To Beatrice he spoke no word of his occasional uneasiness, nor yet to the old man. Yet one of the very first matters he attended to was the overhauling of the revolvers, which had been rescued out of the melee of the battle and been given to the patriarch, who had kept them with a kind of religious devotion.

Stern put in half a day cleaning and oiling the weapons. He found there still remained a hundred and six cartridges in his bandolier and the girl's. These he now looked upon as his most precious treasure. He divided them equally with Beatrice, and bade her never go out unless she had her weapon securely belted on.

Their life at home was simple in the extreme. Beatrice had the inner room of the hut for her own. Stern and the patriarch occupied the outer one. And there, often far into the hours of the sleeping-time, when Beatrice was resting within, he and the old man talked of the wonders of the past, of the outer world, of old traditions, of the abyss, and a thousand fascinating speculations.

Particularly did the old man seek to understand some notions of the lost machine on which the strangers had come from the outer world; but, though Stern tried most patiently to make him grasp the principle of the mechanism, he failed. This talk, however, set Stern thinking very seriously about the biplane; and he asked a score of questions relative to the qualities of the native oil, to currents in the sea, locations, depths, and so on.

All that he could learn he noted mentally with the precision of the trained engineer.

With accurate scientific observation he at once began to pile up information about the people and the village, the sea, the abyss--everything, in fact, that he could possibly learn. He felt that everything depended on a sound understanding of the topography and nature of the incredible community where he and the girl now found themselves--perhaps for a life stay.

Beatrice and he were clad now like the Folk; wore their hair twisted in similar fashion and fastened with heavy pins or spikes of gold, cleverly graven; were shod with sandals like theirs, made of the skin of a shark-like fish; and carried torches everywhere they went--torches of dried weed, close-packed in a metal basket and impregnated with oil.

This oil particularly interested Stern. Its peculiar blue flame struck him as singular in the extreme. It had, moreover, the property of burning a very long time without being replenished. A wick immersed in it was never consumed or even charred, though the heat produced was intense.

"If I can't set up some kind of apparatus to distil that into gas-engine fuel, I'm no engineer, that's all," said Stern to himself.

"All in time, all in time--but first I must take thought how to raise the old Pauillac from the sea."

Already the newcomers' lungs had become absolutely accustomed to the condensed air, so that they breathed with entire ease and comfort.

They even found this air unusually stimulating and revivifying, because of its greater amount of oxygen to the cubic unit; and thus they were able to endure greater exertions than formerly on the surface of the earth.

The air never grew foul. A steady current set in the direction that Stern's pocket-compa.s.s indicated as north. The heat no longer oppressed them; they were even getting used to the constant fog and to the darkness; and already could see far better than a fortnight previously, when they had arrived.

Stern never could have believed he could learn to do without sunlight and starlight and the free winds of heaven; but now he found that even these were not essential to human life.

Certain phenomena excited his scientific interest very keenly--such as the source of the great gas-flare in the village, the rhythmic variations in the air-current, the small but well-marked tides on the sea, the diminished force of gravitation--indicating a very great depth, indeed, toward the center of the earth--the greater density of the seawater, the heavy vaporization, certain singular rock-strata of the cliffs near the village, and many other matters.

All these Stern promised himself he would investigate as soon as time and strength allowed.

The village itself, he soon determined, was about half a mile long and perhaps a quarter-mile across, measuring from the fortified gate directly back to the huge flame near the dungeon and the place of bones.

He found, incidentally, that more than one hundred and sixty freshly boiled and headless skeletons were now dangling from the iron rods, but wisely held his peace concerning them. Nor did the patriarch volunteer any information about the loss of life of the Folk in the battle. Stern estimated there were now some fifteen hundred people, men, women and children, still remaining in the community; but since he knew nothing of their number when he had arrived, he could not form more than a rough idea of the total slaughter.

He found, however, on one of his excursions outside the walls--which at a distance of two hundred and fifty yards from the sea stretched in a vast irregular arc ab.u.t.ting at each end against the cliff--the graveyard of the Folk.

This awesome and peculiar place consisted of heaps of smooth black boulders piled upon the dead, each heap surmounted by a stone with some crude emblem cut upon it, such as a circle, a square, a cl.u.s.ter of dots, even the rude figure of a bird, a fish, a tortoise, and so on.

Certain of the figures he could make nothing of; but he concluded rightly they were totem-signs, and that they represented all which still remained of the art of writing among those barbarous remnants of the once dominant, powerful and highly cultured race of Americans.

He counted more than two hundred freshly built piles of stone, but whether any of these contained more than one body of the Folk he could, of course, not tell. Allowing, however, that only two hundred of the Folk and one hundred and sixty of the Lanskaarn had fallen, he readily perceived that the battle had been, for intensity and high percentage of killing, sanguinary beyond all battles of his own time.

Under the walls, too, the vast numbers of boulders which had been thrown down, the debris of broken weapons, long and jaggedly barbed iron spear-points and so on, indicated the military ardor and the boldness of the fighting men he now had to dominate and master.

And in his soul he knew the problem of taming, civilizing, saving this rude and terrible people, was certainly the very greatest ever given into the hands of one man and one woman, since time began!

Along the beach he found a goodly number of empty revolver-sh.e.l.ls.

These he picked up, for possible reloading, in case he should be able at some later time to manufacture powder and some fulminating mixture.

He asked the patriarch to have search made for all such empty sh.e.l.ls.

The Folk eagerly and intelligently cooperated.

With interest he watched the weird sight of scores of men with torches rolling the great stones about, seeking for the precious cartridges.

From the beach they tossed the sh.e.l.ls up to him as he walked along the top of the fortifications so lately the scene of horrible combat; and despite him his heart swelled with pride in his breast, to be already directing them in some concerted labor, even so slight as this.

Save for some such interruption, the life of the community had now settled back into its accustomed routine.

With diminished numbers, but indomitable energy, the Folk went on with their daily tasks. Stern concluded the great funeral ceremony, which must have taken place over the fallen defenders, and the horrible rites attending the decapitation, boiling, and hanging up of the trophies of war, the Lanskaarn skeletons, certainly must have formed a series of barbaric pictures more ghastly than any drug-fiend's most diabolical nightmare. He thanked G.o.d that the girl had been spared these frightful scenes.

He could get the old man to tell him nothing concerning these terrific ceremonies. But he discovered, some thirty yards to southward of the circle of stone posts, a boiling geyserlike pool in the rock floor, whence the thick steam continually arose, and which at times burst up in terrific seething.

Here his keen eye detected traces of the recent rites. Here, he knew, the enemies' corpses--and perhaps even some living captives--had been boiled.

And as he stood on the sloping, slippery edge of the great natural caldron, a pit perhaps forty feet in diameter--its margins all worn smooth and greasy by innumerable feet--he shuddered in his soul.

"Good G.o.d!" thought he. "Imagine being flung in there!"

What was it, premonition or sheer repulsion, that caused him, brave as he was, to turn away with a peculiar and intense horror?

Try as he might, he could not banish from his mind the horrible picture of that boiling vat as it must have looked, crammed to the lip with the tumbling, crowding bodies of the dead.

He seemed still to hear the groans of the wounded, the shrieks of the prisoners being dragged thither, being hurled into the spumy, scalding water.

And in his heart he half despaired of ever bringing back to civilization a people so wild and warlike, so cruel, so barbarous as these abandoned People of the Abyss.

Could he have guessed what lay in store for Beatrice and himself should Kamrou, returning, find them still there, a keener and deadlier fear would have possessed his soul.

But of Kamrou he knew nothing yet. Even the chief's name he had not heard. And the patriarch, for reasons of his own, had not yet told the girl a tenth part of the threatening danger.

Even what he had told, he had forbidden her--for Allan's own sake--to let him know.

Thus in a false and fancied sense of peace and calm security, Stern made his observations, laid his plans, and day by day once more came back toward health and strength again.

And day by day the unknown peril drew upon them both.

CHAPTER x.x.xI

ESCAPE?

Who could, indeed, suspect aught of this threatening danger?

Outwardly all now was peaceful. Each waking-time the fishers put forth in their long boats of metal strips covered with fish-skins. Every sleeping-time they returned laden with the fish that formed the princ.i.p.al staple of the community.

The weaving of seaweed fiber, the making of mats, blankets, nets and slings went on as probably for many centuries before.

At forges here and there, where gas-wells blazed, the smiths of the Folk shaped their iron implements or worked most skillfully in gold and copper; and the ringing of the hammers, through the dim-lit gloom around the strange blue fires, formed a chorus fit for Vulcan or the tempering of Siegfried's master-sword.

Stern took occasion to visit many of the huts. They were all similar.
