IsTo. 4. THE BLACK-INDIES. 123 "never, no, never has my old heart been so deeply stirred. I long to attack the vein !" " Patience, Simon," replied the. engineer. " You have no idea of finding an open gallery behind this wall?" " Excuse me, Mr. James," replied the old overseer ; "I have every idea possible ! If there has been good luck in the way Harry and I have discovered this deposit, why should not this luck continue to the end ?" The explosion of the dynamite took place ; a low rumbling spread through the net-work of subterranean galleries. James Starr, Madge, Harry and Simon Ford returned immediately toward the wall of the cavern. " Mr. James, Mr. James !" cried the old overseer, " see ! the door is broken down !" This comparison of Simon Ford was justi- fied by the appearance of an excavation of in- calculable depth. Harry was going to spring in through the opening. The engineer, while greatly surprised at finding this cavity there, held back the young miner. " Wait till the inner air becomes pure," said he. " Yes, look out for mephitical vapors !" cried Simon Ford. A quarter of an hour passed away in anxious suspense. The lantern, placed at the end of a rod, was then introduced into the excavation, and continued to burn with unaltered bril- liancy. "Go now, Harry," said James Starr; "we'll follow you." The opening made by the dynamite was more than sufficient for the passage of a man. Harry, the lantern in his hand, entered it without hesitation, and disappeared in the darkness. James Starr, Simon Ford and Madge waited motionless. One minute—which to them seemed endless —passed away. Harry did not reappear; he did not call out. Drawing near the opening, James Starr no longer saw even the light of his lamp, which should have illuminated this dark cavity. The stratum—had it then suddenly failed under Harry's feet? Had the young miner fallen into some fissure ? Could his voice no longer reach his companions ? The old overseer, unwilling to listen to a word from his companions, was going to enter the opening, when a light appeared, faint at first, but growing stronger by degrees, and Harry called out these words : "Come, Mr. Starr! Come, father! The way is clear into New Aberfoyle !" CHAPTER IX. THE NEW ABERFOYLE. If, by some superhuman power, engineers could raise like a block with a thickness of a thousand feet, all that portion of the earth's crust which supports this collection of lakes, rivers, gulfs and adjacent lands in tho counties of Stirling, Dumbarton, and Renfrew, they would find, under this enormous covering, an immense excavation, with which there is but one other worthy of comparison—the celebrated Mammoth Cave in Kentucky. This excavation was composed of several hundred caverns, of all forms and of all sizes. It might be called a bee-hive, with numerous stories of cells, capriciously disposed, but a hive constructed on an enormous shell, and which, instead of bees, might have served to lodge all the ichthyosaurus, the megatheriums and the pterodoctyls of the geological period ! A labyrinth of galleries, some higher than tho highest arches of cathedrals, others like naves, narrow and winding, some horizontal, others perpendicular or slanting in every direc- tion, united these caverns and permitted free communication between them. The pillars which sustained these arches bent in every way, the thick walls firmly fixed between the gal- leries, the naves themselves in this layer of secondary rocks, were made of sandstone and shale. But between these useless rocks, and powerfully pressed by them, lay rich veins of coal, as if the black blood of this strange mine had circulated through their inextricable out- work. These deposits were developed over an extent of forty miles from north to south, and they extended even under tho Northern Canal. The importance of this basin could only be ascertained by borings, but it would exceed that of the carboniferous beds of Cardiff, in Wales, and the deposits of Newcastle, in the County of Northumberland. It is necessary to add that the working of this mine is singularly facilitated, because, by an odd disposition of the secondary rocks, by an inexplicable withdrawal of mineral materials in the geological period when this mass solidified, nature itself had multiplied the galleries and tunnels of New Aberfoyle. Yes, nature alone ! One would have believed at first in the discovery of some works aban- doned centuries before. It was not so. Such riches would not have been left behind. Hu- man beings had never roamed through this portion of the substratum of Scotland, and it was nature which had thus made these works. But we repeat that no hypogeurn of the Egyptian epoch, no catacomb of the Roman epoch, could be compared with it—only the celebrated Mammoth Cave, which, in an extent of more than twenty miles, numbers two hundred and twenty-six avenues, eleven lakes, seven rivers, eight cataracts, thirty-two unfathomable depths and fifty-seven domes, of which some are suspended at a height of more than four hundred and fifty feet. Like this cave, New Aberfoyle was not the work of man, but the work of the Creator. Such was this vast domain of incalculable riches, of which the discovery was properly due to the old overseer. Ten years residence in the old mine, an unusual perseverance in search- ing, a strong faith sustained by marvelous mining instinct. All these qualities combined were necessary to success, there, where so many others had failed. Why were the bor- ings, undertaken by James Starr, during the last years of the works, stopped exactly at this limit, on the very frontier of the new mine ? That was due to chance, which plays a great part in searches of this kind. However, it happened there was, in the Scotch substratum, a sort of subterranean county, which only lacked, to make it habita- ble, either the rays of the sun, or lacking that, the light of a special star. Water existed here in certain depressions, forming vast ponds, or even lakes larger than Loch Katrine, situated exaetly overhead. Without doubt these lakes had not the movement of water, currents, or surf. They did not reflect the outlines of any old Gothic castle. Neither birch trees nor oaks hung over their banks ; mountains did not cast great shadows on their surface ; steamboats did not plow them ; no light was reflected in their waters ; the sun did not impregnate them with its glittering rays ; the moon did not rise on their horizon. Nevertheless, these deep lakes, whoso surface was unruffled by the breeze, vyould not have been without charms by the light of some electrical star, and united by a 2acing of canals, they well completed the geography of this strange domain. Although unfit for vegetation, the substratum might meanwhile serve as a dwelling place for a whole population. And who knows, in the midst of an even temperature, at the bottom of these Aberfoyle mines, as well as in those of Newcastle, Alloa, or of Cardiff, when their deposits will be exhausted—who knows but the poor class of the United Kingdom may some day there find a refuge ? CHAPTER X. GOING AND RETURNING. At the sound of Harry's voice, James Starr, Madge and Simon Ford entered by the narrow opening which brought the Dochart Pit into communication with the new mine. They found themselves at the rise of a rather large gallery. One would have thought that it had been pierced by man—that the pick and the mattock had emotied it for the working of a new deposit. The explorers asked themselves if, by a singular chance, they had not been taken into some ancient mine, of which the oldest miners in the county had never known the-, existence. No ; it was the geological layers which had,, escaped this gallery, during the epoch of the,-, piling up of the secondary formation. Perhaps some torrent had formerly rem through it, when the upper waters had minjte»i with the vegetable kingdom ; but now it was as dry as if it had been bored several thousand feet lower in the flooring of the gigantic rocks. At the same time the air circulated easily, indi- cating that certain natural vents put it in com- munication with the outer atmosphere. This observation, which was made by the engineer, was correct, and they knew that the ventilation would work easily in the new mine. As for the fire-damp, which scarcely burned through the schists of the wall, it seemed as if it had been contained in a simple pocket, now empty, and it was certain that the atmosphere of the gallery did not contain the least trace of it. However, as a precaution, Harry only took in the safety-lamp, which insured them a light for twelve hours. James Starr and his com- panions then experienced complete happiness. This was the entire satisfaction of their desires. Around them was nothing but coal. Emotion kept them silent. Even Simon Ford controlled himself. His joy was expressed, not by l«ng. sentences, but by short interjections. Perhaps it was imprudent of them to go so deep into the crypt. Pshaw ! They hardly dreamed of returning. The gallery was practicable, not very winding. No crevice barred the passage no shoot propogated bad ex- alations. There was nothing to stop them, and, for'one hour, James Starr, Madge, Harry and Simon Ford pursued their way without finding anything to indicate what was the exact direction of this unknown tunnel. Undoubtedly they would have gone still farther, had they not reached the end of this large road which they had followed since their entrance into the mine. The gallery ended in an enormous cavern, the height or depth of which they could not estimate. To what altitude rounded the arch of this excavation ? At what distance receded the opposite wall ? The shadows which filled it prevented any discovery. But by the lamp light the explorers could verify the fact, that this dome covered a vast extent of stagnant water, pond or lake, whose picturesque streams, tumbling overhigh rocks, were lost in the darkness. " Halt ! " cried Simon Ford, suddenly stop- ping. " One step farther and we may roll into some abyss ! " " Let us rest, my friends," said the engineer "We must soon think of returning to the cottage." " Our lamp will last us for ten hours yet, Mr. Starr," said Harry. " Well, let us rest," said James Starr. " I admit that my limbs need it ! And you Madge, don't you feel fatigued after such a long walk ? " " Not very much, Mr. James," said the ro- bust Scotchwoman. We have had the habit of exploring for whole days, the old Aberfoyle mine." "Pshaw!" added Simon Ford. "Madge could walk ten times the distance if it were ne- cessary ! But I want to know, Mr. James, it my communication was worth the trouble you have taken ? Say what you think, Mr. James, say what you think ! " "Ah, my old companion, it is a long time since I felt such joy !" replied the engineer. " The little we have explored of this marvel- ous mine seems to indicate that its extent is very considerable, at least in length." "In length .and in depth, also ! " replied Simon Ford. " We will find that out later." " And I, I am sure of it ! Remember my instinct as an old miner. It has never deceived me." " I would like to believe you, Simon," said
