Perseverance Island

In five days' time I found myself in possession of over twenty pounds, I should judge, of good gunpowder. I found by my book that it was not at all peculiar to find potassium as I had found mine, and further, that to purify it I needed to mix it with equal parts of wood-ashes, and then add water and allow it to stand a few hours, and then draw off the lye and place it for three days in the sun, in shallow vessels, to evaporate, and then boil down what was left, to procure absolutely pure saltpetre, all of which I did. And when I had manufactured my powder, and observed by experiment that it was much sharper and louder in explosions than before, showing the improvement of purifying the saltpetre, I placed the whole lot in my goatskin bag and started for the mountain. Arriving at my excavation, I looked about to see what I could do to make my explosion effectual and do the most good. By examination, I found that there was quite a space between the two inner boulders that obstructed my way, and a sort of vent-hole that led, I knew not where. Into this I commenced to pour my powder, and used up over two-thirds of all I possessed before I saw any result. Finally, the crevice, just as I began to despair and thought I had thrown away and lost it all, showed that it was full by refusing to receive any more. As soon as I noticed this, I knew that I had an excellent chance to make a good blast, and I therefore pushed in the powder in sight, and was able, by shoving it downwards, to add at least two pounds more. I then carefully inserted a strand of manilla previously soaked in wet powder, and dried, into the mouth of this crevice, and well down into the powder; I then stuffed the whole with small pebbles and moist earth, and finally placed quite a large rock against the vent, and, with a prayer for success I lighted the fuse and retired to a safe distance to watch the effect. As before, it seemed as if it would never ignite, and I waited and waited, taking care to be well distant and well sheltered behind a large boulder, till finally, with a dull, low, smothered noise, the charge exploded. I was disappointed, and was afraid that my powder was too weak or ill-made, but when I arrived at the spot I was amazed at the execution that had taken place: the whole roof had been uplifted and thrown open, and the boulders that had resisted my further entrance cast to one side, and the whole side of the mountain pierced and opened in a wonderful manner. I dashed into the opening that had been made, and the first fragment that my hand closed upon was pure iron ore. I was like one mad with joy. I acted as insanely as I had once or twice before since landing upon the island, and danced and sang, and ended by sitting down and bursting into tears. Upon further examination I was inclined to believe that the whole mountain was composed of iron, and that I only needed to pierce the crust in any direction to get the precious metal. My discovery lay just about one mile from my home, and quite accessible.

I found that the blast had brought to view quite a large surface, on one side, of my saltpetre, whilst further to the southward appeared the iron ore in masses that I could pry out with my pickaxe. After having feasted my eyes long enough upon my treasure, I started down the mountain, smoothing the pathway wherever it was rough, and opening up a way for my team and sled to bring down the ore to the hermitage.

I absolutely saw no end to the improvements that I could make now that I had iron to work with. I could do anything within reason, and make anything I chose to make. A thousand and one schemes of escape by its means rose up before me. If at this moment I could have had the companionship of my fellow-kind, I should, I think, have been unable to ask any blessing to be added to my lot. Here was I in evidently one of the finest climates of the earth, with everything about me even now to sustain life, and with many of its luxuries, and with the foundation laid for many more.

Upon a close examination of the specimen that I had brought away with me in my bag, home to the Hermitage, and by consultation with my book, I felt convinced that I had discovered what is called magnetic iron; that is, iron ore that is most universally dispersed over the earth. The action of the compass added to this belief, and the limestone formation was exactly fitted to this kind of ore, which is the same as is generally called the Swedish iron ore, one of the best-known irons in the world. The color was a sort of black iron shade, and the ore brittle and attracted by the magnet of my compass; whereas, if my iron ore had been hematite it would have been of a dull steel color, and probably without magnetic properties.

How I revelled in what I was going to do. First, I was to build my kiln and put the ore through that to purify it of sulphur, arsenic, water, &c., then to a blast furnace, to be heated with a flux of limestone and coal, and in the melted form run into pigs in the sand of the smelting-room. Once in this melted form I could make, from moulds, chisels, axes, hatchets, plane-irons, and saws, by a treatment of the melted iron ore. By means of blasts of cold air I could change the whole mass into Bessemer steel. With the tools I have named, in my hand, I could go to work at once to erect a sawmill on Rapid River, near the Hermitage, and with the greatest ease saw out all the plank I should want for any purpose under the sun. Then my thoughts strayed away to nautical instruments, some kind of a quadrant, then the latitude and longitude of my island, and then a chart on Mercator's projection from my Epitome; and then turning-lathes, iron boats, electric wire, gunmaking, steam engine and propeller boat, torpedoes for defence, and all the means to escape from this miserable solitude. All these things, I say, ran through my head like wildfire. Nothing was now impossible. I had got my genie, and I was determined to make him work. The weather was getting cooler and cooler, and one or two storms had already warned me of the approach of winter. The leaves began to fall, and the whole island commenced to look dreary and forsaken; the grass, however, retained its freshness in a remarkable degree.

It was in the latter part of May that I discovered my iron ore, and I knew that this was the same month comparatively as November would be in the northern hemisphere; and although there had as yet been no actual frost, much less any ice or snow, yet I saw signs, not to be disregarded, that the weather would be more severe and colder before the spring days would come, and yet evidently I had not much to fear from a very great degree of cold, as my theory concerning the climate had so far been singularly correct. I commenced, therefore, at once, without loss of time, to collect my ore by means of my team of goats, and transport it from the mountain to Rapid River. I did not bring it over as I had the coal, for I determined to erect my blast furnace and kiln on the further side, and opposite to my home, as being more convenient in many respects.

I worked hard myself, and worked my team hard, in bringing to Rapid River both the iron ore and coal, and also quite a large quantity of the potassium, which I carefully took into the hermitage till I should need it to make more powder. It did not take very many trips, however, after all, to get the iron ore that I should use during the winter, at least, but the coal to smelt it took me longer. After I had gathered all of each that I thought I should need I gave my goats a rest, and set to work to make arrangements for my smelting-furnace, kiln, and smelting-room, and how I proceeded I will now go on to relate.

CHAPTER XV

Make a mould for bricks. Build a brick-kiln and make bricks. Build a smelting-house, blast-furnace, kiln for cleansing ore. Meditations. Build water-wheel and fan-wheel, and set my machinery for an air-blast to reduce the ore.

In the first place I went to work, and with my knife and hatchet fashioned out two quite smooth pieces of wood about four feet long, three inches wide, and perhaps one inch thick. I smoothed these on one side with a great deal of care, and finished them off by means of dry shark's skin, which stood me admirably in place of sandpaper. I placed these two slips of wood parallel to each other, about four inches apart, and fastened them in that position by means of blocks of wood of the same size and thickness, placed between them at equal distances of about six inches, which subdivided the whole into eight equal compartments, fastening the cross-pieces in by means of hardwood pegs driven into holes in the side, made by a red-hot nail. When my labor was finished my affair looked like a set of pigeon holes, such as are used in an office, except they were open on both sides and had no back, and each compartment was four inches wide, three inches deep, and six inches long. This was an insignificant looking thing in itself, and, except the smoothing of the inside in all parts, was not a labor of any great magnitude, and yet by means of this instrument I intended to make a great stride forward in civilization. The thing that I had made was a press or mould for bricks. I do not know the technical name, but I knew that if I placed this instrument upon the level hewn side of any fallen tree for a table, and filled each compartment with clay properly moistened, I should at each filling and emptying turn out eight equal-sized, unburned bricks, all ready for the kiln.

To enable me to prosecute this work I moved for a few days to the landing-place, where clay in abundance was to be found, and where my old hut would give me shelter. When I say I moved there for a few days I should say that I came home to the Hermitage every second day to care for my flock of goats and look after my household cares. Upon my arrival at the clay pits I soon set to work, and my clay was so pure that I had little trouble in moulding it; and, after having fixed a smooth plane upon a fallen tree as a table for the bottom of my mould, by levelling the same with my hatchet, smoothing with my knife, and finishing with my shark-skin sandpaper, I set to work moulding, getting my water at a short distance inland from a boggy piece of ground abounding in springs, which existed right under my nose, a little to the left, when I was so anxiously distilling water upon my first arrival at this very spot. I transported this water, by means of gourds and my canister, easily, to the clay pits, and soon had a fine array of bricks, the moulding being simple, and I found I could work quite fast; and by means of my knife and a sharp clam-shell or two, and with a large mussel-shell for a shovel, I had no difficulty in filling the mould quickly and trimming off all superfluous clay very rapidly. As fast as I finished one set I dashed the mould over with fresh water, so that the next lot moulded would slip out easily after being carefully pressed in. As fast as I made the bricks I allowed them to lie for a day or two in the air till they hardened, and then commenced to pile them up in shape to be burned and perfected into bricks. As a boy I had often examined brick-kilns, and I knew that I must make, or rather leave, a sort of oven under them, and, throughout the whole pile, apertures through which the flames and heat would penetrate so as to bake the whole mass. I built my kiln with care and on the above principles, and in less than a week had a goodly array of bricks all built up in complete form. I then with my goat team drew to the kiln all the old dead wood I could manage, and with my hatchet cut it into suitable lengths to be thrust into my ovens, for I had three of them in the whole pile, and with great glee set fire to them all one evening, and saw that they had a good draft and burned fiercely. I worked like ten men to keep these fires perpetually going, and, prepared as I had been in the commencement by laying in a large supply, I, with the aid of the team of goats, was able to keep up with them and feed them regularly. I do not remember now how many days I burned these bricks, but it was very easy to examine them and see when they were sufficiently hardened and burned; and when they suited my eye, and I experimented upon several by breaking them open, I let the fires gradually go down, and found myself in possession of a nice stack of bricks, fit for any purpose. These, as they cooled, I transported in the canoe to the landing opposite to the Hermitage, where I had determined to arrange all my appurtenances for smelting the iron ore.

In the first place I commenced a house or workshop, about twenty feet long and twenty wide, by building up walls of stone, as I had done for my Hermitage, but in a much rougher and coarser manner, without foundations, and very much lower, not over six feet in height. Over this I erected the usual bamboo roof and rushes for thatch, with one opening for a window, and one for an entrance, in opposite sides. The floor of this room I covered with pure white sea-sand for one half, and the other half with soft, pulverized, dry, clayey loam that would do me for castings. In one end of this smelting-house, as I called it, with the feeding-place outside, I built, in an aperture in the wall left for that purpose, a solid blast furnace of my bricks, which I lined with my pottery cement, and made in every way complete to receive the ore and smelt it. This was to me, except the manual labor, boy's play. The opening for the fused iron was within the smelting-house, and I could run the ore on to the sandy floor in channels made for that purpose, and thus procure my pig iron or Bessemer steel as the case might be. In this blast-furnace I left several channels to be connected in some way with a blast of cold air, for without this blast I could not of course expect to smelt the ore. To improve the draught, and to have Nature help me all possible, I built the chimney or cone of the blast furnace at least twenty feet high, of bricks, tapering the same in a cone form from the base to the apex. I worked upon this matter like a beaver, and felt well satisfied with my work when it was done. My smelting-house stood quite near to Rapid River Falls on the further side, for I had foreseen that I should have to use some power to get up speed to move some kind of a fan wheel, and I knew that I could only do it by means of water, and had therefore, for that very reason, placed the house near to the bank and had built the blast-furnace on the end of the house nearest the river.

After finishing my blast-furnace completely I left it to dry and harden, and set to work at my roasting-kiln, on which my ore was to be first purified and cleansed. This was comparatively an easy affair, and was made wholly of bricks, underneath which large fires could be built, and through the numerous interstices the flame would reach the ore placed upon the bed above; the flame, after passing through and over the ore, to be carried out at the other end of the bed by means of a brick chimney about twelve feet in height, high enough to give a good draught.

As soon as I had my kiln done I commenced drying it by lighting a fire under it, and found that it had a good draught and would answer my purpose admirably. I then went to work again with my team of goats, and dragged near to the smelting-house all the dead wood – and there were large quantities of it – that I could lay hands upon, that was anyway near or convenient. Being now in the month of June, I found the mornings often quite snappishly cold, and was glad of a little fire often in my home. But I worked so hard in these days that I scarcely had time, after finishing my supper, to smoke a pipe of tobacco before I was ready to throw myself upon my seal-skin bed and fall asleep. In these times I worked so hard and persistently that I often cooked enough corned meat to last me a week at a time, and could always draw upon my stores of salted fish and smoked salmon, and goats' hams, vegetables, etc., whenever I needed them. Of course many days I was unable to work in the open air on account of rain and storms. Those were the times that I took to improve my clothing, patch up my moccasins, and make up warm skins for the cold weather; look after my little flock of goats, which often strayed away short distances, but by being careful to feed them each night regularly on a little delicacy of some kind, mostly sweet potatoes, they always came back to the shelter of a nice warm shed that I had constructed for them near my home, made on exactly the same principle as my hut at the landing-place.

It would take too long to enumerate the various little articles that I had gathered around about me, and how perfectly my mind was at rest on the following subjects: First, that I could not suffer for want of food, for I had enough and to spare of everything; amongst many others the following principal ones, – dried goats' flesh, jerked goats' flesh, smoked goats' flesh, smoked goats' hams, wild pigeons, eggs, fresh fish for the catching, smoked and salted herring and salmon, sweet potatoes, cabbages, turnips, beets, etc., vinegar, wine, salt, milk, etc. Second, that I had a large quantity of nice skins, both cured and uncured, of seals and goats, to last me a lifetime; with fuel, light, and covering against all contingencies, and tobacco for my solace. Third, that I felt confident and perfectly satisfied that the island was uninhabited and unknown, and I went to sleep each night without fear of being interrupted on the next day. My nerves had wholly regained their tone, and I was grown strong, rugged, and hearty, whilst my experiments with my iron ore and my hard work upon the smelting-house gave me the necessary incentives to keep me from thinking of my own sad fate. I saw such a future before me, could I have iron in all its forms ready to my hand, that I was kept in a state of excitement just right for my temperament, and was restrained thereby from gnawing at my own heart with bitter regrets which would avail me nothing. I do not mean to say that I did not have bitter and dreadful moments of despair and utter hopelessness, but these occurred usually in the evening when I felt my loneliness the greater than when I was at work in the open air. But I began to dispel this even by giving another current to my thoughts, making my pet goats go through their little series of tricks to amuse me and draw me away from myself. A good smoke at my pipe, and a glass of quite fair claret wine used often at these times to freshen me up and dispel my mournful thoughts. When these would not work I used to seek oblivion from my thoughts by plunging into my "Epitome" and studying out some problem that would aid me in, at some future day, fixing the latitude of my island, or else amused myself by reading something from my book of useful arts and sciences that might be of service to me some time.

Up to this season of the year no snow had as yet fallen, but ice had skimmed the little fresh-water pools outside of the main river, and some few nights had been cold outside; but, thanks to God who had been so merciful to me, I was warmly clothed and housed, and had nothing to fear from wind or weather.

During some of the stormy days I puzzled over the problem of how I was to get blasts of air forced into my furnace. And this is how I did it eventually. I cleared away a small portion of the fall of Rapid River, so that the water rushed with great force through a sort of flume of about four feet in width and three feet deep. I secured and regulated this floor by means of a series of gates and pieces of wood that I drove into the soil on either side. I procured them by cutting a tree, about twelve inches in diameter, into sections of about five feet in length with my hatchet, by infinite labor, and splitting them with hard-wood wedges into long rough clapboarding or scantling about an inch thick and I had no time to smooth them, but had to use them as they came to hand, rough from being split with the wedges; but as the wood was straight-grained I got quite a quantity of very fair pieces of board that suited my purpose, although not smoothed. I drove these, as I have said, into each side of the flume in the dam to protect the sides from being washed away, and arranged a sort of gate so as to keep all water from passing through when I so desired. It was a bungling sort of a job, and not very strong, but answered my present purposes quite well. I then went to work upon my water-wheel, which I intended to hang in this flume, and, by opening the gate above, allow the water to flow down upon it with great force and turn it, so as to obtain motion, and power to which to connect pulleys and wheels on the land side upon the axle of the wheel. I studied long over the formation of this wheel, and finally constructed it by taking for the axle a smooth, strong limb of a hard-wood tree, about four inches in diameter, and apparently perfectly circular in form. From this I stripped the bark, polished it with shark's skin, and cut it off so as to leave it about seven feet in length. I then, by means of rawhide and willow withes, fastened, at right angles to this axle, light but strong arms made of cane, extending about three feet in each direction from the main axle. These I again strengthened by means of crosspieces parallel to the main axle, which I bound across the arms, and over these again lighter canes yet, crossing the whole fabric from the extremity of one arm to the base of another, till I had a framework of a wheel, light and fragile to be sure, but very tough and well bound together, and each withe and rawhide string set well taut and securely fastened in real sailor style, – and sailors can make immensely strong articles bound together only with string, the secret being that they know how to make each turn do its work, and how to fasten the whole securely. I sunk into the ground on each side of the flume a strong post of wood some eight inches in diameter, each ending at the top in two natural branches, or a crotch, like the letter Y, which I smoothed out by means of my knife and fire so as to receive the axle of my wheel and allow it to revolve in them. These posts I set in the ground very deep and very securely, and battered down stones around their foundation, and braced them also with other stakes driven into the ground near to them, at an angle, and lashed securely to them. Upon my framework of the wheel I tied on, with rawhides, slats or "buckets," as they are called, of my split clapboarding, to be acted upon by the water and cause the wheel to revolve. Outside the axle, upon the shore side, I fitted a wheel of cane, about three feet in diameter, constructed in the same way as the main wheel, but not more than six inches in width. This was to receive a belt to communicate the power and motion of the water-wheel to a series of pullies that I was yet to make. After getting the wheel in place, and the axle set in the crotches of the two uprights, I opened my gateway and saw with pleasure that it revolved very rapidly, evenly, and with great strength. I also observed that the paddles were submerged just as they ought to be, only about a foot in the water, and that the rest of the wheel revolved in air. I also discovered that I could regulate the speed exactly by letting a larger or smaller quantity of water into the flume by means of my gate. I did not do all this without infinite detail and hard work, and it was at least a month before my wheel was completed and hung in its position. This brought me into July, and now I commenced to see ice form in the smooth pools near the river, and once, upon the fifteenth, was visited with a severe snow storm, but a day or two of pleasant weather soon carried it off. There were days also in this month when storms arose and lashed the ocean into monstrous billows, and at these times I visited the breakwater and East Signal Point and looked upon its grandeur. These were the days in which I felt blue and dispirited. But I also knew that the winter must ere this have reached its greatest severity, and although it was now really cold and everything frost-bound, yet it was not like zero weather at home. There were more mild and pleasant days than cold and unpleasant ones. There was evidently a warm current of the ocean embracing the island and keeping the climate mild. I felt confident that cold weather would soon be gone, and that I had nothing to fear on that account, for I found no difficulty in keeping myself perfectly warm at any time in the open air by a little exercise. As for my moccasins, they were warmer than any shoes I had ever worn, and my skin clothing was, even in this winter weather, uncomfortably warm, and on mild days I often used to change my sealskin coat that I had made myself for one of pliable goatskin leather without any hair upon it. My water-wheel I found was, although wonderfully light, of excellent strength, and when I constructed it I was well aware of the tough properties of the cane used in its formation, which might writhe and give, but would not break. I kept the axle down in the crotches or "journals" formed for it, by means of greased straps of rawhide, so that it could not jump upward, and yet would revolve easily without being bound or cramped. My next task was to connect my water-wheel with a series of pullies on the shore and near to the blast-furnace, so as to force a column of air into and through the ore that I intended to smelt, by means of the different channels that I had left for that purpose when building it, all of which ended or entered into one opening in the side nearest the water-wheel.
