"We'll go and see what it comes from."
Smith scarcely dared to hope that the discovery of the smoke would be of any assistance to him. But it was the first indication of a camp within the forest, whether of the islanders or of his friends, and he could not neglect to investigate it. The aeroplane flew along at the speed of a swallow. In little more than three minutes it reached the twine of smoke. Checking the engine, Smith wheeled the aeroplane round until it passed slowly over an extensive gap in the forest. He looked down. The smoke rose from a fire in the midst of the clearing. At a little distance from it there was a throng of islanders, gazing up awe-struck at the strange apparition whose approach had been heralded from afar, and which now circled above them, making terrifying noises.
But Smith was not interested in the islanders. He peered among them and around for white men. He felt a shock of bitter disappointment; all the upturned faces were brown. But the movement of the aeroplane brought him to the verge of the forest, and then Rodier gave a shout of delight.
"There they are! There they are, mister!" he cried, pointing obliquely downwards.
Smith looked over. In the shade at the foot of the trees he saw a number of men bound each to a trunk. Their faces, directed upwards, were too darkly shadowed for him to distinguish their race; but they were clothed. Beyond doubt they were the castaways.
In a moment he determined what to do. While the aeroplane circled slowly above their heads the islanders would feel no more than awe and wonder. They huddled together like a flock of sheep in a thunderstorm, probably not as yet connecting the aerial visitant with their prisoners. What was required was to scatter them, suddenly, in a way that would smite them with terror, and cause them to flee without thought of the captives helpless against the trees.
Smith sailed away eastward, disappearing from their sight. He had made a quick mental calculation of the extent of the clearing. Rising to the height of about three hundred feet above the ground, while still out of sight he suddenly stopped the engine and warped the planes for a dive. The aeroplane descended rapidly, grazed the tops of the trees, and then, more slowly, swept, silently, in a gentle curve towards the throng of men, who were chattering about the mysterious sky visitor. When they caught sight of it they were struck dumb, and for a few moments seemed to be fixed to the ground with amazement. Then, as it came directly towards them, and Smith set the noisy propellers in motion, they uttered shrieks of dismay and terror, and fled like hares into the forest.
Some of them started too late. Smith, being now near the ground, set the engine going at low speed, overtook a group of the islanders before they reached shelter, and with a touch of the aeroplane flung them violently on their faces. He then wheeled round, and rose once more into the air in order to effect a complete descent. The prostrate natives lay for some time in a paralysis of fear; but finding that they were unhurt, and that the monster had withdrawn from them, they picked themselves up, and ran to overtake their friends, leaving the space clear.
