DISEASES OF HORSES AND CATTLE. 265 



on a level bar shoe. When the shoe is fitted rasp 

 away a little of the wall at the seat of the corn, 

 so that the shoe will not press on it. By thus re- 

 moving the inflammation by the poultice, and the 

 bar shoe taking the weight off the sore part, the 

 animal will go sound. The corn should never be 

 pared, and no strong medicine, such as spirits of 

 salt, applied to it, as it does harm and is unneces- 

 sary. In some cases by removing the shoe, which 

 is causing the corn, and putting on a bar shoe, 

 removing the pressure from the part, the horse 

 will go sound without having to be laid off work. 

 If matter forms it will be necessary to make a 

 small opening to allow the matter to escape, then 

 put on a poultice for a few days, then put on a 

 bar shoe as above. Put a little tar and oakum in 

 the opening to keep out the dirt until a new piece 

 of sole grows up. The bar shoe should be used un- 

 til the sole of the foot grows strong. Then by using 

 the flat shoe and not paring the sole you will not be 

 troubled with any more corns on your horse's feet. 

 Thousands of dollars are lost yearly from corns 

 alone caused by bad shoeing. 



Thrush. — This is a disease characterized by a 

 foetid discharge from the frog, caused by a dis- 

 eased condition of the secretory surface of the 

 fatty frog. The clefts are the parts usually af- 

 fected, and if the disease is not properly treated 

 it will soon spread over the whole frog, causing a 

 detachment of the horny part from the sensitive. 



Causes: Anything that interferes with the 

 health of the part, notably bad shoeing, by pre-
