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 r閟um？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 314 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.
