 which gave the horse a grip of the ground. 



Certainly, for a short time this was the case. 

 But the inventor had forgotten the rapidity with 

 which an iron shoe is ground down by friction upon 

 a hard road, and the result was, that the projections 

 soon wore away, and the Goodenough shoe became 

 just as smooth and slippery as any of the shoes which 

 it was intended to supersede. 



It had its period of popularity, but has long 

 ago passed into the Hmbo of shoes which have been 

 tried and found wanting. 



Then came a time when the expansive power of 

 the hoof was brought prominently forward, not to 

 say exaggerated. It was recognised that the exist- 

 ing shoes, being unyielding in their structure, pre- 

 vented the incessant expansion and contraction on 

 which the health of the hoof largely depends, and so 

 a number of shoes were devised which should permit

 three of them. 



The first is the Clark jointed shoe, to which a

This shoe is formed of two parts, each occupying
