 Angle with the Horfe-path, and then the Plough will 

 not perform at all. Therefore it being necefTary, that 

 the Share always go parallel to the Horfe-path, and 

 often as necefTary that the Plank go at oblique Angles 

 to the Horfe-path ; it follows then that the Beam fland 

 at oblique Angles with the Plank, to preferve the Pa- 

 rallelifm to the Horfe-path ; and this cannot be done 

 but by the Holes which are fhewn under the pricked 

 Lines which crofs the Plank. 



The Holes A, B, C, are thofe to one of which 

 the Beam is icrewed up by its Hole G, in Fig. 2. 

 Thefe Holes are made as near to the hinder Edge of 

 the Plank, as they can fafely be, without Danger of 

 tearing out; which is generally about an Inch diftant 

 from the faid Edge. 



Every one of thefe Ploles are anfwered by Three 

 others, near the fore Edge of the Plank, as the Hole 

 B has, at the fore Edge of the Plank, the Holes D, 

 E, F. D, E belong to the Hole I of the Beam 

 Fig. 2. Thefe Two Holes are made as near together 

 as they can be without breaking into one another. 

 F anfwers the Hole H in Fig. 2. and is made between 

 D and E, as near them as fafely it can. 



When the Beam is fcrewed up at B and F, and 

 makes the fame Angles with the Plank, as the pricked 

 Line be doth ; then the Draw-pin {landing in the 

 Hole 8 or 9, will bring the Plough lb much to the 

 Left, that the Share will point too much towards the 

 Right; then remove the fore End of the Beam to the 

 Hole D, and then the Beam will make the fame Angle 

 with the'Plank as the pricked Line c d, which may 

 bring the Share to be parallel to the Horfe-path nearly 

 enough : But if the Draw-pin mould be placed in the 

 Hole 1. then the Plank would go fo much on the 

 Right of the Horfe-path, that the Share would point 

 vafily too much towards the Left, ftanding in either 

 of thefe Two Pofitions : Therefore the roremoft Pin 

 mud be removed to the Hole E, and then the Beam
