thing to prevent it, after the heels grow high enough to 

 lose their frog pressure. I used a pair of heavy heel-weight 

 bar shoes, about ten or eleven ounce, on one yearling's hind 

 feet to stop forging and scalping while he was being jogged 

 every day. The shoes he was brushed or speeded in for 

 about ten days did not suit him for jogging. This yearling 

 trotted eighths in 17 J4 seconds, a 2:18 gait. I tried more 



weight in front but it did no good. 



XLVI. SLIPPING OR SLIDING TOO MUCH. 



Slipping will unbalance a horse when trying to get on 

 his stride at speed ; slipping too much on landing or on 

 leaving the ground creates lost action that cannot be over- 

 come by muscular development. I will cite a couple of 

 cases here to prove this. A horse that trotted in his work 

 miles in 2 :27 over a half-mile track, when shipped to Rigley, 

 Portland, Me., could not trot a mile there in 2:45 without 

 being very unsteady, and this over a mile track. I exam- 

 ined his foot prints and saw he was slipping too much. I 

 calked his shoes with toe and heel calks, never changed his 

 feet, and this horse trotted miles in 2:25 without a break. 



A mare that was trotting miles in her work over this 

 same half-mile track in 2:25 easily, quarters in 33 or 33^ 

 seconds, was shipped to Portland, Me., to a mile track and 

 could not trot a mile there in 2 :40 without mixing and act- 

 ing very unsteady. On examining her foot prints I found 

 she was slipping too much. I was sure her feet were 

 fixed properly. As she became very unsteady and inclined 

 to mix, I added two ounces more to her front shoes and 

 gave her a heel and toe calk on hind and front shoes and 

 she became very steady the next workout, and the driver 

 told me she could trot a mile in 2:16 or better. 



After the drivers of those two horses found they would 

 get all unbalanced trying to get on their stride, they did not
