The Moon Metal Part 8

"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 pa.s.s 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 pa.s.sed 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 pa.s.sed 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 amus.e.m.e.nt."

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."

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?"
