of this meat with us. There is no telling when we will be able to get more."
And so the two set out down the river toward the south. The man carried the short spear that Tarzan had left with the girl, while she was entirely unarmed except for a stick she had picked up from among those left after the building of the hut. Before departing she had insisted that the man leave a note for Tarzan thanking him for his care of them and bidding him goodbye. This they left pinned to the inside wall of the hut with a little sliver of wood.
It was necessary that they be constantly on the alert since they never knew what might confront them at the next turn of the winding jungle trail or what might lie concealed in the tangled bushes at either side. There was also the ever-present danger of meeting some of Numabo's black warriors and as the village lay directly in their line of march, there was the necessity for making a wide detour before they reached it in order to pass around it without being discovered.
"I am not so much afraid of the native blacks," said the girl, "as I am of Usanga and his people. He and his men were all attached to a German native regiment. They brought me along with them when they deserted, either with the intention of holding me ransom or selling me into the harem of one of the black sultans of the north. Usanga is much more to be feared than Numabo for he has had the advantage of European military training and is armed with more or less modern weapons and ammunition."
"It is lucky for me," remarked the Englishman, "that it was the ignorant Numabo who discovered and captured me rather than the worldly wise Usanga. He would have felt less fear of the giant flying machine and would have known only too well how to wreck it."
"Let us pray that the black sergeant has not discovered it," said the girl.
They made their way to a point which they guessed was about a mile above the village, then they turned into the trackless tangle of undergrowth to the east. So dense was the verdure at many points that it was with the utmost difficulty they wormed their way through, sometimes on hands and knees and again by clambering over numerous fallen tree trunks. Interwoven with dead limbs and living branches were the tough and ropelike creepers which formed a tangled network across their path.
South of them in an open meadowland a number of black warriors were gathered about an object which elicited much wondering comment. The blacks were clothed in fragments of what had once been uniforms of a native German command. They were a most unlovely band and chief among them in authority and repulsiveness was the black sergeant Usanga. The object of their interest was a British aeroplane.
Immediately after the Englishman had been brought to Numabo's village Usanga had gone out in search of the plane, prompted partially by curiosity and partially by an intention to destroy it, but when he had found it, some new thought had deterred him from carrying out his design. The thing represented considerable value as he well knew and it had occurred to him that in some way he might turn his prize to profit. Every day he had returned to it, and while at first it had filled him with considerable awe, he eventually came to look upon it with the accustomed eye of a proprietor, so that he now clambered into the fuselage and even advanced so far as to wish that he might learn to operate it.
What a feat it would be indeed to fly like a bird far above the highest tree top! How it would fill his less favored companions with awe and admiration! If Usanga could but fly, so great would be the respect of all the tribesmen throughout the scattered villages of the great interior, they would look upon him as little less than a god.
Usanga rubbed his palms together and smacked his thick lips. Then indeed, would he be very rich, for all the villages would pay tribute to him and he could even have as many as a dozen wives. With that thought, however, came a mental picture of Naratu, the black termagant, who ruled him with an iron hand. Usanga made a wry face and tried to forget the extra dozen wives, but the lure of the idea remained and appealed so strongly to him that he presently found himself reasoning most logically that a god would not be much of a god with less than twenty-four wives.
He fingered the instruments and the control, half hoping and half fearing that he would alight upon the combination that would put the machine in flight. Often had he watched the British air-men soaring above the German lines and it looked so simple he was quite sure that he could do it himself if there was somebody who could but once show him how. There was, of course, always the hope that the white man who came in the machine and who had escaped from Numabo's village might fall into Usanga's hands and then indeed would he be able to learn how to fly. It was in this hope that Usanga spent so much time in the vicinity of the plane, reasoning as he did that eventually the white man would return in search of it.
And at last he was rewarded, for upon this very day after he had quit the machine and entered the jungle with his warriors, he heard voices to the north and when he and his men had hidden in the dense foliage upon either side of the trail, Usanga was presently filled with elation by the appearance of the British officer and the white girl whom the black sergeant had coveted and who had escaped him.
The Negro could scarce restrain a shout of elation, for he had not hoped that fate would be so kind as to throw these two whom he most desired into his power at the same time.
As the two came down the trail all unconscious of impending danger, the man was explaining that they must be very close to the point at which the plane had landed. Their entire attention was centered on the trail directly ahead of them, as they momentarily expected it to break into the meadowland where they were sure they would see the plane that would spell life and liberty for them.
The trail was broad, and they were walking side by side so that at a sharp turn the park-like clearing was revealed to them simultaneously with the outlines of the machine they sought.
Exclamations of relief and delight broke from their lips, and at the same instant Usanga and his black warriors rose from the bushes all about them.
Chapter XII The Black Flier
The girl was almost crushed by terror and disappointment. To have been thus close to safety and then to have all hope snatched away by a cruel stroke of fate seemed unendurable. The man was disappointed, too, but more was he angry. He noted the remnants of the uniforms upon the blacks and immediately he demanded to know where were their officers.
"They cannot understand you," said the girl and so in the bastard tongue that is the medium of communication between the Germans and the blacks of their colony, she repeated the white man's question.
Usanga grinned. "You know where they are, white woman," he replied. "They are dead, and if this white man does not do as I tell him, he, too, will be dead."
"What do you want of him?" asked the girl.
"I want him to teach me how to fly like a bird," replied Usanga.
Bertha Kircher looked her astonishment, but repeated the demand to the lieutenant.
The Englishman meditated for a moment. "He wants to learn to fly, does he?" he repeated. "Ask him if he will give us our freedom if I teach him to fly."
The girl put the question to Usanga, who, degraded, cunning, and entirely unprincipled, was always perfectly willing to promise anything whether he had any intentions of fulfilling his promises or not, and so immediately assented to the proposition.
"Let the white man teach me to fly," he said, "and I will take you back close to the settlements of your people, but in return for this I shall keep the great bird," and he waved a black hand in the direction of the aeroplane.
When Bertha Kircher had repeated Usanga's proposition to the aviator, the latter shrugged his shoulders and with a wry face finally agreed. "I fancy there is no other way out of it," he said. "In any event the plane is lost to the British government. If I refuse the black scoundrel's request, there is no doubt but what he will make short work of me with the result that the machine will lie here until it rots. If I accept his offer it will at least be the means of assuring your safe return to civilization and that" he added, "is worth more to me than all the planes in the British Air Service."
The girl cast a quick glance at him. These were the first words he had addressed to her that might indicate that his sentiments toward her were more than those of a companion in distress. She regretted that he had spoken as he had and he, too, regretted it almost instantly
