136 HORSE AND MAN. 



A little art is required in attaching this shoe. 

 Round the edge of the hoof a groove is cut, and into 

 the groove the shoe is sunk. The groove should be 

 fully as deep as the thickness of the shoe, and even 

 should it be a little deeper no harm will be done. 

 There is no difficulty in cutting the groove, as in all 

 places where the Charlier shoe is sold a special knife 

 is supplied. v This knife is a variation of the ordinary 

 draw-knife, and is furnished with a moveable guide 

 by which the dimensions of the groove are regulated. 

 The guide can be set to any point, and fastened by a 

 screw, so that even the most careless operator can 

 hardly make a mistake. 



As the shoe is flush with the horn, there is no 

 leverage, and in consequence it only requires a few 

 nails, and those of small size. The chief virtue of 

 the Charlier shoe, however, consists in the fact that, 

 as the horse steps, the horn and iron are worn away 

 simultaneously, so that the shoe can be worn down 

 until it is hardly thicker than a visiting card. 



It is not very easy to induce farriers to fix the 

 Charlier shoe to the hoof. All artisans have a 

 tendency to move in ruts, and are almost helpless 

 when taken out of them, and the farrier is perhaps 

 more wedded to his accustomed rut than any other 

 workman. 



Should the full, or three-quarter, Charlier be
