"Follow me," said the king of the fairies, and away they went across the Irish Ocean, every mother's son of them astride his ragwort. Macuga (Cook) did not know on earth how he would return to his native land, but he leapt upon the ragwort as he saw the fairies do, and he called as he heard them call, and in an instant he was back in Arran. But he had got enough of the fairies on this trip itself, and he never went with them again.' The fairies were wont to take away infants and their mothers, and many precautions were taken to safeguard them till purification and baptism took place, when the fairy power became ineffective. Placing iron about the bed, burning leather in the room, giving mother and child the milk of a cow which had eaten of the _mothan_, pearl-wort (_Pinguicula vulgaris_), a plant of virtue, and similar means were taken to ensure their safety. If the watching-women neglected these precautions, the mother or child or both were spirited away to the fairy bower. Many stories are current on this subject. Sometimes the fairies helped human beings with their work, coming in at night to finish the spinning or the house-work, or to thresh the farmer's corn or fan his grain. On such occasions they must not be molested nor interfered with, even in gratitude. If presented with a garment they will go away and work no more. This method of getting rid of them is often resorted to, as it is not easy always to find work for them to do. _Bean chaol a chot uaine 's na gruaige buidhe_, 'the slender woman of the green kirtle and of the yellow hair,' is wise of head and deft of hand. She can convert the white water of the rill into rich red wine and the threads of the spiders into a tartan plaid. From the stalk of the fairy reed she can bring the music of the lull of the peace and of the repose, however active the brain and lithe the limb; and she can rouse to mirth and merriment, and to the dance, men and women, however dolorous their condition. From the bower could be heard the pipe and the song and the voice of laughter as the fairies 'sett' and reeled in the mazes of the dance. Sometimes a man hearing the merry music and seeing the wonderful light within would be tempted to go in and join them, but woe to him if he omitted to leave a piece of iron at the door of the bower on entering, for the cunning fairies would close the door and the man would find no egress. There he would dance for years--but to him the years were as one day--while his wife and family mourned him as dead.
