bone will perform its functions, and the horse 

 will have a brand neW' foot, or rather a brand 

 new case on the old, bruised and much abused 

 foot. Keep the springs in for three months, 

 but remove them and look after the bottom of 

 the foot at least every two wxeks. 



The same treatment in modified form can be 

 used in severe cases of contraction where the 

 trouble is chiefly from the middle of the quar- 

 ters back to the heels, and on cases that would 

 not be classed as "hoof bound." The main 

 groove in this case extends from the heel to 

 about the middle of the quarter, on each side 

 of the foot, the front part of the wall not being 

 touched. The operation will give immediate 

 relief and the horse can be put to work as soon 

 as the soreness caused by the blister subsides. 

 This operation is known as the "Dunbar sys- 

 tem," and was first introduced and its merits 

 demonstrated to the horseshoers of the East 

 many years ago b}^ Professor Daniel L. Cor- 

 bin, of Friendship, N. Y., a famous horseshoer 

 in his day, who spent the best years of his life 

 in the interest of the horse, by studying the 

 anatomy of the foot and leg and inventing 

 special shoes for his relief and for the correc- 

 tion of faulty action. Professor Corbin is still 

 living (1916) enjoying the fruits of his diligent 

 and commendable work. 



I wish to add that this "scoring," as it is 

 called, is an excellent way in which to bring 

 out one quarter that has "fallen in," or where 

 the foot is only contracted on one side. The 

 scoring is done on the affected side, and the 

 force of the spring, by reason of a clip at the
