me of his plans.
“There’s a natural explanation, of course,” he said. “My theory is that the moon rock is of some composition sensitive to the action of moon rays; somewhat as the metal selenium is to sun rays. The little circles over the top are, without doubt, its operating agency. When the light strikes them they release the mechanism that opens the slab, just as you can open doors with sun or electric light by an ingenious arrangement of selenium-cells. Apparently it takes the strength of the full moon both to do this and to summon the Dweller in the Pool. We will first try a concentration of the rays of the waning moon upon these circles to see whether that will open the rock. If it does we will be able to investigate the Pool without interruption from — from — what emanates.
“Look, here on the chart are their locations. I have made this in duplicate for you in the event — of something happening — to me. And if I lose — you’ll come after us, Goodwin, with help — won’t you?”
And again I promised.
A little later he complained of increasing sleepiness.
“But it’s just weariness,” he said. “Not at all like that other drowsiness. It’s an hour till moonrise still,” he yawned at last. “Wake me up a good fifteen minutes before.”
He lay upon the berth. I sat thinking. I came to myself with a guilty start. I had completely lost myself in my deep preoccupation. What time was it? I looked at my watch and jumped to the port-hole. It was full moonlight; the orb had been up for fully half an hour. I strode over to Throckmartin and shook him by the shoulder.
“Up, quick, man!” I cried. He rose sleepily. His shirt fell open at the neck and I looked, in amazement, at the white band around his chest. Even under the electric light it shone softly, as though little flecks of light were in it.
Throckmartin seemed only half-awake. He looked down at his breast, saw the glowing cincture, and smiled.
“Yes,” he said drowsily, “it’s coming — to take me back to Edith! Well, I’m glad.”
“Throckmartin!” I cried. “Wake up! Fight!”
“Fight!” he said. “No use; come after us!”
He went to the port and sleepily drew aside the curtain. The moon traced a broad path of light straight to the ship. Under its rays the band around his chest gleamed brighter and brighter; shot forth little rays; seemed to writhe.
The lights went out in the cabin; evidently also throughout the ship, for I heard shoutings above.
Throckmartin still stood at the open port. Over his shoulder I saw a gleaming pillar racing along the moon path toward us. Through the window cascaded a blinding radiance. It gathered Throckmartin to it, clothed him in a robe of living opalescence. Light pulsed through and from him. The cabin filled with murmurings —
A wave of weakness swept over me, buried me in blackness. When consciousness came back, the lights were again burning brightly.
But of Throckmartin there was no trace!
CHAPTER VI
“THE SHINING DEVIL TOOK THEM!”
My colleagues of the Association, and you others who may read this my narrative, for what I did and did not when full realization returned I must offer here, briefly as I can, an explanation; a defense — if you will.
My first act was to spring to the open port. The coma had lasted hours, for the moon was now low in the west! I ran to the door to sound the alarm. It resisted under my frantic hands; would not open. Something fell tinkling to the floor. It was the key and I remembered then that Throckmartin had turned it before we began our vigil. With memory a hope died that I had not known was in me, the hope that he had escaped from the cabin, found refuge elsewhere on the ship.
And as I stooped, fumbling with shaking fingers for the key, a thought came to me that drove again the blood from my heart, held me rigid. I could sound no alarm on the Southern Queen for Throckmartin!
Conviction of my appalling helplessness was complete. The ensemble of the vessel from captain to cabin boy was, to put it conservatively, average. None, I knew, save Throckmartin and myself had seen the first apparition of the Dweller. Had they witnessed the second? I did not know, nor could I risk speaking, not knowing. And not seeing, how could they believe? They would have thought me insane — or worse; even, it might be, his murderer.
I snapped off the electrics; waited and listened; opened the door with infinite caution and slipped, unseen, into my own stateroom. The hours until the dawn were eternities of waking nightmare. Reason, resuming sway at last, steadied me. Even had I spoken and been believed where in these wastes after all the hours could we search for Throckmartin? Certainly the captain would not turn back to Port Moresby. And even if he did, of what use for me to set forth for the Nan–Matal without the equipment which Throckmartin himself had decided was necessary if one hoped to cope with the mystery that lurked there?
There was but one thing to do — follow his instructions; get the paraphernalia in Melbourne or Sydney if it were possible; if not sail to America as swiftly as might be, secure it there and as swiftly return to Ponape. And this I determined to do.
Calmness came back to me after I had made this decision. And when I went up on deck I knew that I had been right. They had not seen the Dweller. They were still discussing the darkening of the ship, talking of dynamos burned out, wires short circuited, a half dozen explanations of the extinguishment. Not until noon was Throckmartin’s absence discovered. I told the captain that I had left him early in the evening; that, indeed, I knew him but slightly, after all. It occurred to none to doubt me, or to question me minutely. Why should it have? His strangeness had been noted, commented upon; all who had met him had thought him half mad. I did little to discourage the impression. And so it came naturally that on the log it was entered that he had fallen or leaped from the vessel some time during the night.
A report to this effect was made when we entered Melbourne. I slipped quietly ashore and in the press of the war news Throckmartin’s supposed fate won only a few lines in the newspapers; my own presence on the ship and in the city passed unnoticed.
I was fortunate in securing at Melbourne everything I needed except a set of Becquerel ray condensers — but these were the very keystone of my equipment. Pursuing my search to Sydney I was doubly fortunate in finding a firm who were expecting these very articles in a consignment due them from the States within a fortnight. I settled down in strictest seclusion to await their arrival.
And now it will occur to you to ask why I did not cable, during this period of waiting, to the Association; demand aid from it. Or why I did not call upon members of the University staffs of either Melbourne or Sydney for assistance. At the least, why I did not gather, as Throckmartin had hoped to do, a little force of strong men to go with me to the Nan–Matal.
To the first two questions I answer frankly — I did not dare. And this reluctance, this inhibition, every man jealous of his scientific reputation will understand. The story of Throckmartin, the happenings I had myself witnessed, were incredible, abnormal, outside the facts of all known science. I shrank from the inevitable disbelief, perhaps ridicule — nay, perhaps even the graver suspicion that had caused me to seal my lips while on the ship. Why I myself could only half believe! How then could I hope to convince others?
And as for the third question — I could not take men into the range of such a peril without first warning them of what they might encounter; and if I did warn them —
It was checkmate! If it also was cowardice — well, I have atoned for it. But I do not hold it so; my conscience is clear.
That fortnight and the greater part of another passed before the ship I awaited steamed into port. By that time, between my straining anxiety to be after Throckmartin, the despairing thought that every moment of delay might be vital to him and his, and my intensely
