the Fairy Dog

In the course of another conversation, he pointed to a rocky knoll in a fiedd not far from his home, and said, "I saw a dog with a white ring around his neck by that hill there, and the oldest men round Galway have seen him too, for he has been here one hundred years or more. He is a dog of the good people, and only appears at certain times of the night."
