J. P. Ftson. No. 2996. — The wrought-iron beams are composed of 23-inch 
rods or bars f-inch thick, and arc somewhat slight even for light work ; they 
are connected by screws working through holes, and are supported by two 
screw-bolts. The adjustment is from 7 to 9i inches ; and at the greater width 
the attachment is least strong, which is a defect. The narrower the furrow 
the more the connections overlap. The draught is taken from the back part of 
the beams by a rod -^^ inch thick, attached to a |-inch pin, which is decidedly 
light. The mouldboards measure 3 feet 11 inches from the front of the share, 
inches deep, and the wings of the share measure li inches. The back, or 
second plough, has a slade 11 inches long; and a vertical friction-wheel sup- 
ports the frame behind. This wheel admits of adjustment. This plough has 
no lifting apparatus ; it is light in constrifction, and likely to answer on very 
light land. The price, without extras, is 81. 15s. ; steel breasts, skim coidters, 
drag chain, and steel side cap, add 11. : Total, 9^. 15s. The furrow was well 
cut and laid, the bottom even, and the work well done. 
J. Hodgson. No. 1723.— A short description will suffice for this implement, 
which was roughly turned out and unfit for competition. The stilts, 6 feet 
2 inches in length, are of wood, and, though less costly at the first start than 
iron, the want of durability is a serious objection, as, after a time, the wood 
suffers, and a certain degree of play and want of tautness is perceptible. The 
beams are 5 feet 7 inches in length, by 2t inches by i inch thick, which is not 
strong, though probably equal to light-land ploughing. The outer beam is 
very short, and is adjustable by two screws and nuts. The friction-wheel 
behind runs at an angle. The draught is from the front of the second plough. 
The slade on the back jjlough is 15 inches, that on the front plough is 
10 inches only. The plough has no mechanical arrangements to assist turning 
at the headland. The construction was so weak that the arm of the furrow 
wheel bent, and eventually the machine broke down. 
G. W. Murray and Co. No. 3501. — The whole of this plough is of wrought 
iron, which, though increasing cost price, insures great strength and durabilitj'. 
The beams, which exjiand, allow of a furrow of from 6 to 10 inches ; the adjust- 
ment is effected by one screw and slot behind, and in front by one pin, which
