It soon became apparent that the cavern was spacious enough to accommodate a very much larger party than ours. It was so extensive, indeed, that we were obliged to defer its complete exploration for lack of a sufficient number of torches; but we saw enough of it to determine us to enter upon its occupation forthwith. Accordingly I made my way to the beach where we had left the boat, and proceeded to transfer our few belongings from her to the cavern. Those belongings were not very many, consisting, in fact, merely of the empty water breaker, the arms and ammunition, the carpenter’s chest, and the few planks that I had found afloat in the lagoon after the sinking of the wreck; and I succeeded in effecting the transfer of the whole before sunset.

Thus far I had been much too busy to attempt anything in the nature of an exploration of the entire island; but now that a safe shelter had been found for the party—and one capable of being very effectively defended, too, if the necessity should arise—I felt it was high time to make myself fully acquainted with our new home and its capabilities as at least a temporary abode. I was especially anxious to ascertain beyond all question whether it harboured any other inhabitants than ourselves; therefore, on the morning after we had installed ourselves in the cavern, I took a rifle, filled my pockets with cartridges, and set out with the intention of making the complete circuit of the island. I left Julius in charge, and warned my companions not to be anxious on my account, should I not return by nightfall, as I meant to take my time and explore the island thoroughly before returning.

Starting from the cavern immediately after breakfast, I proceeded southward, and, descending to the beach, indulged in a swim as a preliminary. Then, returning to the top of the cliff, I continued my way southward until I reached a point overlooking the harbour entrance, from which I struck inland toward one of the two inferior elevations previously mentioned.

The base of this mound was completely surrounded by trees, intermingled with an undergrowth so dense that it was only with difficulty I was enabled to force a way through it. I wished to reach the top of the mound, if possible, because it appeared to be a very suitable spot upon which to build a big flare for the purpose of attracting the attention of ships, should any such chance to heave in sight; I therefore persevered, and eventually came out at the base of the elevation, which was clear of trees. Then I started to climb, and after an hour’s arduous toil reached its summit, the sides being exceedingly steep and consisting for the most part of fine ashes, from which I suspected that I was climbing the cone of an extinct volcano. This suspicion was fully verified when I arrived at the top; for I found myself upon a narrow platform, roughly elliptical in shape and some half a dozen yards wide, from which I gazed down into the interior of a crater some two hundred feet deep, the sides of which were nearly vertical, while the bottom was apparently a shallow pool of stagnant water.

The rim would serve admirably as a site upon which to build a bonfire; but the sides were so steep and the soil so loose that I foresaw it would be difficult, almost to the point of impossibility, to climb them with a load. I therefore decided to see whether the peak near the centre of the island offered better facilities. But before descending I took a good long look round the horizon, and was not very greatly surprised to discover that there were no less than seven separate and distinct indications of land to the northward, the nearest of which I judged could not be very far away.

I walked round the rim of the crater to its northern side and made my descent there, en route for the peak near the centre of the island, having first fully satisfied myself that the sea all round was entirely bare of craft of any description. My way now lay again through timber and more or less dense scrub, beyond which I found a small patch of open grass land, and then more timber. But now, for some inscrutable reason, there was little or no scrub. The trees were more lofty and wider apart, and intermingled with what I may term the timber trees were a fair number bearing fruit, among which I found several specimens of the breadfruit, and an abundance of mangoes, guavas, custard and star apples, plantains, bananas, and a few other varieties; thus there was the assurance of an ample supply of food so long as we might be compelled to remain upon the island.

It was past noon when I reached the base of the peak; and I had no sooner come to it than I perceived, from the ashes and scoriae that thickly strewed its sides, that it also was a volcano. Yet I was determined to climb to its summit, if possible, if only for the perfect panorama of the entire island that I knew I should obtain from there; so I rested for a little while, utilising the time by making a good meal of fruit, and then addressed myself to my task.

The sides of this volcano were not nearly so steep as those of the other; the dust and ashes, however, were just as fine, rendering the task of climbing the slope extremely difficult. But I had learned wisdom by this time, and instead of attempting the ascent in a straight line from base to summit, I described a spiral round the peak, and in this way accomplished the ascent in almost as short a time as, and with far less fatigue than, if I had attempted to go up by the shortest way.

My conviction that this peak also was the vent of a volcano was verified the moment that I reached the summit, the general aspect and character of this and the other being almost identical. The rim on which I now stood was, however, quite three hundred feet higher than the first; the view from it was consequently much more extensive, and in addition to the seven indications of land seen from the top of the mound, I was now able to trace three more quite distinctly, while in the farthest distance I thought I could descry the faint loom of still more land. This, however, was not all, for far away to the northward—so far as to be no more than just visible—I caught a hint of a faint, pearly gleam on the horizon, which I felt certain could only be that of the sun on a ship’s white sails; and my heart swelled with thankfulness, for here was an unmistakable assurance that craft of some sort occasionally visited these waters.

Having at length thoroughly searched the entire circle of the horizon, I turned my gaze nearer home and proceeded to view the island, the whole of which lay spread out beneath me like a large-scale relief map.
