pigs pay lefs for their food than cattle or flieep 

 — for this reafon, their /kins yield nothing, and the 

 price is kept down by thoufands of them being fed 

 on what bad threfliers leave in the ftraw, and on 

 wafh, grains, and other tralh, which other profitable 

 animals will not eat. The wool of a Iheep is twice 

 and often three times the value of the flefti by the 

 pound ; and it is probable that, taking the whole 

 weight of the animal alive, it may require as much 

 food to produce a pound of flefti and even bone and 

 offal, as a pound of the fineft: wool worth eighteen- 

 pence or two (hillings, fuch as the Ryeland llieep 

 yield. It would be well if all farmers knew, that 

 (mall bones and light offals are very valuable qualities 

 in creatures that are to be fed and fold by weight. 



I am, with great edeem, dear fir,

• A model of one of thefe valuable machines may be feen at the 

 Society's Rooms: they are found eminently ufeful for large farmers ; 

 and fmaller machines for fimilar purpofes are now invented for fmaller
