139. THE MOUSE AND THE BULL
A Bull gave chase to a Mouse which had bitten him in the nose: but the Mouse was too quick for him and slipped into a hole in a wall. The Bull charged furiously into the wall again and again until he was tired out, and sank down on the ground exhausted with his efforts. When all was quiet, the Mouse darted out and bit him again. Beside himself with rage he started to his feet, but by that time the Mouse was back in his hole again, and he could do nothing but bellow and fume in helpless anger. Presently he heard a shrill little voice say from inside the wall, "You big fellows don't always have it your own way, you see: sometimes we little ones come off best."
The battle is not always to the strong.
