129. THE LION AND THE ASS
A Lion and an Ass set up as partners and went a-hunting together. In course of time they came to a cave in which there were a number of wild goats. The Lion took up his stand at the mouth of the cave, and waited for them to come out; while the Ass went inside and brayed for all he was worth in order to frighten them out into the open. The Lion struck them down one by one as they appeared; and when the cave was empty the Ass came out and said, "Well, I scared them pretty well, didn't I?" "I should think you did," said the Lion: "why, if I hadn't known you were an Ass, I should have turned and run myself."
