NOTE.
I have, in another part of this work, spoken of the mule as being free from splint. Perhaps I should have said that I had never seen one that had it, notwithstanding the number I have had to do with. There are, I know, persons who assert that they have seen mules that had it. I ought to mention here, also, by way of correction, that there is another ailment the mule does not have in common with the horse, and that is quarter-crack. The same cause that keeps them from having quarter-crack preserves them from splint--the want of front action.
A great many persons insist that a mule has no marrow in the bones of his legs. This is a very singular error. The bone of the mule's leg has a cavity, and is as well filled with marrow as the horse's. It also varies in just the same proportion as in the horse's leg. The feet of some mules, however, will crack and split, but in most cases it is the result of bad shoeing. It at times occurs from a lack of moisture to the foot; and is seen among mules used in cities, where there are no facilities for driving them into running water every day, to soften the feet and keep them moist.
