Cultivation of Grafs Land Rolling of. 



foft by a moderate fall of rain ; but in thofe of the contrary fort it may be neceHary 

 to wait till the fupcrabundant moiflure be fo much dried up as to admit the animals 

 employed in drawing the machine without poaching, or oiherwife injuring the 

 iurface of the ground. 



A roller of confiderable weight is neceffary in performing this bufinefs in the 

 moll complete and effectual manner, fuch as has been already defcribed.* And in 

 order to prevent as much as poffible the ground from being injured by the feet of 

 the animals that draw it, as may frequently be the cafe where they follow each 

 other in the fame track : it may be the beft practice to have them yoked double^, 

 as by that means there will be lefs treacling on the fame portion of furface. Where 

 two horfes are fufficient to execute the work, more mould never be made ufe of; 

 but if a third (hould be found neceffary, it may be attached as a leader in the middle 

 before the other two: a greater number of horfes can feldom or ever be of any material 

 advantage in this fort of work. It is neceffary to be very careful in executing this 

 operation, to fee that every part receives the due impreffion of the implement. On 

 lands where this fort of work is regularly performed, it will feldom be requifite to 

 pafs more than once in a place, but in other cafes it may often be done more 

 frequently with benefit. 



The rolling of watered meadows mould be executed towards the latter end of 

 February or beginning of the following month, after the land has been left in a dry 

 ftate for a week or ten days. The work mould be performed lengthways of the 

 panes, going up one fide of the trenches and down the other.f And in rolling 

 the common hay lands, it is a good method to proceed up one fide the field and 

 down the other fomewhat in the fame manner. 



As grafs lands, efpecially thofe that have not been long refiored to the ftate of 

 fward, are fometimes liable to become thin and patchy, it may be necefTary to reftorc 

 or bring them to a perfect condition of furface, by lowing frefh grafs feeds over 

 the patches or uncovered parts. This is bcft performed as early as pofBble in 

 the fpring feafon, during moift weather, the feeds being either left to themfelves, 

 &r trodden in by folding (heep thinly upon them. Therollermay likewife be ufeful 

 ,in this view by being run over the patches, though not fo effectual as that of Iheep. 

 In this, as well as other cafes, fuch forts of grafs feeds fhould be chofen as are the 

 moft adapted to the nature of the lands. The methods of managing this fort 

 of bufinefs in the beft manner have been fhewn above. The utility of fcarifying, or
