Although the journey through the Tube was longer, this time, than before, it was so much more comfortable that none of our friends minded it at all. They talked together most of the time and as they found the dragon good-natured and fond of the sound of his own voice they soon became well acquainted with him and accepted him as a companion.
"You see," said Shaggy, in his frank way, "Quox is on our side, and therefore the dragon is a good fellow. If he happened to be an enemy, instead of a friend, I am sure I should dislike him very much, for his breath smells of brimstone, he is very conceited and he is so strong and fierce that he would prove a dangerous foe."
"Yes, indeed," returned Quox, who had listened to this speech with pleasure; "I suppose I am about as terrible as any living thing. I am glad you find me conceited, for that proves I know my good qualities. As for my breath smelling of brimstone, I really can't help it, and I once met a man whose breath smelled of onions, which I consider far worse."
"I don't," said Betsy; "I love onions.
"And I love brimstone," declared the dragon, "so don't let us quarrel over one another's peculiarities."
Saying this, he breathed a long breath and shot a flame fifty feet from his mouth. The brimstone made Betsy cough, but she remembered about the onions and said nothing.
They had no idea how far they had gone through the center of the earth, nor when to expect the trip to end. At one time the little girl remarked:
"I wonder when we'll reach the bottom of this hole. And isn't it funny, Shaggy Man, that what is the bottom to us now, was the top when we fell the other way?"
"What puzzles me," said Files, "is that we are able to fall both ways.
"That," announced Tik-Tok, "is because the world is round."
"Exactly," responded Shaggy. "The machinery in your head is in fine working order, Tik-Tok. You know, Betsy, that there is such a thing as the Attraction of Gravitation, which draws everything toward the center of the earth. That is why we fall out of bed, and why everything clings to the surface of the earth."
"Then why doesn't everyone go on down to the center of the earth?" inquired the little girl.
"I was afraid you were going to ask me that," replied Shaggy in a sad tone. "The reason, my dear, is that the earth is so solid that other solid things can't get through it. But when there's a hole, as there is in this case, we drop right down to the center of the world."
"Why don't we stop there?" asked Betsy.
"Because we go so fast that we acquire speed enough to carry us right up to the other end."
"I don't understand that, and it makes my head ache to try to figure it out," she said after some thought. "One thing draws us to the center and another thing pushes us away from it.
But--"
"Don't ask me why, please," interrupted the Shaggy Man. "If you can't understand it, let it go at that."
"Do you understand it?" she inquired.
"All the magic isn't in fairyland," he said gravely. "There's lots of magic in all Nature, and you may see it as well in the United States, where you and I once lived, as you can here."
"I never did," she replied.
"Because you were so used to it all that you didn't realize it was magic. Is anything more wonderful than to see a flower grow and blossom, or to get light out of the electricity in the air?
The cows that manufacture milk for us must have machinery fully as remarkable as that in Tik-Tok's copper body, and perhaps you've noticed that--"
And then, before Shaggy could finish his speech, the strong light of day suddenly broke upon them, grew brighter, and completely enveloped them. The dragon's claws no longer scraped against the metal Tube, for he shot into the open air a hundred feet or more and sailed so far away from the slanting hole that when he landed it was on the peak of a mountain and just over the entrance to the many underground caverns of the Nome King.
