Chap. XXI. Gf the Wheat-Drill 373 



The Limbers G and PJ, we make of Afpen, Pop- 

 lar, or Willow, for Lightnefs ; we make them as 

 fmall and light as we can, allowing them convenient 

 Strength ; and the fhorter they are, the more exactly 

 the Drill will follow the Horfe, without the Hand of 

 him, that follows the Drill, whofe chief Bufinefs is, 

 with the Paddle to keep all the Shares and Tines from 

 being clogged up by the Dirt flicking to them, and 

 alfo to obferve whether the Seed be delivered equally 

 and juftly to all the Chanels. 



Thefe Limbers mould approach fo near together 

 at their fore Parts, near the Chain, that there may be 

 none or very little room betwixt the Limbers and the 

 Horfe •, and therefore muft be nearer together for a 

 very little Horfe than for a great one : The Horfe, 

 which I have ufed in all my Drills for thefe many 

 Years pad, is a little one, about Thirteen Hands 

 high; and the fore Part of my Drill-limbers are Twenty 

 Inches wide afunder at the Chain. 



Atg on the Outfide of the Limber G, is a fmall 

 Staple driven in, having one Link on it, which holds 

 a fmall Hook, which, taking hold of different Links 

 of the very fmall Chain I, raifes or finks the fore 

 Part of the Plough to different Heights. But take 

 care to fet it at fuch a Degree, that the fore and 

 hinder Share may go equally deep in the Ground; 

 and when they do fo, the fore Part of the Limbers 

 ought to be higher than the Traces which draw them. 



At h in the Limber H, is driven another Staple, 

 which holds the other End of the Chain ; or elfe, in* 

 Head of a Chain, v/e may make ufe of a Piece of 

 Cord, one End of which put thro* this Staple, and 

 ty'd to the Limber, and a Piece of Chain of half a 

 dozen Links, faften'd to the other End of fuch a 

 Cord, will ferve as well as a whole Chain, for raifing 

 and finking the Limbers. 



He who can by thefe Directions make this Wheats 



drill, may very eafily make any other Sort of Drill,
