The Mysterious Island by Jules Verne (uplifting books for women txt) 📕

“Do you know, Cyrus, that your explanation of yesterday about the bottle does not satisfy me at all? It is impossible to suppose that this unhappy creature could have written that paper, and thrown the bottle into the sea, without remembering anything about it!”

“Consequently, it is not he who threw it there, my dear Spilett!”

“Then you believe⁠—”

“I believe nothing, I know nothing!” replied Smith, interrupting the reporter. “I place this incident with those others which I have not been able to explain!”

“In truth, Cyrus,” said Spilett, “these things are incredible. Your rescue, the box thrown up on the beach, Top’s adventures, and now this bottle. Will we never have an answer to these enigmas?”

“Yes,” answered the engineer, earnestly, “yes, when I shall have penetrated the bowels of this island!”

“Chance will, perhaps, give us the key to this mystery.”

“Chance, Spilett! I do not believe in chance any more than I believe in mystery in this world. There is a cause for everything, however inexplicable, which has happened here, and I will discover it. But, while waiting, let us watch and work.”

January arrived, and the year 1867 began. The works had been pushed forward vigorously. One day Herbert and Spilett, passing the corral, ascertained that Ayrton had taken possession of his abode. He occupied himself with the large herd confided to his care, and thus saved his companions the necessity of visiting it two or three times a week. Nevertheless, in order not to leave Ayrton too much alone, they frequently went there.

It was just as well⁠—owing to certain suspicions shared by Smith and Spilett⁠—that this part of the island should be under a certain supervision, and Ayrton, if anything happened, would not fail to let the inhabitants of Granite House know of it.

Possibly, some sudden event might happen, which it would be important to communicate to the engineer without delay. And, aside from whatever might be connected with the mystery of the island, other things, requiring the prompt intervention of the colonists, might occur, as, for example, the discovering of a ship in the offing and in sight of the west coast, a wreck on that shore, the possible arrival of pirates, etc.

So Smith determined to place the corral in instant communication with Granite House.

It was the 10th of January when he told his project to his companions.

“How are you going to do such a thing as that, Mr. Smith?” asked Pencroff. “Maybe you propose to erect a telegraph!”

“That is precisely what I propose to do.”

“Electric?” exclaimed Herbert.

“Electric,” responded Smith. “We have everything necessary for making a battery, and the most difficult part will be to make the wires, but I think we can succeed.”

“Well, after this,” replied the sailor, “I expect someday to see us riding along on a railway!”

They entered upon the work at once, beginning with the most difficult part, that is to say, the manufacture of the wires, since, if that failed, it would be useless to make the battery and other accessories.

The iron of Lincoln Island was, as we know, of excellent quality, and, therefore, well adapted to the purpose. Smith began by making a steel plate, pierced with conical holes of different sizes, which would bring the wire to the desired size. This piece of steel, after having been tempered “through and through,” was fixed firmly to a solid framework sunk in the ground, only a few feet distant from the waterfall⁠—the motive power which the engineer intended to use.

And, indeed, there was the fulling-mill, not then in use, the main shaft of which turned with great force, and would serve to draw out the wire and roll it around itself.

The operation was delicate and required great care. The iron, previously made into long and thin bars, with tapering ends, having been introduced into the largest hole of the drawing-plate, was drawn out by the main shaft of the mill, rolled out to a length of twety-five or thirty feet, then unrolled, and pulled, in turn, through the smaller holes; and at length, the engineer obtained wires thirty or forty feet long, which it was easy to join together and place along the five miles between the corral and Granite House.

It took but a little while to get this work under way, and then, Smith, making his companions the wire-drawers, busied himself in the construction of his battery.

It was necessary to make a battery with a constant circuit. We know that modern batteries are usually made of a certain kind of coke, zinc, and copper. Copper the engineer was without, since, in spite of all his efforts, he had been unable to find a trace of it on the island. The coke, which is that hard deposit obtained from gas retorts could be procured, but it would be necessary to arrange a special apparatus⁠—a difficult thing to do. As to the zinc, it will be remembered that the box found on Jetsam Point, was lined with a sheet of that metal, which could not be better utilized than at present.

Smith, after deep reflection, resolved to make a very simple battery, something like that which Becquerel invented in 1820, in which zinc alone is used. The other substances, nitric-acid and potash, he had at hand.

The manner in which he made this battery, in which the current was produced by the action of the acid and the potash on each other, was as follows:⁠—

A certain number of glass vessels were made and filled with nitric-acid. They were corked with perforated corks, containing glass tubes reaching into the acid, and stopped with clay plugs, connected with threads. Into these tubes the engineer poured a solution of potash⁠—obtained from burnt plants⁠—and thus the acid and the potash reacted on each other through the clay.

Then Smith plunged two plates of zinc, the one in the nitric acid, the other in the solution, and thus produced a circuit between the tube and jar, and as these plates had been connected by a bit of wire, the one
