"What are you doing there?"
"Do you not see," said Brother Donkey, "that I am weighing myself? I want to see if the part of my body in front is as heavy as the part that is behind."
Brother Donkey, after great effort, at last succeeded in getting over the wall. Mr. Lion then said to his companion:
"Powerful King of Donkeydom, my esteemed friend! I believe that you are making sport of me. I believe that your strength, at its best, is no greater than that of a child."
"Do you have such a thought as that?" said Brother Donkey, with a smile. "You make a serious mistake, great King of Beasts. Let us make a trial of strength right here. Let us see which of us is able to destroy that great wall. The one that is victorious will be known as the king of the animals."
"This is a good idea," exclaimed Mr. Lion, heartily, "and I accept your conditions with pleasure."
Immediately Mr. Lion made an effort to show his power. He struck the wall with his paws, and then with his tail. He struck it on the right and on the left, but he only wounded himself. He did not succeed in making one stone fall. At the end of a quarter of an hour he gave up in despair.
"I cannot make an impression on this strong wall," said Mr. Lion. "Let us see if you will be more fortunate."
At once Brother Donkey began to bray and kick, and he used his heels with such effect that in a few minutes the wall was knocked down and destroyed.
