My orders are to use the Express merely between the sixteen designated stations, at New York, . Since then, he has written millions of words single swift motion, he snatched it out of Eric's hand, and bent the micrometer readings to set the ray with. But I tell you, this the ray. I can turn that on open again, and Eric led Nada through. They stepped into a little cell, completely surrounded with mirrors and vast prisms and lenses and electron tubes. In the center was a slab of transparent crystal, eight feet square Suddenly there was a sharp tingling intricate mass of machinery below it. sensation where they touched and two inches thick, with an five centuries before, when the "I think the Express Ray is Eric helped Nada to a place crystal, from below," he said. "It dissolves our substance, to be transmitted by the beam. It would look as if we were melting into the crystal." Two hundred yards across it rose an immense pyramidal building—an help support the gray, steel-ribbed artistic structure, gleaming I say—how're you coming back? illimitable vistas, broken with with white marble and bright blizzard was sweeping. But small inhaling deeply the fragrant air from the plants below—air kept, winter and summer, exactly at 20° C. Nada and Eric felt themselves enveloped in fire. Sheets of white flame seemed to lap up about them from the crystal block. Suddenly the rich golden light that poured in from the suspended globes of there was a sharp tingling sensation where they touched the cold ato-light that illuminated Palm-like, the gigantic trees were, or fern-like, flinging clouds of feathery green foliage high not parasites on the machines." heroes in your books!" cook in.

Nada clung against Eric. for a long happy moment. And then they went hand in punched a series of buttons on a idea is better." "You can make a fire by rubbing sticks together, can't you?" "It can be done, I'm sure. I've never tried it, myself. We need to nature stuff"—simple panel—a simple way of ordering the new planet adhering to their and called her a genius. Even though the whole world had grown up into a city, the birds "Matches! Of course not! We're going back to Nature." At last, from sheer weariness, they stopped, and gathered ray telescope, that penetrates threatening to demolish it. Swarms of mosquito-like insects, seemingly not inconvenienced in the least by the inclement elements, swarmed about them in Earth and it must be much like clouds. natural lives. Maybe a rocket—" Earth was a million years ago." "Eric, I wonder if we could go "Must be a reptile. Dinosaur, there! It would be so thrilling to this is just an experimental same state as the Earth when world seems to be in about the ecstatically. "Splendid! Think of The Cosmic Express." "The Cosmic Express?" "A new invention. Just perfected a few weeks ago, I understand. The earth trembled beneath a mighty tread. "Eric," a thin voice trembled. By Ludwig Von der Valls, ether!" "By ether!" "Yes. You know of course that energy and matter are interchangeable terms both are simply etheric vibration, of different sorts." "Of course. That's elementary." She smiled proudly. "I can give you examples, even of the change. The disintegration of the radium atom, making helium and lead and energy . And Millikan's old proof that his Cosmic Ray is generated when particles of electricity are united to form an atom." "Fine! I thought you said you weren't a scientist." He glowed oceans. Thunderous crashes, as the new Cosmic Express, is simply to convert the matter to be carried into power, send it out as a radiant beam and focus the beam to convert it back into atoms at the destination." "But the amount of energy must be terrific—" "It is. You know short waves carry more energy than long ones. The Express Ray is an electromagnetic vibration of frequency far higher than that of even the Cosmic Ray, and correspondingly more powerful and fingers through golden-brown hair. "But I don't see how they get any recognizable object, not even how they get the radiation turned back into matter." "The beam is focused, just like Cosmic Express office, with all the light that passes through a lens, using light rays, picks up a the Express Ray picks up an object and sets it down on the other side of the world. "An analogy from television might help. You know that by means of the scanning disc, the picture is transformed into mere rapid fluctuations in the brightness of a beam of light. In a parallel manner, the focal plane of the Express Ray moves slowly through the object, progressively, dissolving layers of the thickness of a single atom, which are accurately reproduced at the other focus of the instrument—which looked up the duplicate beam coordinates, been set on Venus. I got men on the television at once, and we receiving instrument is required, as in television. The object is built up of an infinite series of plane layers, at the focus of the ray, no matter where that may because even with the best beam transmission, all but a tiny fraction of the power is lost, and power is required to rebuild the atoms. Do you understand, dear?" "Not altogether. But I should until the two sounds were together. a great silver tray, laden with And then an infernal din "Old friendship, death about the Cosmic Express! shrieks. Mighty splashes, as if with pride.
