And, grouped around this, already some hundreds of the now paling torches cast their livid glare.

Off to one side he could just distinguish what seemed to be a group engaged in some activity--but what this might be, he could not determine. Yet, all at once a scream of pain burst out, therefrom; and then a gasping cry that ended quickly and did not come again.

Another shriek, and still a third; and now into the leaping flames some dark, misshapen things were flung, and a great shout arose.

Then rose, also, a shrill, singsong whine; and suddenly drams roared, now with a different cadence.

"Hark!" said the engineer. "The torchmen must have exterminated the other bunch, and got possession of the drums. They're using 'em, themselves--and badly!"

By the firelight vague shapes came and went, their shadows grotesquely flung against the leafy screens. The figures quickened their paces and their gestures; then suddenly, with cries, flung themselves into wild activity. And all about the fire, Stern saw a wheeling, circling, eddying mob of black and frightful shapes.

"The swine!" he breathed. "Wait--wait till I make a pint or two of Pulverite!"

Even as he spoke, the concourse grew quiet with expectancy. A silence fell upon the forest. Something was being led forward toward the fire--something, for which the others all made way.

The wind freshened. With it, increased the volume of smoke. Another frightened bird, cheeping forlornly, fluttered above the tree-tops.

Then rose a cry, a shriek long-drawn and ghastly, that climbed till it broke in a bubbling, choking gasp.

Came a sharp clicking sound, a quick scuffle, a grunt; then silence once more.

And all at once the drums crashed; and the dance began again, madder, more obscenely hideous than ever.

"Voodoo!" gulped Stern. "Obeah-work! And--and the quicker I get my Pulverite to working, the better!"

Undecided no longer, determined now on a course of definite action without further delay, the engineer turned back into the room. Upon his forehead stood a cold and p.r.i.c.kling sweat, of horror and disgust.

But to his lips he forced a smile, as, in the half light of the red and windy dawn, he drew close to Beatrice.

Then all at once, to his unspeakable relief, he saw the girl was sleeping.

Utterly worn out, exhausted and spent with the long strain, the terrible fatigues of the past thirty-six hours, she had lain down and had dropped off to sleep. There she lay at full length. Very beautiful she looked, half seen in the morning gloom. One arm crossed her full bosom; the other pillowed her cheek. And, bending close, Stern watched her a long minute.

With strange emotion he heard her even breathing; he caught the perfume of her warm, ripe womanhood. Never had she seemed to him so perfect, so infinitely to be loved, to be desired.

And at thought of that beast-horde in the wood below, at realization of what _might_ be, if they two should chance to be discovered and made captive, his face went hard as iron. An ugly, savage look possessed him, and he clenched both fists.

For a brief second he stooped still closer; he laid his lips soundlessly, gently upon her hair. And when again he stood up, the look in his eyes boded scant good to anything that might threaten the sleeping girl.

"So, now to work!" said he.

Into his own room he stepped quietly, his room where he had collected his various implements and chemicals. First of all he set out, on the floor, a two-quart copper tea-kettle; and beside this, choosing carefully, he ranged the necessary ingredients for a "making" of his secret explosive.

"Now, the wash-out water," said he, taking another larger dish.

Over to the water-pail he walked. Then he stopped, suddenly, frowning a black and puzzled frown.

"What?" he exclaimed. "But--there isn't a pint left, all together!

Hem! Now then, here _is_ a situation."

Hastily he recalled how the great labors of the previous day, the wireless experiments and all, had prevented him from going out to the spring to replenish his supply. Now, though he bitterly cursed himself for his neglect, that did no good. The fact remained, there was no water.

"Scant pint, maybe!" said he. "And I've got to have a gallon, at the very least. To say nothing of drink for two people! _And_ the horde, there, camping round the spring. Je-ru-salem!"

Softly he whistled to himself; then, trying to solve this vital, unexpected problem, fell to pacing the floor.

Day, slowly looming through the window, showed his features set and hard. Close at hand, the breath of morning winds stirred the treetops.

But of the usual busy twitter and gossip of birds among the branches, now there was none. For down below there, in the forest, the ghoulish vampire revels still held sway.

Stern, at a loss, swore hotly under his breath.

Then suddenly he found himself; he came to a decision.

"_I'm_ going down," he vowed. "I'm going down, to _see!_"

CHAPTER XVIII

THE SUPREME QUESTION

Now that his course lay clear before him, the man felt an instant and a huge relief. Whatever the risks, the dangers, this adventuring was better than a mere inaction, besieged there in the tower by that ugly, misshapen horde.

First of all, as he had done on the first morning of the awakening, when he had left the girl asleep, he wrote a brief communication to forestall any possible alarm on her part. This, scrawled with charcoal on a piece of smooth hide, ran:

"Have had to go down to get water and lay of the land. Absolutely necessary. Don't be afraid. Am between you and them, well armed. Will leave you both the rifle and the shotgun. Stay here, and have no fear.

Will come back as soon as possible. ALLAN."

He laid this primitive letter where, on awakening, she could not fail to see it. Then, making sure again that all the arms were fully charged, he put the rifle and the gun close beside his "note," and saw to it that his revolvers lay loosely and conveniently in the holsters she had made for him.

One more reconnaissance he made at the front window. This done, he took the water-pail and set off quietly down the stairs. His feet were noiseless as a cat's.

At every landing he stopped, listening intently. Down, ever down, story by story he crept.

To his chagrin--though he had half expected worse--he found that the boiler-explosion of the previous night had really made the way impa.s.sible, from the third story downward. These lowest flights of steps had been so badly broken, that now they gave no access to the arcade.

All that remained of them was a jumbled ma.s.s of wreckage, below the gaping hole in the third-floor hallway.

"_That_ means," said Stern to himself, "I've got to find another way down. And quick, too!"

He set about the task with a will. Exploration of several lateral corridors resulted in nothing; but at last good fortune led him to stairs that had remained comparatively uninjured. And down these he stole, pail in one hand, revolver ready in the other, listening, creeping, every sense alert.

He found himself, at length, in the shattered and dismembered wreckage of the once-famed "Marble Court." Fallen now were the carved and gilded pillars; gone, save here or there for a fragment, the wondrous bal.u.s.trade. One of the huge newel-posts at the bottom lay on the cracked floor of marble squares; the other, its metal chandelier still clinging to it, lolled drunkenly askew.

But Stern had neither time nor inclination to observe these woful changes. Instead, he pressed still forward, and, after a certain time of effort, found himself in the arcade once more.

Here the effects of the explosion were very marked. A ghastly hole opened into the subcellar below; ma.s.ses of fallen ceiling blocked the way; and every pane of gla.s.s in the shop-fronts had shattered down.

Smoke had blackened everything. Ashes and dirt, ad infinitum, completed the dreary picture, seen there by the still insufficient light of morning.
