and wall, is caused by a deposit of extravasated blood, 

 bruised blood, commonly speaking. 



The cause of this is an excessive tightness around 

 the coronet, the blood gets into the foot, but the small 

 veins become so congested that it cannot make its 

 round of circulation, as it were, and get out again; it 

 is therefore the bursting of these small veins that 

 causes their contents to trickle down and lodge in tlie 

 lowest point of the foot at the place where tlie dis- 

 coloration makes its appearance. The small veins can 

 be, and are, occasionally broken with the same con- 

 sequence, discoloration of the sole, by the foot being 

 too broad and weak, though such cases are so rare as 

 to scarcely need attention, but will be explained 

 however. 



Explanation. 



There is no discomfort to the animal at the 

 point where this deposit is made apparent, and 

 there is, therefore, nothing gained by cutting away 

 the sole there, and above all things, never, under any 

 circumstances, should any foreign substance be 

 injected into the foot after the foolish operation of 

 cutting away the sole has been resorted to, as is too 

 often done. The author has seen a temporary relief 

 given to the animal by cutting a piece out of the wall 

 at the point opposite to where appears this discolora- 

 tion, so that the wall at that point has no bearing on 

 the shoe. But as mentioned, this is only a temporary 

 relief. The way to relieve this foot of its tightened 

 condition at the coronet is to put it into proper pro- 

 portion, which will be explained, so that the bones of 

 the foot, that have been crowded up out of their 

 proper resting place, can be let down, as it were, into 

 the foot, wliere they properly belong, instead of being 

 crowded up into the coronet. The author has seen 

 horses that came to the shop lame, from so-called 

 corns, go sound before they had gotten a quarter of a 

 mile from the shop, by relieving the coronet as sug- 

 gested, without doing anything else to the foot, or 

 placing upon it anything but a plain shoe. For some 

 insight into the manner of treating a foot so afflicted, 

 see direction under No. 14.
