“Well, Mr. Starr, here it never rains. But I needn’t describe to you all the advantages, which you know as well as myself. Here we are at the cottage. That is the chief thing, and I again say you are welcome, sir.” Simon Ford, followed by Harry, ushered their guest into the dwelling. James Starr found himself in a large room lighted by numerous lamps, one hanging from the colored beams of the roof. “The soup is ready, wife,” said Ford, “and it mustn’t be kept waiting any more than Mr. Starr. He is as hungry as a miner, and he shall see that our boy doesn’t let us want for anything in the cottage! By-the-bye, Harry,” added the old overman, turning to his son, “Jack Ryan came here to see you.” “I know, father. We met him in the Yarrow shaft.” “He’s an honest and a merry fellow,” said Ford; “but he seems to be quite happy above ground. He hasn’t the true miner’s blood in his veins. Sit down, Mr. Starr, and have a good dinner, for we may not sup till late.” As the engineer and his hosts were taking their places: “One moment, Simon,” said James Starr. “Do you want me to eat with a good appetite?” “It will be doing us all possible honor, Mr. Starr,” answered Ford. “Well, in order to eat heartily, I must not be at all anxious. Now I have two questions to put to you.” “Go on, sir.” “Your letter told me of a communication which was to be of an interesting nature.” “It is very interesting indeed.” “To you?” “To you and to me, Mr. Starr. But I do not want to tell it you until after dinner, and on the very spot itself. Without that you would not believe me.” “Simon,” resumed the engineer, “look me straight in the face. An interesting communication? Yes. Good! I will not ask more,” he added, as if he had read the reply in the old overman’s eyes. “And the second question?” asked the latter. “Do you know, Simon, who the person is who can have written this?” answered the engineer, handing him the anonymous letter. Ford took the letter and read it attentively. Then giving it to his son, “Do you know the writing?” he asked. “No, father,” replied Harry. “And had this letter the Aberfoyle postmark?” inquired Simon Ford. “Yes, like yours,” replied James Starr. “What do you think of that, Harry?” said his father, his brow darkening. “I think, father,” returned Harry, “that someone has had some interest in trying to prevent Mr. Starr from coming to the place where you invited him.” “But who,” exclaimed the old miner, “who could have possibly guessed enough of my secret?” And Simon fell into a reverie, from which he was aroused by his wife. “Let us begin, Mr. Starr,” she said. “The soup is already getting cold. Don’t think any more of that letter just now.” On the old woman’s invitation, each drew in his chair, James Starr opposite to Madge--to do him honor--the father and son opposite to each other. It was a good Scotch dinner. First they ate “hotchpotch,” soup with the meat swimming in capital broth. As old Simon said, his wife knew no rival in the art of preparing hotchpotch. It was the same with the “cockyleeky,” a cock stewed with leeks, which merited high praise. The whole was washed down with excellent ale, obtained from the best brewery in Edinburgh. But the principal dish consisted of a “haggis,” the national pudding, made of meat and barley meal. This remarkable dish, which inspired the poet Burns with one of his best odes, shared the fate of all the good things in this world--it passed away like a dream. Madge received the sincere compliments of her guest. The dinner ended with cheese and oatcake, accompanied by a few small glasses of “usquebaugh,” capital whisky, five and twenty years old--just Harry’s age. The repast lasted a good hour. James Starr and Simon Ford had not only eaten much, but talked much too, chiefly of their past life in the old Aberfoyle mine. Harry had been rather silent. Twice he had left the table, and even the house. He evidently felt uneasy since the incident of the stone, and wished to examine the environs of the cottage. The anonymous letter had not contributed to reassure him. Whilst he was absent, the engineer observed to Ford and his wife, “That’s a fine lad you have there, my friends.” “Yes, Mr. Starr, he is a good and affectionate son,” replied the old overman earnestly. “Is he happy with you in the cottage?” “He would not wish to leave us.” “Don’t you think of finding him a wife, some day?” “A wife for Harry,” exclaimed Ford. “And who would it be? A girl from up yonder, who would love merry-makings and dancing, who would prefer her clan to our mine! Harry wouldn’t do it!” “Simon,” said Madge, “you would not forbid that Harry should take a wife.” “I would forbid nothing,” returned the old miner, “but there’s no hurry about that. Who knows but we may find one for him--” Harry re-entered at that moment, and Simon Ford was silent. When Madge rose from the table, all followed her example, and seated themselves at the door of the cottage. “Well, Simon,” said the engineer, “I am ready to hear you.” “Mr. Starr,” responded Ford, “I do not need your ears, but your legs. Are you quite rested?” “Quite rested and quite refreshed, Simon. I am ready to go with you wherever you like.” “Harry,” said Simon Ford, turning to his son, “light our safety lamps.” “Are you going to take safety lamps!” exclaimed James Starr, in amazement, knowing that there was no fear of explosions of fire-damp in a pit quite empty of coal. “Yes, Mr. Starr, it will be prudent.” “My good Simon, won’t you propose next to put me in a miner’s dress?” “Not just yet, sir, not just yet!” returned the old overman, his deep-set eyes gleaming strangely. Harry soon reappeared, carrying three safety lamps. He handed one of these to the engineer, the other to his father, and kept the third hanging from his left hand, whilst his right was armed with a long stick. “Forward!” said Simon Ford, taking up a strong pick, which was leaning against the wall of the cottage. “Forward!” echoed the engineer. “Good-by, Madge.” “GOD speed you!” responded the good woman. “A good supper, wife, do you hear?” exclaimed Ford. “We shall be hungry when we come back, and will do it justice!” CHAPTER V. SOME STRANGE PHENOMENA MANY superstitious beliefs exist both in the Highlands and Lowlands of Scotland. Of course the mining population must furnish its contingent of legends and fables to this mythological repertory. If the fields are peopled with imaginary beings, either good or bad, with much more reason must the dark mines be haunted to their lowest depths. Who shakes the seam during tempestuous nights? who puts the miners on the track of an as yet unworked vein? who lights the fire-damp, and presides over the terrible explosions? who but some spirit of the mine? This, at least, was the opinion commonly spread among the superstitious Scotch. In the first rank of the believers in the supernatural in the Dochart pit figured Jack Ryan, Harry’s friend. He was the great partisan of all these superstitions. All these wild stories were turned by him into songs, which earned him great applause in the winter evenings. But Jack Ryan was not alone in his belief. His comrades affirmed, no less strongly, that the Aberfoyle pits were haunted, and that certain strange beings were seen there frequently, just as in the Highlands. To hear them talk, it would have been more extraordinary if nothing of the kind appeared. Could there indeed be a better place than a dark and deep coal mine for the freaks of fairies, elves, goblins, and other actors in the fantastical dramas? The scenery was all ready, why should not the supernatural personages come there to play their parts? So reasoned Jack Ryan and his comrades in the Aberfoyle mines. We have said that the different pits communicated with each other by means of long subterranean galleries. Thus there existed beneath the county of Stirling a vast tract, full of burrows, tunnels, bored with caves, and perforated with shafts, a subterranean labyrinth, which might be compared to an enormous ant-hill. Miners, though belonging to different pits, often met, when going to or returning from their work. Consequently there was a constant opportunity of exchanging talk, and circulating the stories which had their origin in the mine, from one pit to another. These accounts were transmitted with marvelous rapidity, passing from mouth to mouth, and gaining in wonder as they went. Two men, however, better educated and with more practical minds than the rest, had always resisted this temptation. They in no degree believed in the intervention of spirits, elves, or goblins. These two were Simon Ford and his son. And they proved it by continuing to inhabit the dismal crypt, after the desertion of the Dochart pit. Perhaps good Madge, like every Highland woman, had some leaning towards the supernatural. But she had to repeat all these stories to herself, and so she did, most conscientiously, so as not to let the old traditions be lost. Even had Simon and Harry Ford been as credulous as their companions, they would not have abandoned the mine to the imps and fairies. For ten years, without missing a single day, obstinate and immovable in their convictions, the father and son took their picks, their sticks, and their lamps. They went about searching, sounding the rock with a sharp blow, listening if it would return a favor-able sound. So long as the soundings had not been pushed to the granite of the primary formation, the Fords were agreed that the search, unsuccessful to-day, might succeed to-morrow, and that it ought to be resumed. They spent their whole life in endeavoring to bring Aberfoyle back to its former prosperity. If the father died before the hour of success, the son was to go on with the task alone. It was during these excursions that Harry was more particularly struck by certain phenomena, which he vainly sought to explain. Several times, while walking along some narrow cross-alley, he seemed to hear sounds similar to those which would be produced by violent blows of a pickax against the wall. Harry hastened to seek the cause of this mysterious work. The tunnel was empty. The light from the young miner’s lamp, thrown on the wall, revealed no trace of any recent work with pick or crowbar. Harry would then ask himself if it was not the effect of some acoustic illusion, or some strange and fantastic echo. At other times, on suddenly throwing a bright light into a suspicious-looking cleft in the rock, he thought he saw a shadow. He rushed forward. Nothing, and there was no opening to permit a human being to evade his pursuit! Twice in one month, Harry, whilst visiting the west end of the pit, distinctly heard distant reports, as if some miner had exploded a charge of dynamite. The second time, after many careful researches, he found that a pillar had just been blown up. By the light of his lamp, Harry carefully examined the place attacked by the explosion. It had not been made in a simple embankment of stones, but in a mass of schist, which had penetrated to this depth in the coal stratum. Had the object of the explosion been to discover a new vein? Or had someone wished simply to destroy this portion of the mine? Thus he questioned, and when he made known this occurrence to his father, neither could the old overman nor he himself answer the question in a satisfactory way. “It is very queer,” Harry often repeated. “The presence of an unknown being in the mine seems impossible, and yet there can be no doubt about it. Does someone besides ourselves wish to find out if a seam yet exists? Or, rather, has he attempted to destroy what remains of the Aberfoyle mines? But for what reason? I will find that out, if it should cost me my life!” A fortnight before the day on which Harry Ford guided the engineer through the labyrinth of the Dochart pit, he had been on the point of attaining the object of his search. He was going over the southwest end of the mine, with a large lantern in his hand. All at once, it seemed to him that a light was suddenly extinguished, some hundred feet before him, at the end of a narrow passage cut obliquely through the rock. He darted forward. His search was in vain. As Harry would not admit a supernatural explanation for a physical occurrence, he concluded that certainly some strange being prowled about in the pit. But whatever he could do, searching with the greatest care, scrutinizing every crevice in the gallery, he found nothing for his trouble. If Jack Ryan and the other superstitious fellows in the mine had seen these lights, they would, without fail, have called them supernatural, but Harry did not dream of doing so, nor did his father. And when they talked over these phenomena, evidently due to a physical cause, “My lad,” the old man would say, “we must wait. It will all be explained some day.” However, it must be observed that, hitherto, neither Harry nor his father had ever been exposed to any act of violence. If the stone which had fallen at the feet of James Starr had been thrown by the hand of some ill-disposed person, it was the first criminal act of that description. James Starr was of opinion that the stone had become detached from the roof of the gallery; but Harry would not admit of such a simple explanation. According to him, the stone had not fallen, it had been thrown; for otherwise, without rebounding, it could never have described a trajectory as it did. Harry saw in it a direct attempt against himself and his father, or even against the engineer. CHAPTER VI. SIMON FORD’S EXPERIMENT THE old clock in the cottage struck one as James Starr and his two companions went out. A dim light penetrated through the ventilating shaft into the glade. Harry’s lamp was not necessary here, but it would very soon be of use, for the old overman was about to conduct the engineer to the very end of the Dochart pit. After following the principal gallery for a distance of two miles, the three explorers--for, as will be seen, this was a regular exploration--arrived at the entrance of a narrow tunnel. It was like a nave, the roof of which rested on woodwork, covered with white moss. It followed very nearly the line traced by the course of the river Forth, fifteen hundred feet above. “So we are going to the end of the last vein?” said James Starr. “Ay! You know the mine well still.” “Well, Simon,” returned the engineer, “it will be difficult to go further than that, if I don’t mistake.” “Yes, indeed, Mr. Starr. That was where our picks tore out the last bit of coal in the seam. I remember it as if it were yesterday. I myself gave that last blow, and it re-echoed in my heart more dismally than on the rock. Only sandstone and schist were round us after that, and when the truck rolled towards the shaft, I followed, with my heart as full as though it were a funeral. It seemed to me that the soul of the mine was going with it.” The gravity with which the old man uttered these words impressed the engineer, who was not far from sharing his sentiments. They were those of the sailor who leaves his disabled vessel--of the proprietor who sees the house of his ancestors pulled down. He pressed Ford’s hand; but now the latter seized that of the engineer, and, wringing it: “That day we were all of us mistaken,” he exclaimed. “No! The old mine was not dead. It was not a corpse that the miners abandoned; and I dare to assert, Mr. Starr, that its heart beats still.” “Speak, Ford! Have you discovered a new vein?” cried the engineer, unable to contain himself. “I know you have! Your letter could mean nothing else.” “Mr. Starr,” said Simon Ford, “I did not wish to tell any man but yourself.” “And you did quite right, Ford. But tell me how, by what signs, are you sure?” “Listen, sir!” resumed Simon. “It is not a seam that I have found.” “What is it, then?” “Only positive proof that such a seam exists.” “And the proof?” “Could fire-damp issue from the bowels of the earth if coal was not there to produce it?” “No, certainly not!” replied the engineer. “No coal, no fire-damp. No effects without a cause.” “Just as no smoke without fire.” “And have you recognized the presence of light carburetted hydrogen?” “An old miner could not be deceived,” answered Ford. “I have met with our old enemy, the fire-damp!” “But suppose it was another gas,” said Starr. “Firedamp is almost without smell, and colorless. It only really betrays its presence by an explosion.” “Mr. Starr,” said Simon Ford, “will you let me tell you what I have done? Harry had once or twice observed something remarkable in his excursions to the west end of the mine. Fire, which suddenly went out, sometimes appeared along the face of the rock or on the embankment of the further galleries. How those flames were lighted, I could not and cannot say. But they were evidently owing to the presence of fire-damp, and to me fire-damp means a vein of coal.” “Did not these fires cause any explosion?” asked the engineer quickly. “Yes, little partial explosions,” replied Ford, “such as I used to cause myself when I wished to ascertain the presence of fire-damp. Do you remember how formerly it was the custom to try to prevent explosions before our good genius, Humphry Davy, invented his safety-lamp?” “Yes,” replied James Starr. “You mean what the ‘monk,’ as the men called him, used to do. But I have never seen him in the exercise of his duty.” “Indeed, Mr. Starr, you are too young, in spite of your five-and-fifty years, to have seen that. But I, ten years older, often saw the last ‘monk’ working in the mine. He was called so because he wore a long robe like a monk. His proper name was the ‘fireman.’ At that time there was no other means of destroying the bad gas but by dispersing it in little explosions, before its buoyancy had collected it in too great quantities in the heights of the galleries. The monk, as we called him, with his face masked, his head muffled up, all his body tightly wrapped in a thick felt cloak, crawled along the ground. He could breathe down there, when the air was pure; and with his right hand he waved above his head a blazing torch. When the firedamp had accumulated in the air, so as to form a detonating mixture, the explosion occurred without being fatal, and, by often renewing this operation, catastrophes were prevented. Sometimes the ‘monk’ was injured or killed in his work, then another took his place. This was done in all mines until the Davy lamp was universally adopted. But I knew the plan, and by its means I discovered the presence of firedamp and consequently that of a new seam of coal in the Dochart pit.” All that the old overman had related of the so-called “monk” or “fireman” was perfectly true. The air in the galleries of mines was formerly always purified in the way described. Fire-damp, marsh-gas, or carburetted hydrogen, is colorless, almost scentless; it burns with a blue flame, and makes respiration impossible. The miner could not live in a place filled with this injurious gas, any more than one could live in a gasometer full of common gas. Moreover, fire-damp, as well as the latter, a mixture of inflammable gases, forms a detonating mixture as soon as the air unites with it in a proportion of eight, and perhaps even five to the hundred. When this mixture is lighted by any cause, there is an explosion, almost always followed by a frightful catastrophe. As they walked on, Simon Ford told the engineer all that he had done to attain his object; how he was sure that the escape of fire-damp took place at the very end of the farthest gallery in its western part, because he had provoked small and partial explosions, or rather little flames, enough to show the nature of the gas, which escaped in a small jet, but with a continuous flow. An hour after leaving the cottage, James Starr and his two companions had gone a distance of four miles. The engineer, urged by anxiety and hope, walked on without noticing the length of the way. He pondered over all that the old miner had told him, and mentally weighed all the arguments which the latter had given in support of his belief. He agreed with him in thinking that the continued emission of carburetted hydrogen certainly showed the existence of a new coal-seam. If it had been merely a sort of pocket, full of gas, as it is sometimes found amongst the rock, it would soon have been empty, and the phenomenon have ceased. But far from that. According to Simon Ford, the fire-damp escaped incessantly, and from that fact the existence of an important vein might be considered certain. Consequently, the riches of the Dochart pit were not entirely exhausted. The chief question now was, whether this was merely a vein which would yield comparatively little, or a bed occupying a large extent. Harry, who preceded his father and the engineer, stopped. “Here we are!” exclaimed the old miner. “At last, thank Heaven! you are here, Mr. Starr, and we shall soon know.” The old overman’s voice trembled slightly. “Be calm, my man!” said the engineer. “I am as excited as you are, but we must not lose time.” The gallery at this end of the pit widened into a sort of dark cave. No shaft had been pierced in this part, and the gallery, bored into the bowels of the earth, had no direct communication with the surface of the earth. James Starr, with intense interest, examined the place in which they were standing. On the walls of the cavern the marks of the pick could still be seen, and even holes in which the rock had been blasted, near the termination of the working. The schist was excessively hard, and it had not been necessary to bank up the end of the tunnel where the works had come to an end. There the vein had failed, between the schist and the tertiary sandstone. From this very place had been extracted the last piece of coal from the Dochart pit. “We must attack the dyke,” said Ford, raising his pick; “for at the other side of the break, at more or less depth, we shall assuredly find the vein, the existence of which I assert.” “And was it on the surface of these rocks that you found out the fire-damp?” asked James Starr. “Just there, sir,” returned Ford, “and I was able to light it only by bringing my lamp near to the cracks in the rock. Harry has done it as well as I.” “At what height?” asked Starr. “Ten feet from the ground,” replied Harry. James Starr had seated himself on a rock. After critically inhaling the air of the cavern, he gazed at the two miners, almost as if doubting their words, decided as they were. In fact, carburetted hydrogen is not completely scentless, and the engineer, whose sense of smell was very keen, was astonished that it had not revealed the presence of the explosive gas. At any rate, if the gas had mingled at all with the surrounding air, it could only be in a very small stream. There was no danger of an explosion, and they might without fear open the safety lamp to try the experiment, just as the old miner had done before. What troubled James Starr was, not lest too much gas mingled with the air, but lest there should be little or none. “Could they have been mistaken?” he murmured. “No: these men know what they are about. And yet--” He waited, not without some anxiety, until Simon Ford’s phenomenon should have taken place. But just then it seemed that Harry, like himself, had remarked the absence of the characteristic odor of fire-damp; for he exclaimed in an altered voice, “Father, I should say the gas was no longer escaping through the cracks!” “No longer!” cried the old miner--and, pressing his lips tight together, he snuffed the air several times. Then, all at once, with a sudden movement, “Hand me your lamp, Harry,” he said. Ford took the lamp with a trembling hand. He drew off the wire gauze case which surrounded the wick, and the flame burned in the open air. As they had expected, there was no explosion, but, what was more serious, there was not even the slight crackling which indicates the presence of a small quantity of firedamp. Simon took the stick which Harry was holding, fixed his lamp to the end of it, and raised it high above his head, up to where the gas, by reason of its buoyancy, would naturally accumulate. The flame of the lamp, burning straight and clear, revealed no trace of the carburetted hydrogen. “Close to the wall,” said the engineer. “Yes,” responded Ford, carrying the lamp to that part of the wall at which he and his son had, the evening before, proved the escape of gas. The old miner’s arm trembled whilst he tried to hoist the lamp up. “Take my place, Harry,” said he. Harry took the stick, and successively presented the lamp to the different fissures in the rock; but he shook his head, for of that slight crackling peculiar to escaping fire-damp he heard nothing. There was no flame. Evidently not a particle of gas was escaping through the rock. “Nothing!” cried Ford, clenching his fist with a gesture rather of anger than disappointment. A cry escaped Harry. “What’s the matter?” asked Starr quickly. “Someone has stopped up the cracks in the schist!” “Is that true?” exclaimed the old miner. “Look, father!” Harry was not mistaken. The obstruction of the fissures was clearly visible by the light of the lamp. It had been recently done with lime, leaving on the rock a long whitish mark, badly concealed with coal dust. “It’s he!” exclaimed Harry. “It can only be he!” “He?” repeated James Starr in amazement. “Yes!” returned the young man, “that mysterious being who haunts our domain, for whom I have watched a hundred times without being able to get at him--the author, we may now be certain, of that letter which was intended to hinder you from coming to see my father, Mr. Starr, and who finally threw that stone at us in the gallery of the Yarrow shaft! Ah! there’s no doubt about it; there is a man’s hand in all that!” Harry spoke with such energy that conviction came instantly and fully to the engineer’s mind. As to the old overman, he was already convinced. Besides, there they were in the presence of an undeniable fact--the stopping-up of cracks through which gas had escaped freely the night before. “Take your pick, Harry,” cried Ford; “mount on my shoulders, my lad! I am still strong enough to bear you!” The young man understood in an instant. His father propped himself up against the rock. Harry got upon his shoulders, so that with his pick he could reach the line of the fissure. Then with quick sharp blows he attacked it. Almost directly afterwards a slight sound was heard, like champagne escaping from a bottle--a sound commonly expressed by the word “puff.” Harry again seized his lamp, and held it to the opening. There was a slight report; and a little red flame, rather blue at its outline, flickered over the rock like a Will-o’-the-Wisp. Harry leaped to the ground, and the old overman, unable to contain his joy, grasped the engineer’s hands, exclaiming, “Hurrah! hurrah! hurrah! Mr. Starr. The fire-damp burns! the vein is there!” CHAPTER VII. NEW ABERFOYLE THE old overman’s experiment had succeeded. Firedamp, it is well known, is only generated in coal seams; therefore the existence of a vein of precious combustible could no longer be doubted. As to its size and quality, that must be determined later. “Yes,” thought James Starr, “behind that wall lies a carboniferous bed, undiscovered by our soundings. It is vexatious that all the apparatus of the mine, deserted for ten years, must be set up anew. Never mind. We have found the vein which was thought to be exhausted, and this time it shall be worked to the end!” “Well, Mr. Starr,” asked Ford, “what do you think of our discovery? Was I wrong to trouble you? Are you sorry to have paid this visit to the Dochart pit?” “No, no, my old friend!” answered Starr. “We have not lost our time; but we shall be losing it now, if we do not return immediately to the cottage. To-morrow we will come back here. We will blast this wall with dynamite. We will lay open the new vein, and after a series of soundings, if the seam appears to be large, I will form a new Aberfoyle Company, to the great satisfaction of the old shareholders. Before three months have passed, the first corves full of coal will have been taken from the new vein.” “Well said, sir!” cried Simon Ford. “The old mine will grow young again, like a widow who remarries! The bustle of the old days will soon begin with the blows of the pick, and mattock, blasts of powder, rumbling of wagons, neighing of horses, creaking of machines! I shall see it all again! I hope, Mr. Starr, that you will not think me too old to resume my duties of overman?” “No, Simon, no indeed! You wear better than I do, my old friend!” “And, sir, you shall be our viewer again. May the new working last for many years, and pray Heaven I shall have the consolation of dying without seeing the end of it!” The old miner was overflowing with joy. James Starr fully entered into it; but he let Ford rave for them both. Harry alone remained thoughtful. To his memory recurred the succession of singular, inexplicable circumstances attending the discovery of the new bed. It made him uneasy about the future. An hour afterwards, James Starr and his two companions were back in the cottage. The engineer supped with good appetite, listening with satisfaction to all the plans unfolded by the old overman; and had it not been for his excitement about the next day’s work, he would never have slept better than in the perfect stillness of the cottage. The following day, after a substantial breakfast, James Starr, Simon Ford, Harry, and even Madge herself, took the road already traversed the day before. All looked like regular miners. They carried different tools, and some dynamite with which to blast the rock. Harry, besides a large lantern, took a safety lamp, which would burn for twelve hours. It was more than was necessary for the journey there and back, including the time for the working--supposing a working was possible. “To work! to work!” shouted Ford, when the party reached the further end of the passage; and he grasped a heavy crowbar and brandished it. “Stop one instant,” said Starr. “Let us see if any change has taken place, and if the fire-damp still escapes through the crevices.” “You are right, Mr. Starr,” said Harry. “Whoever stopped it up yesterday may have done it again to-day!” Madge, seated on a rock, carefully observed the excavation, and the wall which was to be blasted. It was found that everything was just as they left it. The crevices had undergone no alteration; the carburetted hydrogen still filtered through, though in a small stream, which was no doubt because it had had a free passage since the day before. As the quantity was so small, it could not have formed an explosive mixture with the air inside. James Starr and his companions could therefore proceed in security. Besides, the air grew purer by rising to the heights of the Dochart pit; and the fire-damp, spreading through the atmosphere, would not be strong enough to make any explosion. “To work, then!” repeated Ford; and soon the rock flew in splinters under his skillful blows. The break was chiefly composed of pudding-stone, interspersed with sandstone and schist, such as is most often met with between the coal veins. James Starr picked up some of the pieces, and examined them carefully, hoping to discover some trace of coal. Starr having chosen the place where the holes were to be drilled, they were rapidly bored by Harry. Some cartridges of dynamite were put into them. As soon as the long, tarred safety match was laid, it was lighted on a level with the ground. James Starr and his companions then went off to some distance. “Oh! Mr. Starr,” said Simon Ford, a prey to agitation, which he did not attempt to conceal, “never, no, never has my old heart beaten so quick before! I am longing to get at the vein!” “Patience, Simon!” responded the engineer. “You don’t mean to say that you think you are going to find a passage all ready open behind that dyke?” “Excuse me, sir,” answered the old overman; “but of course I think so! If there was good luck in the way Harry and I discovered this place, why shouldn’t the good luck go on?” As he spoke, came the explosion. A sound as of thunder rolled through the labyrinth of subterranean galleries. Starr, Madge, Harry, and Simon Ford hastened towards the spot. “Mr. Starr! Mr. Starr!” shouted the overman. “Look! the door is broken open!” Ford’s comparison was justified by the appearance of an excavation, the depth of which could not be calculated. Harry was about to spring through the opening; but the engineer, though excessively surprised to find this cavity, held him back. “Allow time for the air in there to get pure,” said he. “Yes! beware of the foul air!” said Simon. A quarter of an hour was passed in anxious waiting. The lantern was then fastened to the end of a stick, and introduced into the cave, where it continued to burn with unaltered brilliancy. “Now then, Harry, go,” said Starr, “and we will follow you.” The opening made by the dynamite was sufficiently large to allow a man to pass through. Harry, lamp in hand, entered unhesitatingly, and disappeared in the darkness. His father, mother, and James Starr waited in silence. A minute--which seemed to them much longer--passed. Harry did not reappear, did not call. Gazing into the opening, James Starr could not even see the light of his lamp, which ought to have illuminated the dark cavern. Had the ground suddenly given way under Harry’s feet? Had the young miner fallen into some crevice? Could his voice no longer reach his companions? The old overman, dead to their remonstrances, was about to enter the opening, when a light appeared, dim at first, but gradually growing brighter, and Harry’s voice was heard shouting, “Come, Mr. Starr! come, father! The road to New Aberfoyle is open!” If, by some superhuman power, engineers could have raised in a block, a thousand feet thick, all that portion of the terrestrial crust which supports the lakes, rivers, gulfs, and territories of the counties of Stirling, Dumbarton, and Renfrew, they would have found, under that enormous lid, an immense excavation, to which but one other in the world can be compared--the celebrated Mammoth caves of Kentucky. This excavation was composed of several hundred divisions of all sizes and shapes. It might be called a hive with numberless ranges of cells, capriciously arranged, but a hive on a vast scale, and which, instead of bees, might have lodged all the ichthyosauri, megatheriums, and pterodactyles of the geological epoch. A labyrinth of galleries, some higher than the most lofty cathedrals, others like cloisters, narrow and winding--these following a horizontal line, those on an incline or running obliquely in all directions--connected the caverns and allowed free communication between them. The pillars sustaining the vaulted roofs, whose curves allowed of every style, the massive walls between the passages, the naves themselves in this layer of secondary formation, were composed of sandstone and schistous rocks. But tightly packed between these useless strata ran valuable veins of coal, as if the black blood of this strange mine had circulated through their tangled network. These fields extended forty miles north and south, and stretched even under the Caledonian Canal. The importance of this bed could not be calculated until after soundings, but it would certainly surpass those of Cardiff and Newcastle. We may add that the working of this mine would be singularly facilitated by the fantastic dispositions of the secondary earths; for by an unaccountable retreat of the mineral matter at the geological epoch, when the mass was solidifying, nature had already multiplied the galleries and tunnels of New Aberfoyle. Yes, nature alone! It might at first have been supposed that some works abandoned for centuries had been discovered afresh. Nothing of the sort. No one would have deserted such riches. Human termites had never gnawed away this part of the Scottish subsoil; nature herself had done it all. But, we repeat, it could be compared to nothing but the celebrated Mammoth caves, which, in an extent of more than twenty miles, contain two hundred and twenty-six avenues, eleven lakes, seven rivers, eight cataracts, thirty-two unfathomable wells, and fifty-seven domes, some of which are more than four hundred and fifty feet in height. Like these caves, New Aberfoyle was not the work of men, but the work of the Creator. Such was this new domain, of matchless wealth, the discovery of which belonged entirely to the old overman. Ten years’ sojourn in the deserted mine, an uncommon pertinacity in research, perfect faith, sustained by a marvelous mining instinct--all these qualities together led him to succeed where so many others had failed. Why had the soundings made under the direction of James Starr during the last years of the working stopped just at that limit, on the very frontier of the new mine? That was all chance, which takes great part in researches of this kind. However that might be, there was, under the Scottish subsoil, what might be called a subterranean county, which, to be habitable, needed only the rays of the sun, or, for want of that, the light of a special planet. Water had collected in various hollows, forming vast ponds, or rather lakes larger than Loch Katrine, lying just above them. Of course the waters of these lakes had no movement of currents or tides; no old castle was reflected there; no birch or oak trees waved on their banks. And yet these deep lakes, whose mirror-like surface was never ruffled by a breeze, would not be without charm by the light of some electric star, and, connected by a string of canals, would well complete the geography of this strange domain. Although unfit for any vegetable production, the place could be inhabited by a whole population. And who knows but that in this steady temperature, in the depths of the mines of Aberfoyle, as well as in those of Newcastle, Alloa, or Cardiff--when their contents shall have been exhausted--who knows but that the poorer classes of Great Britain will some day find a refuge? CHAPTER VIII. EXPLORING AT Harry’s call, James Starr, Madge, and Simon Ford entered through the narrow orifice which put the Dochart pit in communication with the new mine. They found themselves at the beginning of a tolerably wide gallery. One might well believe that it had been pierced by the hand of man, that the pick and mattock had emptied it in the working of a new vein. The explorers question whether, by a strange chance, they had not been transported into some ancient mine, of the existence of which even the oldest miners in the county had ever known. No! It was merely that the geological layers had left this passage when the secondary earths were in course of formation. Perhaps some torrent had formerly dashed through it; but now it was as dry as if it had been cut some thousand feet lower, through granite rocks. At the same time, the air circulated freely, which showed that certain natural vents placed it in communication with the exterior atmosphere. This observation, made by the engineer, was correct, and it was evident that the ventilation of the new mine would be easily managed. As to the fire-damp which had lately filtered through the schist, it seemed to have been contained in a pocket now empty, and it was certain that the atmosphere of the gallery was quite free from it. However, Harry prudently carried only the safety lamp, which would insure light for twelve hours. James Starr and his companions now felt perfectly happy. All their wishes were satisfied. There was nothing but coal around them. A sort of emotion kept them silent; even Simon Ford restrained himself. His joy overflowed, not in long phrases, but in short ejaculations. It was perhaps imprudent to venture so far into the crypt. Pooh! they never thought of how they were to get back. The gallery was practicable, not very winding. They met with no noxious exhalations, nor did any chasm bar the path. There was no reason for stopping for a whole hour; James Starr, Madge, Harry, and Simon Ford walked on, though there was nothing to show them what was the exact direction of this unknown tunnel. And they would no doubt have gone farther still, if they had not suddenly come to the end of the wide road which they had followed since their entrance into the mine. The gallery ended in an enormous cavern, neither the height nor depth of which could be calculated. At what altitude arched the roof of this excavation--at what distance was its opposite wall--the darkness totally concealed; but by the light of the lamp the explorers could discover that its dome covered a vast extent of still water--pond or lake--whose picturesque rocky banks were lost in obscurity. “Halt!” exclaimed Ford, stopping suddenly. “Another step, and perhaps we shall fall into some fathomless pit.” “Let us rest awhile, then, my friends,” returned the engineer. “Besides, we ought to be thinking of returning to the cottage.” “Our lamp will give light for another ten hours, sir,” said Harry. “Well, let us make a halt,” replied Starr; “I confess my legs have need of a rest. And you, Madge, don’t you feel tired after so long a walk?” “Not over much, Mr. Starr,” replied the sturdy Scotchwoman; “we have been accustomed to explore the old Aberfoyle mine for whole days together.” “Tired? nonsense!” interrupted Simon Ford; “Madge could go ten times as far, if necessary. But once more, Mr. Starr, wasn’t my communication worth your trouble in coming to hear it? Just dare to say no, Mr. Starr, dare to say no!” “Well, my old friend, I haven’t felt so happy for a long while!” replied the engineer; “the small part of this marvelous mine that we have explored seems to show that its extent is very considerable, at least in length.” “In width and in depth, too, Mr. Starr!” returned Simon Ford. “That we shall know later.” “And I can answer for it! Trust to the instinct of an old miner! It has never deceived me!” “I wish to believe you, Simon,” replied the engineer, smiling. “As far as I can judge from this short exploration, we possess the elements of a working which will last for centuries!” “Centuries!” exclaimed Simon Ford; “I believe you, sir! A thousand years and more will pass before the last bit of coal is taken out of our new mine!” “Heaven grant it!” returned Starr. “As to the quality of the coal which crops out of these walls?” “Superb! Mr. Starr, superb!” answered Ford; “just look at it yourself!” And so saying, with his pick he struck off a fragment of the black rock. “Look! look!” he repeated, holding it close to his lamp; “the surface of this piece of coal is shining! We have here fat coal, rich in bituminous matter; and see how it comes in pieces, almost without dust! Ah, Mr. Starr! twenty years ago this seam would have entered into a strong competition with Swansea and Cardiff! Well, stokers will quarrel for it still, and if it costs little to extract it from the mine, it will not sell at a less price outside.” “Indeed,” said Madge, who had taken the fragment of coal and was examining it with the air of a connoisseur; “that’s good quality of coal. Carry it home, Simon, carry it back to the cottage! I want this first piece of coal to burn under our kettle.” “Well said, wife!” answered the old overman, “and you shall see that I am not mistaken.” “Mr. Starr,” asked Harry, “have you any idea of the probable direction of this long passage which we have been following since our entrance into the new mine?” “No, my lad,” replied the engineer; “with a compass I could perhaps find out its general bearing; but without a compass I am here like a sailor in open sea, in the midst of fogs, when there is no sun by which to calculate his position.” “No doubt, Mr. Starr,” replied Ford; “but pray don’t compare our position with that of the sailor, who has everywhere and always an abyss under his feet! We are on firm ground here, and need never be afraid of foundering.” “I won’t tease you, then, old Simon,” answered James Starr. “Far be it from me even in jest to depreciate the New Aberfoyle mine by an unjust comparison! I only meant to say one thing, and that is that we don’t know where we are.” “We are in the subsoil of the county of Stirling, Mr. Starr,” replied Simon Ford; “and that I assert as if--” “Listen!” said Harry, interrupting the old man. All listened, as the young miner was doing. His ears, which were very sharp, had caught a dull sound, like a distant murmur. His companions were not long in hearing it themselves. It was above their heads, a sort of rolling sound, in which though it was so feeble, the successive CRESCENDO and DIMINUENDO could be distinctly heard. All four stood for some minutes, their ears on the stretch, without uttering a word. All at once Simon Ford exclaimed, “Well, I declare! Are trucks already running on the rails of New Aberfoyle?” “Father,” replied Harry, “it sounds to me just like the noise made by waves rolling on the sea shore.” “We can’t be under the sea though!” cried the old overman. “No,” said the engineer, “but it is not impossible that we should be under Loch Katrine.” “The roof cannot have much thickness just here, if the noise of the water is perceptible.” “Very little indeed,” answered James Starr, “and that is the reason this cavern is so huge.” “You must be right, Mr. Starr,” said Harry. “Besides, the weather is so bad outside,” resumed Starr, “that the waters of the loch must be as rough as those of the Firth of Forth.” “Well! what does it matter after all?” returned Simon Ford; “the seam won’t be any the worse because it is under a loch. It would not be the first time that coal has been looked for under the very bed of the ocean! When we have to work under the bottom of the Caledonian Canal, where will be the harm?” “Well said, Simon,” cried the engineer, who could not restrain a smile 1 2 « , . , . 3 , . 4 . , , . » 5 6 , , . 7 , 8 . 9 10 « , , » , « 11 . . , 12 ! 13 - - , , » , , « 14 . » 15 16 « , . . » 17 18 « , » ; « 19 . . 20 , . , , 21 . » 22 23 : 24 25 « , , » . « 26 ?
