curnstanee done away, there remains no reason for 

 any farmer, on a soil where the drill machine can 

 freely move, rejecting the husbandry ; and he cer- 

 tainly ought to apply it in such cases as it is better 

 adapted to, than dibbling, which, however, never 

 made any progress for barley. 



Upon soils of such tenacity as deny effect to 

 liollow drains, the system of drilling miist be dif- 

 ferent ; such soils must be laid on round high 

 arched ridges, and to drill these to advantage will 

 demand a machine made for the purpose. 



BIDGES, STITCHES, OR LANDS FOR DRILLING. 



Drilling, if performed on ridges, demands those of 

 Tarious breadths, according to the system intended 

 to be pursued. Some farmers prefer such as admit 

 but one, stroke or movement of the drill-machine ; 

 others prefer a bout, or two movements. Suppose 

 the machine sows six rows at one foot; that one 

 foot be allowed for the ridge-furrow, and that one 

 movement is preferred: in this case, the ridge must 

 be six feet wide, always measuring from centre to 

 centre of the furrows ; but if eighteen inches be 

 allowed for the furrows, which will make better 

 work, then the ridges must be six feet six inches. 

 Two- movements of the machine will demand in the 

 former case eleven feet, and in the latter, thirteen 

 feet six inches; and thus, in all other distances,, 

 the measure is ascertained on the same principles i 

 but where, from the dryness of the soi! 9 the ridges 

 are ploughed to a great breadth, or the land quite 



flat,
