SCIENTIFIC HORSESHOEING. 



For a foot affected in this manner, pare the hoof level and 

 aa low as possible, rasp the wall thin from coronet to ground 

 surface, and get the hoof back near as may be to its natural 

 shape. If there is any tenderness in the sole it must be protected 

 by using a plain, flat, broad-webbed shoe, well concaved on the 

 sole-bearing surface, the nail holes to be punched where the foot 

 is least affected, and the shoes reset every two or three weeks. 

 It is difficult to describe any particular style of shoe to meet the 

 emergencies of such cases, and the farrier must judge what is 

 best. Cold water bandages around the coronet will assist in 

 keeping the horn moist and allaying fever and pain. 



Fig. 40 illustrates 

 '^ the further ravages 



of chronic laminitis, 

 in which its destruc- 

 tive effects (coupled 

 with the mismanage- 

 ment of the foot) are 

 perhaps more plainly 

 discernible. In this 

 instance the heels 

 have been allowed to 

 grow to such an ex- 

 tent as to raise them 

 far above their nor- 

 mal position. The 

 normal angle of the 

 heel from the ground 

 surface to the coronet is the same as the angle of the front part of 

 the foot from toe to coronet. In proportion, however, as the 

 toe lengthens, just so much will the angle of the ground surface 

 of the foot be carried forward, as seen in the above diagram, 

 which shows the growth at the back of the quarters to be of 

 unusual height, raising the heels up out of their natural angle,
