They soon discovered that the Saw-Horse limped, for his new leg was a trifle too long. So they were obliged to halt while the Tin Woodman chopped it down with his axe, after which the wooden steed paced along more comfortably. But the Saw-Horse was not entirely satisfied, even yet.

"It was a shame that I broke my other leg!" it growled.

"On the contrary," airily remarked the Woggle-Bug, who was walking alongside, "you should consider the accident most fortunate. For a horse is never of much use until he has been broken."

"I beg your pardon," said Tip, rather provoked, for he felt a warm interest in both the Saw-Horse and his man Jack; "but permit me to say that your joke is a poor one, and as old as it is poor."

"Still, it is a Joke," declared the Woggle-Bug; firmly, "and a Joke derived from a play upon words is considered among educated people to be eminently proper."

"What does that mean?" enquired the Pumpkinhead, stupidly.

"It means, my dear friend," explained the Woggle-Bug, "that our language contains many words having a double meaning; and that to pronounce a joke that allows both meanings of a certain word, proves the joker a person of culture and refinement, who has, moreover, a thorough command of the language."

"I don't believe that," said Tip, plainly; "anybody can make a pun."

"Not so," rejoined the Woggle-Bug, stiffly. "It requires education of a high order. Are you educated, young sir?"

"Not especially," admitted Tip.

"Then you cannot judge the matter. I myself am Thoroughly Educated, and I say that puns display genius. For instance, were I to ride upon this Saw-Horse, he would not only be an animal he would become an equipage. For he would then be a horse-and-buggy."

At this the Scarecrow gave a gasp and the Tin Woodman stopped short and looked reproachfully at the Woggle-Bug. At the same time the Saw-Horse loudly snorted his derision; and even the Pumpkinhead put up his hand to hide the smile which, because it was carved upon his face, he could not change to a frown.

But the Woggle-Bug strutted along as if he had made some brilliant remark, and the Scarecrow was obliged to say:

"I have heard, my dear friend, that a person can become over-educated; and although I have a high respect for brains, no matter how they may be arranged or classified, I begin to suspect that yours are slightly tangled. In any event, I must beg you to restrain your superior education while in our society."

"We are not very particular," added the Tin Woodman; "and we are exceedingly kind hearted. But if your superior culture gets leaky again—" He did not complete the sentence, but he twirled his gleaming axe so carelessly that the Woggle-Bug looked frightened, and shrank away to a safe distance.

The others marched on in silence, and the Highly Magnified one, after a period of deep thought, said in an humble voice:

"I will endeavor to restrain myself."

"That is all we can expect," returned the Scarecrow pleasantly; and good nature being thus happily restored to the party, they proceeded upon their way.

When they again stopped to allow Tip to rest—the boy being the only one that seemed to tire—the Tin Woodman noticed many small, round holes in the grassy meadow.

"This must be a village of the Field Mice," he said to the Scarecrow. "I wonder if my old friend, the Queen of the Mice, is in this neighborhood."

"If she is, she may be of great service to us," answered the Scarecrow, who was impressed by a sudden thought. "See if you can call her, my dear Nick."

So the Tin Woodman blew a shrill note upon a silver whistle that hung around his neck, and presently a tiny grey mouse popped from a near-by hole and advanced fearlessly toward them. For the Tin Woodman had once saved her life, and the Queen of the Field Mice knew he was to be trusted.

"Good day, your Majesty," said Nick, politely addressing the mouse; "I trust you are enjoying good health?"

"Thank you, I am quite well," answered the Queen, demurely, as she sat up and displayed the tiny golden crown upon her head. "Can I do anything to assist my old friends?"

"You can, indeed," replied the Scarecrow, eagerly. "Let me, I intreat you, take a dozen of your subjects with me to the Emerald City."

"Will they be injured in any way?" asked the Queen, doubtfully.

"I think not," replied the Scarecrow. "I will carry them hidden in the straw which stuffs my body, and when I give them the signal by unbuttoning my jacket, they have only to rush out and scamper home again as fast as they can. By doing this t............
