Il6 THE PRACTICE OF THE 



been with only the fame tillage and propoiv 

 tion of manure. 



2. Ridges four feet broad are fufficient for 

 turnips for feeding cattle, as was experienced 

 by Mr. Tull, and by others fince. Upon 

 four-feet ridges the crop would have been 

 greater than upon thofe of five feet, in the 

 proportion of five to four; and the crop would 

 have been 58 tons, j c. 21 Ib. viz. 2 tons, 130 

 i qr. 1 1 Ib. more fuperiority per acre than 

 computed by Mr. Baker. 



3. The expence of the broad-caft was 

 much greater than of the 1 drill, for the broad- 

 caft coft 1 1. 8 s. 8 d. per plantation acre, and 

 the drilled coft but 43. 2 d. per acre, reckon- 

 ing the horfes at one (hilling a day each, 

 which is a good price there : fo that the ex- 

 pence of cultivating the broad-caft turnips was 

 above fix times as much as for the drilled. 

 This difference is very great, and would 

 amount to a large fum in cultivating turnips ex- 

 tenfively. The drawing up and carriage of the 

 broad-caft cofts alfo more than the other ; and 

 if not drawn all clean up, what is left in the 

 ground will grow, and damage the next crop, 

 efpecially if that is barley. 



4. The land where the broad-caft turnips 

 grow becomes hard and ftale, and will re- 

 quire feveral poughings to bring ijt into fine 

 tilth for another crop : whereas land that has 

 been horfe- hoed is in fine tilth, while the 

 crop of turnips are growing upon it (as Mr,
