the arms. The slade or land side is 2 feet 11 iuchcs long, square for 3 iochcs, 
and then bevelled off to meet the surface of the frame, which is also bevelled 
in the centre, in order to allow of high-cut work, which is much approved of in 
the district where these ploughs are made (see Fig. 4, which shows the be- 
velled surlace of the frame and the form of the mouldboard). By this arrange- 
ment Ij-inch cut can be given to the furrow. The pitch of the share is 
regulated by a lever neck working in a ratchet. The coulter is adjustable by set 
^ screws and a bead on the beam. The mould- 
^^o- ^* board is stayed by an iron jilate. 111 inches 
~L by -J inch thick. This gives great strength. The 
b _l wheel fiistenings are strong and simple, and com- 
]ivise a wrought-iron box (a, Fig. 5) with screw (6). 
J j The wheel-arm has two distinct supports ; one 
1 being the box, and the other the opening in the 
beam. In this plough the maximum width 
from the land-side to the widest part of the 
mouldboard was 15 inches, whereas in both 
_] Hunt's and Ball's ploughs the width was 17 
inches ; consequently the horse-track was too 
I narrow for good work. The object of this ar- 
rangement was, doubtless, to lessen the draught ; 
but it is objectionable, as a wide horse-track is very important, in order that the 
work be not trodden on and injured. 'J'ho draught in this plough is from the cock. 
William Hunt, Leicester. Nos. 1627 and 1628. — These ploughs are well 
made ; the beam, which is of wrought iron, varies from f to 1 inch thick by 
2j to 2f inches in depth, according to the class. The cast-metal body is 
attached by four bolts. The arrangement for altering the pitch of the share 
is peculiar and meritorious ; the slade or sole plate is hinged on the front bolt, 
as shown at a in Fig. 6, instead of being fixed ; an eccentric is fitted to 
Figs. 6-8. — Illustrations of Mr. William Runt's Ploughs,

the end of the slade shown at h, by turning which any required pitch is given, 
and the wear of the slade compensated for ; thus preserving an unbroken curve 
from the point of the share to the extremity of the turnfurrow. The share 
being fixed is always firm, and no soil can collect between the share and the 
turnfurrow. The share is held in place by a stud attached to a rod, and 
regulated by a screw; the screw works in the backstay of the mouldboard,
