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.
