They went on.

'There again!' said Hoole, a few seconds later. He looked round apprehensively. A slight groan came from Meek.

'What's the matter?' asked Trentham in a whisper, sharply. His nerves were a little on edge.

'I seed a face, sir,' murmured the man, staring into the gloom.

'Nonsense! It's too dark to see anything. We 'll stop in a few minutes, when it's quite dark; but we must get as far as we can from where we saw that native.'

They had not advanced more than a dozen yards when Hoole made a sudden dash among the bushes. The rest halted, drawing quick breaths. He came back after half a minute's absence.

'I distinctly heard a sound there,' he explained. 'No; it's not jumpiness. But I couldn't see any one or anything. I vote we stop, Trentham. We shall lose our bearings utterly if we go too far into the forest, where we can't see the sun to-morrow.'

'I think you 're right. Now to find trees we can climb, and big enough to give us safe perches. Grinson, put down your bag and have a look round.'

The boatswain had just risen from stooping to the ground; the others were standing by, looking up for broad forks which promised security, when with a sudden whish that took them all aback the brushwood around them parted and a score or more of dusky natives burst into the ring. Before they could raise a finger in self-defence they were thrown headlong, and sinewy hands were knotting pliant tendrils about their arms and legs, while others held them down. In a few minutes the binding was finished. The captors collected, and jabbered away among themselves. One of them had opened the bag, and was munching a biscuit. The bag was wrenched from his hands; and the four prisoners, lying on their backs, watched the gleeful savages consume their whole stock of provisions to the last crumb.
