"What's that?" cried Tommy sharply, as a rasping sound rose above the cries of the frightened blacks.

But there was no need to ask. Out of the crater two enormous beetles were winging their way toward them, two beetles larger than any that they had seen.

Fully seven feet in length, they were circling about each other, apparently engaged in a vicious battle.

The fearful beaks stabbed at the flesh beneath the shells, and they alternately stabbed and drew back, all the while approaching the party, which watched them, petrified with terror.

It was evident that the monsters had no conception of the presence of humans. Blinded by the sun, only one thing could have induced them to leave the dark depths of Submundia. That was the mating instinct. The beetles were evidently rival leaders of some swarm, engaged in a duel to the death.

Round and round they went in a dizzy maze, stabbing and thrusting, jaws closing on flesh, until they dropped, close-locked in battle, not more than twenty feet from the little party of blacks and whites, both squirming in the agonies of death.

* * * * *

"I don't think that necessarily means that the swarm is on our trail," said Tommy, a little later, as the three stood beside the shells that they had discarded. "Those two were strays, lost from the swarm and maddened by the mating instinct. Still, it might be as well to wear these things for a while, in case they do follow us."

"You're right," answered Dodd, as he placed one of the shells around Haidia. "We've got to get this little lady to civilization, and we've got to protect our lives in order to give this great new knowledge to the world. If we are attacked, you must sacrifice your life for me, Tommy, so that I can carry back the news."

"Righto!" answered Tommy with alacrity. "You bet I will, Jim."

The glaring sun of mid-afternoon was shining down upon the desert, but Haidia was no longer in pain. It was evident that she was fast becoming accustomed to the sunlight, though she still kept her eyes screwed up tightly, and had to be helped along by Dodd and Jimmy. In high good humor the three reached the encampment, to find that the blacks were feasting on the dead beetles, while the two eldest members of the party had proudly donned the shells.

It was near sunset before they finally started. Dodd and Tommy had managed to make it clear to them that they wished to reach civilization, but how near this was there was, of course, no means of determining. They noted, however, that the party started in a southerly direction.

"I should say," said Dodd, "that we are in South Australia, probably three or four hundred miles from the coast. We've got a long journey before us, but these blackfellows will know how to procure food for us."

* * * * *

They certainly knew how to get water, for, just as it began to grow dark, when the three were already tormented by thirst, they stopped at what seemed a mere hollow among the stones and boulders that strewed the face of the desert, and scooped away the sand, leaving a hole which quickly filled with clear, cold water of excellent taste.

After which they made signs that they were to camp there for the night. The moon was riding high in the sky. As it grew dark, Haidia opened her eyes, saw the luminary, and uttered an exclamation, this time not of fear, but of wonder.

"Moon," said Dodd. "That's all right, girl. She watches over the night, as the sun does over the day."

"Haidia likes the moon better than the sun," said the girl wistfully. "But the moon not strong enough to keep away the beetles."

"If I was you, I'd forget about the beetles, Haidia," said Dodd. "They won't come out of that hole in the ground. You'll never see them again."

And, as he spoke, they heard a familiar rasping sound far in the distance.

"How the wind blows," said Tommy, desperately resolved not to believe his ears. "I think a storm's coming up."

But Haidia, with a scream of fear, was clinging to Dodd, and the blacks were on their feet, spears and boomerangs in their hands, looking northward.

Out of that north a little black cloud was gathering. A cloud that spread gradually, as a thunder-cloud, until it covered a good part of the sky. And still more of the sky, and still more. All the while that faint, distant rasping was audible, but it did not increase in volume. It was as if the beetles had halted until the full number of the swarm had come up out of the crater.

* * * * *

Then the cloud, which by now covered half the sky, began to take geometric form. It grew square, the ragged edges seemed to trim themselves away, streaks of light shot through it at right angles, as if it was marshaling itself into companies.

The doomed men and the girl stood perfectly still, staring at that phenomenon. They knew that only a miracle could save them. They did not even speak, but Haidia clung more tightly to Dodd's arm.

Then suddenly the cloud spread upward and covered the face of the moon.

"Well, this is good-by, Tommy," said Dodd, gripping his friend's hand. "God, I wish I had a revolver, or a knife!" He looked at Haidia.

Suddenly the rasping became a whining shriek. A score of enormous beetles, the advance guards of the army, zoomed out of the darkness into a ray of straggling moonlight. Shrieking, the blacks, who had watched the approaching swarm perfectly immobile, threw away the two shells and bolted.

"Good Lord," Dodd shouted, "did you see the color of their shells, Tommy?" Even in that moment the scientific observer came uppermost in him. "Those red edges? They must be young ones, Tommy. It's the new brood! No wonder Bram stayed behind! He was waiting for them to hatch! The new brood! We're doomed—doomed! All my work wasted!"

The blackfellows did not get very far. A hundred yards from the place where they started to run they dropped, their bodies hidden beneath the clustering monsters, their screams cut short as those frightful beaks sought their throats, and those jaws crunched through flesh and bone.

* * * * *

Circling around Dodd, Tommy, and Haidia, as if puzzled by their appearance, the beetles kept up a continuous, furious droning that sounded like the roar of Niagara mixed with the shrieking of a thousand sirens. The moon was completely hidden, and only a dim, nebulous light showed the repulsive monsters as they flew within a few feet of the heads of the fugitives. The stench was overpowering.

But suddenly a ray of white light shot through the darkness, and, with a changed note, just perceptible to the ears of the two men, but doubtless of the greatest significance to the beetles, the swarm fled apart to right and left, leaving a clear lane, through which appeared—Bram, reclining on his shell-couch above his eight trained beetle steeds!

Hovering overhead, the eight huge monsters dropped lightly to the ground beside the three. Bram sat up, a vicious grin upon his twisted face. In his hand he held a large electric bulb, its sides sheathed in a roughly carved wooden frame; the wire was attached to a battery behind him.

"Well met, my friends!" he shouted exultantly. "I owe you more thanks than I can express for having so providentially left the electrical equipment of your plane undamaged after you crashed at the entrance to Submundia. I had a hunch about it—and the hunch worked!"

* * * * *

He grinned more malevolently as he looked from one man to the other.

"You've run your race," he said. "But I'm going to have a little fun with you before you die. I'm going to use you as an object lesson. You'll find it out in a little while."

"Go ahead, go ahead, Bram," Dodd grinned back at him. "Just a few million years ago, and you were a speck of protoplasm—in that pre-pleistocene age—swimming among the invertebrate crustaceans that characterized that epoch."

"Invertebrates and monotremes, Dodd," said Bram, almost wistfully. "The mammals were already existent on the earth, as you know—" Suddenly he broke off, as he realized that Dodd was spoofing him. A yell of execration broke from his lips. He uttered a high whistle, and instantly the whiplike lashes of a hundred beetles whizzed through the darkness and remained poised over Dodd's head.

"Not even the marsupial lion, Bram," grinned Dodd, undismayed. "Go ahead, go ahead, but I'll not die with a lie upon my lips!"

CHAPTER IX

The Trail of Death

"There's sure some sort of hoodoo on these Antarctic expeditions, Wilson," said the city editor of The Daily Record to the star rewrite man. He glanced through the hastily typed report that had come through on the wireless set erected on the thirty-sixth story of the Record Building. "Tommy Travers gone, eh? And James Dodd, too! There'll be woe and wailing along the Great White Way to-night when this news gets out. They say that half the chorus girls in town considered themselves engaged to Tommy. Nice fellow, too! Always did like him!"

"Queer, that curtain of fog that seems to lie on the actual site of the south pole," he continued, glancing over the report again. "So Storm thinks that Tommy crashed in it, and that it's a million to one against their ever finding his remains. What's this about beetles? Shells of enormous prehistoric beetles found by Tommy and Dodd! That'll make good copy, Wilson. Let's play that up. Hand it to Jones, and tell him to scare up a catching headline or two."

* * * * *

He beckoned to the boy who was hurrying toward his desk, a flimsy in his hand, glanced through it, and tossed it toward Wilson.

"What do they think this is, April Fool's Day?" he asked. "I'm surprised that the International Press should fall for such stuff as that!"

"Why, to-morrow is the first of April!" exclaimed Wilson, tossing back the cable dispatch with a contemptuous laugh.

"Well, it won't do the I. P. much good to play those tricks on their subscribers," said the city editor testily. "I'm surprised, to say the least. I guess their Adelaide correspondent has gone off his head or something. Using poor Travers's name, too! Of course that fellow didn't know he was dead, but still...."

That was how The Daily Record missed being the first to give out certain information that was to stagger the world. The dispatch, which had evidently outrun an earlier one, was as follows:

ADELAIDE, South Australia, March 31.—Further telegraphic communications arriving almost continuously from Settler's Station, signed by Thomas Travers, member of Travers Antarctic Expedition, who claims to have penetrated earth's interior at south pole and to have come out near Victoria Desert. Travers states that swarm of prehistoric beetles, estimated at two trillion, and as large as men, with shells impenetrable by rifle bullets, now besieging Settler's Station, where he and Dodd and Haidia, woman of subterranean race whom they brought away, are shut up in telegraph office. Bram, former member of Greystoke Expedition, said to be in charge of swarm, with intention of obliterating human race. Every living thing at Settler's Station destroyed, and swarm moving south.

It was a small-town paper a hundred miles from New York that took a chance on publishing this report from the International Press, in spite of frantic efforts on the parts of the head office to recall it after it had been transmitted. This paper published the account as an April Fool's Day joke, though later it took to itself the credit for having believed it. But by the time April Fool's Day dawned all the world knew that the account was, if anything, an under-estimate of the fearful things that were happening "down under."

* * * * *

It was known now that the swarm of monsters had originated in the Great Victoria Desert, one of the worst stretches of desolation in the world, situated in the south-east corner of Western Australia. Their numbers were incalculable. Wimbush, the aviator, who was attempting to cross the continent from east to west, reported afterward that he had flown for four days, skirting the edge of the swarm, and that the whole of that time they were moving in the same direction, a thick cloud that left a trail of dense darkness on earth beneath them, like the path of an eclipse. Wimbush escaped them only because he had a ceiling of twenty thousand feet, to which apparently the beetles could not soar.

And this swarm was only about one-fourth of the whole number of the monsters. This was the swarm that was moving westward, and subsequently totally destroyed all living things in Kalgoorlie, Coolgardie, Perth, and all the coastal cities of Western Australia.

Ships were found drifting in the Indian Ocean, totally destitute of crews and passengers; not even their skeletons were found, and it was estimated that the voracious monsters had carried them away bodily, devoured them in the air, and dropped the remains into the water.

All the world knows now how the sea elephant herd on Kerguelen Island was totally destroyed, and of the giant shells that were found lying everywhere on the deserted beaches, in positions that showed the monsters had in the end devoured one another.

Mauritius was the most westerly point reached by a fraction of the swarm. A little over twenty thousand of the beetles reached that lovely island, by count of the shells afterward, and all the world knows now of the desperate and successful fight that the inhabitants waged against them. Men and women, boys and girls, blacks and whites, finding that the devils were invulnerable against rifle fire, sallied forth boldly with knives and choppers, and laid down a life for a life.

* * * * *

On the second day after their appearance, the main swarm, a trillion and a half strong, reached the line of the transcontinental railway, and moved eastward into South Australia, traveling, it was estimated, at the rate of two hundred miles an hour. By the next morning they were in Adelaide, a city of nearly a quarter of a million people. By nightfall every living thing in Adelaide and the suburbs had been eaten, except for a few who succeeded in hiding in walled-up cellars, or in the surrounding marshes.

That night the swarm was on the borders of New South Wales and Victoria, and moving in two divisions toward Melbourne and Sydney.

The northern half, it was quickly seen, was flying "wild," with no particular objective, moving in a solid cohort two hundred miles in length, and devouring game, stock, and humans indiscriminately. It was the southern division, numbering perhaps a trillion, that was under command of Bram, and aimed at destroying Melbourne as Adelaide had been destroyed.

Bram, with his eight beetle steeds, was by this time known and execrated throughout the world. He was pictured as Anti-Christ, and the fulfilment of the prophecies of the Rock of Revelations.

And all this while—or, rather, until the telegraph wires were cut—broken, it was discovered later, by perching beetles—Thomas Travers was sending out messages from his post at Settler's Station.

* * * * *

Soon it was known that prodigious creatures were following in the wake of the devastating horde. Mantises, fifteen feet in height, winged things like pterodactyls, longer than bombing airplanes, followed, preying on the stragglers. But the main bodies never halted, and the inroads that the destroyers made on their numbers were insignificant.

Before the swarm reached Adelaide the Commonwealth Government had taken action. Troops had been called out, and all the available airplanes in the country had been ordered to assemble at Broken Hill, New South Wales, a strategic point commanding the approaches to Sydney and Melbourne. Something like four hundred airplanes were assembled, with several batteries of anti-aircraft guns that had been used in the Great War. Every amateur aviator in Australia was on the spot, with machines ranging from tiny Moths to Handley-Pages—anything that could fly.

Nocturnal though the beetles had been, they no longer feared the light of the sun. In fact, it was ascertained later that they were blind. An opacity had formed over the crystalline lens of the eye. Blind, they were no less formidable than with their sight. They existed only to devour, and their numbers made them irresistible, no matter which way they turned.

As soon as the vanguard of the dark cloud was sighted from Broken Hill, the airplanes went aloft. Four hundred planes, each armed with machine guns, dashed into the serried hosts, drumming out volleys of lead. In a long line, extending nearly to the limits of the beetle formation, thus giving each aviator all the room he needed, the planes gave battle.

* * * * *

The first terror that fell upon the airmen was the discovery that, even at close range, the machine gun bullets failed to penetrate the shells. The force of the impact whirled the beetles around, drove them together in bunches, sent them groping with weaving tentacles through the air—but that was all. On the main body of the invaders no impression was made whatever.

The second terror was the realization that the swarm, driven down here and there from an altitude of several hundred feet, merely resumed their progress on the ground, in a succession of gigantic leaps. Within a few minutes, instead of presenting an inflexible barrier, the line of airplanes was badly broken, each plane surrounded by swarms of the monsters.

Then Bram was seen. And that was the third terror, the sight of the famous beetle steeds, four pairs abreast, with Bram reclining like a Roman emperor upon the surface of the shells. It is true, Bram had no inclination to risk his own life in battle. At the first sight of the aviators he dodged into the thick of the swarm, where no bullet could reach him. Bram managed to transmit an order, and the beetles drew together.

Some thought afterward that it was by thought transference he effected this maneuver, for instantly the beetles, which had hitherto flown in loose order, became a solid wall, a thousand feet in height, closing in on the planes. The propellers struck them and snapped short, and as the planes went weaving down, the hideous monsters leaped into the cockpits and began their abominable meal.

* * * * *

Not a single plane came back. Planes and skeletons, and here and there a shell of a dead beetle, itself completely devoured, were all that was found afterward.

The gunners stayed at their posts till the last moment, firing round after round of shell and shrapnel, with insignificant results. Their skeletons were found not twenty paces from their guns—where the Gunners' Monument now stands.

Half an hour after the flight had first been sighted the news was being radioed to Sydney, Melbourne, and all other Australian cities, advising instant flight to sea as the only chance of safety. That radio message was cut short—and men listened and shuddered. After that came the crowding aboard all craft in the harbors, the tragedies of the Eustis, the All Australia, the Sepphoris, sunk at their moorings. The innumerable sea tragedies. The horde of fugitives that landed in New Zealand. The reign of terror when the mob got out of hand, the burning of Melbourne, the sack of Sydney.

And south and eastward, like a resistless flood, the beetle swarm came pouring. Well had Bram boasted that he would make the earth a desert!

* * * * *

A hundred miles of poisoned carcasses of sheep, extended outside Sydney's suburbs, gave the first promise of success. Long mounds of beetle shells testified to the results; moreover, the beetles that fed on the carcasses of their fellows, were in turn poisoned and died. But this was only a drop in the bucket. What counted was that the swift advance was slowing down. As if exhausted by their efforts, or else satiated with food, the beetles were doing what the soldiers did.

They were digging in!

Twenty-four miles from Sydney, eighteen outside Melbourne, the advance was stayed.

Volunteers who went out from those cities reported that the beetles seemed to be resting in long trenches that they had excavated, so that only their shells appeared above ground. Trees were covered with clinging beetles, every wall, every house was invisible beneath the beetle armor.

Australia had a respite. Perhaps only for a night or day, but still time to draw breath, time to consider, time for the shiploads of fugitives to get farther from the continent that had become a shambles.

And then the cry went up, not only from Australia, but from all the world, "Get Travers!"

CHAPTER X

At Bay

Bram put his fingers to his mouth and whistled, a shrill whistle, yet audible to Dodd, Tommy, and Haidia. Instantly three pairs of beetles appeared out of the throng. Their tentacles went out, and the two men and the girl found themselves hoisted separately upon the backs of the pairs. Next moment they were flying side by side, high in the air above the surrounding swarm.

They could see one another, but it was impossible for them to make their voices heard above the rasping of the beetles' legs. Hours went by, while the moon crossed the sky and dipped toward the horizon. Tommy knew that the moon would set about the hour of dawn. And the stars were already beginning to pale when he saw a line of telegraph poles, then two lines of shining metals, then a small settlement of stone and brick houses.

Tommy was not familiar with the geography of Australia, but he knew this must be the transcontinental line.

Whirling onward, the cloud of beetles suddenly swooped downward. For a moment Tommy could see the frightened occupants of the settlement crowding into the single street, then he shuddered with sick horror as he saw them obliterated by the swarm.

There was no struggle, no attempt at flight or resistance. One moment those forty-odd men were there—the next minute they existed no longer. There was nothing but a swarm of beetles, walking about like men with shells upon their backs.

And now Tommy saw evidences of Bram's devilish control of the swarm. For out of the cloud dropped what seemed to be a phalanx of beetle guards, the military police of beetledom, and, lashing fiercely with their tentacles, they drove back all the swarm that sought to join their companions in their ghoulish feast. There was just so much food and no more; the rest must seek theirs further.

* * * * *

But even beetles, it may be presumed, are not entirely under discipline at all times. The pair of beetles that bore Tommy, suddenly swooped apart, ten or a dozen feet from the ground, and dashed into the thick of the struggling, frenzied mass, flinging their rider to earth.

Tommy struck the soft sand, sat up, half dazed, saw his shell lying a few feet away from him, and retrieved it just as a couple of the monsters came swooping down at him.

He looked about him. Not far away stood Dodd and Haidia, with their shells on their backs. They recognized Tommy and ran toward him.

Not more than twenty yards away stood the railroad station, with several crates of goods on the platform. Next to it was a substantial house of stone, with the front door open.

Tommy pointed to it, and Dodd understood and shouted something that was lost in the furious buzz of the beetles' wings as they devoured their prey. The three raced for the entrance, gained it unmolested, and closed the door.

There was a key in the door, and it was light enough for them to see a chain, which Dodd pulled into position. There was only one story, and there were three rooms, apparently, with the kitchen. Tommy rushed to the kitchen door, locked it, too, and, with almost super-human efforts, dragged the large iron stove against it. He rushed to the window, but it was a mere loophole, not large enough to admit a child. Nevertheless, he stood the heavy table on end so that it covered it. Then he ran back.

* * * * *

Dodd had already barricaded the window of the larger room, which was a bed-sitting room, with a heavy wardrobe, and the wooden bedstead, jamming the two pieces sidewise against the wall, so that they could not be forced apart without being demolished. He was now busy in the smaller room, which seemed to be the station-master's office, dragging an iron safe across the floor. But the window was criss-crossed with iron bars, and it was evident that the safe, which was locked, contained at times considerable money, for the window could hardly have been forced save by a charge of nitro-glycerine or dynamite. However, it was against the door that Dodd placed the safe, and he stood back, panting.

"Good," said Haidia. "That will hold them."

The two men looked at her doubtfully. Did Haidia know what she was talking about?

The sun had risen. A long shaft shot into the room. Outside the beetles were still buzzing as they turned over the vestiges of their prey. There were as yet no signs of attack. Suddenly Tommy grasped Dodd's arm.

"Look!" he shouted, pointing to a corner which had been in gloom a moment before.

There was a table there, and on it a telegraphic instrument. Telegraphy had been one of Tommy's hobbies in boyhood. In a moment he was busy at the table.

Dot-dash-dot-dash! Then suddenly outside a furious hum, and the impact of beetle bodies against the front door.

* * * * *

Tommy got up, grinning. That was the first, interrupted message from Tommy that was received.

Through the barred window the three could see the furious efforts of the beetles to force an entrance. But the very tensile strength of the beetle-shells, which rendered them impervious to bullets, required a laminate construction which rendered them powerless against brick or stone.

Desperately the swarm dashed itself against the walls, until the ground outside was piled high with stunned beetles. Not the faintest impression was made on the defenses.

"Watch them, Jim," said Tom. "I'll go see if the rear's secure."

That thought of his seemed to have been anticipated by the beetles, for as Tommy reached the kitchen the swarm came dashing against door and window, always recoiling. Tommy came back, grinning all over his face.

"You were right, Haidia," he said. "We've held them all right, and the tables are turned on Bram. Also I got a message through, I think," he added to Dodd.

Dash—dot—dash—dot from the instrument. Tommy ran to the table again. Dash—dot went back. For five minutes Tommy labored, while the beetles hammered now on one door, now on another, now on the windows. Then Tommy got up.

"It was some station down the line," he said. "I've told them, and they're sending a man up here to replace the telegraphist, also a couple of cops. They think I'm crazy. I told them again. That's the best I could do."

* * * * *

"Dodd! Travers! For the last time—let's talk!"

The cloud of beetles seemed to have thinned, for the sun was shining into the room. Bram's voice was perfectly audible, though he himself was invisible; probably he thought it likely that the defenders had obtained firearms.

"Nothing to say to you, Bram," called Dodd. "We've finished our discussion on the monotremes."

"I want you fellows to stand in with me," came Bram's plaintive tones. "It's so lonesome all by one's self, Dodd."

"Ah, you're beginning to find that out, are you?" Dodd could not resist answering. "You'll be lonelier yet before you're through."

"Dodd, I didn't bring that swarm up here. I swear it. I've been trying to control them from the beginning. I saw what was coming. I believe I can avert this horror, drive them into the sea or something like that. Don't make me desperate, Dodd.

"And listen, old man. About those monotremes—sensible men don't quarrel over things like that. Why can't we agree to differ?"

"Ah, now you're talking, Bram," Dodd answered. "Only you're too late. After what's happened here to-day, we'll have no truck with you. That's final."

"Damn you," shrieked Bram. "I'll batter down this house. I'll—"

"You'll do nothing, Bram, because you can't," Dodd answered. "Travers has wired full information about your devil-horde, and likewise about you, and all Australia will be prepared to give you a warm reception when you arrive."

"I tell you I'm invincible," Bram screamed. "In three days Australia will be a ruin, a depopulated desert. In a week, all southern Asia, in three weeks Europe, in two months America."

"You've been taking too many of those pellets, Bram," Dodd answered. "Stand back now! Stand back, wherever you are, or I'll open the door and throw the slops over you."

* * * * *

Bram's screech rose high above the droning of the wings. In another moment the interior of the room had grown as black as night. The rattle of the beetle shells against the four walls of the house was like the clattering of stage thunder.

All through the darkness Dodd could hear the unhurried clicking of the key.

At last the rattling ceased. The sun shone in again. The ground all around the house was packed with fallen beetles, six feet high, a writhing mass that creaked and clattered as it strove to disengage itself.

Bram's voice once more: "I'm leaving a guard, Dodd. They'll get you if you try to leave. But they won't eat you. I'm going to have you three sliced into little pieces, the Thousand Deaths of the Chinese. The beetles will eat the parts that are sliced away—and you'll live to watch them. I'll be back with a stick or two of dynamite to-morrow."

"Yeah, but listen, Bram," Dodd sang out. "Listen, you old marsupial tiger. When those pipe dreams clear away, I'm going to build a gallows of beetle-shells reaching to the moon, to hang you on!"

Bram's screech of madness died away. The strident rasping of the beetles' legs began again. For hours the three heard it; it was not until nightfall that it died away.

* * * * *

Bram had made good his threat, for all around the house, extending as far as they could see, was the host of beetle-guards. To venture out, even with their shells about them, was clearly a hazardous undertaking. There was neither food nor water in the place.

"We'll just have to hold out," said Dodd, breaking one of the long periods of silence.

Tommy did not answer; he did not hear him, for he was busy at the key. Suddenly he leaped to his feet.

"God, Jimmy," he cried, "that devil's making good his threat! The swarm's in South Australia, destroying every living thing, wiping out whole towns and villages! And they—they believe me now!"

He sank into a chair. For the first time the strain of the awful past seemed to grip him. Haidia came to his side.

"The beetles are finish," she said in her soft voice.

"How d'you know, Haidia?" demanded Dodd.

"The beetles are finish," Haidia repeated quietly, and that was all that Dodd could get out of her. But again the key began to click, and Tommy staggered to the table. Dot—dash—dash—dot. Presently he looked up once more.

"The swarm's halfway to Adelaide," he said. "They want to know if I can help them. Help them!" He burst into hysterical laughter.

Toward evening he came back after an hour at the key. "Line must be broken," he said. "I'm getting nothing."

* * * * *

In the moonlight they could see the huge compound eyes of the beetle guards glittering like enormous diamonds outside. They had not been conscious of thirst during the day, but now, with the coming of the cool night their desire for water became paramount.

"Tommy, there must be water in the station," said Dodd. "I'm going to get a pitcher from the kitchen and risk it, Tommy. Take care of Haidia if—" he added.

But Haidia laid her hand upon his arm. "Do not go, Jimmydodd," she said. "We can be thirsty to-night, and to-morrow the beetles will be finish."

"How d'you know?" asked Dodd again. But now he realized that Haidia had never learned the significance of an interrogation. She only repeated her statement, and again the two men had to remain content.

The long night passed. Outside the many facets of the beetle eyes. Inside the two men, desperate with anxiety, not for themselves, but for the fate of the world, snatching a few moments' sleep from time to time, then looking up to see those glaring eyes from the silent watchers.

Then dawn came stealing over the desert, and the two shook themselves free from sleep. And now the eyes were gone.

But there was immense activity among the beetles. They were scurrying to and fro, and, as they watched, Dodd and Tommy began to see some significance in their movements.

"Why, they're digging trenches!" Tommy shouted. "That's horrible, Jimmy! Are they intending to conduct sapping operations against us like engineers, or what?"

Dodd did not reply, and Tommy hardly expected any answer. As the two men, now joined by Haidia, watched, they saw that the beetles were actually digging themselves into the sand.

* * * * *

Within the space of an hour, by the time the first shafts of sunlight began to stream into the room, there was to be seen only the massive, rounded shells of the monsters as they squatted in the sand.

"Now you may fetch water," said Haidia, smiling at her lover. "No, you do not need the shells," she added. "The beetles are finish. It is as the wise men of my people told me."

Wondering, hesitating, Tommy and Dodd unlocked the front door. They stood upon the threshold ready to bolt back again. But there was no stirring among the beetle hosts.

Growing bolder, they advanced a few steps; then, shamed by Haidia's courage, they followed her, still cautiously to the station.

Dodd shouted as he saw a water-tank, and a receptacle above it with a water-cock. They let Haidia drink, then followed suit, and for a few moments, as they appeased their thirst, the beetles were forgotten.

Then they turned back. There had been no movement in that line of shells that glinted in the morning sunlight.

"Come, I shall show you," said Haidia confidently, advancing toward the trench.

Dodd would have stopped her, but the girl moved forward quickly, eluded him with a graceful, mirthful gesture, and stooped down over the trench.

She rose up, raising in her arms an empty beetle-shell!

Dodd, who had reached the trench before Tommy, turned round and yelled to him excitedly. Tommy ran forward—and then he understood.

The shells were empty. The swarm, whose life cycle Bram had admitted he did not understand, had just moulted!

It had moulted because the bodies, gorged with food, had grown too large for the shells. In time, if left alone, the monsters would grow larger shells, become invincible again. But just now they were defenseless as new-born babes—and knew it.

Deep underneath the empty shells they had burrowed into the ground. Everywhere at the bottom of the deep trenches were the naked, bestial creatures, waving helpless tentacles and squirming over one another as they strove to find shelter and security.

A sudden madness came over Tommy and Dodd. "Dynamite—there must be dynamite!" Dodd shouted, as he ran back to the station.

"Something better than dynamite," shouted Tommy, holding up one of a score of drums of petrol!

CHAPTER XI

The World Set Free

They waited two days at Settler's Station. To push along the line into the desert would have been useless, and both men were convinced that an airplane would arrive for them. But it was not until the second afternoon that the aviator arrived, half-dead with thirst and fatigue, and almost incoherent.

His was the last plane on the Australian continent. He brought the news of the destruction of Adelaide, and of the siege of Melbourne and Sydney, as he termed it. He told Dodd and Tommy that the two cities had been surrounded with trenches and barbed wire. Machine guns and artillery were bombarding the trenches in which the beetles had taken shelter.

"Has any one been out on reconnaissance?" asked Tommy.

Nobody had been permitted to pass through the barbed wire, though there had been volunteers. It meant certain death. But, unless the beetles were sapping deep in the ground, what their purpose was, nobody knew.

* * * * *

Tommy and Dodd led him to the piles of smoking, stinking debris and told him.

That was where the aviator fainted from sheer relief.

"The Commonwealth wants you to take supreme command against the beetles," he told Tommy, when he had recovered. "I'm to bring you back. Not that they expect me back. But—God, what a piece of news! Forgive my swearing—I used to be a parson. Still am, for the matter of that."

"How are you going to bring us three back in your plane?" asked Tommy.

"I shall stay here with Jimmydodd," said Haidia suavely. "There is not the least danger any more. You must destroy the beetles before their shells have grown again, that's all."

"Used to be a parson, you say? Still are?" shouted Dodd excitedly. "Thank God! I mean, I'm glad to hear it. Come inside, and come quick. I want you too, Tommy!"

Then Tommy understood. And it seemed as if Haidia understood, by some instinct that belongs exclusively to women, for her cheeks were flushed as she turned and smiled into Dodd's eyes.

Ten minutes later Tommy hopped into the biplane, leaving the happy married couple at Settler's Station. His eyes grew misty as the plane took the air, and he saw them waving to him from the ground. Dodd and Haidia and he had been through so many adventures, and had reached safety. He must not fail.

* * * * *

He did not fail. He found himself at Sydney in command of thirty thousand men, all enthusiastic for the fight for the human race, soldiers and volunteers ready to fight until they dropped. When the news of the situation was made public, an immense wave of hope ran through the world.

National differences were forgotten, color and creed and race grew more tolerant of one another. A new day had dawned—the day of humanity's true liberation.

Tommy's first act was to call out the fire companies and have the beetles' trenches saturated with petrol from the fire hoses. Then incendiary bullets, shot from guns from a safe distance, quickly converted them into blazing infernos.

But even so only a tithe of the beetle army had been destroyed. Two hundred planes had already been rushed from New Zealand, and their aviators went up and scoured the country far and wide. Everywhere they found trenches, and, where the soil was stony, millions of the beetles clustered helplessly beneath great mounds of discarded shells.

An army of black trackers had been brought in planes from all parts of the country, and they searched out the beetle masses everywhere along the course that the invaders had taken. Then incendiary bombs were dropped from above.

* * * * *

Day after day the beetle massacre went on. By the end of a week the survivors of the invasion began to take heart again. It was certain that the greater portion of the horde had been destroyed.

There was only one thing lacking. No trace of Bram had been seen since his appearance at the head of his beetle army in front of Broken Hill. And louder and more insistent grew the world clamor that he should be found, and put to death in some way more horrible than any yet devised.

The ingenuity of a million minds worked upon this problem. Newspapers all over the world offered prizes for the most suitable form of death. Ingenious Oriental tortures were rediscovered.

The only thing lacking was Bram.

A spy craze ran through Australia. Five hundred Brams were found, and all of them were in imminent danger of death before they were able to prove an alias.

And, oddly enough, it was Tommy and Dodd who found Bram. For Dodd had been brought back east, together with his bride, and given an important command in the Army of Extermination.

* * * * *

Dodd had joined Tommy not far from Broken Hill, where a swarm of a hundred thousand beetles had been found in a little known valley. The monsters had begun to grow new shells, and the news had excited a fresh wave of apprehension. The airplanes had concentrated for an attack upon them, and Tommy and Dodd were riding together, Tommy at the controls, and Dodd observing.

Dodd called through the tube to Tommy, and indicated a mass that was moving through the scrub—some fifty thousand beetles, executing short hops and evidently regaining some vitality. Tommy nodded.

He signalled, and the fleet of planes circled around and began to drop their incendiary bombs. Within a few minutes the beetles were ringed with a wall of fire. Presently the whole terrain was a blazing furnace.

Hours later, when the fires had died away, Tommy and Dodd went down to look at the destruction that had been wrought. The scene was horrible. Great masses of charred flesh and shell were piled up everywhere.

"I guess that's been a pretty thorough job," said Tommy. "Let's get back, Jim."

"What's that?" cried Dodd, pointing. Then, "My God, Tommy, it's one of our men!"

* * * * *

It was a man, but it was not one of their men, that creeping, maimed, half-cinder and half-human thing that was trying to crawl into the hollow of a rock. It was Bram, and recognition was mutual.

Bram dropping, moaning; he was only the shell of a man, and it was incredible how he had managed to survive that ordeal of fire. The remainder of his life, which only his indomitable will had held in that shattered body, was evidently a matter of minutes, but he looked up at Dodd and laughed.

"So—you're—here, damn you!" he snarled. "And—you think—you've won. I've—another card—another invasion of the world—beside which this is child's play. It's an invasion—"

Bram was going, but he pulled himself together with a supreme effort.

"Invasion by—new species of—monotremes," he croaked. "Deep down in—earth. Was saving to—prove you the liar you are. Monotremes—egg-laying platypus big as an elephant—existent long before pleistocene epoch—make you recant, you lying fool!"

Bram died, an outburst of bitter laughter on his lips. Dodd stood silent for a while; then reverently he removed his hat.

"He was a madman and a devil, but he had the potentialities of a god, Tommy," he said.

ASTOUNDING STORIES

* * * * *



Mad Music

By Anthony Pelcher

The sixty stories of the perfectly constructed Colossus building had mysteriously crashed! What was the connection between this catastrophe and the weird strains of the Mad Musician's violin?



To the accompaniment of a crashing roar, not unlike rumbling thunder, the proud Colossus Building, which a few minutes before had reared its sixty stories of artistic architecture towards the blue dome of the sky, crashed in a rugged, dusty heap of stone, brick, cement and mortar. The steel framework, like the skeleton of some prehistoric monster, still reared to dizzy heights but in a bent and twisted shape of grotesque outline.

No one knew how many lives were snuffed out in the avalanche.

As the collapse occurred in the early dawn it was not believed the death list would be large. It was admitted, however, that autos, cabs and surface cars may have been caught under the falling rock. One train was known to have been wrecked in the subway due to a cave-in from the surface under the ragged mountain of debris.

The litter fairly filled a part of Times Square, the most congested cross-roads on God's footstool. Straggling brick and rock had rolled across the street to the west and had crashed into windows and doors of innocent small tradesmen's shops.

A few minutes after the crash a mad crowd of people had piled from subway exits as far away as Penn Station and Columbus Circle and from cross streets. These milled about, gesticulating and shouting hysterically. All neighboring police stations were hard put to handle the growing mob.

Hundreds of dead and maimed were being carried to the surface from the wrecked train in the subway. Trucks and cabs joined the ambulance crews in the work of transporting these to morgues and hospitals. As the morning grew older and the news of the disaster spread, more milling thousands tried to crowd into the square. Many were craning necks hopelessly on the outskirts of the throng, blocks away, trying vainly to get a view of what lay beyond.

The fire department and finally several companies of militia joined the police in handling the crowd. Newsies, never asleep, yowled their "Wuxtras" and made much small money.

The newspapers devoted solid pages in attempting to describe what had happened. Nervously, efficient reporters had written and written, using all their best adjectives and inventing new ones in attempts to picture the crash and the hysterics which followed.

* * * * *

When the excitement was at its height a middle-aged man, bleeding at the head, clothes torn and dusty, staggered into the West 47th street police station. He found a lone sergeant at the desk.

The police sergeant jumped to his feet as the bedraggled man entered and stumbled to a bench.

"I'm Pat Brennan, street floor watchman of the Colossus," he said. "I ran for it. I got caught in the edge of the wreck and a brick clipped me. I musta been out for some time. When I came around I looked back just once at the wreck and then I beat it over here. Phone my boss."

"I'll let you phone your boss," said the sergeant, "but first tell me just what happened."

"Earthquake, I guess. I saw the floor heaving in waves. Glass was crashing and falling into the street. All windows in the arcade buckled, either in or out. I ran into the street and looked up. God, what a sight! The building from sidewalk to towers was rocking and waving and twisting and buckling and I saw it was bound to crumple, so I lit out and ran. I heard a roar like all Hell broke loose and then something nicked me and my light went out."

"How many got caught in the building?"

"Nobody got out but me, I guess. There weren't many tenants. The building is all rented, but not everybody had moved in yet and those as had didn't spend their nights there. There was a watchman for every five stories. An engineer and his crew. Three elevator operators had come in. There was no names of tenants in or out on my book after 4 A.M. The crash musta come about 6. That's all."

* * * * *

Throughout the country the news of the crash was received with great interest and wonderment, but in one small circle it caused absolute consternation. That was in the offices of the Muller Construction Company, the builders of the Colossus. Jason V. Linane, chief engineer of the company, was in conference with its president, James J. Muller.

Muller sat with his head in his hands, and his face wore an expression of a man in absolute anguish. Linane was pacing the floor, a wild expression in his eyes, and at times he muttered and mumbled under his breath.

In the other offices the entire force from manager to office boys was hushed and awed, for they had seen the expressions on the faces of the heads of the concern when they stalked into the inner office that morning.

Muller finally looked up, rather hopelessly, at Linane.

"Unless we can prove that the crash was due to some circumstance over which we had no control, we are ruined," he said, and there actually were tears in his eyes.

"No doubt about that," agreed Linane, "but I can swear that the Colossus went up according to specifications and that every ounce and splinter of material was of the best. The workmanship was faultless. We have built scores of the biggest blocks in the world and of them all this Colossus was the most perfect. I had prided myself on it. Muller, it was perfection. I simply cannot account for it. I cannot. It should have stood up for thousands of years. The foundation was solid rock. It positively was not an earthquake. No other building in the section was even jarred. No other earthquake was ever localized to one half block of the earth's crust, and we can positively eliminate an earthquake or an explosion as the possible cause. I am sure we are not to blame, but we will have to find the exact cause."

"If there was some flaw?" questioned Muller, although he knew the answer.

"If there was some flaw, then we're sunk. The newspapers are already clamoring for probes, of us, of the building, of the owners and everybody and everything. We have got to have something damned plausible when we go to bat on this proposition or every dollar we have in the world will have to be paid out."

"That is not all," said Muller: "not only will we be penniless, but we may have to go to jail and we will never be able to show our faces in reputable business circles again. Who was the last to go over that building?"

"I sent Teddy Jenks. He is a cub and is swell headed and too big for his pants, but I would bank my life on his judgment. He has the judgment of a much older man and I would also bank my life and reputation on his engineering skill and knowledge. He pronounced the building positively O.K.—100 per cent."

"Where is Jenks?"

"He will be here as soon as his car can drive down from Tarrytown. He should be here now."

* * * * *

As they talked Jenks, the youngest member of the engineering force, entered. He entered like a whirlwind. He threw his hat on the floor and drew out a drawer of a cabinet. He pulled out the plans for the Colossus, big blue prints, some of them yards in extent, and threw them on the floor. Then he dropped to his knees and began poring over them.

"This is a hell of a time for you to begin getting around," exploded Muller. "What were you doing, cabareting all night?"

"It sure is terrible—awful," said Jenks, half to himself.

"Answer me," thundered Muller.

"Oh yes," said Jenks, looking up. He saw the look of anguish on his boss's face and forgot his own excitement in sympathy. He jumped to his feet, placed his arm about the shoulders of the older man and led him to a chair. Linane only scowled at the young man.

"I was delayed because I stopped by to see the wreck. My God, Mr. Muller, it is awful." Jenks drew his hand across his eye as if to erase the scene of the wrecked building. Then patting the older man affectionately on the back he said:

"Buck up. I'm on the job, as usual. I'll find out about it. It could not have been our fault. Why man, that building was as strong as Gibraltar itself!"

"You were the last to inspect it," accused Muller, with a break in his voice.

"Nobody knows that better than I, and I can swear by all that's square and honest that it was no fault of the material or the construction. It must have been—"

"Must have been what?"

"I'll be damned if I know."

"That's like him," said Linane, who, while really kindly intentioned, had always rather enjoyed prodding the young engineer.

"Like me, like the devil," shouted Jenks, glaring at Linane. "I suppose you know all about it, you're so blamed wise."

"No, I don't know," admitted Linane. "But I do know that you don't like me to tell you anything. Nevertheless, I am going to tell you that you had better get busy and find out what caused it, or—"

"That's just what I'm doing," said Jenks, and he dived for his plans on the floor.

Newspaper reporters, many of them, were fighting outside to get in. Muller looked at Linane when a stenographer had announced the reporters for the tenth time.

"We had better let them in," he said, "it looks bad to crawl for cover."

"What are you going to tell them?" asked Linane.

"God only knows," said Muller.

"Let me handle them," said Jenks, looking up confidently.

* * * * *

The newspapermen had rushed the office. They came in like a wild wave. Questions flew like feathers at a cock-fight.

Muller held up his hand and there was something in his grief-stricken eyes that held the gentlemen of the press in silence. They had time to look around. They saw the handsome, dark-haired, brown-eyed Jenks poring over the plans. Dust from the carpet smudged his knees, and he had rubbed some of it over a sweating forehead, but he still looked the picture of self-confident efficiency.

"Gentlemen," said Muller slowly, "I can answer all your questions at once. Our firm is one of the oldest and staunchest in the trade. Our buildings stand as monuments to our integrity—"

"All but one," said a young Irishman.

"You are right. All but one," confessed Muller. "But that one, believe me, has been visited by an act of God. Some form of earthquake or some unlooked for, uncontrolled, almost unbelievable catastrophe has happened. The Muller company stands back of its work to its last dollar. Gentlemen, you know as much as we do. Mr. Jenks there, whose reputation as an engineer is quite sturdy, I assure you, was the last to inspect the building. He passed upon it when it was finished. He is at your service."

Jenks arose, brushed some dust from his knees.

"You look like you'd been praying," bandied the Irishman.

"Maybe I have. Now let me talk. Don't broadside me with questions. I know what you want to know. Let me talk."

The newspapermen were silent.

"There has been talk of probing this disaster, naturally," began Jenks. "You all know, gentlemen, that we will aid any inquiry to our utmost. You want to know what we have to say about it—who is responsible. In a reasonable time I will have a statement to make that will be startling in the extreme. I am not sure of my ground now."

"How about the ground under the Colossus?" said the Irishman.

"Don't let's kid each other," pleaded Jenks. "Look at Mr. Muller: it is as if he had lost his whole family. We are good people. I am doing all I can. Mr. Linane, who had charge of the construction, is doing all he can. We believe we are blameless. If it is proven otherwise we will acknowledge our fault, assume financial responsibility, and take our medicine. Believe me, that building was perfection plus, like all our buildings. That covers the entire situation."

Hundreds of questions were parried and answered by the three engineers, and the reporters left convinced that if the Muller Construction Company was responsible, it was not through any fault of its own.

* * * * *

The fact that Jenks and Linane were not strong for each other, except to recognize each other's ability as engineers, was due to an incident of the past. This incident had caused a ripple of mirth in engineering circles when it happened, and the laugh was on the older man, Linane.

It was when radio was new. Linane, a structural engineer, had paid little attention to radio. Jenks was the kind of an engineer who dabbled in all sciences. He knew his radio.

When Jenks first came to work with a technical sheepskin and a few tons of brass, Linane accorded him only passing notice. Jenks craved the plaudits of the older man and his palship. Linane treated him as a son, but did not warm to his social advances.

"I'm as good an engineer as he is," mused Jenks, "and if he is going to high-hat me, I'll just put a swift one over on him and compel his notice."

The next day Jenks approached Linane in conference and said:

"I've got a curious bet on, Mr. Linane. I am betting sound can travel a mile quicker than it travels a quarter of a mile."

"What?" said Linane.

"I'm betting fifty that sound can travel a mile quicker than it can travel a quarter of a mile."

"Oh no—it can't," insisted Linane.

"Oh yes—it can!" decided Jenks.

"I'll take some of that fool money myself," said Linane.

"How much?" asked Jenks.

"As much as you want."

"All right—five hundred dollars."

"How you going to prove your contention?"

"By stop watches, and your men can hold the watches. We'll bet that a pistol shot can be heard two miles away quicker than it can be heard a quarter of a mile away."

"Sound travels about a fifth of a mile a second. The rate varies slightly according to temperature," explained Linane. "At the freezing point the rate is 1,090 feet per second and increases a little over one foot for every degree Fahrenheit."

"Hot or cold," breezed Jenks, "I am betting you five hundred dollars that sound can travel two miles quicker than a quarter-mile."

"You're on, you damned idiot!" shouted the completely exasperated Linane.

* * * * *

Jenks let Linane's friends hold the watches and his friend held the money. Jenks was to fire the shot.

Jenks fired the shot in front of a microphone on a football field. One of Linane's friends picked the sound up instantaneously on a three-tube radio set two miles away. The other watch holder was standing in the open a quarter of a mile away and his watch showed a second and a fraction.

All hands agreed that Jenks had won the bet fairly. Linane never exactly liked Jenks after that.

Then Jenks rather aggravated matters by a habit. Whenever Linane would make a very positive statement Jenks would look owl-eyed and say: "Mr. Linane, I'll have to sound you out about that." The heavy accent on the word "sound" nettled Linane somewhat.

Linane never completely forgave Jenks for putting over this "fast one." Socially they were always more or less at loggerheads, but neither let this feeling interfere with their work. They worked together faithfully enough and each recognized the ability of the other.

And so it was that Linane and Jenks, their heads together, worked all night in an attempt to find some cause that would tie responsibility for the disaster on mother nature.

They failed to find it and, sleepy-eyed, they were forced to admit failure, so far.

The newspapers, to whom Muller had said that he would not shirk any responsibility, began a hue and cry for the arrest of all parties in any way concerned with the direction of the building of the Colossus.

When the death list from the crash and subway wreck reached 97, the press waxed nasty and demanded the arrest of Muller, Linane and Jenks in no uncertain tones.

Half dead from lack of sleep, the three men were taken by the police to the district attorney's offices and, after a strenuous grilling, were formally placed under arrest on charges of criminal negligence. They put up a $50,000 bond in each case and were permitted to go and seek further to find the cause of what the newspapers now began calling the "Colossal Failure."

Several days were spent by Linane and Jenks in examining the wreckage which was being removed from Times Square, truckload after truckload, to a point outside the city. Here it was again sorted and examined and piled for future disposal.

So far as could be found every brick, stone and ounce of material used in the building was perfect. Attorneys, however, assured Linane, Jenks and Muller that they would have to find the real cause of the disaster if they were to escape possible long prison sentences.

Night after night Jenks courted sleep, but it would not come. He began to grow wan and haggard.

* * * * *

Jenks took to walking the streets at night, mile after mile, thinking, always thinking, and searching his mind for a solution of the mystery.

It was evening. He had walked past the scene of the Colossus crash several times. He found himself on a side street. He looked up and saw in electric lights:

TOWN HALL

Munsterbergen, the Mad Musician Concert Here To-night.

He took five dollars from his pocket and bought a ticket. He entered with the crowd and was ushered to a seat. He looked neither to the right or left. His eyes were sunken, his face lined with worry.

Something within Jenks caused him to turn slightly. He was curiously aware of a beautiful girl who sat beside him. She had a mass of golden hair which seemed to defy control. It was wild, positively tempestuous. Her eyes were deep blue and her skin as white as fleecy clouds in spring. He was dimly conscious that those glorious eyes were troubled.

She glanced at him. She was aware that he was suffering. A great surge of sympathy welled in her heart. She could not explain the feeling.

A great red plush curtain parted in the center and drew in graceful folds to the edges of the proscenium. A small stage was revealed.

A tousle-headed man with glaring, beady black eyes, dressed in black evening clothes stepped forward and bowed. Under his arm was a violin. He brought the violin forward. His nose, like the beak of some great bird, bobbed up and down in acknowledgment of the plaudits which greeted him. His long nervous fingers began to caress the instrument and his lips began to move.

Jenks was aware that he was saying something, but was not at all interested. What he said was this:

"Maybe, yes, I couldn't talk so good English, but you could understood it, yes? Und now I tell you dot I never play the compositions of any man. I axtemporize exgloosively. I chust blay und blay, und maybe you should listen, yes? If I bleeze you I am chust happy."

Jenks' attention was drawn to him. He noted his wild appearance.

"He sure looks mad enough," mused Jenks.

* * * * *

The violinist flipped the fiddle up under his chin. He drew the bow over the strings and began a gentle melody that reminded one of rain drops falling on calm waters.

Jenks forgot his troubles. He forgot everything. He slumped in his seat and his eyes closed. The rain continued falling from the strings of the violin.

Suddenly the melody changed to a glad little lilting measure, as sweet as love itself. The sun was coming out again and the birds began to sing. There was the trill of a canary with the sun on its cage. There was the song of the thrush, the mocking-bird and the meadow lark. These blended finally into a melodious burst of chirping melody which seemed a chorus of the wild birds of the forest and glen. Then the lilting love measure again. It tore at the heart strings, and brought tears to one's eyes.

Unconsciously the girl next to Jenks leaned towards him. Involuntarily he leaned to meet her. Their shoulders touched. The cloud of her golden hair came to rest against his dark locks. Their hands found each other with gentle pressure. Both were lost to the world.

Abruptly the music changed. There was a succession of broken treble notes that sounded like the crackling of flames. Moans deep and melancholy followed. These grew more strident and prolonged, giving place to abject howls, suggesting the lamentations of the damned.

The hands of the boy and girl gripped tensely. They could not help shuddering.

The violin began to produce notes of a leering, jeering character, growing more horrible with each measure until they burst in a loud guffaw of maniacal laughter.

The whole performance was as if someone had taken a heaven and plunged it into a hell.

The musician bowed jerkily, and was gone.

* * * * *

There was no applause, only wild exclamations. Half the house was on its feet. The other half sat as if glued to chairs.

The boy and the girl were standing, their hands still gripping tensely.

"Come, let's get out of here," said Jenks. The girl took her wrap and Jenks helped her into it. Hand in hand they fled the place.

In the lobby their eyes met, and for the first time they realized they were strangers. Yet deep in their hearts was a feeling that their fates had been sealed.

"My goodness!" burst from the girl.

"It can't be helped now," said Jenks decisively.

"What can't be helped?" asked the girl, although she knew in her heart.

"Nothing can be helped," said Jenks. Then he added: "We should know each other by this time. We have been holding hands for an hour."

The girl's eyes flared. "You have no right to presume on that situation," she said.

Jenks could have kicked himself. "Forgive me," he said. "It was only that I just wanted so to know you. Won't you let me see you home?"

"You may," said the girl simply, and she led the way to her own car.

They drove north.

Their bodies seemed like magnets. They were again shoulder to shoulder, holding hands.

"Will you tell me your name?" pleaded Jenks.

"Surely," replied the girl. "I am Elaine Linane."

"What?" exploded Jenks. "Why, I work with a Linane, an engineer with the Muller Construction Company."

"He is my father," she said.

"Why, we are great friends," said the boy. "I am Jenks, his assistant—at least we work together."

"Yes, I have heard of you," said the girl. "It is strange, the way we met. My father admires your work, but I am afraid you are not great friends." The girl had forgotten her troubles. She chuckled. She had heard the way Jenks had "sounded" her father out.

Jenks was speechless. The girl continued:

"I don't know whether to like you or to hate you. My father is an old dear. You were cruel to him."

Jenks was abject. "I did not mean to be," he said. "He rather belittled me without realizing it. I had to make my stand. The difference in our years made him take me rather too lightly. I had to compel his notice, if I was to advance."

"Oh!" said the girl.

"I am sorry—so sorry."

"You might not have been altogether at fault," said the girl. "Father forgets at times that I have grown up. I resent being treated like a child, but he is the soul of goodness and fatherly care."

"I know that," said Jenks.

* * * * *

Every engineer knows his mathematics. It was this fact, coupled with what the world calls a "lucky break," that solved the Colossus mystery. Nobody can get around the fact that two and two make four.

Jenks had happened on accomplishment to advance in the engineering profession, and it was well for him that he had reached a crisis. He had never believed in luck or in hunches, so it was good for him to be brought face to face with the fact that sometimes the footsteps of man are guided. It made him begin to look into the engineering of the universe, to think more deeply, and to acknowledge a Higher Power.

With Linane he had butted into a stone wall. They were coming to know what real trouble meant. The fact that they were innocent did not make the steel bars of a cage any more attractive. Their troubles began to wrap about them with the clammy intimacy of a shroud. Then came the lucky break.

Next to his troubles, Jenks' favorite topic was the Mad Musician. He tried to learn all he could about this uncanny character at whose concert he had met the girl of his life. He learned two facts that made him perk up and think.

One was that the Mad Musician had had offices and a studio in the Colossus and was one of the first to move in. The other was that the Mad Musician took great delight in shattering glassware with notes of or vibrations from a violin. Nearly everyone knows that a glass tumbler can be shattered by the proper note sounded on a violin. The Mad Musician took delight in this trick. Jenks courted his acquaintance, and saw him shatter a row of glasses of different sizes by sounding different notes on his fiddle. The glasses crashed one after another like gelatine balls hit by the bullets of an expert rifleman.

Then Jenks, the engineer who knew his mathematics, put two and two together. It made four, of course.

"Listen, Linane," he said to his co-worker: "this fiddler is crazier than a flock of cuckoos. If he can crack crockery with violin sound vibrations, is it not possible, by carrying the vibrations to a much higher power, that he could crack a pile of stone, steel, brick and cement, like the Colossus?"

"Possible, but hardly probable. Still," Linane mused, "when you think about it, and put two and two together.... Let's go after him and see what he is doing now."

Both jumped for their coats and hats. As they fared forth, Jenks cinched his argument:

"If a madman takes delight in breaking glassware with a vibratory wave or vibration, how much more of a thrill would he get by crashing a mountain?"

"Wild, but unanswerable," said Linane.

* * * * *

Jenks had been calling on the Mad Musician at his country place. "He had a studio in the Colossus," he reminded Linane. "He must have re-opened somewhere else in town. I wonder where."

"Musicians are great union men," said Linane. "Phone the union."

Teddy Jenks did, but the union gave the last known town address as the Colossus.

"He would remain in the same district around Times Square," reasoned Jenks. "Let's page out the big buildings and see if he is not preparing to crash another one."

"Fair enough," said Linane, who was too busy with the problem at hand to choose his words.

Together the engineers started a canvass of the big buildings in the theatrical district. After four or five had been searched without result they entered the 30-story Acme Theater building.

Here they learned that the Mad Musician had leased a four-room suite just a few days before. This suite was on the fifteenth floor, just half way up in the big structure.

They went to the manager of the building and frankly stated their suspicions. "We want to enter that suite when the tenant is not there," they explained, "and we want him forestalled from entering while we are examining the premises."

"Hadn't we better notify the police?" asked the building manager, who had broken out in a sweat when he heard the dire disaster which might be in store for the stately Acme building.

"Not yet," said Linane. "You see, we are not sure: we have just been putting two and two together."

"We'll get the building detective, anyway," insisted the manager.

"Let him come along, but do not let him know until we are sure. If we are right we will find a most unusual infernal machine," said Linane.

* * * * *

The three men entered the suite with a pass-key. The detective was left outside in the hall to halt anyone who might disturb the searchers. It was as Jenks had thought. In an inner room they found a diabolical machine—a single string stretched across two bridges, one of brass and one of wood. A big horsehair bow attached to a shaft operated by a motor was automatically sawing across the string. The note resulting was evidently higher than the range of the human ear, because no audible sound resulted. It was later estimated that the destructive note was several octaves higher than the highest note on a piano.

The entire machine was enclosed in a heavy wire-net cage, securely bolted to the floor. Neither the string or bow could be reached. It was evidently the Mad Musician's idea that the devilish contrivance should not be reached by hands other than his own.

How long the infernal machine had been operating no one knew, but the visitors were startled when the building suddenly began to sway perceptibly. Jenks jumped forward to stop the machine but could not find a switch.

"See if the machine plugs in anywhere in a wall socket!" he shouted to Linane, who promptly began examining the walls. Jenks shouted to the building manager to phone the police to clear the streets around the big building.

"Tell the police that the Acme Theater building may crash at any moment," he instructed.

The engineers were perfectly cool in face of the great peril, but the building manager lost his head completely and began to run around in circles muttering: "Oh, my God, save me!" and other words of supplication that blended into an incoherent babel.

Jenks rushed to the man, trying to still his wild hysteria.

The building continued to sway dangerously.

* * * * *

Jenks looked from a window. An enormous crowd was collecting, watching the big building swinging a foot out of plumb like a giant pendulum. The crowd was growing. Should the building fall the loss of life would be appalling. It was mid-morning. The interior of the building teemed with thousands of workers, for all floors above the third were offices.

Teddy Jenks turned suddenly. He heard the watchman in the hall scream in terror. Then he heard a body fall. He rushed to the door to see the Mad Musician standing over the prostrate form of the detective, a devilish grin on his distorted countenance.

The madman turned, saw Jenks, and started to run. Jenks took after him. Up the staircase the madman rushed toward the roof. Teddy followed him two floors and then rushed out to take the elevators. The building in its mad swaying had made it impossible for the lifts to be operated. Teddy realized this with a distraught gulp in his throat. He returned to the stairway and took up the pursuit of the madman.

The corridors were beginning to fill with screaming men and wailing girls. It was a sight never to be forgotten.

Laboriously Jenks climbed story after story without getting sight of the madman. Finally he reached the roof. It was waving like swells on a lake before a breeze. He caught sight of the Mad Musician standing on the street wall, thirty stories from the street, a leer on his devilish visage. He jumped for him.

The madman grasped him and lifted him up to the top of the wall as a cat might have lifted a mouse. Both men were breathing heavily as a result of their 15-story climb.

The madman tried to throw Teddy Jenks to the street below. Teddy clung to him. The two battled desperately as the building swayed.

The dense crowd in the street had caught sight of the two men fighting on the narrow coping, and the shout which rent the air reached the ears of Jenks.

* * * * *

The mind of the engineer was still working clearly, but a wild fear gripped his heart. His strength seemed to be leaving him. The madman pushed him back, bending his spine with brute strength. Teddy was forced to the narrow ledge that had given the two men footing. The fingers of the madman gripped his throat.

He was dimly conscious that the swaying of the building was slowing down. His reason told him that Linane had found the wall socket and had stopped the sawing of the devil's bow on the engine of hell.

He saw the madman draw a big knife. With his last remaining strength he reached out and grasped the wrist above the hand which held the weapon. In spite of all he could do he saw the madman inching the knife nearer and nearer his throat.

Grim death was peering into the bulging eyes of Teddy Jenks, when his engineering knowledge came to his rescue. He remembered the top stories of the Acme building were constructed with a step of ten feet in from the street line, for every story of construction above the 24th floor.

"If we fall," he reasoned, "we can only fall one story." Then he deliberately rolled his own body and the weight of the madman, who held him, over the edge of the coping. At the same time he twisted the madman's wrist so the point of the knife pointed to the madman's body.

There was a dim consciousness of a painful impact. Teddy had fallen underneath, but the force of the two bodies coming together had thrust the knife deep into the entrails of the Mad Musician.

Clouds which had been collecting in the sky began a splattering downpour. The storm grew in fury and lightning tore the heavens, while thunder boomed and crackled. The rain began falling in sheets.

* * * * *

This served to revive the unconscious Teddy. He painfully withdrew his body from under that of the madman. The falling rain, stained with the blood of the Mad Musician, trickled over the edge of the building.

Teddy dragged himself through a window and passed his hand over his forehead, which was aching miserably. He tried to get to his feet and fell back, only to try again. Several times he tried and then, his strength returning, he was able to walk.

He made his way to the studio where he had left Linane and found him there surrounded by police, reporters and others. The infernal machine had been rendered harmless, but was kept intact as evidence.

Catching sight of Teddy, Linane shouted with joy. "I stopped the damned thing," he chuckled, like a pleased schoolboy. Then, observing Teddy's exhausted condition he added:

"Why, you look like you have been to a funeral!"

"I have," said Teddy. "You'll find that crazy fiddler dead on the twenty-ninth story. Look out the window of the thirtieth story," he instructed the police, who had started to recover the body. "He stabbed himself. He is either dead or dying."

It proved that he was dead.

No engineering firm is responsible for the actions of a madman. So the Muller Construction Company was given a clean bill of health.

* * * * *

Jenks and Elaine Linane were with the girl's father in his study. They were asking for the paternal blessing.

Linane was pretending to be hard to convince.

"Now, my daughter," he said, "this young man takes $500 of my good money by sounding me out, as he calls it. Then he comes along and tries to take my daughter away from me. It is positively high-handed. It dates back to the football game—"

"Daddy, dear, don't be like that!" said Elaine, who was on the arm of his chair with her own arms around him.

"I tell you, Elaine, this dates back to the fall of 1927."

"It dates back to the fall of Eve," said Elaine. "When a girl finds her man, no power can keep him from her. If you won't give me to Teddy Jenks, I'll elope with him."

"Well, all right then. Kiss me," said Linane as he turned towards his radio set.

"One and one makes one," said Teddy Jenks.

Every engineer knows his mathematics.

The Thief of Time

By Captain S. P. Meek

The teller turned to the stacked pile of bills. They were gone! And no one had been near!



Harvey Winston, paying teller of the First National Bank of Chicago, stripped the band from a bundle of twenty dollar bills, counted out seventeen of them and added them to the pile on the counter before him.

"Twelve hundred and thirty-one tens," he read from the payroll change slip before him. The paymaster of the Cramer Packing Company nodded an assent and Winston turned to the stacked bills in his rear currency rack. He picked up a handful of bundles and turned back to the grill. His gaze swept the counter where, a moment before, he had stacked the twenties, and his jaw dropped.

"You got those twenties, Mr. Trier?" he asked.

"Got them? Of course not, how could I?" replied the paymaster. "There they are...."

His voice trailed off into nothingness as he looked at the empty counter.

"I must have dropped them," said Winston as he turned. He glanced back at the rear rack where his main stock of currency was piled. He stood paralyzed for a moment and then reached under the counter and pushed a button.

The bank resounded instantly to the clangor of gongs and huge steel grills shot into place with a clang, sealing all doors and preventing anyone from entering or leaving the bank. The guards sprang to their stations with drawn weapons and from the inner offices the bank officials came swarming out. The cashier, followed by two men, hurried to the paying teller's cage.

"What is it, Mr. Winston?" he cried.

"I've been robbed!" gasped the teller.

"Who by? How?" demanded the cashier.

"I—I don't know, sir," stammered the teller. "I was counting out Mr. Trier's payroll, and after I had stacked the twenties I turned to get the tens. When I turned back the twenties were gone."

"Where had they gone?" asked the cashier.

"I don't know, sir. Mr. Trier was as surprised as I was, and then I turned back, thinking that I had knocked them off the counter, and I saw at a glance that there was a big hole in my back racks. You can see yourself, sir."

The cashier turned to the paymaster.

"Is this a practical joke, Mr. Trier?" he demanded sharply.

"Of course not," replied the paymaster. "Winston's grill was closed. It still is. Granted that I might have reached the twenties he had piled up, how could I have gone through a grill and taken the rest of the missing money without his seeing me? The money disappeared almost instantly. It was there a moment before, for I noticed when Winston took the twenties from his rack that it was full."

"But someone must have taken it," said the bewildered cashier. "Money doesn't walk off of its own accord or vanish into thin air—"

A bell interrupted his speech.

"There are the police," he said with an air of relief. "I'll let them in."

* * * * *

The smaller of the two men who had followed the cashier from his office when the alarm had sounded stepped forward and spoke quietly. His voice was low and well pitched yet it carried a note of authority and power that held his auditors' attention while he spoke. The voice harmonized with the man. The most noticeable point about him was the inconspicuousness of his voice and manner, yet there was a glint of steel in his gray eyes that told of enormous force in him.

"I don't believe that I would let them in for a few moments, Mr. Rogers," he said. "I think that we are up against something a little different from the usual bank robbery."

"But, Mr. Carnes," protested the cashier, "we must call in the police in a case like this, and the sooner they take charge the better chance there will be of apprehending the thief."

"Suit yourself," replied the little man with a shrug of his shoulders. "I merely offered my advice."

"Will you take charge, Mr. Carnes?" asked the cashier.

"I can't supersede the local authorities in a case like this," replied Carnes. "The secret service is primarily interested in the suppression of counterfeiting and the enforcement of certain federal statutes, but I will be glad to assist the local authorities to the best of my ability, provided they desire my help. My advice to you would be to keep out the patrolmen who are demanding admittance and get in touch with the chief of police. I would ask that his best detective together with an expert finger-print photographer be sent here before anyone else is admitted. If the patrolmen are allowed to wipe their hands over Mr. Winston's counter they may destroy valuable evidence."

"You are right, Mr. Carnes," exclaimed the cashier. "Mr. Jervis, will you tell the police that there is no violence threatening and ask them to wait for a few minutes? I'll telephone the chief of police at once."

* * * * *

As the cashier hurried away to his telephone Carnes turned to his companion who had stood an interested, although silent spectator of the scene. His companion was a marked contrast to the secret service operator. He stood well over six feet in height, and his protruding jaw and shock of unruly black hair combined with his massive shoulders and chest to give him the appearance of a man who labored with his hands—until one looked at them. His hands were in strange contrast to the rest of him. Long, slim, mobile hands they were, with tapering nervous fingers—the hands of a thinker or of a musician. Telltale splotches of acid told of hours spent in a laboratory, a tale that was confirmed by the almost imperceptible stoop of his shoulders.

"Do you agree with my advice, Dr. Bird?" asked Carnes deferentially.

The noted scientist, who from his laboratory in the Bureau of Standards had sent forth many new things in the realms of chemistry and physics, and who, incidentally, had been instrumental in solving some of the most baffling mysteries which the secret service had been called upon to face, grunted.

"It didn't do any harm," he said, "but it is rather a waste of time. The thief wore gloves."

"How in thunder do you know that?" demanded Carnes.

"It's merely common sense. A man who can do what he did had at least some rudiments of intelligence, and even the feeblest-minded crooks know enough to wear gloves nowadays."

Carnes stepped a little closer to the doctor.

"Another reason why I didn't want patrolmen tramping around," he said in an undertone, "is this. If Winston gave the alarm quickly enough, the thief is probably still in the building."

"He's a good many miles away by now," replied Dr. Bird with a shrug of his shoulders.

* * * * *

Carnes' eyes opened widely. "Why?—how?—who?" he stammered. "Have you any idea of who did it, or how it was done?"

"Possibly I have an idea," replied Dr. Bird with a cryptic smile. "My advice to you, Carnes, is to keep away from the local authorities as much as possible. I want to be present when Winston and Trier are questioned and I may possibly wish to ask a few questions myself. Use your authority that far, but no farther. Don't volunteer any information and especially don't let my name get out. We'll drop the counterfeiting case we were summoned here on for the present and look into this a little on our own hook. I will want your aid, so don't get tied up with the police."

"At that, we don't want the police crossing our trail at every turn," protested Carnes.

"They won't," promised the doctor. "They will never get any evidence on this case, if I am right, and neither will we—for the present. Our stunt is to lie low and wait for the next attempt of this nature and thus accumulate some evidence and some idea of where to look."

"Will there be another attempt?" asked Carnes.

"Surely. You don't expect a man who got away with a crime like this to quit operations just because a few flatfeet run around and make a hullabaloo about it, do you? I may be wrong in my assumption, but if I am right, the most important thing is to keep all reference to my name or position out of the press reports."

The cashier hastened up to them.

"Detective-Captain Sturtevant will be here in a few minutes with a photographer and some other men," he said. "Is there anything that we can do in the meantime, Mr. Carnes?"

"I would suggest that Mr. Trier and his guard and Mr. Winston go into your office," replied Carnes. "My assistant and I would like to be present during the questioning, if there are no objections."

"I didn't know that you had an assistant with you," answered the cashier.

Carnes indicated Dr. Bird.

"This gentleman is Mr. Berger, my assistant," he said. "Do you understand?"

"Certainly. I am sure there will be no objection to your presence, Mr. Carnes," replied the cashier as he led the way to his office.

* * * * *

A few minutes later Detective-Captain Sturtevant of the Chicago police was announced. He acknowledged the introductions gruffly and got down to business at once.

"What were the circumstances of the robbery?" he asked.

Winston told his story, Trier and the guard confirming it.

"Pretty thin!" snorted the detective when they had finished. He whirled suddenly on Winston.

"Where did you hide the loot?" he thundered.

"Why—uh—er—what do you mean?" gulped the teller.

"Just what I said," replied the detective. "Where did you hide the loot?"

"I didn't hide it anywhere," said the teller. "It was stolen."

"You had better think up a better one," sneered Sturtevant. "If you think that you can make me believe that that money was stolen from you in broad daylight with two men in plain sight of you who didn't see it, you might just as well get over it. I know that you have some hiding place where you have slipped the stuff and the quicker you come clean and spill it, the better it will be for you. Where did you hide it?"

"I didn't hide it!" cried the teller, his voice trembling. "Mr. Trier can tell you that I didn't touch it from the time I laid it down until I turned back."

"That's right," replied the paymaster. "He turned his back on me for a moment, and when he turned back, it was gone."

"So you're in on it too, are you?" said Sturtevant.

"What do you mean?" demanded the paymaster hotly.

"Oh nothing, nothing at all," replied the detective. "Of course Winston didn't touch it and it disappeared and you never saw it go, although you were within three feet of it all the time. Did you see anything?" he demanded of the guard.

"Nothing that I am sure of," answered the guard. "I thought that a shadow passed in front of me for an instant, but when I looked again, it was gone."

* * * * *

Dr. Bird sat forward suddenly. "What did this shadow look like?" he asked.

"It wasn't exactly a shadow," said the guard. "It was as if a person had passed suddenly before me so quickly that I couldn't see him. I seemed to feel that there was someone there, but I didn't rightly see anything."

"Did you notice anything of the sort?" demanded the doctor of Trier.

"I don't know," replied Trier thoughtfully. "Now that Williams has mentioned it, I did seem to feel a breath of air or a motion as though something had passed in front of me. I didn't think of it at the time."
