The skipper goes in chase of a strange sail.

The violent atmospheric disturbances which accompanied the change of the seasons lasted about a month, after which the weather became tolerably settled once more, though rain now fell, more or less heavily, every day. To work out of doors in the midst of pelting rain was by no means pleasant, although there was no perceptible variation in the usual temperature of the climate. Still there existed in the breasts of all so strong a feeling of insecurity so long as the “fort” remained unbuilt, that they determined rather to suffer the unpleasantness of being daily drenched to the skin than to protract the uneasy feeling of defencelessness which haunted them.

The building, then, was pushed forward with all possible expedition, and, thanks to the indefatigable energy with which they laboured, was so far finished as to be habitable within a couple of months of its commencement, though of course a great deal still remained to be done before it could be regarded as absolutely secure.

The site for this house or fort—for when finished it really was strong enough to merit the latter appellation—was finally fixed so as to include within its limits a spring of pure fresh-water—an adjunct of the utmost importance if it should ever fall to the lot of the occupants to be placed in a state of siege, and it possessed the further advantage of completely commanding both the land and water approaches to the proposed ship-yard. It was built in the form of a hollow square, enclosing a small court-yard (which the ladies determined to convert into a garden at the earliest opportunity) with the spring in its centre. One side of the house was set apart for the purpose of a general living-room; the two contiguous sides were divided unequally—the larger divisions forming respectively the doctor’s and the engineer’s sleeping-rooms, whilst the smaller divisions served as kitchen and larder; and the fourth side afforded ample sleeping accommodation for the remainder of the party, with a store-room in one angle of the building, and the magazine and armoury in the other. The windows all looked outward, but were small, and strongly defended with stout iron bars built into the masonry, and with massive wood shutters inside, loop-holed for rifle firing. The doors giving access to the rooms all opened upon the court-yard, and were as high and wide as they could be made, so as to let in plenty of light and air. For still further security there was no doorway whatever in the exterior face of the building, egress and ingress being possible only by means of a staircase in the court-yard leading up on to the flat roof, and thence down on the outside by means of a light bamboo ladder which could be hauled up on the roof in case of need. The roof, or roofs rather, had only a very gentle slope or fall inward, just sufficient to allow of the rain flowing off, and afforded a fighting platform at a height of about fourteen feet from the ground, the defenders being sheltered by the exterior walls, which were carried up some five feet higher and were also loop-holed. It seemed at first sight a great waste of labour to build so strong a place as this for what they hoped would be a comparatively brief sojourn; but, as Gaunt pointed out to them, there was no knowing precisely how long their stay on the island might be protracted, and if they were going to construct a defence at all, it was as well, whilst they were about it, to construct something which should effectually serve its purpose. And after all, when the work came to be undertaken, it was found that it took but little if any longer time than would have been required to put up a wood house, and to surround it with an effective palisade.

Another month saw the fort so far completed that Gaunt thought he might now safely take in hand the saw-mill upon which he had set his mind; and he and the skipper accordingly devoted themselves henceforward to that undertaking, finishing it within a few days of the date when Henderson reported that all was done at the fort which at that time was deemed necessary. The doctor and his party now took to the woods armed with their axes, and began the important task of selecting and felling the timber for the proposed boat, the design for which Gaunt had been diligently working upon whenever he could find a spare hour or two to devote to the purpose. As ultimately worked out this design was for a cutter, to be of twelve feet beam, forty feet long on the load-water line, and of such a depth as would not only afford comfortable head-room in the cabins, but also give the craft a good hold of the water and make her very weatherly. These dimensions, it was considered, were sufficient for perfect sea-worthiness, whilst the various timbers would be of a scantling light enough to permit of their being handled and placed in position with comparative ease with the limited power at their command. The greatest care was exercised in the selection of the timber, it being necessary to choose not only that which was thoroughly sound, but also such as could without very much labour be conveyed to the saw-mill. This latter necessity, or rather the actual labour of conveying the timber to the mill, caused their progress to be somewhat less rapid than they had anticipated, especially as Nicholls was now busily engaged at the smithy preparing the bolts, fastenings, and other iron work for the little craft; but, notwithstanding all, the work advanced with fairly satisfactory rapidity. It had been decided that the whole of the timber should be cut, sawn, and stacked in the ship-yard before even the keel-blocks were laid down, so that it might become at least partially seasoned before being worked into the hull, and this was accomplished in rather less than a couple of months.

At length the day arrived when, everything being ready, the keel of the vessel was to be laid down—a task which, the keel-piece being cut out of one log, it took the little band an entire day to accomplish satisfactorily. And it was on the evening of this particular day, or rather during the ensuing night, that the little colony sustained a loss which plunged its members into grief so deep that its shadow never entirely left them until long after the termination of their sojourn upon the island.

It happened thus. During the numerous passages of the raft to and fro between the west bay and Fay Island a small reef had been discovered some six miles north of the island, upon which reef, it had been further discovered, a certain fish of peculiarly delicate and agreeable flavour was to be caught between the hours of sunset and sunrise. So very delicious had this particular species of fish been found, that it had become quite a custom for one or more of the men to take the raft after the day’s work was over and go off to the reef for an hour or two’s fishing, thus combining business and pleasure in a most agreeable manner. Captain Blyth especially always partook of the fish with quite exceptional relish; and, it happening at this time that all hands had been too busily occupied for any of them to go out for several days past, the skipper thought he would celebrate so momentous an occasion as the laying of the keel by a few hours’ fishing upon the reef. Accordingly, as the evening meal was approaching completion, he announced his intention, at the same time inquiring if any of the others felt disposed to join him. All, however, confessed themselves to be too tired to find pleasure in anything short of a good night’s rest; and the skipper therefore departed alone, Henderson calling out after him as he went:

“Don’t go to sleep and fall overboard, captain; and keep a sharp eye upon the weather. To my mind the wind seems inclined to drop, and if it does it will probably shift. And I suppose you have noticed that heavy cloud-bank working up there to the westward?”

“Ay, ay, I’ve noticed it,” answered the skipper good-humouredly, but slightly derisive at what he considered the presumption of a landsman in thinking it necessary to caution him about the weather. “Another thunderstorm, I take it—they always work up against the wind; but I shall be back again and safe in my bunk before it breaks. Good-night!”

So saying, Blyth, pipe in mouth, strolled down to the tiny cove in which the punt was moored, cast off the painter, and paddled out to the raft, which rode to a buoy anchored about fifty yards distant from the beach. Arrived alongside the raft he made fast the punt’s painter to the buoy, loosed the raft’s huge triangular sail, mast-headed the yard by means of a small winch which Nicholls had fitted for the purpose, cast off his moorings, and began to work down the stream seaward, the wind being against him. He was not long in reaching the open water, and as he shot out between the two headlands which guarded the mouth of the harbour he noticed with satisfaction that the cloud-bank to which Henderson had warningly directed his attention had already completely risen above the horizon, and was slowly melting away under the moon’s influence. True, the atmosphere was somewhat hazy, and the breeze was less steady than usual; but the general aspect of the sky was promising enough, and if a change of weather was impending it would not, the skipper told himself, occur for several hours yet, or without giving him a sufficient warning to enable him to regain the island in good time.
