"But I was of different stuff. Power's notes had given me a few ideas of my own. For fifteen years, though I followed the profession for which I had trained myself, I worked, studied, and experimented. At last I felt that I, too, had solved a problem, not of this dust, the secret of which passed with its creator, but of a means to recover the original vibratory rhythm after it had been altered by the dust, that is, a means to return to our own world.

"I am proud to say that I had the courage to make the trial. I too, have wandered across the wide Ulithian plain. I, too, have passed the Gateway of the Moon into places and amid peoples more strange than even you can dream. The thought of those wanderings became to me an obsession. I was like a drug fiend, who can neither rest nor sleep unless he knows that the means are at hand to rebuild his dream castles-reanimate his wondrous and seductive houris.

"But the time came when my share of the dust was at last exhausted. Naturally I went to Crane. I think I hinted to you that he was a superstitious fool. He had bought that vial, the Cerberus, and he dumped out the absurdly impossible relic of Dante, replacing it with Power's stuff. 'Dust from the Rocks of Purgatory' appealed to him, I suppose, as better applicable to this powder than to the very earthy dust the vial had before contained.

"Well, I found Crane utterly unapproachable on the subject. I begged, pleaded, threatened, offered him all in my power to give; but he would not let me have it. At his death I was wild with rage when I learned of its sale to a mere collector of curios. You know the rest of that episode. Can you blame me now?

"To-day science herself is steadily approaching the magic boundaries of those realms which were once my familiar playground. Soon she can no longer ignore the actual, material existence of the 'astral plane' as it has been misnamed by investigators who only recognize it as a Psychical possibility.

"But I-in the flesh, I have known such adventures as only you in all the world would credit! There, ever changing, continually forming, are born the nuclei of events, conditions, inventions, ideas, which later 'break through' as it were and recreate this more stable world to which we are born. The inspiration of the poet, the philosopher, or the inventor, is no more than a flicker from that swifter, different vibration within our own.

"And those lands have their monsters-devils, even. The spirit can at times attune itself and in our world a prophet arises. But let him beware! They are wild realms which he glimpses, neither good nor bad, but alive with their own never-ceasing, half-aimless, half-purposeful activities. I know them as no other man save Andrew Power alone. Many times have I sought him there. Many times has his name come up in some such fantastic connection at it came to you. I have seen, as it were, the shadow of his thought sketched in the tangible phantasmagoria which surrounded me. But either he eludes me purposely, or he is dead, and only his mind endures as an invisible force. But if he still lives and we meet, he can make this stuff that I can't make; I can show him the way back to our own world; and after that the door will be open for all to pass!

"Think of the discoveries that will be hastened-the miracles that may be wrought by knowledge acquired at first hand across that threshold! I could almost kill myself for sheer rage when I think how I wasted glorious opportunities in the pursuit of mere unprofitable adventure! Why, you yourselves brought back at least one idea-the idea of matter-destroying sound waves. Had it been Andrew Power or I, we would have searched those archives until we found the formula by which the Red Bell was made. We would have brought that back, instead of the bare and useless idea!"

"And a fine lot of good that would have been to the world!" exploded Trenmore. "I'd as soon give matches to a child and bid it go play in the nice powder mill, as turn loose the men of this world in that one we've come from, if all you say is true. This dust here I'll toss in the river, so no man shall go that road again. 'Tis not right nor decent, Mr. Scarboro, that one should so thrust oneself into the very workshop of the Almighty!"

By the gleam in Scarboro's eye hostilities threatened.
