Surface, the Spindle being alio exaclly parallel to the 

 fore Edge of the Plank. 



Fig. 10. is D in the Plough Fig. 1. It is Two 

 Feet long, Two Inches broad in its narrowed Part, 

 and half an Inch thick in the thinneft Part, and Two 

 Inches at its Shoulders above the Plank. It is pinn'd 

 thro' the Plank before the Funnel, having one of its 

 Legs on each Side the Tenon of the Sheat : It ftands 

 perpendicular to the Plank : Its only Ufe is to hold 

 the fore Hopper from turning upon the Spindle, be- 

 ing put thro' a thing (Fig. 22.) like the Carrier of a 

 Latch, nail'd on to the upper Part of the fore Side 

 of the fore Hopper, in which thing this Standard has 

 room to play, or move fide-ways, to the end that 

 either Wheel may rife up. 



Fig. 11. is one of the hinder Standards, which 

 being placed in the Beam, as G or H, perpendicular 

 to it, is driven into a Mortife, and pinn'd into the 

 Beam. It has a Shoulder behind, and another before, 

 and a Third on its Outfide ; which Shoulders ferve 

 inflead of Braces, to keep it from moving backwards, 

 forwards, or outwards : It is Two Feet Four Inches 

 long, Two Inches broad, and an Inch thick : It is 

 placed with its broad or flat Sides towards the Sides 

 of the Beams. It is made fo thin, becaufe it mould 

 have the more room for the Hopper to play on it ; 

 and therefore muft have its Strength in its Breadth. 

 The Part at a muft ftand foremoft. 



The Standards G and H are both alike, except as 

 they are oppofite : Their Ufe is to draw, guide, and 

 hold up the hinder Hopper : They are to be placed 

 perpendicular to' the Beams, and at equal Diftance 

 from each Side of thofe Beams, and at fuch a Diftance 

 before the Funnels, that v/hen the fore Side cf the 

 Hooper by its whole Length bears againft the hinder 

 Surface of the Standards, the Seed may drop into the 

 Middle of both Furinels, the Plough ftanding upon 

 an horizontal Surface*
