The view was, of course, superb, but while I was admiring it in all its wonderful extent and variety, Hall, who had immediately pulled out his binocular, was busy inspecting the Syx works, the top of whose great tufted smoke column was thousands of feet beneath our level. Jackson's Lake, Jenny's Lake, Leigh's Lake, and several lakelets glittered in the sunlight amid the pale grays and greens of Jackson's Hole, while many a bending reach of the Snake River shone amid the wastes of sage-brush and rock.

"There!" suddenly exclaimed Hall, "I thought I should find it."

"What?"

"Take a look through my glass at the roof of Syx's mill. Look just in the centre."

"Why, it's open in the middle!" I cried as soon as I had put the glass to my eyes. "There's a big circular hole in the centre of the roof,"

"Look inside! Look inside!" repeated Hall, impatiently.

"I see nothing there except something bright."

"Do you call it nothing because it is bright?"

"Well, no," I replied, laughing. "What I mean is that I see nothing that I can make anything of except a shining object, and all I can make of that is that it is bright."

"You've been in the Syx works many times, haven't you?"

"Yes."

"Did you ever see the opening in the roof?"

"Never."

"Did you ever hear of it?"

"Never."

"Then Dr. Syx doesn't show his visitors everything that is to be seen."

"Evidently not since, as we know, he concealed the double tunnel and the room under the furnace."

"Dr. Syx has concealed a bigger secret than that," Hall responded, "and the Grand Teton has helped me to a glimpse of it."

For several minutes my friend was absorbed in thought. Then he broke out:

"I tell you he's the most wonderful man in the world!"

"Who, Dr. Syx? Well, I've long thought that."

"Yes, but I mean in a different way from what you are thinking of. Do you remember my asking you once if you believed in alchemy?"

"I remember being greatly surprised by your question to that effect."

"Well, now," said Hall, rubbing his hands with a satisfied air, while his eyes glanced keen and bright with the reflection of some passing thought, "Max Syx is greater than any alchemist that ever lived. If those old fellows in the dark ages had accomplished everything they set out to do, they would have been of no more consequence in comparison with our black-browed friend down yonder than—than my head is of consequence in comparison with the moon."

"I fear you flatter the man in the moon," was my laughing reply.

"No, I don't," returned Hall, "and some day you'll admit it."

"Well, what about that something that shines down there? You seem to see more in it than I can."

But my companion had fallen into a reverie and didn't hear my question. He was gazing abstractedly at the faint image of the waning moon, now nearing the distant mountain-top over in Idaho. Presently his mind seemed to return to the old magnet, and he whirled about and glanced down at the Syx mill. The column of smoke was diminishing in volume, an indication that the engine was about to enjoy one of its periodical rests. The irregularity of these stoppages had always been a subject of remark among practical engineers. The hours of labor were exceedingly erratic, but the engine had never been known to work at night, except on one occasion, and then only for a few minutes, when it was suddenly stopped on account of a fire.

Just as Hall resumed his inspection two huge quarter spheres, which had been resting wide apart on the roof, moved towards one another until their arched sections met over the circular aperture which they covered like the dome of an observatory.

"I expected it," Hall remarked. "But come, it is mid-afternoon, and we shall need all of our time to get safely down before the light fades."

As I have already explained, it would not have been possible for us to return the way we came. We determined to descend the comparatively easy western slopes of the peak, and pass the night on that side of the mountain. Letting ourselves down with the rope into the hollow way that divides the summit of the Teton into two pinnacles, we had no difficulty in descending by the route followed by all previous climbers. The weather was fine, and, having found good shelter among the rocks, we passed the night in comfort. The next day we succeeded in swinging round upon the eastern flank of the Teton, below the more formidable cliffs, and, just at nightfall, we arrived at the station. As we passed the Syx mine the doctor himself confronted us. There was a very displeasing look on his dark countenance, and his sneer was strongly marked.

"So you have been on top of the Teton?" he said.

"Yes," replied Hall, very blandly, "and if you have a taste for that sort of thing I should advise you to go up. The view is immense, as fine as the best in the Alps."

"Pretty ingenious plan, that balloon of yours," continued the doctor, still looking black.

"Thank you," Hall replied, more suavely than ever. "I've been planning that a long time. You probably don't know that mountaineering used to be my chief amusement."

The doctor turned away without pursuing the conversation.

"I could kick myself," Hall muttered as soon as Dr. Syx was out of earshot. "If my absurd wish to outdo others had not blinded me, I should have known that he would see us going up this side of the peak, particularly with the balloon to give us away. However, what's done can't be undone. He may not really suspect the truth, and if he does he can't help himself, even though he is the richest man in the world."



XI

STRANGE FATE OF A KITE

"Are you ready for another tramp?" was Andrew Hall's greeting when we met early on the morning following our return from the peak.

"Certainly I am. What is your programme for to-day?"

"I wish to test the flying qualities of a kite which I have constructed since our return last night."

"You don't allow the calls of sleep to interfere very much with your activity."

"I haven't much time for sleep just now," replied Hall, without smiling. "The kite test will carry us up the flanks of the Teton, but I am not going to try for the top this time. If you will come along I'll ask you to help me by carrying and operating a light transit I shall carry another myself. I am desirous to get the elevation that the kite attains and certain other data that will be of use to me. We will make a detour towards the south, for I don't want old Syx's suspicions to be prodded any more."

"What interest can he have in your kite-flying?"

"The same interest that a burglar has in the rap of a policeman's night-stick."

"Then your experiment to-day has some connection with the solution of the great mystery?"

"My dear fellow," said Hall, laying his hand on my shoulder, "until I see the end of that mystery I shall think of nothing else."

In a few hours we were clambering over the broken rocks on the south-eastern flank of the Teton at an elevation of about three thousand feet above the level of Jackson's Hole. Finally Hall paused and began to put his kite together. It was a small box-shaped affair, very light in construction, with paper sides.

"In order to diminish the chances of Dr. Syx noticing what we are about," he said, as he worked away, "I have covered the kite with sky-blue paper. This, together with distance, will probably insure us against his notice."

In a few minutes the kite was ready. Having ascertained the direction of the wind with much attention, he stationed me with my transit on a commanding rock, and sought another post for himself at a distance of two hundred yards, which he carefully measured with a gold tape. My instructions were to keep the telescope on the kite as soon as it had attained a considerable height, and to note the angle of elevation and the horizontal angle with the base line joining our points of observation.

"Be particularly careful," was Hall's injunction, "and if anything happens to the kite by all means note the angles at that instant."

As soon as we had fixed our stations Hall began to pay out the string, and the kite rose very swiftly. As it sped away into the blue it was soon practically invisible to the naked eye, although the telescope of the transit enabled me to follow it with ease.

Glancing across now and then at my companion, I noticed that he was having considerable difficulty in, at the same time, managing the kite and manipulating his transit. But as the kite continued to rise and steadied in position his task became easier, until at length he ceased to remove his eye from the telescope while holding the string with outstretched hand.

"Don't lose sight of it now for an instant!" he shouted.

For at least half an hour he continued to manipulate the string, sending the kite now high towards the zenith with a sudden pull, and then letting it drift off. It seemed at last to become almost a fixed point. Very slowly the angles changed, when, suddenly, there was a flash, and to my amazement I saw the paper of the kite shrivel and disappear in a momentary flame, and then the bare sticks came tumbling out of the sky.

"Did you get the angles?" yelled Hall, excitedly.

"Yes; the telescope is yet pointed on the spot where the kite disappeared."

"Read them off," he called, "and then get your angle with the Syx works."

"All right," I replied, doing as he had requested, and noticing at the same time that he was in the act of putting his watch in his pocket. "Is there anything else?" I asked.

"No, that will do, thank you."

Hall came running over, his face beaming, and with the air of a man who has just hooked a particularly cunning old trout.

"Ah!" he exclaimed, "this has been a great success! I could almost dispense with the calculation, but it is best to be sure."

"What are you about, anyhow?" I asked, "and what was it that happened to the kite?"

"Don't interrupt me just now, please," was the only reply I received.

Thereupon my friend sat down on a rock, pulled out a pad of paper, noted the angles which I had read on the transit, and fell to figuring with feverish haste. In the course of his work he consulted a pocket almanac, then glanced up at the sky, muttered approvingly, and finally leaped to his feet with a half-suppressed "Hurrah!" If I had not known him so well I should have thought that he had gone daft.

"Will you kindly tell me," I asked, "how you managed to set the kite afire?"

Hall laughed heartily. "You though it was a trick, did you?" said he. "Well, it was no trick, but a very beautiful demonstration. You surely haven't forgotten the scarlet tanager that gave you such a surprise the day before yesterday."

"Do you mean" I exclaimed, startled at the suggestion, "that the fate of the bird had any connection with the accident to your kite?"

"Accident isn't precisely the right word," replied Hall. "The two things are as intimately related as own brothers. If you should care to hunt up the kite sticks, you would find that they, too, are now artemisium plated."

"This is getting too deep for me," was all that I could say.

"I am not absolutely confident that I have touched bottom myself," said Hall, "but I'm going to make another dive, and if I don't bring up treasures greater than Vanderdecken found at the bottom of the sea, then Dr. Syx is even a more wonderful human mystery than I have thought him to be."

"What do you propose to do next?"

"To shake the dust of the Grand Teton from my shoes and go to San Francisco, where I have an extensive laboratory."

"So you are going to try a little alchemy yourself, are you?"

"Perhaps; who knows? At any rate, my good friend, I am forever indebted to you for your assistance, and even more for your discretion, and if I succeed you shall be the first person in the world to hear the news."



XII

BETTER THAN ALCHEMY

I come now to a part of my narrative which would have been deemed altogether incredible in those closing years of the nineteenth century that witnessed the first steps towards the solution of the deepest mysteries of the ether, although men even then held in their hands, without knowing it, powers which, after they had been mastered and before use had made them familiar, seemed no less than godlike.

For six months after Hall's departure for San Francisco I heard nothing from him. Notwithstanding my intense desire to know what he was doing, I did not seek to disturb him in his retirement. In the meantime things ran on as usual in the world, only a ripple being caused by renewed discoveries of small nuggets of artemisium on the Tetons, a fact which recalled to my mind the remark of my friend when he dislodged a flake of the metal from a crevice during our ascent of the peak. At last one day I received this telegram at my office in New York:

"SAN FRANCISCO, May 16, 1940.

"Come at once. The mystery is solved.

"(Signed) HALL."

As soon as I could pack a grip I was flying westward one hundred miles an hour. On reaching San Francisco, which had made enormous strides since the opening of the twentieth century, owing to the extension of our Oriental possessions, and which already ranked with New York and Chicago among the financial capitals of the world, I hastened to Hall's laboratory. He was there expecting me, and, after a hearty greeting, during which his elation over his success was manifest, he said:

"I am compelled to ask you to make a little journey. I found it impossible to secure the necessary privacy here, and, before opening my experiments, I selected a site for a new laboratory in an unfrequented spot among the mountains this side of Lake Tahoe. You will be the first man, with the exception of my two devoted assistants, to see my apparatus, and you shall share the sensation of the critical experiment."

"Then you have not yet completed your solution of the secret?"

"Yes, I have; for I am as certain of the result as if I had seen it, but I thought you were entitled to be in with me at the death."

From the nearest railway station we took horses to the laboratory, which occupied a secluded but most beautiful site at an elevation of about six thousand feet above sea-level. With considerable surprise I noticed a building surmounted with a dome, recalling what we had seen from the Grand Teton on the roof of Dr. Syx's mill. Hall, observing my look, smiled significantly, but said nothing. The laboratory proper occupied a smaller building adjoining the domed structure. Hall led the way into an apartment having but a single door and illuminated by a skylight.

"This is my sanctum sanctorum," he said, "and you are the first outsider to enter it. Seat yourself comfortably while I proceed to unveil a little corner of the artemisium mystery."

Near one end of the room, which was about thirty feet in length, was a table, on which lay a glass tube about two inches in diameter and thirty inches long. In the farther end of the tube gleamed a lump of yellow metal, which I took to be gold. Hall and I were seated near another table about twenty-five feet distant from the tube, and on this table was an apparatus furnished with a concave mirror, whose optical axis was directed towards the tube. It occurred to me at once that this apparatus would be suitable for experimenting with electric waves. Wires ran from it to the floor, and in the cellar beneath was audible the beating of an engine. My companion made an adjustment or two, and then remarked:

"Now, keep your eyes on the lump of gold in the farther end of the tube yonder. The tube is exhausted of air, and I am about to concentrate upon the gold an intense electric influence, which will have the effect of making it a kind of kathode pole. I only use this term for the sake of illustration. You will recall that as long ago as the days of Crookes it was known that a kathode in an exhausted tube would project particles, or atoms, of its substance away in straight lines. Now watch!"

I fixed my attention upon the gold, and presently saw it enveloped in a most beautiful violet light. This grew more intense, until, at times, it was blinding, while, at the same moment, the interior of the tube seemed to have become charged with a luminous vapor of a delicate pinkish hue.

"Watch! Watch!" said Hall. "Look at the nearer end of the tube!"

"Why, it is becoming coated with gold!" I exclaimed.

He smiled, but made no reply. Still the strange process continued. The pink vapor became so dense that the lump of gold was no longer visible, although the eye of violet light glared piercingly through the colored fog. Every second the deposit of metal, shining like a mirror, increased, until suddenly there came a curious whistling sound. Hall, who had been adjusting the mirror, jerked away his hand and gave it a flip, as if hot water had spattered it, and then the light in the tube quickly died away, the vapor escaped, filling the room with a peculiar stimulating odor, and I perceived that the end of the glass tube had been melted through, and the molten gold was slowly dripping from it.

"I carried it a little too far," said Hall, ruefully rubbing the back of his hand, "and when the glass gave way under the atomic bombardment a few atoms of gold visited my bones. But there is no harm done. You observed that the instant the air reached the kathode, as I for convenience call the electrified mass of gold, the action ceased."

"But your anode, to continue your simile," I said, "is constantly exposed to the air."

"True," he replied, "but in the first place, of course, this is not really an anode, just as the other is not actually a kathode. As science advances we are compelled, for a time, to use old terms in a new sense until a fresh nomenclature can be invented. But we are now dealing with a form of electric action more subtile in its effects than any at present described in the text-books and the transactions of learned societies. I have not yet even attempted to work out the theory of it. I am only concerned with its facts."

"But wonderful as the exhibition you have given is, I do not see," I said, "how it concerns Dr. Syx and his artemisium."

"Listen," replied Hall, settling back in his chair after disconnecting his apparatus. "You no doubt have been told how one night the Syx engine was heard working for a few minutes, the first and only night work it was ever known to have done, and how, hardly had it started up when a fire broke out in the mill, and the engine was instantly stopped. Now there is a very remarkable story connected with that, and it will show you how I got my first clew to the mystery, although it was rather a mere suspicion than a clew, for at first I could make nothing out of it. The alleged fire occurred about a fortnight after our discovery of the double tunnel. My mind was then full of suspicions concerning Syx, because I thought that a man who would fool people with one hand was not likely to deal fairly with the other.

"It was a glorious night, with a full moon, whose face was so clear in the limpid air that, having found a snug place at the foot of a yellow-pine-tree, where the ground was carpeted with odoriferous needles, I lay on my back and renewed my early acquaintance with the romantically named mountains and 'seas' of the Lunar globe. With my binocular I could trace those long white streaks which radiate from the crater ring, called 'Tycho,' and run hundreds of miles in all directions over the moon. As I gazed at these singular objects I recalled the various theories which astronomers, puzzled by their enigmatical aspect, have offered to a more or less confiding public concerning them.

"In the midst of my meditation and moon gazing I was startled by hearing the engine in the Syx works suddenly begin to run. Immediately a queer light, shaped like the beam of a ship's searchlight, but reddish in color, rose high in the moonlit heavens above the mill. It did not last more than a minute or two, for almost instantly the engine was stopped, and with its stoppage the light faded and soon disappeared. The next day Dr. Syx gave it out that on starting up his engine in the night something had caught fire, which compelled him immediately to shut down again. The few who had seen the light, with the exception of your humble servant, accepted the doctor's explanation without a question. But I knew there had been no fire, and Syx's anxiety to spread the lie led me to believe that he had narrowly escaped giving away a vital secret. I said nothing about my suspicions, but upon inquiry I found out that an extra and pressing order for metal had arrived from the Austrian government the very day of the pretended fire, and I drew the inference that Syx, in his haste to fill the order—his supply having been drawn low—had started to work, contrary to his custom, at night, and had immediately found reason to repent his rashness. Of course, I connected the strange light with this sudden change of mind.

"My suspicion having been thus stimulated, and having been directed in a certain way, I began, from that moment to notice closely the hours during which the engine labored. At night it was always quiet, except on that one brief occasion. Sometimes it began early in the morning and stopped about noon. At other times the work was done entirely in the afternoon, beginning sometimes as late as three or four o'clock, and ceasing invariably at sundown. Then again it would start at sunrise and continue the whole day through.

"For a long time I was unable to account for these eccentricities, and the problem was not rendered much clearer, although a startling suggestiveness was added to it, when, at length, I noticed that the periods of activity of the engine had a definite relation to the age of the moon. Then I discovered, with the aid of an almanac, that I could predict the hours when the engine would be busy. At the time of new moon it worked all day; at full moon, it was idle; between full moon and last quarter, it labored in the forenoon, the length of its working hours increasing as the quarter was approached; between last quarter and new moon, the hours of work lengthened, until, as I have said, at new moon they lasted all day; between new moon and first quarter, work began later and later in the forenoon as the quarter was approached, and between first quarter and full moon the laboring hours rapidly shortened, being confined to the latter part of the afternoon, until at full moon complete silence reigned in the mill."

"Well! well!" I broke in, greatly astonished by Hall's singular recital, "you must have thought Dr. Syx was a cross between an alchemist and an astrologer."

"Note this," said Hall, disregarding my interruption, "the hours when the engine worked were invariably the hours during which the moon was above the horizon!"

"What did you infer from that?" "Of course, I inferred that the moon was directly concerned in the mystery; but how? That bothered me for a long time, but a little light broke into my mind when I picked up, on the mountain-side, a dead bird, whose scorched feathers were bronzed with artemisium, and sometime later another similar victim of a mysterious form of death. Then came the attack on the mine and its tragic finish. I have already told you what I observed on that occasion. But, instead of helping to clear up the mystery, it rather complicated it for a time. At length, however, I reasoned my way partly out of the difficulty. Certain things which I had noticed in the Syx mill convinced me that there was a part of the building whose existence no visitor suspected, and, putting one thing with another, I inferred that the roof must be open above that secret part of the structure, and that if I could get upon a sufficiently elevated place I could see something of what was hidden there.

"At this point in the investigation I proposed to you the trip to the top of the Teton, the result of which you remember. I had calculated the angles with great care, and I felt certain that from the apex of the mountain I should be able to get a view into the concealed chamber, and into just that side of it which I wished particularly to inspect. You remember that I called your attention to a shining object underneath the circular opening in the roof. You could not make out what it was, but I saw enough to convince me that it was a gigantic parabolic mirror. I'll show you a smaller one of the same kind presently.

"Now, at last, I began to perceive the real truth, but it was so wildly incredible, so infinitely remote from all human experience, that I hardly ventured to formulate it, even in my own secret mind. But I was bound to see the thing through to the end. It occurred to me that I could prove the accuracy of my theory with the aid of a kite. You were kind enough to lend your assistance in that experiment, and it gave me irrefragable evidence of the existence of a shaft of flying atoms extending in a direct line between Dr. Syx's pretended mine and the moon!"

"Hall!" I exclaimed, "you are mad!" My friend smiled good-naturedly, and went on with his story.

"The instant the kite shrivelled and disappeared I understood why the works were idle when the moon was not above the horizon, why birds flying across that fatal beam fell dead upon the rocks, and whence the terrible master of that mysterious mill derived the power of destruction that could wither an army as the Assyrian host in Byron's poem

"Melted like snow in the glance of the Lord."

"But how did Dr. Syx turn the flying atoms against his enemies?" I asked.

"In a very simple manner. He had a mirror mounted so that it could be turned in any direction, and would shunt the stream of metallic atoms, heated by their friction with the air, towards any desired point. When the attack came he raised this machine above the level of the roof and swept the mob to a lustrous, if expensive, death."

"And the light at night—"

"Was the shining of the heated atoms, not luminous enough to be visible in broad day, for which reason the engine never worked at night, and the stream of volatilized artemisium was never set flowing at full moon, when the lunar globe is above the horizon only during the hours of darkness."

"I see," I said, "whence came the nuggets on the mountain. Some of the atoms, owing to the resistance of the air, fell short and settled in the form of impalpable dust until the winds and rains collected and compacted them in the cracks and crevices of the rocks."

"That was it, of course."

"And now," I added, my amazement at the success of Hall's experiments and the accuracy of his deductions increasing every moment, "do you say that you have also discovered the means employed by Dr. Syx to obtain artemisium from the moon?"

"Not only that," replied my friend, "but within the next few minutes I shall have the pleasure of presenting to you a button of moon metal, fresh from the veins of Artemis herself."



XIII

THE LOOTING OF THE MOON

I shall spare the reader a recital of the tireless efforts, continuing through many almost sleepless weeks, whereby Andrew Hall obtained his clew to Dr. Syx's method. It was manifest from the beginning that the agent concerned must be some form of etheric, or so-called electric, energy; but how to set it in operation was the problem. Finally he hit upon the apparatus for his initial experiments which I have already described.

"Recurring to what had been done more than half a century ago by Hertz, when he concentrated electric waves upon a focal point by means of a concave mirror," said Hall, "I saw that the key I wanted lay in an extension of these experiments. At last I found that I could transform the energy of an engine into undulations of the ether, which, when they had been concentrated upon a metallic object, like a chunk of gold, imparted to it an intense charge of an apparently electric nature. Upon thus charging a metallic body enclosed in a vacuum, I observed that the energy imparted to it possessed the remarkable power of disrupting its atoms and projecting them off in straight lines, very much as occurs with a kathode in a Crookes's tube. But—and this was of supreme importance—I found that the line of projection was directly towards the apparatus from which the impulse producing the charge had come. In other words, I could produce two poles between which a marvellous interaction occurred. My transformer, with its concentrating mirror, acted as one pole, from which energy was transferred to the other pole, and that other pole immediately flung off atoms of its own substance in the direction of the transformer. But these atoms were stopped by the glass wall of the vacuum tube; and when I tried the experiment with the metal removed from the vacuum, and surrounded with air, it failed utterly.

"This at first completely discouraged me, until I suddenly remembered that the moon is in a vacuum, the great vacuum of interplanetary space, and that it possesses no perceptible atmosphere of its own. At this a great light broke around me, and I shouted 'Eureka!' Without hesitation I constructed a transformer of great power, furnished with a large parabolic mirror to transmit the waves in parallel lines, erected the machinery and buildings here, and when all was ready for the final experiment I telegraphed for you." Prepared by these explanations I was all on fire to see the thing tried. Hall was no less eager, and, calling in his two faithful assistants to make the final adjustments, he led the way into what he facetiously named "the lunar chamber."

"If we fail," he remarked with a smile that had an element of worriment in it, "it will become the 'lunatic chamber'—but no danger of that. You observe this polished silver knob, supported by a metallic rod curved over at the top like a crane. That constitutes the pole from which I propose to transmit the energy to the moon, and upon which I expect the storm of atoms to be centred by reflection from the mirror at whose focus it is placed."

"One moment," I said. "Am I to understand that you think that the moon is a solid mass of artemisium, and that no matter where your radiant force strikes it a 'kathodic pole' will be formed there from which atoms will be projected to the earth?"

"No," said Hall, "I must carefully choose the point on the lunar surface where to operate. But that will present no difficulty. I made up my mind as soon as I had penetrated Syx's secret that he obtained the metal from those mystic white streaks which radiate from Tycho, and which have puzzled the astronomers ever since the invention of telescopes. I now believe those streaks to be composed of immense veins of the metal that Syx has most appropriately named artemisium, which you, of course, recognize as being derived from the name of the Greek goddess of the moon, Artemis, whom the Romans called Diana. But now to work!"

It was less than a day past the time of new moon, and the earth's satellite was too near the sun to be visible in broad daylight. Accordingly, the mirror had to be directed by means of knowledge of the moon's place in the sky. Driven by accurate clockwork, it could be depended upon to retain the proper direction when once set.

With breathless interest I watched the proceedings of my friend and his assistants. The strain upon the nerves of all of us was such as could not have been borne for many hours at a stretch. When everything had been adjusted to his satisfaction, Hall stepped back, not without betraying his excitement in flushed cheeks and flashing eyes, and pressed a lever. The powerful engine underneath the floor instantly responded. The experiment was begun.

"I have set it upon a point about a hundred miles north of Tycho, where the Yerkes photographs show a great abundance of the white substance," said Hall.

Then we waited. A minute elapsed. A bird, fluttering in the opening above, for a second or two, wrenched our strained nerves. Hall's face turned pale.

"They had better keep away from here," he whispered, with a ghastly smile.

Two minutes! I could hear the beating of my heart. The engine shook the floor.

Three minutes! Hall's face was wet with perspiration. The bird blundered in and startled us again.

Four minutes! We were like statues, with all eyes fixed on the polished ball of silver, which shone in the brilliant light concentrated upon it by the mirror.

Five minutes! The shining ball had become a confused blue, and I violently winked to clear my vision.

"At last! Thank God! Look! There it is!"

It was Hall who spoke, trembling like an aspen. The silver knob had changed color. What seemed a miniature rainbow surrounded it, with concentric circles of blinding brilliance.

Then something dropped flashing into an earthen dish set beneath the ball! Another glittering drop followed, and, at a shorter interval, another!

Almost before a word could be uttered the drops had coalesced and become a tiny stream, which, as it fell, twisted itself into a bright spiral, gleaming with a hundred shifting hues, and forming on the bottom of the dish a glowing, interlacing maze of viscid rings and circlets, which turned and twined about and over one another, until they had blended and settled into a button-shaped mass of hot metallic jelly. Hall snatched the dish away, and placed another in its stead.

"This will be about right for a watch charm when it cools," he said, with a return of his customary self-command. "I promised you the first specimen. I'll catch another for myself."

"But can it be possible that we are not dreaming?" I exclaimed. "Do you really believe that this comes from the moon?"

"Just as surely as rain comes from the clouds," cried Hall, with all his old impatience. "Haven't I just showed you the whole process?"

"Then I congratulate you. You will be as rich as Dr. Syx."

"Perhaps," was the unperturbed reply, "but not until I have enlarged my apparatus. At present I shall hardly do more than supply mementoes to my friends. But since the principle is established, the rest is mere detail."

Six weeks later the financial centres of the earth were shaken by the news that a new supply of artemisium was being marketed from a mill which had been secretly opened in the Sierras of California. For a time there was almost a panic. If Hall had chosen to do so, he might have precipitated serious trouble. But he immediately entered into negotiations with government representatives, and the inevitable result was that, to preserve the monetary system of the world from upheaval, Dr. Syx had to consent that Hall's mill should share equally with his in the production of artemisium. During the negotiations the doctor paid a visit to Hall's establishment. The meeting between them was most dramatic. Syx tried to blast his rival with a glance, but knowledge is power, and my friend faced his mysterious antagonist, whose deepest secrets he had penetrated, with an unflinching eye. It was remarked that Dr. Syx became a changed man from that moment. His masterful air seemed to have deserted him, and it was with something resembling humility that he assented to the arrangement which required him to share his enormous gains with his conqueror.

Of course, Hall's success led to an immediate recrudescence of the efforts to extract artemisium from the Syx ore, and, equally of course, every such attempt failed. Hall, while keeping his own secret, did all he could to discourage the experiments, but they naturally believed that he must have made the very discovery which was the subject of their dreams, and he could not, without betraying himself, and upsetting the finances of the planet, directly undeceive them. The consequence was that fortunes were wasted in hopeless experimentation, and, with Hall's achievement dazzling their eyes, the deluded fortune-seekers kept on in the face of endless disappointments and disaster.

And presently there came another tragedy. The Syx mill was blown up! The accident—although many people refused to regard it as an accident, and asserted that the doctor himself, in his chagrin, had applied the match—the explosion, then, occurred about sundown, and its effects were awful. The great works, with everything pertaining to them, and every rail that they contained, were blown to atoms. They disappeared as if they had never existed. Even the twin tunnels were involved in the ruin, a vast cavity being left in the mountain-side where Syx's ten acres had been. The force of the explosion was so great that the shattered rock was reduced to dust. To this fact was owing the escape of the troops camped near. While the mountain was shaken to its core, and enormous parapets of living rock were hurled down the precipices of the Teton, no missiles of appreciable size traversed the air, and not a man at the camp was injured. But Jackson's Hole, filled with red dust, looked for days afterwards like the mouth of a tremendous volcano just after an eruption. Dr. Syx had been seen entering the mill a few minutes before the catastrophe by a sentinel who was stationed about a quarter of a mile away, and who, although he was felled like an ox by the shock, and had his eyes, ears, and nostrils filled with flying dust, miraculously escaped with his life.

After this a new arrangement was made whereby Andrew Hall became the sole producer of artemisium, and his wealth began to mount by leaps of millions towards the starry heights of the billions.

About a year after the explosion of the Syx mill a strange rumor got about. It came first from Budapest, in Hungary, where it was averred several persons of credibility had seen Dr. Max Syx. Millions had been familiar with his face and his personal peculiarities, through actually meeting him, as well as through photographs and descriptions, and, unless there was an intention to deceive, it did not seem possible that a mistake could be made in identification. There surely never was another man who looked just like Dr. Syx. And, besides, was it not demonstrable that he must have perished in the awful destruction of his mill?

Soon after came a report that Dr. Syx had been seen again; this time at Ekaterinburg, in the Urals. Next he was said to have paid a visit to Batang, in the mountainous district of southwestern China, and finally, according to rumor, he was seen in Sicily, at Nicolosi, among the volcanic pimples on the southern slope of Mount Etna.

Next followed something of more curious and even startling interest. A chemist at Budapest, where the first rumors of Syx's reappearance had placed the mysterious doctor, announced that he could produce artemisium, and proved it, although he kept his process secret. Hardly had the sensation caused by this news partially subsided when a similar report arrived from Ekaterinburg; then another from Batang; after that a fourth from Nicolosi!

Nobody could fail to notice the coincidence; wherever the doctor—or was it his ghost?—appeared, there, shortly afterwards, somebody discovered the much-sought secret.

After this Syx's apparitions rapidly increased in frequency, followed in each instance by the announcement of another productive artemisium mill. He appeared in Germany, Italy, France, England, and finally at many places in the United States.

"It is the old doctor's revenge," said Hall to me one day, trying to smile, although the matter was too serious to be taken humorously. "Yes, it is his revenge, and I must admit that it is complete. The price of artemisium has fallen one-half within six months. All the efforts we have made to hold back the flood have proved useless. The secret itself is becoming public property. We shall inevitably be overwhelmed with artemisium, just as we were with gold, and the last condition of the financial world will be worse than the first."

My friend's gloomy prognostications came near being fulfilled to the letter. Ten thousand artemisium mills shot their etheric rays upon the moon, and our unfortunate satellite's metal ribs were stripped by atomic force. Some of the great white rays that had been one of the telescopic wonders of the lunar landscapes disappeared, and the face of the moon, which had remained unchanged before the eyes of the children of Adam from the beginning of their race, now looked as if the blast of a furnace had swept it. At night, on the moonward side, the earth was studded with brilliant spikes, all pointed at the heart of its child in the sky.

But the looting of the moon brought disaster to the robber planet. So mad were the efforts to get the precious metal that the surface of our globe was fairly showered with it, productive fields were, in some cases, almost smothered under a metallic coating, the air was filled with shining dust, until finally famine and pestilence joined hands with financial disaster to punish the grasping world.

Then, at last, the various governments took effective measures to protect themselves and their people. Another combined effort resulted in an international agreement whereby the production of the precious moon metal was once more rigidly controlled. But the existence of a monopoly, such as Dr. Syx had so long enjoyed, and in the enjoyment of which Andrew Hall had for a brief period succeeded him, was henceforth rendered impossible.

THE LAST OF DR. SYX

Many years after the events last recorded I sat, at the close of a brilliant autumn day, side by side with my old friend Andrew Hall, on a broad, vine-shaded piazza which faced the east, where the full moon was just rising above the rim of the Sierra, and replacing the rosy counter-glow of sunset with its silvery radiance. The sight was calculated to carry the minds of both back to the events of former years. But I noticed that Hall quickly changed the position of his chair, and sat down again with his back to the rising moon. He had managed to save some millions from the wreck of his vast fortune when artemisium started to go to the dogs, and I was now paying him one of my annual visits at his palatial home in California.

"Did I ever tell you of my last trip to the Teton?" he asked, as I continued to gaze contemplatively at the broad lunar disk which slowly detached itself from the horizon and began to swim in the clear evening sky.

"No," I replied, "but I should like to hear about it."

"Or of my last sight of Dr. Syx?"

"Indeed! I did not suppose that you ever saw him after that conference in your mill, when he had to surrender half of the world to you."

"Once only I saw him again," said Hall, with a peculiar intonation.

"Pray go ahead, and tell me the whole story."

My friend lighted a fresh cigar, tipped his chair into a more comfortable position, and began:

"It was about seven years ago. I had long felt an unconquerable desire to have another look at the Teton and the scenes amid which so many strange events in my life had occurred. I thought of sending for you to go with me, but I knew you were abroad much of your time, and I could not be certain of catching you. Finally I decided to go alone. I travelled on horseback by way of the Snake River canyon, and arrived early one morning in Jackson's Hole. I can tell you it was a gloomy place, as barren and deserted as some of those Arabian wadies that you have been describing to me. The railroad had long ago been abandoned, and the site of the military camp could scarcely be recognized. An immense cavity with ragged walls showed where Dr. Syx's mill used to send up its plume of black smoke.

"As I stared up the gaunt form of the Teton, whose beetling precipices had been smashed and split by the great explosion, I was seized with a resistless impulse to climb it. I thought I should like to peer off again from that pinnacle which had once formed so fateful a watch-tower for me. Turning my horse loose to graze in the grassy river bottom, and carrying my rope tether along as a possible aid in climbing, I set out for the ascent. I knew I could not get up the precipices on the eastern side, which we were able to master with the aid of our balloon, and so I bore round, when I reached the steepest cliffs, until I was on the southwestern side of the peak, where the climbing was easier.

"But it took me a long time, and I did not reach the rift in the summit until just before sundown. Knowing that it would be impossible for me to descend at night, I bethought me of the enclosure of rocks, supposed to have been made by Indians, on the western pinnacle, and decided that I could pass the night there.

"The perpendicular buttress forming the easternmost and highest point of the Teton's head would have baffled me but for the fact that I found a long crack, probably an effect of the tremendous explosion, extending from bottom to top of the rock. Driving my toes and fingers into this rift, I managed, with a good deal of trouble, and no little peril, to reach the top. As I lifted myself over the edge and rose to my feet, imagine my amazement at seeing Dr. Syx standing within arm's-length of me!

"My breath seemed pent in my lungs, and I could not even utter the exclamation that rose to my lips. It was like meeting a ghost. Notwithstanding the many reports of his having been seen in various parts of the world, it had always been my conviction that he had perished in the explosion.

"Yet there he stood in the twilight, for the sun was hidden by the time I reached the summit, his tall form erect, and his black eyes gleaming under the heavy brows as he fixed them sternly upon my face. You know I never was given to losing my nerve, but I am afraid I lost it on that occasion. Again and again I strove to speak, but it was impossible to move my tongue. So powerless seemed my lungs that I wondered how I could continue breathing.

"The doctor remained silent, but his curious smile, which, as you know, was a thing of terror to most people, overspread his black-rimmed face and was broad enough to reveal the gleam of his teeth. I felt that he was looking me through and through. The sensation was as if he had transfixed me with an ice-cold blade. There was a gleam of devilish pleasure in his eyes, as though my evident suffering was a delight to him and a gratification of his vengeance. At length I succeeded in overcoming the feeling which oppressed me, and, making a step forward, I shouted in a strained voice,

"'You black Satan!'

"I cannot clearly explain the psychological process which led me to utter those words. I had never entertained any enmity towards Dr. Syx, although I had always regarded him as a heartless person, who had purposely led thousands to their ruin for his selfish gain, but I knew that he could not help hating me, and I felt now that, in some inexplicable manner, a struggle, not physical, but spiritual, was taking place between us, and my exclamation, uttered with surprising intensity, produced upon me, and apparently upon him, the effect of a desperate sword thrust which attains its mark.

"Immediately the doctor's form seemed to recede, as if he had passed the verge of the precipice behind him. At the same time it became dim, and then dimmer, until only the dark outlines, and particularly the jet-black eyes, glaring fiercely, remained visible. And still he receded, as though floating in the air, which was now silvered with the evening light, until he appeared to cross the immense atmospheric gulf over Jackson's Hole and paused on the rim of the horizon in the east.

"Then, suddenly, I became aware that the full moon had risen at the very place on the distant mountain-brow where the spectre rested, and as I continued to gaze, as if entranced, the face and figure of the doctor seemed slowly to frame themselves within the lunar disk, until at last he appeared to have quitted the air and the earth and to be frowning at me from the circle of the moon."

While Hall was pronouncing his closing words I had begun to stare at the moon with swiftly increasing interest, until, as his voice stopped, I exclaimed,

"Why, there he is now! Funny I never noticed it before. There's Dr. Syx's face in the moon, as plain as day."

"Yes," replied Hall, without turning round, "and I never like to look at it."
