The Battery and the Boiler by Robert Michael Ballantyne (best books for 7th graders .txt) 📕

/> It would take a huge volume to give a detailed account of all the qualities, powers, and peculiarities of this wild Spark. We will just touch on a few facts which are necessary to the elucidation of our tale.

A great event in the world's history happened in the year 1745. It was nothing less than the capture and imprisonment of wild, daring, dashing Electricity. To the Dutch philosophers belongs the honour of catching him. They caught him--they even bottled him, like ordinary spirits, and called his prison a _Leyden Jar_.

From that date our Spark became the useful and obedient slave of man. Yet is he ever ready, when the smallest conceivable door, hole, or chink is left open, to dash out of the prison-house man has made for him, and escape into his native earth.

He has no hope now, however, of escaping altogether, for he cannot resist the allurement of rubbing, by which, as well as by chemical action and other means, we can summon him, like the genii of Aladdin's lamp, at any moment, from the "vasty deep," and compel him to do our work.

And what sort of work, it may be asked, can this volatile fellow perform? We cannot tell all--the list is too long. Let us consider a few of them. If we fabricate tea-pots, sugar-basins, spoons, or anything else of base metal, he can and will, at our bidding, cover the same with silver or yellow gold. If we grow dissatisfied with our candles and gas, he will, on being summoned, and properly directed by the master minds to whom he owns allegiance, kindle our lamps and fill our streets and mansions with a blaze of noonday splendour. If we grow weary of steam, and give him orders, he will drive our tram-cars and locomotives with railway speed, _minus_ railway smoke and fuss. He is a very giant in the chemist's laboratory, and, above all, a swift messenger to carry the world's news. Even when out and raging to and fro in a wild state, more than half-disposed to rend our mansions, and split our steeples, and wreck our ships, we have only to provide him with a tiny metal stair-case, down which he will instantly glide from the upper regions to the earth without noise or damage. Shakespeare never imagined, and Mercury never accomplished, the speed at which he travels; and he will not only carry our news, or express our sentiments and wishes far and wide over the land, but he will rush with them, over rock, sand, mud, and ooze, along the bottom of the deep deep sea!

And this brings us to a point. Some of the master minds before mentioned, having conceived the idea that telegraphic communication might be carried on under water, set about experimenting. Between the years 1839 and 1851 enterprising men in the Old World and the New suggested, pondered, planned, and placed wires under water, along which our Spark ran more or less successfully.

One of the difficulties of these experiments consisted in this, that, while the Spark runs readily along one class of substances, he cannot, or will not, run along others. Substances of the first class, comprising the metals, are called conductors; those of the second class, embracing, among other things, all resinous substances, are styled non-conductors. Now, water is a good conductor. So that although the Spark will stick to his wires when insulated on telegraph-posts on land, he will bolt from them at once and take to flight the moment he gets under water. This difficulty was overcome by coating the wires with gutta-percha, which, being a non-conductor, imprisoned the Spark, and kept him, as it were, on the line.

A copper wire covered in this manner was successfully laid between England and France in 1850. When tested, this cable did not work well. Minute imperfections, in the form of air-holes in the gutta-percha, afforded our Spark an opportunity to bolt; and he did bolt, as a matter of course--for electricity has no sense of honour, and cannot be trusted near the smallest loop-hole. The imperfections were remedied; the door was effectually locked, after which the first submarine cable of importance was actually laid down, and worked well. French and English believers turned up hands and eyes in delighted amazement, as they held converse across the sea, while unbelievers were silenced and confounded.

This happy state of things, however, lasted for only a few hours. Suddenly the intercourse ceased. The telegraphists at both ends energised with their handles and needles, but without any result. The cable was dumb. Our Spark had evidently escaped!

There is no effect without a cause. The cause of that interruption was soon discovered.

Early that morning a French fisherman had sauntered down to the port of Boulogne and embarked in his boat. A British seaman, having nothing to do but smoke and meditate, was seated on a coil of rope at the time, enjoying himself and the smells with which that port is not unfamiliar. He chanced to be a friend of that French fisherman.

"You're early afloat, Mounseer," he said.

"Oui, monsieur. Vill you com'? I go for feesh."

"Well, _wee_; I go for fun."

They went accordingly and bore away to the northward along the coast before a light breeze,--past the ruined towers which France had built to guard her port in days gone by; past the steep cliffs beyond Boulogne; past the lovely beach of Wimereux, with its cottages nestled among the sand-hills, and its silted-up harbour, whence Napoleon the First had intended to issue forth and descend on perfidious Albion--but didn't; past cliffs, and bays, and villages further on, until they brought up off Cape Grisnez. Here the Frenchman let down his trawl, and fished up, among other curiosities of the deep, the submarine cable!

"Behold! fat is dis?" he exclaimed, with glaring eyes, uplifted brows, shoulders shrugged, hands spread out, and fingers expanded.

"The sea-sarpint grow'd thin," suggested the Englishman.

"Non; c'est seaveed--veed de most 'strordinair in de vorld. Oui, donnez-moi de hache, de hax, mon ami."

His friend handed him the axe, wherewith lie cut off a small portion of the cable and let the end go. Little did that fisherman know that he had also let our Spark go free, and cruelly dashed, for a time at least, the budding hopes of two nations--but so it was. He bore his prize in triumph to Boulogne, where he exhibited it as a specimen of rare seaweed with its centre filled with gold, while the telegraph clerks at both ends sat gazing in dismay at their useless instruments.

Thus was the first submarine electric cable destroyed. And with the details of its destruction little Robin was intimately acquainted, for cousin Sam had been a member of the staff that had worked that telegraph--at least he had been a boy in the office,--and in after years he so filled his cousin's mind with the importance of that cable, and the grandeur and difficulty of the enterprise, that Robin became powerfully sympathetic--so much so that when Sam, in telling the story, came to the point where the Frenchman accomplished its destruction, Robin used to grieve over it as though he had lost a brother, or a kitten, or his latest toy!

We need scarcely add that submarine cable telegraphy had not received its death-blow on that occasion. Its possibility had been demonstrated. The very next year (1851) Mr T.R. Crampton, with Messrs. Wollaston, Kuper, and others, made and laid an improved cable between Dover and Calais, and ere long many other parts of the world were connected by means of snaky submarine electric cables.


CHAPTER THREE.


EARLY ASPIRATIONS.

One pleasant summer afternoon, Mr Wright, coming in from the office, seated himself beside his composed little wife, who was patching a pair of miniature pantaloons.

"Nan," said the husband, with a perplexed look, "what _are_ we to do with our Robin when he grows up?"

"George," answered the composed wife, "don't you think it is rather soon to trouble ourselves with that question? Robin is a mere child yet. We must first give him a good education."

"Of course, I know that," returned the perplexed husband, "still, I can't help thinking about what is to be done after he has had the good education. You know I have no relation in the world except brother Richard, who is as poor as myself. We have no influential friends to help him into the Army or the Navy or the Indian Civil Service; and the Church, you know, is not suitable for an imp. Just look at him _now_!"

Mrs Wright looked through the window, over one of those sunny landscapes which are usually described as "smiling," across a winding rivulet, and at last fixed her gorgeous eyes on a tall post, up which a small black object was seen to be struggling.

"What can he be up to?" said the father.

"He seems to be up the telegraph-post," said the mother, "investigating the wires, no doubt. I heard him talking about telegraphy to Madge this morning--retailing what cousin Sam tries to teach him,--and I shouldn't wonder if he were now endeavouring to make sure that what he told her was correct, for you know he is a thorough investigator."

"Yes, I know it," murmured the father, with a grim pursing of his lips; "he investigated the inside of my watch last week, to find out, as he said, what made the noise in its `stummick,' and it has had intermittent fever ever since. Two days ago he investigated my razor,--it is now equal to a cross-cut saw; and as to my drawers and papers, excepting those which I lock up, there is but one word which fully describes the result of his investigations, and that is--chaos."

There was, in truth, some ground for that father's emotions, for Master Robin displayed investigative, not to say destructive, capacities far in advance of his years.

"Never mind, George," said Mrs Wright soothingly, "we must put up with his little ways as best we may, consoling ourselves with the reflection that Robin has genius and perseverance, with which qualities he is sure to make his way in the world."

"He has at all events made his way up the telegraph-post," said Mr Wright, his smile expanding and the grimness of it departing; "see! the rascal is actually stretching out his hand to grasp one of the wires. Ha! hallo!"

The composed wife became suddenly discomposed, and gave vent to a scream, for at that moment the small black object which they had been watching with so much interest was seen to fall backward, make a wild grasp at nothing with both hands, and fall promptly to the ground.

His father threw up the window, leaped out, dashed across the four-feet-wide lawn, cleared the winding rivulet, and cut, like a hunted hare, over the smiling landscape towards the telegraph-post, at the foot of which he picked up his unconscious though not much injured son.

"What made you climb the post, Robin?" asked his cousin Madge that evening as she nursed the adventurous boy on her knee--and Madge was a very motherly nurse, although a full year younger than Robin.

"I kimed it to see if I could hear the 'trissity," replied the injured one.

"The lek-trissity," said Madge, correcting. "You must learn to p'onounce your words popperly, dear. You'll never be a great man
