"Look at those teeth!" Slaker whispered fiercely. "That's our monster." Immediately the head reacted, demonstrating acute hearing. It came forward rapidly, twenty feet above the ground; and in a moment the rest of the creature came into sight. The body was a globular mass about four feet across, mounted on a number of spindly legs. The creature walked with a peculiar caterpillar ripple, one ten-foot leg swinging around the body in a clockwise direction while the others were stationary, reminding Tinnerman of the problems of a wounded daddy-long-legs. The body spun, rotating with the legs; but the feet managed to make a kind of precessional progress. The spin did not appear to interfere with balance or orientation; the ring of eye-stalks kept all horizons covered. Slaker whipped out his sidearm. "No!" Tinnerman cried, too late. Slaker's shot smacked into the central body, making a small but visible puncture. * * * * * The creature halted as if non-plussed, legs rising and falling rhythmically in place. It did not fall. Slaker's second bullet tore into it, and his third, before Tinnerman wrested away the gun. "It wasn't attacking," he said, not knowing how to explain what he knew. They watched while the monster's motion gradually slowed, huge drops of ichor welling from its wounds. It shuddered; then the legs began pounding the ground in short, violent steps, several at a time. Coordination was gone; slowly the body over-balanced and toppled. The great mouth opened like a flower, like a horn, and emitted an earshattering blast of sound, a tormented cry of pain and confusion; then the body fell heavily on its side. For a moment the three men stood in silence, watching the death throes. The creature's legs writhed as though independently alive, and the head twisted savagely on the ground, knocking off the oddly brittle eye-stalks. Tinnerman's heart sank, for the killing had been pointless. If he had told the others his nighttime revelation-- From the forest came a blast of incredible volume. Tinnerman clapped both hands over his ears as the siren stridence deafened them with a power of twelve to fifteen bels. It ended, leaving a wake of silence. It had been a call, similar to that of the creature just shot, but deeper and much louder. There was a larger monster in the forest, answering the call for help. "Its mate?" Abel wondered out loud, his voice sounding thin. "Its mother!" Tinnerman said succinctly. "And I think we'd better hide." Slaker shrugged. "Bullets will stop it," he said. Tinnerman and Abel forged into the brush without comment. Slaker stood his ground confidently, aiming his weapon in the general direction of the approaching footfalls. Once more the fog-horn voice sounded, impossibly loud, forcing all three to cover their ears before drums shattered and brains turned to jelly. Slaker could be seen ahead, one arm wrapped around his head to protect both ears, the other waving the gun.
