Mark twisted his head around, saw Janus' huge frame struggling to move. He was a powerfully-built man, he'd be the one to do it if anyone did. Slowly, minutes at a time, he managed to drag one leg under him and then the other. He brought his hands into position. Sweat broke on his brow as he rolled himself over on all fours. Then with a terrific effort he hoisted himself erect! He stood there, a straddle-legged, red-bearded giant. But only for a second. His legs buckled. He managed to hurl himself toward the starboard port, as he slid downward. "At least I can see out now," he gasped. "We just did reach the twilight strip. There's a whole forest of great big green things, thirty feet high. Sort of like cactus, flat and spiny." "They must have helped break our fall!" "You said it! I can see a strip for over a mile, where we mowed 'em down. Hey! Look! For the love of--" Janus' voice dwindled off in amazement. "Damn it, man, how can we look? What is it? What's out there?" "People! Dozens of 'em! They're coming out of the forest. Oh--oh, they've spotted us. But they're not coming over. They just stand there jabbering and pointing." "People on this world," Brownell muttered his amazement. "What are they like, Janus? Describe them!" "They look kind of savage to me. Squat and furry, but they stand erect. Their legs are thick and heavy like an elephant's." "Yes, that would be natural on this world. The terrific gravity." "Gravity doesn't seem to bother them," Janus went on. "Let's see, now. Yes, in all other ways they seem to be low-evolutionary humans, except ... good Lord!" "Except what? Damn it, Janus, go on!" "They have knobs!" "What?" "Knobs! Growing right out of their foreheads. And they're lit up--the knobs, I mean. Sort of a soft white light." "Another logical development of nature," said the Professor. "They live on the dark side, so their bodies manufacture the necessary light. Are they armed?" "They are. Just crude spears and clubs, though, so I guess we're safe enough in here. Oh, oh, here they come. I think they see me!" Twisting his head around, Mark could barely see a corner of the window where Janus lay. In the twilight gray beyond he glimpsed the horde of barbarians rushing at the ship. It seemed fantastic that they could move in such gravity, fantastic that any creature could walk. One of them hurled a spear with deadly accuracy. It struck the window and glanced away. Others crowded around, pounding at the glass with clubs, clamoring to get at Janus who lay just beyond. "Professor," Janus said wryly, "this isn't very pleasant. Are you sure that glass will hold?" "Don't worry. It will take more than their pounding to crack four inches of crystyte."
