"No, I will not let you go," roared the lion.
"Please do," cried the frightened mouse. "If you will let me go perhaps I can do something for you sometime."
This made the lion laugh. "You do something for ME," he said. "What a joke! Well, you are such a little fellow that I will let you go this time, but never let me see you about here again," and he lifted his paw.
As the little mouse scampered off, he said, "Thank you, kind lion, I shall not forget your kindness."
Some time after this the lion was caught in a trap. The hunters tied him to a tree while they went to get a wagon to carry him away.
The lion roared so loud that the ground shook. The little mouse heard him.
"That lion is in trouble," he said. "I will see what I can do to help him," and he ran to the lion.
When the mouse saw that the lion was tied with ropes, he said, "Cheer up, Mr. Lion. Be quiet and I will set you free," and he began gnawing the ropes.
He worked long and hard and at last the lion was free.
