Report of the Trials of Ploughs, Harrows, ^t., at Hull. 58.') 
whether thoj are correctly described or no, there is no doubt of 
the great value of these implements. And we need only contrast 
the admirable specimens shown by Mr. W. Ashton, of Horn- 
castle, with the old wooden Drag Harrow, to be convinced of 
their value and economy. It frequently happens that land 
which has been ploughed some little time has become consoli- 
dated to such an extent that straight-toothed harrows fail to 
lighten up the soil sufficiently for a healthy seed-bed ; for such a 
case the Chisel Harrow is invaluable. On light soils it acts 
as a cultivator, and succeeds admirably, provided the land is not 
very dirty ; the only difference between the Chisel and Duck- 
foot Harrow is in the termination of the tines, the one being 
square, the other rather pointed in the centre. 
Mr. W. Ashto7i was highly successful, taking first prizes in three classes— 
his chisel harrow being specially commendable for the ease and rapidity with

which the depth can be altered by j-inch increments. The frame is carried 
on wheels, having a crank axle ; a lever handle from the axle canies a spring 
catch working in a notched ratchet bow. Thus the tines can be worked from 
h inch to a foot deep, or taken up out of ground altogether, and the movement 
is instantaneous. The foregoing sketch (Fig. 85) shows the implement. The 
frame combines strength with lightness, and is equally adapted either for duck- 
feet or chisel teeth. The price of this implement is 11/. lis. 
The second prize for chisel harrows was awarded to Messrs. Sharman and 
Ladbury's oscillating diagonal harrows (No. 4358). — This is a strong serviceable 
implement, but the front of the tines being square instead of V-shaped, ap- 
peared to me objectionable, increasing the resistance of the soil. The teeth 
are 9 inches long beneath the frame, to which they are attached by square 
shoulders, tbe end being topped and nutted. The frame is 6 feet wide and 
carries 1^5 teeth ; the oscillating motion is very satisfactory ; the work done 
was excellent. Price, 61.
