has grown up, in fpite of them, to the perfection to 

 which it has now attained. Nay, indeed they may 

 be faid to have contributed in fome degree to bring it 

 to that perfedio7i, by putting landholders upon ex- 

 pedients to raife fuch crops as were the lead advan- 

 tageous to the tithe-owners and the mofl: beneficial 

 to themfelves, and which have tended ultimately fo 

 much to the advantage of the kingdom, viz. the 

 laying down ivet arable lands to pajlure, and the 

 raifing artificial grajfes, turnips, and other green crops 

 upon arable land, inftead of exhaufting the land, as 

 formerly, with repeated crops of corn. A fyftem 

 which has enabled the kingdom to fupply its in- 

 creafed confumption of animal food, for which it 

 mud always depend upon its own refources, almofl 

 unalTifted by importation. 



And this alteration in the agriculture of the king- 

 dom has made the value of tithes fo very uncertain 

 and fluctuating, that, although in particular diclricts 

 it has been very much increafed by the bringing large 

 trafts of uncultivated land into tillage, it has de- 

 creafed in other di/lrids, particularly in the neigh- 

 bourhood of great towns, in proportion as the value 

 of the land has increafed by the introduction of good 

 hufbandry. 



And perhaps this uncertainty of the tithes, arifmg 

 from the openings which this choice of crops leaves 

 for fubterfuges and evafions, and confequently of 



difputes.
