one mistake may cause irreparable injury. To be definite, we can safely give extra 

 frog and heel pressure in all cases where the hoof is deep at the quarters, where there 

 is a tendency toward contraction and atrophy of the frog, where the obliquity of the 

 pastern is not too 

 great, and where the 

 feet and limbs are per- 

 fectly sound and well 

 proportioned. (This lat- 

 ter will narrow the 

 circle more than most 

 people are aware of.) 

 No thoughtful man 

 would dare to throw 

 extra weight on the 

 sole and frog of a foot 

 that had long suffered 

 with navicular disease, 

 however excellent this 

 would be as a pre- 

 ventive. Neither 



should we throw extra weight on the posterior parts of a foot or limb where there 

 is any soreness of flexor muscles or tendons, or any ligament involved, as it would 

 entail greater tension on the parts, while the opposite is what is required, viz., flex- 

 ion or relaxation. 



I say distinctly, we should only carry frog-pressure to the extent of bringing into 

 activity all the elastic structures of the foot, which increases the circulation of those 



parts so liable to atrophy, and 

 only tlirough the circulation can we 

 keep up or restore the health, 

 vigor, and growth of frog, sole, 

 heels, and quarters of the horse's 

 foot. 



Prof. McLellan says :— 



In reference to the use of tips, 

 I give you only an outline. They 

 are useful in the case of corns, 

 in quarter-cracks, in thrush, in 

 interfering, and in fitting the 

 horse to run at grass. They are 

 not applicable to feet that have 

 thin, flat soles, with low heels. 

 They are not applicable to heavy 

 work horses with flat feet and 

 prominent frogs (such frogs are 

 liable to suffer bruises when so 

 exposed, the resulting inflam- 

 mation extending frequently to deeper and more vital structures). They are not ap- 

 plicable to feet having navicular disease. They are not applicable when, in apply- 

 ing them, it is necessary to disturb the normal relation of the bones of the limb.
