 shoe ; that the sole be made smooth, by taking 

 away the dry and crumbly dead horn, which 

 renders its surface irregular, but that none of the 

 tough or solid horn be removed ; keeping always 

 in mind, that it is better for the foot to leave a

 but that none of the tough and living substance 

 be taken away.
