But Jack was too weary and low-spirited to reply to his companion's jokes, and he lay back after a time, watching the soft glow over the volcano far above their heads, then the brilliant stars, which looked larger than at home, and glided suddenly into a deep sleep, from which he was awakened by a rough prod from the butt end of a spear. The lad flushed angrily, but tried to curb his resentment, and turned away as he rose, to find Ned standing watching him in the early morning light. "Never mind, Mr Jack," he said softly. "It's hard to bear; but this isn't the time to show fight. That black brute kicked me to wake me, and it made me as savage as a bear. If he'd had boots on I should have hit him, I know I should, I couldn't have helped it even if he'd killed me for it; but then you see he hadn't boots on, though the sole of his foot's almost like hoof." "They're going on directly, Ned." "Are they, sir? Well, I must have a drink of water first." He took a step toward the pool; but a spear was presented at his breast, and it was not until Jack had made a sign of drinking that they were allowed to bend down over it. Directly after they started back up the side gorge to where it joined the greater, and then began to descend again by what proved to be a very precipitous but direct way down toward the sea, water soon after making its appearance in a mere thread, which suddenly leaped down from a crack in the side and found its way to the bottom: while as they were hurried on by their more nimble captors, the stream kept on increasing in volume by the help of the many tiny tributaries which joined it. Under different auspices the walk would have been glorious. Sir John and the doctor would have found it one grand preserve for birds and insects; but the prisoners had hard work to keep up with their sure-footed captors, and any hesitation on arriving at a difficult bit of the descent was looked upon as an attempt to escape. The blacks were evidently quite at home in this one of the many ravines which carried the water condensed upon the mountain down to the sea, and consequently made pretty good speed; but this came hard upon their prisoners, who occupied so much time in descending the worst parts that they became at last menacing, and Jack trembled for the consequences of Ned retaliating with a blow. "It would do no good, Ned," he said earnestly. "But it makes us seem so cowardly to let them poke at us with their spears, sir, and never do anything." "Never mind how it seems, Ned. You are not cowardly." "Well, I'd punch any fellow's head who said I was, sir, or who said the same about you." "They can't say it so that we can understand, and let them think what they like. We'd fight if there was anything to be got by it; but there isn't, Ned. Let's pretend to be beaten now, and then they will not be so watchful. To-night they will sleep somewhere down near the shore, and we may get a chance to escape."
