Chap. XXIII. Of the Hoe-Plough, &c. 59 y 



the pricked Line a b, before the Holes are bored, 

 which will prevent the Grain of the Wood from being 

 forced out of one Hole into the other; or thefe Holes 

 may be plated with Iron above and below, which will 

 have the fame Effect, and then there need not be 

 more than One Inch between Hole and Hole. 



Fig. 3. is the Plank apart, which by its Holes, and 

 pricked Lines, fliews the different Manner of placing 

 the Beam, a, a, a, a y are the Four Hoks for fcrew- 

 ing down the Limbers to the Plank. 



Suppoling the Path of the Horfe to be a ftrait Line, 

 and the pricked Line h i (which is at right Angles 

 with the Plank, and equidiflant from each Limber J 

 to go exactly over it, without making any Angle on 

 either Side of it ; then the Beam mud be placed at 

 right Angles with the Plank, to the End that the 

 Share may go parallel to the Horfe-path, excepting 

 that very fmall Inclination that its Point has to the left, 

 fhewn by the pricked Lines in Fig. 1. of Plate 1. But 

 this Plough feldom follows the Horfe in that manner. 

 The faid pricked Line h i generally makes Angles 

 with the Horfe-path ; elfe when the Beam flood near 

 the left Limber, and the Draw-pin near the right 

 Limber in the Hole 9. (which it mull: do to keep the 

 Share parallel to the Horfe-path) the Weight of the 

 right End of the Plank and its Limber would be too 

 heavy for the right Hand of the Holder to manage; 

 and if the Draw-pin be removed (fuppofe) to Hole 7. 

 the Parallelifm of the Share with the Horfe-path will 

 be loft, and the Point of the Share may be inclined 

 too much towards the Left; and when a Furrow is to 

 be plowed on the right Side of the Horfe-path, the 

 Beam muft be removed nearer to the Middle of the 

 Plank, and the Draw-pin muft be placed on the left 

 Side of the Beam, fuppofe to the Hole 2. This will 

 bring the greateft Part of the Plank to the right Side 

 of the Horfe-path ; and then the Share, flanding at 

 right Angles with the Plank, will make a very large 



Angle
