There his declaration was received. His account was given so clearly that it could not be doubted. Sir William Elphiston, President of the Royal Institution, and not only colleague, but a personal friend of Starr's, was also informed, and asked to direct the search which was to be made without delay in the mine. Several men were placed at his disposal, supplied with lamps, picks, long rope ladders, not forgetting provisions and cordials. Then guided by Jack Ryan, the party set out for the Aberfoyle mines.

The same evening the expedition arrived at the opening of the Yarrow shaft, and descended to the twenty-seventh landing, at which Jack Ryan had been stopped a few hours previously. The lamps, fastened to long ropes, were lowered down the shaft, and it was thus ascertained that the four last ladders were wanting.

As soon as the lamps had been brought up, the men fixed to the landing a rope ladder, which unrolled itself down the shaft, and all descended one after the other. Jack Ryan's descent was the most difficult, for he went first down the swinging ladders, and fastened them for the others.

The space at the bottom of the shaft was completely deserted; but Sir William was much surprised at hearing Jack Ryan exclaim, "Here are bits of the ladders, and some of them half burnt!"

"Burnt?" repeated Sir William. "Indeed, here sure enough are cinders which have evidently been cold a long time!"

"Do you think, sir," asked Ryan, "that Mr. Starr could have had any reason for burning the ladders, and thus breaking of communication with the world?"

"Certainly not," answered Sir William Elphiston, who

had become very thoughtful. "Come, my lad, lead us to the cottage. There we shall ascertain the truth."

Jack Ryan shook his head, as if not at all convinced. Then, taking a lamp from the hands of one of the men, he proceeded with a rapid step along the principal passage of the Dochart pit. The others all followed him.

In a quarter of an hour the party arrived at the excavation in which stood Simon Ford's cottage. There was no light in the window. Ryan darted to the door, and threw it open. The house was empty.

They examined all the rooms in the somber habitation. No trace of violence was to be found. All was in order, as if old Madge had been still there. There was even an ample supply of provisions, enough to last the Ford family for several days.

The absence of the tenants of the cottage was quite unaccountable. But was it not possible to find out the exact time they had quitted it? Yes, for in this region, where there was no difference of day or night, Madge was accustomed to mark with a cross each day in her almanac.

The almanac was pinned up on the wall, and there the last cross had been made at the 6th of December; that is to say, a day after the arrival of James Starr, to which Ryan could positively swear. It was clear that on the 6th of December, ten days ago, Simon Ford, his wife, son, and guest, had quitted the cottage. Could a fresh exploration of the mine, undertaken by the engineer, account for such a long absence? Certainly not.

It was intensely dark all round. The lamps held by the men gave light only just where they were standing. Suddenly Jack Ryan uttered a cry. "Look there, there!"

His finger was pointing to a tolerably bright light, which was moving about in the distance. "After that light, my men!" exclaimed Sir William.

"It's a goblin light!" said Ryan. "So what's the use? We shall never catch it."

The president and his men, little given to superstition, darted off in the direction of the moving light. Jack Ryan, bravely following their example, quickly overtook the head-most of the party.

It was a long and fatiguing chase. The lantern seemed to be carried by a being of small size, but singular agility.

Every now and then it disappeared behind some pillar, then was seen again at the end of a cross gallery. A sharp turn would place it out of sight, and it seemed to have completely disappeared, when all at once there would be the light as bright as ever. However, they gained very little on it, and Ryan's belief that they could never catch it seemed far from groundless.
