“Humph!” ejaculated Tom, who did not look at all pleased; “it’s very big, and large, and cool. But say, Mas’r Harry,” he exclaimed, brightening up, “it wouldn’t make half a bad place for keeping tallers! Yah! what’s that?”

“Only a bird,” I said, as with a rush a couple of large birds had flown close by us, evidently alarmed at our visit to their home. “That’s a good sign, Tom, and shows that you need not fancy there’s an enemy behind every block of stone. If anyone was within those birds would not be there.”

Tom grunted, and then, as if to show his unbelief, cocked both barrels of his gun, as, with eyes each moment growing more familiar with the gloom, we walked slowly forward into the darkness ahead—slowly, for the floor was rugged in places with fragments from the roof, and stalagmite. The roof was about fifty feet above our heads, and the span of the low corrugated arch, I should say, a hundred more than that. The stream was rippling noisily along, threading its way amongst the massive blocks of stone, murmuring musically over pebbles and sand. Now our way was wet and slimy, and then again rugged and dry, till, having penetrated some little distance with every precaution, we turned round to look back at the entrance, to see as pretty a picture as ever I gazed upon in my life. We could now see plainly the nature of the roof, hung with beautiful stalactites of many graceful forms, giving to the great arch the appearance of some grand specimen of Gothic tracery, through which we looked upon the ravine lit up by the outer sunshine, with its green, and gold, and blushing floral hues. It was a scene to be remembered for ever; but the gold in my thoughts seemed more glorious, and I turned from it without a sigh.

Another dozen yards and a curve in the cave hid the entrance from sight; we were in gloomy shades, where a light was necessary; and before going farther I paused to think.

If the treasure had been hidden there, where would it be?

Reason said directly, in the most distant and inaccessible recesses of the vast cavern.

And where was that? How far from the light of day?

That was the problem I had set myself to solve, and, in spite of a feeling of awe with which the place inspired me, I prepared for the solution. It was no light task, and I have no shame in owning that I felt a strange reluctance to proceed along a rugged path wherein might at any time be yawning some fearful bottomless chasm, ready to swallow up the adventurer; but I would not show my dread, and if Tom felt any he was too obstinate to show his.

By means of string we tied each a candle to our pistol barrels, and then set forward, walking slowly, now with the floor of the cavern ascending, now with it sloping
