"But, Harry, how can we be sure that these two hands do not belong to the same body?"

"What can put such a notion in your head, Jack?" asked Harry.

"Well, I don't know. Creatures that live in these holes, Harry, don't you see? they can't be made like us, eh?"

"But they ARE just like us, Jack."

"Oh, no! don't say that, Harry! Perhaps some madman managed to get in for a time."

"A madman! No madman would have formed such connected plans, or done such continued mischief as befell us after the breaking of the ladders."

"Well, but anyhow he has done no harm for the last three years, either to you, Harry, or any of your people."

"No matter, Jack," replied Harry; "I am persuaded that this malignant being, whoever he is, has by no means given up his evil intentions. I can hardly say on what I found my convictions. But at any rate, for the sake of the new works, I must and will know who he is and whence he comes."

"For the sake of the new works did you say?" asked Jack, considerably surprised.

"I said so, Jack," returned Harry. "I may be mistaken, but, to me, all that has happened proves the existence of an interest in this mine in strong opposition to ours. Many a time have I considered the matter; I feel almost sure of it. Just consider the whole series of inexplicable circ.u.mstances, so singularly linked together. To begin with, the anonymous letter, contradictory to that of my father, at once proves that some man had become aware of our projects, and wished to prevent their accomplishment. Mr. Starr comes to see us at the Dochart pit. No sooner does he enter it with me than an immense stone is cast upon us, and communication is interrupted by the breaking of the ladders in the Yarrow shaft. We commence exploring. An experiment, by which the existence of a new vein would be proved, is rendered impossible by stoppage of fissures. Notwithstanding this, the examination is carried out, the vein discovered. We return as we came, a prodigious gust of air meets us, our lamp is broken, utter darkness surrounds us. Nevertheless, we make our way along the gloomy pa.s.sage until, on reaching the entrance, we find it blocked up. There we were--imprisoned. Now, Jack, don't you see in all these things a malicious intention? Ah, yes, believe me, some being hitherto invisible, but not supernatural, as you will persist in thinking, was concealed in the mine. For some reason, known only to himself, he strove to keep us out of it. WAS there, did I say? I feel an inward conviction that he IS there still, and probably prepares some terrible disaster for us. Even at the risk of my life, Jack, I am resolved to discover him."

Harry spoke with an earnestness which strongly impressed his companion.

"Well, Harry," said he, "if I am forced to agree with you in certain points, won't you admit that some kind fairy or brownie, by bringing bread and water to you, was the means of--"

"Jack, my friend," interrupted Harry, "it is my belief that the friendly person, whom you will persist in calling a spirit, exists in the mine as certainly as the criminal we speak of, and I mean to seek them both in the most distant recesses of the mine."

"But," inquired Jack, "have you any possible clew to guide your search?"

"Perhaps I have. Listen to me! Five miles west of New Aberfoyle, under the solid rock which supports Ben Lomond, there exists a natural shaft which descends perpendicularly into the vein beneath. A week ago I went to ascertain the depth of this shaft. While sounding it, and bending over the opening as my plumb-line went down, it seemed to me that the air within was agitated, as though beaten by huge wings."

"Some bird must have got lost among the lower galleries," replied Jack.

"But that is not all, Jack. This very morning I went back to the place, and, listening attentively, I thought I could detect a sound like a sort of groaning."

"Groaning!" cried Jack, "that must be nonsense; it was a current of air--unless indeed some ghost--"

"I shall know to-morrow what it was," said Harry.

"To-morrow?" answered Jack, looking at his friend.

"Yes; to-morrow I am going down into that abyss."

"Harry! that will be a tempting of Providence."

"No, Jack, Providence will aid me in the attempt. Tomorrow, you and some of our comrades will go with me to that shaft. I will fasten myself to a long rope, by which you can let me down, and draw me up at a given signal. I may depend upon you, Jack?"

"Well, Harry," said Jack, shaking his head, "I will do as you wish me; but I tell you all the same, you are very wrong."

"Nothing venture nothing win," said Harry, in a tone of decision.

"To-morrow morning, then, at six o'clock. Be silent, and farewell!"

It must be admitted that Jack Ryan's fears were far from groundless.

Harry would expose himself to very great danger, supposing the enemy he sought for lay concealed at the bottom of the pit into which he was going to descend. It did not seem likely that such was the case, however.

"Why in the world," repeated Jack Ryan, "should he take all this trouble to account for a set of facts so very easily and simply explained by the supernatural intervention of the spirits of the mine?"

But, notwithstanding his objections to the scheme, Jack Ryan and three miners of his gang arrived next morning with Harry at the mouth of the opening of the suspicious shaft. Harry had not mentioned his intentions either to James Starr or to the old overman. Jack had been discreet enough to say nothing.

Harry had provided himself with a rope about 200 feet long. It was not particularly thick, but very strong--sufficiently so to sustain his weight. His friends were to let him down into the gulf, and his pulling the cord was to be the signal to withdraw him.

The opening into this shaft or well was twelve feet wide. A beam was thrown across like a bridge, so that the cord pa.s.sing over it should hang down the center of the opening, and save Harry from striking against the sides in his descent.

He was ready.

"Are you still determined to explore this abyss?" whispered Jack Ryan.

"Yes, I am, Jack."

The cord was fastened round Harry's thighs and under his arms, to keep him from rocking. Thus supported, he was free to use both his hands. A safety-lamp hung at his belt, also a large, strong knife in a leather sheath.

Harry advanced to the middle of the beam, around which the cord was pa.s.sed. Then his friends began to let him down, and he slowly sank into the pit. As the rope caused him to swing gently round and round, the light of his lamp fell in turns on all points of the side walls, so that he was able to examine them carefully. These walls consisted of pit coal, and so smooth that it would be impossible to ascend them.

Harry calculated that he was going down at the rate of about a foot per second, so that he had time to look about him, and be ready for any event.

During two minutes--that is to say, to the depth of about 120 feet, the descent continued without any incident.

No lateral gallery opened from the side walls of the pit, which was gradually narrowing into the shape of a funnel. But Harry began to feel a fresher air rising from beneath, whence he concluded that the bottom of the pit communicated with a gallery of some description in the lowest part of the mine.

The cord continued to unwind. Darkness and silence were complete. If any living being whatever had sought refuge in the deep and mysterious abyss, he had either left it, or, if there, by no movement did he in the slightest way betray his presence.

Harry, becoming more suspicious the lower he got, now drew his knife and held it in his right hand. At a depth of 180 feet, his feet touched the lower point and the cord slackened and unwound no further.

Harry breathed more freely for a moment. One of the fears he entertained had been that, during his descent, the cord might be cut above him, but he had seen no projection from the walls behind which anyone could have been concealed.

The bottom of the abyss was quite dry. Harry, taking the lamp from his belt, walked round the place, and perceived he had been right in his conjectures.

An extremely narrow pa.s.sage led aside out of the pit. He had to stoop to look into it, and only by creeping could it be followed; but as he wanted to see in which direction it led, and whether another abyss opened from it, he lay down on the ground and began to enter it on hands and knees.

An obstacle speedily arrested his progress. He fancied he could perceive by touching it, that a human body lay across the pa.s.sage. A sudden thrill of horror and surprise made him hastily draw back, but he again advanced and felt more carefully.

His senses had not deceived him; a body did indeed lie there; and he soon ascertained that, although icy cold at the extremities, there was some vital heat remaining. In less time than it takes to tell it, Harry had drawn the body from the recess to the bottom of the shaft, and, seizing his lamp, he cast its lights on what he had found, exclaiming immediately, "Why, it is a child!"

The child still breathed, but so very feebly that Harry expected it to cease every instant. Not a moment was to be lost; he must carry this poor little creature out of the pit, and take it home to his mother as quickly as he could. He eagerly fastened the cord round his waist, stuck on his lamp, clasped the child to his breast with his left arm, and, keeping his right hand free to hold the knife, he gave the signal agreed on, to have the rope pulled up.

It tightened at once; he began the ascent. Harry looked around him with redoubled care, for more than his own life was now in danger.

For a few minutes all went well, no accident seemed to threaten him, when suddenly he heard the sound of a great rush of air from beneath; and, looking down, he could dimly perceive through the gloom a broad ma.s.s arising until it pa.s.sed him, striking him as it went by.

It was an enormous bird--of what sort he could not see; it flew upwards on mighty wings, then paused, hovered, and dashed fiercely down upon Harry, who could only wield his knife in one hand. He defended himself and the child as well as he could, but the ferocious bird seemed to aim all its blows at him alone. Afraid of cutting the cord, he could not strike it as he wished, and the struggle was prolonged, while Harry shouted with all his might in hopes of making his comrades hear.
