W
hat hit us?" he demanded when Smithy got to him. "Did I crash?" He looked about him with dazed eyes from which he never would have seen again, but for the protection of his goggles.
"Fire," said Smithy tersely. "They did it, the devils, and it wasn't a flame-thrower, either. There wasn't a flash of their cursed green light. It just flicked us for a second. You got the worst of it. Your half roll saved us. That thing, whatever it was, would have ripped our left wing off in a second."
He was looking at the forward cockpit where the metal fuselage was melted. The leather cushioning around the edge was black and charred. Culver's helmet had protected him, but half of his face was seared as if it had been struck by a white flame.
"But we got some of them: they know we can hit back...." Smithy began, but knew he was speaking to deaf ears. Again his passenger had lapsed into unconsciousness.
Quickly he disconnected their own radio receiver and threw on the emergency radio siren. Ahead of them for a hundred miles an invisible beam was carrying the discordant blast. Then, with throttle open full, regardless of levels and of air traffic that tore frenziedly from his path, he drove straight for the home field.
I
n the office of the Governor, the radio newscaster was announcing last-minute items of interest. The Governor switched off the instrument as Smithy entered, supporting the tall figure of Colonel Culver, whose face and head were swathed in bandages. Culver had insisted upon accompanying him for the rendering of their report, though Smithy had to do the talking for both of them.
He outlined their experience in brief sentences. "And now," he was saying grimly, "you can go as far as you please, Governor. You've got a man's sized fight on your hands. We don't know how many there are of them. We don't know how fast they'll spread out, but—"
A shrill wail interrupted him. From the newscasting instrument came a flash of red that filled the room. The crystal, the emergency call, installed on all radios within the past year and never yet used, was clamoring for the country's attention.
Governor Drake sprang to switch it on, and tried to explain to Smithy as he did so. "It's out of my hands now," he said. "Washington has—" Then the radio came on with a voice which shouted:
"Emergency order. All aircraft take notice. Mole-men"—Smithy started at the sound of the word; it was the name he had given them himself—"Mole-men are invading Western states. A new race. They have come from within the earth. In Arizona, three ships of the Transcontinental Day Line, Southern Division, have been destroyed with the loss of all passengers and crew. Shattered in air.
"It is war, war with an unknown race. Goldfield, Nevada, is in ruins. Heavy loss of life. Federal Government taking control. Air-Control Board orders traffic to avoid following areas...."
There followed a list of locations, while still the red crystal blazed its warning across the land and to all aircraft in the skies. Southern California, Arizona, Nevada—Southern Transcontinental Routes closed; all except military aircraft grounded in restricted areas.
S
mithy's excitement had left him. In his mind he was looking far off, deep under the surface of the world. "They've been there," he said quietly, "thousands of years. A new race—and they've just now learned of this other world outside. Three ships downed! They picked them off in the air just as they tried to do with us. I knew we had a fight on our hands."
His voice died to silence in the room where now the new announcer was giving a list of the dead—a room where men were speechless before an emergency no man could have foreseen. But Smithy's eyes, gazing far off, saw nothing of that room. Again he was seated on an outthrust point of rock, Dean Rawson beside him, and from the black depths beneath a man's voice was rising clearly, mockingly it seemed, in song:
"You're pokin' through the crust of hellAnd braggin' too damn loud of it,For, when you get to hell, you'll findThe devil there to pay!"
"You're pokin' through the crust of hellAnd braggin' too damn loud of it,For, when you get to hell, you'll findThe devil there to pay!"
"The devil is there to pay," Smithy repeated softly. He leaned across and placed one hand on Colonel Culver's knee. "With your assistance, Colonel, I'd like to go down there and find him. You and I, we know the way—we'll organize an expedition. Maybe we can settle that debt."
B
efore a barrier of gold, waist-high, Dean Rawson stood tense and rigid. Behind him the great cave-room swarmed with warriors, leaders, doubtless, of the unholy hordes. But beyond the barrier were the real leaders of the Mole-men tribes—Phee-e-al, ruler in chief, and his clustering guard of high priests. In the flooding light from the wall, their eyes were circles of dead-white skin. A black speck glinted wickedly in the center of each.
Phee-e-al was speaking. His artificially whitened face grimaced hideously; the shrill whistling voice made no comprehensible sound. But in some manner Rawson gathered a dim realization of what his gestures meant.
Phee-e-al pointed at the captive; and one lean hand, with talons more suggestive of a bird of prey than of a human hand, pointed downward. "Gevarro," he said. The word was repeated many times in the course of his whistling talk.
"Gevarro"—what did it mean? Then Rawson remembered. It was the word he had heard in his dreams, the name of the lake of fire.
The voices of the priests rose in a shrill chorus of protests, and even Phee-e-al stood silent. They crowded about their ruler, and Rawson knew they were demanding him for themselves. Then the one who still held a human body in his arms sprang forward and his long talons worked unspeakable mutilation upon the body and face.
Rawson averted his eyes from the ghastly spectacle. For, swiftly, he was seeing something more horrifying than this desecration of a dead body; he was seeing himself, still living, tortured and torn by those same beastly hands. The dead face of Sheriff Downer was staring at him from red, eyeless sockets as with one leap Rawson threw himself over the golden wall. Ten leaping strides away was his gun. In that instant of realization, he knew why his life had been spared.
In the room of fire he had destroyed their priest. They had saved him for further torture.
T
o get his hands on the gun, to die fighting—the thought was an unspoken prayer in his mind. Behind him the room echoed with demoniac shrieks. Before him was the metal stand. His outstretched hands fell just short of the blue .45 as he crashed to the floor. The copper ones were upon him.
Half stunned by the fall, he hardly knew when they dragged him to his feet. He was facing the golden figure of Phee-e-al, but now the ruler's indecision had vanished. He was exercising his full authority and even Rawson's throbbing brain comprehended the doom that was being pronounced.
"Gevarro!" he was shrieking. "Gevarro!"
Beside him a priest swept the metal table clear. Rawson's clothing, the gun, the radio receiver, all were snatched up and hurled into one of the massive chests. Phee-e-al was still shouting shrill commands. An instant later Rawson was lifted in air, rushed to the barrier and thrown bodily from the sacred premises he had invaded. Then the hands of the red guard closed about him before he could struggle to his feet. A shining object swung down above his head. It was the last he knew.
H
is dreams were of falling. Always when he half roused to consciousness he was aware of that smooth, even descent, and he knew it had continued for hours.
Once he saw black walls slipping smoothly past, upward, always upward. Gropingly he tried to marshal his facts into some understandable sequence. He was falling, falling toward the center of the earth, and this that he saw was not rock, or any metal such as he knew.
"It's all different," he told himself dully, "new kind of matter. Rock would flow; this stands the pressure." But he knew the air pressure had built up tremendously. The blood was pounding in his ears. He wanted to sleep.
It was the heat that awakened him. The air was stifling him, suffocating. He was struggling to move his heavy body, fighting against this nightmare of heat when he opened his eyes and knew that he was in a place of light. First to be seen were walls, no longer black, no longer even with the characteristics of rock, or even metal. Here, as Rawson had sensed, was new material to form the core of a world. It would have been red in an ordinary light. It was transformed to orange, strangely terrifying in the blazing flood of yellow brilliance that came from the tunnel's end.
Rawson's brain was not working clearly. An unendurable weight seemed pressing upon him—the air pressure, he thought, to which he had not yet become accustomed. And the air, itself, hot—hot!
A breeze blew steadily past toward that place of yellow horror at the tunnel's end. Yellow, that reflected light; but its source was a searing, dazzling white in the one brief instant when Rawson dared turn his eyes.
Hands held him erect, red, gripping hands. One, whose body seemed molten copper in that fierce glare, approached. His hand described a circle over Rawson's bare chest. Straight lines radiated out from the circle, lines of stabbing pain for the helpless man. He had seen the same emblem in the temple of fire, again in the big room where Phee-e-al had stood.
T
he living sacrifice was prepared. Burned into his bare flesh was the emblem of their legendary sun-god. The priests, their bodies coated with a flashing coppery film that must somehow be heat-resistant, had him in their grasp.
The red warriors had fallen back. Then Phee-e-al appeared; he joined the march of death of which Dean Rawson formed the head. Voices were chanting—somewhere a trumpet blared. Then Rawson, moving like one in a dream, knew the priests were guiding him toward that waiting, incredible heat.
The tunnel's end was near. About him was an inferno where heat and hot colors blended. The whole world seemed aflame, but beyond the tunnel's end was a seething pit upon which no human eyes could look and live.
One glimpse only of the unbearable whiteness beneath which was the lake of fire, then the chains of his stupor broke and Dean Rawson struggled frenziedly in the grip of two copper giants.
They had been chanting a shrill monotonous refrain. They ceased now as they fought to throw the man out past that last ten paces where even they dared not go.
Rawson was beyond conscious thought. Eyes closed against the unendurable heat, he fought blindly, desperately, then knew his last strength was going from him. Still struggling he opened his eyes; some thought of meeting death face to face compelled him.
A
hideous coppery face glared close into his own. Miraculously it vanished, disappeared in a cloud of white. Then the blazing walls were gone—there was nothing in all the world but rushing clouds of whiteness, shrieking winds, the roar of an explosion—and cold, so biting that it burned like heat.
Vaguely he wondered at the hands that still clutched at him. Dimly he sensed other bodies close to his, other hands that tore him free where he lay, still struggling with the priests, upon the floor. A narrow opening was in the wall, a blur of darkness in the billowing white clouds. They were dragging him into it, those others who held him, and they were white—white as the vapor that whirled about him.
Ahead, the girl of his former dreams was guiding him, her hand cool and soft in his. Others helped him; he ran stumblingly where they led down a steep and narrow way.
The White Ones! In a vision they had reached out to him before. Was this, too, a dream? Was it only the delirium of death? That burst of cold—had it truly been liquid fires, wrapping him around?
Dean Rawson could not be sure. He knew only that his fate lay wholly in the hands of these White Ones—and that hideous eyes in the coppery face of a priest had glared at them as they fled.
She was motioning for him to follow.She was motioning for him to follow.
D
ean Rawson had passed through a nerve-racking experience. It was not a question of courage—Rawson had plenty of that—but there are times when a man's nervous system is shocked almost to insensibility by sheer horror. Not at once did he realize what was happening.
The Voice of the Mountain heralds Rawson's Messianic coming to the White Ones in their hour of need.
Perhaps it was the sound of pursuit that jarred him out of the fog clouding all his thoughts and perceptions. It was like the sound of fighting animals—cat-beasts—whose snarls had risen to screaming, squalling shrieks of rage. It was sheer beastliness, the din that echoed through that narrow passage.
Ahead of him the girl was running. She held a light in her hand. Soft wrappings of cloth hung loosely from her waist; like her golden hair, it was flung backward in the strong draft of air against which they were struggling. She was outlined clearly before the red, rock-like masses where her light was falling; she was running swiftly, gracefully, like a wild, woodland nymph.
Two men, their milk-white bodies naked but for the thick folds of their loin cloths, were beside Rawson, helping him along. Two others followed. And, by their haste and their odd whispered words of alarm, he knew that pursuit had not been expected; they must have thought to get away unobserved.
Rawson felt his strength returning. He shook himself free from those who tried to aid him. He was amazed at how easily he ran: his weight was a mere nothing; his efforts were expended in driving his body against the blast of wind. The air seemed dense, thick; he had almost the feeling of forcing himself through water.
Ahead of him the girl darted abruptly through a narrow crack in the wall. Rawson followed—and then began a wild race through a network of connecting passages, a vast labyrinth of caves, more like fractures in this strange red substance which Rawson could think of only as rock, for lack of a more accurate name, until at last there was no sound except that of their own hurrying feet.
T
hey stopped and stood panting in one of the wider passages. He heard nothing but the endless rush of the wind. For the first time Rawson became aware of his own almost naked condition.
The mole-men had prepared him for the sacrifice. They had decked him with a loin cloth of woven gold. It felt cold to the touch, and Rawson did not doubt its being made of fine threads of the precious metal. About his neck hung a gold chain with a heavy object suspended; he tore it off, and found again a representation of a golden sun. The copper priests had arrayed him to meet their fire-god, and again Rawson wondered at the emblem they employed.
"What in the name of the starlit heavens," he demanded silently of himself, "could this buried race know of the sun?"
The others were watching him. In the glow of that strange light held by the girl he saw them smiling. They were congratulating one another with odd, soft-syllabled words. And Rawson, ignorant of their tongue, was mute, when his whole soul cried out to thank them.
He gripped the hands of the men. They were as tall as himself, their gaze level with his own. Their faces were human, friendly; their eyes sparkled and smiled into his. Then he turned to the girl.
She had seen the method of greeting this stranger employed. She extended her hand—a white hand, slim, soft, cool. And Rawson, choking with emotion, knowing that here was the one who had first seen him and who had returned to save him, a stranger, bent low above that hand, held in his own so rough and burned, and pressed his lips to the slender fingers in a quick caress.
When he raised his head she was looking at him oddly; her eyes were deep, serious and unsmiling. He wondered if, blunderingly, he had offended her. He could not know; he did not know their customs.
Again the slim girlish figure turned; her jeweled breast-plates flashed as she led the others on where always the way led upward and the wind pressed against them unceasingly.
T
he White Ones wore sandals that seemed woven of glass. Rawson's bare feet were bruised and sore, for those narrower clefts had been paved only with broken fragments of the red walls. He moved less easily now. The heavy, beating air tired him; the lightness of his body made it all the more difficult to fight the steady wind. Still he followed the white figure of the girl where her light was flashing on endless walls of red.
In his ears a new sound was registering. Above the rush of the air, that now was soft and warm, a new note had risen to a hollow, unremitting roar. He knew that for some time he had been hearing it faintly. It grew louder, one long, steady, unchanging note, as they advanced. It was a deafening reverberation that seemed shaking the whole earth when they came at last to an open room.
It beat upon him thunderously. As deep as the deepest tone of a mighty organ, like a thousand gigantic organs welded in one, it roared and shook him through and through with its single note.
Exhausted by his wild flight, surrounded by this maelstrom of sound, he sank to the floor and let his laboring lungs have their way. But his eyes were searching the big room.
T
he great cave was too regularly formed to have had a natural origin. The light that the girl had carried gave only feeble illumination in so great a space that had so evidently been hollowed out of the solid red matter.
The light flashed here and there as the girl and her companions moved away. They were circling the room. Rawson saw the irregular outlines of entrances to many dark passages like the one through which they had come. The red rock-mass seemingly had been riven and torn, and apparently in front of each opening the white figures fought against the rush of outgoing air. Rawson felt the same current sweeping and whirling gustily about him.
Now his companions were across the room, and between him and them in the center of the floor he saw the mouth of a black well, a pit some twenty or more feet across. Directly above, where the red rock stuff formed a domed ceiling, he found a counterpart of the pit below—another great bore or open shaft, roughly circular. Apparently it went straight on up and was a continuation of that lower pit.
"This room was cut out," Rawson was thinking, "by the white people or the mole-men—Lord knows who, or when, or why. Cut out around this big shaft...."
His thoughts trailed off. Even thinking seemed impossible under the battering of the roaring noise that pounded about him. Then another thought pierced through the bedlam. He had found the source of the uproar.
T
hat upper shaft, the hole that went on up, must be plugged. There was no outlet that way, and this air that drove endlessly upward from the room must be coming from the lower shaft. It was striking up into that upper cavity.
An organ pipe, truly. But whence came the unending blast of air to keep that gigantic instrument in operation? Rawson dropped to his knees and crept slowly across the floor toward the pit. He must test his theory—see if that was where the air was driving in.
Just short of the brink he stopped. The girl had called—a cry of alarm. She was running swiftly toward him, circling the pit. And Rawson, as she tugged at him, trying to draw him back, knew that she had mistaken his motive. She had thought he was going to cast himself down.
He did not need to go farther. He was close to the edge. And now, even above that roaring sound he heard the rush of the column of air. He seated himself on the stone floor and smiled up at the girl reassuringly. Her eyes that had been dark with fear changed swiftly to a look so sweetly, beautifully tender that Dean Rawson found himself thrilled and shaken by an emotion that set his nerves to quivering even more than did the sonorous vibration from above.
Her companions had joined her. Dean saw her eyes regarding them steadily. Then, as if reaching some sudden final conclusion in her own mind, she dropped swiftly to her knees beside him, raised one of his hands in hers and pressed her soft lips against it.
And Dean, even had he known their language, could not in that moment have spoken. There had been something in the look of her eyes and the soft touch of her lips that of themselves went far beyond words.
"You darling," he was whispering softly to himself as the girl sprang to her feet and walked swiftly away, the others following.
"An angel, no less—down in this damned place!"
H
e wondered, as he watched the flickering light far across the room, what destination they could be bound for. Surely no one so radiantly beautiful could inhabit a world of endless dungeons like that where the mole-men lived. But if not that, then what? Where would their next journey take them? And in what direction would they go?
Again Rawson's thoughts were submerged beneath his own weariness. This air that beat about him had seemed cool after the terrific heat that drove in off the Lake of Fire. Now he realized that the air itself was hot. His one spurt of strength and energy had been expended.
He watched the men disappear into one of the passages, but he roused himself when they returned. They were clinging to a strange device, a metal cylinder that floated in air above their heads like a dirigible on end. It was about eight feet in diameter and some fourteen feet in height; both upper and lower ends were rounded. A cage of parallel bars enclosed it from end to end; like springs of steel they extended from top to bottom where they curved in and were attached to the rounded ends.
R
awson sat up quickly and stared in startled amazement at the thing glinting like polished aluminum in the light. And his engineer's mind responded as much to that smooth finish and the evident workmanship that had entered into the making of this thing as it did to the object itself.
The girl placed her light on the floor. She, too, reached up and gripped a bar of the protecting cage to which the others were holding. With her added weight and strength they drew it down almost to the floor. Rawson knew by their efforts that they were dealing with something actually buoyant, a metal balloon. One of the men, still putting his weight on the bars, reached in and opened a door in the smooth shell. He stepped inside, and a moment later the big shell dropped to the floor and, still vertical, stood on the lower rounded end of the protecting cage, rocking gently as the hot whirling wind hit it.
They were communicating among themselves by signs. Rawson saw them motioning. Speech was useless in that roaring, pandemonium-filled room.
She was motioning for him to follow. One of the men circled that central pit, came beside Rawson and helped him to his feet, steadying him as they crossed the room. The girl had entered the big metal shell. Dean saw the glow of her torch shining through the open doorway and through two other windows of crystal glass.
The big room had grown dimmer. The high ceiling was lost in murky shadows. All the room was dark save where that light struck upon walls and floor to make them glow blood-red. The waiting lighted shell seemed a haven of refuge. To get inside, close the door, lock out some of this unendurable, battering sound—it was all Rawson asked, all he could think.
The door closed. He was within the shell, standing on a smooth metal floor. The others were beside him. Dully he wondered what wild adventure was ahead.
H
e had expected—he hardly knew what. But there should have been machinery of some sort. If this weird balloon thing was actually to carry them, there must be some mechanism, some propelling power. And instead he saw nothing but the shining walls of the circular room and at the exact center, reaching from floor to ceiling, a six-inch metal post that thickened to a boxlike form on a level with his eyes. There was a plate on the side of that box, a cover, and clamps that held it in place, and on an adjoining side two little levers, one near the top of the box, the other near the bottom.
His one all-inclusive glance showed him bull's-eye windows in the ceiling. There were more of them in the floor. One curved bar, circling the room, was mounted on brackets against the wall. They were telling him by signs that he was to put his hands on it and hang on. One of the men was beside that central post. He too gripped at a projecting hand-hold. His other hand was on the lower lever.
Rawson knew his disappointment was unreasonable, but his weary mind was tired of mysteries. Some understandable bit of machinery would have been reassuring. And then in his next thought he asked himself what difference did it make. If this childish balloon thing were really capable of carrying them somewhere, what of it? It could only mean more of this hideous inner world that grew more unbearably fantastic with each new experience.
His life had been saved. True, but for what end? The girl's eyes were upon him, reading the expression on his face. She smiled encouragingly. Then Rawson's hands tightened upon the metal bar. The man who stood by the central post had moved one lever the merest trifle. Rawson felt the floor lifting beneath him. Then the shell, like a bubble of metal, pitched and tossed as the powerful air currents caught it.
H
is own lightness saved him from injury. He gripped the bar and held himself free of the wall. The round top of their strange craft grated against the domed roof. Then again the ship steadied and seemed motionless, and Rawson knew they had slipped up into the still air of that upper shaft.
For one wild instant, filled with impossible hope, Rawson saw this as a means of ascent to his own world. Then reason tore those wild hopes to shreds.
"It's closed up above," he thought. "It must be. That's why it sounded that way. That's why the air drove off through those side passages."
The next instant held no time for thought. Rawson's whole attention was concentrated upon the bar to which he clung. For, quicker than thought, the metal shell, the little cylindrical world in which he and these others were, fell swiftly beneath them.
His body twisted in mid-air. He knew the others were being thrown in the same manner. Then, what an instant before had been the ceiling was now a floor beneath his feet, pressing up against him and giving him weight—and by the whistling rush of the air that tore past their shell he knew they had fallen with marvelous swiftness straight down through the throat of that lower shaft.
And now what had been down was up. The ceiling of this strange room was now their floor, but Rawson was not deceived. "Acceleration," he said. "It's crowding us. The shell tends to fall faster than we do. It's like an elevator traveling downward at a swifter rate than a free falling body."
H
e had glimpsed the glassy-side of that well into which he knew they had been flung. He knew that the shrieks that filled the room time and again were caused by the touching of their shell's guiding and protecting bars against one glassy wall. Those sounds came always from the same side and Rawson found momentary satisfaction in his own understanding of the phenomenon.
"We're falling free," he argued within his own mind, "falling toward the center of the earth. And a falling body wouldn't follow a vertical course. It would tend to hug against one wall." And by that he knew something of their speed. The necessity for it was apparent a moment later.
Above his head the bull's-eyes pointing forward in the direction of their flight were faintly red. Swiftly they changed to crimson. Rawson was standing beside a window in the wall of their craft. That, too, grew quickly to an area of dazzling brightness. Slowly the heat struck in. The air in the little room was stifling. He saw the girl turn her head and give a sharp order.
The man by the central post responded with another slight movement of the lever. Beneath Rawson's feet the floor pressed upward in a surge of speed that bent his knees and bore him downward. Under his hands the rod to which he clung was hot. The shining walls were dimly glowing. They were being hurled through the very heart of hell....
A
nd then it was past. The crimson horror beyond those windows grew dull and then black. In the blunt nose of their craft a tiny crevice must have opened. The one who drove that projectile in its shrieking flight had touched another control that Rawson had not before seen. And with a piercing shriek a thin jet of cold air drove down into the hot room.
No wine could have been one-half so potent. That thin jet filled the room with buffeting whirlwinds that grew quickly cold.
Then their speed was checked. Abruptly Rawson was weightless, his body hanging in air, moved only as he moved his hand upon the bar. Only a few feet away was the body of the girl floating weightless like himself. The others were shouting loud words of satisfaction, but her face was turned toward Rawson, her eyes were smiling into his; while, outside the little shell that fell in meteor flight, were only shrieking winds and the blackness into which they plunged.
T
hrough an ordinary experience, Dean Rawson, like any other man, would have kept unconscious measurement of the passing time. An hour, no matter how crowded, would still have been an hour that his mind could measure and grasp. But now he had no least idea of the hours or minutes that had marked their flight. Each lagging second was an age in passing. Even the flashing thoughts that drove swiftly through his mind seemed slow and laborious. Painstakingly he marshaled his few facts.
"They know what they're about, that's one thing dead sure. They're onto their job, and they've got something here that beats anything we've ever had." He mentally nailed that one fact down and passed on to the next. "And that's the bow end of our ship, up there." He looked above him at a dented place in the ceiling, the ceiling that had been the floor of the room when first he stepped into it. "There isn't any up or down any more. I've been flipped back and forth every time we slowed down or accelerated until I don't know where I'm at, but I saw that dented plate in the floor when I got in and we started falling in that direction. But whether we're falling toward the center of the earth still or whether we passed the center back there at that hot spot and now this crazy, senseless shell is flying on and up, perhaps these people know—I don't!"
Then fact No. 3. "They live somewhere inside here. They're taking me there, of course. It must mean there's a race of them—and they don't like the mole-men. They know the way back, too, and if they'll help me.... Perhaps the fighting's not over yet!"
Through more endless, age-long seconds there passed through Rawson's mind entrancing visions. An army of men like these White Ones, himself at their head. They were armed with strange weapons; they were invading the mole-men's world....
The girl was reaching toward him. She laid one hand upon his, then pointed overhead.
R
awson looked quickly above. The glowing bull's-eyes startled him, then he knew it was white-light he was seeing, not the red threat of glowing rock. Their speed had been steadily cut down as the air pressure lessened. "They're decompressing," he thought. "They're working slowly into the lesser pressure."
The passing air no longer shrieked insanely. Above its soft rushing sound he heard the girl's voice; it was clear, vibrant with happiness. Her hand closed convulsively over his; her eyes beneath their long lashes smiled unspoken words of welcome, of comradeship, and of something more.
Within their room her light, which at close range seemed only a slender bar of metal with a brilliantly glowing end, had been clamped in a bracket against the wall. The illumination had seemed brilliant, now suddenly it was pale and dim.
Through the bull's-eyes above, a brighter light was shining, clear and golden, like the light of the sun on a brilliant and cloudless day. And to Rawson, who felt that he had spent a lifetime in the gloomy dungeons of that inner world, that flooding brilliance was more than mere light. It was the promise of release, the very essence of hope. His eyes clung to these little round windows; then the larger glass beside him blazed forth with the bright sunlight of an open world that was unbearable to one who had lived so long in darkness.
He held tightly to that slim hand that remained so confidingly within his own.
"It isn't true," Rawson was telling himself frantically. "It can't be true. It must be a delusion, another dream."
He gripped the girl's hand in what must have been a painful clasp. He told himself that she at least was real. Her lovely face was before him when at last he could bear to open his eyes.
A
bout him were the others. The cylinder rested firmly upon a surface of pale-rose quartz. Inside the shell he saw the floor where he had stood, and with that he added one more fact to the few he had gotten together. There was no dent in the floor. The shell's position was reversed. What had been up was now down. Rawson knew he was standing firmly, with what seemed his normal earth weight, upon a smooth surface of rock; he knew that he was standing head down as compared with his position at the beginning of their flight—as compared, too, with the way he had stood in the mole-men's world and in his own world up above.
"I've passed the center of the world." The words were ringing in his brain. And then reason shot in a quick denial. "You're as heavy as you were on earth," he told himself. "You'd have to go through and on to the other side, the opposite surface of the world, before your weight would come back like that!"
"What could it mean?" he was demanding as his eyes came back from the machine and swept around over a gorgeous, glittering panorama of crystal mountains, rose and white. Fields of strange plants, vividly green; a whole world that rioted madly in a luxury of color. Before him the girl stood smiling. Every line of her quivering figure spoke eloquently of her joy in seeing this world through Rawson's eyes.
A
man was approaching, a man like the others, yet whose oval face strangely resembled that of the girl. She led Rawson toward him, then Rawson, stopping, jerked backward in uncontrollable amazement, for the tall man drawing near had spoken. His lips were open, moving, and from them came sounds which to Rawson were absolutely unbelievable:
"Stranger," said the newcomer, "in the name of the Holy Mountain, and in the Mountain's language and words, I bid you welcome."
And Rawson, too stunned for coherent thought, could only stammer in what was half a shout: "But you're speaking my language. You're talking the way we talk on earth. Am I crazy? Stark, raving crazy?"
But even the sound of the man's voice could not have prepared him for what followed. There was amazement written on the face of the man. And the girl who stood beside him—her eyes that had been smiling were wide and staring in utter fear. Then she and the man and the other white figures nearby dropped suddenly to kneel humbly before him. Their faces were hidden from him, covered by their hands as they bent their heads low. He heard the man's voice:
"He speaks with the tongue of the Mountain! He comes from the Land of the Sun, from Lah-o-tah, at the top of the world! And I, Gor, am permitted to hear his voice!"
T
hrough an airplane's thick windows of shatter-proof glass, so tough and resilient that a machine-gun bullet would only make a temporary dent, the midday sun flashed brightly as the big ship rolled. Along each side of the small room, high up under the curve of the cabin roof, windows were ranged. Others like them were in the floor. And, above, the same glass made a transparent dome from which an observer could see on all sides.
Outside was the thunderous roar of ten giant motors, but inside the cabin—the fire-control room of a dreadnought of the air—that blast of sound became more a reverberation and a trembling than actual noise.
Certainly the sound of motors and of slashing propellers, as the battle plane roared up into the sky, did not prevent free conversation among the three men in the room. Yet there was neither laughter nor idle talk.
At a built-in desk, before a battery of instruments, sat Farrell, the captain of the ship. Farther aft, in solidly anchored chairs, Colonel Culver and Smithy were seated. Occasionally the captain spoke into a transmitter, cutting in by phone on different stations about the ship.
"Check up on that right-wing gun, Sergeant—number two of the top wing-battery. Recoil mechanism is reported stiff.... Tell Chicago, Lieutenant, we will want one thousand gallons in the air—gas only—no oil needed.... Gun room? Have the gun crews get some sleep. They'll have to stand by later on...."
Colonel Culver spoke musingly. "Guerilla warfare, the hardest kind to meet."
S
mithy nodded absently. He rose and stared from one of the side windows that was just level with his eyes. He could see nothing but the broad expanse of wing, a sheet of smooth gray metal. Along its leading edge was a row of shimmering disks where great propellers whirled. From the top of the wing a two-inch Rickert recoilless thrust forth its snout; it rose in air till the whole weapon was visible, then settled again and buried itself inside the wing.
They were testing a gun. Smithy knew that inside that wing section were other guns, and men, and smoothly running motors. The whole ship was only a giant flying wing of which their own central section was merely a thickening.
He looked down through a bull's-eye in the floor. The city they had just left was beneath them. Washington, the nation's capital; the golden dome of the Capitol Building was slipping swiftly astern. Only then did he make a belated reply to Culver's statement.
"Well," he said shortly, "they'll have to meet it their own way. We told them all we knew. And a lot of good that did—not!"
"Five days!" said Culver. "It seems more like five years since the devils first came out. Nobody knows where they will hit next. But they're working north—and there's no trouble in telling where they've been."
Smithy's voice was hot in reply, hot with the intense anger of a young, aggressive man when confronted by the ponderous motion of a big organization getting slowly under way.
"If only we'd gone down underground," he exclaimed; "carried the fight to them! They live there—there must be a whole world underground. We could have carried in power lines, lighting the place as we went along. We could have fought 'em with gas. We'd have paid for it, sure we would, but we'd have given them enough hell to think of down below so they wouldn't raise so much of it up above.
"But no! We had to fight according to the textbooks. And those red devils don't fight that way; they never learned the rules."
G
uerilla warfare," Colonel Culver repeated. "There are certain difficulties about fighting enemies you can't see."
"They're clever," Smithy admitted. "We taught them their lesson down there in the desert—they've never been seen in daylight since. Out at night—and their invisible heat-rays setting fire to a city a mile away, then mopping up with their green flame-throwers if anyone's left. They pick our planes out of the sky even when they're flying without lights. Darkness means nothing to them! It was murder to send troops in against them, troops wiped out to a man! Artillery—that's no good either when we don't know how many of the devils there are, or where they are. There's no profit in shelling the place when the brutes have gone back underground."
Colonel Culver shot a warning glance from Smithy to the seated officer. "About a hundred square miles of the finest fruit country on earth laid waste," he admitted gravely; then sought to turn Smithy from his rebellious mood:
"What's underground, I wonder? Must be a world of caves. Or perhaps these mole-men can follow up a mere crack or a fault line and open it out with their flame-throwers to make a tunnel they can go through."
The plane's captain had caught Culver's glance. "Speak your piece," he said pleasantly. "Don't stop on my account. There's a lot to what Mr. Smith says—but you don't know all that's going on."
He had been half turned. Now he swung about in his little swivel chair, whose base was riveted solidly to the floor and whose safety belt ends dangled as he turned.
"My orders are to deliver you two gentlemen at San Francisco. But there's a show scheduled for to-night down south of there—two hundred planes, big and little, scouts, cruisers, battle planes. They're going to swarm in over when the enemy makes his first crack. There's a devil of a storm in the mountains along the route we would usually take. I'm afraid I'll have to swing off south." He was grinning openly as he turned back to his desk.
Colonel Culver smiled back. "Attaboy!" he said.
But Smithy's forehead was still wrinkled in scowling lines as he walked forward to an adjoining room. "Underground," he was thinking. "We've got to carry the fight to them; got to lick 'em so they'll stay licked. But Rawson—good old Dean—we're too late to help him. And the lives of all the devils left in hell can't pay for that."
