We were safe yet, and I felt quite hopeful as I thought of what an advantage we, as defenders, possessed in the darkness over an attacking party advancing light in hand.

The sight, too, of the superstitious terror of the Indians was cheering, and I again felt assured that should Garcia persevere in his determination to search our part of the cave, he must seek other companions or else come alone.

“Tom,” I said then, gently, “we have been away some time now; creep back to my uncle and tell him quietly that the Indians are in the cave, but at present there is no danger to fear. Ask him, though, to put out the light in case they should come this way.”

Tom made no answer, but crept away directly, leaving me in that thick darkness watching for the return of the enemy, and wondering whether we should succeed in getting safely away.

My heart sank as I thought of our peril, with the cunning of the savage and the European mingled to fight against us; while, as to our position, we could set them, I was sure, at defiance here; but could we escape to the river? I still hoped that they would not penetrate our part, forcing us to take to the raft; and at times I began to wonder whether it would not be better to resist their entrance for the sake of saving the mules, unless we could compel these to swim after the raft.

My reverie was broken by the return of Tom.

“All right, Mas’r Harry,” he said; “they’re in the dark now; but I think Miss Lilla was disappointed because you didn’t go. I’ll keep watch if you’d like to go.”

If I’d like to go! I fought down the desire, though, just as a distant echoing murmur, ever increasing, fell upon our ears, and we knew that the searchers were on their way back.

Another minute, and with their last torch burning dimly they were scrambling down from the rift to the cavern chamber, and then hurrying away as fast as the obscurity would allow.

The hours glided by, and at last it became manifest that there was to be no further search that night, so, with Tom, I cautiously made my way to the mouth of the cavern, to find that the enemy had made their bivouac just by the barrier, a bright fire illumining the broad arch, and ruddying the swarthy faces that clustered round, some standing, some lying about upon the sand, while a couple were evidently sentries and stood motionless a little farther in, gazing towards the interior of the cave.
