"262 SAND-CRACK. 



pain; or a portion of the sensible part beneath has 

 protruded between the sides of the crack, and it is 

 there pressed and confined. The crack must now be 

 searched to the bottom. The sides must be pared 

 down ; and then, the fissure being freely open, the 

 sprouting granulations must be excised, and a poultice 

 must be applied to soothe the irritation and bring 

 away any sand which may have got into the crack. 

 When the dirt or gravel has been removed, and the 

 imprisoned laminse been liberated; a small piece of 

 tow, dipped in the weaker solution of chloride of zinc, 

 must be introduced into the 'crack and bound firmly 

 upon it ; while a bar shoe, with no bearing upon the 

 seat of injury, but a clip on either side of the crack, is 

 placed upon the foot. 



Unless the crack is very slight, the horse should be 

 rested for several weeks. If the fissure extend from 

 the top to the bottom of the crust, a stimulating lini- 

 ment or mild blister should be applied to the coronet, 

 to quicken the downward growth of horn. As soon 

 as there is sufficient new horn above the crack, one or 

 two transverse lines should be drawn with the firing- 

 iron upon it; so as to cut off the communication 

 with the diseased horn : a little melted tar and pitch 

 covered with tow may then be applied to it, and a 

 strap buckled tightly round the hoof. A bar-shoe of 

 the description before mentioned should be put on; 

 and then if the horse is much wanted he may go to 

 very gentle work; but six or eight months' additional 

 rest would be required to insure the sound growth of 

 the new hoof, or to renovate the secretive powers of 

 an exhausted nature.
