Less than three weeks after the extermination of the Horde, Stern had already completed important measures looking toward the rehabilitation of the colony.

The damage had been largely repaired. Now only some half-dozen convalescent cases still remained on the sick-list. What the colony had lost in numbers it had gained in solidarity and a truer loyalty than ever before felt there.

All the survivors, now vastly more faithful to the common cause than in the beginning, showed an eager longing to lay hold of the impending problems with Stern, and to labor faithfully for the future of the great undertaking.

The fishing, hunting and domestication of wild animals all were resumed, and again the sound of hammers and anvils clanked through the caves.

Under Stern's direction, half a dozen men crossed the pools in boats, descended the north bank of the river, and got hold of the cut bridge cables.

Stern shot a thin line over to them by means of a bow and arrow. With this they pulled a stouter cord across, and finally a strong cable.

All hands together soon brought the bridge once more up the cliff, where it was lashed to its old moorings.

Barring a few broken floor-planks, easily replaced, only slight damage had been done. One day's labor sufficed to put it in repair again.

The parapet was rebuilt and a wall constructed across the end of the broken terrace. Work was begun on new cave dwellings, with great care not to weaken the strata and so invite another disaster.

Stern, very wise by now in gauging the barbarian mentality, undertook no direct punishment of such as had been led away by H'yemba. But he gathered all the Folk together in the palisade, and there--close to the mutely eloquent object-lesson of the little cemetery--he made them a charweg, a talk in their own speech.

"My people!" cried he, erect and strong before them all, "listen now, for this thing ye must know!

"The evil of your hearts, thinking to prevail against me and the Law, hath brought ye misery and death! Ye have rebelled against the Law, and behold, many are now dead--innocent as well as guilty. The landslide smote ye, and enemies came enemies far more terrible than the dreaded Lanskaarn ye fought in the Abyss! But a little more and ye had all died with battle and disaster. Only my hand alone saved ye--all who still live to breathe this upper air.

"Men! Ye beheld my doing with the earthquake and the Horde! Ye beheld, too, my answer to H'yemba, the evil man, the rebel and traitor. Him ye saw hurled, bleeding, from the parapet! That was my answer to his insolence! And if not he, then who can ever stand against me?"

He paused, and swept them with his glance, letting the lesson sink deep home. Before him their eyes were lowered; their heads bowed; and through them all ran murmurs of fear and supplication.

"My Folk! Rightly might I be angered with you, and require sacrifice and still more blood; but I am merciful. I shall not punish; I shall only teach, and guide, and help! For my heart is your heart, and ye are precious in my eyes.

"But, hark ye now, and think, and judge for yourselves! If any ever speak again of rebellion, or of treason, and seek to break the Law, on his head shall be the blood of all. For surely woe shall come again on us. In your own behalf I warn you, and ye shall be the judges. Now answer me, O my Folk, what shall be done unto any who rebels?"

"He shall die!" boomed the voice of Zangamon. The loyal fighter, now lean and gaunt with great labors, but still powerful, raised his corded hand on high. "Of a truth, that man shall die!"

"What death?" cried Stern.

"Even the death of H'yemba! Let him be cast from the parapet to death in the white rushing river far below!"

All echoed the cry: "Death to all traitors, from the rock!"

"So be it, then," Stern concluded. "Ye have spoken, and it shall be written as a Law. From Execution Rock shall all conspirators be cast.

Now go!"

He dismissed them. While they departed and filed down the terraces to their own homes, he stood there with folded arms, watching them very gravely. The last one vanished. He nodded.

"They'll do now!" said he to himself. "No more trouble from that source! Another milestone pa.s.sed along the road of self-control, self-government and communal spirit. Ah, but the road's a long one yet--a long and hard and stony road to follow!"

Next day Stern began making his plans for the recovery of the lost aeroplane.

"This is by far the most important matter now before the colony," he told Beatrice, watching her nurse the boy as they sat by the fire, while outside the rain drummed over cliff and canyon, hill and plain.

"Our very life depends on keeping a free means of communication open with the mother-country of the Folk, so to call it, and with the city-ruins that supply us with so many necessary articles. No other form of transportation will do. At all hazards we _must_ have an aeroplane--one at least, more later, if possible."

"Of course," she answered; "but why not make one here? Down there in your workshop--"

"I haven't the equipment yet," he interrupted; "nor yet the necessary metal, the wire, a hundred things. All that will come in time when we get some mines to work and start a few blast-furnaces. But for the present, the best and quickest thing to do will be to look up the old machine again."

"But," she objected, terrified at thought of losing him again: "but I thought you said the Horde wrecked it!"

"So they did; but beasts like that probably couldn't destroy the vital mechanism beyond possibility of repair. That is, not unless they heaped a lot of wood all over it, and heated it white-hot, which I don't think they had intelligence enough to do. In any event, what's left will serve me as a model, for another machine. I really think I'll have to have a try for it."

"Oh, Allan! You aren't going to venture out into the wilderness again?"

"Why not, dearest? You must remember the forest is all burned now; perhaps for hundreds of miles. And the Horde, the one greatest peril that has dogged us ever since those days in the tower, has been swept out with the besom of flame!"

"Which has also surely destroyed the machine, even if _they_ haven't!"

she exclaimed, using every possible argument to discourage him.

"I hardly think so," he judged. "You see, I left it in a wide sand-barren. I think, on the whole, it will pay me to make the expedition. Of course I shan't take less than a dozen men to help me bring it back--what's left of it."

"But Allan, can you find your way?"

"I've got to! That machine must positively be recovered! Otherwise we're totally cut off from the Abyss. Colonizing stops, and all kinds of h.e.l.l may break loose below ground before I can build another machine entire. There are no railroads running now to the brink," he added smiling; "and no elevators to the bas.e.m.e.nt of the world. It's the old Pauillac again or nothing!"

The girl exhausted all her arguments and entreaties in vain. Once Allan's mind was definitely made up along the line of duty, he went straight forward, though the heavens fell.

Four days later the expedition set out.

Allan had made adequate preparations in every way. He left a strong and well-armed guard to protect Settlement Cliffs. By careful thought and chart-drawing he was able to approximate the probable position of the machine. With him he took fifteen men, headed by Zangamon, who now insisted he was well enough to go, and ably seconded by Frumuos.

Each man carried an automatic, and six had rifles. They bore an average of one hundred cartridges apiece, and in knapsacks of goat-leather, dried rations for a week. Each also carried fish hooks and a stout fiber line.

The party counted on being able to supplement their supplies with trout, ba.s.s and pickerel from countless untouched streams. They might, too, come into wooded country, if the fire had left any to northward, and here they knew game would be plentiful.

One thing seemed positive in that new world: starvation could not threaten.

Cloudy and dull the morning was--yet well-suited to the needs of the Folk--when the expedition left Settlement Cliffs. The convoy, each man provided with eye-guards and his hands and face well painted with protecting pigment, waited impatiently in the palisade, while Allan said farewell to Beta and the little chap.

For a long moment he strained them both to his breast, then, the woman's kiss still hot upon his lips, ran quickly up the path and joined his picked troop of scouts.

"Forward, men!" cried he, taking the lead with Zangamon.

Some minutes later Beatrice saw them defiling over the long, shaking bridge.

Through her tears she watched them, waving her hand to Allan--even making the baby shake its little hand as well--and throwing kisses to him, who returned them gaily.

On the far bank the party halted a minute to shout a few last words to the a.s.sembled colonists that lined the parapet of the terrace.

Then they turned, and, striking northwest, plunged boldly into the burned and blackened waste.

Long after the marching column had disappeared over the crest of the second hill Beatrice still watched. Up on the cliff-top, with the powerful telescope at her eye, she followed the faint, drifting line of dust and ash that marked the line of march.
