There are Two Methods for letting the Seed pass from a long Hopper into the Seed-box. The first is that of cutting the Hole through its Bottom, in the manner that has been shewn in _Fig._ 14. The other is that which cannot be used in a Hopper so short as the Boxes of our hinder Hoppers are; but in the fore Hopper, or any other long Hopper, we can place the Brass Seed-box to a Bottom made for the Purpose, 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 b_, and another on the hinder Part of the Hopper, as _c d_. Then the fore Part of the Brass Seed-box, being placed under the Piece _a b_, is screwed up to it at _e_, and the hinder Part of the Seed-box under _c d_ screwed up to it at _f_; then the Bottom of the Hopper, being open in the Middle, is shut by very thin Boards, _g_ and _h_, fixed up to the mentioned Pieces: These Boards having their upper Surface even with the upper Edges of the Brass Box, the Seed can no way arch in coming into the Mortise of the Seed-box. Whichever of these Two Methods be made use of, in a long Hopper, the Bottom must be fixed to the Two Sides, by small Bars of Wood of about Three quarters of an Inch square, to which the Bottom and Sides are fastened by Nails, in the manner that the Ends and Sides of the hinder Hoppers are fastened to their Posts, which stand in their Corners. We take the same Method for cutting the Notches in this Spindle, as has been described for cutting the Notches in the other Spindle. But observe, That the great Length of this Spindle 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 Brass Seed-box a quarter of an Inch in Diameter larger than of the Brass Seed-boxes of the hinder Hoppers; and we commonly make a Notch more in the Circumference of this Spindle, because the Semidiameters of its Wheels must be as much greater than of the hinder Wheels, as is the Thickness of the Plank, and the Ends of the Limbers which are betwixt this Spindle and the upper Surface of the Two Beams.
