THRUSH.
This is another trouble with which the mule is afflicted. Cut away the parts of the frog that seem to be destroyed, clean the parts well with castile-soap, and apply muriatic acid. If you have not this at hand, a little tar mixed with salt, and placed on oakum or tow, and applied, will do nearly as well. Apply this every day, keeping the parts well dressed, and the feet according to directions in shoeing, and the trouble will soon disappear.
