"It's easy enough to explain, Larry," I said. "The effect, that is--for what the green ray is made of I don't know, of course. But what it does, clearly, is stimulate atomic vibration to such a pitch that the cohesion between the particles of matter is broken and the body flies to bits--just as a fly-wheel does when its speed gets so great that the particles of which _it_ is made can't hold together."

"Shake themselves to pieces is right, then!" he exclaimed.

"Absolutely right," I nodded. "Everything in Nature vibrates. And all matter--whether man or beast or stone or metal or vegetable--is made up of vibrating molecules, which are made up of vibrating atoms which are made up of truly infinitely small particles of electricity called electrons, and electrons, the base of all matter, are themselves perhaps only a vibration of the mysterious ether.

"If a magnifying gla.s.s of sufficient size and strength could be placed over us we could see ourselves as sieves--our s.p.a.ce lattice, as it is called. And all that is necessary to break down the lattice, to shake us into nothingness, is some agent that will set our atoms vibrating at such a rate that at last they escape the unseen cords and fly off.

"The green ray of Yolara is such an agent. It set up in the dwarf that incredibly rapid rhythm that you saw and--shook him not to atoms--but to electrons!"

"They had a gun on the West Front--a seventy-five," said O'Keefe, "that broke the eardrums of everybody who fired it, no matter what protection they used. It looked like all the other seventy-fives--but there was something about its sound that did it. They had to recast it."

"It's practically the same thing," I replied. "By some freak its vibratory qualities had that effect. The deep whistle of the sunken Lusitania would, for instance, make the Singer Building shake to its foundations; while the Olympic did not affect the Singer at all but made the Woolworth shiver all through. In each case they stimulated the atomic vibration of the particular building--"

I paused, aware all at once of an intense drowsiness. O'Keefe, yawning, reached down to unfasten his puttees.

"Lord, I'm sleepy!" he exclaimed. "Can't understand it--what you say--most--interesting--Lord!" he yawned again; straightened. "What made Reddy take such a shine to the Russian?" he asked.

"Thanaroa," I answered, fighting to keep my eyes open.

"What?"

"When Lugur spoke that name I saw Marakinoff signal him. Thanaroa is, I suspect, the original form of the name of Tangaroa, the greatest G.o.d of the Polynesians. There's a secret cult to him in the islands.

Marakinoff may belong to it--he knows it anyway. Lugur recognized the signal and despite his surprise answered it."

"So he gave him the high sign, eh?" mused Larry. "How could they both know it?"

"The cult is a very ancient one. Undoubtedly it had its origin in the dim beginnings before these people migrated here," I replied. "It's a link--one--of the few links between up there and the lost past--"

"Trouble then," mumbled Larry. "h.e.l.l brewing! I smell it--Say, Doc, is this sleepiness natural? Wonder where my--gas mask--is--" he added, half incoherently.

But I myself was struggling desperately against the drugged slumber pressing down upon me.

"Lakla!" I heard O'Keefe murmur. "Lakla of the golden eyes--no Eilidh--the Fair!" He made an immense effort, half raised himself, grinned faintly.

"Thought this was paradise when I first saw it, Doc," he sighed. "But I know now, if it is, No-Man's Land was the greatest place on earth for a honeymoon. They--they've got us, Doc--" He sank back. "Good luck, old boy, wherever you're going." His hand waved feebly.

"Glad--knew--you. Hope--see--you--'gain--"

His voice trailed into silence. Fighting, fighting with every fibre of brain and nerve against the sleep, I felt myself being steadily overcome. Yet before oblivion rushed down upon me I seemed to see upon the grey-screened wall nearest the Irishman an oval of rosy light begin to glow; watched, as my falling lids inexorably fell, a flame-tipped shadow waver on it; thicken; condense--and there looking down upon Larry, her eyes great golden stars in which intensest curiosity and shy tenderness struggled, sweet mouth half smiling, was the girl of the Moon Pool's Chamber, the girl whom the green dwarf had named--Lakla: the vision Larry had invoked before that sleep which I could no longer deny had claimed him--

Closer she came--closer---the eyes were over us.

Then oblivion indeed!

CHAPTER XVI

Yolara of Muria vs. the O'Keefe

I awakened with all the familiar, homely sensation of a shade having been pulled up in a darkened room. I thrilled with a wonderful sense of deep rest and restored resiliency. The ebon shadow had vanished from above and down into the room was pouring the silvery light. From the fountain pool came a mighty splashing and shouts of laughter. I jumped and drew the curtain. O'Keefe and Rador were swimming a wild race; the dwarf like an otter, out-distancing and playing around the Irishman at will.

Had that overpowering sleep--and now I confess that my struggle against it had been largely inspired by fear that it was the abnormal slumber which Throckmartin had described as having heralded the approach of the Dweller before it had carried away Thora and Stanton--had that sleep been after all nothing but natural reaction of tired nerves and brains?

And that last vision of the golden-eyed girl bending over Larry? Had that also been a delusion of an overstressed mind? Well, it might have been, I could not tell. At any rate, I decided, I would speak about it to O'Keefe once we were alone again--and then giving myself up to the urge of buoyant well-being I shouted like a boy, stripped and joined the two in the pool. The water was warm and I felt the unwonted tingling of life in every vein increase; something from it seemed to pulse through the skin, carrying a clean vigorous vitality that toned every fibre. Tiring at last, we swam to the edge and drew ourselves out. The green dwarf quickly clothed himself and Larry rather carefully donned his uniform.

"The Afyo Maie has summoned us, Doc," he said. "We're to--well--I suppose you'd call it breakfast with her. After that, Rador tells me, we're to have a session with the Council of Nine. I suppose Yolara is as curious as any lady of--the upper world, as you might put it--and just naturally can't wait," he added.

He gave himself a last shake, patted the automatic hidden under his left arm, whistled cheerfully.

"After you, my dear Alphonse," he said to Rador, with a low bow. The dwarf laughed, bent in an absurd imitation of Larry's mocking courtesy and started ahead of us to the house of the priestess. When he had gone a little way on the orchid-walled path I whispered to O'Keefe:

"Larry, when you were falling off to sleep--did you think you saw anything?"

"See anything!" he grinned. "Doc, sleep hit me like a Hun sh.e.l.l. I thought they were pulling the gas on us. I--I had some intention of bidding you tender farewells," he continued, half sheepishly. "I think I did start 'em, didn't I?"

I nodded.

"But wait a minute--" he hesitated. "I had a queer sort of dream--"

"'What was it?" I asked eagerly,

"Well," he answered slowly, "I suppose it was because I'd been thinking of--Golden Eyes. Anyway, I thought she came through the wall and leaned over me--yes, and put one of those long white hands of hers on my head--I couldn't raise my lids--but in some queer way I could see her. Then it got real dreamish. Why do you ask?"

Rador turned back toward us,

"Later," I answered, "Not now. When we're alone."

But through me went a little glow of rea.s.surance. Whatever the maze through which we were moving; whatever of menacing evil lurking there--the Golden Girl was clearly watching over us; watching with whatever unknown powers she could muster.

We pa.s.sed the pillared entrance; went through a long bowered corridor and stopped before a door that seemed to be sliced from a monolith of pale jade--high, narrow, set in a wall of opal.

Rador stamped twice and the same supernally sweet, silver bell tones of--yesterday, I must call it, although in that place of eternal day the term is meaningless--bade us enter. The door slipped aside. The chamber was small, the opal walls screening it on three sides, the black opacity covering it, the fourth side opening out into a delicious little walled garden--a ma.s.s of the fragrant, luminous blooms and delicately colored fruit. Facing it was a small table of reddish wood and from the omnipresent cushions heaped around it arose to greet us--Yolara.

Larry drew in his breath with an involuntary gasp of admiration and bowed low. My own admiration was as frank--and the priestess was well pleased with our homage.

She was swathed in the filmy, half-revelant webs, now of palest blue.

The corn-silk hair was caught within a wide-meshed golden net in which sparkled tiny brilliants, like blended sapphires and diamonds. Her own azure eyes sparkled as brightly as they, and I noted again in their clear depths the half-eager approval as they rested upon O'Keefe's lithe, well-knit figure and his keen, clean-cut face. The high-arched, slender feet rested upon soft sandals whose gauzy withes laced the exquisitely formed leg to just below the dimpled knee.

"Some giddy wonder!" exclaimed Larry, looking at me and placing a hand over his heart. "Put her on a New York roof and she'd empty Broadway.

Take the cue from me, Doc."

He turned to Yolara, whose face was somewhat puzzled.

"I said, O lady whose shining hair is a web for hearts, that in our world your beauty would dazzle the sight of men as would a little woman sun!" he said, in the florid imagery to which the tongue lends itself so well.

A flush stole up through the translucent skin. The blue eyes softened and she waved us toward the cushions. Black-haired maids stole in, placing before us the fruits, the little loaves and a steaming drink somewhat the colour and odor of chocolate. I was conscious of outrageous hunger.

"What are you named, strangers?" she asked.
