230 HOW TO SnOE A HOUSE. 



From the cc acave foot the horn may be removed, until 

 the sole will yield to a moderate pressure. From the flat 

 toot, little need be pared ; while the pumiced foot should 

 be depri ved of nothing but the ragged parts. 



The c: ist should be reduced to a perfect level all round, 

 but lett a little higher than the sole, or the sole will be 

 bruised by its pressure on the edge of the seating. 



The heels will require considerable attention. From 

 the stress which is thrown on the inner heel, and from the 

 weakness of the quarter there, the horn usually weaj'S 

 away considerably faster than it would on the outer one ; 

 and if an equal portion of horn were pared from it, it 

 would be left lower than the outer heel. The smith should 

 therefore accommodate his paring to the comparative wear 

 of the heels, and be exceedingly careful to leave them pre- 

 cisely level. 



Miles, after forcibly recommending that the frog (ex- 

 cept in very rare cases, of horses with unusually fast-grow- 

 ing frogs), should never be cut or pared; and giving 

 instances which have come under his own observation, and 

 which have demonstrated the truth of his theory, says: 



The first stroke of the knife removes this thin horny 

 covering altogether, and lays bare an under surface, totally 

 unfitted, from its moist, soft texture, for exposure either to 

 the hard ground or the action of the air ; and in conse- 

 quence of such unnatural exposure it soon becomes dry 

 and shrinks: then follow cracks, — the edges of which 

 turning outwards form rags ; these rags are removed by 

 the smith at the next shoeing, whereby another such siir 

 5icc is exposed, and another foundation laid for other 

 rags; and so on, until at last the protruding, plump, elastic 

 cushion, interposed by nature between the navicular joint 

 and the ground, and so essential to its j)reservation from, 

 isijury, is converted by the mischievous interference of art
