132 fH'E PRACTICE OF THE 



good and favourable to that Hufbandry, as ap* 

 pears in the examples of it given above. Mr. 

 Craik's is not good land, and his climate is 

 very unfavorable ; yet the clear profit of his 

 drilled wheat is to the value of 1 6 or 1 8 bum- 

 els of wheat per acre; the lead of thefe is 

 four pounds an acre : where is the farmer 

 that in the common Husbandry gets fo much 

 as four pounds per acre for the average crops 

 of his lands that he fows once in three or four 

 years with wheat, and the intermediate years 

 with turnip's, barley, and clover ? His crops 

 of wheat may be greater than Mr. Craik's ; 

 but can he obtain thefe crops at fo fmall an 

 expence as the value of eight bumels of wheat, 

 or forty millings ? The more manure he lays 

 upon this land, the greater will be the expence 

 of it, and of the carriage and fpreading of it ; 

 and it is often uncertain, becaufe it depends 

 upon the feafons, whether highly manuring 

 of land mall be a benefit or an injury to a 

 crop of wheat or other corii ; for in very dry fea- 

 fons much dung burns the crop, and in wet 

 feafons it makes the crop too luxuriant, and 

 then it lodges and is blighted. 



In many farms, where manure is fcarce, 

 the farmer's principal dependence is upon his 

 fheep to drefs his land ; but, where there are 

 not extenfive downs and meep-walks, the 

 farmer makes nothing of his poor land, nor 

 attempts to do it, for want of manure : many 

 hundred thoufand acres, thus negleded, let
