<h3><i>The Sacrificial Altar</i></h3>
<p>"I am off the trail," Harkness admitted. "Towahg guided me before; I
wish he were here to do it now."</p>
<p>They had pushed on for another short day, Harkness leading, and Chet
bringing up the rear and casting frequent backward glances in a vain
effort to catch a glimpse of some other moving figure.</p>
<p>Smothered at times in a dense tangle of vegetation, where they sweated
and worked with aching muscles to tear a path; watching always for the
flaming, crimson buds on grotesque trees, whose limbs were waving,
undulating arms and from which came tendrils like the one that had
nearly ended Diane's life, they fought their way on.</p>
<p>They had seen the buds on that earlier trip; had seen the revolting
beauty of them—the fleshy lips that opened above a pool of death into
which those reaching arms would drop any living thing they touched. They
kept well out of reach when a splash of crimson against the white trees
flashed in warning.</p>
<p>Again they would traverse an open space, where outcropping rocks would
send Kreiss into transports of delight over their rich mineral contents.
But always their leader's eyes were turned toward a range of hills.</p>
<p>"It is beyond there," he assured them, "if only we can reach it."
Harkness pointed to a scar on a mountainside where a crystal outcrop in
a sheer face of rock sparkled brilliantly in the sunlight. "I remember
that—it isn't so very far—and we can look back down the valley from
there and see our ship."</p>
<p>"But we'll never make it to-night," said Chet; "it's a case of making
camp again."</p>
<p>They had gained an altitude of perhaps a thousand feet. No longer did
the jungle press so hard upon them. Even the single file that had been
their manner of marching could be abandoned, and Harkness drew Diane to
his side that he might lend her some of his own strength.</p>
<p>Again the soft contours of the rolling ground had been disturbed: a
landslide in some other century had sent a torrent of boulders from the
high slopes above. Harkness threaded his way among great masses of
granite to come at last to an opening where massive monoliths formed a
gateway.</p>
<hr style="width: 45%;" />
<p>It was an entrance to another valley. They did not need to enter, for
they could skirt it and continue toward the high pass in the hills. But
the gateway seemed inviting. Harkness took Diane's hand to help her
toward it; the others followed.</p>
<p>The fast sinking sun had buried itself behind a distant range, and long
shadows swept swiftly across the world, as if the oncoming night were
alive—as if it were rousing from the somnolence of its daytime sleep
and reaching out with black and clutching hands toward a fearful,
waiting world.</p>
<p>"No twilight here," Chet observed; "let's find a hide-out—a cave, by
choice—where we can guard the entrance and—"</p>
<p>A gasp from Diane checked him. "Oh!" she exclaimed. "It is not real!
<i>C'est impossible!</i>"</p>
<p>Chet had been busied with the matter of a secure footing; he looked up
now and took a step forward where Harkness and Diane stood motionless in
a gateway of stone. And he, too, stopped as if stunned by the weird
beauty of the scene.</p>
<p>A valley. Its length reached out before them to end some half mile away.
Sides that might once have sloped evenly seemed weathered to a series of
great steps, and an alternation of striations in black and white made a
banding that encircled the entire oval. Each step was dead-black stone,
each riser was snow-white marble; and the steps mounted up and up until
they resembled the sides of a great bowl. In the center, like an altar
for the worship of some wild, gargantuan god, was a stepped pyramid of
the same startling black and white. Banded like the walls, it rose to
half their height to finish in a capstone cut square and true.</p>
<p>An altar, perhaps; an arena, beyond a doubt, or so it seemed to Chet. He
was first to put the impression in words.</p>
<p>"A stadium!" he marvelled; "an arena for the games of the gods!"</p>
<p>"The gods," Diane breathed softly, "of a wild, lost world—" But Chet
held to another thought.</p>
<p>"Who—who built it?" he asked. "It's tremendous! There is nothing like
it on Earth!"</p>
<hr style="width: 45%;" />
<p>Only Kreiss seemed oblivious to the weird beauty of the spectacle. To
Professor Kreiss dolomite and black flint rock were dolomite and black
flint; interesting specimens—a peculiar arrangement—but nature must be
permitted her little vagaries.</p>
<p>"Who built it?" He repeated Chet's question and gave a short laugh
before answering in words. "The rains, Herr Bullard, and the winds of
ages past. Yes, yes! A most remarkable example of erosion—most
remarkable! I must return this way some time and give it my serious
attention."</p>
<p>Harkness had not spoken; he was shaking his head doubtfully at Kreiss'
words. "I am inclined to agree with Chet," he said slowly. "But who
could have built a gigantic work like this? Have there been former
civilisations here?"</p>
<p>He straightened up and shook himself free from the effects of the wild,
barbaric scene.</p>
<p>"And you needn't come back," he told Kreiss; "you can have a look now,
to-night, by moonlight. We can't go on. I think we'll be safest on that
big altar rock; nothing will get near us without our knowing."</p>
<p>Chet felt Diane Delacouer's hand on his arm; her other hand was gripping
at Harkness. The shiver that passed through her was plainly perceptible.
"I'm afraid," she confessed in a half-whisper; "there's something about
it: I do not like it. There is evil there—danger. We should not enter."</p>
<p>Walt Harkness gently patted the hand that trembled on his arm. "I don't
wonder that you are all shot to pieces," he assured her. "After last
night, you've a right to be. But I really believe this is the safest
spot we can find."</p>
<hr style="width: 45%;" />
<p>He stepped forward beyond the great stones that were like a gateway from
one wildly impossible world to another. A rock slide, it seemed, had
smoothed off the great steps from where they stood, for there was a
descending slope that gave easy footing. He took one step, and then
another, to show the girl how foolish were her fears; then he started
back. In the fading light something had flashed from the jungle they had
left. Across the rocky expanse it came, to bury itself in the loose soil
and rubble, not two paces in advance of the startled man. An arrow!—and
it stood quivering in silent warning on the path ahead.</p>
<p>Chet quietly unslung his bow where he had looped it over one shoulder,
but Harkness motioned him back. The pistol was in his hand, but after a
moment's hesitation he returned that to his belt. His voice was low and
tense.</p>
<p>"Listen," he said: "we're no match for them with our bows. They are
hidden; they could pick us off as we came. And I can't waste a single
detonite shell on them while they keep out of sight. We can't go back;
we must go ahead. We will all make a break for it and run as fast as we
can toward the big altar—the pyramid. From there we can stand them off
for a while. And we will go now and take them by surprise."</p>
<p>He seized Diane firmly by one arm and steadied her as they dashed down
the slope. Chet and the professor were close behind. Each spine must
have tingled in anticipation of a shower of arrows. Chet threw one hasty
look toward the rear; the air was clear; no slender shafts pursued them.
But from the cover of the jungle growth came a peculiar sound, almost
like a human in distress—a call like a moaning cry.</p>
<hr style="width: 45%;" />
<p>They slackened their breath-taking pace and approached the great pyramid
more slowly. As they drew near, the great steps took on their real size;
each block was taller even than Chet, and he had to reach above his head
to touch the edge of the stone.</p>
<p>They walked quickly about; found a place where the great blocks were
broken down, where the slope was littered with debris from the
disintegrating stone that had sifted down from above. They could climb
here; it was almost like a crudely formed set of more normally sized
steps. They made their way upward while Chet counted the courses of
stone. Six, then eight—ten—and here Harkness called a halt.</p>
<p>"This—will do," he gasped between labored breaths. "Safe enough here.
Chet, you and Kreiss—spread out—watch from all—sides."</p>
<p>The pilot was not as badly winded as Harkness who bad been helping
Diane. "Stay here," he told Harkness; "you too, Kreiss; make yourselves
comfortable. I will go on up to the top. The moon—or the Earth,
rather—will be up pretty soon; I can keep watch in all directions from
up there. We've got to get some sleep; can't let whoever it is that is
trailing us rob us of our rest or we'll soon be no good. I'll call you
after a while."</p>
<hr style="width: 45%;" />
<p>The great capstone projected beyond the blocks that supported it; that
much had been apparent from the ground. But Chet was amazed at the size
of the monolith when he stood at last on the broad step over which this
capstone projected like a roof.</p>
<p>The shadows were deep beneath, and Chet, knowing that he could never
draw himself to the top of the great slab whose under side he could
barely touch, knew also that he must watch from all sides. The shadowed
floor beneath the big stone made a shelter from any watchful eyes out
there in the night; here would be his beat as sentry. He walked slowly
to the side of the pyramid, then around toward the front.</p>
<p>It was the front to Chet because it faced the entrance, the rocky
gateway, where they had come in. He did not expect to find that side in
any way differing from the first. Each side was twenty paces in length;
Chet measured them carefully, astounded still at the size of the
structure.</p>
<p>"Carved by the winds and rains," he said, repeating the opinion of
Professor Kreiss. "Now, I wonder.... It seems too regular, too much as
if—" He paused in his thoughts as he reached the corner; waited to
stare watchfully out into the night; turned the corner, and, still in
shadow, moved on. "Too much as if nature had had some help!"</p>
<p>His meditation ended as abruptly as did his steady pacing: he was
checked in midstride, one foot outstretched, while he struggled for
balance and fought to keep from taking that forward step.</p>
<p>In the shelter of the capstone was a darker shadow; there was a
blackness there that could mean only the opening of a cave—a cavern,
whose regular outlines and square-cut portal dismissed for all time the
thought of a natural opening in the rock. But it was not this alone that
had brought the man up short in his stealthy stride: it had jolted him
as if he had walked head on into the great monolith itself. It was not
this but a flat platform before the cave, a raised stone surface some
two feet above the floor. And on it, pale and unreal in the first light
of the rising Earth was a naked, human form—a face that grimaced with
distorted features.</p>
<hr style="width: 45%;" />
<p>Chet had known the ape-men on that earlier visit: he knew that while
most of them were heavily covered with hair there were some who were
almost human in their hairlessness. The body before him was one of
these.</p>
<p>It lay limply across the stone platform, the listless head hanging
downward over one edge. It had high cheekbones, a retreating forehead,
glassy, staring eyes, and grinning teeth that projected from between
loose lips. And the evening wind stirred the black, stringy hair while
it touched lightly upon the ends of a short length of vine about the
ape-man's neck, where only the ends could be seen, for the rest of the
pliant vine was sunk deeply into the flesh of the neck. It had been the
instrument of death; the ape-man had been strangled.</p>
<p>Chet tore his fascinated eyes from the revolting features of that purple
face; he forced himself to look beyond at what else might be on this
sacrificial stone. And, as he saw the assortment of fruit that was there
on a green mat of leaves, the surprise was even greater than would have
followed a repetition of the first discovery.</p>
<p>A naked, murdered man!—and ripe fruit! What was the meaning of this?
Chet asked himself a score of questions and found the answer to none.
But one thing he knew now beyond a doubt: Herr Professor Kreiss had been
wrong. This was truly an altar for the performance of unknown and savage
rites, and the altar itself and the whole encircling arena had been
created by some intelligence. People—things—embodied intelligences of
some sort had carved these stones. Chet was oppressed by a feeling of
impending danger.</p>
<p>His thoughts came back sharply to the things on the stone: the absurdly
contrasting exhibits: a naked body and fruit! But were they so
different? he asked himself, and knew in the same instant that they were
not. They were one and the same; they differed only in kind. They were
both food!</p>
<hr style="width: 45%;" />
<p>From the darkness beyond came a shuffling of feet. From the black
passage someone was coming—drawing near to the portal—and coming
slowly, steadily through the dark. The pad of animal feet would have
been unnerving—or the stealthy footfalls of an approaching savage—but
this was neither; it was a scuffing, shuffling sound. The sweat stood
out in beads on Chet's forehead and a trickle of it reached his eyes. He
dashed it away with the back of his hand while he drew silently into the
shadow of the overhanging stone. He held his breath as he watched in the
darkness.</p>
<p>His pistol came noiselessly from his belt. Yet, how could he fire it? he
asked himself in a moment of frantic planning. Only seven cartridges
left!—they would need them all; and to fire now would bring more
enemies upon them. He returned the gun to his belt and stooped to weigh
a fragment of stone in his hand: this must serve him as a weapon.</p>
<p>The dragging footsteps were near, where the passage mouth loomed black.
The light of a distant Earth, struck slantingly across to leave this
face of the pyramid in half-darkness. From that far and peaceful world
the light poured floodingly down; it shone in under the projecting
capstone; it struck upon the raised altar and revealed in ghastliest
detail the gruesome offering there. And surely the strangest sight of
all that that Earth-light disclosed was when it shone golden upon a
black and hairy body of a beast that was half man, half ape. The
creature moved slowly forward, walking erect, with its furry arms
stretched gropingly ahead. In the full light it went shuffling on like
one who is blind or who walks in the dark, until it stopped before the
altar stone and stood rigidly waiting.</p>
<hr style="width: 45%;" />
<p>Waiting for what? Chet was making demands upon his reason that was
already taxed beyond its capacity. He heard nothing, and he knew with
entire certainty that there was no audible call, yet he sensed the
message at the instant the ape-man moved.</p>
<p>"Flesh!" said the message. "Bring flesh! Bring it now!"</p>
<p>And, with glazed, wide-open eyes which plainly saw, but could not
comprehend, the ape-thing stared at the altar-stone. It bent forward,
took the fresh-killed body by the throat, and slung it across one
shoulder as easily as a child might handle a doll; then it turned and
vanished once more into the waiting dark.</p>
<p>"God!" breathed Chet when the vision had passed. "God help us! What does
it mean?"</p>
<p>He took one backward step, then another, and made his way in silence
along the path he had come. He must get back to the others to tell them
of what he had seen; to help them to flee from this place of horror that
was more terrible for its qualities of the unknown.</p>
<hr style="width: 45%;" />
<p>He gave his companions the story in staccato sentences. "And the ape-man
was unconscious," he concluded; "he was an automaton only, directed by
another brain. I know it. I got that message, I tell you; it was radioed
by someone or by something—sent direct to that big ape's brain.</p>
<p>"Now let's get out of here. Diane had it right when she said that the
place was evil. But she didn't make it strong enough. It's foul with
evil! It's damned! Come on, I'm leaving now!"</p>
<p>Chet's whispered words were uttered with all the emphasis that horror
could instill. He knew that he spoke truth. But he could not know how
mistaken was his last positive assertion.</p>
<p>"I'm leaving now!" Chet had said, and how desperately he wanted to put
this place behind him only he himself could know. He took one step
toward the place where they could descend; then Harkness' hand pulled
him roughly to his knees.</p>
<p>"Down!" Harkness was commanding; "get down, Chet! They're coming—a
swarm of them—through the gate!"</p>
<p>The pilot heard them before he saw them. They began a chant as they
poured through the entrance, a weird, wailing note like the cry of a
stricken animal that cries on and on. Then he saw the swarm.</p>
<p>They came in a cataract of black bodies that spilled through that stone
portal and down the long slope. They formed a ragged column on the
ground and came on toward the pyramid, where, unseen, three men and a
girl from another world were crouching.</p>
<p>"Back!" Chet ordered in a whisper. "Keep low—in the shadow! Get around
in back of the pyramid. We can make a run for it!"</p>
<hr style="width: 45%;" />
<p>They crept swiftly along the rocky step where the deep angle was in
shadow. They reached the rear slope where Chet had climbed. And each one
knew without the speaking of a word that retreat was not to be
considered. The open arena!—the high bank of great steps in their bold
markings of black and white! They could never hope to scale them; they
would never even reach them alive, for the savage horde would overwhelm
them before they had crossed the Earth-lit ground.</p>
<p>"All right," said Chet in acceptance of their unspoken thoughts, "up it
is! Here's a hand, Diane—up you go! Now watch your step, and climb as
if a thousand devils were after you, for there's all of that!"</p>
<p>The wave of bodies was washing against the pyramid's base when Chet drew
Kreiss, the last of the four, into the shadow of the huge capstone. The
noise of their climbing had been covered by the wailing cry that came
piercing shrilly from the throng far below. And they had been unseen,
Chet was sure; unless the one furtive shadow that he had seen draw away
from the crowd and slip around toward the rear of the pyramid meant that
some one of the tribe had found their trail.</p>
<p>From the front of the shadowed top came the shuffling of heavy, dragging
feet on the stone. It was the same as before. Chet had held some vague
idea of fighting off the horde from the top of the steps, for here was
the only place where they could ascend. He had forgotten this other one
for the moment, and he realized in a single flashing instant that here
was a worse menace than the pack.</p>
<p>Only one, it was true, one ape-man who would be no match for them! But
Chet remembered those blind, staring eyes and the message that had come
to him. Those eyes had seen the horrible food upon the altar; some other
brain had seen it too. The ape-man was an instrument only; there was
some hidden horror in back of him, something that saw with his eyes,
something that must never see them, cowering and huddled in the shadow
of that great stone.</p>
<hr style="width: 45%;" />
<p>The shuffling was coming from the right; Chet clutched silently at the
others to draw them away and toward the left. They retreated to the
corner, turned it, and went on toward the front; then stopped in silent
waiting where the shadow ended. The front, where the altar stood, was in
the full glare of Earth.</p>
<p>For the moment they were safe, but what of the time when the ape-man
returned? He had descended to the ground; when he climbed back again
would he retrace his steps? Or would he come this side and trap them
here where the light of their own Earth made any forward step
impossible?</p>
<p>Below them the wailing ceased. Chet leaned forward to see the black
horde, silent and motionless. Approaching them was the "big ape" he had
seen at the altar. His hands were reaching blindly before him and he
moved as would a human when entranced.</p>
<p>He reached the huddled blacks; his groping hands hovered hesitantly
above a cowering, hairy form. Presently the ape-man passed on to the
next, and his hands rested on the creature's face. From the massed
figures there rose a moan, and Chet felt poignantly the animal misery of
it. Suddenly all emotion was transformed to startled attention. From the
slope at the rear had come the rattle of loose stones!</p>
<p>Far below, in plain view, was the one who had descended—Chet knew that
his eyes could never mistake that blind, groping figure—but from the
slope they could not see, from around the far edge of the pyramid, a
clicking stone sent a repeated warning.</p>
<p>Chet laid a hand on Harkness' arm. "Get set, Walt!" he warned. "Get
ready for trouble. There's something coming: it may come this way!"</p>
