3 yo Of the Wheat-Drill Chap. XXL 



We make thefe Wreaths a little different from the 

 other Sort of Wreaths, which turn againft the Holes; 

 we make them of a greater Diameter, left they fhould 

 at any time get in betwixt the Legs of the double 

 Standards, in cafe the Standards mould be loofe, or 

 bend : Therefore we make the Diameter of each of 

 thefe Wreaths, at lead, Two Inches and Three quar- 

 ters : We always make them of Wood, and of a pe- 

 culiar Shape, takingoff their Edges next the Standards, 

 which Edges would be an Impediment to the Rifing 

 of one End of the Spindle without the other. So 

 that, for making thefe Wreaths, we may form a Piece 

 of Wood of the Shape of a Skittle-bowl (or an ob- 

 late Spheroid J having an Inch and Three-quarter 

 Hole bor'd thro' its Middle, and then cut by its 

 Diameter (which is about Three Inches) in Two 

 Halves, each of which will be one of thefe Wreaths; 

 and they mud be placed on the Spindle, with their 

 convex Sides bearing againft their respective Standards. 



The Diameter of the fore Wheels is about Thirty 

 Inches, as the Diameter of the hinder Wheels is about 

 Twenty-two. 



The fore Spindle mould be of fuch a Length, that 

 its fquare Ends, E and F, may come out Three or 

 Four Inches farther than the Hubs (or Stocks) of the 

 Wheels; fo that there may be room to fhift the 

 Wheels towards either End, for making feveral Sets 

 of Notches, for the Ufe of the Seed- box. 



Obferve, Tho* the fore Hopper is drawn by its 

 Spindle, yet the hinder Spindle is drawn by its 

 Hopper. 



The Reafon of this great Diftance between the 

 Two fore Wheels is not fo much for their ferving 

 as Marking Wheels to this particular Drill ; which be- 

 ing drawn only upon a Ridge, its 1 op is a fufficient 

 Direction for leading the Horfe to keep the Rows pa- 

 rallel to one another, if the Ridges are fo-, but if the 

 Wheels were much nearer together than they are, and
