IO4 THE PRACTICE OF THE 



tenfive practice, on various forts of land, and 

 cannot be dilproved by negative arguments. 



Though the horfe-hoed wheat crops are 

 very profitable, farmers are not advifed to go 

 largely into that Huibandry at fir ft, bccaule 

 it requires more Ikill and attention in the ma- 

 nagement, than other crops that do not conti- 

 nue fo long upon the ground : for which rea- 

 fon the farmer mould begin it at firft upon a 

 fmall quantity of land ; and encreafe it, upon 

 further experience. 



Mr. Tull at firft drilled three or four rows 

 upon fix-feet ridges, afterwards two rows only 

 upon narrower ridges, as mentioned above. 

 But the moft perfect culture in this Huiban- 

 dry, is of iingle rows upon ridges : for where 

 there are two or more rows upon a ridge, the 

 partitions between the rows cannot receive the 

 full benefit of the hqrle-hoeing, and are cul- 

 tivated only with hand-hoes; and it is diffi- 

 cult to get the weeds clean out of the rows. 

 It ieems to have been for thefe reafons, tbat 

 the very ingenious author of this Hufbandry 

 hegan, towards the latter end of his practice, 

 to try the culture of fingle rows of wheat 

 upon ridges ; which he tnought might an- 

 fwer, .if iingle rows of Smyrna wheat were 

 drilled upon ridges three feet and eight inches 

 broad. This wneat has one large middle ear, 

 with fmaller ears growing out from the bot- 

 tom of the middle ear, and all round it ; he 

 was promifed fome of this wheat, but difap-
