The Fisherman's Son and the Gruagach of Tricks
There was an old fisherman once in Erin who had a wife and one son.
The old fisherman used to go about with a fishing-rod and tackle to the rivers and lochs and every place where fish resort, and he was killing salmon and other fish to keep the life in himself and his wife and son.
The son was not so keen nor so wise as another, and the father was instructing him every day in fishing, so that if himself should be taken from the world, the son would be able to support the old mother and get his own living.
One day when the father and son were fishing in a river near the sea, they looked out over the water and saw a small dark speck on the waves. It grew larger and larger, till they saw a boat, and when the boat drew near they saw a man sitting in the stern of it.
There was a nice beach near the place where they were fishing. The man brought the boat straight to the beach, and stepping out drew it up on the sand.
They saw then that the stranger was a man of high degree (duine uasal).
After he had put the boat high on the sand, he came to where the two were at work, and said: "Old fisherman, you'd better let this son of yours with me for a year and a day, and I will make a very wise man of him. I am the Gruagach na g-cleasan (Gruagach of tricks), and I'll bind myself to be here with your son this day year."
"I can't let him go," said the old fisherman, "till he gets his mother's advice."
"Whatever goes as far as women I'll have nothing to do with," said the Gruagach. "You had better give him to me now, and let the mother alone."
They talked till at last the fisherman promised to let his son go for the year and a day. Then the Gruagach gave his word to have the boy there at the seashore that day year.
The Gruagach and the boy went into the boat and sailed away.
When the year and a day were over, the old fisherman went to the same place where he had parted with his son and the Gruagach, and stood looking over the sea, thinking would he see his son that day.
At last he saw a black spot on the water, then a boat.
