When they are friendly to a man they give him help in his work, putting their strength into his body. Or they may tell him where to find treasure, hidden gold; or through certain wise men or women who have learned from them or can ask and get their knowledge they will tell where cattle that have strayed may be found, or they will cure the sick or tell if a sickness is not to be cured. They will sometimes work as if against their own will or intention, giving back to the life of our world one who had received the call to go over to their own. They call many there, summoning them perhaps through the eye of a neighbour, the evil eye, or by a touch, a blow, a fall, a sudden terror. Those who have received their touch waste away from this world, lending their strength to the invisible ones; for the strength of a human body is needed by the shadows, it may be in their fighting, and certainly in their hurling to win the goal. Young men are taken for this, young mothers are taken that they may give the breast to newly born children among the Sidhe, young girls that they may themselves become mothers there. While these are away a body in their likeness, or the likeness of a body, is left lying in their place. They may be given leave to return to their village after a while, seven years it may be, or twice or three times seven. But some are sent back only at the end of the years allotted them at the time of their birth, old spent men and women, thought to have been dead a long time, given back to die and be buried on the face of the earth. There are two races among the Sidhe. One is tall and handsome, gay, and given to jesting and to playing pranks, leading us astray in the fields, giving gold that turns to withered leaves or to dust. These ride on horses through the night-time in large companies and troops, or ride in coaches, laughing and decked with flowers and fine clothes. The people of the other race are small, malicious, wide-bellied, carrying before them a bag. When a man or woman is about to die, a woman of the Sidhe will sometimes cry for a warning, keening and making lamentation. At the hour of death fighting may be heard in the air or about the house--that is, when the man in danger has friends among the shadows, who are fighting on his behalf.
