They were quite close by now, and Dick saw them both start back. Then, as they caught sight of the spluttering devil and took in the situation, he saw them turn to run.

“A mine! A mine!” shouted the half-caste.

Leaping to his feet, he ran towards the gate of the stockade, the native abreast of him, and close on their heels came Dick, aglow with excitement. He was bent on escape. He felt the doors of retreat closing on him, and he was determined to get away. Suddenly James Langdon turned and gripped the native. Then he swung round, as if a thought had occurred to him, and he had realised that there was time yet to save an explosion. Indeed, that was his thought, and he at once ran back to the stockade. An instant later he saw Dick’s figure bounding towards him in the darkness. He gave vent to a shout, and then crashed up against a boulder which happened to lie there, for our hero’s fist had struck him full on the chest. The blow almost staggered Dick, too, but he recovered his balance in a moment, and, swinging round, dealt the native a fierce stroke on the chin, sending him reeling. After that he was off like lightning. He was out of the gate ere a second had passed, and, darting round the stockade, was soon clambering up to the crest. Nor did he halt till he had reached the summit.

“Rest a moment,” said the voice of the chief. “I heard the commotion, and I am glad to report that the men who followed you into the place fled down the hill. See the smoke coming from the hut. And there are the flames. We will move when you are ready.”

Some five minutes later the two set off for the forest, the native leading, for he knew the way well, and had this enormous advantage over his young English leader, that he could see on such a night so well that they never once found themselves in a part where the difficulties of the track baulked their further progress. Since the day on which the expedition had first arrived, Dick had often taken the short cut to the forest which the agent had then used, and he knew how steep and difficult it was in parts, and how much care it called for, even when the easiest descents were selected. Had he had to find his way down alone on this night, he would probably have broken a limb, or lost his foothold and rolled, certainly to be dashed senseless before he reached the bottom. Then, too, it was not a time for hurry, such a dark night as this. But they had no choice. They could already see the glare of the flaming stockade in the sky. They could hear the shouts of their enemies, and they knew, the native far better than did Dick, that already his countrymen would be on the track.

“Once in the forest we shall be safe, I think,” he said, speaking as easily as if he had made no unusual efforts, though our hero was so short of breath that he gasped.

“Then we will put out all our strength to reach that place.”

By now they were near the foot of the rocky hill, and presently they were running steadily across the level. At length they reached the edge of the forest, where they halted, Dick to throw himself on the ground and gasp there for breath.

“A fine bonfire for our enemies,” laughed the chief, exulting now that he had left the worst of the danger behind. “How is it that there is no explosion?”

No explosion! The bomb had failed! Dick looked up suddenly, his fatigue forgotten in an instant.
