“Oh, that’s true enough, sir. They would only want time. Hullo, you, what’s the matter? Here’s old Mak seen something. Get your guns ready.”

For the black, who had formed one of the topics of conversation that morning as he walked well ahead of the first waggon as they skirted the edge of the forest—the waggons keeping in the open—kept on making incursions towards where the huge trees spread their boughs, and the country was park-like and grand. And now, to bring forth the driver’s exclamation, the keen-eyed black fellow, who had evidently caught sight of something which had excited his interest, was running swiftly in and out of the bushes more and more towards the great trees, in full chase, throwing up his spear now and then as if to signal his companions to follow.

“What is it he is after?” cried Mark.

“I dunno, sir,” replied Buck, who was standing up now upon the waggon chest and holding on to the tilt so as to follow the movements of their guide. “It’s something to eat; you may take your oath of that.”

The black’s movements had been noted by the doctor and Sir James, who, double gun in hand, had been tramping slowly a little to the left of their line of route, on the look out for anything that might be serviceable to supply their larder, and they followed the example of the two boys and threaded their way in amongst the low growth in answer to the silent appeal made by their guide.

Mark was the first to see that Mak was in pursuit of a little naked black figure that was running and doubling through the bushes like a hare.

Its effort was evidently to find a place of concealment, for three times over it disappeared and the boys thought it was gone; but upon each occasion it was evident that Mak’s eyes were too keen, and they saw him approach cautiously, or creep round some clump of trees, with the result that the little black figure started out again, and finally giving up its efforts to conceal itself plunged right in amongst the close growing trees of the forest which rose up beyond the low growth like a wall.

“Lost,” said Mark sharply. “Mak won’t be able to follow him there.”

But he was wrong, for without a moment’s hesitation their guide dashed into the dark cover, while the boys stopped short on coming up to the spot where he had disappeared.

They looked round, but Sir James and the doctor were out of sight. They found too that they had left the waggons behind.
