"I can't make out where we are, Ned," said Jack at last. "Yes, I can; we have worked round more to the south, and must have done nothing but get farther and farther away from the yacht." "Think so, sir? Let's see; we anchored east side first, then we went round and anchored west, and you say we've been travelling south. Well, I dare say you're right, and that means we must keep to the west again. Why, those black fellows must have taken us out of that little valley and put us in another one. I must say it's rather puzzling, sir. But you lead, and I'll follow, for it's of no use for me to pretend to be able to steer." Jack made no reply, but stood looking downward, seeing nothing of the glorious prospect below, his mind being taken up with thoughts of trying to hit the head of the ravine up which they had travelled, for he knew the difficulties attendant upon going down another, to be led right to the edge of the lagoon, with the puzzle before him of not knowing whether to travel to right or left. "There's that flock of shriekers coming along below there, Mr Jack, sir," said the man, breaking in upon the lad's reverie. "No, it ain't: it's pigs. I can see 'em, sir; there they go. My word, I wish I had a gun, and they came within reach; I'd have a shot at one of 'em, and before long it would be roast pork for breakfast. See 'em, sir? There they go." They were plain enough to see at times, a drove of twenty or so, of all sizes, down to quite small porkers, as they raced along over the open patches, and then disappeared in amongst the trees, to re-appear once more as they made for the denser portions of the forest. "Why, there's one left behind, Ned," said Jack suddenly. "It looks as if it was lame." "Why, it has broken down. Look, sir, how it keeps limping. I say, we must have him. We can't let a chance like that go when we're starving. Keep your eye on the spot, sir, while I try and hit off some mark to know him by." Jack's response, as Ned moved to get into a better position for observation, was to leap upon the man and drag him back into the entrance of the cavern. "What did you do that for, sir?" he cried angrily. "Couldn't you see what was coming?" "No, sir," cried Ned surlily; "could you?" "Go down on hands and knees to that block of stone lying there, and peep over cautiously." Ned obeyed in an ill-used fashion, and dropped down again to crawl back into the cavern. "Oh, I say, Mr Jack, seven or eight of them." "I only saw two." "Quite what I said, sir. They must have been hunting the drove, and speared the one that hung behind. Now, then, they'll be stopping to cook and have another feast. Suppose they come in here to make this their kitchen? Hadn't we better slip out at once and make a run for it?" "Run for it?" cried Jack. "How can we up here, where it is all slow climb? No, we must keep in hiding." "But suppose they choose this place and come here?"
