CHAPTER XII

_Mysterious Little Golden Rock_

I need not detail the aftermath of our emergence from the atom. Dr.

Kent and Babs followed me out within a few moments. But Alan was not

with them! He had seen Polter fall. His father and Babs were safe. The

sacrifice he had made in leaving Glora was no longer needed.

Down there on the rocky plateau, Dr. Kent suddenly realized that Alan

was dwindling.

"Father, I must! Don't you understand? Glora's world is menaced. I

can't leave her like this. My duty to you and Babs is ended. I did my

best, Dad--you two are safe now."

"Alan! My boy!"

He was already down at Dr. Kent's waist, Bab's size. He held up his

hand. "Dad, good-by." His rugged, youthful face was flushed, his voice

choked. "You--you've been a mighty good father to me. Always."

Babs flung her arms about him. "Alan, don't!"

"But I must." He smiled whimsically as he kissed her. "You wouldn't

want to leave George, would you? Never see him again? I'm not asking

you to do that, am I?"

"But, Alan--"

"You've been a great little pal, Babs. I'll never forget it."

"Alan! You talk as though you were never coming back!"

"Do I? But of course I'm coming back!" He cast her off. "Babs, listen.

Father's upset. That's natural. You tell him not to worry. I'll be

careful, and do what I can to save that little city. I must find Glora

and--"

Babs was suddenly trembling with eagerness for him. "Yes! Of course

you must, Alan!"

"Find her and bring her out here! I'll do it! Don't you worry." He was

dwindling fast. Dr. Kent had collapsed to a rock, staring down with

horror-stricken eyes. Alan called up to Babs:

"Listen! Have George watch the chunk of gold-quartz. Have it guarded

and watched day and night. Handle it carefully, Babs!"

"Yes! Yes! How long will you be gone, Alan?"

"Heavens--how do I know? But I'll come back, don't you worry. Maybe in

only a day or two of your time."

"Right! Good-by, Alan!"

"Good-by," his tiny voice echoed up. "Good-by, Babs--Father!"

Babs could see his miniature face smiling up at her. She smiled back

and waved her arm as he vanished into the pebbles at her feet.

The eyes of youth! They look ahead; they see all things so easily

possible! But old Dr. Kent was sobbing.

* * * * *

It has broken Dr. Kent. A month now has passed. He seldom mentions

Alan to Babs and me. But when he does, he tries to smile and say that

Alan soon will return. He has been very ill this last week, though he

is better now. He did not tell us that he was working to compound

another supply of the drugs, but we knew it very well.

And his emotion, the strain of it, made him break. He was in bed a

week. We are living in New York, quite near the Museum of the American

Society for Scientific Research. In a room of the biological

department there, the precious fragment of golden quartz lies guarded.

A microscope is over it, and there is never a moment of the day or

night without an alert, keen-eyed watcher peering down.

But nothing has appeared. Neither friend nor foe--nothing. I cannot

say so to Babs, but often I fear that Dr. Kent will suddenly die, and

the secret of his drugs die with him. I hinted once that I would make

a trip into the atom if he would let me, but it excited him so greatly

I had to laugh it off with the assurance that of course Alan will soon

return safely to us. Dr. Kent is an old man now, unnaturally old,

with, it seems, the full weight of eighty years pressing upon him. He

cannot stand this emotion. I think he is despairingly summoning

strength to work upon his drugs, fearful that he will not be equal to

it. Yet more fearful to disclose the secret and unloose so diabolical

a power.

There are nights when with Dr. Kent asleep, Babs and I slip away and

go to the Museum. We dismiss the guard for a time, and in that private

room we sit hand in hand by the microscope to watch. The fragment of

golden quartz lies on its clean white slab with a brilliant light upon

it.

Mysterious little golden rock! What secrets are there, down beyond the

vanishing point in the realm of the infinitely small! Our human

longings go to Alan and to Glora.

But sometimes we are swept by the greater viewpoint. Awed by the

mysteries of nature, we realize how very small and unimportant we are

in the vast scheme of things. We envisage the infinite reaches of

astronomical space overhead. Realms of largeness unfathomable. And at

our feet, everywhere, are myriad entrances into the infinitely small.

With ourselves in between--with our fatuous human consciousness that

we are of some importance to it all!

Truly there are more things in Heaven and Earth than are dreamed of in

our philosophy!

INVISIBLE EYES

An invisible eye that can see in the dark and detect the light of a

ship two miles away on a black foggy night was introduced to newspaper

men recently by its inventor, John Baird of television fame. He calls

the invention "Noctovisor."

It looks like a large camera and can be mounted on a ship or airplane.

It was announced that it would soon be tried on trans-Atlantic liners.

For the demonstration it was mounted in the garden of Baird's cottage,

overlooking the twinkling lights of Dorking. In the dark beyond those

lights an automobile headlight three miles away pointed toward the

cottage.

At a signal from the inventor a sheet of ebonite, as a substitute for

a supposed fog, two miles thick, was placed in front of the headlight.

Not a glimmer was then visible to the human eye, but it appeared on

the noctovisor screen as a bright red disc. It was supposed to have

particular value in permitting a navigator in a fog to tell the exact

direction of a beacon and to estimate roughly its distance.

The device is a combination of camera lens, television transmitter and

television receiver. The lens throws a distant image on the exploring

disc of the transmitter, through which it acts on a photo-electric

cell sensitive to invisible infra-red rays. The receiver amplifies it

for the observer.

MOON ROCKETS

Seventeen years of experimenting on a rocket designed by Prof. Albert

H. Goddard of Clark University, to shriek its way from the earth to

the moon, came to a glorious climax recently in an isolated and

closely guarded section of Worcester when the rocket tore its flaming

way through the air for a quarter-mile with a roar heard for a

distance of two miles.

Prof. Goddard said the rocket was shot out of its cradle, careened

through the air a mass of flame, and landed about where it was

directed to land, beyond the Auburn town line. Test of a new

propellant was the object of his demonstration, Prof. Goddard said.

Two or three times a week a small rocket goes up into the air a short

distance, not enough to attract great attention. But the latest was a

nine-foot rocket, shot out of a forty-foot tower. Near the tower is a

safety post built of stone, with slits for peepholes. The experimental

party stepped into the safety zone when the rocket was started.

The forty-foot tower is built much like an oil well derrick. Inside it

are two steel rails to fill grooves in the rocket. These guide the

rocket much as rifling in a gun barrel guides a bullet. Prof. Goddard,

when teaching at Princeton in 1912, evolved the idea of shooting a

rocket to the moon by means of successive charges of explosive much as

the new German rocket motor racers are powered. In this most recent

experiment he used a new powder mixture.

Prof. Goddard issued a statement after the demonstration, which said:

"My test was one of a series of experiments with rockets using an

entirely new propellant. There was no attempt to reach the moon or

anything of such a spectacular nature. The rocket is normally noisy,

possibly enough to attract considerable attention. The test was

thoroughly satisfactory, nothing exploded in the air, and there was no

damage except possibly that incidental to landing."

Terrors Unseen

_By Harl Vincent_

[Illustration: _"Eddie!" Lisa screamed suddenly. "Look out!"_]

[Sidenote: One after another the invisible robots escape Shelton's

control--and their trail leads straight to the gangster chief

Cadorna.]

Something about the lonely figure of the girl caused Edward Vail to

bring his car to a sudden stop at the side of the road. When first he

had glimpsed her off there on that narrow strip of rock-bound coast he

was mildly surprised, for it was a desolate spot and seldom frequented

by bathers so late in the season. Now he was aroused to startled

attention by the unnatural posture of the slender body that had just

been erect and outlined sharply against the graying September sky. He

switched off the ignition and sprang to the ground.

Bent backward and twisted into the attitude of a contortionist, the

little figure in the crimson bathing suit was a thing at which to

marvel. No human being could maintain that position without falling,

yet the girl did not fall to the jagged stones that lay beneath her.

She was rigid, straining. Then suddenly her arm waved wildly and she

screamed, a wild gasping cry that died in her throat on a note of

despairing terror. It seemed that she struggled furiously with an

unseen power for one horrible instant. Then the tortured body lurched

violently and collapsed in a pitiful quivering heap among the stones.

Eddie Vail was running now, miraculously picking his way over the

treacherous footing. The girl had fainted, no doubt of that, and

something was seriously wrong with her.

A mysterious mechanical something whizzed past; something that buzzed

like a thousand hornets and slithered over the rocks in a series of

metallic clanks. Then it was gone--or so it seemed in the confusion of

Eddie's mind; but he had seen nothing. Probably a fantasy of his

overworked brain, or only the surf breaking against the sea wall. He

turned his attention to the girl.

* * * * *

She was moaning and tossing her head, returning painfully to

consciousness. He straightened her limbs and placed his folded coat

under the restless head, noting with alarm that vicious red welts

marred the whiteness of her arms and shoulders. It was as if she had

been beaten cruelly; those marks could never have resulted from her

fall. Poor kid. Subject to fits of some sort, he presumed. She was a

good looker, too, and no mistake. He smoothed back the rumpled mass of

golden hair and studied her features. They were vaguely familiar.

Then she opened her eyes. Stark terror looked out from their

ultra-marine depths, and her lips quivered as if she were about to

cry. He raised her to a more comfortable position and supported her

with an encircling arm. She did cry a little, like a frightened child.

Then, with startling abruptness, she sprang to her feet.

"Where is it?" she demanded.

"Where's what?" Eddie was on his feet, peering in all directions. He

remembered the queer sounds he had heard or imagined.

"I--I don't know." The girl passed a trembling hand before her eyes as

if to wipe away some horrifying vision. "Perhaps it's my imagination,

but I felt--it was just as real--one of father's iron monsters.

Beating me; bending me. I'd have snapped in a moment. But nothing was

there. I--I'm afraid...."

Eddie caught her as she swayed on her feet. "There now," he said

soothingly, "you're all right, Miss Shelton. It's gone now, whatever

it was." Iron monsters! In a flash it had come to him that this girl

he held in his arms was Lina Shelton, daughter of the robot wizard. No

wonder she was afflicted with hallucinations! But those bruises were

real, as was the forcible twisting of her lithe young body. And he

_had_ heard something.

* * * * *

"You know me?" The girl was calmer now and faced him with a surprised

look.

"Yes, Miss Shelton. At least I recognize you from the pictures.

Society page, you know. And I'm Edward Vail--Eddie for short--on

vacation and at your service."

The girl smiled wanly. "You know of father's break with Universal

Electric? Of his private experiments?"

"I heard of the scrap and of how he walked out on the outfit, but

nothing further." Eddie thought grimly of how nearly he had come to

losing his own job when David Shelton broke relations with his

employers. He had been too enthusiastic in support of some of the

older man's claims.

"It's been terrible," the girl whispered. She clung nervously to his

arm as he picked the way back to the road. "The loneliness, and all.

No servants will stay out here now, and father spends all of his time

in the laboratory. Then--this fear of the mechanical men--they haunt

me. I--I guess they've got me a little goofy."

Eddie laughed reassuringly. "Perhaps," he suggested, "you will let me

help you. Your father, I believe, will remember me, and I'll be very

glad to--"

"No, no!" The girl seemed frightened at the thought. "I'm sure he

wouldn't welcome you. He's changed greatly of late and is suspicious

of everyone, even keeping things from me. But it's awfully nice of you

to offer your assistance, and you've been a perfect peach to take care

of me this way. I--I'd better go now."

They had reached the road and Eddie looked uncertainly at his

roadster. He hated to think of leaving the girl in this lonely spot.

She was obviously in a state of extreme nervous tension and, to him,

seemed pathetically helpless, and afraid.

"That the house?" he asked, pointing in the direction of the gloomy

old mansion whose dilapidated gables were barely visible over the tree

tops.

"Yes." The girl shivered and drew closer to him.

The ensuing silence was broken by the slam of a door. His car! Eddie

looked toward it in amazement; he was hearing things again. The

springs sagged on the driver's side as under the weight of a very

heavy occupant, but the seat was empty. Then came the whine of the

starter and the motor purred into life. The gears clashed sickeningly

and the car was jerked into the road with a violence that should have

stripped the differential. He pulled the girl aside just as it roared

past and disappeared around the bend in a cloud of dust. The sound of

the exhaust died away rapidly and left them staring into each other's

eyes in awed silence.

* * * * *

David Shelton was prowling around in the shrubbery when they

approached the house--a furtive, unkempt creature whom Eddie would

hardly have recognized. He straightened up and peered at his

daughter's companion with obvious disapproval.

"Lina," he said severely, "I've told you we want no visitors."

"Yes, Dad, I know, but Mr. Vail's car was stolen out in front and

there is no way for him to go on. We must look after him."

"His car--stolen? Who stole it?" David Shelton drew close and glared

suspiciously at his unwelcome visitor.

"One of your monsters, I think," she replied shakily, "though we could

see nothing. And the same thing attacked me and beat me. Look at my

bruises!"

Shelton was examining the marks, and his fingers trembled as he

touched his daughter's shoulder. He looked piteously into her eyes.

"Are you sure, Lina? Sure? Did you see it?"

"No, no. But I felt and heard--the iron arms and the clamps and the

buzzing. Oh, it was horrible!" The girl's voice rose hysterically.

"Oh, Lord! What have I done?" groaned Shelton. "It's true, then. Lina,

listen: I've succeeded in making them invisible, and one got away this

morning. But I thought--I thought--" He looked at Eddie, remembering

his presence suddenly. "But I'm talking too much. It seems to me I

remember having seen you before, young man."

"You have, sir," Eddie stated. "In the research laboratory of

Universal Electric. I work with Borden."

"They've sent you to find me?" Shelton stiffened perceptibly.

"Indeed, not, sir. I'm on vacation and was merely passing by when I

saw your daughter in danger, a danger I still do not understand."

"Yes, and he helped me to the road," Lina interposed, "and then lost

his car at the hands of--"

"Silence!" the father thundered. But his eyes fell before the fire

that instantly flashed in those of the girl.

"Now, you listen to me!" she returned angrily, "I've stayed on here

with you until I'm nearly crazy with your everlasting puttering and

experimenting--hearing your uncanny machines walking around in the

middle of the night--seeing impossible sights--then, this thing I

couldn't see but could feel. And you've gotten into such a state that

you'll go crazy yourself, if you continue. Something's got to be done,

I tell you. I can't stand it!"

* * * * *

Her voice broke on a choked sob.

"But Lina--"

"Don't but me, Father. I mean it. Mr. Vail discovered your hideout

quite by accident and he's been very nice to me. I tell you he means

no harm and I want him to stay. If you're not decent to him, if you

send him away, I swear I'll go too. I will--I will!"

Shelton's eyes misted and something of the hardness left his

expression. A look of haunting fear took its place and he stared

pleadingly at Eddie.

"Br-r! I'm cold!" Lina exclaimed irrelevantly. "And--and I believe I'm

going to cry." She turned away and raced for the shelter of the gloomy

old house without another word.

Eddie turned inquiring eyes on his unwilling host.

"Just like her mother before her," Shelton muttered softly. Then he

faced the younger man squarely and his shoulders straightened. "Mr.

Vail," he said sheepishly, "I've been a fool and I ask your pardon.

But Lina doesn't know. There's something tremendous behind all this,

something that's gotten beyond me. I'll send her away for her own

safety, but I must stay on. If--if only there was someone I could

trust--"

"You can trust me, sir," Eddie stated simply.

The older man paced the ground nervously, and Eddie could see that he

was under a most severe mental strain. Several times he halted in his

tracks and peered anxiously at his guest. Then he seemed to make a

sudden decision.

"Vail," he said sharply, "I need help badly. I want you to stay, if

you will. You swear you'll not reveal what I am about to show you?"

"I swear it, sir."

"You'll not report to Universal?"

"Never."

* * * * *

They surveyed each other appraisingly. Eddie was mystified by the

happenings of the day and was curious to learn more concerning these

mythical invisible creations. It was inconceivable that the scientist

had spoken truly of his accomplishment. Yet, he had done some

marvelous things with Universal and, maybe--well, anyway, there was

the girl.

"Come with me," Shelton was saying: "I believe you're a square

shooter, Vail." He was leading the way along the gravel path at the

side of the house. Before them loomed the squat brick building that

was the laboratory.

The door crashed open before Shelton's hand had reached the knob, and

one of those buzzing, unseen, monstrosities rushed clanking by,

knocking the scientist from his feet in its passage. Ponderous,

speeding footsteps crunched the gravel of the path, and then, with a

wild thrashing of the underbrush alongside, the thing was gone.

Eddie bent over the prostrate man and saw that he was unconscious. A

thin trickle of blood ran from a cut in the side of his head.

"Lina! Lina!" called Eddie frantically. For the first time in his life

he was genuinely frightened.

* * * * *

He half carried, half dragged the limp body through the door of the

laboratory and propped it in a chair. It required but a moment for him

to see that Shelton's injury was inconsequential. He had only been

stunned and already showed signs of recovering.

"What is it, Mr. Vail? What's happened?" came the voice of Lina

Shelton breathlessly. She was framed in the doorway, dressed now and

panting from her exertions in responding to his call. "Oh, it's

father," she wailed, dropping to her knees at his side. "He's been

hurt. Badly, too."

"No, not badly, Miss Shelton. He'll be around in a minute. I'm sorry

to have excited you, but when I called I feared it was worse than it

is." He was washing the blood from her father's small wound as he

spoke.

She took the basin from his hand, spilling some of the water in her

eagerness. "Here, let me have that cloth," she demanded.

Eddie admired her as her deft fingers took up the task. She was as

exquisite in a simple sport outfit as she had been in her bathing

suit.

The scientist opened his eyes after a moment. Remembrance came at once

and he sat erect in the chair, staring.

"Lina!" he exclaimed, grasping her hand conclusively. "You're here,

thank God! I dreamed--oh, it was horrible--I dreamed they had you." He

clung to her closely.

"They?" she murmured inquiringly.

"Yes. Two of them are loose now. It's danger for you, my dear. You

must leave at once. No, no--I can't let you out of my sight until they

are captured or destroyed." He rose to his feet in his agitation and

shook his head to clear it. He looked pleadingly at Eddie as if

expecting him to offer a solution of the difficulty.

"Vail!" he exploded, then, pointing a shaking forefinger at an

elaborate short-wave radio transmitter which occupied a corner of the

large room. "I ask you to bear witness. That is the source of energy

for these creations of mine and it's shut down. How on earth can they

keep going? I ask you."

"Perhaps someone else, sir," Eddie suggested doubtfully. "Have you any

enemies who might be able to duplicate the impulses of that

apparatus?"

"Bah! Enemies, yes--with Universal--but none who could duplicate the

complicated frequencies I use. My secrets are my own. I've never even

put them on paper."

* * * * *

Eddie was examining the intricate apparatus. "You knew of the first

one's escape, didn't you?" he asked. "How did it happen?"

Shelton again became the enthusiastic scientist. "Here," he said,

"I'll show you and you can judge for yourself." He strode to the

gleaming figure of a seven-foot robot of startlingly human-like

appearance.

Lina let forth an exclamation of repugnance and fear.

"No, Mr. Shelton," Eddie objected. "The same thing will occur again.

Then there will be three."

"We'll fix that, my boy." The scientist was removing cover plates from

the hip joints of the mechanical man. "I'll disconnect the cables that

feed the locomotors. He _can't_ walk then."

Eddie was still doubtful but dared offer no further objection,

especially since Lina Shelton was watching in wide-eyed silence. He

examined the monster and saw that it was quite similar in outside

appearance to those supplied by Universal for heavy manual labor,

excepting that this one was armed as were those used for prison

guards. There were the same articulated limbs and the various clamps

and hooks for lifting and heavy hauling; the tentacles for grasping;

machine guns front and back. Under the helical headpiece that was the

antenna this robot seemed to have two eyes--a new feature--but closer

examination showed these to be the twin lenses of a stereoscopic

motion picture camera. This robot, then, could see. Or at least it

could record what the lenses saw for its masters.

"There," Shelton grunted when he had finished his tinkering, "he's

paralyzed from the waist down. Let this one try and get away from us."

"Guns aren't loaded, are they?" Eddie asked.

"Lord, no! Never have any of them loaded. That _would_ be a fool

stunt." Shelton had pulled the starting handle of a motor-generator

and its rising whine accompanied his words.

* * * * *

The vacuum tubes of the transmitter glowed into life and the scientist

manipulated the controls rapidly. Lina was watching the robot with

fascinated awe. Its arms moved in obedience to the controls, tentacles

waved and coiled; the humming of its internal mechanisms filled the

room. The locomotion controls had no effect, as the scientist had

predicted. Eddie drew a sigh of relief.

"Now, Vail, watch," Shelton exulted. "I'll show you what I was doing

with the first one." He closed a switch that lighted another bank of

vacuum tubes behind the control panel.

"You can make this one invisible?" Eddie asked incredulously.

"Certainly--from the waist up. This ought to be good."

"Mind telling me the principle?"

"Not at all--now. I've your promise of secrecy. It's a simple matter,

Vail, really. Just a problem of wave motions--light. Invisible light;

the ultra-violet, you know. My robots are built of specially alloyed

metals which permit great freedom of molecular vibration. The

insulating materials and even the glass of the camera lenses are

possessed of the same property. Get it? I merely set up a wave motion

in the atoms of the material that is in synchronism with the frequency

of ultra-violet light, which is invisible to the human eye. All

visible colors are absorbed, or more accurately, none are reflected

excepting the ultra-violet. Perfect transparency is obtained since

there is neither refraction nor diffraction of the visible colors. And

there you are!"

Eddie stared at the upper half of the robot and saw that it was

changing color as Shelton tuned the transmitted wave. Then suddenly it

was gone. The entire upper portion of the mechanism had vanished; had

just snuffed out like the flame of a candle. He could see down into

the tops of the thing's hollow legs. Shelton laughed at him as he

stretched forth his hand and hesitatingly felt for the invisible

mid-section and upper body. It was there all right, unyielding and

cold, that metal body. But no trace of it was visible to the eye. He

drew back his fingers as if they had touched a hot stove. The thing

was positively uncanny.

"Dad! Turn it off--please," Lina begged. "It's getting on my nerves.

Please!"

Obligingly, Shelton pulled the switch. "Now you'll see," he said to

Eddie, "whether the same thing happens. Watch."

* * * * *

Mistily at first, the outlines of the monster's torso and arms came

into view, semi-transparent but clouding rapidly to opacity. Then it

glinted with the barely visible violet, a solid once more, rigid and

motionless. It was a lifeless mechanism, for the source of its energy

had been cut off. Eddie had an almost irresistible impulse to pinch

himself.

Then he gasped audibly, as did Shelton, for the thing snuffed out of

sight again without warning, and the hum of its many motors resumed.

There came a terrific clanking as it waved arms and tentacles and

violently threshed with its upper body. But the visible portion, its

legs, remained rooted to the floor of the laboratory. Lucky it was

that the scientist had disconnected those wires; lucky too that the

machine guns were empty of ammunition.

"There now--see?" Shelton's voice rose excitedly. "It's been no fault

of mine. The power is off but it moves--it moves. What on earth do you

suppose--"

Eddie's shout interrupted him. He had seen something at the window: a

face pressed against the pane and contorted with unutterable malice.

Then it was gone. With the shout of warning still in his throat, Eddie

bounded through the door in pursuit of the intruder. Lina's cry of

recognition followed him into the twilight. "Carlos!" she had called.

He saw a stocky figure slink around the corner of the laboratory and

make for the underbrush beyond. In a flash he was after him. No, he

thought grimly, Shelton hadn't any enemy clever enough to duplicate

his transmitter! The hell he didn't! Who the devil was this fellow

Carlos anyway? He tore savagely at the impeding branches as he plunged

deeper and deeper into the thicket.

* * * * *

It was a fruitless chase and Eddie soon retraced his steps to the

laboratory. Swell mess he'd gotten himself into! His car was gone:

probably wrapped around a tree by this time. And here was a situation

that spelled real danger, a thing with which Shelton was utterly

unable to cope. As a matter of fact, he was so impractical--such a

visionary cuss, after the fashion of all geniuses--that he'd never be

convinced of the seriousness of the matter until it was too late. What

to do? The girl was a corker, though, and game as they made 'em. Just

the sort a fellow could tie to....

Lina's firm clear voice came to him through the open door of the

laboratory. "Dad," she was saying, "why don't you give it up? Let's go

back to New York where it is safe for you and for me. Let the things

go and forget about them. What do they amount to, after all? We've

plenty of money and you already have earned enough fame to last the

rest of your life. Come on now--please--for me."

"What do they amount to?" Shelton reiterated, his voice rising

querulously. "Lina, it's the most tremendous thing I've ever done.

Think for a moment of what my robots could accomplish in the next war.

And there'll be a next war as sure as you're alive. Think of it! No

sending of our young manhood into the bloody fields of battle; no

manning of our air fleets with the cream of our youth; no bloodshed on

our side whatsoever. Instead, these robots will fight the war. They'll

fight other robots too, no doubt, but the property of invisibility

will be an invincible weapon. It will be a war that will end war once

and for all. You can't--"

"Nonsense, Father," the girl returned sharply. "You've let your

enthusiasm run away with your judgment. See what's happened

already?--someone's figured it out before you've even perfected the

thing. An enemy of our country could do the same in wartime. Maybe

it's a foreign spy who has done what's been done to-day."

* * * * *

Eddie walked into the laboratory. "Couldn't find him," he announced

briefly.

"No difference," said Shelton. "He doesn't count in this. We called to

you when you rushed out, but couldn't make you hear."

"Who is he?" Eddie asked shortly. What he had overheard made him more

than ever impatient with the older man. So clever and yet so dense,

Shelton was.

Lina avoided his gaze.

"Only Carlos--Carlos Savarino," said Shelton, carelessly, "a Chilean,

I think. He worked for me for two months during the summer and I fired

him for getting fresh with Lina. Good mechanic, but dumb as an ox. Had

to tell him every little detail when he was doing something in the

shop. I'd have saved time if I'd done it myself."

The girl looked at Eddie squarely now. She was flushing hotly. "And I

horsewhipped him," she added.

"Yes," Shelton laughed; "it was rich. He sneaked away like a whipped

puppy, and this is the first time we've seen him since."

Eddie whistled. "And you think he doesn't count in this?" he asked.

"Of course not. Too dumb, I tell you. Doesn't know the first

principles of science. He thinks the only wave motion is that of the

ocean." Shelton chuckled over his own jest.

"I wouldn't be too sure," Eddie snapped. "And I want to tell you

something, Mr. Shelton. Through no fault of my own, I heard some of

your conversation with Li--with your daughter, before I returned here.

I was puzzled over your reasons for working so absorbedly on this

thing, but now I know them and I think you're wasting your time and

keeping your daughter in needless danger."

"You dare talk to me like this!" Shelton roared.

"I do, sir, and you'll thank me later." Eddie returned the older man's

glare with one equally savage.

Lina's gurgle of laughter broke the tension. "He's right, Dad, and you

know it," she interposed. "Let him finish."

Eddie needed no such encouragement, though it warmed his heart. And

Shelton listened respectfully when he continued, "I'm into this now,

sir, and I intend to see it through to the end. I'll keep your secret,

too, though I doubt if it'll ever be of much value to you. Know what I

think? I think this Carlos is a damn clever fellow instead of the ass

you took him to be. He probably just pretended he was ignorant of

science. Why shouldn't he? That way he got a liberal education from

you in the very things he wanted to find out. Since you tied the can

to him he's had plenty of chances to build a duplicate of your control

apparatus--with the aid of some foreign government, no doubt--and now

they've stolen two of your machines to complete the job. Your secret

already is out and in the very hands you've tried to keep it from."

* * * * *

Shelton paled visibly as Eddie talked. "But--but how--" he stammered.

"How should I know how they did it?" the younger man countered.

"Here--let's take a look around. I'll bet they've left their trail

right here in this room."

He walked from one end of the laboratory to the other, peering into

corners and under work benches as he passed. Shelton trailed him like

a shadow, squinting through the square lenses of his spectacles.

They carefully avoided the partially invisible robot, for the humming

of its upper motors continued and clanking sounds occasionally issued

from the unseen upper portion. The enemies of David Shelton were still

at work on their hidden controls.

"Here--what's this?" Eddie exclaimed suddenly, pointing out a glinting

object in a dark corner of the laboratory.

Shelton examined it closely, looking over his shoulder. The object he

had located seemed to be a mounted and hooded lens, a highly polished

glass of about two inches diameter with its mounting attached rigidly

to the wall.

"Never saw that before," Shelton stated with conviction. "And--why--it

looks like an objective such as those used in the latest automatic

television transmitters."

"Just what it is," Eddie grunted. He picked up a pinch bar from a

nearby tool rack and drove its end through the glass as he spoke the

words.

A violent wrench tore the thing loose and broke away a section of the

thin plastered wall. There, in the cleverly concealed cavity behind,

was revealed the mechanism of the radio "eye." Somewhere, someone bad

been watching their every move. And abruptly the thrashings of the

robot ceased and its upper portion again became visible.

* * * * *

"Well," said David Shelton. "Well! Looks as if you're right, young

man. I'm astonished." His watery eyes looked sheepishly over the rims

of his glasses.

Lina watched their every move. She seemed to sense the seriousness of

the situation far more than did her father.

Then the lights went out. It had darkened to night outside and the

blackness and silence in the laboratory was like that of a tomb.

"They've cut the wires," Eddie whispered hoarsely. "Got any weapons

here, Shelton?"

"Yes. A couple of automatics. I'll get them." The scientist was no

coward, anyway. His whispered words came calmly through the silence.

Eddie heard him shuffle a few steps and fumble with a drawer of the

desk. In a moment the cold hard butt of a pistol was thrust into his

hand. It had a comforting feel.

"Stay here with Lina," he commanded. "I'll go out and see if I can

find them. This looks nasty to me."

"No," came the girl's voice, "I'm going too."

"You are not," Eddie hissed. "You'll stay here or I'll know the

reason. It's dark as a pocket outside and my eyes are as good as

theirs. I'll get 'em if they're around here. You hear me?"

"Yes," she whispered meekly.

Edward Vail, only that morning headed for rest and quiet, was now out

in the night, stalking an unknown and vicious enemy. And--for what? As

he asked himself the question, the smile of Lina seemed to answer him

from the blackness. Cherchez la femme! He was getting dotty as he

neared his thirties. Maybe it was the hard work that had affected his

mind.

* * * * *

The black hulk of the old house loomed against the scarcely less dark

sky. There was no moon, and in only one tiny portion of the heavens

were the stars visible. Mighty few of them at that. The swish-swish of

the surf came to his ears faintly. Or was it someone creeping along

the wall of the house? He held his breath and waited.

They wouldn't use the robots at night. Couldn't follow their movements

in the teleview, if such an attachment had been built into their

control transmitter. No, the devils would be here in person.

A muttered Teutonic curse sounded close at hand. That wouldn't be

Carlos. God! Were the heinies mixed up in this thing? Just like 'em to

be swiping a new war machine; but hadn't they gotten enough in 1944?

Without warning he was catapulted from his feet by the impact of a

heavy body. He struck the ground so violently that the pistol was

jarred from his hand. Disarmed before the fight had started!

Then he was rolling over and over, battling desperately with an

assailant who was much larger and heavier than himself. He was dazed

and weakened from his initial dive to the hard ground. All rules of

boxing and wrestling were forgotten. Biting, kicking, gouging, all

were the same to this silent and powerful antagonist. It was

catch-as-catch-can in the darkness, and mostly the other fellow could

and did. He had a grip like the clamp of a robot. Trying to dig out

one of his eyes? Eddie saw stars--and lashed out with all his might,

his flying fists playing a tattoo on the others ribs. Short arm jabs

that brought grunts of agony from his big assailant. Try to blind him,

would he?

Eddie somehow managed to get on top; his clutching fingers found the

other's collar. Then he let loose with terrific rights and lefts that

smacked home to head and face. Those outlanders don't like the good

old American fist, and Eddie had room to bring them in from way back,

now. The fellow had ceased struggling and Eddie's hands were getting

slippery. Blood! Must be, for the stuff was warm and sticky. He rested

for a moment, breathing heavily. The other was quiet beneath

him--knocked cold. He staggered to his feet triumphantly; wondered how

many more of them there were.

* * * * *

He looked around in the darkness, straining his eyes in vain to pierce

its thick veil. There was a glimmer of light over there, through a

window. The laboratory! The light flickered a second and vanished. A

cold fear gripped him and he stumbled through the grounds blindly,

finally colliding painfully with the brick wall. He felt his way

toward the door, or where he thought it should be.

He dared not call out for fear the others would hear. Where was that

damned door? He rested again and listened. Not a sound was to be

heard from within or without. He clawed his way frantically along the

unsympathetic wall. It was a mile wide, that laboratory of Shelton's.

Ah--at last! Weakly, he staggered within.

"Lina!" he whispered, "Lina! Shelton!"

There was no reply. He fumbled for a match. Funny how slowly his mind

worked ... thoughts coming jerkily like a sound film running at quarter

speed ... fingers shaking so he could scarcely strike a light. The flare

showed the laboratory empty of human beings ... Lina gone ... that crazy

robot ... quiet now, and visible ... but grinning at him ... then

darkness....

* * * * *

What a headache! Eddie rolled over and groaned. Astounded by the

hardness of his bed and the stiffness of his joints, he roused to

instant wakefulness; sat up and stared. Where the devil was he? The

laboratory--Shelton's--Lina. He jumped to his feet. Dawn was breaking

and its first faint radiance lighted the robot with eery shifting

colors. He berated himself: he'd passed out.

He dashed through the door and made a wild circuit of the grounds.

Empty! No--there was his automatic, where it had fallen. Blood stains

on the grass showed where the encounter had taken place last night.

Must have smashed the Dutchman's nose. But he was gone. Everybody was

gone. He rushed into the house and from room to room, upstairs and

down. The place was deserted.

This was something to think about. Not an automobile around, no

neighbors, not even a telephone. When Shelton went into seclusion, he

did it thoroughly. Eddie returned to the laboratory and hunched

himself in the scientist's chair. Maybe he could think better here.

They had Shelton and his daughter, all right. Kidnapped them. There

was probably some detail of his discovery they couldn't dope out, and

had decided to force him into telling them. The devils would use

Lina's safety as a threat to force him into anything. Horrible, that

thought. And Carlos already had made advances to her.

Startled by a sharp click, he turned around. The robot was whirring

into life. Fast workers, whoever Shelton's enemies were, and up early!

He found the pinch bar with which he had wrecked the television

apparatus and, with a few mighty blows, destroyed the antenna and

headpiece of the mechanical man. They'd not pull off any devilment

with this one, anyway.

A wave meter on one of the benches attracted his attention and he

twirled its knob. It gave strong indication at one and a half meters.

The wave length of their control transmitter! If only he could

find--but there it was: a direction finder. Hastily, he lighted its

tubes and tuned to the frequency shown by the meter. He rotated the

loop over the compass dial and carefully noted maximum and minimum

signals. He had a line on the transmitter! And it must be close by,

for the intensity of the carrier wave was tremendous.

* * * * *

Slipping the automatic into his pocket, he left the laboratory and

struck out through the underbrush in the direction Carlos had taken

the day before. Fighting his way through the tangled shrubbery, he

kept his eyes constantly on the needle of the magnetic compass he had

wrenched from the direction finder. It was tough going through the

thicket, and just as bad across a swampy clearing where he was mired

to the knees before he got across. Up the hill and into the woods he

forged, keeping doggedly to the direction he had determined. This was

rough country, less than a hundred miles from New York but

uncultivated and unsettled excepting for the few summer places along

the shore. He'd heard that these backwoods were infested with

rum-runners and hijackers, a cutthroat gang.

There was a cabin off there through the trees, almost on the line he

was following. Must be what he was looking for. He advanced

cautiously, creeping stealthily from tree to tree.

Voices came to his ears, and the throb of a motor-generator. It was

the place, all right. He crept closer, and, circling the house, saw

that an almost impassable road led to it from the rear. A heavy

limousine was parked there in the trees, and another car, a yellow

roadster--his own. A feeling of grim satisfaction was quickly

dispelled by the sound of a familiar humming. Within a foot of his

ear, it seemed to be, and instinctively he ducked.

Click! A powerful clamp had fastened itself to his wrist. One of

Shelton's invisible robots! He struck blindly at the unseen monster

and was rewarded by a shooting pain up his wrist as one of his

knuckles was driven backward by the impact with the hard metal. Bands

of writhing metal encompassed his body, pinning his arms to his side

and lifting him bodily from the ground. There he hung, kicking and

struggling in mid-air, supported by nothing he could see. He closed

his eyes and felt of the thing that held him. Cold, hard metal it

was--implacable and unyielding.

Clank, clank. The monster was walking with long, jerky strides. The

pressure against his ribs brought a gasp of agony from his lips. Each

jarring step was an individual and excruciating torture. His breath

was cut off by the relentless constriction of one of the tentacles

which now encircled his neck. It wouldn't be long now.

* * * * *

Then, when everything had turned black and he had given up hope, he

was dumped unceremoniously on the hard floor of the cabin. A harsh

laugh greeted him as he struggled weakly to his knees.

"Thought you could put one over on Al Cadorna, did you?" a voice

rasped.

The room spun round as he tried to regain his feet. A mist swam

before his eyes. Al Cadorna! The most picturesque figure in gangland.

Credited with a dozen killings and with ill-gotten wealth untold, this

leader of the underworld openly boasted that the police had never

gotten anything on him. And they hadn't. So it was a criminal who had

laid hands on Shelton's robots, not a foreign spy. Worse and worse. He

thought of what they might be able to do with these invisible

mechanical things: make gunmen out of them; safe blowers; house

breakers. Why, society would be at their mercy; banks defenceless; the

mints, even--

"Stand up on your pins, you worm! Let's have a look at you!" The

muzzle of an automatic was thrust in his abdomen, prodding

insistently. Things stabilized in the room and he looked up into the

cruelest face he had ever seen, and recognizable from the many

pictures which had appeared in the yellow press.

Eddie took in the surroundings at a glance. He was in a low-ceilinged

room that was almost unfurnished. In one corner there was a replica of

Shelton's robot control, teleview disc and all. Carlos had just pulled

the switch and the robot was taking visible form. The man who prodded

him with the automatic was Cadorna, no doubt of that. His evil leer

and yellow eyes marked him at once. The other occupant of the room was

a big square-built man with a patch over one eye and strips of

adhesive tape across his nose--his antagonist of the night before.

Must have sneaked off after he came to; it was safer to send one of

the robots after the _verdammt Amerikaner_. Eddie restrained a chuckle

at the thought.

"Nothing to laugh at, kid!" Cadorna snarled. "You're goin' for a nice

long ride pretty quick. Know that?"

Eddie's head was clearing rapidly, but he pretended to sway on his

feet. Lina and her father were not in sight. If only he could spar for

a little time.

"What's the idea?" he asked. "Haven't you guys got enough?"

"That's our business. We know what we're doin', and when you butted in

you just signed your own papers. Dead men don't talk, you know, kid!"

* * * * *

There was a door at the other side of the room. If only he could see

whether Lina was in there; whether she was alive.

"Tie him up, Gus!" Cadorna kept the pistol pressed into the pit of

Eddie's stomach as he gave the order. "Hands and feet--and make it a

good job, you wiener."

Eddie shouted then. "Lina!" Resistance was useless, but it would give

him some satisfaction to know she still lived even though Cadorna

pulled that trigger in the next instant. No reply came from beyond

that door.

"So!" Cadorna grinned maliciously. "Another victim! Carlos first, then

you, and now--Al Cadorna. If you're worrying about her, kid, you

needn't. She'll be perfectly safe with me."

Eddie's roar of rage shook the rafters. Heedless of consequences, he

brought his knee up suddenly and violently. Cadorna sank to the floor

with a groan, his pistol clattering harmlessly on the rough planks. In

a flash Eddie retrieved it, dropping behind the prostrate form of the

stricken gangster. Gus had fired and missed. Now he dared not shoot

for fear of hitting his chief. Eddie's gun spat fire and the big

German clapped his hands over his heart, his good eye widening in

surprise. Then he reeled and pitched forward on his face. A feminine

cry sounded from the adjoining room and Eddie's heart skipped a beat

when he heard it.

Carlos was padding across the floor, trying to get into a position

where he could fire without endangering Cadorna. Eddie swung his

pistol around and pulled the trigger. A miss! He fired again, but too

late. Fingers of steel had gripped his wrist and the king of gangland

rolled over on him, twisting the gun from his hand. Clubbed now, the

pistol was raised high over that distorted, malicious face. Eddie

tried to twist away from under the blow as it started its downward

swing, then a thousand steam hammers hit him all at once and ...

blackness....

* * * * *

Something was pounding insistently at the doors of his consciousness.

He must pull himself together! They'd left him for dead and he

was--almost. But voices as loud and raucous as those would waken the

dead. He groaned with pain when he attempted to move his head.

"That for you, you rat." It was Cadorna's voice. "Try to take my

woman, will you?"

The pounding resolved itself into the angry barking of an automatic.

Someone squealed with mortal agony. Eddie opened his eyes cautiously

and saw that the room was full of people. The pungent odor of burned

powder assailed his nostrils. There was Cadorna and Carlos, David

Shelton and Lina. An undersized, dapper youth stood over the body of

the big German, his hands outstretched before his horror-stricken

face. A moment he stood thus, like a statue. Then his knees gave way

beneath him and he crumpled into a grotesque heap beside the man who

had been called Gus. Such was the manner of Cadorna's dealing with

those who displeased him.

The door to the adjoining room was open. Lina and her father had been

kept in there, with the little thug as their guard. Evidently Cadorna

had caught him trying to force his attentions on the girl. Good thing

he'd killed him.

Lina was sobbing and the sound brought increased agony to the helpless

Eddie. He lay still where they had placed him, beside the table which

supported the robot control apparatus. His cheek was against the floor

and he saw that a little pool of blood was forming there, blood drawn

by the butt of Cadorna's pistol when it contacted with his skull. He

was bound hand and foot. They hadn't thought him dead, after all.

Keeping him for that ride and a watery grave. Couldn't afford to leave

his body around where it might be found.

"What are you going to do with us?" Shelton was asking, his voice

bravely defiant. Game old sport at that, he was.

"Don't fret over your daughter. Al Cadorna's her protector now, and

she'll be taken care of better'n she's ever been. But you--that's

somethin' else again. First off, you're goin' to give Carlos the dope

on these trick metals in your machines. He couldn't analyze 'em, or

whatever you call it. Then you're goin' to have a nice long ride with

your friend over there."

"You'll go to the chair for this, Cadorna. And I'll never tell you the

secret of the alloys."

"Tell him, Dad," Lina was crying. "He'll let us go if you do."

"The hell I will, girlie. What I said, goes. We'll make him talk

first, too," Cadorna snarled.

"Never!" Shelton shouted.

* * * * *

Lina had seen Eddie and, with a little cry, she bounded across the

room. Carlos was after her like a panther.

"Hands off that dame!" Cadorna yelled. "Let her cry over the boy

friend if she wants to. Won't do her any good. You get busy and set

one of the tin soldiers goin'. Make the old buzzard talk."

Carlos muttered sullenly as he started the motor-generator. Give him a

chance and he'd knife Cadorna in the back--for Lina.

The girl was kneeling at Eddie's side now, examining his bleeding

scalp. He opened one eye and gazed at her solemnly, pursing his lips

in a warning to silence. She caught her breath and nodded in

understanding.

Cadorna was shouting like a madman. "Keep the damn thing so I can see

it, you spig! They make me bug-house when you blink 'em off. Besides,

I don't trust you."

The bold Cadorna was afraid of something he couldn't see! An idea

flashed across Eddie's quickening mind. But he was helpless--bound so

tightly that the cords cut his wrists.

One of the robots was clanking across the room. Lina looked up in

momentary terror and Eddie saw her eyes stray over the table top where

Carlos was working.

"Want to grab the old one?" the Chilean called.

"Yes. Pick him up and squeeze him till his ribs crack. He'll talk."

Lina let a little moan escape her lips. Eddie was watching as the iron

monster approached the scientist and flung its tentacles around his

madly struggling form. Lina was fussing with him, trying to turn him

over. Cadorna's back was to them, his face thrust into that of

Shelton, who was fighting desperately to avoid the crushing grip of

the robot.

"Give him a squeeze, Carlos."

* * * * *

Shelton's yell brought another low moan from the girl's set lips. She

was working furiously at Eddie's bonds. Lord, she had a knife! Good

girl! Must have found it on the table. His hands were free and he

wriggled his fingers to bring them to life. Then his feet. He was able

to move. Lina whispered in his ear.

"All right?" she asked anxiously.

"Yes," he whispered. Somehow their lips touched and Eddie felt his

heart pound at his temples. New life came to him with a rush of

exaltation.

Shelton was crying out in pain and Lina sprang to her feet. "You

beast!" she shouted at Cadorna. "Let him go."

Then she was across the room, tearing at the unyielding metal bands

that pinioned her father and slowly crushed him. Cadorna laughed

mirthlessly.

"Tell him to give me the dope," he retorted. "Then I'll let him

go--for a while."

Shelton's head hung on his chest, rolling weakly from side to side.

Eddie doubted whether he could speak if he wished to. The Chilean was

working at the controls, increasing the tension of those terrible

tentacles. Eddie raised himself to his knees, watching Cadorna

narrowly. He fingered the knife Lina had used in freeing him. No, he

couldn't use that. The Chilean would cry out and queer everything. He

laid it on the floor, within easy reach.

Cadorna was cursing now, first Shelton and then the girl. His rage was

maniacal. "Another notch!" he bellowed.

Eddie rose silently and clamped his fingers on the Chilean's windpipe.

Lina's eyes widened as she saw. She did everything in her power to

keep Cadorna's attention occupied as Eddie sunk those fingers into

Carlos' throat. The Chilean's eyes popped from his head as he

struggled furiously to tear away the steel-sinewed hand that had

stopped off his breath. Death was staring him in the face, and he

could not cry out. His strength left suddenly as the fingers dug in

deeper, and Eddie shook him as he would a rat. In a surprisingly short

time he had slumped to the floor, and not until his squirmings ceased

did Eddie loose that awful grip.

"Another notch, you spiggoty!"

* * * * *

Eddie bent over the controls. Lina's pleadings mingled with the curses

of Cadorna. She was cajoling now--telling the brute she'd go with him

gladly if only he'd free her father; promising anything, everything,

in the desperate attempt to keep him from discovering that his last

henchman was out of the picture. But her words served only to spur

Eddie to swifter action. He twirled the knobs of the dual control. The

second robot was fading from view. He'd give Cadorna a dose of the

thing he really feared. He eased off a little on the other control,

releasing the pressure on poor Shelton's ribs as much as he dared.

The position indicator of the second robot moved slightly as Eddie

started the invisible monster toward the yelling gangster. He watched

the screen closely. It was quite a trick, at that, controlling these

things you couldn't see. All you had to go by were these sketchy

representations in the teleview; tiny flecks of light that outlined

the various movable members of the robot.

"Eddie!" Lina screamed suddenly. "Look out!"

But he had seen Cadorna wheel around as he watched his image on the

screen. At that moment a tentacle was writhing its way around his

thick neck. A bullet whistled past Eddie's ear and buried itself

harmlessly in the wall.

Then from the blasphemous mouth of the king of gangland there came a

shriek of awful fear. The tightening tentacle shut it off in a choking

gurgle. Cadorna was captured at last--by a monster he could not see, a

monster that struck terror to his craven soul.

It was the work of but a moment to free David Shelton from the grip of

the other robot. The tortured man tottered into Lina's arms for

support.

Eddie played with Cadorna now, releasing the grip from his throat and

pinioning his arms instead. With rapid fingers he manipulated the

controls until the screaming gangster was raised high in the air by

the unseen arms of the robot.

"Another notch, Al," he chortled.

Cadorna yelled anew as the clamps tightened, "For God's sake, kid,

quit it! Let me down. I'll do anything you say."

"Yeah?" Eddie moved one of the rheostat knobs a trifle.

The prince of racketeers was whimpering now, like a baby. The sharp

snap of a rib punctured his outcries.

"Another notch," said Eddie grimly.

But the king of the underworld had fainted.

* * * * *

An hour later Eddie Vail surveyed the scene complacently. Lina had

washed the blood from his head and face and bandaged his wound.

Luckily, Cardorna's blow had been a glancing one. The girl was fussing

over her father, now, and the scientist was on the point of resenting

her attentions; swore he could take care of himself; he wasn't a baby.

Carlos and his chief were trussed up like mummies, and had been

snarling at each other ever since the Chilean recovered his senses,

each blaming the other for their predicament. The robots stood

motionless by the wall.

This would be a big haul for the police. Plenty of evidence to send

Cadorna to the chair now. The murder of Butch Collins, the undersized

thug, had been witnessed by three of them. No, four: Carlos would

squeal. He was that kind. There would be rejoicing in the underworld

too, for Cadorna had many enemies. They'd be killing each other off in

droves though, for the leaders of rival gangs would be battling for

his place.

"Guess we'll have to dump them in the limousine," he remarked to

Shelton. "Drive them to the nearest town and turn them over to the

authorities."

"Yes. Then they can come back for the bodies of the other two."

Shelton grimaced as he contemplated the sprawled figures.

"What about your robots?" Eddie asked.

"Why, I'll go ahead with my original plans, of course." The scientist

looked surprised.

"Dad!" Lina turned beseeching eyes on Eddie and his heart performed

amazingly as he looked into their depths.

"And why not?" asked her father dolefully. "They'll insure the peace

of the world. They'll--"

"Listen, Mr. Shelton," Eddie interrupted. "If you'll think a little

you'll realize that they'll do no such thing. Has any new and terrible

engine of destruction ever accomplished that result? No--the enemy

always finds a way of combating the new weapon and of devising another

still more terrible. You've discovered a marvelous thing, but its

value is quite problematical."

"How can they ever combat a thing they cannot see?"

"Easily. Why, I could devise a teleview attachment in two days that

would make them visible. Photo-electric cells are capable of detecting

ultra-violet light as you well know. Radium glows under its rays. Why

not coat a teleview screen with some radio-active material?"

* * * * *

Shelton frowned thoughtfully. "You're right. Vail," he said, after a

moment of silence; "absolutely right. It was only a dream."

With dragging feet he walked to the transmitter, his expression grim

in the realization of failure. He started the motor-generator with a

gesture of finality.

"What are you going to do?" Eddie asked fearfully.

"Watch me! At least I can demonstrate another phase of the basic

principle I have discovered."

The motors of both robots whirred.

"Don't!" Cadorna wailed. "For God's sake, don't blink 'em out!"

Carlos cursed his chief for a coward.

Shelton was talking rapidly as he manipulated the controls. Instead of

building up the wave motion to the frequency of invisible light he was

reducing it. Past the other end of the spectrum and into the

infra-red. The heat ray! Both monsters were changing color as he

marched them through the door and into the open. But now they glowed

with a visible red that rapidly intensified to the dazzling whiteness

of intense heat. Cadorna babbled in superstitious terror. Then, in an

instant, both mechanisms were reduced to shapeless blobs of molten

metal. Lina clapped her hands gleefully.

Shelton looked up with enthusiasm once more shining in his face.

"Vail, my boy," he said, "we can find some use for that in industry.

Let the next war take care of itself."

"You bet!" Eddie was lost in contemplation of the girl--the flush of

pleasure that came at her father's words; the shining eyes.

"Then you'll leave the old place down here?" she asked eagerly.

"Yes, as soon as we get rid of these crooks and the other robot. Vail

is to spend the rest of his vacation with us, too--if he will."

Would he? Eddie gazed at the girl in rapt admiration and with an

inward thrill over his astounding good fortune. Her eyes dropped

before the intensity in his and her flush heightened.

David Shelton was wiping his glasses and peering at them with an

understanding smile. Good sport, Shelton--and in some ways as wise as

they made them. Eddie waited breathlessly for the girl to speak.

"Oh, that's wonderful, Dad," she approved; "and I'm sure that Mr. Vail

will agree."

She turned those glorious eyes on Eddie once more and her inquiring

smile spoke volumes. He opened his mouth to accept the invitation but

the words would not come. He could only nod his head vigorously like

an abashed schoolboy.

Some vacation!

Phalanxes of Atlans

_By F. V. W. Mason_

CONCLUSION

WHAT HAS GONE BEFORE

[Illustration: _Yes, there came a strange, but welcome sight._]

[Sidenote: Never did an aviator ride a more amazing sky-steed than

Alden on his desperate dash to the great Jarmuthian Ziggurat.]

Victor Nelson and Richard Alden are forced down on a flight over an

unexplored Arctic region. Returning from a hunt for food, Nelson finds

his companion gone; but many footprints and blood splashes establish a

clear trail to a tunnel, passing beneath a range of very high

mountains on the edge of the unexplored area. In following the trail,

Nelson encounters and slays an allosaurus, a terrible, carnivorous

species of dinosaur surviving from the Cretaceous era.

Then he presses on to presently emerge in an almost tropical valley

and encounter a remnant of the long lost Atlantean race, who are ruled

by a dynasty of English-speaking kings--descendants of Sir Henry

Hudson, who had wandered into Atlans after being abandoned by his men.

This valley in the Arctic owes its existence to the thinness of the

earth's crust, which permits the interior heat to warm the surface.

The Atlanteans are on the verge of war with another race, the

Jarmuthians, descended from the Lost Tribes of Israel, when Nelson is

transported to Heliopolis, the Atlantean Capital, for trial. All

strangers must prove their value to the State or be condemned to feed

the war monsters.

Nelson soon discovers that Alden had been captured from the Atlanteans

by the Jarmuthians. He strikes a bargain with Altorius, Emperor of

Atlans. He will undertake to fight any six of the enemy on condition

he and Alden will be released if successful.

Altorius agrees to Nelson's suggestion and makes a proposal to the

Jarmuthians. Heretofore he had been paying them an annual tribute of

six maidens, as price for the safety of Altara, Sacred Virgin of

Atlans, whom Jarmuth had captured in a previous war. With Nelson's

bargain in mind he offers an increase of six maidens to the annual

tribute, if the American fails to defeat six Jarmuthian champions. On

the other hand, if Nelson wins, all tribute will cease, Altara will

not be sacrificed, and Alden is to be returned unharmed.

On a dueling ground between the rival armies Nelson, armed with his

Winchester rifle, sallies out to battle with the enemy, who, on their

side, are armed with retortii--curious weapons hurling live

steam--fungus bombs, swords and lances.

The tricky Jarmuthians, however, mount their men on a diplodocus, a

huge dinosaur some eighty-seven feet in length. All seems lost; but by

blinding the colossal creature, Nelson destroys its usefulness, and

one by one kills the six Jarmuthians.

Stung with rage, the enemy disregard the terms of the contest and

attack with their whole army. They are, however, defeated, and the

conquered Jarmuthians sullenly turn over Alden and the captive

maidens; though Altara still remains in their possession.

After making much of the Americans, Altorius reluctantly allows his

preservers to depart for their plane--unconscious that the priestly

party is planning rebellion against his authority because he did not

insist on Altara's return.

CHAPTER VII

"That's one of the fixed retortiis I was speaking about," remarked

Victor Nelson as he paused to point out a tapering brass tube which

was mounted on a platform above the long staircase up which he and

Alden were toiling. "It's a big brute: see how small the gunners look

beside it? These steam guns are wonderful things."

The younger aviator sighed. "I've had enough of miracles," he said

wiping his flushed features and hitching a small pack higher on his

leather-clad shoulders. "All I want to do is to lay my weary eyes on

the plane again. What with these ghastly allosauri, diplodocuses and

other monsters, I'm damn well fed up with this place."

Nelson settled his Winchester rifle more comfortably into the hollow

of his arm. "Correct. So am I. But we can't say Altorius didn't do

right by our Nell. Good Lord, what a triumph he gave us!" The dark

pilot's smile flashed from beneath his neat, close-clipped black

mustache. "Wait till Cartier gets a peep at those diamonds he gave

us."

Panting, the two halted by mutual consent. "Ever see so many stairs?"

grunted Nelson. "Three more flights and we'll be into the tunnel; ah,

there's the opening. I only hope these blighters haven't hurt the

plane."

Before resuming the climb Nelson shifted his rifle, idly regarding the

armored gunners just above; then suddenly he stiffened his wiry body

with a sharp cry. "Look out, Dick! What the devil? Those damn fools

ahead are swinging the retortii across our--"

* * * * *

The dark haired aviator's words were drowned out in a deafening,

hissing roar that burst from the great retortii's throat, and his

heart gave a great convulsive leap at the sight. Was this an

accident--or treachery? An accident of course. Somehow he could not

bring himself to think that Altorius would break his pledged word.

Projected in a shimmering white arm the scalding death vapor shot

across the staircase, its hot breath licking the faces of the startled

and angry Americans, and quickly forcing them to turn and run

downwards to avoid being scalded.

"What the devil are these idiots trying to do?" gasped Nelson,

anxiously eyeing the red-crested warriors who, peering down through

the blue lenses of their helmets, watched the khaki-clad aviators but

made no effort to realign their retortii. "Hero Giles'll skin those

fools alive if he hears of this. Guess we'd better wait a minute:

they'll soon shut off the steam."

Shielding his face from the steam clouds that obliterated all view of

the staircase above, Alden stood watching the billowing steam clouds

in silent awe.

"Terrible, aren't they, Vic?" he remarked. "I've never seen those big

fellows in action. They make the portable variety look like water

pistols."

* * * * *

As the steam barrier showed no signs of abating, an uneasy gleam crept

into Nelson's dark eye, and with jaw grimly set, he cocked the

Winchester and turned with the intention of lodging a complaint at the

next station below; but, to his utter dismay, he beheld bronze armored

figures on the next platform now training their long-muzzled steam gun

across the stair. Even as he sprang back, the deadly white vapor

hissed forth from the second retortii, completely barring further

retreat down the stair. Like an icy flood the chill of impending doom

invaded Nelson's soul. This was no accidental discharge, for with the

slightest change of direction in the deflection of either retortii,

death would descend upon him and his companion.

Swiftly speech became impossible, as the roar of the huge retortii was

deafening; the two were lost in the heart of an opaque cloud which

completely blotted out the copper-hued Atlantean sky. Hot blood surged

into Nelson's head while he became aware of ghostly and stealthy

figures advancing through the shimmering billows of vapor. Up, up,

they came, like dream men, their eyes weird and unreal. Cursing the

treachery of their late host, Nelson and Alden watched dozens upon

dozens of hoplites come swarming up the stairs in solid,

dully-gleaming ranks. Apparently intent to take them prisoners, the

foremost Atlanteans made a rush, giving the American time to fire just

twice.

Unable to retreat, the helpless aviators stood to meet the engulfing

wave of hoplites. Nelson struck out as hard as he could at those

yelling, red-bearded faces, though he knew the effort was hopeless. He

was dimly conscious that Alden, not far away, also fought with the

vigor of despair.

With a sense of savage satisfaction, the dark haired aviator felt his

fist impact solidly into a yelling, sweating face; then something

struck his head and, amid a miniature sunburst, his senseless form

sank limply on the damp stones of the great staircase.

* * * * *

After an interval, the length of which he did not know, Victor Nelson

opened his eyes slowly, for his head throbbed like a savage's war

drum. Uttering a stifled groan he shut the lids to still an

overpowering sense of nausea which gripped him, but a moment later he

made another attempt to discover in what sort of place he found

himself. Gradually, his eyes became accustomed to a curious orange-red

glare beyond a series of bars. Bars? The idea fixed itself in his

benumbed brain; bars meant prison! Yes, those grim blank walls bore

out the assumption. He lay on the damp stone floor of what must be a

fairly spacious cell. Beneath his leather aviator's jacket he

shuddered. "Jail, eh? What a nice place to wake up in!"

A groan from behind him prompted Nelson to painfully raise his head

and look about. He blinked dazedly, meanwhile trying to focus his

eyes, then he heaved a faint sigh of relief as his gaze encountered

the muscular, well-proportioned figure of Richard Alden, who half sat,

half reclined, against one of the grey stone walls, burying a ghastly

pale face between trembling hands.

"You hurt?" To speak, Nelson drew a slightly deeper breath and at once

became conscious of a horrible, throat-wrenching stench. Dimly, he

recalled having once before encountered such an odor; when was it? Oh,

yes; during the Great War when he'd stumbled into a dugout tenanted by

long unburied corpses. A cold finger stabbed at his brain. Corpses.

"Are you hurt, Dick?" he repeated hoarsely.

* * * * *

The lax figure stirred and Alden's blonde head was raised slowly. "I

don't know." His voice came very thickly. "I--I'm still dizzy. What's

happened?"

"Damned if I know; but those bright boys have evidently heaved us into

a calaboose of some kind!"

Nelson, on peering about, had discovered that one end of the cell was

closed only by a series of massive bronze bars; the two other walls

were solid masonry; while the fourth was also solid but fitted with a

small oval door of bronze.

"Calaboose? The hell you say!" Alden coughed feebly. "My God, but that

steam was terrible stuff. I nearly smothered before I got knocked

out."

Slowly, the younger aviator looked about, and suddenly his eyes

widened in an expression of indescribable horror.

"Look!" Alden's voice had died to a shaken whisper. "My God, Nelson,

we're finished! Look at that allosaurus!"

* * * * *

Following the line indicated by the pilot's shaking forefinger, Nelson

peered out through the series of great bars while a shudder shook his

aching body. Though he had seen these fearful monsters on many

occasions, yet it was never from such a position as that in which he

now found himself. To his ears came a sibilant hissing like that of a

thousand serpents; and, quivering in every nerve, he forced his eyes

open once again, to discover that the cell which he and his companion

occupied was but one of a series of cells surrounding a huge square in

which were imprisoned perhaps twenty or thirty of those horrible,

gargoylesque creatures which were the Atlantean dogs of war. Some

thirty-four feet in length, the enormous, slate-grey monsters hopped

leisurely about, their warty hides and huge luminous eyes betraying

their reptilian origin. In shape the allosauri resembled loathsome and

titanic kangaroos as they lumbered awkwardly to and fro, picking

viciously at what appeared to be fragments of human flesh and bones.

While the two prisoners crouched paralyzed with horror, one of the

nightmarish creatures came hopping over and, pressing a head as big as

a steam scoop against the bars, stared in with huge, pale green eyes.

A long minute the ghastly creature remained looking in, clearly

outlined by the orange glow from outside.

* * * * *

The doomed aviators found something fearfully fascinating about those

narrow vertical irises set in pupils the size of dinner plates.

Uttering a deep growl, the allosaurus shuffled nearer, and impatiently

rubbed its huge, bullet head against the bars; then gripped the

ponderous bronze bars with its ridiculously small front legs to shake

the whole grille-work with a savagery that dislocated bits of plaster

and made the metal reverberate. While Nelson and Alden shrank flat

against the far wall, a scarlet tongue at least four feet long

flicked the air but a few feet from their bloodless, sweating visages.

Becoming irritated at the sturdiness of the barrier, the mountainous

reptile tugged harder and hissed, filling the cell with a foul

exhalation that stank like the reeks of smoldering rags.

Nelson's wavering consciousness reeled, and a mad, dreadful fear, like

that a dreamer suffers in the grip of nightmare, invaded his being. He

felt the hairs rising on the nape of his neck.

But, with a squall of rage, the monster abandoned its futile efforts

and leaped away. Feigning indifference, the allosaurus picked up a

half-gnawed skull with its tiny forelegs; and, while the prisoners

watched, it stuffed the head into a maw twice the size of an

elephant's and crunched the gruesome tidbit as easily as a boy would a

walnut. Presently it shuffled off to rejoin the hideous herd in the

center of the court.

"Nice kind of a jail we've been thrown into. Wish I could understand

what's happened." Alden buried his face in his hands. "It kind of

looks as though Altorius had a change of heart."

* * * * *

Nelson replied nothing, but sat staring fixedly out into the horrible

court.

"Somehow, I don't think Altorius would do such a thing," he said at

last. "Let's think back and see if we can't piece this treachery

together."

"Wish I had your faith in the Emperor--but I haven't." Alden's

handsome face twisted itself into a wry smile.

"Let's see, now," persisted Nelson, fingering a square jaw upon which

sprouted a thick growth of reddish bristles. "There was a deputation

of priests to see Altorius yesterday. They were clamoring for the

return of Altara--the Sacred Virgin--and looked pretty mad when he put

them off."

"Maybe this is the private doing of the priests," admitted Alden.

"Anyway, we're in one devil of a fix. There's certainly no way out of

this calaboose--and those damned brutes out there look hungry."

Nelson frowned, deep in thought. "Wish I could find a reasonable

explanation. I really don't think it's Altorius; still, that's what

you get for mixing in on the politics of these forgotten kingdoms."

"But," reminded the other, "you had no choice, old lad. Remember, you

mixed in to save me."

From across the courtyard rang a loud, penetrating shriek of fear that

made the two aviators spring to their feet and rush to the bars.

Peering across the court, they discovered three naked men shrieking

and clinging frantically to the bars of an exactly similar cell.

"What's wrong with them?" demanded Alden as the agonized screams rang

louder still.

"I don't know," was Alden's breathless reply. "But what's that noise?"

A curious metallic clanking sound filled the poisoned air, and for a

moment Nelson remained utterly puzzled. Then, as the noise grew

louder, the allosauri commenced to betray a strange restlessness. They

ceased basking and feeding, and their hideous heads commenced to dart

quickly this way and that.

* * * * *

While the terrific shrieks of the wretches across the court rang to

the copper-hued sky, the two Americans remained in doubt; then all at

once the chill of death gripped their hearts, as they saw the bars of

that cell directly opposite slowly but surely rising! Uttering

heart-rending cries, the doomed prisoners clung frantically to stay

the vanishing barrier separating them from those appalling man-eaters.

But, disdainful of their pitiful efforts, the bronze bars rose

relentlessly with metallic rattlings and janglings from some unseen

mechanism.

Rooted to the floor, both Americans watched the distant grille vanish

into the upper stone-work and heard the ghastly hissing as the

allosauri herd commenced to move forward. Sick and shaken, Nelson

beheld one of the doomed men cling in desperation to the bars; he was

lifted clear of the floor and borne towards the ceiling, meanwhile

venting his terror with such screams as could otherwise have risen

only from an inquisitor's torture chamber.

The tragedy was swiftly completed. Half a dozen of the nearest

allosauri, taller than any giraffes, suddenly sprang forward, their

long, naked tails rising as their gait increased. Snarling horribly,

the vast slate-colored beasts plunged into the cell, terminating

shrieks of mortal terror. Backs broader than bus tops squirmed and

tugged, then one of the loathsome monsters reappeared carrying in its

dripping jaws a mangled, yet struggling victim much as a cat carries a

mouse. In a trice the other allosauri came rushing eagerly up, seeking

to snatch the prey from the first monster.

Nelson stiffened. "Great God! And that's what'll happen to us!"

* * * * *

Weakened by his head wound, and blind with nausea, he stumbled to the

rear of the cell to collapse upon a pile of foul straw, littered with

equipment which the superstitious captors must have condemned together

with the owners.

Nelson sank upon them, then stiffened, for his outflung hand had

encountered a hard, familiar outline. It was a .45 automatic pistol.

A moment's furious search revealed that the captors had missed or not

understood the use of the weapon in Alden's leather flying coat.

"God, but we're lucky," Nelson panted. "The Atlanteans never saw this

pistol of yours. They're only used to my rifle."

Hope lit Alden's features, then faded. "But what good is a .45

against brutes like those? Might at well have a pop gun!"

"Still we're lucky," grunted Nelson, delighted to find the magazine

yet filled. "Can't tell what's ahead. Yes, we're the luckiest--"

He broke off in quick alarm. From overhead had come a premonitory

clang! Somewhere a tackle whined and, with a sense of suffocation,

both men realised that now the bars of _their_ prison were beginning

to creep up into a long slit in the stone ceiling!

Cold fingers of fear clutched Nelson's heart as the terrible

allosauri, their jaws yet dripping redly, wheeled about at the

familiar sound--to stand listening. Up and up crept the ponderous

grille, while the allosauri commenced to shuffle forward, fixing on

their next victims enormous, unblinking green eyes.

* * * * *

While the whole loathsome cell spun about, Victor Nelson forced stiff

fingers to throw off the safety catch as the nearest allosaurus opened

its cavernous mouth in anticipation, displaying an array of curved

teeth, as long and sharp as bayonets. Standing some fifteen feet high

at the shoulder the horrible creature's body was; it all but blotted

out the light. The bars rose inexorably. Now they were waist high....

Now above Nelson's head.... In a moment would come the rush.

Richard Alden stood up straight and squared his shoulders. "Good-by,

Vic," he said, in clear, unafraid tones. "I don't imagine that .45

will even tickle those ghastly brutes."

Nelson nodded. "All over but the cheering," he replied with that

strange, macabre humor which often comes to solace men about to die.

"See you in church." There was an equally gallant lightness to Alden's

reply.

The dark haired pilot, with a curious, detached sense of unreality,

stepped into the middle of the room, the automatic in his hand seeming

no more potent than a water pistol, for a ponderous, lambent eyed

monster was now hopping forward. While minute particles of dust and

dirt rained down from the disappearing barrier, the foremost

allosaurus opened its enormous jaws, uttered an eery scream and

charged straight at the unbarred cell.

Drawing a deep breath, Nelson raised the .45, sighted, and,

remembering his former experience, fired at the enormous right eye. As

in a dream, he felt the recoil. The monster neither slowed nor swerved

in the least, though its great, saucer-like eye disintegrated

horribly. Immediately Nelson swiftly sighted at the other eye and

fired, just as the allosaurus' shadow filled the threshold.

_Crack!_ A swirl of bitter smoke stung the aviator's staring eyes.

He'd hit; he knew it!

* * * * *

Cyclopean moments followed as the blinded monster dashed forward,

missed the circular door, and, butting his head against the stone wall

to the left, fell completely stunned, effectively blocking the doorway

with its huge body. One enormous hind leg, fully ten feet long, and

equipped with three razor-like claws, projected into the cell and

lashed aimlessly back and forth, forcing the two prisoners to dodge

wildly.

There ensued that indescribable kind of a moment when men go mad.

Outside the cell the ravenous herd pounced upon their fallen mate and

with hideous grunts and snarls promptly commenced to tear it apart.

The shaken prisoners realized that the rending jaws would before long

undoubtedly remove the temporary obstacle; but meanwhile the hideous

hissing and the fetid stench of the allosauri breath made the cell a

mad-house.

Gradually, the gigantic carcass at the door commenced to quiver and

roll violently under the ferocious tugs of the eager feasters. A gap

of light appeared over the huge haunches, and, all at once, another

of those terrible heads slipped over the carcass and into the cell.

Again the .45 thundered, lighting the darkened cell with a brief

orange flame. A noise like the furious trumpeting of a dozen elephants

nearly blew Nelson flat as the wounded monster drew back its head, but

the respite promised to be short, for the other reptiles only

re-doubled their horrid, cannibalistic rending of the carcass. When

the barrier was removed there would be a general rush which the shaken

aviators could not hope to stay.

* * * * *

Suddenly, Alden uttered a low shout and pointed to the small, oval

door which had, up to this point, remained securely bolted and shut.

It was swinging gradually open, rimmed with a strong reddish light.

Wide-eyed, and with black hair streaming lank over his forehead,

Nelson, in the act of reloading, swung about to meet this new menace.

Hell! What point was there in prolonging the pitiful struggle? What

was happening?

Slowly, the door swung back, and a rosy glow lit the opening, a glow

that became as strong as the gleam of a spotlight. Then, slowly, a

glittering, green-crested helmet of highly polished bronze appeared,

and, under it, Hero Giles' familiar features, now distorted by a

terrible fear. The blue eyes seemed enormous. "Quickly!" he called.

"Quick or ye are lost!"

Unbelieving of the reprieve, both the aviators stared an instant at

that martial figure clad in brazen armor liberally studded with

enormous diamonds and emeralds, then leaped forward with the speed of

desperation, for from behind came a fierce squalling from the

allosauri. As he darted towards the door Nelson had a glimpse of the

carcass blocking the door commencing to slip sidewise.

Alden was already out and Nelson sped through the door barely in time

to escape the razor-sharp talons of the foremost allosaurus as it

scrambled into the deserted cell with a resounding bellow of

disappointed fury.

CHAPTER VIII

As the door clanged shut, drowning out the allosauri's furious

screams, both aviators, shaken to the depths of their beings, could do

nothing but stare about them in surprise. Completely surrounding and

protecting the exit stood a double rank of hoplites in bronze armor.

Like unreal automata, they remained utterly motionless, fixed in the

various postures of an ancient Macedonian phalanx, their broad backs

gleaming dully in the light of the neon flares. As in a dream, Nelson

recognized on top of each spearsman's casque the graceful Atlantean

military crest--a metal dolphin from the back of which sprouted a

series of bright blue feathers, arranged like a dorsal fin.

"Thank Poseidon, ye still live!" cried Hero Giles, gripping their

hands eagerly. "I had fear for ye, oh my friends."

Nelson grinned. "You cut the rescue act pretty fine, but of course

we're damned grateful. And now,"--eagerly seizing the Hero's

splendidly muscled arm--"in God's name tell us what's happened. Why we

were arrested and--nearly made into allosaurus fodder?"

Hero Giles turned from snapping an order to a subaltern who was

peering down a great, shadowy hallway with a distinctly uneasy manner.

"Much," he said. "Scarcely had ye two departed from Heliopolis than

the priests, mad with rage over Altara's continued captivity, dared to

seize the person of His Splendor and proclaim a regency. Herakles, the

arch-priest is--"

* * * * *

From far down the gloomy, vaulted corridor came a faint sound, rather

like the distant cheering of a crowd. The hoplites, standing about,

turned their helmeted heads and stared uneasily, their brazen armor

glowing dully with each movement.

"I'll tell ye more later, but now--"--Hero Giles' voice took on a

ringing quality like the clash of steel--"there is work to be done. To

rescue ye, oh Hero Nelson, I slew the guards at the lower gate, for

this prison lies in the hands of a caitiff rogue, Hero Edmund, one who

clings to the priestly party. We had best be off lest we be trapped

and slaughtered like rats in a pit."

Very distinctly to the ears of the aviator now came the dull clash of

equipment and the tread of feet.

"Forward! We must hasten to reach the podokos waiting below," cried

Hero Giles, settling his ponderous helmet more squarely on his leonine

head.
