CHAPTER THE FIFTEENTH
OF THE SEVERAL SURPRISES THAT AWAITED BILLY AND THE NARRATOR AND THE CREW OF THE LOVEY SUSAN; AND OF OUR ADVENTURES IN THE CAVE
"I say, master," said Billy, as we toiled up towards our house, "you and me'll think twice afore we go a-cruising again. I ain't never been so tired in my life, and I shan't be awake to eat no supper."
"Very well," said I, "we won't trouble to make up our fire, but——"
Unexpected Visitors
The words died on my lips, and we both stood stock still at the same moment, for there had come to our ears on a sudden, from the direction of the house, the sound of loud and boisterous laughter. Little John yelped, Billy clutched my hand, and you will scarce believe it, but we were both trembling like leaves in the wind; for imagine if you can what a shock it was to us, after our loneliness on the island, to hear the laughter of men.
"They've got here first," says Billy in a whisper presently.
"Who?" said I.
"Why, the savages," he said. "They've spied on us. We'd better go back for our spears and things."
I agreed that this was a prudential measure, and we trudged hastily down again to the canoe, and took our spears and bows and arrows, and then retraced our steps, the dog accompanying us. We crept up with exceeding caution until we reached a spot whence we could overlook the hollow in which our house was situated; but or ever we got there we were aware of a red glow, as from a huge fire, and when we came to the summit of the crest and looked down the long slope towards the hut, near half-a-mile away, we saw that in front of it a very large fire was kindled, which lit up all the country around, and on the fringe, so to speak, of the illuminated space certain dark figures moved.
"They've made the fire ready to cook us," says Billy, his voice trembling very much.
"Nay, they're cooking already," I said, and showed him that they had set our great tripod over the fire, and something dangled from it roasting.
"They've stole one of our pigs," said Billy in great anger; indeed, his first fear was now swallowed up in this new emotion. He spoke pretty loud, and the dog, knowing from his manner that something was amiss, began to yelp. I bade Billy hold his peace, for we must creep silently towards the house and discover who these visitors were: and since the dog might betray us if he yelped as we approached, we thought it best to tie him to a tree; he would doubtless yelp there, but the visitors would suppose he was a wild dog. We had just left him tied up when I remembered that if his yelping brought the wild dogs about him he would very soon be torn in pieces, so we had to go back and loose him, and then Billy took him in his arms and said he would keep him quiet, which he did.
We crept along, being careful to take cover from the trees and shrubs, and so not following a straight path, but working round somewhat until we came to the back of our fowl-house, whence we could see and overhear what was going on. But before we got there we had another amazing shock, and a very disconcerting one too, for as we were walking Billy all of a sudden clutched me by the arm and whispered, "That's Hoggett," and then he uttered that profane word which I had never heard upon his lips since the first day we came to the island. And sure enough, when we came to the fowl-house, and could both hear and see them, grouped about the fire beyond it sat or lay or stood a dozen of Billy's once shipmates on the Lovey Susan, the mutinous crew of my uncle's ill-fated vessel. Some of them, being on the farther side of the fire, we could not see clearly: but on this side there was Hoggett, Billy's especial enemy, and Wabberley; and Clums the cook, attending to the fine pig, one of our best, that was roasting; and Chick, and Pumfrey the ship's carpenter, and others whose names I need not write. Billy was for fitting an arrow to his bow and shooting Hoggett that instant, but I forbade him, in a whisper but peremptorily, for the two of us could not hope to get the better of a dozen, when they had firearms too, for I had spied a musket standing against the wall of the hut, near to where Hoggett was lying. Besides, I own I felt a certain tenderness towards these men, rough and brutal, aye, and treacherous, as they were; for they were men of our race and speech, and to hear my own language from the lips of Wabberley brought back to me those evenings when he feasted my uncle with his stories, so that he gave me thoughts of home. However, I felt a natural indignation at seeing these uninvited guests making free with our property, and after hearing somewhat of their talk I ceased to feel any kindness towards them.
They were talking, I soon discovered, about the house and its owners, and Hoggett declared that he was certain sure it belonged to savages, an opinion which Wabberley instantly controverted.
"Have I, or have I not, been in these here South Seas afore, Tom Hoggett?" I heard him say, and Hoggett growled that he said he had; whereupon Wabberley continued, "Well then, I ask you again, didn't we leave they two striplings on this very island?"
"You're right, there," says Hoggett, "and one of 'em the sauciest, snarliest son of a" (here a dreadful word) "that ever escaped his proper lickings."
("That's me," whispered Billy, in a great rage.)
"True, but handy all the same," said Clums. "He could do a thing or two with his tools, and I warrant you he made this;" and so saying, he took up Billy's toasting-fork, and held a yam to the blaze.
"'Twas Billy made it, sure enough," said Pumfrey, "for the other chap couldn't ha' done it."
"No, not him," said Wabberley. "He was a overgrown weed, he was, all stalk and no head to it, and I reckon if the truth was known he made this; any fool could do it," and he took up, as it chanced, one of the two-pronged forks that I had made, and of which I was a little proud at the time.
"That's true, Nick," says Joshua Chick, "and what's more, shipmates, no savage ever made a fork in his life, and lor' bless you, didn't we find a hairbrush and a comb, and what savage ever wanted such, d'ye think? And that there pig-sty, now, ain't that like the one where you was brought up, Pumfrey, only a bit rougher, maybe?"
This question was very much resented by Pumfrey the carpenter, who declared hotly that he had built pig-sties, not lived in 'em, and whoever made this pig-sty was a very poor hand at it. To this Wabberley assented, and went on to say that the dirtiest savage as ever breathed would have been ashamed of the miserable things we had made in the way of pots and baskets and other things. It was plain that they had pretty thoroughly ransacked our hut, and I was on thorns lest they should have discovered our secret store-house below, which it appeared, from what followed, that they had not done, and thankful I was. One of the men asked what we lived on, for we couldn't eat, he supposed, nothing but pork and chickens, and they had found nothing else, except the yams in the pig's trough, we having put all the rest of our fruits and vegetables in the store-house.
"Ain't there plenty of trees on the island, donkey?" said Clums. "You may take your davy there's bread-fruit and bananas and cocoa-nuts and such like, and they pick 'em when they want 'em."
"But where are the young devils?" said Hoggett. "Ain't that there pig done yet, Clums? The smell makes me want to get my teeth into him."
"One more turn," says Clums, "and then we'll have a better supper than we've had many a day."
"I say, where are the young devils?" says Hoggett again. "D'ye think they see us a-coming and sheered off?"
"Like as not," said Wabberley, "but we'll find 'em to-morrow, and they shall get our dinner for us, d'ye see. I believe in taking it easy and letting the youngsters do the work, I do. Did you get all the yams out of that pig's trough, Clums?"
"I did," says he, "and there must be some more growing somewhere, and 'tis to be hoped things ain't so short as they are in our island, mates. Did you ever know food go so fast? There seemed enough for thousands when we landed there, and you wouldn't ha' thought a score of men would ha' made such a hole in it."
And then they fell a-talking of the eight or nine men they had left on what they called their island, and I judged from their discourse that provisions being short with them, these twelve had come away to discover a more plentiful land, having promised, if they found one, to return and fetch their shipmates. Pumfrey reminded them of their promise, adding that the men would certainly starve if they were not brought off, whereupon Hoggett declared with an oath that he for one was not going to tug an oar for twenty miles in a leaky boat, to bring off a lot of useless blockheads who would soon eat them out of house and home. We pricked up our ears at this, Billy and me, hearing for the first time that our visitors had made up their minds to abide with us, and Billy ground his teeth, and whispered that we should have to fight 'em. One of the men—I think it was Wabberley—asked what about the mountain? and said he didn't like the notion of living where he might be boiled or roasted any day. At this Hoggett made a mock of him. "Ain't it years since we left they boys here?" he said. "Does it look like boiling or roasting, 'cept for pigs? These here burning mountains ain't always a-working, that's plain, and this one here may be asleep for fifty years to come."
And then they ended their discourse for a time, devoting themselves to the roast pork and the yams of which they had deprived our pigs, sighing also very heavily for beer; and finding no cocoa-nuts handy for quenching their thirst, and being too lazy to fetch any (besides, it was dark), two of them went with pots in their hands to the lake, on which there was a very pretty reflection of their fire, and brought them back full of water. Billy chuckled so much at this that I was afraid he would be heard; but I was amused too, for there having been no rains lately, we knew what the effect of drinking the water would be; and, indeed, the next night we heard the men condoling with one another, and it was plain that when they were seized in the middle of the night with griping pains, they believed one and all that they were poisoned.
They had eat such a monstrous supper that they were fit afterward for nought but swinish slumber, and the most of them lay where they were, never intending to stir until the morning. Two or three, however, took up their quarters in the hut. We did not observe that they set any kind of watch, which was certainly a point of carelessness, and Billy said it would be easy enough to steal upon them in the night and kill them all, but this of course was not to be thought of. When we saw that all was quiet we stole away back to the canoe, both to get our own supper from the surplus of our provisions, and also to have a sleeping-place. Since we did not know how long this rascally crew would remain on the island, we thought we ought to convey what smoked fish and salted pork we had in the canoe to the thicket on the side of the mountain; as for the bread-fruit and cocoa-nuts, there was no need for us to trouble about these, the trees being exceeding well laden with them. And considering that it would be foolish to let the men see our canoe, when we had taken the food up the mountain, very toilsomely, we being so tired, we worked the canoe round the island with extreme care, until we came to the little cove in the cliff which we had seen near the archway in our voyage of circumnavigation. There we slept by turns till break of day, finding it a matter of the greatest difficulty to keep awake when our turns came for watching; and when it began to be light we unshipped the mast, and clambering along the base of the cliffs we made our way gradually upward until we reached the thicket, where we deemed it best to remain in hiding. We heard nothing of the men all the morning, and guessed that they were not in very active trim after their medicinal draught of the night before; but in the afternoon we heard them talking to one another from various parts of the island, from which it was plain that they were searching for us. Once, indeed, they came so near us that we were fearful of being discovered, and kept very close in the depth of the thicket; but they passed us by, and I wondered that they had been brave enough to come so far up the mountain, remembering their panic on the day they landed.
Dispossessed
Making our meals chiefly of salt fish, we grew very thirsty, and did not dare venture down to the woods where the cocoa-nuts grew, lest we should be seen. But we thought we might creep round the mountain, until we came to the place where the hot spring fell towards the Red Rock, and there we filled some large leaves with the water, and let it stand until it cooled, and then drank it, without any harm. And as we returned to our hiding-place I chanced to see some pieces of that rock I have before mentioned, what Billy called the fizzy rock, that which belched forth great clouds of poisonous fume when it was touched with water. The sight of this set an idea jogging in my head, which I did not tell at that moment to Billy because of his natural impatience; but when it was dark, and we had got down safely to the place of the former night's watching, and assured ourselves from the men's talk that they had no present notion of leaving the island—at this time of night, I say, I communicated my notion to Billy, and he applauded it with great enthusiasm. As soon as ever the first glimmer of light came, therefore, we might have been seen very busy gathering lumps of this rock, which we piled in two heaps, one about the spring near the top of the mountain, the other about the spring that flowed down the lava bed. We worked very hard at this, and I observed with great satisfaction that the cloud of steam above the mountain was a trifle thicker this day than it had been for some time past. Then we waited until the men were at their breakfast (we could see them easily from the edge of the thicket, which commanded a view of the house and its surroundings), and when they were in the midst of it, we hasted to these springs, Billy to one and I to the other, and began to topple into them the fragments of rock which we had gathered, being exceeding careful to keep to the windward side. The wind was blowing, as it did nearly always, in the direction of the house, so that when the dense and filthy smoke rose from the rock we had cast into the water, it was carried away into the interior of the island.
A Stratagem
Having set this storm a-brewing, as you may say, we made haste to regain our place in the thicket, whence we could see what went on below. We were delighted beyond measure, and Billy began to caper, as he always did when pleased, when we saw the men spring to their feet and, leaving their breakfast, set off in a mighty hurry toward the beach. We had not seen the place where they had left their boat, but guessed from the direction of their flight that they had drawn it up at the east end of the sandy beach, near the lava tract, indeed, at pretty nearly the same point as they had landed at three years before. We perceived that one or two of the men halted as they ran, and turning about, looked up at the mountain and then called to their fellows. Though we could not hear their words, the distance being too great, we guessed that they were shouting to their comrades to wait a little, in case the apparent explosion turned out to be of no account after all. But the other men did not halt, nor even slacken their pace, and Billy and I laughed a good deal to see Wabberley, who was much the fattest of them, yet easily outstrip the rest, so much did panic lend lightness to his heels. Their manifest terror appeared to shake the resolution of the few hardier spirits who were inclined to pause. Without any further delay they sped on after the others, and when they had disappeared for a little from our view behind the rocks, we saw a boat put off very soon after, going towards the south, whence we presumed it had come. But it had not gone far when it stopped, and we saw at the same moment that the fumes were being dissipated in the air, which perhaps made the men think that the danger was over. We could not venture to go again to the spring above the lava tract, which was plainly to be seen from the sea, but we went back to the other spring, where we were perfectly screened, and hurled great quantities of the rock into the water, so that we were nearly overcome by the acrid fumes. But we persevered until we had raised an immense cloud of smoke, much denser than before; and running to the thicket to see the effect of our handiwork, we were almost beside ourselves with joy when we saw the boat proceeding at a good pace towards the south-east. We watched it until it had finally disappeared, and then we hastened down to our hut, wondering whether it had suffered any damage at the hands of our visitors, and also whether they had left any of their own belongings which would be useful to us, being exceeding jubilant also at the wonderful success of the trick we had played on them.
We Regain our Own
When we came to examine our little demesne, we were in a great rage, for the men had not only killed our finest pig and two or three of our chickens, but had also turned the hut upside down, as people say, and ransacked everything. Of course they got little for their pains except the food, and they had not discovered our cellar, nor even the pit outside the hut where our bread-fruit pulp was stored, what there was left of it, for since we had used the cavern for a store-house we had been under no necessity to keep the pit replenished. They had left behind them nothing but one musket, which had no doubt been overlooked in their haste, and a cap which Billy declared was Hoggett's, though I myself thought it was Wabberley's. The musket was useless to us, having no powder or shot, though it would make a capital club; and as for the cap, whether Wabberley's or Hoggett's, neither Billy nor I was in the least inclined to wear it, being very much worn, and filthy to boot, not fit to be compared to our own light and cleanly bonnets, which we wore pretty constantly now, to preserve us from sun-stroke.
Though we had not suffered any great damage, I was very much disturbed by this sudden visit of the seamen. We had heard enough of their talk to guess that they had been driven to make their expedition by scarcity of provisions, for had they been living in ease and plenty they would hardly have risked so long a voyage in a leaky boat. Whether they had visited other islands first we could not tell; but I could not help fearing that if it was dearth that had impelled them, they would come again, braving the dangers of the volcano. Cowards though they were, they would certainly come to their senses before long, and when they considered that we had a fair-built hut, and a plantation, and a piggery and fowl-house, which had plainly received no hurt from the mountain, they would be pretty sure to come back if they found no means elsewhere of stocking their larder.
"Perhaps they think we have gone away from the island," said Billy, when I talked over the matter with him. "They will think Old Smoker frighted us too."
I saw there might be some truth in this, but I said that if it were so, they would probably keep a careful watch on the mountain for the future, and if they saw no signs of its breaking forth they would return, confident of enjoying the fruits of our labours.
"But we won't let 'em," cried Billy, stoutly. "Didn't they leave us, the brutes, when they believed we should certainly be boiled or roasted? Didn't they steal our raft? Did you hear 'em say they'd make us fetch and carry for 'em if they caught us? We've done all the hard work and they'll come and enjoy it, will they? Not if I know it."
"We shall have to fight them then, Billy," I said.
"Well," says he, "and so we will; and we'll make some more spears and arrows at once."
"But some of them have got muskets," I said, "and bows and arrows will be poor weapons against them."
This made Billy look glum for a moment or two, but then his face brightened again, and he said, "I don't believe they've got many muskets. They were all put in the round-house, don't you remember, master? The Captain's orders. They stole one or two when we were all sixes and sevens in the storm, and I don't suppose they've got much powder and shot either, maybe none, for they're sure to have used some, and it's a long time ago."
This seemed to me very reasonable, and I thought that if we were within our walls we might defend ourselves very well for a long time against the men, even if they had a musket or two. But I wished we could in some way strengthen our defences, and my mind went back to my notion of cutting a moat around the hut, which would be of great assistance to us; but the difficulty of cutting it was no less than before, and I was afraid if we started it we should never get it done. Furthermore, the only condition of our making a successful defence at all was that we should not be taken by surprise as we had been this time, and I said to Billy that we must never go a voyage again.
"Well, and I don't want to," says he, "unless we can sail to England. I didn't like the look of them brown fellows with the painted faces, and did you see the sharks' teeth stuck in a ring round their hair? We're better off here, master; and here we'd better bide."
We Strengthen our Defences
We had been putting our place in order while we talked thus, and then we had our breakfast, eating indeed some of the food which the men had been preparing when we drove them away. And after we had done our customary morning's work—fed the pigs and fowls, gathered ripe cocoa-nuts, and so forth—we set to work at once to make some new arrows and spears, and bows and strings also, in case the others broke; and all the while we were doing this, Billy talked very bravely about the great fight there would be if the rascals came back. I said nothing to damp his ardour, but my thoughts were very busy with a part of the subject which he seemed not to consider, namely, what we should do if it came to anything like a regular siege. I did not doubt we could do much execution among the enemy from behind our walls if they stood to be shot at; but they could very well avoid this, and since there would be many of them against us two, they could strictly blockade us; and though so far as food went we could defy them for a long time, having our concealed stores below, yet the need for constant watchfulness, day and night, would in a short time wear us out. When I asked Billy what we should do in that case, he said, "Why, run out, and let 'em chase us; we could dodge them big chaps well enough, and I reckon we can run a deal faster." It was easy enough to show him that the hunted life we should lead would be most wretched and precarious; but he having suggested that we might escape set me on thinking whether we might not indeed elude the enemy, at least for such time as was needful to find some defence or shelter.
We had, of course, the means of descending into our cavern; and this was so well stocked with food that we might live there for a long time; but our disappearance would immediately be discovered by our besiegers (so I called them in advance), and they would know our whereabouts the moment they entered the hut. The cavern, therefore, could not be a permanent habitation. But it came into my mind again that we had never thoroughly explored the tunnel leading from it, nor found whether it had an outlet, though we suspected it had; and I thought that if there was such an outlet, or if we could make one, our case would not be so hopeless as at the present time it seemed. Accordingly, we determined to descend into the cavern, and make another exploration, going together, as we did the last time, both for the company's sake and for better security in case of encountering any danger. So we heaved up the covering of the shaft, and having made half-a-dozen torches, enough to last us for several hours, we went down, leaving Little John on guard, passed through the cavern, and came into the low and narrow passage.
Adventure in the Cave
When we arrived at the place where the second passage entered this from the right, we turned into it, and walked up an ascent, as I had done in the darkness, until the floor suddenly took a dip downwards, and then by the light of our torch we saw a considerable pool of water, extending farther than the light would carry. We debated for a little whether we should attempt to wade through this, and concluded that we would not do so until we had failed to find a way out in the other direction. Accordingly we retraced our steps, and went down the tunnel, until we came to the wider part where on our last visit we had seen water. The water was lower than it had been then, and we were able to go farther, and when we came to the brink of it, we heard very distinctly the sound of waves rolling in, so that we knew we could not be far from an opening to the sea. And, indeed, peering across the immense cave to which we had come, we saw far off a segment of blue sky, and knew that the object of our search was gained.
We stood at the edge of the water, surveying the cave by the light of our torches. We saw that there depended from its roof certain shining things like icicles, of rugged form and differing in length, which I have since learned are called stalactites; and, moreover, there were large boulders and masses of broken stalactites standing up out of the water. Billy gave a shout when he saw this, and cried that he would skip from rock to rock until he came to the mouth of the cave, and defied me to race him; but the torch I was carrying was now burning low, and I stayed to kindle another before going farther; and, moreover, I doubted the wisdom of such feats of agility, for it would be easy to miss one's footing and fall into the water, and if we both did it our torches would be wetted and we should not be able to light ourselves home. I had, indeed, just called out to him to come back, when a dreadful shriek ran through the cavern, and raising my torch above my head, I saw Billy scrambling up a tall and rugged rock that stood ten feet or more above the water, a good way from where I stood. He had dropped his torch, and I saw him but dimly by the light of mine, and could not discern any cause for his terror; but that there must be a very great cause I knew well, for Billy was brave enough. He continued to shriek and call, though his voice rang so in that hollow vaulted space that I could not at first make out any words; but having started to approach him when I heard his first cry, going from rock to rock as quickly as I could, I was presently able to see a number of long tentacles clinging to the rock on which he was perched, and others waving horribly above the surface of the water, as if some blind creature were groping for its prey. And even as there came to my mind the recollection of that loathly monster from whom I myself had barely escaped, and I stood as if fascinated by those hideous antic limbs, I saw the vast bulk of the beast appear above the surface, and rise gradually behind its tentacles up the rock.
Billy was by this time perched on the very summit of the rock, and when he saw the monster ascending towards him he let forth another dreadful cry which roused me from the sort of trance into which I had fallen. Grasping the torch with my left hand and my axe with my right, I leapt over the low rocks that stood between me and Billy, scarcely keeping my footing, and began to hack with all my strength at the shapeless mass, which made such a resistance to that poor clumsy axehead as a thing of leather might make. It did not appear that my strokes were of any avail, for the tentacles crept higher and higher; and looking up when I heard another scream from Billy, I saw that one of them was beginning to twine itself about his leg. And then all of a sudden, while I was bringing my axe down once more on the monster, Billy made a leap upwards, to catch at a stalactite that depended from the roof of the vault, not far from his head. He must have been pretty near beside himself to do what he did, for if he had caught hold of it he could not have held on long; and what did in fact happen was that the stalactite broke off with a sharp snap, and down came Billy and it into the water. I thought this might be the best thing that could happen, for he could swim like a fish, and the monster would take some time in letting itself down from the rock; but when Billy rose to the surface, and I called to him, I saw by his feeble movements that he must have been hurt, so I sprang to a low rock near which he had come up, and held out my axe for him to grasp, which he did, and so I got him on to the rock, though not without some trouble, it being scarce broad enough for both of us. And immediately afterwards I observed that the monster had left the big rock and disappeared into the water, on which I cried to Billy to be of good cheer, because I was sure my continual chopping had wrought some damage on the monster and maybe killed it. But the words were scarce out of my mouth when we saw, by the ruddy light of my torch, a tentacle appear above the water not three feet away. This put me in a shudder lest we were in a perfect den of the creatures, and I called to Billy to jump across the rocks, if he could, back to the entrance to the tunnel, so that he at any rate, being now the weaker, might be out of harm's way. His terror lending him strength, he gathered himself together and leapt from rock to rock as he had done before, while I seized upon the axe which I had dropped beside me when I landed on the rock, and chopped away in a kind of frenzy at the tentacles which were brandishing themselves, you may say, at several places around me. As soon as I saw that Billy was safe I gave up the contest and sprang after him, and I was never so thankful in my life as I was when I stood beside him at the end of the tunnel.
We were neither of us in any mind to linger there, lest the monster and his brood came to attack us, for we were now so terrified that we would have believed them capable of anything. This was the second time that we had been baulked of finding an outlet to the sea, and our experience had been such that we should scarce attempt it again. We hurried back through the tunnel, and had not gone very far when we had another alarm, for whereas it had been dry when we descended, there was now a little stream of water running down, which increased as we advanced until it became almost a rivulet. At first I thought that the plug had come out of the pipe leading from the lake into the shaft, but when we came to the junction of the two passages, we saw that the water, which was now above our ankles, was pouring out of the right-hand passage, and not from the one that led from the cavern. This eased our alarm, but we did not stay to consider of any attempt to discover the ultimate source of this little torrent, but hastened on until we were once more in our hut; and then we knew by the mighty pattering on the roof and all around that a very heavy rain was falling. Indeed, when we opened the door we saw that it must have been raining ever since we departed, for the ground was exceeding sodden, and the trench about the hut was half full of water, being scarce deep enough to carry off the drainage. Of course the rain had put out the fire which we kept constantly smouldering in the grate a few feet from our door, and though a hot meal would have been very comforting after our fright and the wetting we had got, we could not make one ready, because we had no dry wood in the hut, nor indeed did we care to light a fire in it, having no chimney to let out the smoke.
A Mystery Solved
It continued raining for two or three days, greatly to our discomfort; and we made up our minds to two things: first, to have a stock of firewood ready dried; second, to build ourselves a better grate, which we could cover in with pottery ware, and thus prevent the fire from being ever extinguished. During these days we observed, as we had done before, that the lake did not rise above the high-water mark, though the rain was the heaviest since we had been on the island; and when I sought once more to account for this, and remembered the torrent pouring down the passage, it came all of a sudden into my mind that I had the true reason of it. The passage, as I have said, rose continually from the cave inwards. Well, I guessed that its upper end opened into the side of the lake, but it then rose until its highest point was pretty nearly on a level with what we called the high-water mark, and after that descended again. If it was so, it acted as a siphon, the water not flowing down the passage until the lake rose to the same height as the highest part of the passage. When I tried to explain this to Billy he said it was all gammon, because if there was an opening from the lake into the passage the water would keep on flowing through until it couldn't help but run over. He could not in the least understand that water could never rise above its own level until I showed him by means of two tanks made of pottery, one large and the other small, and then he owned that I might be right, though he said it seemed to him like saying that a ten-pound weight wouldn't send up a five-pound weight if they were put in the opposite pans of a balance.
However, my discovery (supposing my reasoning was correct, and we could not prove it)—my discovery, I say, was of no practical advantage to us, indeed, rather the reverse, for it seemed to show that the tunnel from the cavern to the sea might be sometimes impassable, so that as a way of retreat from our hut it was doubly useless. When I pointed this out to Billy he said, "Never mind, master. We shall only have to fight all the harder inside, that's all," which shows how hopeful he always was. The only comfort I had was to think that our fears and anxieties might never be justified, and that Hoggett and his crew would never more visit us.
