There Peter stopped again abruptly, but with an air of finality. He had, so I gathered, told me all he was going to tell me about the mermaid. I had blundered badly in asking my question. I suppose that some note of unsympathetic scepticism in my tone suggested to Peter that I was inclined to laugh at him. I did my best to retrieve my position. I sat quite silent and stared at the peak of the mainsail. The block on the horse rattled occasionally. The sun’s rim touched the horizon. At last Peter was reassured and began again. “It was my mother told me about it, and she knew, for many’s the time she did be playing with the young lads, her being no more than a little girleen at the time. Seven of them there was, and the second eldest was the one age with my mother. That was after herself left him.” “Herself” was vague enough; but I did not venture to ask another question. I took my eyes off the peak of the mainsail and fixed them inquiringly on Peter. It was as near as I dared go to asking a question. “Herself,” said Peter, “was one of them ones.” He nodded sideways over the gunwale of the boat. The sea, though still calm, was beginning to be moved by that queer restlessness which comes on it at sunset. The tide eddied in mysteriously oily swirls. The rocks to the eastward of us had grown dim. A gull flew by overhead uttering wailing cries. The graceful terns had disappeared. A cormorant, flying so low that its wing-tips broke the water, sped across our bows to some far resting-place. I fell into a mood of real sympathy with stories about mermaids. I think Peter felt the change which had come over me. “Anthony O’Flaherty,” said Peter, “was a young man when he saw them first. It was in the little bay back west of the island, and my mother never rightly knew what he was doing there in the middle of the night; but there he was. It was the bottom of a low spring tide, and there’s rocks off the end of the bay that’s uncovered at the ebb of the springs. You’ve maybe seen them.” I have seen them, and Peter knew it well. I have seen more of them than I want to. There was an occasion when Peter and I lay at anchor in that bay, and a sudden shift of wind set us to beating out at three o’clock in the morning. The rocks were not uncovered then, but the waves were breaking fiercely over them. We had little room for tacking, and I am not likely to forget the time we went about a few yards to windward of them. The stretch of wild surf under our lee looked ghastly white in the dim twilight of the dawn. Peter knew what I was thinking. “It was calm enough that night Anthony O’Flaherty was there,” he said, “and there was a moon shining, pretty near a full moon, so Anthony could see plain. Well, there was three of them in it, and they playing themselves.” “Mermaids?”
