“Ah, then it is you I have to thank,” said Uncle Wiggily to the sheep, with a low, polite bow. “You have done me a great favor. Perhaps, some day, I may be able to do you one.”

“Pray do not mention it,” said the sheep, also politely.

Then Uncle Wiggily mended his airship, sailed on to the store in it, and bought the things Nurse Jane wanted. On his way home, as he was flying over a green field, he heard a sad voice down below crying:

“Oh, my little lamb is lost! Oh, where can he be! Oh, isn’t this too bad!”

“Ha! That is my friend, the sheep lady, on whose wool I fell,” said Uncle Wiggily. “Now is my chance to do her a favor.”

Down he went in his airship, and he asked:

“What has happened, Mrs. Sheep? You seem to be in trouble.”

“I am in trouble,” sadly answered the mamma sheep. “My little lamb baby has strayed away, and is lost, I fear. Oh, I am so sorry!”

“Never fear!” said Uncle Wiggily, bravely. “I will go look for your little lost lamb in my airship. You were kind to me, and I am only too glad to be kind to you.”

“That is very good of you,” said the mamma sheep.
