“The marksman took a cautious aim.

“‘Bang!’ A crash of glass, a fierce yell.

“‘Oh, Captain!’ cried Teague, with a wild shout, that made the night tremble. The Rapparees burst in on the startled revellers. But, as the latter had their weapons ready to hand, a desperate conflict ensued, and it is said that, until the last of his followers was slain, Garroid Jarla remained sitting where he had been shot, and that his face was black as coal, while his eyes gleamed like fire. The Rapparees sacked the castle before they left for Cluin-Kyle with the news of the tyrant’s death.

“The next day the peasantry entered the ruined castle, and, finding the body of their arch-enemy, Garroid Jarla, they dragged it to the Ford of Dysartgallen, and, having cut it in quarters, they flung them into the river, and believed they had got rid, once and for all, of the ruthless tyrant of their homes.

“But in this, according to Terry’s story,” said the doctor, “they were mistaken. For, time after time, Garroid Jarla appeared at the very spot where he used to meet travellers during his life, and whomever he accosted never saw the morning break again.

“At last a friar coming this way heard of the apparitions and their fatal results, and he bade the people bring a stone trough, and place it on the spot, and this trough was fed with water from a running stream, and the friar blessed the water, so that no evil spirit could come near it. And after this, for generations, no one ever saw the ghost of Garroid Jarla. But in the dark days of Ninety-eight, a band of Yeos, coming along the road, broke the trough, and turned away the stream from it, and ever since then it is dry, and of no service to man or beast, and ever since then at irregular intervals, but always on Christmas Eve, the ghost reappears and claims a victim, and when he appears a light burns on the Knock. And that is Terry’s story,” said the doctor, and he shook the ashes from his pipe.

“Have you ever seen the ghost?” I asked.

“I have seen the light on the Knock,” he replied, “and I have seen the dead men. You saw the light on the Knock to-night; you also have seen a dead man. Do you doubt,” said he, looking me straight in the face, “that he is one of Garroid Jarla’s victims?”

“Perhaps, after all, doctor,” said I, “there are more things in heaven and earth than are dreamt of in our philosophy.”

“It is getting late,” said the doctor, “and I am sure you must be tired.”
