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 passing 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 passed. 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 passage 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 passage. 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.
