Part 29 (1/2)

Our s.h.i.+ps are very large, that each pa.s.senger may have the utmost accommodation, for we do not like to imprison our people in a narrow s.p.a.ce; and an ordinary vessel holds several hundred pa.s.sengers, besides merchandise.

To propel our vessels we use electric power, and they move as fast as your quickest railway trains; but nevertheless can be stopped almost instantaneously. The wheels outside the body of the swan, set in motion by internal electric machinery, revolve with extraordinary rapidity. To set the machinery in motion it is necessary to wind up powerful chains, and a strong horse is used for the purpose. One horse is sufficient for the longest voyage, but four are kept on board in case of accidents. The machinery could be so constructed that the horse would not be necessary; but for this arrangement much more s.p.a.ce would be required. If even all the horses were disabled--a thing which hitherto has never occurred--the machinery could be kept in motion by manual power and leverage.

Though the propelling power is great, it can be reversed, moderated, or entirely suspended with the greatest ease. As soon as the s.h.i.+p is stopped, the two large ”web-feet” attached to the keel fall down and a.s.sist in checking her headway.

To steer our vessels we use a winch or rudder, which runs from stem to stern underneath the swan's belly, and is connected with a wheel below the water. This rudder, which is made of metal and covered with hippopotamus hide, is sharp and slightly rounded. The mode in which it is fixed gives the steersman great control over the vessel, the more so as it moves the swan's head as well as the tail by direct action.

TIMBER FOR s.h.i.+PS.

Before timber is employed for s.h.i.+ps, or indeed for constructions of any kind, it is thoroughly seasoned by being exposed to the sun at particular hours of the day. Timbers that have pa.s.sed through this process never shrink or warp.

In accordance with my directions, wood cannot be used in s.h.i.+pbuilding until so prepared that no insects will touch it.

In certain parts of the bottom of the great ravine is a liquid, the admixture of refuse of all kinds. After some years this liquid becomes of a golden colour for the depth of about two inches only; beneath, it is of a muddy brown. It was accidentally discovered that the golden liquor so hardened wood that no insect could make any impression upon it, and no moisture could penetrate the fibres. There is some difficulty in skimming and obtaining the liquid in a pure state; but the operation having been performed, it is carefully preserved in large vats and remains ready for use.

The timber having been thoroughly seasoned in the sun, each plank is cut and shaped to the exact form required, and is then soaked in this liquid. If the process of cutting were delayed till after the timber had been soaked, the parts where the cuttings had been made would be unprotected from the insects. If the soaking were delayed until after the s.h.i.+p had been put together, the four sides of each of the timbers where it is joined to other timbers, would in like manner be unprotected, and the insects would eat their way between. The care exercised was the more necessary, as it was essential that the wood under the hippopotamus hide should be preserved from internal as well as external influences. If the wood had shrunk after it had been once covered, parts of the hide would become slack, and serious inconveniences would have ensued. I never knew one of our Swan vessels to spring a leak or to wear out. The vessels built under my rule will exist unimpaired for many centuries, whilst those built under the former system were broken to pieces on account of their foulness and leakage, chiefly caused by the ravages of insects.

THE COMPa.s.s.

The compa.s.s used in our s.h.i.+ps is different to yours, being based on the fact that each country has a different attraction to certain liquids. In short, we apply an electrical power entirely unknown to you.

THE ANCHOR.

The anchor is made of iron-marble, which is the strongest composition we have, and which, you will recollect, was used in the construction of the Mountain Supporter.

In shape the anchor resembles a body with six legs, like a fly--three on either side. Each leg has a crook at the end, which will grapple firmly wherever the least hold can be obtained.

The anchor is let out and hauled in by machinery made on a principle resembling the machinery of the s.h.i.+p itself, but, of course, on a very much smaller scale.

The rope holding the anchor is made of Bisson hair, a very strong material; and although there is little probability of its breaking, there are four other ropes of the same material secured to the body of the anchor, to serve in case of accidents. There is no strain whatever in the meantime on these reserved ropes, which hang slack, and would only come taut and into play in case of the princ.i.p.al rope being broken.

PICTURES FROM WATER.

”The records of your actions are borne in the waters, in the air, in electricity, in the unknown powers that, by the command of Him who made them all, pervade infinite s.p.a.ce. His might is everywhere; and the man who transgresses, sins in the presence of myriads of witnesses.”

In my reign some interesting discoveries were made with regard to water.

From a source situated in the midst of a lovely scene flowed a spring of remarkably pure quality, some drops of which, taken at a distance, presented, when viewed through a microscope, a true picture of the landscape close to the source from whence they came. Rocks, trees, shrubs, sky, were there faithfully delineated with their varied forms and colours, together with the resemblances of two persons, lovers, seated on the banks. As we afterwards learned, they had been attracted by the beauty of the scene, had sat for a long time in the same place, and their portrait was, as it were, fixed on the water.

The electricity of the sun and light had thrown the shadow or picture of the scene on the fluid, whose electricity had been sufficiently strong to retain it, and bear it to the spot whence the drops of water had been taken. This circ.u.mstance, and our knowledge that the reflecting power of the water is the result in part of its peculiar electricity, led to a very interesting discovery.
