We walked along the whole southern shore of the island, and it appeared to us that there were at least three coves to which the Spaniard's description could apply equally well. We found no inhabitants, but there were frequent signs of the Portuguese fishermen who occasionally visit the islet. We saw many foot-prints on the sands, showing that some men had been here very recently. We came across their rough stone huts full of fleas, some of their fishing-tackle, mounds of coarse salt, the ashes of their fires, and in one cavern there were stored the large iron pots in which they cooked their food.
We found no rabbits on the island, and very few birds. The sole creatures on shore were beetles, flies, and fleas. The latter lively insects were a great plague to us at night; it was unwise of us to pitch our camp in the hut of a Portuguese fisherman. On the beach were great numbers of very active little crabs. There was no fresh water on the island.
We ascended the peak, which is named Hart Hill. Its top is formed of rugged masses of coal-black rock, evidently of volcanic formation, and this is studded with large black crystals, like plums in a plum-pudding. These crystals attracted our attention at once. We chipped off some and found them hard and heavy. We began to speculate on the nature of this substance, and, as none of us knew much of mineralogy, we of course at once decided, in our usual sanguine way, that this must be an oxide of antimony, or manganese, or some other valuable product. There were thousands of tons of this stuff on the island, so we clearly saw our way to another vast fortune of a different description to that we were seeking. It was settled that we would obtain a concession from the Portuguese before the value of our find leaked out, then we would sell our rights to an English company or syndicate for an immense sum. We sat there on the top of our crystalline treasure and arranged it all. 'It might be worth while,' suggested one humdrum individual, 'in the first place to send a specimen home to be assayed, so that we may form some approximate idea of the extent of our fortunes; but we must send it to some person whom we can rely upon not to breathe a word of the secret and so stop our chances of making an advantageous bargain with the Portuguese.'
Later on, when we reached Teneriffe, we did send some of the crystals home, and when we arrived at Bahia we were informed by letter of the result of the assay and of the exact market value per ton of the stuff.
But I will not keep any of my friends who may read this book in suspense. They need not apply to me for an early allotment of shares in the great syndicate. We have not made our fortunes just yet. I will anticipate by giving the assayist's report. It ran thus:—'Volcanic hornblende. Commercial value—nil.'
But we did not waste much time in building our castles in the air, and returned to business.
Looking from the summit of our hornblende peak the whole island lay stretched out before us like a map, and we could easily distinguish all the features of the Little Piton, which seemed to be about two miles away. On the Admiralty chart the coast and shoals of the Great Salvage are correctly drawn; but this cannot be said of the plan of the Great Piton: this is utterly unreliable. The survey does not profess to be more than a superficial one, but great changes must have occurred here since it was made. There are not wanting signs that the sea has encroached a great deal on the land, and that it is still doing so. In the first place the island is not three miles long, as shown on the chart; its length cannot exceed one mile and a half. The shores, again, are far more irregular in shape, the outer islands and shoals more numerous, than the chart indicates. Perhaps these last have been cut off the island by the sea since the survey. We perceived that the sea was breaking all round the island on far projecting promontories and shallow reefs; but, strangely enough, where the chart does mark one well-defined continuous reef joining the Great Piton to the Little Piton, there appeared to be a broad open channel of deep water.
We saw one likely-looking bay to the southward of our camp, so, while we were waiting for the yacht, we three of us set to with our shovels, and dug parallel trenches in the sand at right angles to the shore, working upwards from a short distance above high-water mark. We did not dig these trenches to a greater depth than three feet, for we then came to a hard soil which to all appearance had never been disturbed. We found it pretty hard work under that fiery subtropical sun, unaccustomed as we were to the use of pick and shovel.
In the afternoon the yacht appeared off the island; so we signalled to her with the flag in the preconcerted manner: 'Come to an anchor.' 'We will pass the night on shore.' And, whereas eight or more waves of the flag were to signify that we had found a likely place for the hidden treasure, we waved most energetically for quite two minutes—a sanguine signal that must have led my companions on board to conclude that we had at least discovered the first of the chests of dollars.
The yacht came to an anchor off the bay at which we had first landed. The mate came off to us in the dinghy, and I told him our plans and instructed him to send other hands off to us in the morning, together with all necessary stores. He then returned to the yacht, while we passed the night in our hut in the company of the innumerable sleepless fleas.
