SHOEING 



The horse's foot is particularly liable to disease both from the 

 delicacy of its mechanism, and the injury to which it is exposed. The 

 feet of the stabled horse bear eloquent testimony to the class of man- 

 agement which is in vogue. Cleanliness is an all-important feature. 

 Under the influence of manure and urine the horn of the foot is very 

 liable to suffer, the urine acts chemically by its alkaline nature, in 

 which horn is more or less soluble. This corrosive action is particu- 

 larly evident in the matter of the sole and frog, especially the latter, 

 where in conjunction with wet and filth, inflammatory trouble is set 

 up in the sweat glands of the frog, with destruction of horn and loss 

 of function.
