Cramp
I have now under my charge several mules that are subject to this
complaint. It does not really injure them for service, but it is very
disagreeable to those having them in charge. It frequently requires from
half an hour to two hours to get them rubbed so as the blood gets to its
proper circulation, and to get them to walk without dragging their legs.
In cases where they are attacked violently, they will appear to lose all
use of their legs. I have known cases when a sudden stroke with a light
piece of board, so as to cause a surprise, would drive it away. In other
cases sudden application of the whip would have the same effect.
