This channel was even more promising than the one which we had just emerged from, being almost double the width; but we were puzzled for the moment as to which direction to take, whether to head to the northward or the southward. The northerly-trending channel might lead anywhere; the southerly portion, on the other hand, looked as though it might possibly take us back to the ship, the spars of which were visible some nine miles away. We decided to try the latter, as the day was by this time well advanced, and, should we ultimately find ourselves obliged to retrace our steps, it would make us very late in getting back to the ship. Fortunately, however, we were not driven to this latter alternative, for after following the winding course of the southerly channel for a distance of some twelve miles we arrived at the north-eastern extremity of the basin in which the Mercury lay at anchor, and safely arrived alongside half an hour later, having spent the day in circumnavigating a portion of the reef which we thus discovered to be entirely surrounded by channels of a width and depth of water sufficient to allow of the passage of the ship. This discovery, however, was of no practical service to us; for it still left us in our original state of uncertainty regarding the existence of a channel through which the ship might be taken into open water.
The narrative of our efforts to find such a channel has been given thus far with considerable detail, in order to bring home to the reader some idea of the extreme awkwardness of our situation, and the difficulties and perplexities with which we found ourselves confronted; but there is no need to continue the story further in quite so detailed a form, since the progress of our researches was unaccompanied by anything in the nature of adventure. Let it suffice, therefore, to say that we traversed the multitudinous canal-like channels of that labyrinthine reef continuously for ten days longer before we found a passage of sufficient width, and with a sufficient depth of water in it everywhere, to enable the Mercury to go through it to the open sea. This passage, when found, proved to be a continuation of the channel originating in the north-eastern angle of what we had now come to speak of as the Mercury Basin, from the fact that the ship lay anchored in it. Although it was an undoubted fact that we had actually found a channel leading from this basin to open water, the difficulties in the way of successfully carrying the ship through it were so great that we had very grave doubts of our ability to accomplish it. In the first place, the course of the channel was of so winding a character that, according to a very careful estimate, the ship would have to traverse no less than a hundred and ten miles of waterway before clearing the reef; consequently it would be impossible to accomplish the whole distance during the hours of daylight of a single day; while to attempt the navigation of any portion of it during the hours of darkness was altogether too hazardous an undertaking to be calmly thought of. But, as though this difficulty were not in itself sufficient, there was a stretch of twelve miles of channel running in a north-easterly direction which the ship could not possibly negotiate under sail unless a change of wind should occur—of which there seemed to be absolutely no prospect. The only alternative, therefore, would be to kedge those twelve miles; truly a most formidable undertaking for four persons—one of them being a girl—to attempt. Fortunately, however, for us all, the problem of how to overcome these tremendous difficulties was solved for us by accident, and quite unexpectedly. For, upon going over this long and intricate channel again, in order thoroughly to familiarise ourselves with it, and to become better acquainted with its many danger-points, it happened that on the return journey—which was being made by moonlight—we missed our way, continuing along what appeared to be the main channel, instead of diverging into a branch trending to the eastward; and by the time that we discovered our mistake we were so favourably impressed with the appearance of this new, strange channel—which seemed to be running almost straight toward Mercury Basin—that we determined to follow it up and see whither it led.
Not to dilate unnecessarily upon this portion of our adventures, we discovered, to our infinite satisfaction and delight, that it did indeed ultimately conduct us back to the ship; and that, too, by a route which reduced the distance to be travelled to about forty-five miles, or very considerably less than half that of the other channel. Moreover, while the original channel first ran north, then north-east, for the twelve miles that were only to be covered by kedging—before it ultimately changed its course to south—in which direction the point of ultimate egress lay, the new channel left Mercury Basin at its western, or leeward, extremity, running first west, then south-west, and ultimately south, straight out to sea. Thus the whole distance could be traversed under sail and with a free wind. The three following days and nights were devoted to a most careful re-examination of this new channel, with the result that we thoroughly satisfied ourselves as to its absolute practicability.
With our minds thus relieved of a tremendous load of anxiety, we felt ourselves once more able to turn our thoughts in the direction of our pearl harvest. A full fortnight had been devoted to the exploration of the reef since our last visit to the oyster-bed, and we were of opinion that it ought by this time to be in such a condition as to afford us a very handsome return for our labours.
Accordingly, after allowing ourselves a day’s rest to enable us to recover from the fatigues of our recent arduous boat duty, we once more repaired to the oyster-bed—Grace Hartley preferring on this occasion to remain “at home”, as she put it, rather than again face the disgusting sights and odours that had met her on the occasion of her visit. But upon our arrival at the scene of operations we soon found that a fortnight had made a vast amount of difference in the condition of the oysters. For whereas when we had last visited the oyster-bed the process of putrefaction had only just begun, it had now advanced so far that the fish were not only completely decayed but had also in many cases so completely dried up under the influence of the sun’s rays as to have, to a very great extent, lost their odour. Furthermore, the birds had been so busy that more than half the shells had been completely emptied; our task, therefore, although still excessively disagreeable, promised to be far less revoltingly offensive and disgusting than it had been before. Even such offensiveness as still remained we contrived to mitigate to a very considerable extent, by adopting the simple plan of starting work on the windward edge of the bed, whereby the accumulated odours were blown away from us, instead of directly in our faces, as on the previous occasion.
Now we went to work systematically, roughly dividing the bed into three nearly equal portions, one of which was to be gone over very carefully by each of us. Also we each had a bucket, into which to drop our spoils, so that there might be no time lost and no unnecessary fatigue incurred in passing to and fro. Our system of working was simplicity itself, and merely consisted in starting operations on the extreme weather side of the bed, examining the fish just as they came to hand, extracting such pearls as they contained, dropping the gems into the bucket of water with which each of us was provided, and then throwing the shells out on the reef apart from those still untouched. We toiled on thus all day, with a pause of half an hour about midday, when we retired to the boat, cleaned ourselves as well as we could, and snatched a hasty meal, concluding our labours about half an hour before sunset. When, during the run back to the ship at the end of the day, we proceeded to compare notes and take stock of the results of our labour, we came to the conclusion that either the bed was an enormously rich one, or that we had had an exceedingly lucky day, for our combined booty consisted of over fourteen hundred pearls—sixty-three of which were of quite exceptional value from their size or colour—and a full quart measure of seed pearl. I was of opinion, at the time—and am so still—that we might have obtained considerably more than we did of the last, but for the eagerness with which we prosecuted our search for the larger gems, which caused our search for the smaller seed pearls to degenerate into a very perfunctory operation.
The story of one day’s work at the oyster-bed is the story of all; it is therefore unnecessary to say more upon the subject than that we spent a full fortnight upon the task of gathering pearls, by the end of which time we had acquired so much dexterity at the work that we did more in one day than we did in two at the beginning of our labours. Then, although at the expiration of the fortnight we seemed to have made scarcely any perceptible inroad upon that enormous deposit, we grew tired of our self-imposed task and mutually agreed that we had accumulated as much wealth as we required. Moreover, as we watched the increase of that wealth day by day, our anxiety grew lest perchance anything should happen to prevent our escape from the reef and our return to that civilisation, where alone our wealth could be of any real value to us. The reader may reasonably ask what grounds of justification we had for the fear that anything could possibly happen to prevent our escape, seeing that we had been fortunate enough to discover a channel through which the ship might be easily taken out to sea; but I think we all still carried a vivid recollection of the terrific natural convulsion that had placed us in the extraordinary situation which we then occupied; and I believe the others shared with me the feeling that, such a thing having once happened, it might possibly happen again. The reef that had held us prisoners for so long might sink again to the ocean depths, perchance carrying the ship with it in the terrific turmoil that must ensue; or it might be hove up still higher, leaving the ship stranded and immovable; and then what would be our plight? Therefore, when on the evening of a certain day Gurney ventured to voice the suggestion that it would now be well to think seriously of making good our escape, while yet the opportunity to do so remained to us, neither of the others raised so much as a single word of protest, but on the contrary agreed to the proposal with an eagerness which clearly showed how welcome it was to us all.
“As for me,” said Gurney, when walking the poop with me that night and discussing the matter, “my way is now clear; Gracie and I will get married as soon as we arrive in Sydney; and then I think I may venture to return home and once more hope to find a welcome beneath the roof-tree which shelters those to whom I have given so much sorrow.”
“Indeed,” remarked I, scarcely knowing what to say, for my companion had spoken those last words in a tone of such intense feeling that I felt convinced a story must lie behind them.
“Yes,” he said, and was silent for a minute or two, apparently plunged in deep and painful thought. Then, suddenly throwing up his head, he continued: “I belong to the genus Prodigal Son. Would you care to hear my story? I think I should rather like to tell it you; for you are a good lad, high-spirited, full of generous impulses, eager to excel, and full of pluck. You are bound to make a success of your life if you will only steadfastly follow the path that your feet are now treading. But—forgive me for saying so—the qualities that you possess, excellent as they are, are precisely those that, unless you are very careful, are likely to betray you.
