Be fure to take care, that the Sheats, Funnels, and 

 Standards, be fo placed, that the Spindle of the Hop- 

 per may be at right Angles with the Beams. 



Q^ and R Part of the Limbers, which are alfo 

 called Shafts, Sharps, and Thills \ from whence the 

 Horfe that goes in them is calPd a Thiller. Thefe 

 Limbers are fcrew'd down to the Plank, by Two 

 Screws and Nuts each. The Limbers are kept at 

 their due Diftance by the Bar S ;• near each End of 

 which Bar, there is a Staple with a Crook underneath 

 each Limber, to which is hitch'd, or fattened, a Link 

 of each Trace, for drawing the Plough. This Bar 

 is parallel to the Plank, and Seven Inches and an 

 half before its fore Edge. 



The Limbers mud be mounted higher or lower at 

 their fore Ends, according to the Height of the Horfe 

 that draws in them ; and this may be done by the 

 Screws that hold them to the Plank, and by cutting 

 away the Wood at the Two hinder Screws, or at the 

 Two foremoft Screws, or by Wedges. 



Every Workman knows how to team the Limbers*, 

 that is,' to place them fo on the Plank, that the Path 

 of the Horfe, which goes in the Middle betwixt them, 

 may be parallel to aril the Shares, and fo that a Line, 

 drawn rn the Middle of this Path, might fall into a 

 ftrait Line with the fore Share, Handing on the fame 

 even Surface with the Path; for otherwife the Plough 

 will not follow directly after the Horfe, but will in- 

 cline to one Side. 



The Ufe of the Trunks of this Plough is for make- 

 rng the Chanels narrow, of whatfoever Depth they 

 are : But, without Trunks, the Chanels muft be made 

 wide by Ground-wnfts, which fpread the Sides of 

 the Chanels wide afunder, to the end that they may 

 He open for receiving of the Seed ; and the deeper 

 they are, the wider they muft be : By this Width of a 

 Chanel, the Seed in it is with mare Difficulty cover'd, 

 and the Chanel fill'd with the large ft Clods, and the 



Seed
