“Even a reasonably large piece of the lens will do, Don,” the voice came from the speaker. It was not Lackland’s voice; he was an expert teacher, he had found, but sometimes yielded the microphone to a specialist. “Any piece will bend the light, and even make an image—but wait; that comes later. Try to find what’s left of that hunk of glass, Don, if your gravity didn’t powder it when the set landed.” Dondragmer turned from the set with a word of agreement; then turned back as he thought of another point.
“Perhaps you could tell what this ‘glass’ is made of, and whether it takes very much heat? We have good hot fires, you know. Also there is the material set over the Bowl—ice, I think Charles called it. Would that do?”
“Yes, I know about your fires, though I’m darned if I see how you do burn plants in a hydrogen atmosphere, even with a little meat thrown in. For the rest, ice should certainly do, if you can find any. I don’t know what the sand of your river is made of, but you can try melting it in one of your hottest fires and see what comes out. I certainly don’t guarantee anything, though; I simply say that on Earth and the rest of the worlds I know ordinary sand will make a sort of glass, which is greatly improved with other ingredients. I’m darned if I can see eithers how to describe those ingredients to you or suggest where they might be found, though.”
“Thank you; I will have someone try the fire. In the meantime, I will search for a piece of lens, though I fear the blow when it struck left little usable. We should not have tried to take the device apart near the edge of the mound; the thing you called a ‘barrel’ rolled much too easily.”
Once more the mate left the radio, and immediately encountered Barlennan.
“It’s about time for your watch to get on the plates,” the captain said. “I’m going down to the river. Is there anything your work needs?”
Dondragmer mentioned the suggestion about sand.
“You can carry up the little bit I’ll need, I should think, without getting the fire too hot; or did you plan on a full load of other things?”
“No plans; I’m taking the trip mainly for fun. Now that the spring wind has died out and we get breezes in every old direction, a little navigation practice might be useful. What good is a captain who can’t steer his ship?”
“Fair enough. Did the Flyers tell you what this deck of machines was for?”
“They did pretty well, but if I were really convinced about this space-bending business I’d have swallowed it more easily. They finished up with the old line about words not really being enough to describe it. What else beside words can you use, in the name of the Suns?”
“I’ve been wondering myself; I think it’s another aspect of this quantity-code they call mathematics. I like mechanics best myself; you can do something with it from the very beginning.” He waved an arm toward one of the carts and another toward the place where the differential pulley was lying.
“It would certainly seem so. We’ll have a lot to take home—and some, I guess, we’d better not be too hasty in spreading about.” He gestured at what he meant, and the mate agreed soberly. “Nothing to keep us from playing with it now, though.” The captain went his way, and Dondragmer looked after him with a mixture of seriousness and amusement. He rather wished that Reejaaren were around; he had never liked the islander, and perhaps now he would be a little less convinced that the Bree’s crew was composed exclusively of liars.
That sort of reflection was a waste of time, however. He had work to do. Pulling plates off the metal monster was less fun than being told how to do experiments, but his half of the bargain had to be fulfilled. He started up the mound, calling his watch after him.
Barlennan went on to the Bree. She was already prepared for the trip, two sailors aboard and her fire hot. The great expanse of shimmering, nearly transparent fabric amused him; like the mate, he was thinking of Reejaaren, though in this case it was of what the interpreter’s reaction would be if he saw the use to which his material was being put. Not possible to trust sewn seams, indeed! Barlennan’s own people knew a thing or two, even without friendly Flyers to tell them. He had patched sails with the stuff before they were ten thousand miles from the island where it had been obtained, and his seams had held even in front of the valley of wind.
He slipped through the opening in the rail, made sure it was secured behind him, and glanced into the fire pit, which was lined with metal foil from a condenser the Flyers had donated. All the cordage seemed sound and taut; he nodded to the crewmen. One heaped another few sticks on the glowing, flameless fire in the pit; the other released the moorings.
Gently, her forty-foot sphere of fabric bulging with hot air, the new Bree lifted from the plateau and drifted river-ward on the light breeze.
About the Author
Hal Clement, pen name of Henry Clement Stubbs, was born in 1922 in Somerville Massachusetts. Clement studied astronomy at Harvard University, graduating in 1943. After graduation, he joined the Army Air Corps reserve and flew combat missions with the 8th Air Force in World War II. He remained involved in the military for over thirty years. Clement also taught science for forty years in Boston-area high schools, an occupation which he credits with keeping his knowledge of scientific trends up to date. As readers of his novels know, real scientific knowledge forms the backbone of much of his work
Clement’s interest in science fiction began at an early age, and he published his first story in Astounding Science Fiction magazine at the age of twenty. In 1949, his first novel, the science fiction mystery Needle, was serialized in the same magazine. He followed it with perhaps his most well known work, 1953’s Mission of Gravity. Other works include Iceworld, Close to Critical, Star Light, Still River and Fossil.
