the lower Part of the Plough-tail at the Ground; the 

 Ground-wrift has feveral Holes at the upper Side 

 of its broadeft End, as at b, in Fig 9, by which it 

 is nailed to the lower Part of the Drock T, as in 

 Fig. 3. which Drock with its Perforations is fhewn in 

 Fig. 11. 



Fig. iz. Is the Earth-board, with its Infide up- 

 wards ; the Notch a b (hews the Rifing of the Wood, 

 which takes hold of the Edge of the Sheat, to hold 

 it the firmer, to which it is fattened by the Holes c 

 and d - 9 and at the other End it is fattened to the 

 Drock, at the Hole e. All which is km as it ftands 

 mark'd with W, in Fig. 3. But this Pin, with 

 which it is fattened to the Drock, is bigger in the 

 Middle than at each End-, which prevents the Earth-

The fhort Handle S is Fig. 14. and is long Three 

 Feet Nine Inches, pinned to the hinder Sheat (being 

 Fig* 1 5-) by the Hole a^ and to the Top of the Fore- 

 fheat above the Beam by the Hole b. 



The Handles are made fo long, for the more eafy 

 guiding of the Plough ; but the lazy Ploughman is 

 apt to cut them off fhorter, clofe up to the Plough, 

 to the end that, bearing his whole Weight thereon, 

 he may in a manner ride inftead of walking ; but if 

 he mould thus ride on long Handles, he would tilt up 

 the Fore-end of the Beam, and saife the Share out of 

 the Ground. The
