Ned did not hesitate, but obeyed at once, and they walked softly on into the darkness ahead, for from apparently close behind them—though the speakers had not yet reached the mouth of the low cavern—there came the confused angry gabble of many voices, and on looking back Ned saw the mouth of the place darkened, and it seemed as if the enemy were about to come in; but some were apparently hesitating, and protesting against its being done.

Ned’s dread of the unseen departed at sight of the seen, and he walked firmly onward, gripping Jack’s hand tightly.

“Come on in, sir,” he whispered; “they’re after us. Let’s get into a dark corner, and let ’em have it with stones—some of these sharp bits.”

Everything seemed to point to the fact that they must either get right into the depths of the cavern and trust to finding a place of concealment, or stand on their defence as Ned suggested, and meet their enemies with stones.

They must have retreated quite fifty yards over the sharp cracking fragments, when the light which shone in upon them from the mouth suddenly ceased, and looking round for the cause, they found that the passage had made a sudden turn, so that they had to go back three or four yards before they could catch sight of the enemy.

That which they saw was enough to startle them, showing as it did the imminence of their danger, and that the blacks were probably coming in search of them, under the belief that they were in hiding. For one, evidently the leader, was in advance, with bow and arrow in hand ready to shoot, and his companions held their spears prepared for action as they came on in a stooping attitude.

“Shall we shoot at ’em?” whispered Ned, feeling now in the presence of danger.

“No. Let’s get a little heap of stones and be ready to throw when they are well in reach.”

“Oh, if I could only use my other arm!” muttered Ned. “Come on then, sir. They can’t see us now. Perhaps there’s a narrower place farther in, and the darker it is the better for us and the worse for them.”

The change in the poor fellow was wonderful. He did not seem like the same. It struck Jack for the moment, but he had something else to think about, and he followed his companion quickly, at the risk of slipping into some precipitous place.
