 of steel, quite thin and light, that the 

 horse may have his foot as near the

 the benefit of strong frog pressure. 

 The effect of a shoe with such a ground-

 horse upon an incline, as though as- 

 cending a hill, and, when in a stand-

 keep its place in its articulation with 

 the fetlock joint, and when in motion, 

 the foot will be able to slide over with-
