There were many pools of water in the plain; and once the men were compelled to deviate from their course by a narrow, winding lake. The aspect of the resilient ooze was indepictably monotonous and was unrelieved by any vegetable growth or outcropping of mineral. But somehow it was not dead, but conveyed a sense of somnolent vitality, as if it possessed a dark, secret life of its own.

The vapors parted in the oblique rays of the sun. Not far ahead, Roverton and Deming now perceived a low, table-like elevation. Even at first sight, it suggested an island; and as the men neared it the characteristics it revealed were indicative that it really had been such, and that the plain around it had been the bed of a shallow sea at no very ancient date. There were wave-marks in the soil about the base; and, in contradistinction to the utter barrenness of the plain, there were boulders and tree-forms on its long undulating sides; and several ruinous walls and monoliths of an unearthly architecture were visible on the broad, flat summit.

“Now for some Andromedan archaeology,” Roverton commented, pointing to the ruins.

“Not to mention some more botany,” added Deming.

Both of them peered with considerable caution and trepidation at the foremost trees and plants. These were similar in type to the monstrosities of the jungle; but they were more sparse and scattered; and somehow there was a difference. When Deming and Roverton approached them the nature of the difference became manifest. The ophidian branches drooped and trailed on the ground, and were strangely still and unmoving. Seen closer at hand, they were withered and mummified.    It was evident that the trees had long been dead.

Not without repulsion, Roverton broke off the end of one of the hanging tentacles. It snapped easily; and he found that he could crumble it into fine powder between his fingers. Realizing that there was nothing to be feared, he and Deming began to climb the slope toward the fantastic ruins.

The soil of the hill, a sort of grey and purple marl, was firm beneath their feet. They reached the summit as the sinking sun began to disappear behind a far-off line of cliffs that rose like the core of a continent from the plain.

Circled about with rows of the dead plant-monsters, there stood in the center of the summit the strange ruins that Roverton and Deming had descried from below. They gleamed in the light with a dull luster, and appeared to be made of some foreign stone that was heavily impregnated with metal. They were apparently the remnants of several immense buildings, and bore the marks of some awful cataclysm that had carried away their super-structures and even much of the floor-work and foundations. One of the walls retained a doorway that was oddly high and narrow and was wider at top than at bottom. Also, there were some queer windows close to the ground. The men wondered at the physical characteristics of the race that had reared such edifices. From a human standpoint everything about the ruins was architecturally abnormal.

Roverton approached one of the monoliths. It was square in shape, was forty feet high by seven in diameter, and had manifestly been taller at one time, for the top was riven and jagged where it had been broken off abruptly. It was wrought of the same material as the walls. A series of bas-reliefs, intermingled with columns of hieroglyphic letter-forms, had been carven about the base. The bas-reliefs depicted beings of a curious type, with long thin trunks terminating at each end in a multitude of many-jointed limbs. The heads of these creatures, or what appeared to be such, were at the nether extremity of the trunks, and had two mouths that were set above a double row of eyes. Ear-like appendages drooped from the chins. The lower limbs ended in bird-like claws and the upper in broad, umbrella-shaped webs whose use was beyond conjecture. Roverton exclaimed with amazement as he called Deming’s attention to these figures. Whether such beings represented an extinct race, or whether their prototypes were still to be found in this outré world, was of course an irresolvable problem.

The men were too worn out with their herculean ordeals to devote much time and energy to speculation of this order. They found a sheltered place in the angle of one of the walls, and sat down. Perforce they had eaten nothing since the food provided by the pygmies at early dawn; and seemingly there was no immediate likelihood of finding anything edible.    The whole outlook was supremely desolate and desperate.

VII

The sun had gone down, leaving an erubescent twilight that stained the soil, the ruins and the dead trees as with a deepening tide of blood. A preternatural silence prevailed—a silence fraught with the sense of foreign mystery, the burden of ultramundane antiquity that clung to those strange ruins. The men lay down and began to doze.

They awoke simultaneously, without knowing for a brief moment what it was that had aroused them. The twilight had turned to a rich violet, though the walls and trees were still clearly distinguishable. Somewhere in this twilight, there was a shrill, strident humming that grew louder momentarily.

All at once the humming was near at hand, in mid-air. It soared to a deafening clamor. Roverton and Deming saw that a swarm of giant insects with curving five-inch bills were hovering about them as if uncertain whether or not to attack. There seemed to be hundreds of these formidable-looking creatures. One of them, bolder than the others, darted forward and stung Deming on the back of his left hand till its beak almost protruded from his palm. He cried out with the pain, and struck the insect with his other fist. It squashed beneath the blow and fell to the ground, emitting a nauseous stench.

Roverton sprang to his feet and broke off a bough from one of the trees. This he waved at the swarm, which retreated a little but did not disperse. An idea came to him, and he thrust the bough into Deming’s hand, saying:

“If you can keep them off, I’ll try to build a fire.”

While Deming waved his ineffectual weapon at the hesitating army, Roverton broke off more of the dead, tentacle-like boughs, piled them, and crushed others into a heap of fine dust with his heel. Then, in the twilight, he found two small fragments of the metallic stone from which the buildings had been wrought; and striking the fragments together, he obtained a spark which fell into the dust-pile and ignited it. The stuff was highly combustible, for in less than a minute the heap of boughs was burning brightly. Terrified by the blaze, the insects fell back; and their stridulation soon diminished and sank away in the distance.

Deming’s hand was now painfully swollen and throbbing from the sting he had received.

“Those brutes would have finished us if they had been nervy enough to attack in force,” he observed.

Roverton piled more fuel on the fire, in case the swarm should return.

“Christ! What a world!” he ejaculated. “I wish Volmar were here, confound him!”

As he spoke, there was a far-off droning in the crepuscular sky. For a moment, the men thought that the insect swarm was coming back to assail them again. Then the droning deepened to a great roar. The roar was somehow familiar, though neither could determine at first the memory which it tended to evoke. Then, where stars were beginning to pierce the vague heavens, they saw the indistinct bulk that descended toward them.

“My God! Is that the space-flier?” cried Deming.

With a final roaring and screeching of its propellers, the bulk came to rest within fifty feet of the fire. The light flickered on its metal sides and revealed the well-known ladder down which the three mutineers had climbed in an alien darkness.

A figure descended the ladder and came toward the fire. It was Captain Volmar. His face was drawn and livid in the firelight, and looked older than the two men remembered it. He greeted them stiffly, with an odd trace of embarrassment in his manner.
