“Well, Dick, where is the treasure?” she banteringly demanded. “Surely it is not so very difficult to find, now that you have been told of its existence?”

“Oh, I’ll find it, never fear, young woman!” I answered; “but I confess that it is so ingeniously concealed that I doubt whether anyone ignorant of its existence would find it, except by the most extraordinary accident.” And therewith I proceeded to grope and feel about in the various fissures and cavities with which the rocky walls of the small cavern were honeycombed, but without success. At length, to my great chagrin, I was obliged to abandon the search and confess myself beaten.

“Yet it is very simple—when you know!” remarked Lotta, in high glee at my discomfiture. “Follow me!” And, dropping upon her hands and knees, she proceeded to crawl into one of the cavities that I had been searching, and which I should have declared was not nearly capacious enough to receive a full-grown man. Nevertheless Lotta completely disappeared within it, and I after her. When I had fairly entered the cavity I found that what had appeared to be its back wall, and which gave it the appearance of being only about two feet in depth, was really one of two side walls, a narrow passage turning sharp off to the right, just wide enough and high enough to travel through comfortably on one’s hands and knees. It wound round in what seemed to me to be about a half-circle of about fifty yards in diameter, and its inner end gave access to an enormous cavern, very roughly circular in shape, and about four hundred feet across in either direction.

It was a most extraordinary place. One of the peculiarities was that, instead of being pitchy dark, as one would naturally expect it to be in such a place, the whole interior was suffused with a very soft greenish twilight, quite strong enough, when one’s eyes became accustomed to it, to permit one to see from one end of the cavern to the other with quite tolerable distinctness. Where the light came from it was impossible to say, for the roof of the cavern appeared to be formed, like the walls, of solid rock; but from the fact that shafts of light were plainly visible overhead, issuing from the walls and roof, I conjectured that the light entered the cavern through rifts in the rock, and that its greenish tinge was imparted to it by the foliage through which it filtered prior to its passage through the rifts. Greater surprise was in store, for presently I discovered that the walls were literally covered with sculptured figures of men and animals, done in high relief, and about life-size. The sculptures appeared to be records of hunting and fighting episodes, and were executed with great vigour and skill. In reply to my astonished enquiries, Lotta informed me that Ricardo attributed this work to the original Caribs, and very probably he was right.

The treasure was all neatly arranged in a recess near the narrow passage by which we had entered the cavern, and a pretty careful inspection of it soon convinced me that Ricardo had been only speaking the truth when he assured me that, although it was probably the booty of some dead-and-gone gang of pirates, he had certainly had no hand in its accumulation. For everything bore unmistakable evidence of having lain where it was for a great many years—probably at least a hundred, if one might judge by the dates on a few of the coins which I examined, and which formed part of the treasure. The man who accumulated the store must have been an individual of a very enterprising nature, for there were great piles of strong, solid wooden cases packed to the brim with doubloons and pieces-of-eight; two hundred and eighty-five gold bricks, weighing about forty pounds each, every brick encased in the original raw-hide wrapper in which it was brought down from the mines, now hard and dry and shrivelled; quite a large pile of rough, shapeless ingots of gold and silver, conveying the suggestion that at various times large quantities of gold and silver plate and jewellery had been run through the melting pot; and, finally, a leather bag containing not far short of a peck measure of gems of every conceivable description, all of the stones being cut, and evidently taken from pieces of jewellery of various kinds that had probably been broken up and melted. I had not the most remote idea of the value of the whole, but I was convinced that it must be something fabulous, and I afterwards learned that I was right.

We spent nearly two hours in the cave, partly because there was so much of interest there to engage our attention, and partly because of its delightfully cool temperature, which was a positive luxury after the extreme heat of the house, both by day and by night. Before we left the cave to return to the house, Lotta half-jestingly proposed that we should stock the place with provisions, and use it as a place of abode whenever the heat became unduly oppressive. Although the suggestion was made more in jest than in earnest, the idea became so attractive, when we proceeded to discuss it further, that on the following day we actually took steps to carry out the proposal. We spent the best part of the day in stocking the cavern with provisions, rugs, and so on, to such an extent that we could easily have endured a week’s siege there, had it been necessary, for a good supply of excellent water had been found percolating through the rock in a small side passage off the main cavern. And thereafter we regularly spent a great part of each day in the cavern, always making it a rule to take with us a little more of everything than we really needed.

At length, when a period of two full months had elapsed since the sailing of the Barracouta, with no sign of her return, I began to feel somewhat anxious. I was now practically as well in health as I had ever been in my life, and I began to pine for a return to active service. I was also desirous of seeing Lotta safely removed from her present dubious and somewhat dangerous surroundings into that position which was hers by right. To achieve these two results it was necessary that I should get away from where I was, either by the fulfilment of Ricardo’s promise to me, or by some other means. To get away from where I was! As that expression occurred to me I suddenly remembered that I had not the faintest idea where I was; and, since Lotta was as ignorant as I was on the subject, I determined to ascertain by some means exactly where this little paradise of a spot was situated. And, as a first step toward this, I ascertained roughly the latitude of the spot, by means of a quadrant that I found in Ricardo’s room, as a result of which I discovered that I was undoubtedly somewhere on the island of Cuba. Since there were only two spots on the coast line of the island that could possibly have this precise latitude, I very soon managed, by reference to one of Ricardo’s charts, to determine that the rendezvous was on the north side of the island; nay, I was able without difficulty to identify the precise spot on the chart.

Another week passed, still with no sign of the return of the Barracouta, and my impatience to get back to civilisation and friends grew so acute that I was seriously entertaining the idea of stealing a boat from the dockyard and making my escape in her. The only consideration which caused me to hesitate was, that as I fully intended to take Lotta and Mammy with me, I did not care to expose them to the perils and discomforts of a boat voyage until every other resource had failed.

A few more days had passed, when, about two o’clock one morning, I was rudely awakened by some individual who had entered my room and was roughly shaking me by the shoulder. I started up in bed and, quickly gathering my confused wits together, recognised the voice that was addressing me as that of Fonseca, the surgeon of the Barracouta!

“Hullo, Fonseca,” I exclaimed, “where in the name of fortune have you sprung from? Is the Barracouta in?”
