At times he lay staring at the starry vault of the heavens with a vague longing within him to put the thing to the test. And always there was one star which seemed to call him, to beckon to him, to draw his spirit toward it as a magnet may draw a fleck of iron. That was the Dog Star, Sirius, known to astronomers as the sun of another planetary system like our own.

Meantime his studies went on. He learned that matter is the reflex of spirit; that no blade of gra.s.s, no chemical atom exists save as the envelope of an essence which cannot and does not die. He came to see that nature is no more than a realm of force, comprising light, heat, magnetism, chemical affinity, aura, essence, and all the imponderables which go to produce the various forms of motion as expressions of the ocean of force, so that motion comes to be no more than force refracted through the various forms of existence, from the lowest to the highest, as a ray of light is split into the seven primary colors by a prism, each being different in itself, yet each but an integral part of the original ray.

He came to comprehend that all stages of existence are but stages and nothing more, and that mind, spirit, is the highest form of life force--the true essence--manifesting through material means, yet independent of them in itself. So only, he argued, was life after death a possible thing. And so, he reasoned further, could the mystery be solved, there was no real reason why the spirit could not be set free to roam and return to the body at will. If that were true, it seemed to him that the spirit could return from such excursions, bringing with it a conscious recollection of the place where it had been.

Then once more he was called home by a thing which seems like no more than a further step in the course of what mortals call fate. His father's brother died. He was a bachelor. He left Croft sufficient wealth to provide for his every need. Croft decided to pursue his studies at home. He had gained all India could give him. Indeed, he had rather startled even Gatua Kahaun by some of the theories he had deduced.

He began work at once. He stocked the library where I had found him the night before, with everything on the subject he could find. And the more he studied, the more firmly did he become convinced that ordinary astral projection was but the first step in developing the spirit's power--that it was akin to the first step of an infant learning to walk, and that, if confidence were forthcoming, if the will to dare the experiment were sufficiently strong--then he could accomplish the thing of which he dreamed.

He began to experiment, sending his astral consciousness here and there. He centered on that one phase of his knowledge alone. He roamed the earth at will. He perfected his ability to bring back from such excursions a vivid recollection of all he had seen. So at last he was ready for the great experiment. Yet in the end he made it on impulse rather than at any pre-selected time.

He sat one evening on his porch. Over the eastern mountains which hem in the valley the full moon was rising in a blaze of mellow glory. Its rays caught the sleeping surface of a lake which lies near our little city, touching each rippling wavelet until they seemed made of molten silver. The lights of the town itself were like fireflies twinkling amid the trees. The mountains hazed somewhat in a silvery mist, compounded of the moonrays and distance, seemed to him no more than the figments of a fairy tale or a dream.

Everything was quiet. Mrs. Goss, now a widow, had gone to bed, and Croft had simply been enjoying the soft air and a cigar. Suddenly, as the moon appeared to leap free of the mountains, it suggested a thought of a spirit set free and rising above the material sh.e.l.l of existence to his mind.

He sat watching the golden wheel radiant with reflected light, and after a time he asked himself why he should not try the great adventure without a longer delay. He was the last of his race. No one depended upon him. Should he fail, they would merely find his body in the chair. Should he succeed, he would have won his ambition and placed himself in a position to learn of things which had heretofore baffled man.

He decided to try it there and then. Knocking the ash from his cigar, he took one last, long, possibly farewell whiff, and laid it down on the broad arm of his chair. Then summoning all the potent power of his will, he fixed his whole mind upon his purpose and sank into cataleptic sleep.

The moon is dead. In so much science is right. It is lifeless, without moisture, without an atmosphere. Croft won his great experiment, or its first step at least. His body sank to sleep, but his ego leaped into a fuller, wider life.

There was a sensation of airy lightness, as though his sublimated consciousness had dropped material weight. His body sat beneath him in the chair. He could see it. He could see the city and the lake and the mountains and the yellow disk of the moon. He knew he was rising toward the latter swiftly. Then--s.p.a.ce was annihilated in an instant, and he seemed to himself to be standing on the topmost edge of a mighty crater in the full, un.o.bstructed glare of a blinding light.

He sensed that was the sun, which hung like a ball of fire halfway up from the horizon, flinging its rays in a dazzling brilliance against the dead satellite's surface, unprotected by an atmospheric screen.

His first sensation was an amazing realization of his own success.

Then he gazed about.

To one side was the vast ring of the crater itself, a well of unutterable darkness and unplumbed depth, as yet not opened up to the burning light of the sun. To the other was the downward sweep of the crater's flank, dun, dead, wrinkled, seamed and seared by the stabbing rays which bathed it in pitiless light. And beyond the foot of the crater was a vast irregular plain, lower in the center as though eons past it might have been the bed of some vanished sea. About the plain were the crests of barren mountains, crags, pinnacles, misshapen and weird beyond thought.

Yes, the moon is dead--now. But--there was life upon it once. Croft willed himself down from the lip of the crater to the plain. He moved about it. Indeed it had been a sea. There in the airless blaze, still etched in the lifeless formations, he found an ancient water-line, the mark of the fingers of vanished waters--like a mockery of what had been. And skirting the outline of that long-lost sea, he came to the ruin of a city which had stood upon the sh.o.r.es a myriad years ago. It stood there still--a thing of paved streets, and dead walls, safe in that moistureless world from decay.

Through those dead streets and houses, some of them thrown down by terrific earthquakes which he judged had accompanied the final cooling stages and death of the moon, Croft took his way, pausing now and then to examine some ancient inscriptions cut into the blocks of stone from which the buildings had been reared. In a way they impressed him as similar in many respects to the Asiatic structures of to-day, most of them being windowless on the first story, but built about an inner court, gardens of beauty in the time when the moon supported life.

So far as he could judge from the buildings themselves and frescoes on the walls, done in pigments which still prevailed, the lunarians had been a tiny people, probably not above an average of four feet in height, but extremely intelligent past any doubt, as shown by the remains of their homes. They had possessed rather large heads in proportion to their slender bodies, as the paintings done on the inside walls led Croft to believe.

From the same source he became convinced that their social life had been highly developed, and that they had been well versed in the arts of manufacture and commerce, and had at the time when lunar seas persisted maintained a merchant marine.

Through the hours of the lunar day he explored. Not, in fact, until the sun was dropping swiftly below the rim of the mountains beyond the old sea-bed, did he desist. Then lifting his eyes he beheld a luminous crescent, many times larger than the moon appears to us, emitting a soft, green light. He stood and gazed upon it for some moments before he realized fully that he looked upon a sunrise on the earth--that the monster crescent was the earth indeed as seen from her satellite.

Then as realization came upon him he remembered his body--left on the porch of his home in the chair. Suddenly he felt a longing to return, to forsake the forsaken relics of a life which had pa.s.sed and go back to the full, pulsing tide of life which still flowed on.

Here, then, he was faced by the second step of his experiment. He had consciously reached the moon. Could he return again to the earth? If so, he had proved his theory beyond any further doubt. Fastening his full power upon the endeavor, he willed himself back, and--

He opened his eyes--his physical eyes--and gazed into the early sun of a new day rising over the mountains and turning the world to emerald and gold.

The sound of a caught-in breath fell on his ears. He turned his glance. Mrs. Goss stood beside him.

"Laws, sir, but you was sound asleep!" she exclaimed. "I come to call you to breakfast an' you wasn't in your room, an' when I found you you was sleepin' like th' dead. You must have got up awful early, Mr.

Jason."

"I was here before you were moving," Croft said as he rose. He smiled as he spoke. Indeed, he wanted to laugh, to shout. He had done what no mortal had ever accomplished before. The wonders of the universe were his to explore at will. Yet even so he did not dream of what the future held.

3. BEYOND THE MOON

And now the Dog Star called. Croft had proved his ability to project his conscious self beyond earth's attraction and return. And, having proved that, the old lure of the star he had watched when a student in the Indian mountains came back with a double strength. No longer was it an occasional prompting. Rather it was a never-ceasing urge which nagged him night and day.

He yielded at last. But remembering his return from his first experiment, he arranged for the next with due care. In order that Mrs.

Goss might not become alarmed by seeing his body entranced, he arranged for her to take a holiday with a married daughter in another part of the state, telling her simply that he himself expected to be absent from his home for an indefinite time and would summon her upon his return.

He knew the woman well enough to be sure she would spread the word of his coming absence, and so felt a.s.sured that his body would remain undisturbed during the period of his venture into universal s.p.a.ce.

Having seen the old woman depart, he entered the library, drew down all the blinds, and stretched himself on the couch. Fixing his mind on Sirius to the exclusion of everything else, he threw off the bonds of the flesh.

Yet here, as it chanced, even Croft made a well-nigh fatal mistake. It was toward Sirius he had willed himself in his thoughts, and Sirius is a sun. As a result, he realized none too soon that he was floating in the actual nebula surrounding the flaming orb itself.

Directly beneath him, as it appeared, the Dog Star rolled, a ma.s.s of electric fire. Mountains of flame ran darting off into s.p.a.ce in all directions. Between them the whole surface of the sun boiled and bubbled and seethed like a world-wide cauldron. Not for a moment was there any rest upon that surface toward which he was sinking with incredible speed. Every atom of the monster sun was in motion, ever shifting, ever changing yet always the same. It quivered and billowed and shook. Flames of every conceivable color radiated from it in waves of awful heat. Vast explosions recurred again and again on the ever heaving surface. What seemed unthinkable hurricanes rushed into the voids created by the exploding gases.

In this maelstrom of t.i.tanic forces Croft found himself caught. Not even the wonderful force his spirit had attained could overcome the sun's power of repulsion. His progress stayed, he hung above the molten globe beneath him, imprisoned, unable to extricate himself from his position, buffeted, swirled about and swayed by the irresistible forces which warred around him in a never-ceasing tumult such as he had never conceived.

Something like a vague question as to his fate rather than any fear a.s.sailed him, something like a blind wonder. The force which held him was one beyond his experience or knowledge. He knew that a true spirit, a pure ego, could not wholly perish, yet now he asked himself what would be the effect of close proximity to such an enormous center of elemental activity upon an ego not wholly sublimated, such as his.

His will power actually faltered, staggered. For the time being he lost his ability to choose his course. He had willed himself here, and here he was, but he found himself unable to will himself back or anywhere else, in fact. The sensation crept through his soul that he was a plaything of fate, a mad ego which had ventured too far, dared too much, sought to learn those things possibly forbidden, hence caught in a net of universal law, woven about him by his own mad thirst for knowledge--a spirit doomed by its own daring to an eternity of something closely approaching the orthodox h.e.l.l.

Through eons of time, as it seemed to him, he hung above that blazing orb, surrounded by seething gases which dimmed but did not wholly obscure his vision. Then a change began taking place. A great spot of darkness appeared on the pulsing body of the sun. It widened swiftly.

About it the fiery elements of molten ma.s.s seemed to center their main endeavor. Vast streamers of flaming gas leaped and darted about its spreading center. It stretched and spread.

To Croft's fascinated vision it showed a mighty, funnel-like chasm, reaching down for thousands of miles into the very heart of their solar ma.s.s. And suddenly he knew that once more he was sinking, was being drawn down, down, to be engulfed in that terrible throat of the terrifying funnel, swept and sucked down like a bit of driftwood into the maw of a whirlpool, powerless to resist.

Down he sank, down, between walls of living fire which swirled about him with an inconceivable velocity of revolution. The vapors which closed about him seemed to stifle even his spirit senses. Down, down, how far he had no conception. He had lost all control, all conscious power to judge of time or distance. Yet he was able still to see. And so at last he sensed that the fiery walls were coming swiftly together.

For a wild instant he conceived himself engulfed. Then he knew that he was being thrown out and upward again with terrific force, literally crowded forth with the out-rushing gases between the collapsing walls, and hurled again into s.p.a.ce.

Darkness came down, a darkness so deep it seemed a thousand suns might not pierce it through with their rays. Sirius, the great sun, seemed blotted out. He was seized by a sense of falling through that Stygian shroud. In which direction he knew not, or why or how. He knew only that his ego over which he had lost control was swirling in vast spirals down and down through an endless void to an endless fate--that he who had come so confidently forth to explore the universal secrets had become a waif in the uncharted immensity of the eternal universe.

The sensation went on and on. So much he knew. Still he was conscious.

The thought came to him that this was his punishment for daring to know. Still conscious, he must be still bound by natural law. Had he broken that law and been cast into utter darkness, to remain forever conscious of his fate? Yet if so, where was he falling, where was he to wander, and for how long? His senses reeled.

By degrees, however, he fought back to some measure of control. His very necessity prompted the attempt. And by degrees there came to him a sense of not being any longer alone. In the almost palpable darkness it seemed that other shapes and forms, whose warp and woof was darkness also, floated and writhed about him as he fell.
