Up until that time, we had confined our activities to the area between the ship and the shore—a small enough space at best. Now we rounded the shining blunt bow of the Ertak and headed inland, Correy and myself in the lead, the two portable disintegrator ray-men immediately behind us, and the four other men of the party flanking the ray operators, two on each side.
It was hot, but the air was dry and invigorating. There was not a cloud visible in the sky. Far ahead was a low line of bluish, fronded, vegetation; whether small trees or some fern-like undergrowth, we could not determine. The ground between the ship and the line of vegetation was almost completely barren, the only growth being a lichenous sort of vegetation, gray-green in color.
Here and there on the ground were the imprints of sharp, split hoofs, and Correy pointed these out to me with the comment that one of the guards had reported seeing a number of slender-legged animals roaming here in the star-light, apparently seeking water, but frightened by the strange apparition of our ship.
"From the way he described them, they're something like the deer we used to have on Earth," he said. "I've seen the fossils in the museums, and they had little sharp, split hoofs like—"
One of the men behind us shouted a warning at that instant, and we both whirled in our tracks. My eyes fell instantly upon one of the strangest and most fearsome sights I have ever seen—and I have explored many strange and terrible worlds.
To our left, a huge circular section of the earth had lifted, and was swinging back on a hinge of glistening white fibers; a disk as great in diameter as the height of a man, and as thick as a man's body.
Where the disk had been, gaped a tunnel slanting down into the earth, and lined with the same glistening white fibers which covered the bottom of the disk, and hinged it in place. As I looked, there sprang from this tunnel a thing which I shall call a spider, yet which was too monstrous to be called by such an innocuous name.
It was rust red in color, with eight bristling legs, each tipped with three curved and tufted claws. On each side of its face was an armored mandible, tipped with shining fangs, and beside them, slender, six-jointed palps stretched hungrily.
The man who had seen the disk fly up opened fire without orders, and if he had not done so, some of us would not have returned to the ship. As it was, the atomic pistol whispered a steady stream of death which spattered the hairy body into an oozing pulp while it was still in mid-air. We leaped away, adding our fire to that of the alert guard who had first seen the apparition, and the spider, a twitching bundle of bespattered legs, fell on the spot where, an instant before, we had been.
