3 6$ Of the Wheat-Drill. Chap. XXL 



the Boxes of our hinder Hoppers are ; but in the 

 fore Hopper* or any other long Hopper, we can 

 place the Brafs Seed-box to a Bottom made for the 

 Purpofe, like that in Fig, 24. where there is a Piece 

 of Board on the fore Part of the Hopper from End 

 to End, as a £, and another on the hinder Part of 

 the Hopper, as c d. Then the fore Part of the Brafs 

 Seed-box, being placed under the Piece a b, is fcrewed 

 up to it at <?, and the hinder Part of the Seed-box 

 under c d fcrewed up to it at/-, then the Bottom of 

 the Hopper, being open in the Middle, is (hut by very 

 thin Boards, ^ and h, fixed up to the mentioned Pieces : 

 Thefe Boards having their upper Surface even with 

 the upper Edges of the Brafs Box* the Seed can no 

 way arch in coming into the Mortife of the Seed-box. 

 Whichever of thefe Two Methods be made ufe of, 

 in a long Hopper, the Bottom muft be fixed to the 

 Two Sides, by fmall Bars of Wood of about Three 

 quarters of an Inch fquare, to which the Bottom and 

 Sides are faflened by Nails, in the manner that the 

 Ends and Sides of the hinder Hoppers are faftened to 

 their Polls, which (land in their Corners. 



We take the fame Method for cutting the Notches 

 in this Spindle, as has been defcribed tor cutting the 

 Notches in the other Spindle. 



But obferve, That the great Length of this Spin- 

 dle requires it to be the larger -, and we make it of an 

 Inch and Three quarters Diameter, the other being 

 only an Inch and an half: We therefore bore the great 

 Hole or Cylinder of its Brafs Seed-box a quarter 

 of an Inch in Diameter larger than of the Brafs Seed- 

 boxes of the hinder Hoppers ; and we commonly 

 make a Notch more in the Circumference of this 

 Spindle, becaufe the Semidiameters of its Wheels 

 muft be as much greater than of the hinder Wheels, 

 as is the Thicknefs of the Plank, and the Ends of 

 the Limbers which are betwixt this Spindle and the 

 i;pper Surface of the Two Beams.
