_Fig._ 12. is one End of the hinder Hopper laid open. I call it one End (altho’ it be an intire Box by itself) because this Hopper is supposed to have its middle Part cut out, to have a clearer Sight of the Plough, and fore Hopper; as is seen in _Fig._ 15. which is the whole Hopper in Two Parts. In this _Fig._ 12, A is the Inside of one End of the Hopper, made with several Pieces of half-inch Elm-board nail’d on to the Post _c a_, on the fore Side; which Post is a little more than half an Inch square, and Seventeen Inches and Three quarters long, being the Depth of that Part of the Hopper which holds the Seed. B is the fore Side of this Hopper; which must be nail’d on to the said Pod, being of the same Length with it, and Four Inches broad, and half an Inch thick; and this is the Part which on its Outside goes against the right-hand Standard of the Plough, when it is at Work. The other Post _b d_, of the same Thickness with the former, is nail’d in within half an Inch of the opposite Edge of this End; to which Post also C being nail’d, makes the hinder Side of this Part of the Hopper. C is Four Inches broad, and half an Inch thick; and both it, and the Post to which it is to be nail’d, are something longer than its opposite Side, because the Side B makes right Angles with the Top and Bottom of the Hopper; but the hinder Side C makes oblique Angles with the Top and Bottom of the Hopper; and the Reason of this is, because when the Hopper is full of Seed, it may be equally pois’d on the Spindle; which it could not be without this Bevel, unless the Bottom of the Hopper did come as much behind the Spindle as before it; and that would hinder the Person that follows the Drill, from seeing the Seed fall out of the Seed-box into the Funnel; and that Part of the Bottom which is before the Spindle cannot be made shorter, because that Part of the Seed-box which is before the Spindle, is (upon account of its Tongue) much longer than the Part of it which is behind the Spindle. ’Tis true that when the Hopper is empty of Seed, it cannot be thus pois’d; but then, being so light, it does not require it. _e f g h_ is a Piece of a Board, nail’d on to that Part of the End A, which is below the Bottom of the Cavity which holds the Seed, and is commonly plac’d a little cross the Grain of the Board to which it is nail’d, and serves to strengthen it, and keeps the Hole _i_ from splitting. The upper Edge _e f_ of this added Piece of Board is exactly the Length of the Bottom of the Hopper, whereto the Brass Seed-box is fastened; and this Bottom, together with its Seed-box under it, being put into its Place, bears upon this Piece from _e_ to _f_, which holds Up the right Side of the Bottom, and keeps it from sinking downwards; as the lower Ends of the Two mention’d Posts, and the fore and hinder Side B and C nail’d to them, prevent its rising upwards.
