The thing looked bigger than ever as the jeep approached it, bumping across the muck of the freshly plowed field. From here he could see a faint line running around, just below the juncture of side and top. Major Greer hadn't mentioned that. The line was quite obvious; in fact, it was more of a crack. With a sound like a baseball smacking the catcher's glove, the crack opened, the upper half tilted, men sliding--then impossibly it stood open, vibrating, like the roof of a house suddenly lifted. The driver gunned the jeep. There were cries, and a ragged shrilling that set Straut's teeth on edge. The men were running back now, two of them dragging a third. Major Greer emerged from behind the object, looked about, ran toward General Straut shouting. "... a man dead. It snapped; we weren't expecting it...." Straut jumped out beside the men, who had stopped now and were looking back. The underside of the gaping lid was an iridescent black. The shrill noise sounded thinly across the field. Greer arrived, panting. "What happened?" Straut snapped. "I was ... checking over that thin spot, General. The first thing I knew it was ... coming up under me. I fell; Tate was at the other side. He held on and it snapped him loose, against a tree. His skull--" "What the devil's that racket?" "That's the sound we were getting from inside before, General. There's something in there, alive--" "All right, pull yourself together, Major. We're not unprepared. Bring your half-tracks into position. The tanks will be here soon." Straut glanced at the men standing about. He would show them what leadership meant. "You men keep back," he said. He puffed his cigar calmly as he walked toward the looming object. The noise stopped suddenly; that was a relief. There was a faint and curious odor in the air, something like chlorine ... or seaweed ... or iodine. There were no marks in the ground surrounding the thing. It had apparently dropped straight in to its present position. It was heavy, too--the soft soil was displaced in a mound a foot high all along the side. Behind him, Straut heard a yell. He whirled. The men were pointing; the jeep started up, churned toward him, wheels spinning. He looked up. Over the edge of the gray wall, six feet above his head, a great reddish limb, like the claw of a crab, moved, groping. Straut yanked the .45 from its holster, jacked the action and fired. Soft matter spattered, and the claw jerked back. The screeching started up again angrily, then was drowned in the engine roar as the jeep slid to a stop. Straut stooped, grabbed up a leaf to which a quivering lump adhered, jumped into the vehicle as it leaped forward; then a shock and they were going into a spin and.... * * * * * "Lucky it was soft ground," somebody said. And somebody else asked, "What about the driver?" Silence. Straut opened his eyes. "What ... about...."
