The lights flashed on roof, and from off the water, which rippled over the bamboos and soaked us through and through; but we pressed slowly and steadily on till we must have been half-way to the vault of the troubled waters, when I whispered to Tom to stop.

We were now in a part where the tunnel widened out to thirty or forty feet, though the roof was not more than a foot above our heads, and remarkable for the streaks of a creamy spar which banded it in every direction.

“Tom,” I said in a whisper, as I glanced round to see that we were alone, “could we do better than this?”

As I spoke I was trying the depth with my bamboo pole, to find that, wherever I reached, there was not more than five feet of water.

“But suppose it’s that shivering sand, and it swallers it up, Mas’r Harry?”

“But it’s hard rock, Tom. Feel,” I whispered.

There was no mistaking the firmness of the bottom; so, carefully marking the spot by a cross which I scored on the roof with my knife, we softly dropped in six golden packages over the side of our little raft, which seemed ready to leap out of the water on being released from its heavy burden.

A soft gentle splash in each case, and then the black waters closed over each package, a pang striking my heart as they disappeared; and I asked myself whether I was wise, now that I had gained the object of my search, to let it go from me again like that. I was roused, though, from my reverie by Tom, who generally had a word of encouragement for me at the blackest times.

“There, Mas’r Harry, that’s covered up well, and it can be easily uncovered again; and I’ll lay my head agin a halfpenny apple, that if we don’t come to fetch that there, nobody else won’t; for unless we told, nobody wouldn’t never find it.”

I could not help thinking that Tom was right; and now, with my treasure found, and, as it were, banked for my use, I felt lighter of spirit, and we floated easily back in about the quarter of the time occupied in going; when, carefully taking our raft once more partly to pieces, we concealed it behind the rocks, and made the best of our way to the mules.
