“There she is now,” cried Nimbus. “Come, let us be off!” “Please,” said Billy, who was intensely excited, “may I go, too? I should dearly love to help catch him.” “Why, yes, I guess so,” said Nimbus. “I’ll enchant the trolley car again and we’ll all go in that.” The trolley car had been very badly damaged by the Equine Ox, but Nimbus merely tapped it with his wand and it became whole again. The motorman regarded him open-mouthed. “Wouldn’t he be a wonder in a repair shop?” he exclaimed. “I guess she’ll hold together now,” said Nimbus. “Come on, Jack Frost; come on, Billy,” and he led the way into the car. The conductor and the motorman took their places, and the Equine Ox at the last moment crowded into the rear door. There was scarcely room for him, but Nimbus did not care to lose any time in putting him out. The car was speedily got under way and soon was merrily sailing along in the direction of the North Pole. [Illustration: “The Equine Ox crowded into the rear door”] WHERE NIGHT IS SIX MONTHS LONG CHAPTER X WHERE NIGHT IS SIX MONTHS LONG “It is a good thing that both the Evening Star and the Equator shine,” said Billy. “We can find them so easily in the dark.” “But there isn’t going to be any dark,” said Jack Frost. “Oh, but there will be at night!” said Billy confidently. “It is always dark at night. It has to be or you wouldn’t know it was night.” “But there won’t be any night for six months where we are going,” said Jack Frost. “There never is at the North Pole.” “Gracious!” said Billy; “that must be dreadful. And do the days last for six months, too?” “To be sure they do. If you ask a boy to come to your house to spend the afternoon at the North Pole he stays for three months.” “It must be terrible when the baby has the colic all night,” said Billy thoughtfully. “That happens often at our house, and Papa has to walk the floor with him.” “I don’t know much about babies,” said Jack Frost, “but I suppose they would stop crying before morning. Maybe they’d be satisfied crying for a month or two if they weren’t interrupted.” “There’s an iceberg,” said Nimbus, who had been keeping a lookout. “We ought to be getting there in a little while now. We are running into a dawn anyway.” To the southward Billy noticed a faint grayish streak in the sky, and soon he could see the white caps that the breakers always wear to keep their heads warm on windy days. They were going very fast. Little white specks that seemed to be flying past beneath them he now saw were icebergs, and by-and-by these began to appear in great numbers, dotting the sea like schools of tiny islands in all directions. Although the light was growing brighter all the time, he was still aware of a faint flickering glow to the northward, and this his friends told him was Aurora Borealis flashing the news that the Equator and the Evening Star were still in the neighborhood.
