Report on the Exhihition of Implements 
Derhy, to be turned up a steep bank adjoininG^ the road. The 
horse was then encouraoed to descend by the voice of his driver, 
having never before felt the breaks. After a slight hesitation, 
and a few experimental steps, the animal seemed to acknowledge 
his power of holding the load, and came down the bank as steadily 
as if he were drawing on a level. Coaches have also been fitted 
with this simple apparatus, and the Judges understand that the 
strangest horse unhesitatingly avails himself of it, and regulates 
his resisting force with remarkable delicacy, according to the 
greater or less degree of the declivity. 
Cart Whecla and Tires. — Several manufacturers exhibited sets 
of wheels and axles, for one of which, by Mr. Crosskill, of 
Beverley, the silver medal was awarded, as combining good work- 
manship with cheapness. 
The Judges have also to commend the 4^ inch ridged tires 
applied by Mr. George Coates, of Richmond, Yorkshire, to some 
well-made carts exhibited by him. These were rolled in a piece, 
and made an excellent job. 
Harness and Gearing. — With respect to harness no improve- 
ment of moment was brought to the observation of the Judges. 
Under the head of gearing, which includes the methods of 
connecting or coupling animals with the objects to be put in mo- 
tion, Messrs. Ransome produced some new patent iron-trussed 
vvhippletrees, remarkable for their simplicity, strength, and durable 
properties. For this invention the silver medal was adjudged. 
The following figures will at once convey a clear idea of the 
structure of these whippletrees, which are altogether composed of 
light wrought-iron. Fig. 1 exhibits them as connected for a pair 
of horses ; fig. 2 shows the truss in the centre ; and fig. 3 is a 
section through the centre, to a scale of half the full size, repre- 
senting the form and substance of the bows or stretchers, which 
are welded together at the extremities, leaving an eye for a ring 
or hook. By this arrangement immense strength is derived from 
light materials, and many delays and accidents, which attend the 
fracture of the wooden articles in general use, will be avoided by 
employing these metallic dragging-bars.
