138 INTERFERING. 



so fitted there will be no pressure on the part. To do this 

 a bar shoe will often be necessary. (See cut No. 22.) The 

 shoe should be re-set frequently until cured. 



QUARTER CHACK. 



When the hoof is dry and hard it is easily split. A piece 

 of glue when very dry splits and breaks very easily if 

 pounded upon, but if softened by moisture would only bend 

 and be bruised. The hoof partakes of the character of glue. 

 If very dry the fibres become dense and hard. If while the 

 feet are in this condition the horse is driven fast on hard 

 roads, the hoof is liable to burst. If the- hoof is thin and 

 contracted, there is great danger of the inside quarters 

 splitting. 



Cut down the hoof back of the crack, so that there is no 

 pressure of that part of the bearing surface upon the shoe, 

 put on a bar shoe, cut across the split deeply at the edge 

 of the hair with a firing iron. Next cut down the edges of 

 the hoof so far as split extends, to the quick. Then soften 

 and grow down the hoof rapidly by applying any good, 

 stimulating ointment. A mixture of equal portions of tar, 

 lard and turpentine, is excellent for this purpose. The 

 fitting of the shoe should be carefully attended to, the hoof 

 grown down as rapidly as it is safe to do, and the part kept 

 clean by covering it with a little tar, or a mixture of resin 

 and tallow. There will not be a cure until a new hoof is 

 grown down, which will take about six or eight months. 



INTERFUSING. 



Some horses 'travel so close that the least neglect of hav- 

 ing the shoe well under the quarter, and the part nicely 

 dressed down, would cause a bruising and cutting of the 



opposite ankle. The shoe 

 A should be so formed and 

 fitted as to come well under 

 the hoof. To do this well, 

 that side of the shoe should 

 be made rather straight, 

 (No. 23.) with the web narrow, and
