LAMENESS AND DISEASES, ETC.

the coronary band, crowding the cartilages in and stopping in 

 a measure the circulation. The foot become dry, hard and 

 feverish and the wall thick and deep. The white line across the 

 heel shows where the foot should be reduced around the base. 

 When the disease becomes well established, the horse manifests 

 it by continual restlessness, standing on one foot and holding 

 the other backward, with heel elevated and toe touching the 

 ground, or by twisting the toe out and resting the heels of one 

 on the coronet of the other; and by constantly shifting and 

 flexing the fetlock and knee. 



iN'ot one-third of the cases of navicular disease which have 

 come under my observation are chronic ; and, indeed, many cases 

 which are thus wrongly termed should be considered only nav- 

 icular joint lameness, which if allowed to run might become 

 chronic, but are curable if taken in time. 



In dressing the foot 

 for the shoe, proceed as 

 per Fig. 23, then, after 

 properly leveling and bal- 

 ancing it, open up the 

 commissures and pare out 

 the sole within safe limits. 

 If the frog projects above 

 the heel, pare it flat on the 

 ground tread. In most 

 instances the bar shoe 

 shown in Fig. 63 can be 

 used with satisfactory re- 

 sults. It can be easily 

 made, being of the same 

 thickness in both branches 

 from the heel to the cen- 

 ter of the quarters; in front of the quarters it is gradually 

 thinned, and at the toe it is rolled or beveled, as indicated at B.
