the above instructions are 

 carried out, the foot will be- 

 come straight and natural. 

 The dished foot shown 

 \^ on page 173 is a result of 

 overgrowth of the hoof. 

 The toe is lengthened and 

 the heel raised in such a way 

 as to throw the foot out of 

 its natural angle. This pro- 

 duces an unnatural pressure 



thus preventing the action 

 of the secretive powers ; 

 more or less inflammation 

 sets in and as the internal

It has been observed that if 

 the foot be allowed to remain in this condition for any length 

 of time, the upper pastern becomes enlarged, which to me is 

 conclusive proof that it has been overtaxed. 



Horses accustomed to slow work do not sufler from this as 

 much as road and track horses. When the heel and toe are al- 

 lowed to grow to an unusual height and length, the angle of the 

 heel with the ground line is carried forward under the leg, thus 

 causing the weight to be thrown out of the axis of the leg and 

 foot ; and when the horse is at full speed, the height of his heels 

 prevents the natural expansion of the foot, from heel to quarters, 

 at each foot fall, and he lands his foot upon the ground with a 

 dead jar, like that experienced by a man walking on a wooden 

 leg. This jar will not be transmitted through the axis of the 

 leg, pasterns and foot bone, as would be the case if the foot were
