It was too much for Billie. She felt that she could not contemplate the thing any longer with safety to her sanity. She exerted her will, and broke the connection with Mona; so that a few minutes later her three friends on the earth were listening to her account. The doctor waited until she was all through; then, "While you were having that experience I was in touch with young Ernol again. The boy has recovered and is still in jail, but they let him have his books now. And I've been helping him study geography." "Well?" eagerly. "Very simple. Capellete is a double world!" "Double!" "Yes! There are two globes, instead of one. They're twins, and Siamese twins at that!" He drew a figure on his knee, thus: [Illustration: two circles touching each other] "Just imagine the earth and Venus of the same size, and so near to one another that their combined gravity has brought them together! That's Capellette! And the contact is the place where they touch!" They considered this in wondering silence for a while. Then the doctor continued: "It's just as we had deduced; each of the planets is larger than the earth. I saw the figures in that geography. "But astronomically they are one. They revolve around Capella together; the rotate about a common center daily, just as the earth rotates on its axis. This common center is, of course, in the contact." "Are both globes inhabited?" Billie was greatly interested. "Yes. All parts of both planets are developed to the same extent, and evenly settled. They are just one great nation, with a common language. This, of course, is traceable to the great density of the air, enabling the people to fly wherever they wanted to go. There never has been such a thing as an 'Old World' and a 'New World' with them. "The really remarkable fact, however, Billie has already hinted at. The country near Mona's home shows no sign of industry; there's nothing but parks and magnificent estates. And the geography explains it all. One of the planets is devoted entirely to industry and the homes of those who are engaged therein; the workers inhabit that globe exclusively. There are about ten billion of them. "The other globe is exclusively a residence tract, set aside for the homes of the rich; what they call the owners. There is no industry of any kind. No workers live there, excepting the army of servants and park attendants which the owners need for their own comfort. The population is about a hundred million, of which only one in ten is a capitalist. The rest are serving people." Van Emmon seemed to feel that it was his place to comment. "In other words, Newport on a grand scale!" "Is that the way Powart seems to regard it?" from Billie. "Apparently. There were a lot of things in his talk which I couldn't understand until now; but it's clear enough--the doctor's right."
