Perseverance Island

I had always with me in the boat, two strong, sharp harpoons with long, seasoned, wooden staffs, in complete order, and also a lance and knife. To the harpoons was attached a raw-hide rope, some fifty fathoms in length, and with this I made up my mind to strike the serpent if I could get the chance. To the end of the raw-hide rope, I attached a wooden buoy, and, thus armed, I started the goats, and headed the boat in the direction the monster had taken but a few moments before, and in such a leisurely manner. I had not gone far before I saw the end of his tail coming in view, as he lay stretched upon the sandy bottom. I lowered the boat till I floated about eight feet above the hidden form, and, plucking up my courage, steered forward over him, with his huge body for a guide. As I arrived near his head I stopped the goats, and let the boat drift, the tide luckily being in the direction that I desired to go, that is, what there was of it, which was very little. As the head came slowly into view, I saw that the monster was engaged in quietly crunching in his horrible jaws a fish of some size, that he had evidently just caught, and, upon which his attention seemed to be fixed. The moment was propitious, and, as the boat slowly drifted, not eight feet over the head of the terrible creature, I stood with the harpoon in my hand, and deliberately drove it downward with all my might through his head, just abaft the eyes.

I did not stop to see the effect of my blow, but immediately tumbled into the water, as fast as possible, several of the large stones that I used on the shelves for ballast, so as to ascend at once towards the surface, casting overboard at the same time the line attached to the harpoon, with the buoy at the end. Relieved of the ballast, the boat commenced to ascend instantly and rapidly, but none too soon, for, as it was rushing towards the surface, just below me came the sweep of the creature's terrible tail in its death agony. If I had been struck with it, it would inevitably have capsized my boat, and perhaps have killed me, or, at least, left me to swim ashore to the island, distant some miles, or else be drowned; but, luckily, the blow missed me; the ascent of the boat was so rapid, the very moment I kicked and threw over some of the ballast. Having risen as near the surface as possible, I rigged my pump and ascended still further, and then, setting up my tripod and shipping my air-boat, I soon had air enough to rise completely above the surface, and to open the manhole and look about me. Of course, my first glance was to discover my buoy. Yes; there it lay, not fifty yards from me, without any motion, except what it received from the waves upon which it floated. I could hardly credit that at the other end lay the sea monster, transfixed through the brain with my trusty harpoon; but such, I felt sure, was the case. The mark had been too near and quiet for me to fail, and I had with my own eyes seen the iron driven in up to the staff through the centre of its head. I longed to find out the state of affairs, but did not dare to descend for fear of being caught in the folds of the dying monster. I steered for the floating buoy, and, getting hold of it, by means of a boat-hook thrust out of the manhole, I pulled it towards me, and gathered in all the slack line, till I could feel that I was pulling direct upon the harpoon. No vibration came to me through it, and I could slightly raise the weight evidently attached to the other end, but I was afraid of possibly drawing out the harpoon, so I did not attempt much in this direction; but, being assured that the creature was dead, I finally mustered up courage to descend and look at him. As I came near the bottom, I stopped the boat and advanced in the direction that the line from the buoy trended in. Yes, there he was, dead as a door-nail; but his whole body, that had so lately been stretched along the bottom, was coiled up and around the staff of the harpoon, which had pinned the head to the ocean's bed. I came near enough to see that the creature was really dead, and then, rising to the surface, I made all haste for Stillwater Cove. Arriving, I got up steam on the yacht, and made all haste back to the buoy, towing the submarine boat behind me. When I got upon the ground, I descended in the submarine boat, and, by means of ropes, and pulling and hauling in each direction, I got the body of the serpent somewhat straightened out and the head clear. Around the neck I fastened a good, strong, rawhide rope and attached the buoy rope to it. I then, at a distance of some thirty or forty feet from the head, lashed to the back of the creature my air-boat, to sustain that part somewhat, so that it would not drag upon the bottom. I then arose to the surface and went on board of the yacht, and took the buoy rope to the balance-wheel in the engine-room, and hove the head of the monster nearly to the surface; the water sustaining it, so that it was not very heavy. I trusted to my air-boat to help sustain the remainder of the body, and, thus accoutred, with the submarine boat towing far astern out of the way, I headed slowly for Stillwater Cove, towing my prey behind me. When I arrived at the opening of the cove I drew the carcase as far as possible, by means of the steam yacht, on to the sandy seashore, where the tide would leave it out of water when it receded. I then liberated my goats, and moored the boat in the harbor near by, and, taking my pets on board, after anchoring the serpent safely, steamed towards the Hermitage, where I landed them, and took on board some empty barrels and knives, hatchets, and saws, to dissect my sea monster. When I arrived back the sea had already fallen so as to leave the head and at least twenty feet of the body high and dry. After the tide had wholly gone down, I measured the monster, and these were the dimensions. Taking my measure of a fathom as a standard, the creature was twenty-two and one-half fathoms long, and, at its largest girth – about two fathoms below the neck – over one fathom and a quarter in circumference. It is difficult to describe the monster, but I will try. The head was at least eight feet long, and the extent to which the mouth could be opened over six feet; the gullet was small; the teeth numerous, but small; the nostrils large and prominent; the eyes fully six inches in diameter, and with an expression that, even now that the creature was dead, I could not stand when I looked into them. In the stomach I found only small pieces of different kind of fishes, and, by the smallness of the teeth and gullet, I am inclined to believe that the creature is naturally quite harmless, like most of the mighty animals of the earth, – as the sperm whale, elephant, etc., which never attack anyone unless disturbed. Beyond the head, and, for a distance of some ten feet, grew a sort of mane, formed of pendant tissues of flesh some five or six feet in length, exactly like those to be found on the sides of the mouth of the Mississippi cat-fish or smaller horn-pout. Towards the tail, and some distance from it, was an adipose fin, that was at least a foot high and fifteen feet long. The skin of the creature was of a mottled greenish hue, rough, and discolored, something the color of the shell of a very young crab, and at least a good quarter of an inch in thickness. Having taken all the dimensions of the monster, I went to work and cut off his head, and left it purposely where the fishes, lobsters, etc., would feed upon it at high water, so as to in time preserve its skeleton when all the bones were completely articulated. The remainder of the body I skinned in sections, at different times, and was glad to roll the rest of the body into the current of Stillwater Cove, to be carried out to sea.

I have enough on hand, at the time of writing this, to prove to any one that I have both seen and captured the veritable sea serpent; for, as I sit in the Hermitage, the whole skull, with jaws, teeth, and part of the vertebræ attached, is hung up near me, and below it a circular piece, nearly four feet long, of the hide of the animal at its greatest girth. The frontal bone of the skull, which is not very thick, is broken where the harpoon iron entered and caused immediate death. With this exception the whole specimen is in complete order; and I have also a sketch of the animal drawn upon parchment, from actual life, taken by myself before he was at all mutilated or cut up.

I hope that this truthful, consistent, and convincing recital will close forever this mooted question; for there is a sea serpent, and I have been able to capture and preserve one of his species.

CHAPTER XXIX

Make a Balloon and Flying Machine, in which I make a Successful Ascension.

My thoughts turned wholly now upon means of defending my vast treasures in case of invasion, and devising ways of escape from the island. As to the former, I overhauled all my artillery at the different points, increased my stock of gunpowder, and had each cannon well supplied with ammunition. I also perfected my battery at Stillwater Cove, and kept the armament on the walls of the Hermitage in excellent order. Not content with this, I went to work in the foundry and turned out several cylinders, similar to the one I had exploded the sunken wreck with, which I fitted with flint and steel, ready to be filled with powder; in short, a species of torpedo, which I had fully determined to take into the submarine boat and explode beneath the bottom of any hostile vessel that should dare to attack me, so much had the acquisition of vast riches changed my disposition. I felt that any vessel approaching and anchoring would be at my mercy; for in the night-time I could approach her, wherever she might be anchored, unknown to anyone, and, attaching one of my infernal machines, send her to the bottom with all on board. I do not say that I should have done this, but I was prepared for all emergencies, and determined to defend my treasure to the last. For means of escape I turned my attention to ballooning, – a subject which I had thought much about, but heretofore had done nothing in that direction. For several years I had been quietly gathering in all the dried pods of milkweed, floss, or silk that I could find, – and large spaces of the island were covered with it, – determined at some time to weave me some kind of cloth or silk from its fibre. I now commenced seriously upon this work, and took hold of it in earnest. It would take too long to relate how many changes I had to make in my loom, which I built of cast-iron, to be moved by water-power, before I could get it to work at all; but I had the theory all correct, and it was only practice that I needed to make cloth. The machine for spinning the floss into threads took me the longest time, but I finally accomplished it. After a while, and with many failures, I commenced to turn out from my loom a sort of cloth, about a yard wide, which was very strong, flexible, and light, but of an uneven surface, on account of the irregularity in the size of my threads, and fuzzy, like coarse flannel; but for strength and practical use I found the material all that could be desired; and, having tested it, I set carding and spinning wheels to work daily to procure thread for my loom. After making some hundred yards of this cloth, I stopped all the operations to experiment in another direction. In my boyhood I had seen balloon-ascensions made by filling the bag with a gas, created by pouring sulphuric acid upon iron or steel filings in this manner: Several old hogsheads were brought upon the field where the ascension was to take place, and into each of them was poured a quantity of iron filings, scraps, etc., and upon this was poured sulphuric acid; the casks were then headed up, and through a small orifice the gas engendered was led by a pipe from each to the balloon, which was thus inflated. If I could make this gas and successfully inflate a small balloon, it would then be time enough for me to advance with my clothmaking for a large one. I easily ascertained from my book how to make sulphuric acid. And this is how I did it: I got together a quantity of sulphur or brimstone, and setting fire to it in a closed vessel, with just enough draught for it to burn, I led the fumes into a closed vessel of water through a short funnel, where, combining with the water, I had at once sulphuric acid. To test this I tackled my friends the dog-sharks, in Stillwater Cove, and obtained several bladders, very thin and light, just suited for my purpose, which I blew up with atmospheric air, and allowed to dry perfectly in the sun. When they were in proper condition I placed in one of my porcelain jars a few handfuls of iron and steel filings, and poured upon it some of the sulphuric acid that I had made, and then lashed the neck of the bladder to the orifice of the jar. I watched my experiment with subdued excitement. I felt sure that I was right in theory; would the thing work in practice? I had yet to see. After leaving the bladder on for a considerable time, I drew a string around it perfectly tight so that no gas could escape and released it from the jar. With fear and trepidation I loosed my hold upon it, and in one moment it shot up into the sky like a rocket till it was nearly beyond my sight, when it disappeared in a northeasterly direction before a strong wind that was blowing. I was as pleased as a boy with his first toy-balloon, and, like a child, I let off several of these bladders as fast as filled with gas, perfectly fascinated to see them ascend and then disappear in the blue ether.

Here was a means at once of sending up daily messengers to all parts of the world, stating the latitude and longitude of the island, and asking for rescue. Aye, but there was the rub; without my treasure how gladly would I have seized upon this method of letting my captivity be known, but with it I had become a coward. I wanted to escape, and did not dare to ask anyone to aid me. The knowledge that I could ask was, of course, a satisfaction, but as yet I did not dare to risk it, and put the matter on one side for further meditation at some future day. Finding that my theory about the gas was correct, I went to work again upon my clothmaking, and worked hard at it nearly six months, when I had sufficient quantity for my purpose, which was to make a balloon of large enough size to make an ascension in myself. I did not have any foolhardy idea of leaving the island in a balloon and landing I knew not where, but I was determined to make a series of experiments in several directions, that had been running through my head for years before, and to see what they were worth. In the first place I went to work and made a balloon, in the shape of an immense cigar, of the cloth that I had manufactured, which was some thirty feet long, and ten feet in diameter. My theory was this. In all balloon ascensions navigators heretofore had only been able to fill a sack with gas, and to ascend into the air, and descend by allowing the same to escape, in other words, to have but little control of the machine except to ascend and descend, and this in a limited degree. I had often noticed that, in the severest storms, seabirds would remain poised in the air without moving a wing, facing the wind, and yet not recede before it, but by a slight motion of the wings, not up and down or a stroke, but a sort of elevation of the body, dart dead to windward against it. I had also noticed that, if a tin plate was thrown into the air against a strong wind, it would often, if at the right angle, increase its speed greatly after leaving the hand, and dart into the wind's eye with extreme velocity. Hence I thought that a balloon could be made to tack in the air exactly as a boat tacks in the water, except that the motion of tacking should be perpendicular instead of horizontal. Suppose that a balloon, cigar-shaped like mine, was poised in air at an altitude of one thousand feet, and that at each end of the car was arranged a light but large horizontal flat surface, exactly like a barn door laid upon the ground, with its hinges attached to the car. To advance against the wind why not elevate the one in front and depress the one in rear to the right angle, or till they were filled as we should say of sails, and then advance into the wind's eye, increasing at the same time the elevation, as the tin plate is forced forward; and, having made a tack upward and forward, why not elevate the rear screen and depress the front one, and descend towards the earth at an angle, still eating our way to windward, and when near the surface reverse the action and mount again heavenward, but still to windward. Besides this, why should not my balloon be filled with gas till it would lift myself, the screens, the car, and all its apparatus within one or two pounds. That is to say, to have just enough gas in the balloon, not to raise the apparatus, but to so nearly raise it that another person, if present, could lift the whole in his hand; practically to reduce the weight of my body to that of a good sized duck; then with small wings, not immense cumbersome ones, the same size that would raise a duck, I ought to be able to raise myself, and sail in the air. Could it be done?

After I had made my balloon bag I covered all the cloth and the seams with a fine varnish that I made from the resinous trees of the island. This part of my task caused me little trouble. Having finished it I went to work upon my car and its appurtenances, which I made almost wholly of small cane, very strong but very light. I made also two immense screens or fans, which I fastened to either end, so that they could be elevated or depressed, and covered the light framework with cloth. Underneath the centre of my car was hung vertically a propeller, also made of cane, and the blades covered with cloth, and on each side a fan wheel some six feet in circumference and two wide. The shaft of these fan wheels and propeller was brought into the car, and, by a series of bevelled gear made of the lightest iron possible, was connected with a treadmill for one of my goats, motion upon which would give over five hundred revolutions per minute to the fan wheels and propeller. In this car I also fixed a jar of iron filings and a bottle of sulphuric acid to make gas, if necessary, to replace that which would in time leak out of the balloon if long inflated. I also provided the machine with sand ballast in case I should need it to keep up the equilibrium in case the gas should escape faster than I expected, when I could keep my elevation by discharging it. After this was all arranged, the next thing was to make the experiment.

I have always thought that great advancement has been made in all the arts of navigating the ocean on account of the ease and safety with which experiments can be made, but to experiment in the air one must go into the air, and if the theory does not work in practice, down he comes, perhaps a corpse, on to the hard earth, whilst a capsize in the ocean in experimenting is nothing. Now I had made up my mind to go up in this machine, if possible, but I had also made up my mind that I would go over the water and not over the land, so that if anything did not work, I should only take a cold bath and nothing more; besides, by my theory, I need not go high, and could keep a few feet above the surface of the sea, and if disaster occurred I could swim ashore. I put my goat daily upon his treadmill and worked my machine theoretically till I was satisfied with it. I then made myself a nice life preserver of fish bladders, and put into the car some few provisions and water. The next task was to launch myself properly into space without any disaster. To enable me to do this I went to the mouth of Stillwater Cove and erected a sort of wharf from the shore out into the water at nearly high tide, about four feet wide, upon which I could rest my car with the fan wheels hanging over each side and the propeller clear underneath, the wharf not being planked, but consisting of a few uprights and cross pieces only.

I carried here all my utensils for making gas and had everything prepared for a start. I needed in the first place a day with but little wind, but what there was to be from the southward so as to blow me off into Perseverance Bay when I should start. After some waiting, such a day came and I hastened to take advantage of it. In the first place I took the canoe in tow of the yacht, and anchored it nearly a mile from shore in the direction that the wind blew, so as to be able, perhaps, to reach it if I should find myself too far from land in case of disaster. I then returned and went to work filling my balloon with gas. This I did on shore, till I had sufficient in the balloon to make it steady, when I conveyed it over the car upon the wharf, where I attached it by its numerous cords, and then connected it again with the orifice of the pipe that was supplying the gas. I had before in a rude balance ascertained my own weight in sand-bags, and these I had in the car to represent myself. I put the goat on the treadmill, all harnessed in, ready to start at a moment's notice, and in fact I did start him before the balloon was very buoyant, to see if everything was working right. I walked about the car, lifting it once in a while to see how buoyant it was. I should have said that the propeller had been changed from my first idea, as had the paddles. The former was so arranged as to work vertically, and motion from it ought to force me into the air, whilst the latter were arranged in the form of two lateral propellers, I having bethought myself in season that a revolving wheel in the air would not force me in any direction, whilst a propeller would. The time finally came when the car and all its appurtenances weighed only a few ounces in my hand, in fact nearly ready to take flight of itself. I then cut off the gas and placed myself in the car and commenced quietly emptying over the side the sand bags that represented my own weight; and these being exhausted, I boldly threw over at once two bags weighing nearly or fully twenty-five pounds each, as I was determined to start clear and rapidly from my resting place, knowing that I could easily descend by letting out a very little gas. The effect was instantaneous, and I arose rapidly and commenced floating slowly out over Perseverance Bay; but I had no desire to go high, and I opened the throttle valve at the very moment the balloon started, and at the height of about one hundred feet it was already commencing to slowly descend, which I allowed it to do, till it was about twenty-five feet above the water, when I threw out of gear the lateral propellers and started the goat; the effect was instantaneous in checking the descent, and the vertical propeller was forcing me upward with magnificent speed, in fact I found myself quite too high for comfort before I bethought myself of stopping the goat, which being done I commenced again to descend, but quite leisurely, being very evenly balanced in the air. When I came near the water, I set the vertical propeller again to work and arose heavenward. All this time I was drifting slowly out seaward over Perseverance Bay, and I thought it time to try my lateral propellers; so, setting the gear at once by a handset, I put on all goat power, being at a distance of some fifty feet above the water, as near as I could judge. Everything worked admirably, and I saw that I was rapidly increasing my speed seaward. When I descended too near the ocean I put on the vertical propeller, but I noticed that the lateral ones sustained me as well as forced me forward. I soon ran past the place where the "Fairy" was anchored, and I had now to try my last experiment. By this time I had become at ease in my car, and began to feel as safe and secure as in the submarine boat. By stopping one of the lateral propellers I soon had my balloon turned round and facing the wind, which was at this elevation and out to sea, rather more than I had reckoned upon. As the point of the cigar-shaped balloon came to the wind, I put on the vertical propeller and ascended higher than I had ever yet been, and then, depressing the forward screen and elevating the rear one, I made a dive in a slanting direction towards the ocean; and here I had like to have been shipwrecked, for my car commenced descending with such rapidity that I had scarcely time to reverse the action before I was in the ocean, but happily, by starting the vertical propeller I saved myself, and found the car going just as rapidly upwards.

I had solved the problem. I was tacking to windward in the air. I was utilizing the action that causes a boomerang to take the seemingly erratic course it does through space. Having tacked a few times I stopped in mid-air, and, as I had evidently lost some little gas, threw over a small amount of sand, till I sailed again almost in equilibrio. I then put on all the speed of my lateral propellers, and found that I could stem the wind, and that I was approaching the shore. By the action of either one propeller or the other I could change the direction of the car at will, and was enabled to hover over the very wharf whence I started, and to land upon it with a shock no greater than sitting down upon a hard chair.
