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 eager desire to know whether that shining, glorious horror on the moon path did exist or had been hallucination, I was worn almost to the edge of madness.
