Ground, and that will fhew the Neceffity of it; but 

 there is no occafion to muzzle the Horfes until the 

 Plants are grown as high as their Nofes, when rein'd 

 up, as in Fig. 4. 



Fig. 6. is an Inftrument of Pulveration, which 

 might have been fufficiently defcrib'd by its Matter, 

 Weight and Dimenfions, without any Portrait, were 

 it not to fhew the particular Manner of drawing it ? 

 being very different from that of a common Roller, 

 whofe Frame is difficult to make, and coflly \ but 

 this, being only Three Feet long, is drawn by a 

 fimple Pair of Limbers, held together, by the Two 

 Bars A and B, firmly pinn'd in at their Ends. 



Its Gudgeons mud not come out beyond the outer 

 Surface of the Limbers, left they mould take hold of 

 the Plants, when drawn in the Intervals ; alfo the 

 hinder Ends of the Limbers, behind the Gudgeon, 

 fhould crook a little upwards, for the fame Reafon. 



This Stone Cylinder is Two Feet and an half Dia- 

 meter, and weighs Eleven hundred Weight befides 

 the Limbers. It mufl never be us'd but in the drieft 

 Weather, when neither the Plough nor Harrow can 

 break the Clods ; and then being fo very ponderous 

 and fhort, it crufhes them to Powder, or into fuch 

 very fmall Pieces, that a very little Rain, or even the 

 Dews (if plentiful), will diflblve them. 



I have had great Benefit by this Roller in preparing 

 my Ridges for Turneps. The Weather proving dry 

 at Midfummer (which is the belt Seaibn for planting 

 them), the Land was in Pieces like Horfe-heads, i~Q 

 that there was no Hope of reducing them fit for plant- 

 ing with Turneps that Year; the Gods being fo very 

 large, that they would require fo many Viciffitudes of 

 wet and dry Weather to flack, them; but this Inftru- 

 ment crufh'd them fmall, and the Plough following 

 it immediately, the Ridges were harrow'd and drilFd 

 wich very good Succefs.
