And, later on, Sister did get the mumps, but I'm glad to say her brother did not hold a lemon up in front of her. For, as I told you, even the thought of anything sour hurts the mumps.

Now you know the reason why I didn't want you to read this story when you had the swelling in your neck. It was better to wait until your mumps were gone; wasn't it?

So this boy had the mumps, and he had them on both sides at once, which is the very worst form. He could hardly swallow anything because of the pain, even things that were not sour. Now and then he managed to sip a little hot chocolate.

His mother put a warm flannel bandage around his face, which was much swelled, and, thus wrapped up, the little boy could, now and then, get out of bed.

It was on one of these times, when his jaws were wrapped up, and his face swollen, that Uncle Wiggily happened to hop along through the woods, not far from the Mump Boy's house. And, having very good eyes, Mr. Longears saw the sick lad.

"Poor fellow!" thought the bunny gentleman. "He is ill, just as he thought he was going to be! Toothache it is, too!"

"Who has the toothache!" asked Dr. Possum, for the animal doctor came along just then, with his bag of medicine held fast in the curl of his tail.

"That boy," answered Uncle Wiggily, pointing from the bush, where he and Dr. Possum were hiding, to the window of the boy's home.

"He hasn't the toothache! Those are the mumps!" said Dr. Possum, who knew all about such things.

"Mumps!" exclaimed Uncle Wiggily. "Oh, that's too bad. Why, if that boy is mumpy he must have trouble eating. I wonder if I could leave on his doorstep something he would like—something that he wouldn't have to chew and which would slip down easily?"
