134 HORSE AND MAN.

 walking, the nails become more and more bent, and 

 their points are liable to penetrate the linea alba, an 

 accident which often results in lockjaw. In Mayhew's 

 well-known work on ' Horse Management,' p. 83, 

 there is a very good figure of the mischief which 

 may be wrought by a loosened shoe. 



Even granting that no such accident happen, and

 is kept off the ground, and so cannot be subject to 

 the friction which is necessary for its benefit. It

 as it ouovht to be. 



Now, granting for the sake of argument that the 

 horse must have a shoe, it is evident that the best shoe
