At this paralyzing news, Dorothy's face turned white and Margaret Spencer quietly fainted in her seat.

"Then we can never get back?" asked Dorothy slowly.

At this question, Perkins' self-control gave way and his thin veneer of decency disappeared completely.

"You got us into this whole thing!" he screamed as he leaped at Dorothy with murderous fury gleaming in his pale eyes and his fingers curved into talons. Instead of reaching her, however, he merely sprawled grotesquely in midair, and DuQuesne knocked him clear across the vessel with one powerful blow of his fist.

"Get back there, you cowardly cur," he said evenly. "Even though we are a long way from home, try to remember you're a man, at least. One more break like that and I'll throw you out of the boat. It isn't her fault that we are out here, but our own. The blame for it is a very small matter, anyway; the thing of importance is to get back as soon as possible."

"But how can we get back?" asked Perkins sullenly from the corner where he was crouching, fear in every feature. "The power is gone, the controls are wrecked, and we are hopelessly lost in space."

"Oh, I wouldn't say 'hopelessly,'" returned the other, "I have never been in any situation yet that I couldn't get out of, and I won't be convinced until I am dead that I can't get out of this one. We have two extra power bars, we can fix the board, and if I can't navigate us back close enough to our solar system to find it, I am more of a dub than I think I am. How about a little bite to eat?"

"Show us where it is!" exclaimed Dorothy. "Now that you mention it, I find that I am starved to death."

DuQuesne looked at her keenly.

"I admire your nerve, Miss Vaneman. I didn't suppose that that animal over there would show such a wide streak of yellow, but I was rather afraid that you girls might go to pieces."

"I'm scared blue, of course," Dorothy admitted frankly, "but hysterics won't do any good, and we simply must get back."

"Certainly, we must and we will," stated DuQuesne calmly. "If you like, you might find something for us to eat in the galley there, while I see what I can do with this board that I wrecked with my head. By the way, that cubby-hole there is the apartment reserved for you two ladies. We are in rather cramped quarters, but I think you will find everything you need."

As Dorothy drew herself along the handrail toward the room designated, accompanied by the other girl who, though conscious, had paid little attention to anything around her, she could not help feeling a thrill of admiration for the splendid villain who had abducted her. Calm and cool, always master of himself, apparently paying no attention to the terrible bruises which disfigured half his face and doubtless half his body as well, she admitted to herself that it was only his example, which had enabled her to maintain her self-control in their present plight. As she crawled over Perkins' discarded suit, she remembered that he had not taken any weapons from it. After a rapid glance around to assure herself that she was not being watched, she quickly searched the coat, bringing to light not one, but two pistols, which she thrust into her pocket. She saw with relief that they were regulation army automatics, with whose use she was familiar from much target practise with Seaton.

In the room, which was a miniature of the one she had seen on the Skylark, the girls found clothing, toilet articles, and everything necessary for a long trip. As they were setting themselves to rights, Dorothy electing to stay in her riding suit, they surveyed each other frankly and each was reassured by what she saw. Dorothy saw a girl of twenty-two, of her own stature, with a mass of heavy, wavy black hair. Her eyes, a singularly rich and deep brown, contrasted strangely with the beautiful ivory of her skin. She was normally a beautiful girl, thought Dorothy, but her beauty was marred by suffering and privation. Her naturally slender form was thin, her face was haggard and worn. The stranger broke the silence.

* * * * *

"I'm Margaret Spencer," she began abruptly, "former secretary to His Royal Highness, Brookings of Steel. They swindled my father out of an invention worth millions and he died, broken-hearted. I got the job to see if I couldn't get enough evidence to convict them, and I had quite a lot when they caught me. I had some things that they were afraid to lose, and I had them so well hidden that they couldn't find them, so they kidnapped me to make me give them back. They haven't dared kill me so far for fear the evidence will show up after my death—which it will. However, I will be legally dead before long, and then they know the whole thing will come out, so they have brought me out here to make me talk or kill me. Talking won't do me any good now, though, and I don't believe it ever would have. They would have killed me after they got the stuff back, anyway. So you see I, at least, will never get back to the earth alive."

"Cheer up—we'll all get back safely."

"No, we won't. You don't know that man Perkins—if that is his name. I never heard him called any real name before. He is simply unspeakable—vile—hideous—everything that is base. He was my jailer, and I utterly loathe and despise him. He is mean and underhanded and tricky—he reminds me of a slimy, poisonous snake. He will kill me: I know it."

"But how about Doctor DuQuesne? Surely he isn't that kind of man? He wouldn't let him."

"I've never met him before, but from what I heard of him in the office, he's even worse than Perkins, but in an entirely different way. There's nothing small or mean about him, and I don't believe he would go out of his way to hurt anyone, as Perkins would. But he is absolutely cold and hard, a perfect fiend. Where his interests are concerned, there's nothing under the sun, good or bad, that he won't do. But I'm glad that Perkins had me instead of 'The Doctor,' as they call him. Perkins raises such a bitter personal feeling, that anybody would rather die than give up to him in anything. DuQuesne, however, would have tortured me impersonally and scientifically—cold and self-contained all the while and using the most efficient methods, and I am sure he would have got it out of me some way. He always gets what he goes after."

"Oh, come, Miss Spencer!" Dorothy interrupted the half-hysterical girl. "You're too hard on him. Didn't you see him knock Perkins down when he came after me?"

"Well, maybe he has a few gentlemanly instincts, which he uses when he doesn't lose anything by it. More likely he merely intended to rebuke him for a useless action. He is a firm Pragmatist—anything that is useful is all right, anything that is useless is a crime. More probably yet, he wants you left alive. Of course that is his real reason. He went to the trouble of kidnapping you, so naturally he won't let Perkins or anybody else kill you until he is through with you. Otherwise he would have let Perkins do anything he wanted to with you, without lifting a finger."

"I can't quite believe that," Dorothy replied, though a cold chill struck at her heart as she remembered the inhuman crime attributed to this man, and she quailed at the thought of being in his charge, countless millions of miles from earth, a thought only partly counteracted by the fact that she was now armed. "He has treated us with every consideration so far, let's hope for the best. Anyway, I'm sure that we'll get back safely."

"Why so sure? Have you something up your sleeve?"

"No—or yes, in a way I have, though nothing very definite. I'm Dorothy Vaneman, and I am engaged to the man who discovered the thing that makes this space-car go...."

"That's why they kidnapped you, then—to make him give up all his rights to it. It's like them."

"Yes, I think that's why they did it. But they won't keep me long. Dick Seaton will find me, I know. I feel it."

"But that's exactly what they want!" cried Margaret excitedly. "In my spying around I heard a little about this very thing—the name Seaton brings it to my mind. His car is broken in some way, so that it will kill him the first time he tries to run it."

"That's where they underestimated Dick and his partner. You have heard of Martin Crane, of course?"

"I think I heard his name mentioned in the office, together with Seaton's, but that's all."

"Well, besides other things, Martin is quite a wonderful mechanic, and he found out that our Skylark was spoiled. So they built another one, a lot bigger, and I am sure that they are following us, right now."

"But how can they possibly follow us, when we are going so fast and are so far away?" queried the other girl, once more despondent.

"I don't quite know, but I do know that Dick will find a way. He's simply wonderful. He knows more now than that Doctor DuQuesne will ever learn in all his life, and he will find us in a few days. I feel it in my bones. Besides, I picked Perkins' pockets of these two pistols. Can you shoot an automatic?"

"Yes," replied the other girl, as she seized one of the guns, assured herself that its magazine was full, and slipped it into her pocket. "I used to practise a lot with my father's. This makes me feel a whole lot better. And call me Peggy, won't you? It will seem good to hear my name again. After what I've been through lately, even this trip will be a vacation for me."

"Well, then, cheer up, Peggy dear, we're going to be great friends. Let's go get us all something to eat. I'm simply starved, and I know you are, too."

* * * * *

The presence of the pistol in her pocket and Dorothy's unwavering faith in her lover, lifted the stranger out of the mood of despair into which the long imprisonment, the brutal treatment, and the present situation had plunged her, and she was almost cheerful as they drew themselves along the hand-rail leading to the tiny galley.

"I simply can't get used to the idea of nothing having any weight—look here!" laughed Dorothy, as she took a boiled ham out of the refrigerator and hung it upon an imaginary hook in the air, where it remained motionless. "Doesn't it make you feel funny?"

"It is a queer sensation. I feel light, like a toy balloon, and I feel awfully weird inside. If we have no weight, why does it hurt so when we bump into anything? And when you throw anything, like the Doctor did Perkins, why does it hit as hard as ever?"

"It's mass or inertia or something like that. A thing has it everywhere, whether it weighs anything or not. Dick explained it all to me. I understood it when he told me about it, but I'm afraid it didn't sink in very deep. Did you ever study physics?"

"I had a year of it in college, but it was more or less of a joke. I went to a girls' school, and all we had to do in physics was to get the credit; we didn't have to learn it."

"Me too. Next time I go to school I'm going to Yale or Harvard or some such place, and I'll learn so much mathematics and science that I'll have to wear a bandeau to keep my massive intellect in place."

During this conversation they had prepared a substantial luncheon and had arranged it daintily upon two large trays, in spite of the difficulty caused by the fact that nothing would remain in place by its own weight. The feast prepared, Dorothy took her tray from the table as carefully as she could, and saw the sandwiches and bottles start to float toward the ceiling. Hastily inverting the tray above the escaping viands, she pushed them back down upon the table. In doing so she lifted herself clear from the floor, as she had forgotten to hold herself down.

"What'll we do, anyway?" she wailed when she had recovered her position. "Everything wants to fly all over the place!"

"Put another tray on top of it and hold them together," suggested Margaret. "I wish we had a birdcage. Then we could open the door and grab a sandwich as it flies out."

By covering the trays the girls finally carried the luncheon out into the main compartment, where they gave DuQuesne and Perkins one of the trays and all fell to eating hungrily. DuQuesne paused with a glint of amusement in his one sound eye as he saw Dorothy trying to pour ginger ale out of a bottle.

"It can't be done, Miss Vaneman. You'll have to drink it through a straw. That will work, since our air pressure is normal. Be careful not to choke on it, though; your swallowing will have to be all muscular out here. Gravity won't help you. Or wait a bit—I have the control board fixed and it will be a matter of only a few minutes to put in another bar and get enough acceleration to take the place of gravity."

He placed one of the extra power bars in the chamber and pushed the speed lever into the first notch, and there was a lurch of the whole vessel as it swung around the bar so that the floor was once more perpendicular to it. He took a couple of steps, returned, and advanced the lever another notch.

"There that's about the same as gravity. Now we can act like human beings and eat in comfort."

"That's a wonderful relief, Doctor!" cried Dorothy. "Are we going back toward the earth?"

"Not yet. I reversed the bar, but we will have to use up all of this one before we can even start back. Until this bar is gone we will merely be slowing down."

* * * * *

As the meal progressed, Dorothy noticed that DuQuesne's left arm seemed almost helpless, and that he ate with great difficulty because of his terribly bruised face. As soon as they had removed the trays she went into her room, where she had seen a small medicine chest, and brought out a couple of bottles.

"Lie down here, Doctor DuQuesne," she commanded. "I'm going to apply a little first-aid to the injured. Arnica and iodine are all I can find, but they'll help a little."

"I'm all right," began the scientist, but at her imperious gesture he submitted, and she bathed his battered features with the healing lotion and painted the worst bruises with iodine.

"I see your arm is lame. Where does it hurt?"

"Shoulder's the worst. I rammed it through the board when we started out."

He opened his shirt at the throat and bared his shoulder, and Dorothy gasped—as much at the size and power of the muscles displayed, as at the extent and severity of the man's injuries. Stepping into the gallery, she brought out hot water and towels and gently bathed away the clotted blood that had been forced through the skin.

"Massage it a little with the arnica as I move the arm," he directed coolly, and she did so, pityingly. He did not wince and made no sign of pain, but she saw beads of perspiration appear upon his face, and wondered at his fortitude.

"That's fine," he said gratefully as she finished, and a peculiar expression came over his face. "It feels one hundred per cent better already. But why do you do it? I should think you would feel like crowning me with that basin instead of playing nurse."

"Efficiency," she replied with a smile. "I'm taking a leaf out of your own book. You are our chief engineer, you know, and it won't do to have you laid up."

"That's a logical explanation, but it doesn't go far enough," he rejoined, still studying her intently. She did not reply, but turned to Perkins.

"How are you, Mr. Perkins? Do you require medical attention?"

"No," growled Perkins from the seat in which he had crouched immediately after eating. "Keep away from me, or I'll cut your heart out!"

"Shut up!" snapped DuQuesne. "Remember what I said?"

"I haven't done anything," snarled the other.

"I said I would throw you out if you made another break," DuQuesne informed him evenly, "and I meant it. If you can't talk decently, keep still. Understand that you are to keep off Miss Vaneman, words and actions. I am in charge of her, and I will put up with no interference whatever. This is your last warning."

"How about Spencer, then?"

"I have nothing to say about her, she's not mine," responded DuQuesne with a shrug.

An evil light appeared in Perkins' eyes and he took out a wicked-looking knife and began to strop it carefully upon the leather of the seat, glaring at his victim the while.

"Well, I have something to say...." blazed Dorothy, but she was silenced by a gesture from Margaret, who calmly took the pistol from her pocket, jerked the slide back, throwing a cartridge into the chamber, and held the weapon up on one finger, admiring it from all sides.

* * * * *

"Don't worry about his knife. He has been sharpening it for my benefit for the last month. He doesn't mean anything by it."

At this unexpected show of resistance, Perkins stared at her for an instant, then glanced at his coat.

"Yes, this was yours, once. You needn't bother about picking up your coat, they're both gone. You might be tempted to throw that knife, so drop it on the floor and kick it over to me before I count three.

"One." The heavy pistol steadied into line with his chest and her finger tightened on the trigger.

"Two." He obeyed and she picked up the knife. He turned to DuQuesne, who had watched the scene unmoved, a faint smile upon his saturnine face.

"Doctor!" he cried, shaking with fear. "Why don't you shoot her or take that gun away from her? Surely you don't want to see me murdered?"

"Why not?" replied DuQuesne calmly. "It is nothing to me whether she kills you or you kill her. You brought it on yourself by your own carelessness. Any man with brains doesn't leave guns lying around within reach of prisoners, and a blind man could have seen Miss Vaneman getting your hardware."

"You saw her take them and didn't warn me?" croaked Perkins.

"Why should I warn you? If you can't take care of your own prisoner she earns her liberty, as far as I am concerned. I never did like your style, Perkins, especially your methods of handling—or rather mishandling—women. You could have made her give up the stuff she recovered from that ass Brookings inside of an hour, and wouldn't have had to kill her afterward, either."

"How?" sneered the other. "If you are so good at that kind of thing, why didn't you try it on Seaton and Crane?"

"There are seven different methods to use on a woman like Miss Spencer, each of which will produce the desired result. The reason I did not try them on either Seaton or Crane is that they would have failed. Your method of indirect action is probably the only one that will succeed. That is why I adopted it."

"Well, what are you going to do about it?" shrieked Perkins. "Are you going to sit there and lecture all day?"

"I am going to do nothing whatever," answered the scientist coldly. "If you had any brains you would see that you are in no danger. Miss Spencer will undoubtedly kill you if you attack her—not otherwise. That is an Anglo-Saxon weakness."

"Did you see me take the pistols?" queried Dorothy.

"Certainly. I'm not blind. You have one of them in your right coat pocket now."

"Then why didn't you, or don't you, try to take it away from me?" she asked in wonder.

"If I had objected to your having them, you would never have got them. If I didn't want you to have a gun now, I would take it away from you. You know that, don't you?" and his black eyes stared into her violet ones with such calm certainty of his ability that she felt her heart sink.

"Yes," she admitted finally, "I believe you could—that is, unless I were angry enough to shoot you."

"That wouldn't help you. I can shoot faster and straighter than you can, and would shoot it out of your hand. However, I have no objection to your having the gun, since it is no part of my plan to offer you any further indignity of any kind. Even if you had the necessary coldness of nerve or cruelty of disposition—of which I have one, Perkins the other, and you neither—you wouldn't shoot me now, because you can't get back to the earth without me. After we get back I will take the guns away from both of you if I think it desirable. In the meantime, play with them all you please."

"Has Perkins any more knives or guns or things in his room?" demanded Dorothy.

"How should I know?" indifferently; then, as both girls started for Perkins' room he ordered brusquely:

"Sit down, Miss Vaneman. Let them fight it out. Perkins has his orders to lay off you—you lay off him. I'm not taking any chances of getting you hurt, that's one reason I wanted you armed. If he gets gay, shoot him; otherwise, hands off completely."

Dorothy threw up her head in defiance, but meeting his cold stare she paused irresolutely and finally sat down, biting her lips in anger, while the other girl went on.

"That's better. She doesn't need any help to whip that yellow dog. He's whipped already. He never would think of fighting unless the odds were three to one in his favor."

* * * * *

When Margaret had returned from a fruitless search of Perkins' room and had assured herself that he had no more weapons concealed about his person, she thrust the pistol back into her pocket and sat down.

"That ends that," she declared. "I guess you will be good now, won't you, Mr. Perkins?"

"Yes," that worthy muttered. "I have to be, now that you've got the drop on me and DuQuesne's gone back on me. But wait until we get back! I'll get you then, you...."

"Stop right there!" sharply. "There's nothing I would rather do than shoot you right now, if you give me the slightest excuse, such as that name you were about to call me. Now go ahead!"

DuQuesne broke the silence that followed.

"Well, now that the battle is over, and since we are fed and rested, I suggest that we slow down a bit and get ready to start back. Pick out comfortable seats, everybody, and I'll shoot a little more juice through that bar."

Seating himself before the instrument board, he advanced the speed lever slowly until nearly three-quarters of the full power was on, as much as he thought the others could stand.

For sixty hours he drove the car, reducing the acceleration only at intervals during which they ate and walked about their narrow quarters in order to restore the blood to circulation in their suffering bodies. The power was not reduced for sleep; everyone slept as best he could.

Dorothy and Margaret talked together at every opportunity, and a real intimacy grew up between them. Perkins was for the most part sullenly quiet, knowing himself despised by all the others and having no outlet here for his particular brand of cleverness. DuQuesne was always occupied with his work and only occasionally addressed a remark to one or another of the party, except during meals. At those periods of general recuperation, he talked easily and well upon many topics. There was no animosity in his bearing nor did he seem to perceive any directed toward himself, but when any of the others ventured to infringe upon his ideas of how discipline should be maintained, DuQuesne's reproof was merciless. Dorothy almost liked him, but Margaret insisted that she considered him worse than ever.

When the bar was exhausted, DuQuesne lifted the sole remaining cylinder into place.

"We should be nearly stationary with respect to the earth," he remarked. "Now we will start back."

"Why, it felt as though we were picking up speed for the last three days!" exclaimed Margaret.

"Yes, it feels that way because we have nothing to judge by. Slowing down in one direction feels exactly like starting up in the opposite one. There is no means of knowing whether we are standing still, going away from the earth, or going toward it, since we have nothing stationary upon which to make observations. However, since the two bars were of exactly the same size and were exerted in opposite directions except for a few minutes after we left the earth, we are nearly stationary now. I will put on power until this bar is something less than half gone, then coast for three or four days. By the end of that time we should be able to recognize our solar system from the appearance of the fixed stars."

He again advanced the lever, and for many hours silence filled the car as it hurtled through space. DuQuesne, waking up from a long nap, saw that the bar no longer pointed directly toward the top of the ship, perpendicular to the floor, but was inclined at a sharp angle. He reduced the current, and felt the lurch of the car as it swung around the bar, increasing the angle many degrees. He measured the angle carefully and peered out of all the windows on one side of the car. Returning to the bar after a time, he again measured the angle, and found that it had increased greatly.

"What's the matter, Doctor DuQuesne?" asked Dorothy, who had also been asleep.

"We are being deflected from our course. You see the bar doesn't point straight up any more? Of course the direction of the bar hasn't changed, the car has swung around it."

"What does that mean?"

"We have come close enough to some star so that its attraction swings the bottom of the car around. Normally, you know, the bottom of the car follows directly behind the bar. It doesn't mean much yet except that we are being drawn away from our straight line, but if the attraction gets much stronger it may make us miss our solar system completely. I have been looking for the star in question, but can't see it yet. We'll probably pull away from it very shortly."

* * * * *

He threw on the power, and for some time watched the bar anxiously, expecting to see it swing back into the vertical, but the angle continually increased. He again reduced the current and searched the heavens for the troublesome body.

"Do you see it yet?" asked Dorothy with concern.

"No, there's apparently nothing near enough to account for all this deflection."

He took out a pair of large night-glasses and peered through them for several minutes.

"Good God! It's a dead sun, and we're nearly onto it! It looks as large as our moon!"

Springing to the board, he whirled the bar into the vertical. He took down a strange instrument, went to the bottom window, and measured the apparent size of the dark star. Then, after cautioning the rest of the party to sit tight, he advanced the lever farther than it had been before. After half an hour he again slackened the pace and made another observation, finding to his astonishment that the dark mass had almost doubled its apparent size! Dorothy, noting his expression, was about to speak, but he forestalled her.

"We lost ground, instead of gaining, that spurt," he remarked, as he hastened to his post. "It must be inconceivably large, to exert such an enormous attractive force at this distance. We'll have to put on full power. Hang onto yourselves as best you can."

He then pushed the lever out to its last notch and left it there until the bar was nearly gone, only to find that the faint disk of the monster globe was even larger than before, being now visible to the unaided eye. Revived, the three others saw it plainly—a great dim circle, visible as is the dark portion of the new moon—and, the power shut off, they felt themselves falling toward it with sickening speed. Perkins screamed with mad fear and flung himself grovelling upon the floor. Margaret, her nerves still unstrung, clutched at her heart with both hands. Dorothy, though her eyes looked like great black holes in her white face, looked DuQuesne in the eye steadily.

"This is the end, then?"

"Not yet," he replied in a calm and level voice. "The end will not come for a good many hours, as I have calculated that it will take at least two days, probably more, to fall the distance we have to go. We have all that time in which to think out a way of escape."

"Won't the outer repulsive shell keep up from striking it, or at least break the force of our fall?"

"No. It was designed only as protection from meteorites and other small bodies. It is heavy enough to swing us away from a small planet, but it will be used up long before we strike."

He lighted a cigarette and sat at case, as though in his own study, his brow wrinkled in thought as he made calculations in his notebook. Finally he rose to his feet.

"There's only one chance that I can see. That is to gather up every scrap of copper we have and try to pull ourselves far enough out of line so that we will take an hyperbolic orbit around that body instead of falling into it."

"What good will that do us?" asked Margaret, striving for self-control. "We will starve to death finally, won't we?"

"Not necessarily. That will give us time to figure out something else."

"You won't have to figure out anything else, Doctor," stated Dorothy positively. "If we miss that moon, Dick and Martin will find us before very long."

"Not in this life. If they tried to follow us, they're both dead before now."

"That's where even you are wrong!" she flashed at him. "They knew you were wrecking our machine, so they built another one, a good one. And they know a lot of things about this new metal that you have never dreamed of, since they were not in the plans you stole."

* * * * *

DuQuesne went directly to the heart of the matter, paying no attention to her barbed shafts.

"Can they follow us through space without seeing us?" he demanded.

"Yes—or at least, I think they can."

"How do they do it?"

"I don't know—I wouldn't tell you if I did."

"You'll tell if you know," he declared, his voice cutting like a knife. "But that can wait until after we get out of this. The thing to do now is to dodge that world."

He searched the vessel for copper, ruthlessly tearing out almost everything that contained the metal, hammering it flat and throwing it into the power-plant. He set the bar at right angles to the line of their fall and turned on the current. When the metal was exhausted, he made another series of observations upon the body toward which they were falling, and reported quietly:

"We made a lot of distance, but not enough. Everything goes in, this time."

He tore out the single remaining light-wire, leaving the car in darkness save for the diffused light of his electric torch, and broke up the only remaining motor. He then took his almost priceless Swiss watch, his heavy signet ring, his scarf pin, and the cartridges from his pistol, and added them to the collection. Flashing his lamp upon Perkins, he relieved him of everything he had which contained copper.

"I think I have a few pennies in my pocketbook," suggested Dorothy.

"Get 'em," he directed briefly, and while she was gone he searched Margaret, without result save for the cartridges in her pistol, as she had no jewelry remaining after her imprisonment. Dorothy returned and handed him everything she had found.

"I would like to keep this ring," she said slowly, pointing to a slender circlet of gold set with a solitaire diamond, "if you think there is any chance of us getting clear."

"Everything goes that has any copper in it," he said coldly, "and I am glad to see that Seaton is too good a chemist to buy any platinum jewelry. You may keep the diamond, though," as he wrenched the jewel out of its setting and returned it to her.

He threw all the metal into the central chamber and the vessel gave a tremendous lurch as the power was again applied. It was soon spent, however, and after the final observation, the others waiting in breathless suspense for him to finish his calculations, he made his curt announcement.

"Not enough."

Perkins, his mind weakened by the strain of the last few days, went completely insane at the words. With a wild howl he threw himself at the unmoved scientist, who struck him with the butt of his pistol as he leaped, the mighty force of DuQuesne's blow crushing his skull like an eggshell and throwing him backward to the opposite side of the vessel. Margaret lay in her seat in a dead faint. Dorothy and DuQuesne looked at each other in the feeble light of the torch. To the girl's amazement, the man was as calm as though he were safe in his own house, and she made a determined effort to hold herself together.

"What next, Doctor DuQuesne?"

"I don't know. We have a couple of days yet, at least. I'll have to study awhile."

"In that time Dick will find us, I know."

"Even if they do find us in time, which I doubt, what good will it do? It simply means that they will go with us instead of saving us, for of course they can't pull away, since we couldn't. I hope they don't find us, but locate this star in time to keep away from it."

"Why?" she gasped. "You have been planning to kill both of them! I should think you would be delighted to take them with us?"

"Far from it. Please try to be logical. I intended to remove them because they stood in the way of my developing this new metal. If I am to be out of the way—and frankly, I see very little chance of getting out of this—I hope that Seaton goes ahead with it. It is the greatest discovery the world has ever known, and if both Seaton and I, the only two men in the world who know how to handle it, drop out, it will be lost for perhaps hundreds of years."

"If Dick's finding us means that he must go, too, of course I hope that he won't find us, but I don't believe that. I simply know that he could get us away from here."

She continued more slowly, almost speaking to herself, her heart sinking with her voice:

"He is following us, and he won't stop even if he does see this dead star and knows that he can't get away. We will die together."

"There's no denying the fact that our situation is critical, but you know a man isn't dead until after his heart stops beating. We have two whole days yet, and in that time, I can probably dope out some way of getting away from here."

"I hope so," she replied, keeping her voice from breaking only by a great effort. "But go ahead with your doping. I'm worn out." She drew herself down upon one of the seats and stared at the ceiling, fighting to restrain an almost overpowering impulse to scream.

Thus the hours wore by—Perkins dead; Margaret still unconscious; Dorothy lying in her seat, her thoughts a formless prayer, buoyed up only by her faith in God and in her lover; DuQuesne self-possessed, smoking innumerable cigarettes, his keen mind grappling with its most desperate problem, grimly fighting until the very last instant of life—while the powerless space-car fell with an appalling velocity, faster and faster; falling toward that cold and desolate monster of the heaven.



CHAPTER X

The Rescue

Seaton and Crane drove the Skylark in the direction indicated by the unwavering object-compass with the greatest acceleration they could stand, each man taking a twelve-hour watch at the instrument board.

Now, indeed, did the Skylark justify the faith of her builders, and the two inventors, with an exultant certainty of their success, flew out beyond man's wildest imaginings. Had it not been for the haunting fear for Dorothy's safety, the journey would have been one of pure triumph, and even that anxiety did not prevent a profound joy in the enterprise.

"If that misguided mutt thinks he can pull off a stunt like that and get away with it, he's got another think coming," asserted Seaton, after making a reading on the other car after several days of the flight. "He went off half-cocked this time, for sure, and we've got him foul. We'd better put on some negative pretty soon hadn't we, Mart? Only a little over a hundred light-years now."

Crane nodded agreement and Seaton continued:

"It'll take as long to stop, of course, as it has taken to get out here, and if we ram them—GOOD NIGHT! Let's figure it out as nearly as we can."

They calculated their own speed, and that of the other vessel, as shown by the various readings taken, and applied just enough negative acceleration to slow the Skylark down to the speed of the other space-car when they should come up with it. They smiled at each other in recognition of the perfect working of the mechanism when the huge vessel had spun, with a sickening lurch, through a complete half-circle, the instant the power was reversed. Each knew that they were actually traveling in a direction that to them seemed "down," but with a constantly diminishing velocity, even though they seemed to be still going "up" with an increasing speed.

Until nearly the end of the calculated time the two took turns as before, but as the time of meeting drew near both men were on the alert, taking readings on the object-compass every few minutes. Finally Crane announced:

"We are almost on them, Dick. They are so close that it is almost impossible to time the needle—less than ten thousand miles."

Seaton gradually increased the retarding force until the needle showed that they were very close to the other vessel and maintaining a constant distance from it. He then shut off the power, and both men hurried to the bottom window to search for the fleeing ship with their powerful night-glasses. They looked at each other in amazement as they felt themselves falling almost directly downward, with an astounding acceleration.

"What do you make of it, Dick?" asked Crane calmly, as he brought his glasses to his eyes and stared out into the black heavens, studded with multitudes of brilliant and unfamiliar stars.

"I don't make it at all, Mart. By the feel, I should say we were falling toward something that would make our earth look like a pin-head. I remember now that I noticed that the bus was getting a little out of plumb with the bar all this last watch. I didn't pay much attention to it, as I couldn't see anything out of the way. Nothing but a sun could be big enough to raise all this disturbance, and I can't see any close enough to be afraid of, can you?"

"No, and I cannot see the Steel space-car, either. Look sharp."

"Of course," Seaton continued to argue as he peered out into the night, "it is theoretically possible that a heavenly body can exist large enough so that it could exert even this much force and still appear no larger than an ordinary star, but I don't believe it is probable. Give me three or four minutes of visual angle and I'll believe anything, but none of these stars are big enough to have any visual angle at all. Furthermore...."

"There is at least half a degree of visual angle!" broke in his friend intensely. "Just to the left of that constellation that looks so much like a question mark. It is not bright, but dark, like a very dark moon—barely perceptible."

Seaton pointed his glass eagerly in the direction indicated.

"Great Cat!" he ejaculated. "I'll say that's some moon! Wouldn't that rattle your slats? And there's DuQuesne's bus, too, on the right edge. Get it?"

As they stood up, Seaton's mood turned to one of deadly earnestness, and a grave look came over Crane's face as the seriousness of their situation dawned upon them. Trained mathematicians both, they knew instantly that that unknown world was of inconceivable mass, and that their chance of escape was none too good, even should they abandon the other craft to its fate. Seaton stared at Crane, his fists clenched and drops of perspiration standing on his forehead. Suddenly, with agony in his eyes and in his voice, he spoke.

"Mighty slim chance of getting away if we go through with it, old man.... Hate like the devil.... Have no right to ask you to throw yourself away, too."

"Enough of that, Dick. You had nothing to do with my coming: you could not have kept me away. We will see it through."

Their hands met in a fierce clasp, broken by Seaton, as he jumped to the levers with an intense:

"Well, let's get busy!"

In a few minutes they had reduced the distance until they could plainly see the other vessel, a small black circle against the faintly luminous disk. As it leaped into clear relief in the beam of his powerful searchlight, Seaton focused the great attractor upon the fugitive car and threw in the lever which released the full force of that mighty magnet, while Crane attracted the attention of the vessel's occupants by means of a momentary burst of solid machine-gun bullets, which he knew would glance harmlessly off the steel hull.

* * * * *

After an interminable silence, DuQuesne drew himself out of his seat. He took a long inhalation, deposited the butt of his cigarette carefully in his ash tray, and made his way to his room. He returned with three heavy fur suits provided with air helmets, two of which he handed to the girls, who were huddled in a seat with their arms around each other. These suits were the armor designed by Crane for use in exploring the vacuum and the intense cold of dead worlds. Air-tight, braced with fine steel netting, and supplied with air at normal pressure from small tanks by automatic valves, they made their wearers independent of surrounding conditions of pressure and temperature.

"The next thing to do," DuQuesne stated calmly, "is to get the copper off the outside of the ship. That is the last resort, as it robs us of our only safeguard against meteorites, but this is the time for last-resort measures. I'm going after that copper. Put these suits on, as our air will leave as soon as I open the door, and practically an absolute vacuum and equally absolute zero will come in."

As he spoke, the ship was enveloped in a blinding glare and they were thrown flat as the vessel slowed down in its terrific fall. The thought flashed across DuQuesne's mind that they had already entered the atmosphere of that monster globe and were being slowed down and set afire by its friction, but he dismissed it as quickly as it had come—the light in that case would be the green of copper, not this bluish-white. His next thought was that there had been a collision of meteors in the neighborhood, and that their retardation was due to the outer coating. While these thoughts were flickering through his mind, they heard an insistent metallic tapping, which DuQuesne recognized instantly.

"A machine-gun!" he blurted in amazement. "How in...."

"It's Dick!" screamed Dorothy, with flashing eyes. "He's found us, just as I knew he would. You couldn't beat Dick and Martin in a thousand years!"

The tension under which they had been laboring so long suddenly released, the two girls locked their arms around each other in a half-hysterical outburst of relief. Margaret's meaningless words and Dorothy's incoherent praises of her lover and Crane mingled with their racking sobs as each fought to recover self-possession.

DuQuesne had instantly mounted to the upper window. Throwing back the cover, he flashed his torch rapidly. The glare of the searchlight was snuffed out and he saw a flashing light spell out in dots and dashes:

"Can you read Morse?"

"Yes," he signalled back. "Power gone, drifting into...."

"We know it. Will you resist?"

"No."

"Have you fur pressure-suits?"

"Yes."

"Put them on. Shut off your outer coating. Will touch so your upper door against our lower. Open, transfer quick."

"O. K."

* * * * *

Hastily returning to the main compartment, he briefly informed the girls as to what had happened. All three donned the suits and stationed themselves at the upper opening. Rapidly, but with unerring precision, the two ships were brought into place and held together by the attractor. As the doors were opened, there was a screaming hiss as the air of the vessels escaped through the narrow crack between them. The passengers saw the moisture in the air turn into snow, and saw the air itself first liquefy and then freeze into a solid coating upon the metal around the orifices at the touch of the frightful cold outside—the absolute zero of interstellar space, about four hundred sixty degrees below zero in the every-day scale of temperature. The moisture of their breath condensed upon the inside of the double glasses of their helmets, rendering sight useless.



Dorothy pushed the other girl ahead of her. DuQuesne seized her and tossed her lightly through the doorway in such a manner that she would not touch the metal, which would have frozen instantly anything coming into contact with it. Seaton was waiting. Feeling a woman's slender form in his arms, he crushed her to him in a mighty embrace, and was astonished to feel movements of resistance, and to hear a strange, girlish voice cry out:

"Don't! It's me! Dorothy's next!"

Releasing her abruptly, he passed her on to Martin and turned just in time to catch his sweetheart, who, knowing that he would be there and recognizing his powerful arms at the first touch, returned his embrace with a fierce intensity which even he had never suspected that she could exert. They stood motionless, locked in each other's arms, while DuQuesne dove through the opening and snapped the door shut behind him.

The air-pressure and temperature back to normal, the cumbersome suits were hastily removed, and Seaton's lips met Dorothy's in a long, clinging caress. DuQuesne's cold, incisive voice broke the silence.

"Every second counts. I would suggest that we go somewhere."

"Just a minute!" snapped Crane. "Dick, what shall we do with this murderer?"

Seaton had forgotten DuQuesne utterly in the joy of holding his sweetheart in his arms, but at his friend's words, he faced about and his face grew stern.

"By rights, we ought to chuck him back into his own tub and let him go to the devil," he said savagely, doubling his fists and turning swiftly.

"No, no, Dick," remonstrated Dorothy, seizing his arm. "He treated us very well, and saved my life once. Anyway, you mustn't kill him."

"No, I suppose not," grudgingly assented her lover, "and I won't, either, unless he gives me at least half an excuse."

"We might iron him to a post?" suggested Crane, doubtfully.

"I think there's a better way," replied Seaton. "He may be able to work his way. His brain hits on all twelve, and he's strong as a bull. Our chance of getting back isn't a certainty, as you know." He turned to DuQuesne.

"I've heard that your word is good."

"It has never been broken."

"Will you give your word to act as one of the party, for the good of us all, if we don't iron you?"

"Yes—until we get back to the earth. Provided, of course, that I reserve the right to escape at any time between now and then if I wish to and can do so without injuring the vessel or any member of the party in any way."

"Agreed. Let's get busy—we're altogether too close to that dud there to suit me. Sit tight, everybody, we're on our way!" he cried, as he turned to the board, applied one notch of power, and shut off the attractor. The Skylark slowed down a trifle in its mad fall, the other vessel continued on its way—a helpless hulk, manned by a corpse, falling to destruction upon the bleak wastes of a desert world.

"Hold on!" said DuQuesne sharply. "Your power is the same as mine was, in proportion to your mass, isn't it?"

"Yes."

"Then our goose is cooked. I couldn't pull away from it with everything I had, couldn't even swing out enough to make an orbit, either hyperbolic or elliptical around it. With a reserve bar you will be able to make an orbit, but you can't get away from it."

"Thanks for the dope. That saves our wasting some effort. Our power-plant can be doubled up in emergencies, thanks to Martin's cautious old bean. We'll simply double her up and go away from here."

* * * * *

"There is one thing we didn't consider quite enough," said Crane, thoughtfully. "I started to faint back there before the full power of even one motor was in use. With the motor doubled, each of us will be held down by a force of many tons—we would all be helpless."

"Yes," added Dorothy, with foreboding in her eyes, "we were all unconscious on the way out, except Dr. DuQuesne."

"Well, then, Blackie and I, as the huskiest members of the party, will give her the juice until only one of us is left with his eyes open. If that isn't enough to pull us clear, we'll have to give her the whole works and let her ramble by herself after we all go out. How about it, Blackie?" unconsciously falling into the old Bureau nickname. "Do you think we can make it stop at unconsciousness with double power on?"

DuQuesne studied the two girls carefully.

"With oxygen in the helmets instead of air, we all may be able to stand it. These special cushions keep the body from flattening out, as it normally would under such a pressure. The unconsciousness is simply a suffocation caused by the lateral muscles being unable to lift the ribs—in other words, the air-pumps aren't strong enough for the added work put upon them. At least we stand a chance this way. We may live through the pressure while we are pulling away, and we certainly shall die if we don't pull away."

After a brief consultation, the men set to work with furious haste. While Crane placed extra bars in each of the motors and DuQuesne made careful observations upon the apparent size of the now plainly visible world toward which they were being drawn so irresistibly, Seaton connected the helmets with the air-and oxygen-tanks through a valve upon the board, by means of which he could change at will the oxygen content of the air they breathed. He then placed the strange girl, who seemed dazed by the frightful sensation of their never-ending fall, upon one of the seats, fitted the cumbersome helmet upon her head, strapped her carefully into place, and turned to Dorothy. In an instant they were in each other's arms. He felt her labored breathing and the wild beating of her heart, pressed so closely to his, and saw the fear of the unknown in the violet depths of her eyes, but she looked at him unflinchingly.

"Dick, sweetheart, if this is good-bye...."

He interrupted her with a kiss.

"It isn't good-bye yet, Dottie mine. This is merely a trial effort, to see what we will have to do to get away. Next time will be the time to worry."

"I'm not worried, really ... but in case ... you see ... I ... we ..."

The gray eyes softened and misted over as he pressed his cheek to hers.

"I understand, sweetheart," he whispered. "This is not good-bye, but if we don't pull through we'll go together, and that is what we both want."

As Crane and DuQuesne finished their tasks, Seaton fitted his sweetheart's helmet, placed her tenderly upon the seat, buckled the heavy restraining straps about her slender body, and donned his own helmet. He took his place at the main instrument board, DuQuesne stationing himself at the other.

"What did you read on it, Blackie?" asked Seaton.

"Two degrees, one minute, twelve seconds diameter," replied DuQuesne. "Altogether too close for comfort. How shall we apply the power? One of us must stay awake, or we'll go on as long as the bars last."

"You put on one notch, then I'll put on one. We can feel the bus jump with each notch. We'll keep it up until one of us is so far gone that he can't raise the bar—the one that raises last will have to let the ship run for thirty minutes or an hour, then cut down his power. Then the other fellow will revive and cut his off, for an observation. How's that?"

"All right."

* * * * *

They took their places, and Seaton felt the vessel slow down in its horrible fall as DuQuesne threw his lever into the first notch. He responded instantly by advancing his own, and notch after notch the power applied to the ship by the now doubled motor was rapidly increased. The passengers felt their suits envelope them and began to labor for breath. Seaton slowly turned the mixing valve, a little with each advance of his lever, until pure oxygen flowed through the pipes. The power levers had moved scarcely half of their range, yet minutes now intervened between each advance instead of seconds, as at the start.

As each of the two men was determined that he would make the last advance, the duel continued longer than either would have thought possible. Seaton made what he thought his final effort and waited—only to feel, after a few minutes, the upward surge telling him that DuQuesne was still able to move his lever. His brain reeled. His arm seemed paralyzed by its own enormous weight, and felt as though it, the rolling table upon which it rested, and the supporting framework were so immovably welded together that it was impossible to move it even the quarter-inch necessary to operate the ratchet-lever. He could not move his body, which was oppressed by a sickening weight. His utmost efforts to breathe forced only a little of the life-giving oxygen into his lungs, which smarted painfully at the touch of the undiluted gas, and he felt that he could not long retain consciousness under such conditions. Nevertheless, he summoned all his strength and advanced the lever one more notch. He stared at the clock-face above his head, knowing that if DuQuesne could advance his lever again he would lose consciousness and be beaten. Minute after minute went by, however, and the acceleration of the ship remained constant. Seaton, knowing that he was in sole control of the power-plant, fought to retain possession of his faculties, while the hands of the clock told off the interminable minutes.

After an eternity of time an hour had passed, and Seaton attempted to cut down his power, only to find with horror that the long strain had so weakened him that he could not reverse the ratchet. He was still able, however, to give the lever the backward jerk which disconnected the wires completely—and the safety straps creaked with the sudden stress as, half the power instantly shut off, the suddenly released springs tried to hurl five bodies against the ceiling. After a few minutes DuQuesne revived and slowly cut off his power. To the dismay of both men they were again falling!

DuQuesne hurried to the lower window to make the observation, remarking:

"You're a better man than I am, Gunga Din."

"Only because you're so badly bunged up. One more notch would've got my goat," replied Seaton frankly as he made his way to Dorothy's side. He noticed as he reached her, that Crane had removed his helmet and was approaching the other girl. By the time DuQuesne had finished the observation, the other passengers had completely recovered, apparently none the worse for their experience.

* * * * *

"Did we gain anything?" asked Seaton eagerly.

"I make it two, four, thirteen. We've lost about two minutes of arc. How much power did we have on?"

"A little over half—thirty-two points out of sixty possible."

"We were still falling pretty fast. We'll have to put on everything we've got. Since neither of us can put it on we'll have to rig up an automatic feed. It'll take time, but it's the only way."

"The automatic control is already there," put in Crane, forestalling Seaton's explanation. "The only question is whether we will live through it—and that is not really a question, since certain death is the only alternative. We must do it."

"We sure must," answered Seaton soberly.

Dorothy gravely nodded assent.

"What do you fellows think of a little plus pressure on the oxygen?" asked Seaton. "I think it would help a lot."

"I think it's a good idea," said DuQuesne, and Crane added:

"Four or five inches of water will be about all the pressure we can stand. Any more might burn our lungs too badly."

The pressure apparatus was quickly arranged and the motors filled to capacity with reserve bars—enough to last seventy-two hours—the scientists having decided that they must risk everything on one trial and put in enough, if possible, to pull them clear out of the influence of this center of attraction, as the time lost in slowing up to change bars might well mean the difference between success and failure. Where they might lie at the end of the wild dash for safety, how they were to retrace their way with their depleted supply of copper, what other dangers of dead star, planet, or sun lay in their path—all these were terrifying questions that had to be ignored.

* * * * *

DuQuesne was the only member of the party who actually felt any calmness, the quiet of the others expressing their courage in facing fear. Life seemed very sweet and desirable to them, the distant earth a very Paradise! Through Dorothy's mind flashed the visions she had built up during long sweet hours, visions of a long life with Seaton. As she breathed an inaudible prayer, she glanced up and saw Seaton standing beside her, gazing down upon her with his very soul in his eyes. Never would she forget the expression upon his face. Even in that crucial hour, his great love for her overshadowed every other feeling, and no thought of self was in his mind—his care was all for her. There was a long farewell caress. Both knew that it might be goodbye, but both were silent as the violet eyes and the gray looked into each other's depths and conveyed messages far beyond the power of words. Once more he adjusted her helmet and strapped her into place.

As Crane had in the meantime cared for the other girl, the men again took their places and Seaton started the motor which would automatically advance the speed levers, one notch every five seconds, until the full power of both motors was exerted. As the power was increased, he turned the valve as before, until the helmets were filled with pure oxygen under a pressure of five inches of water.

Margaret Spencer, weakened by her imprisonment, was the first to lose consciousness, and soon afterward Dorothy felt her senses leave her. A half-minute, in the course of which six mighty surges were felt, as more of the power of the doubled motor was released, and Crane had gone, calmly analyzing his sensations to the last. After a time DuQuesne also lapsed into unconsciousness, making no particular effort to avoid it, as he knew that the involuntary muscles would function quite as well without the direction of the will. Seaton, although he knew it was useless, fought to keep his senses as long as possible, counting the impulses he felt as the levers were advanced.

"Thirty-two." He felt exactly as he had before, when he had advanced the lever for the last time.

"Thirty-three." A giant hand shut off his breath completely, though he was fighting to his utmost for air. An intolerable weight rested upon his eyeballs, forcing them backward into his head. The universe whirled about him in dizzy circles—orange and black and green stars flashed before his bursting eyes.

"Thirty-four." The stars became more brilliant and of more variegated colors, and a giant pen dipped in fire was writing equations and mathematico-chemical symbols upon his quivering brain. He joined the circling universe, which he had hitherto kept away from him by main strength, and whirled about his own body, tracing a logarithmic spiral with infinite velocity—leaving his body an infinite distance behind.

"Thirty-five." The stars and the fiery pen exploded in a wild coruscation of searing, blinding light and he plunged from his spiral into a black abyss.

* * * * *

In spite of the terrific stress put upon the machine, every part functioned perfectly, and soon after Seaton had lost consciousness the vessel began to draw away from the sinister globe; slowly at first, faster and faster as more and more of the almost unlimited power of the mighty motor was released. Soon the levers were out to the last notch and the machine was exerting its maximum effort. One hour and an observer upon the Skylark would have seen that the apparent size of the massive unknown world was rapidly decreasing; twenty hours and it was so far away as to be invisible, though its effect was still great; forty hours and the effect was slight; sixty hours and the Skylark was out of range of the slightest measurable force of the monster it had left.

Hurtled onward by the inconceivable power of the unleashed copper demon in its center, the Skylark flew through the infinite reaches of interstellar space with an unthinkable, almost incalculable velocity—beside which the velocity of light was as that of a snail to that of a rifle bullet; a velocity augmented every second by a quantity almost double that of light itself.



CHAPTER XI

Through Space Into the Carboniferous

Seaton opened his eyes and gazed about him wonderingly. Only half conscious, bruised and sore in every part of his body, he could not at first realize what had happened. Instinctively drawing a deep breath, he coughed and choked as the undiluted oxygen filled his lungs, bringing with it a complete understanding of the situation. Knowing from the lack of any apparent motion that the power had been sufficient to pull the car away from that fatal globe, his first thought was for Dorothy, and he tore off his helmet and turned toward her. The force of even that slight movement, wafted him gently into the air where he hung suspended several minutes before his struggles enabled him to clutch a post and draw himself down to the floor. A quick glance around informed him that Dorothy, as well as the others, was still unconscious. Making his way rapidly to her, he placed her face downward upon the floor and began artificial respiration. Very soon he was rewarded by the coughing he had longed to hear. He tore off her helmet and clasped her to his breast in an agony of relief, while she sobbed convulsively upon his shoulder. The first ecstasy of their greeting over, Dorothy started guiltily.

"Oh, Dick!" she exclaimed. "How about Peggy? You must see how she is!"

"Never mind," answered Crane's voice cheerily. "She is coming to nicely."

Glancing around quickly, they saw that Crane had already revived the stranger, and that DuQuesne was not in sight. Dorothy blushed, the vivid wave of color rising to her glorious hair, and hastily disengaged her arms from around her lover's neck, drawing away from him. Seaton, also blushing, dropped his arms, and Dorothy floated away from him, frantically clutching at a brace just beyond reach.

"Pull me down, Dick!" she called, laughing gaily.

Seaton, seizing her instinctively, neglected his own anchorage and they hung in the air together, while Crane and Margaret, each holding a strap, laughed with unrestrained merriment.

"Tweet, tweet—I'm a canary!" chuckled Seaton. "Throw us a rope!"

"A Dicky-bird, you mean," interposed Dorothy.

"I knew that you were a sleight-of-hand expert, Dick, but I did not know that levitation was one of your specialties," remarked Crane with mock gravity. "That is a peculiar pose you are holding now. What are you doing—sitting on an imaginary pedestal?"

"I'll be sitting on your neck if you don't get a wiggle on with that rope!" retorted Seaton, but before Crane had time to obey the command the floating couple had approached close enough to the ceiling so that Seaton, with a slight pressure of his hand against the leather, sent them floating back to the floor, within reach of one of the handrails.

Seaton made his way to the power-plant, lifted in one of the remaining bars, and applied a little power. The Skylark seemed to jump under them, then it seemed as though they were back on Earth—everything had its normal weight once more, as the amount of power applied was just enough to equal the acceleration of gravity. After this fact had been explained, Dorothy turned to Margaret.

"Now that we are able to act intelligently, the party should be introduced to each other. Peggy, this is Dr. Dick Seaton, and this is Mr. Martin Crane. Boys, this is Miss Margaret Spencer, a dear friend of mine. These are the boys I have told you so much about, Peggy. Dick knows all about atoms and things; he found out how to make the Skylark go. Martin, who is quite a wonderful inventor, made the engines and things for it."

"I may have heard of Mr. Crane," replied Margaret eagerly. "My father was an inventor, and I have heard him speak of a man named Crane who invented a lot of instruments for airplanes. He used to say that the Crane instruments revolutionized flying. I wonder if you are that Mr. Crane?"

"That is rather unjustifiably high praise, Miss Spencer," replied Crane, "but as I have been guilty of one or two things along that line, I may be the man he meant."

"Pardon me if I seem to change the subject," put in Seaton, "but where's DuQuesne?"

"We came to at the same time, and he went into the galley to fix up something to eat."

"Good for him!" exclaimed Dorothy. "I'm simply starved to death. I would have been demanding food long ago, but I have so many aches and pains that I didn't realize how hungry I was until you mentioned it. Come on, Peggy, I know where our room is. Let's go powder our noses while these bewhiskered gentlemen reap their beards. Did you bring along any of my clothes, Dick, or did you forget them in the excitement?"

"I didn't think anything about clothes, but Martin did. You'll find your whole wardrobe in your room. I'm with you, Dot, on that eating proposition—I'm hungry enough to eat the jamb off the door!"

* * * * *

After the girls had gone, Seaton and Crane went to their rooms, where they exercised vigorously to restore the circulation to their numbed bodies, shaved, bathed, and returned to the saloon feeling like new men. They found the girls already there, seated at one of the windows.

"Hail and greeting!" cried Dorothy at sight of them. "I hardly recognized you without your whiskers. Do hurry over here and look out this perfectly wonderful window. Did you ever in your born days see anything like this sight? Now that I'm not scared pea-green, I can enjoy it thoroughly!"

The two men joined the girls and peered out into space through the window, which was completely invisible, so clear was the glass. As the four heads bent, so close together, an awed silence fell upon the little group. For the blackness of the interstellar void was not the dark of an earthly night, but the absolute black of the absence of all light, beside which the black of platinum dust is pale and gray; and laid upon this velvet were the jewel stars. They were not the twinkling, scintillating beauties of the earthly sky, but minute points, so small as to seem dimensionless, yet of dazzling brilliance. Without the interference of the air, their rays met the eye steadily and much of the effect of comparative distance was lost. All seemed nearer and there was no hint of familiarity in their arrangement. Like gems thrown upon darkness they shone in multi-colored beauty upon the daring wanderers, who stood in their car as easily as though they were upon their parent Earth, and gazed upon a sight never before seen by eye of man nor pictured in his imaginings.

Through the daze of their wonder, a thought smote Seaton like a blow from a fist. His eyes leaped to the instrument board and he exclaimed:

"Look there, Mart! We're heading almost directly away from the Earth, and we must be making billions of miles per second. After we lost consciousness, the attraction of that big dud back there would swing us around, of course, but the bar should have stayed pointed somewhere near the Earth, as I left it. Do you suppose it could have shifted the gyroscopes?"

"It not only could have, it did," replied Crane, turning the bar until it again pointed parallel with the object-compass which bore upon the Earth. "Look at the board. The angle has been changed through nearly half a circumference. We couldn't carry gyroscopes heavy enough to counteract that force."

"But they were heavier there—Oh, sure, you're right. It's mass, not weight, that counts. But we sure are in one fine, large jam now. Instead of being half-way back to the Earth we're—where are we, anyway?"

They made a reading on an object-compass focused upon the Earth. Seaton's face lengthened as seconds passed. When it had come to rest, both men calculated the distance.

"What d'you make it, Mart? I'm afraid to tell you my result."

"Forty-six point twenty-seven light-centuries," replied Crane, calmly. "Right?"

"Right, and the time was 11:32 P. M. of Thursday, by the chronometer there. We'll time it again after a while and see how fast we're traveling. It's a good thing you built the ship's chronometers to stand any kind of stress. My watch is a total loss. Yours is, too?"

"All of our watches must be broken. We will have to repair them as soon as we get time."

"Well, let's eat next! No human being can stand my aching void much longer. How about you, Dot?"

"Yes, for Cat's sake, let's get busy!" she mimicked him gaily. "Doctor DuQuesne's had dinner ready for ages, and we're all dying by inches of hunger."

* * * * *

The wanderers, battered, bruised, and sore, seated themselves at a folding table, Seaton keeping a watchful eye upon the bar and upon the course, while enjoying Dorothy's presence to the full. Crane and Margaret talked easily, but at intervals. Save when directly addressed. DuQuesne maintained silence—not the silence of one who knows himself to be an intruder, but the silence of perfect self-sufficiency. The meal over, the girls washed the dishes and busied themselves in the galley. Seaton and Crane made another observation upon the Earth, requesting DuQuesne to stay out of the "engine room" as they called the partially-enclosed space surrounding the main instrument board, where were located the object-compasses and the mechanism controlling the attractor, about which DuQuesne knew nothing. As they rejoined DuQuesne in the main compartment, Seaton said:

"DuQuesne, we're nearly five thousand light-years away from the Earth, and are getting farther at the rate of about one light-year per minute."

"I suppose that it would be poor technique to ask how you know?"

"It would—very poor. Our figures are right. The difficulty is that we have only four bars left—enough to stop us and a little to spare, but not nearly enough to get back with, even if we could take a chance on drifting straight that far without being swung off—which, of course, is impossible."

"That means that we must land somewhere and dig some copper, then."

"Exactly.

"The first thing to do is to find a place to land."

Seaton picked out a distant star in their course and observed it through the spectroscope. Since it was found to contain copper in notable amounts, all agreed that its planets probably also contained copper.

"Don't know whether we can stop that soon or not," remarked Seaton as he set the levers, "but we may as well have something to shoot at. We'd better take our regular twelve-hour tricks, hadn't we, Mart? It's a wonder we got as far as this without striking another snag. I'll take the first trick at the board—beat it to bed."

"Not so fast, Dick," argued Crane, as Seaton turned toward the engine-room: "It's my turn."

"Flip a nickel," suggested Seaton. "Heads I get it."

Crane flipped a coin. Heads it was, and the worn-out party went to their rooms, all save Dorothy, who lingered after the others to bid her lover a more intimate good-night.

Seated beside him, his arm around her and her head upon his shoulder, Dorothy exclaimed:

"Oh, Dicky, Dicky, it is wonderful to be with you again! I've lived as many years in the last week as we have covered miles!"

Seaton kissed her with ardor, then turned her fair face up to his and gazed hungrily at every feature.

"It sure was awful until we found you, sweetheart girl. Those two days at Wilson's were the worst and longest I ever put in. I could have wrung Martin's cautious old neck!

"But isn't he a wiz at preparing for trouble? We sure owe him a lot, little dimpled lady."

Dorothy was silent for a moment, then a smile quirked at one corner of her mouth and a dimple appeared. Seaton promptly kissed it, whereupon it deepened audaciously.

"What are you thinking about—mischief?" he asked.

"Only of how Martin is going to be paid what we owe him," she answered teasingly. "Don't let the debt worry you any."

"Spill the news, Reddy," he commanded, as his arm tightened about her.

She stuck out a tiny tip of red tongue at him.

"Don't let Peggy find out he's a millionaire."

"Why not?" he asked wonderingly, then he saw her point and laughed:

"You little matchmaker!"

"I don't care, laugh if you want to. Martin's as nice a man as I know, and Peggy's a real darling. Don't you let slip a word about Martin's money, that's all!"

"She wouldn't think any less of him, would she?"

"Dick, sometimes you are absolutely dumb. It would spoil everything. If she knew he was a millionaire she would be scared to death—not of him, of course, but because she would think that he would think that she was chasing him, and then of course he would think that she was, see? As it is, she acts perfectly natural, and so does he. Didn't you notice that while we were eating they talked together for at least fifteen minutes about her father's invention and the way they stole the plans and one thing and another? I don't believe he has talked that much to any girl except me the last five years—and he wouldn't talk to me until he knew that I couldn't see any man except you. Much as we like Martin, we've got to admit that about him. He's been chased so much that he's wild. If any other girl he knows had talked to him that long, he would have been off to the North Pole or somewhere the next morning, and the best part of it is that he didn't think anything of it."

* * * * *

"You think she is domesticating the wild man?"

"Now, Dick, don't be foolish. You know what I mean. Martin is a perfect dear, but if she knew that he is the M. Reynolds Crane, everything would be ruined. You know yourself how horribly hard it is to get through his shell to the real Martin underneath. He is lonely and miserable inside, I know, and the right kind of girl, one that would treat him right, would make life Heaven for him, and herself too."

"Yes, and the wrong kind would make it...."

"She would," interrupted Dorothy hastily, "but Peggy's the right kind. Wouldn't it be fine to have Martin and Peggy as happy, almost, as you and I are?"

"All right, girlie, I'm with you," he answered, embracing her as though he intended never to let her go, "but you'd better go get some sleep—you're all in."

Considerably later, when Dorothy had finally gone, Seaton settled himself for the long vigil. Promptly at the end of the twelve hours Crane appeared, alert of eye and of bearing.

"You look fresh as a daisy, Mart. Feeling fit?"

"Fit as the proverbial fiddle. I could not have slept any better or longer if I had had a week off. Seven hours and a half is a luxury, you know."

"All wrong, old top. I need eight every night, and I'm going to take about ten this time."

"Go to it, twelve if you like. You have earned it."

Seaton stumbled to his room and slept as though in a trance for ten hours. Rising, he took his regular morning exercises and went into the saloon. All save Martin were there, but he had eyes only for his sweetheart, who was radiantly beautiful in a dress of deep bronze-brown.

"Good morning, Dick," she hailed him joyously. "You woke up just in time—we are all starving again, and were just going to eat without you!"

"Good morning, everybody. I would like to eat with you, Dottie, but I've got to relieve Martin. How'd it be for you to bring breakfast into the engine room and cheer my solitude, and let Crane eat with the others?"

"Fine—that's once you had a good idea, if you never have another!"

After the meal DuQuesne, who abhorred idleness with all his vigorous nature, took the watches of the party and went upstairs to the "shop," which was a completely-equipped mechanical laboratory, to repair them. Seaton stayed at the board, where Dorothy joined him as a matter of course. Crane and Margaret sat down at one of the windows.

She told him her story, frankly and fully, shuddering with horror as she recalled the awful, helpless fall, during which Perkins had met his end.

"Dick and I have a heavy score to settle with that Steel crowd and with DuQuesne," Crane said slowly. "We have no evidence that will hold in law, but some day DuQuesne will over-reach himself. We could convict him of abduction now, but the penalty for that is too mild for what he has done. Perkins' death was not murder, then?"

"Oh, no, it was purely self-defense. Perkins would have killed him if he could. And he really deserved it—Perkins was a perfect fiend. The Doctor, as they call him, is no better, although entirely different. He is so utterly heartless and ruthless, so cold and scientific. Do you know him very well?"

"We know all that about him, and more. And yet Dorothy said he saved her life?"

"He did, from Perkins, but I still think it was because he didn't want Perkins meddling in his affairs. He seems to me to be the very incarnation of a fixed purpose—to advance himself in the world."

"That expresses my thoughts exactly. But he slips occasionally, as in this instance, and he will again. He will have to walk very carefully while he is with us. Nothing would please Dick better than an excuse for killing him, and I must admit that I feel very much the same way."

"Yes, all of us do, and the way he acts proves what a machine he is. He knows just exactly how far to go, and never goes beyond it."

They felt the Skylark lurch slightly.

"Oh, Mart!" called Seaton. "Going to pass that star we were headed for—too fast to stop. I'm giving it a wide berth and picking out another one. There's a big planet a few million miles off in line with the main door, and another one almost dead ahead—that is, straight down. We sure are traveling. Look at that sun flit by!"

* * * * *

They saw the two planets, one like a small moon, the other like a large star, and saw the strange sun increase rapidly in size as the Skylark flew on at such a pace that any earthly distance would have been covered as soon as it was begun. So appalling was their velocity that their ship was bathed in the light of that sun for only a short time, then was again surrounded by the indescribable darkness. Their seventy-two-hour flight without a pilot had seemed a miracle, now it seemed entirely possible that they might fly in a straight line for weeks without encountering any obstacle, so vast was the emptiness in comparison with the points of light that punctuated it. Now and then they passed so close to a star that it apparently moved rapidly, but for the most part the silent sentinels stood, like distant mountain peaks to the travelers in an express train, in the same position for many minutes.

Awed by the immensity of the universe, the two at the window were silent, not with the silence of embarrassment, but with that of two friends in the presence of something beyond the reach of words. As they stared out into the infinity each felt as never before the pitiful smallness of even our whole solar system and the utter insignificance of human beings and their works. Silently their minds reached out to each other in mutual understanding.

Unconsciously Margaret half shuddered and moved closer to her companion, the movement attracting his attention but not her own. A tender expression came into Crane's steady blue eyes as he looked down at the beautiful young woman by his side. For beautiful she undoubtedly was. Untroubled rest and plentiful food had erased the marks of her imprisonment; Dorothy's deep, manifestly unassumed faith in the ability of Seaton and Crane to bring them safely back to Earth had quieted her fears; and a complete costume of Dorothy's simple but well-cut clothes, which fitted her perfectly, and in which she looked her best and knew it, had completely restored her self-possession. He quickly glanced away and again gazed at the stars, but now, in addition to the wonders of space, he saw masses of wavy black hair, high-piled upon a queenly head; deep down brown eyes half veiled by long, black lashes; sweet, sensitive lips; a firmly rounded but dimpled chin; and a perfectly-formed young body.

After a time she drew a deep, tremulous breath. As he turned, her eyes met his. In their shadowy depths, still troubled by the mystery of the unknowable, he read her very soul—the soul of a real woman.

"I had hoped," said Margaret slowly, "to take a long flight above the clouds, but anything like this never entered my mind. How unbelievably great it is! So much vaster than any perception we could get upon earth! It seems strange that we were ever awed by the sea or the mountains ... and yet...."

She paused, with her lip caught under two white teeth, then went on hesitatingly:

"Doesn't it seem to you, Mr. Crane, that there is something in man as great as all this? Otherwise, Dorothy and I could not be sailing here in a wonder like the Lark, which you and Dick Seaton have made."

* * * * *

Since from the first, Dorothy had timed her waking hours with those of Seaton—waiting upon him, preparing his meals, and lightening the long hours of his vigils at the board—Margaret took it upon herself to do the same thing for Crane. But often they assembled in the engine-room, and there was much fun and laughter, as well as serious talk, among the four. Margaret was quickly accepted as a friend, and proved a delightful companion. Her wavy, jet-black hair, the only color in the world that could hold its own with Dorothy's auburn glory, framed features self-reliant and strong, yet of womanly softness; and in this genial atmosphere her quick tongue had a delicate wit and a facility of expression that delighted all three. Dorothy, after the manner of Southern women, became the hostess of this odd "party," as she styled it, and unconsciously adopted the attitude of a lady in her own home.

Early in their flight, Crane suggested that they should take notes upon the systems of stars through which were passing.

"I know very little of astronomy," he said to Seaton, "but with our telescope, spectroscope, and other instruments, we should be able to take some data that will be of interest to astronomers. Possibly Miss Spencer would be willing to help us?"

"Sure," Seaton returned readily. "We'd be idiots to let a chance like this slide. Go to it!"

Margaret was delighted at the opportunity to help.

"Taking notes is the best thing I do!" she cried, and called for a pad and pencil.

Stationed at the window, they fell to work in earnest. For several hours Crane took observations, calculated distances, and dictated notes to Margaret.

"The stars are wonderfully different!" she exclaimed to him once. "That planet, I'm sure, has strange and lovely life upon it. See how its color differs from most of the others we have seen so near? It is rosy and soft like a home fire. I'm sure its people are happy."

They fell into a long discussion, laughing a little at their fancies. Were these multitudes of worlds peopled as the Earth? Could it be that only upon Earth had occurred the right combination for the generation of life, so that the rest of the Universe was unpeopled?

"It is unthinkable that they are all uninhabited," mused Crane. "There must be life. The beings may not exist in any form with which we are familiar—they may well be fulfilling some purpose in ways so different from ours that we should be unable to understand them at all."

Margaret's eyes widened in startled apprehension, but in a moment she shook herself and laughed.

"But there's no reason to suppose they would be awful," she remarked, and turned with renewed interest to the window.

Thus days went by and the Skylark passed one solar system after another, with a velocity so great that it was impossible to land upon any planet. Margaret's association with Crane, begun as a duty, soon became an intense pleasure for them both. Taking notes or seated at the board in companionable conversation or sympathetic silence, they compressed into a few days more real companionship than is ordinarily enjoyed in months. Oftener and oftener, as time went on, Crane found the vision of his dream home floating in his mind as he steered the Skylark in her meteoric flight or as he strapped himself into his narrow bed. Now, however, the central figure of the vision, instead of being an indistinct blur, was clear and sharply defined. And for her part, more and more was Margaret drawn to the quiet and unassuming, but utterly dependable and steadfast young inventor, with his wide knowledge and his keen, incisive mind.

* * * * *

Sometimes, when far from any star, the pilot would desert his post and join the others at meals. Upon one such occasion Seaton asked:

"How's the book on astronomy, oh, learned ones?"

"It will be as interesting as Egyptian hieroglyphics," Margaret replied, as she opened her notebook and showed him pages of figures and symbols.

"May I see it, Miss Spencer?" asked DuQuesne from across the small table, extending his hand.

She looked at him, hot hostility in her brown eyes, and he dropped his hand.

"I beg your pardon," he said, with amused irony.

After the meal Seaton and Crane held a short consultation, and the former called to the girls, asking them to join in the "council of war." There was a moment's silence before Crane said diffidently:

"We have been talking about DuQuesne, Miss Spencer, trying to decide a very important problem."

Seaton smiled in spite of himself as the color again deepened in Margaret's face, and Dorothy laughed outright.

"Talk about a red-headed temper! Your hair must be dyed, Peggy!"

"I know I acted like a naughty child," Margaret said ruefully, "but he makes me perfectly furious and scares me at the same time. A few more remarks like that 'I beg your pardon' of his and I wouldn't have a thought left in my head!"

Seaton, who had opened his mouth, shut it again ludicrously, without saying a word, and Margaret gave him a startled glance.

"Now I have said it!" she exclaimed. "I'm not afraid of him, boys, really. What do you want me to do?"

Seaton plunged in.

"What we were trying to get up nerve enough to say is that he'd be a good man on the astronomy job," and Crane added quickly:

"He undoubtedly knows more about it than I do, and it would be a pity to lose the chance of using him. Besides, Dick and I think it rather dangerous to leave him so much time to himself, in which to work up a plan against us."

"He's cooking one right now, I'll bet a hat," Seaton put in, and Crane added:

"If you are sure that you have no objections, Miss Spencer, we might go below, where we can have it dark, and all three of us see what we can make of the stargazing. We are really losing an unusual opportunity."

Margaret hid gallantly any reluctance she might have felt.

"I wouldn't deserve to be here if I can't work with the Doctor and hate him at the same time."

"Good for you, Peg, you're a regular fellow!" Seaton exclaimed. "You're a trump!"

* * * * *

Finally, the enormous velocity of the cruiser was sufficiently reduced to effect a landing, a copper-bearing sun was located, and a course was laid toward its nearest planet.

As the vessel approached its goal a deep undercurrent of excitement kept all the passengers feverishly occupied. They watched the distant globe grow larger, glowing through its atmosphere more and more clearly as a great disk of white light, its outline softened by the air about it. Two satellites were close beside it. Its sun, a great, blazing orb, a little nearer than the planet, looked so great and so hot that Margaret became uneasy.

"Isn't it dangerous to get so close, Dick? We might burn up, mightn't we?"

"Not without an atmosphere," he laughed.

"Oh," murmured the girl apologetically, "I might have known that."

Dropping rapidly into the atmosphere of the planet, they measured its density and analyzed it in apparatus installed for that purpose, finding that its composition was very similar to the Earth's air and that its pressure was not enough greater to be uncomfortable. When within one thousand feet of the surface, Seaton weighed a five-pound weight upon a spring-balance, finding that it weighed five and a half pounds, thus ascertaining that the planet was either somewhat larger than the Earth or more dense. The ground was almost hidden by a rank growth of vegetation, but here and there appeared glade-like openings.

Seaton glanced at the faces about him. Tense interest marked them all. Dorothy's cheeks were flushed, her eyes shone. She looked at him with awe and pride.

"A strange world, Dorothy," he said gravely. "You are not afraid?"

"Not with you," she answered. "I am only thrilled with wonder."

"Columbus at San Salvador," said Margaret, her dark eyes paying their tribute of admiration.

A dark flush mounted swiftly into Seaton's brown face and he sought to throw most of the burden upon Crane, but catching upon his face also a look of praise, almost of tenderness, he quickly turned to the controls.

"Man the boats!" he ordered an imaginary crew, and the Skylark descended rapidly.

Landing upon one of the open spaces, they found the ground solid and stepped out. What had appeared to be a glade was in reality a rock, or rather, a ledge of apparently solid metal, with scarcely a loose fragment to be seen. At one end of the ledge rose a giant tree wonderfully symmetrical, but of a peculiar form. Its branches were longer at the top than at the bottom, and it possessed broad, dark-green leaves, long thorns, and odd, flexible, shoot-like tendrils. It stood as an outpost of the dense vegetation beyond. Totally unlike the forests of Earth were those fern-like trees, towering two hundred feet into the air. They were of an intensely vivid green and stood motionless in the still, hot air of noonday. Not a sign of animal life was to be seen; the whole landscape seemed asleep.

The five strangers stood near their vessel, conversing in low tones and enjoying the sensation of solid ground beneath their feet. After a few minutes DuQuesne remarked:

"This is undoubtedly a newer planet than ours. I should say that it was in the Carboniferous age. Aren't those trees like those in the coal-measures, Seaton?"

"True as time, Blackie—there probably won't be a human race here for ages, unless we bring out some colonists."

Seaton kicked at one of the loose lumps of metal questioningly with his heavy shoe, finding that it was as immovable as though it were part of the ledge. Bending over, he found that it required all his great strength to lift it and he stared at it with an expression of surprise, which turned to amazement as he peered closer.

"DuQuesne! Look at this!"

* * * * *

DuQuesne studied the metal, and was shaken out of his habitual taciturnity.

"Platinum, by all the little gods!"

"We'll grab some of this while the grabbing's good," announced Seaton, and the few visible lumps were rolled into the car. "If we had a pickaxe we could chop some more off one of those sharp ledges down there."

"There's an axe in the shop," replied DuQuesne. "I'll go get it. Go ahead, I'll soon be with you."

"Keep close together," warned Crane as the four moved slowly down the slope. "This is none too safe, Dick."

"No, it isn't, Mart. But we've got to see whether we can't find some copper, and I would like to get some more of this stuff, too. I don't think it's platinum, I believe that it's X."

As they reached the broken projections, Margaret glanced back over her shoulder and screamed. The others saw that her face was white and her eyes wide with horror, and Seaton instinctively drew his pistol as he whirled about, only to check his finger on the trigger and lower his hand.

"Nothing but X-plosive bullets," he growled in disgust, and in helpless silence the four watched an unspeakably hideous monster slowly appear from behind the Skylark. Its four huge, squat legs supported a body at least a hundred feet long, pursy and ungainly; at the extremity of a long and sinuous neck a comparatively small head seemed composed entirely of a cavernous mouth armed with row upon row of carnivorous teeth. Dorothy gasped with terror and both girls shrank closer to the two men, who maintained a baffled silence as the huge beast passed his revolting head along the hull of the vessel.

"I dare not shoot, Martin," Seaton whispered, "it would wreck the bus. Have you got any solid bullets?"

"No. We must hide behind these small ledges until it goes away," answered Crane, his eyes upon Margaret's colorless face. "You two hide behind that one, we will take this one."
