Still alone – The Stranger's Request – The Farm established at the Corral – Twelve Years ago – The Boatswain's Mate of the Britannia– Left on Tabor Island – Cyrus Harding's Hand – The mysterious Document.
These last words justified the colonists' presentiment. There had been some mournful past, perhaps expiated in the sight of men, but from which his conscience had not yet absolved him. At any rate the guilty man felt remorse, he repented, and his new friends would have cordially pressed the hand which they sought; but he did not feel himself worthy to extend it to honest men! However, after the scene with the jaguar, he did not return to the forest, and from that day did not go beyond the enclosure of Granite House.
What was the mystery of his life? Would the stranger one day speak of it? Time alone could show. At any rate, it was agreed that his secret should never be asked from him, and that they would live with him as if they suspected nothing.
For some days their life continued as before. Cyrus Harding and Gideon Spilett worked together, sometimes chemists, sometimes experimentalists. The reporter never left the engineer except to hunt with Herbert, for it would not have been prudent to allow the lad to ramble alone in the forest; and it was very necessary to be on their guard. As to Neb and Pencroft, one day at the stables and poultry-yard, another at the corral, without reckoning work in Granite House, they were never in want of employment.
The stranger worked alone, and he had resumed his usual life, never appearing at meals, sleeping under the trees in the plateau, never mingling with his companions. It really seemed as if the society of those who had saved him was insupportable to him!
"But then," observed Pencroft, "why did he entreat the help of his fellow-creatures? Why did he throw that paper into the sea?"
"He will tell us why," invariably replied Cyrus Harding.
"Perhaps sooner than you think, Pencroft."
And, indeed, the day of confession was near.
On the 10th of December, a week after his return to Granite House, Harding saw the stranger approaching, who, in a calm voice and humble tone, said to him: "Sir, I have a request to make you."
"Speak," answered the engineer; "but first let me ask you a question."
At these words the stranger reddened, and was on the point of withdrawing. Cyrus Harding understood what was passing in the mind of the guilty man, who doubtless feared that the engineer would interrogate him on his past life.
Harding held him back.
"Comrade," said he, "we are not only your companions but your friends. I wish you to believe that, and now I will listen to you."
The stranger pressed his hand over his eyes. He was seized with a sort of trembling, and remained a few moments without being able to articulate a word.
"Sir," said he at last, "I have come to beg you to grant me a favour."
"What is it?"
"You have, four or five miles from here, a corral for your domesticated animals. These animals need to be taken care of. Will you allow me to live there with them?"
Cyrus Harding gazed at the unfortunate man for a few moments with a feeling of deep commiseration; then, —
"My friend," said he, "the corral has only stables hardly fit for animals."
"It will be good enough for me, sir."
"My friend," answered Harding, "we will not constrain you in anything. You wish to live at the corral, so be it. You will, however, be always welcome at Granite House. But since you wish to live at the corral we will make the necessary arrangements for your being comfortably established there."
"Never mind that, I shall do very well."
"My friend," answered Harding, who always intentionally made use of this cordial appellation, "you must let us judge what it will be best to do in this respect."
"Thank you, sir," replied the stranger as he withdrew.
The engineer then made known to his companions the proposal which had been made to him, and it was agreed that they should build a wooden house at the corral, which they would make as comfortable as possible.
That very day the colonists repaired to the corral with the necessary tools, and a week had not passed before the house was ready to receive its tenant. It was built about twenty feet from the sheds, and from there it was easy to overlook the flock of sheep, which then numbered more than eighty. Some furniture, a bed, table, bench, cupboard, and chest, were manufactured, and a gun, ammunition, and tools were carried to the corral.
The stranger, however, had seen nothing of his new dwelling, and he had allowed the settlers to work there without him, whilst he occupied himself on the plateau, wishing, doubtless, to put the finishing stroke to his work. Indeed, thanks to him, all the ground was dug up and ready to be sowed when the time came.
It was on the 20th of December that all the arrangements at the corral were completed. The engineer announced to the stranger that his dwelling was ready to receive him, and the latter replied that he would go and sleep there that very evening.
On this evening the colonists were gathered in the dining-room of Granite House. It was then eight o'clock, the hour at which their companion was to leave them. Not wishing to trouble him by their presence, and thus imposing on him the necessity of saying farewells which might perhaps be painful to him, they had left him alone, and ascended to Granite House.
Now, they had been talking in the room for a few minutes, when a light knock was heard at the door. Almost immediately the stranger entered, and without any preamble, —
"Gentlemen," said he, "before I leave you, it is right that you should know my history. I will tell it you."
These simple words profoundly impressed Cyrus Harding and his companions.
The engineer rose.
"We ask you nothing, my friend," said he, "it is your right to be silent."
"It is my duty to speak."
"Sit down, then."
"No, I will stand."
"We are ready to hear you," replied Harding.
The stranger remained standing in a corner of the room, a little in the shade. He was bareheaded, his arms folded across his chest, and it was in this posture that in a hoarse voice, speaking like some one who obliges himself to speak, he gave the following recital, which his auditors did not once interrupt —
"On the 20th of December, 1854, a steam-yacht, belonging to a Scotch nobleman, Lord Glenarvan, anchored off Cape Bermouilli, on the western coast of Australia, in the thirty-seventh parallel. On board this yacht were Lord Glenarvan and his wife, a major in the English army, a French geographer, a young girl, and a young boy. These two last were the children of Captain Grant, whose ship, the Britannia, had been lost, crew and cargo, a year before. The Duncan was commanded by Captain John Mangles, and manned by a crew of fifteen men.
"This is the reason the yacht at this time lay off the coast of Australia. Six months before, a bottle, enclosing a document written in English, German, and French, had been found in the Irish sea, and picked up by the Duncan. This document stated in substance that there still existed three survivors from the wreck of the Britannia, that these survivors were Captain Grant and two of his men, and that they had found refuge on some land, of which the document gave the latitude, but of which the longitude, effaced by the sea, was no longer legible.
"This latitude was 37° 11´ south, therefore, the longitude being unknown, if they followed the thirty-seventh parallel over continents and seas, they would be certain to reach the spot inhabited by Captain Grant and his two companions. The English Admiralty having hesitated to undertake this search, Lord Glenarvan resolved to attempt everything to find the captain. He communicated with Mary and Robert Grant, who joined him. The Duncan yacht was equipped for the distant voyage, in which the nobleman's family and the captain's children wished to take part; and the Duncan, leaving Glasgow, proceeded towards the Atlantic, passed through the Straits of Magellan, and ascended the Pacific as far as Patagonia, where, according to a previous interpretation of the document, they supposed that Captain Grant was a prisoner among the Indians.
"The Duncan disembarked her passengers on the western coast of Patagonia, and sailed to pick them up again on the eastern coast at Cape Corrientes. Lord Glenarvan traversed Patagonia, following the thirty-seventh parallel, and having found no trace of the captain, he re-embarked on the 13th of November, so as to pursue his search through the Ocean.
"After having unsuccessfully visited the islands of Tristan d'Acunha and Amsterdam, situated in her course, the Duncan, as I have said, arrived at Cape Bermouilli, on the Australian coast, on the 20th of December, 1854.
"It was Lord Glenarvan's intention to traverse Australia as he had traversed America, and he disembarked. A few miles from the coast was established a farm, belonging to an Irishman, who offered hospitality to the travellers. Lord Glenarvan made known to the Irishman the cause which had brought him to these parts, and asked if he knew whether a three-masted English vessel, the Britannia, had been lost less than two years before on the west coast of Australia.
"The Irishman had never heard of this wreck; but, to the great surprise of the bystanders, one of his servants came forward and said, —
"'My lord, praise and thank God! If Captain Grant is still living, he is living on the Australian shores.'
"'Who are you?' asked Lord Glenarvan.
"'A Scotchman like yourself, my lord,' replied the man; 'I am one of Captain Grant's crew – one of the castaways of the Britannia.'
"This man was called Ayrton. He was, in fact, the boatswain's mate of the Britannia, as his papers showed. But, separated from Captain Grant at the moment when the ship struck upon the rocks, he had till then believed that the captain with all his crew had perished, and that he, Ayrton, was the sole survivor of the Britannia.
"'Only,' added he, 'it was not on the west coast, but on the east coast of Australia that the vessel was lost; and if Captain Grant is still living, as his document indicates, he is a prisoner among the natives, and it is on the other coast that he must be looked for.'
"This man spoke in a frank voice and with a confident look; his words could not be doubted. The Irishman, in whose service he had been for more than a year, answered for his trustworthiness. Lord Glenarvan, therefore, believed in the fidelity of this man, and, by his advice, resolved to cross Australia, following the thirty-seventh parallel. Lord Glenarvan, his wife, the two children, the major, the Frenchman, Captain Mangles, and a few sailors composed the little band under the command of Ayrton, whilst the Duncan, under charge of the mate, Tom Austin, proceeded to Melbourne, there to await Lord Glenarvan's instructions.
"They set out on the 23rd of December, 1854.
"It is time to say that Ayrton was a traitor. He was, indeed, the boatswain's mate of the Britannia; but, after some dispute with his captain, he had endeavoured to incite the crew to mutiny and seize the ship, and Captain Grant had landed him, on the 8th of April, 1852, on the west coast of Australia, and then sailed, leaving him there, as was only just.
"Therefore this wretched man knew nothing of the wreck of the Britannia; he had just heard of it from Glenarvan's account. Since his abandonment, he had become, under the name of Ben Joyce, the leader of the escaped convicts; and if he boldly maintained that the wreck had taken place on the east coast, and led Lord Glenarvan to proceed in that direction, it was that he hoped to separate him from his ship, seize the Duncan, and make the yacht a pirate in the Pacific."
Here the stranger stopped for a moment. His voice trembled, but he continued, —
"The expedition set out and proceeded across Australia. It was inevitably unfortunate, since Ayrton, or Ben Joyce, as he may be called, guided it, sometimes preceded, sometimes followed by his band of convicts, who had been told what they had to do.
"Meanwhile the Duncan had been sent to Melbourne for repairs. It was necessary, then, to get Lord Glenarvan to order her to leave Melbourne and go to the east coast of Australia, where it would be easy to seize her. After having led the expedition near enough to the coast, in the midst of vast forests with no resources, Ayrton obtained a letter, which he was charged to carry to the mate of the Duncan– a letter which ordered the yacht to repair immediately to the east coast, to Twofold Bay, that is to say, a few days' journey from the place where the expedition had stopped. It was there that Ayrton had agreed to meet his accomplices, and two days after gaining possession of the letter, he arrived at Melbourne.
"So far the villain had succeeded in his wicked design. He would be able to take the Duncan into Twofold Bay, where it would be easy for the convicts to seize her, and her crew massacred, Ben Joyce would become master of the seas… But it pleased God to prevent the accomplishment of these terrible projects.
"Ayrton, arrived at Melbourne, delivered the letter to the mate, Tom Austin, who read it and immediately set sail; but judge of Ayrton's rage and disappointment, when the next day he found that the mate was taking the vessel, not to the east coast of Australia, to Twofold Bay, but to the east coast of New Zealand. He wished to stop him, but Austin showed him the letter!.. And indeed, by a providential error of the French geographer, who had written the letter, the east coast of New Zealand was mentioned as the place of destination.
"All Ayrton's plans were frustrated! He became outrageous. They put him in irons. He was then taken to the coast of New Zealand, not knowing what would become of his accomplices, or what would become of Lord Glenarvan.
"The Duncan cruised about on this coast until the 3rd of March. On that day Ayrton heard the report of guns. The guns of the Duncan were being fired, and soon Lord Glenarvan and his companions came on board.
"This is what had happened.
"After a thousand hardships, a thousand dangers, Lord Glenarvan had accomplished his journey, and arrived on the east coast of Australia, at Twofold Bay. 'No Duncan!' he telegraphed to Melbourne. They answered, 'Duncan sailed on the 18th instant. Destination unknown.'
"Lord Glenarvan could only arrive at one conclusion: that his honest yacht had fallen into the hands of Ben Joyce, and had become a pirate vessel!
"However, Lord Glenarvan would not give up. He was a bold and generous man. He embarked in a merchant vessel, sailed to the west coast of New Zealand, traversed it along the thirty-seventh parallel, without finding any trace of Captain Grant; but on the other side, to his great surprise, and by the will of Heaven, he found the Duncan, under command of the mate, who had been waiting for him for five weeks!
"This was on the 3rd of March 1855. Lord Glenarvan was now on board the Duncan, but Ayrton was there also. He appeared before the nobleman, who wished to extract from him all that the villain knew about Captain Grant. Ayrton refused to speak. Lord Glenarvan then told him, that at the first port they put into, he would be delivered up to the English authorities. Ayrton remained mute.
"The Duncan continued her voyage along the thirty-seventh parallel. In the meanwhile, Lady Glenarvan undertook to vanquish the resistance of the ruffian.
"At last, her influence prevailed, and Ayrton, in exchange for what he could tell, proposed that Lord Glenarvan should leave him on some island in the Pacific, instead of giving him up to the English authorities. Lord Glenarvan, resolving to do anything to obtain information about Captain Grant, consented.
"Ayrton then related all his life, and it was certain that he knew nothing from the day on which Captain Grant had landed him on the Australian coast.
"Nevertheless, Lord Glenarvan kept the promise which he had given. The Duncan continued her voyage and arrived at Tabor Island. It was there that Ayrton was to be landed, and it was there also that, by a veritable miracle, they found Captain Grant and two men, exactly on the thirty-seventh parallel.
"The convict, then, went to take their place on this desert islet, and at the moment he left the yacht these words were pronounced by Lord Glenarvan: —
"'Here, Ayrton, you will be far from any land, and without any possible communication with your fellow-creatures. You cannot escape from this islet on which the Duncan leaves you. You will be alone, under the eye of a God who reads the depths of the heart; but you will be neither lost nor forgotten, as was Captain Grant. Unworthy as you are to be remembered by men, men will remember you. I know where you are, Ayrton, and I know where to find you. I will never forget it!'
"And the Duncan, making sail, soon disappeared. This was on the 18th of March 1855.2
"Ayrton was alone, but he had no want of either ammunition, weapons, tools, or seeds.
"At his, the convict's disposal, was the house built by honest Captain Grant. He had only to live and expiate in solitude the crimes which he had committed.
"Gentlemen, he repented, he was ashamed of his crimes and was very miserable! He said to himself, that if men came some day to take him from that islet, he must be worthy to return amongst them! How he suffered, that wretched man! How he laboured to recover himself by work! How he prayed to be reformed by prayer! For two years, three years, this went on; but Ayrton, humbled by solitude, always looking for some ship to appear on the horizon, asking himself if the time of expiation would soon be complete, suffered as none other ever suffered! Oh! how dreadful was this solitude, to a heart tormented by remorse!
"But doubtless Heaven had not sufficiently punished this unhappy man, for he felt that he was gradually becoming a savage! He felt that brutishness was gradually gaining on him!
"He could not say if it was after two or three years of solitude; but at last he became the miserable creature you found!
"I have no need to tell you, gentlemen, that Ayrton, Ben Joyce, and I, are the same."
Cyrus Harding and his companions rose at the end of this account. It is impossible to say how much they were moved! What misery, grief, and despair lay revealed before them!
"Ayrton," said Harding, rising, "you have been a great criminal, but Heaven must certainly think that you have expiated your crimes! That has been proved by your having been brought again among your fellow-creatures. Ayrton, you are forgiven! And now you will be our companion?"
Ayrton drew back.
"Here is my hand!" said the engineer.
Ayrton grasped the hand which Harding extended to him, and great tears fell from his eyes.
"Will you live with us?" asked Cyrus Harding.
"Captain Harding, leave me some time longer," replied Ayrton, "leave me alone in the hut in the corral!"
"As you like, Ayrton," answered Cyrus Harding. Ayrton was going to withdraw, when the engineer addressed one more question to him: —
"One word more, my friend. Since it was your intention to live alone, why did you throw into the sea the document which put us on your track?"
"A document?" repeated Ayrton, who did not appear to know what he meant.
"Yes, the document which we found enclosed in a bottle, giving us the exact position of Tabor Island!"
Ayrton passed his hand over his brow, then after having thought, "I never threw any document into the sea!" he answered.
"Never," exclaimed Pencroft.
And Ayrton, bowing, reached the door and departed.
Conversation – Cyrus Harding and Gideon Spilett – An Idea of the Engineer's – The Electric Telegraph – The Wires – The Battery – The Alphabet – Fine Season – Prosperity of the Colony – Photography – An Appearance of Snow – Two Years in Lincoln Island.
"Poor man!" said Herbert, who had rushed to the door, but returned, having seen Ayrton slide down the rope of the lift and disappear in the darkness.
"He will come back," said Cyrus Harding.
"Come now, captain," exclaimed Pencroft, "what does that mean? What! wasn't it Ayrton who threw that bottle into the sea? Who was it then?"
Certainly, if ever a question was necessary to be made, it was that one!
"It was he," answered Neb, "only the unhappy man was half mad."
"Yes!" said Herbert, "and he was no longer conscious of what he was doing."
"It can only be explained in that way, my friends," replied Harding quickly, "and I understand now how Ayrton was able to point out exactly the situation of Tabor Island, since the events which had preceded his being left on the Island had made it known to him."
"However," observed Pencroft, "if he was not yet a brute when he wrote that document, and if he threw it into the sea seven or eight years ago, how is it that the paper has not been injured by damp?"
"That proves," answered Cyrus Harding, "that Ayrton was deprived of intelligence at a more recent time than he thinks."
"Of course it must be so," replied Pencroft, "without that the fact would be unaccountable."
"Unaccountable indeed," answered the engineer, who did not appear desirous to prolong the conversation.
"But has Ayrton told the truth?" asked the sailor.
"Yes," replied the reporter. "The story which he has told is true in every point. I remember quite well the account in the newspapers of the yacht expedition undertaken by Lord Glenarvan, and its result."
"Ayrton has told the truth," added Harding. "Do not doubt it, Pencroft, for it was painful to him. People tell the truth when they accuse themselves like that!"
The next day – the 21st of December – the colonists descended to the beach, and having climbed the plateau they found nothing of Ayrton. He had reached his house in the corral during the night, and the settlers judged it best not to agitate him by their presence. Time would doubtless perform what sympathy had been unable to accomplish.
Herbert, Pencroft, and Neb resumed their ordinary occupations. On this day the same work brought Harding and the reporter to the workshop at the Chimneys.
"Do you know, my dear Cyrus," said Gideon Spilett, "that the explanation you gave yesterday on the subject of the bottle has not satisfied me at all! How can it be supposed that the unfortunate man was able to write that document and throw the bottle into the sea without having the slightest recollection of it?"
"Nor was it he who threw it in, my dear Spilett."
"You think then…"
"I think nothing, I know nothing!" interrupted Cyrus Harding. "I am content to rank this incident among those which I have not been able to explain to this day!"
"Indeed, Cyrus," said Spilett, "these things are incredible! Your rescue, the case stranded on the sand, Top's adventure, and lastly this bottle… Shall we never have the answer to these enigmas?"
"Yes!" replied the engineer quickly, "yes, even if I have to penetrate into 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 mysteries in this world. There is a reason for everything unaccountable which has happened here, and that reason I shall discover. But in the meantime we must work and observe."
The month of January arrived. The year 1867 commenced. The summer occupations were assiduously continued. During the days which followed, Herbert and Spilett having gone in the direction of the corral, ascertained that Ayrton had taken possession of the habitation which had been prepared for him. He busied himself with the numerous flock confided to his care, and spared his companions the trouble of coming every two or three days to visit the corral. Nevertheless, in order not to leave Ayrton in solitude for too long a time, the settlers often paid him a visit.
It was not unimportant either, in consequence of some suspicions entertained by the engineer and Gideon Spilett, that this part of the island should be subject to a surveillance of some sort, and that Ayrton, if any incident occurred unexpectedly, should not neglect to inform the inhabitants of Granite House of it.
Nevertheless it might happen that something would occur which it would be necessary to bring rapidly to the engineer's knowledge. Independently of facts bearing on the mystery of Lincoln Island, many others might happen, which would call for the prompt interference of the colonists, – such as the sighting of a vessel, a wreck on the western coast, the possible arrival of pirates, etc.
Therefore Cyrus Harding resolved to put the corral in instantaneous communication with Granite House.
It was on the 10th of January that he made known his project to his companions.
"Why! how are you going to manage that, captain?" asked Pencroft. "Do you by chance happen to think of establishing a telegraph?"
"Exactly so," answered the engineer.
"Electric?" cried Herbert.
"Electric," replied Cyrus Harding. "We have all the necessary materials for making a battery, and the most difficult thing will be to stretch the wires, but by means of a draw-plate I think we shall manage it."
"Well, after that," returned the sailor, "I shall never despair of seeing ourselves some day rolling along on a railway!"
They then set to work, beginning with the most difficult thing, for, if they failed in that, it would be useless to manufacture the battery and other accessories.
The iron of Lincoln Island, as has been said, was of excellent quality, and consequently very fit for being drawn out. Harding commenced by manufacturing a draw-plate, that is to say, a plate of steel, pierced with conical holes of different sizes, which would successively bring the wire to the wished-for tenacity. This piece of steel, after having been tempered, was fixed in as firm a way as possible in a solid framework planted in the ground, only a few feet from the great fall, the motive power of which the engineer intended to utilise. In fact, as the fulling-mill was there, although not then in use, its beam moved with extreme power would serve to stretch out the wire by rolling it round itself. It was a delicate operation, and required much care. The iron, prepared previously in long thin rods, the ends of which were sharpened with the file, having been introduced into the largest hole of the draw-plate, was drawn out by the beam which wound it round itself, to a length of twenty-five or thirty feet, then unrolled, and the same operation was performed successively through the holes of a less size. Finally, the engineer obtained wires from forty to fifty feet long, which could be easily fastened together and stretched over the distance of five miles, which separated the corral from the bounds of Granite House.
It did not take more than a few days to perform this work, and indeed as soon as the machine had been commenced, Cyrus Harding left his companions to follow the trade of wire-drawers, and occupied himself with manufacturing his battery.
It was necessary to obtain a battery with a constant current. It is known that the elements of modern batteries are generally composed of retort coal, zinc, and copper. Copper was absolutely wanting to the engineer, who, notwithstanding all his researches, had never been able to find any trace of it in Lincoln Island, and was therefore obliged to do without it. Retort coal, that is to say, the hard graphyte which is found in the retorts of gas manufactories, after the coal has been dehydrogenised, could have been obtained, but it would have been necessary to establish a special apparatus, involving great labour. As to zinc, it may be remembered that the case found at Flotsam Point was lined with this metal, which could not be better utilised than for this purpose.
Cyrus Harding, after mature consideration, decided to manufacture a very simple battery, resembling as nearly as possible that invented by Becquerel in 1820, and in which zinc only is employed. The other substances, azotic acid and potash, were all at his disposal.
The way in which the battery was composed was as follows, and the results were to be attained by the reaction of acid and potash on each other. A number of glass bottles were made and filled with azotic acid. The engineer corked them by means of a stopper through which passed a glass tube, bored at its lower extremity, and intended to be plunged into the acid by means of a clay stopper secured by a rag. Into this tube, through its upper extremity, he poured a solution of potash, previously obtained by burning and reducing to ashes various plants, and in this way the acid and potash could act on each other through the clay.
Cyrus Harding then took two slips of zinc, one of which was plunged into azotic acid, the other into a solution of potash. A current was immediately produced, which was transmitted from the slip of zinc in the bottle to that in the tube, and the two slips having been connected by a metallic wire the slip in the tube became the positive pole, and that in the bottle the negative pole of the apparatus. Each bottle, therefore, produced as many currents as united would be sufficient to produce all the phenomena of the electric telegraph. Such was the ingenious and very simple apparatus constructed by Cyrus Harding, an apparatus which would allow them to establish a telegraphic communication between Granite House and the corral.
On the 6th of February was commenced the planting, along the road to the corral, of posts, furnished with glass insulators, and intended to support the wire. A few days after, the wire was extended, ready to produce the electric current at a rate of twenty thousand miles a second.
Two batteries had been manufactured, one for Granite House, the other for the corral; for if it was necessary the corral should be able to communicate with Granite House, it might also be useful that Granite House should be able to communicate with the corral.
As to the receiver and manipulator, they were very simple. At the two stations the wire was wound round a magnet, that is to say, round a piece of soft iron surrounded with a wire. The communication was thus established between the two poles, the current, starting from the positive pole, traversed the wire, passed through the magnet which was temporarily magnetised, and returned through the earth to the negative pole. If the current was interrupted the magnet immediately became unmagnetised. It was sufficient to place a plate of soft iron before the magnet, which, attracted during the passage of the current, would fall back when the current was interrupted. This movement of the plate thus obtained, Harding could easily fasten to it a needle arranged on a dial, bearing the letters of the alphabet, and in this way communicate from one station to the other.
