"I wish I could be one," he said wistfully, after a moment's silence. "It must be awfully nice to have everything you want." Jimmieboy thought so, too, but he was too much interested in getting to Saturn to say anything, so he, too, kept silent and pedalled away as hard as he could. Together and happily they went on until Jimmieboy said:-- "Bikey, what's that ahead? Looks like the side of a great gold cheese." "That," Bikey answered, "is exactly what you think it is. It's the ring of Saturn, and, as the saying goes, for biking Saturn is quite the cheese. In two minutes we'll be there." And in two minutes they were there. In less, in fact, for hardly eight seconds had passed before a great, blinding light caused Jimmieboy to close his eyes, and when he had opened them again he and Bikey were speeding along a most beautiful road, paved with gold. "I thought so," said Bikey, "we're on the ring. And isn't it smooth?" "It's like riding on glass," said Jimmieboy. And then they stopped short. A peculiar looking creature had stopped them. It was a creature with a face not unlike that of a man, and a body like a man's, but instead of legs it had wheels like a bicycle. If you can imagine a Centaur with a body like a bicycle instead of a horse you will have a perfect mental picture of this strange creature. "Excuse me," said the stranger, "but we have to be very particular here. Where do you come from?" "Earth," said Bikey. "All right," said the stranger. "Move on, I'm a Saturn policeman and so many wheelmen from the Sun and the Moon and Jupiter have caused disturbances of late that we have had to forbid them coming. You are the only Earth people who have been here, and of course are not included in our rules, but I will have to go along with you to see that you do not break any of them." "We're very glad to meet you," said Bikey, "and if you'll tell us your rules we will be very glad to obey them." "Well," said the creature with wheels instead of legs, "the first rule is that nobody shall ride a wheel standing on his head. There was a person over here from Mars last week who actually put his head in the saddle and wheeled his pedals with his hands." "How utterly absurd!" said Jimmieboy.
