Of all the different kinds of goblins that haunted the lonely places of Ireland in days of old, air-demons¹ were most dreaded² by the people. They lived among clouds, and mists, and rocks, and they hated the human race with the utmost malignity³. In those times lived in the north of Desmond (the present county of Cork) a man man named Fergus O'Mara. His farm lay on the southern slope of the Ballyhoura Mountains, along which[113] ran the open road that led to his house. This road was not shut in by walls or fences; but on both sides there were scattered⁴ trees and bushes that sheltered it in winter, and made it dark and gloomy when you approached the house at night. Beside the road, a little way off from the house, there was a spot that had an evil name all over the country, a little hill covered closely with copsewood, with a great craggy rock on top, from which, on stormy nights, strange and fearful sounds had often been heard—shrill voices, and screams, mingled⁵ with loud fiendish laughter; and the people believed that it was the haunt of air-demons. In some way it had become known that these demons had an eye on Fergus, and watched for every opportunity to get him into their power. He had himself been warned of this many years before, by an old monk⁶ from the neighbouring monastery⁷ of Buttevant, who told him, moreover,[114] that so long as he led a blameless, upright life, he need have no fear of the demons; but that if ever he yielded to temptation or fell into any great sin, then would come the opportunity for which they were watching day and night. He never forgot this warning, and he was very careful to keep himself straight, both because he was naturally a good man, and for fear of the air-demons.
