Report of the Trials of Ploughs, Harrows, ^-c, at Hall. 535 
and is shown in Fig. 7, at a. This is both a simple and clever arrangement ; 
the wheels are attached by an ingenious arrangement, wherehy the beam is 
strengthened, and the standards firmh' secured, the attachment to the beam 
through which the axles pass give a firm wide bearing, and an open fore 
carriage. The old sliding axle is dispensed with, — an advantage, as soil and 
rubbish were apt to accumulate round it. The coulter is quite straight ; the 
fastenings, of wrought iron and steel, are easily adjusted, to give greater or less 
inclination, by moving along the heam. The skim is of cast steel, with a 
small blade attached to the arm or standard by two nuts. Ttie mouldhoard, 
which is shown in Fig. 8, is of a verj' perfect form, calculated to work clean

and lay a well-packed furrow, without absorbing an undue amount of power. 
The front portion is a flat surface, the middle part slightly convex, and the 
upper portion of the wing projects well over the under part; thus the 
necessary pressure is given without squeezing. 
J. D. Snowdon, of Doncaster, exhibited a strong, useful class of implements. 
His plough (No. 1178) comprises wooden stilts and wrought channel-iron 
beam. The former, 6 feet long, are braced so as to increase strength ; but 
are objectionable, inasmuch as the bolts, &c., become loose from the decay of 
the timber, and, liowever well made, there are parts where moisture will lodge 
and soon cause decay. It may be argued that they are easily 
renewed ; but we prefer iron as more durable. The beam, which Fig. 9. 
is very strong, being made of channel or double-flanged iron, , 
measures 6 feet 5 inches, giving a total length to the plough of r^^^ 
12 feet 5 inches. The beam is 3 inclies X 1^, by f inch in the S f ; 
channel (Fig. 9). There is no means of adjusting; the share, so as J 1 7 
to give increased pitch. The coulter is adjustable by means of a r S >1- 
bead or rib on the beam, in the same manner as already described in Cor-
