Perseverance Island; Or, The Robinson Crusoe of the Nineteenth Century

by Douglas Frazar

When I desired to submerge it I had only to saw away each of these slats, on either side, and it would drop into the ocean, leaving the outer framework—or bedstead, if you please—floating; for my boat was to be built, of course, less than eighteen feet long and ten wide, so as to rest wholly upon these slats and not upon the framework of the cradle that supported the slats. This took me a long time to finish; but what was time to me whilst revolving the problem of my escape, which was not yet solved. Till I knew how I was to escape I should never again be in a hurry.

To build my boat I commenced by making two watertight tanks, each sixteen feet long and two feet square, and two smaller ones, each six feet long and of the same dimensions otherwise as the long ones; these, placed upon the slats of my cradle, gave me a parallelogram composed of four water-tight tanks, all made out of my rolled iron and riveted together firmly. I had to erect a derrick to hoist them into place, but once in the cradle I had only to bind the two ends of each extremity of the long tanks to the short ones placed at right angles to them and I had the foundations of my boat laid. I bound the small tanks in place, as also the large ones, by bands of iron, several in number, which I brought together on one side by means of what is called a turn buckle, such as is often seen on iron bridges, both ends of the bands being formed with a screw-thread, and fitting into this turn-buckle nut on both sides, which could be then tightened by means of a lever, so as to bring an immense binding force upon each band.

Upon the outer edge of this parallelogram of tanks I had left a sort of comb of iron, some three inches in height, already pierced, or rather punched, ready to receive the roof of the boat, also air-tight, to be bolted to it, so that when all was done my platform of tanks would be nearly two feet wide within the boat, and allow me plenty of margin to rest any kind of a movable platform upon, or deck over the space that was left open, some fourteen feet long by six feet wide.

The nearest description that I can give of this roof is, that it rose in all directions at an angle of about forty-five degrees till it was bolted to a large flat surface made up of several sheets of rolled iron, which formed the top, which was ten feet long and four feet wide. This flat roof was fitted with a manhole, somewhat large in proportion to the rest of the boat, at least two feet square, and fitted over a raised rib of iron, which was packed with greased milkweed floss, and closed on the inside by set-screws, that were worked with a short iron lever, so as to make the opening perfectly air-tight.

I commenced this chapter by saying that I did not intend to make such a fool of myself as the old Robinson Crusoe did, and that I was not going to make any errors either of judgment or figures; and yet I had not my boat completed as far as I have described before I discovered that I had been a silly ass, fully as silly as it was possible for a mechanic to be, and one day it flashed upon me that my whole cradle, with its air-tight chests, was an egregious folly; that I had not the least need in the world for it, and that I had wasted time, labor, and patience in perfecting it. Carried away, as I was, with the means I intended to employ to sink and raise my boat I had totally overlooked the fact that as now being built, and as it would be launched, that it would float itself, the size of the four air-tight tanks being sufficient to float five times the upper structure built on top of them.

As I am writing a veritable history, and no fable, it behooves me to tell the truth, and it was with feelings of both mortification and mirth that I surveyed my partially finished work. It was the mental contemplation of a series of air-cocks, weights, pumps, etc., to be hereinafter described, that had led me astray as to the buoyancy of the boat as it now stood, and it was what I was going to use the tanks for, rather than what they now were, that had led me to this error. But then there was no great harm done. I had not to change the plan of the boat in the minutest particular, and the cradle might after all be advantageous in launching it, and preserve it from any casualty. Therefore, with the exception of my loss of time, I was nothing the worse; still I was rather crestfallen to think what a mistake I had made. But after mourning for a short time I set to work with renewed ardor to complete my task.

After having strapped the four tanks together and covered them with the iron roof, as described, I went on to complete the remainder of the boat, in this manner. In the interior, which I could easily reach by getting up from underneath the ways through two of the slats of the cradle, I arranged the following: The space in which I had to work was about fourteen feet in length, six feet wide, and eight feet high from the bottom of the tanks to the flat roof, which contained the manhole, which, for the present I left open, to give me both light and air. In the first place I connected all these four tanks together by means of a half-circular arm of piping some three inches in diameter, which I placed in each of the four corners of the parallelogram formed by the interior of the boat, leading from one tank to the other, where the latter met at an angle, so that the air that each contained was put in direct communication with the others. These connecting pipes were fitted in with a flange and riveted, and were placed a few inches from the bottom of the tanks, thus making really one tank of the whole. As the roof was fastened to the outside of these tanks, I had a seat or margin running round all the sides of the interior two feet wide, from the outer or further side of which arose the roofing. I could, therefore, easily lay any kind of a movable deck over this open space of fourteen feet by six feet, resting the ends of all my planks upon the top of the tanks in any direction.

Having connected all the tanks so as virtually to form one, so far as concerned being one air-chamber, I then went to work and pierced the perpendicular side of one of the tanks quite near the bottom and inserted a similar pipe to the horizontal ones that connected the tanks at the angles. This pipe, however, was in the form of a right angle, or rather its two ends were at a right angle, the bend being of a circular form. It pierced the tank near the bottom, as I have said, extended in a horizontal line some eight inches, and then gradually turned in a circular manner till the other end, about one foot in length, pointed downward, in an exact right-angle from the end entering the tank. This was put on with a flange, and made water-tight, and in the top of it, about three inches from the tank, was fixed a stopcock, with a long rod, which arose inside the boat, parallel with the side of the tank, till it ended in a handle, situated some ten inches higher than the top of the tanks. Near this, also, I erected another piece of pipe, which entered the top of the tank and pierced the roof of the boat, which was also fitted with a stopcock. Still another pipe pierced the roof, which was fitted with a stopcock outside as well as inside, and depended down into the boat some four feet from the roof. These four pipes, with their stopcocks, were so arranged as to be all near to each other, so that I could control them all without moving in my position, and were made at about the middle of what I called the starboard side of my boat, though it would be hard to say which side starboard was, as both ends of the boat were exactly alike up to the present time. But as I was eventually to have a propeller and rudder, which would define the stern, I had already concluded that the part of the boat nearest the water should be the bows, and hence I knew which to call the starboard side and which the port side. Added to the pipes and stopcocks already enumerated was one which was simply about a foot in height, which pierced the tank on the top, some few inches from the inner edge, and near the others. It was also fitted with a stopcock, and, that my readers may fully understand the uses to which I put all these appliances at a later day, it will be well, perhaps, to name them, so that when used it will be possible to understand to which of the numerous ones I refer; and to prevent confusion, and to make myself understood, I will say that the pipes at the angles of the tanks I took no note of, they not being fitted with any cocks, and only made to connect all the tanks together, so that any action I might make with any of the stopcocks would be communicated to the whole system of tanks, of which the foundations and main part of the boat was formed.

The pipes with stopcocks I named as follows: The one leading down into what would be the water when the boat was launched, and below the bottom of the tank some inches, fitted with a long rod and handle, I called the water-pipe and stopcock; the one that connected the tank with the roof, the tank air-pipe and stopcock; the one that pierced the roof and depended into the interior, the atmospheric pipe and outer and inner stopcocks; the one that stood erect, ten inches in height, the pump-pipe and stopcock. So that I had four pipes and five stopcocks to my boat, all of which had their uses, as shall be related.
