Nine o'clock found them once more on the wing. Stern laid a southerly course along the edge of the Abyss. He and Beatrice had definitely decided that the new home of humanity was not to be the distant regions of the East, involving so long and perilous a journey, but rather some location in the vast, warm, central plain of what had once been the United States.

They judged they were now somewhere in the one-time State of Indiana, not far from Indianapolis. So much warmer had the climate grown that for some months to come at least the Folk could without doubt accustom themselves to the change from the hot and muggy atmosphere of the Abyss to the semitropic heat.

The main object now was to discover suitable caves near a good water supply, where by night the Folk could prosecute their accustomed fisheries. Agriculture and the care of domestic animals by daylight would have to be postponed for some time, possibly for a year or more.

Above all, the health of the prospective colonists must be safeguarded.

It was not until nearly nightfall of the next day, and after stops had been made at the ruins of two considerable but unidentified towns--for fuel, as well as to fit up an electric search-light and hooded lamps to illuminate the instruments in the Abyss--that the explorers found what they were seeking.

About half past five that afternoon they sighted a very considerable river, flowing westward down a rugged and irregular valley, in the direction of the chasm.

"This can't be the Ohio," judged Stern. "We must have long since pa.s.sed its bed, now probably dried up. I don't remember any such hilly region as this in the old days along the Mississippi Valley. All these formations must be the result of the cataclysm. Well, no matter, just so we find what we're after."

"Where are we now?" she asked, peering downward anxiously. "Over what State--can you tell?"

"Probably Tennessee or northern Alabama. See the change in vegetation?

No conifers here, but many palms and fern-trees, and new, strange growths. Fertile isn't the name for it! Once we clear some land here, crops will grow themselves! I don't think we'll do better than this, Beta. Shall we land and see?"

A quarter-hour later the Pauillac had safely deposited them on a high, rocky plateau about half a mile back from the edge of the river canyon. Stern, in his eagerness, was all for cave-hunting that very evening, but the girl restrained him.

"Not so impatient, dear!" she cautioned. "'Too fast arrives as tardy as too slow!' To-morrow's time enough."

"Ruling me with quotations from Shakespeare, eh?" he laughed, with a kiss. "All right, have your way--_Mrs._ Stern!"

She laughed, too, at this, the first time she had heard her new name.

So they made camp and postponed further labors till daylight again.

Morning found them early astir and at work. Together they traversed the tropic-seeming woods, aflame with brilliant flowers, dank with ferns and laced with twining lianas.

In the treetops--strange trees, fruit laden--parrakeets and flashing green and crimson birds of paradise disturbed the little monkey-folk that chattered at the intruders. Once a coral-red snake whipped away, hissing, but not quick enough to dodge a ball from Stern's revolver.

Stern viewed the ugly, triangular head with apprehension. Well he knew that venom dwelt there, but he said nothing. The one and only chance of successfully transplanting the Folk must be to regions warm as these. All dangers must be braved a time till they could grow acclimated to the upper air. After that--but the vastness of the future deterred even speculation. Perils were inevitable. The more there were to overcome the greater the victory.

"On to the cliffs!" said he, clasping the girl's hand in his own and making a path for her.

Thus presently they reached the edge of the canyon.

"Magnificent!" cried Beatrice as they came out on the overhang of the rock wall. "With these fruitful woods behind, that river in front, and these natural fortifications for our home, what more could we want?"

"Nothing except caves," Stern answered. "Let's call this New Hope River, eh? And the cliffs?"

"Settlement Cliffs!" she exclaimed.

"Done! Well, now let's see."

For the better part of the morning they explored the face of the palisade. Its height, they estimated, ranged from two to three hundred feet, shelving down in rough terraces to the rocky debris through and beyond which foamed the strong current of New Hope River, a stream averaging about two hundred yards in width.

Up-current a broader pool gave promise of excellent fishing. It overflowed into violent rapids, with swift, white waters noisily cascading.

"There, incidentally," Stern remarked, with the practical perception of the engineer, "there's power enough, when properly harnessed, to light a city and to turn machinery ad libitum. I don't see how we could better this site, do you?"

"Not if you think there are good chances for cave-dwellings," she made answer.

"From what we've seen already, it looks promising. Of course, there'll be a deal of work to do; but there are excellent possibilities here.

First rate."

Fortune seemed bent on favoring them. The limestone cliff, fantastically eroded, offered a score of shelters, some shallow and needing to be walled up in front, others deep and tortuous. All was in utter confusion.

Stern saw that the terraces would have to be blasted and leveled, roads and stairs built along the face of the rock and down to the river, stalact.i.tes and stalagmites cut away, chambers fashioned, and a vast deal of labor done; but the rough framework of a cliff colony undeniably existed here. He doubted whether it would be possible to find a more favorable site without long and tedious travels.

"I guess we'll take the apartments and sign the lease," he decided toward noon, after they had clambered, pried, explored with improvised torches, and penetrated far into some of the grottoes. "The main thing to consider is that we can find darkness and humidity for the Folk by day. They mustn't be let out at first except in the night. It may be weeks or months before they can stand the direct sunlight. But that, too, will come. Patience, girl--patience and time--and all will yet be done."

Yet, even as he spoke, a strange anxiety, a prescience of tremendous difficulties, brooded in his soul. These were not cattle that he had to deal with, but _men_.

Could he and Beatrice, rulers of the Folk though they now were, could they--with their paltry knowledge of the people's language, superst.i.tions, prejudices and inner life--really bring about this great migration?

Could they ravish a nation from its accustomed home, transplant it bodily, force new conditions on it, train, teach, civilize it? All this without rebellion, anarchy and failure?

"G.o.d!" thought the engineer. "The labors of Hercules were child's play beside this problem!"

His heart quaked at the thought of all that lay ahead; yet through everything, deep in the basic strata of his being, he knew that all should be and must be as he planned.

Barring death only, the seemingly impossible should come to pa.s.s.

"I swear it!" he murmured to himself. "For _her_ sake, for theirs, and for the world's, I swear it shall be!"

At high noon they emerged once more from the caverns, climbed the steep cliff face, and again stood on the heights.

Facing northward, their gaze swept the lower river-bank opposite, and reached away, away, over the rolling hills and plains that lay, a virgin forest, to the dim horizon, brooding, mysterious, quivering with fertility and wild, strange life.

"Some time," he prophesied, sweeping his arm out toward the wilderness--"some time all _that_--and far beyond--shall be dotted with clearings and rich farms, with cottages, schools, towns, cities.

Broad highways shall traverse it. The hum of motors, of machinery, of industry--of life itself--shall one day displace the cry of beast and bird.

"Some time the English tongue shall reign here again--here and beyond.

Here strong men shall toil and build and reap and rest. Here love shall reign and women be called 'mother.' Here children shall play and learn and grow to manhood and to womanhood, secure and free.

"Some time all good things shall here come to realization. Oppression and slavery, alone, shall be undreamed of. These, and poverty and pain, shall never enter into the new world that is to be.

"Some time, here, 'all shall be better than well.' _Some time!_"

He circled her with his arm, and for a while they stood surveying this cradle of the new race. Much moved, Beatrice drew very close to him.

They made no speech.

For the dreams they two were dreaming, as the golden sun irradiated all that vast, magnificent wilderness, pa.s.sed any power of words.

Only she whispered "Some time!" too, and Allan knew she shared with him the glory of his vast, tremendous vision!
