Only his lips smiled as he spoke.

That same night Leon Stabutch left Moscow. He thought that he left secretly and alone, but Fate was at his side in the compartment of the railway carriage.

As Lady Barbara Collis bailed out in the clouds above the Ghenzi range, and Lafayette Smith trod the gangplank leading aboard the liner, and Stabutch stood before Stalin, Tarzan, with knitted brows, looked down upon the black kneeling at his feet.

"Rise!" he commanded, and then; "Who are you and why have you sought Tarzan of the Apes?"

"I am Kabariga, O Great Bwana," replied the black. "I am chief of the Bangalo people of Bungalo. I come to the Great Bwana because my people suffer much sorrow and great fear and our neighbors, who are related to the Gallas, have told us that you are the friend of those who suffer wrongs at the hands of bad men."

"And what wrongs have your people suffered?" demanded Tarzan, "and at whose hands?"

"For long we lived at peace with all men," explained Kabariga; "we did not make war upon our neighbors. We wished only to plant and harvest in security. But one day there came into our country from Abyssima a band of shiftas who had been driven from their own country. They raided some of our villages, stealing our grain, our goats and our people, and these they sold into slavery in far countries.

"They do not take everything, they destroy nothing; but they do not go away out of our country. They remain in a village they have built in inaccessible mountains, and when they need more provisions or slaves they come again to other villages of my people.

"And so they permit us to live and plant and harvest that they may continue to take toll of us."

"But why do you come to me?" demanded the ape-man. "I do not interfere among tribes beyond the boundaries of my own country, unless they commit some depredation against my own people."

"I come to you, Great Bwana," replied the black chief, "because you are a white man and these shiftas are led by a white man. It is known among all men that you are the enemy of bad white men."

"That," said Tarzan, "is different. I will return with you to your country."

And thus Fate, enlisting the services of the black chief, Kabariga, led Tarzan of the Apes out of his own country, toward the north. Nor did many of his own people know whither he had gone nor why--not even little Nkima, the close friend and confidant of the ape-man.

Chapter 2. The Land of Midian

Abraham, the son of Abraham, stood at the foot of the towering cliff that is the wall of the mighty crater of a long extinct volcano. Behind and above him were the dwellings of his people, carved from the soft volcanic ash that rose from the bottom of the crater part way up the encircling cliffs; and clustered about hini were the men and women and children of his tribe.

One and all, they stood with faces raised toward the heavens, upon each countenance reflected the particular emotion that the occasion evoked--wonder, questioning, fear, and always rapt, tense listening, for from the low clouds hanging but a few hundred feet above the rim of the great crater, the floor of which stretched away for fully five miles to its opposite side, came a strange, ominous droning sound, the like of which not one of them had ever heard before.

The sound grew in volume until it seemed to hover just above them, filling all the heavens with its terrifying threat; and then it diminished gradually until it was only a suggestion of a sound that might have been no more than a persistent memory rumbling in their heads; and when they thought that it had gone it grew again in volume until once more it thundered down upon them where they stood in terror or in ecstasy, as each interpreted the significance of the phenomenon.

And upon the opposite side of the crater a similar group, actuated by identical fears and questionings, clustered about Elija, the son of Noah.

In the first group a woman turned to Abraham, the son of Abraham. "What is it, Father?" she asked. "I am afraid."

"Those who trust in the Lord," replied the man, "know no fear. You have revealed the wickedness of your heresy, woman."

The face of the questioner blenched and now, indeed, did she tremble. "Oh, Father, you know that I am no heretic!" she cried piteously.

"Silence, Martha!" commanded Abraham. "Perhaps this is the Lord Himself, come again to earth as was prophesied in the days of Paul, to judge us all." His voice was high and shrill, and he trembled as he spoke.

A half grown child, upon the outskirts of the assemblage, fell to the ground, where he writhed, foaming at the mouth. A woman screamed and fainted.

"Oh, Lord, if it is indeed Thee, Thy chosen people await to receive Thy blessing and Thy commands," prayed Abraham; "but," he added, "if it is not Thee, we beseech that Thou savest us whole from harm."

"Perhaps it is Gabriel!" suggested another of the long bearded men.

"And the sound of his trump," wailed a woman--"the trump of doom!"

"Silence!" shrilled Abraham, and the woman shrank back in fear.

Unnoticed, the youth floundered and gasped for breath as, with eyes set as in death, he struggled in the throes of agony; and then another lurched and fell and he, too, writhed and foamed.

And now they were dropping on all sides--some in convulsions and others in deathlike faints--until a dozen or more sprawled upon the ground, where their pitiable condition elicited no attention from their fellows unless a stricken one chanced to fall against a neighbor or upon his feet, in which case the latter merely stepped aside without vouchsafing so much as a glance at the poor unfortunate.

With few exceptions those who suffered the violent strokes were men and boys, while it was the women who merely fainted; but whether man, woman or child, whether writhing in convulsions or lying quietly in coma, no one paid the slightest attention to any of them. As to whether this seeming indifference was customary, or merely induced by the excitement and apprehension of the moment, as they stood with eyes, ears, and minds focussed on the clouds above them, only a closer acquaintance with these strange people may enlighten us.

Once more the terrifying sound, swollen to hideous proportions, swept toward them; it seemed to stop above them for a moment and then--

Out of the clouds floated a strange apparition--a terrifying thing--a great, white thing above, below which there swung to and fro a tiny figure. At sight of it, dropping gently toward them, a dozen of the watchers collapsed, frothing, in convulsions.

Abraham, the son of Abraham, dropped to his knees, raising his hands in supplication toward the heavens. His people, those of them who were still upon their feet, followed his example. From his lips issued a torrent of strange sounds--a prayer perhaps, but if so not in the same language as that in which he had previously spoken to his people nor in any language known to man, and as he prayed, his followers knelt in terrified silence.

Closer and closer floated the mysterious apparition until, at length, expectant eyes recognized in the figure floating beneath the small, white cloud the outlines of a human form.

A great cry arose as recognition spread--a cry that was a mingling of terror born wail and ecstatic hosanna. Abraham was among the last to recognize the form of the dangling figure for what it was, or, perhaps, among the last to admit the testimony of his eyes. When he did he toppled to the ground, his muscles twitching and jerking his whole body into horrid contortions, his eyes rolled upward and set as in death, his breath expelled in painful gasps between lips flecked with foam.

Abraham, the son of Abraham, never an Adonis, was at this moment anything but a pretty sight; but no one seemed to notice him any more than they had the score or more of lesser creatures who had succumbed to the nervous excitation of the experiences of the past half hour.

Some five hundred people, men, women and children, of which thirty, perhaps, lay quietly or writhed in convulsions upon the ground, formed the group of watchers toward which Lady Barbara Collis gently floated. As she landed in, if the truth must be told (and we historians are proverbially truthful, except when we are chronicling the lives of our national heroes, or living rulers within whose grasp we may be, or of enemy peoples with whom our country has been at war, and upon other occasions)--but, as I was recording, as Lady Barbara landed in an awkward sprawl within a hundred yards of the assemblage all those who had remained standing up to this time went down upon their knees.

Hastily scrambling to her feet, the girl disengaged the harness of her parachute and stood gazing in perplexity upon the scene about her. A quick glance had revealed the towering cliffs that formed the encircling walls of the gigantic crater, though at the time she did not suspect the true nature of the valley spreading before her. It was the people who claimed her surprised attention.

They were white! In the heart of Africa she had landed in the midst of a settlement of whites. But this thought did not wholly reassure her.
