advantages claimed for this peculiar breast and point are, that no matter at 
what ant;le the lower frame is fixed, the diamond point and a sharp cutting 
edge is always facing the work. The action of the radial breasts is to lift the 
soil and leave it particularly light, and in a favourable condition for atmospheric 
action. In dirty land there is no possibility of choking, and the 
weeds run up the face of the breasts, and owing to the twisted Fio". 105. 
form they clear well : this answers well for certain operations, 
but before Mr. Murray's cultivator can be made adaptable to a 
variety of different conditions, it%ust be furnished with addi- 
tional tines and shares, such as narrow chisel points, broad 
flat shares, &c. The crank axle also requires alteration, being 
too long and weak. The travelling wheels are 2 ft. 10 in. dia- 
meter, with wrought-iron |r spokes and 2s in. rims. The price 
marked in the catalogue is lOZ.'lOs. 
Corhett and Peele. No. 2855. — This firm exhibited similar 
implements in both classes of cultivators, differing only in the 
substance of iron employed in the frame ; this was not suffi- 
ciently strong for heavy land, but the article under review, 
which competed in Class 27, was much noticed by the Judges, 
and one of the four selected for final trial. The chief novelty consists in the 
arrangement for lifting the frame, which is effected by a crank axle of hind 
wheels, and by a leverage on the fore-wheel carriage arm ; a chain attached to 
the top of this arm runs under a pulley-wheel on the cultivator frame, and termi- 
nates by a rod on the lever arm from the wheel axle ; by pulling down the lever 
arm the fore part of the frame is raised, by the chain lifting it up ; and the 
travelling wheels are brought forward into a vertical position, by which the hind 
portion of the frame is raised. Depth in work is regulated by fixing the lever 
handle by a pin or stop bar. The following sketch (b'ig. 106) made in the 
field, and not drawn to scale, will give a better idea of the mechanism.

W. Hunt. No. 1636. — Here again we have an infrenious leverage, which 
will be understood by reference to Fig. 107, p. 600. The principle is'much the
