Bearing-suiface 



lar care should be taken not to cut so much at any part as to cause 



bleeding. On this 

 account the op- 

 erator should feel 

 his way cautious- 

 ly, cutting deeper 

 as he goes back. 

 The bar should 

 be cut away to 

 within three quar- 

 ters of an inch 

 from the point of 

 the heel. No more 

 should be cut 

 away from the 

 rest of the bar, or 

 part coming un- 

 der the clip, than 



may be necessary to give a straight shoulder for it to rest against. 



Both sides must be treated alike. If the part has been cut through 



in the least, it should be protected after the shoe is on by melting 



a little resin and tallow 



into it, and covering 



with tow. 



There have been 



many ignorant and 



pretentious quacks, 



who have presumed to 



weaken the heel by 



sawing in between the 



bars and frog. Only a 



very small point can be 



reached in this way, 



without cutting to the quick. The saw cannot be used here at all 



with advantage. The point is to weaken the horn at the bottom 



of the cleft so that it will spread freely, and this can be done prop- 

 erly only with the cutting-knife. The proper flexibility of the 



heels can be judged by a slight pressure with the hand. 



This done, our next object is to remove the compression of the 



wall. To do this, fit to it a rather thin, flat shoe, made of good iron. 



At the neels it should be made a little wider and longer than the
