“They’re shouting for you,” she said with a smile.

“But I could never have done it,” he objected, “without everyone else’s help.”

“That may be true,” said Reason gravely, “but you had the courage to try; and what you cando is often simply a matter of what you willdo.”

“That’s why,” said Azaz, “there was one very important thing about your quest that we couldn’t discuss until you returned.”

“I remember,” said Milo eagerly. “Tell me now.”

“It was impossible,” said the king, looking at the Mathemagician.

“Completely impossible,” said the Mathemagician, looking at the king.

“Do you mean——” stammered the bug, who suddenly felt a bit faint.

“Yes, indeed,” they repeated together; “but if we’d told you then, you might not have gone—and, as you’ve discovered, so many things are possible just as long as you don’t know they’re impossible.”

And for the remainder of the ride, Milo didn’t utter a sound.

Finally, when they’d reached a broad, flat plain midway between Dictionopolis and Digitopolis, somewhat to the right of the Valley of Sound and a little to the left of the Forest of Sight, the long line of carriages and horsemen stopped, and the great carnival began.

Gaily striped tents and pavilions sprang up everywhere as the workmen scurried about like ants. Within minutes there were racecourses and grandstands, side shows and refreshment booths, gaming fields, Ferris wheels, banners, bunting, and bedlam, almost without pause.

The Mathemagician provided a continuous display of brilliant fireworks made up of exploding numbers which multiplied and divided with breathtaking results—the colors, of course, being supplied by Chroma and the noise by a deliriously happy Dr. Dischord. Thanks to the Soundkeeper, there was music and laughter and, for very brief moments, even a little silence.

Alec Bings set up an enormous telescope and invited everyone to see the other side of the moon, and the Humbug wandered through the crowd accepting congratulations and recounting in great detail his brave exploits, most of which gained immeasurably in the telling.

And each evening, just at sunset, a royal banquet was held. There was everything imaginable to eat. King Azaz had ordered a special supply of delicious words in all flavors and, for those who liked exotic foods, in all languages, too. The Mathemagician had provided innumerable platters of division dumplings, which Milo was very careful to avoid, for, no matter how many you ate, when you finished there was more on your plate than when you began.

And, of course, following the meal came songs, epic poems, and speeches in praise of the princesses and the three gallant adventurers who had rescued them. King Azaz and the Mathemagician pledged that every year at this same time they would lead their armies to the Mountains of Ignorance until not one demon remained, and everyone agreed that no finer carnival for no finer reason had ever been held in Wisdom.

But even things as fine as all that must end sometime, and late on the afternoon of the third day the tents were struck, the pavilions were folded, and everything was packed ready to leave.

“It’s time to go now,” said Reason, “for there is much to do.” And, as she spoke, Milo suddenly remembered his home. He wanted very much to go back, yet somehow he could not bear the thought of leaving.

“And so you must say good-by,” said Rhyme, patting him gently on the cheek.

“To everyone?” said Milo unhappily. He looked around slowly at all the friends he’d made, and he looked very hard so as not to forget any of them for even an instant. But mostly he looked at Tock and the Humbug, with whom he had shared so much—the perils, the dangers, the fears, and, best of all, the victory. Never had anyone had two more steadfast companions.

“Can’t you both come with me?” he asked, knowing the answer as he said it.

“I’m afraid not, old man,” replied the bug. “I’d like to, but I’ve arranged a lecture tour which will keep me occupied for years.”

“And they do need a watchdog here,” barked Tock sadly.

Milo embraced the bug who, in his most typical fashion, was heard to mumble gruffly, “BAH,” but whose damp eyes told quite a different story. Then the boy threw his arms around Tock’s neck and, for just a moment, held on very tightly.

“Thank you for everything you’ve taught me,” said Milo to everybody as a tear rolled down his cheek.

“And thank you for what you’ve taught us,” said the king—and, as he clapped his hands, the little car was brought forward, polished like new.

Milo got in and, with one last look, started down the road, with everyone waving him on.

“Good-by,” he shouted. “Good-by. I’ll be back.”

“Good-by,” shouted Azaz. “Always remember the importance of words.”

“And numbers,” added the Mathemagician forcefully.

“Surely you don’t think numbers are as important as words?” he heard Azaz shout from the distance.

“Is that so?” replied the Mathemagician a little more faintly. “Why, if——”

“Oh dear,” thought Milo; “I do hope they don’t start it all again.” And in a moment they had faded from sight as the road dipped, turned, and headed for home.

As the pleasant countryside flashed by and the wind whistled a tune on the windshield, it suddenly occurred to Milo that he must have been gone for several weeks.

“I do hope that no one’s been worried,” he thought, urging the car on faster. “I’ve never been away this long before.”

The late-afternoon sun had turned now from a vivid yellow to a warm lazy orange, and it seemed almost as tired as he was. The road raced ahead in a series of gentle curves that began to look familiar, and off in the distance the solitary tollbooth appeared, a welcome sight indeed. In a few minutes he reached the end of his journey, deposited his coin, and drove through. And, almost before realizing it, he was sitting in the middle of his own room again.

“It’s only six o’clock,” he observed with a yawn, and then, in a moment, he made an even more interesting discovery.

“And it’s still today! I’ve been gone for only an hour!” he cried in amazement, for he’d certainly never realized how much he could do in so short a time.

Milo was much too tired to talk and almost too tired for dinner, so, without a murmur, he went off to bed as soon as he could. He pulled the covers around him, took a last look at his room—which somehow seemed very different than he’d remembered—and then drifted into a deep and welcome sleep.

School went very quickly the next day, but not quickly enough, for Milo’s head was full of plans and his eyes could see nothing but the tollbooth and what lay beyond. He waited impatiently for the end of class, and when the time finally came, his feet raced his thoughts all the way back to the house.

“Another trip! Another trip! I’ll leave right away. They’ll all be so glad to see me, and I’ll——”

He stopped abruptly at the door of his room, for, where the tollbooth had been just the night before, there was now nothing at all. He searched frantically throughout the apartment, but it had vanished just as mysteriously as it had come—and in its place was another bright-blue envelope, which was addressed simply: “FOR MILO, WHO NOW KNOWS THE WAY.”

He opened it quickly and read:

Dear Milo,

You have now completed your trip, courtesy of the Phantom Tollbooth. We trust that everything has been satisfactory, and hope you understand why we had to come and collect it. You see, there are so many other boys and girls waiting to use it, too.

It’s true that there are many lands you’ve still to visit (some of which are not even on the map) and wonderful things to see (that no one has yet imagined), but we’re quite sure that if you really want to, you’ll find a way to reach them all by yourself.
