And then a voice called in the blackness, and he ploughed toward it, and it called again, and again, and at last he struck a match with trembling fingers and saw her, dangling as he had dangled, some fifteen feet from the ground. She smiled waveringly, with a little gasp of relief, and he heard something go slithering away, very furtively.
She clung to him desperately when he had gotten her down to solid earth. But he was savage.
"Those shots—though I'm glad you fired them—may have been a tip-off to the town. We've got to keep moving, Paula."
Her breath was coming quickly.
"They could trail us, Charles. By daylight we might not leave signs, but forcing our way through the night...."
"Right, as usual," admitted Bell. "How about shells? Did you use all you had?"
"Nearly. But I was afraid, Charles."
Bell felt in his pockets. Half a box. Perhaps twenty-five shells. With the town nearby and almost certainly having heard their signals to each other. Black rage invaded Bell. They would be hunted for, of course. Dogs, perhaps, would trail them. And the thing would end when they were at bay, ringed about by The Master's slaves, with twenty-five shells only to expend.
The dim little glow in the sky between the jungle leaves kept up. It was bright, and slowly growing brighter. There was a sudden flickering and even the jungle grew light for an instant. A few seconds later there was a heavy concussion.
"Something else went up then," growled Bell. "It's some satisfaction, anyway, to know I did a lot of damage."
And then, quite abruptly, there was an obscure murmuring sound. It grew stronger, and stronger still. If Bell had been aloft, he would have seen the planes from The Master's hangars being rushed out of their shelters. One of the long row of buildings had caught. And the plateau of Cuyaba is very, very far from civilization. Tools, and even dynamos and engines, could be brought toilsomely to it, but the task would be terrific. Buildings would be made from materials on the spot, even the shelters for the planes. It would be much more practical to carry the parts for a saw mill and saw out the lumber on the spot than to attempt to freight roofing materials and the like to Cuyaba. So that the structures Bell had seen in the wing lights' glow were of wood, and inflammable. The powerhouse that lighted the landing field was already ablaze. The smaller shacks of the laborers perhaps would not be burnt down, but the elaborate depot for communication by plane and wireless was rapidly being destroyed. The reserve of gasoline had gone up in smoke almost at the beginning, and in spreading out had extended the disaster to nearly all the compact nerve-center of the whole conspiracy.
Presently the droning noise was tumultuous. Every plane in a condition to fly was out on the landing field, now brightly lighted by the burning buildings all about. There was frantic, hectic activity everywhere. The secretaries of The Master were rescuing what records they could, and growing cold with terror. In the confusion of spreading flames and the noise of roaring conflagrations the stopping of the motor up aloft had passed unnoticed. In the headquarters of The Master there was panic. An attack had been made upon The Master. A person who could not be one of his slaves had found his stronghold and attacked it terribly. And if one man knew that location and dared attack it, then....
The hold of The Master upon all his slaves was based on one fact and its corollary. The fact was, that those who had been given his poison would go murder mad without its antidote. The corollary was that those who obeyed him would be given that antidote and be safe. True, the antidote was but a temporary one, and mixed with it for administration was a further dosage of the poison itself. But the whole power of The Master was based on his slaves' belief that as long as they obeyed him abjectly there would be no failure of the antidote's supply. And Bell had given that belief a sudden and horrible shock.
Orders came from one frightened man, who cursed much more from terror than from rage. Ribiera had advised him. To do him justice, Ribiera felt less fear than most. Nephew to The Master, and destined successor to The Master's power, Ribiera dared not revolt, but at least he had little fear of punishment for incompetence. It was his advice that set the many aircraft motors warming up. It was his direction that assorted out the brainwork staff. And Ribiera himself curtly took control, indifferently abandoned the enslaved workers to the madness that would come upon them, and took wing in the last of a stream of roaring things that swept upward above the smoke and flame and vanished in the sky.
Bell and Paula were huddled in between the buttress roots of a jungle giant, protected on three sides by the monster uprearings of solid wood, and Bell was absorbedly feeding a tiny smudge fire. The smoke was thick and choking, but it did keep off the plague of insects which make jungle travel much less than the romantic adventure it is pictured. Bell heard the heavy, thunderous buzzing from the town change timbre suddenly. A single note of it grew loud and soared overhead.
He stared up instinctively, but saw nothing but leaves and branches and many climbing things above him, dimly lighted by the smoky little blaze. The roaring overhead went on, and dimmed. A second roaring came from the town and rose to a monstrous growling and diminished. A third did likewise, and a fourth.
At stated, even intervals the planes at headquarters of The Master took off from the landing field, ringed about with blazing buildings, and plunged through the darkness in a straight line. The steadier droning from the town grew lighter as the jungles echoed for many miles with the sounds of aircraft motors overhead.
At last a single plane rose upward and thundered over the jungle roof. It went away, and away.... The town was silent, then, and only a faint and dwindling murmur came from the line of aircraft headed south.
"They've deserted the town, by God!" said Bell, his eyes gleaming. "Scared off!"
"And—and we—" said Paula, gazing at him.
"You can bet that every man who could crowd into a plane did so," said Bell grimly. "Those that couldn't, if they have any brains, will be trying to make it some other way to where they can subject themselves to one of The Master's deputies and have a little longer time of sanity. The poor devils that are left—well—they'll be camaradas, peons, laborers, without the intelligence to know what they can do. They'll wait patiently for their masters to come back. And presently their hands will writhe.... And the town will be a hell."
"Then they won't be looking for us?"
Bell considered. And suddenly he laughed.
"If the fire has burned out before dawn," he said coldly, "I'll go looking for them. It's going to be cold-blooded, and it's going to be rather pitiful, I think, but there's nothing else to do. You try to get some rest. You'll need it."
And for all the rest of the dark hours he crouched in the little angle formed by the roots of the forest giant, and kept a thickly smoking little fire going, and listened to the noises of the jungle all about him.
It was more than a mile back to the town. It was nearer two. But it was vastly less difficult to force a way through the thick growths by daylight, even though then it was not easy. With machetes, of course, Bell and Paula would have had no trouble, but theirs had been left in the plane. Bell made a huge club and battered openings by sheer strength where it was necessary. Sweat streamed down his face before he had covered five hundred yards, but then something occurred to him and he went more easily. If there were any of the intelligent class of The Master's subjects left in the little settlement, he wanted to allow time enough for them to start their flight. He wanted to find the place empty of all but laborers, who would be accustomed to obey any man who spoke arrogantly and in the manner of a deputy of The Master. Yet he did not want to wait too long. Panic spreads among the camarada class as swiftly as among more intelligent folk, and it is even more blind and hysterical.
