Even hay^ an article of conftant confumption^ 

 cannot, on account of its being fo very variable in 

 its quality^ be reduced to any ffcandard price. But 

 even that article is regulated by the price of butter. 

 For, as the fame land which produces hay for fale 

 (efpecially near great towns, v/here the demand both 

 for hay and butter chiefly is) would alfo keep dairy 

 cows, the quantity of land mo-wm for hay will 

 always be regulated by the price of the produce of 

 fuch cows. 



And by parity of reafoning, it may be faid with 

 truth, that the price of lambs and wool is as much 

 regulated by the price of butter, as the price of hay 

 is ; for almofl: all grafs land may be fed with cows* 

 And butter being, as is before explained, the article 

 of daily confiimption and daily return ^ and therefore 

 governing the price of cheefe, and other produftions 

 of grafs land, whofe fale and whofe return is more 

 dijiant, it follows, that every occupier of grafs land 

 will apply it to that purpofe which he finds to an- 

 fwer beft. And that kind of exertion will always 

 operate fo as to keep the profit (and of courfe the 

 tithe) of all the various articles produced on the fame 

 kind of land, nearly on a level. 



And even underwood (from which, In forae coun- 

 tries, a confiderable tithe arifes) will be grubbed up, 

 and made pafture land, the moment it is found that 

 the fa?}ie land would pay better, if fed by Jheejf or 

 cows. If
