The ancient rath, or fort, or liss, generally enclosed about half an acre, and had two or more ramparts, formed by the heads of the tribe for defence. But when the race of the chieftains died out, then the Sidhe crowded into the forts, and there held their councils and revels and dances; and if a man put his ear close to the ground at night he could hear the sweet fairy music rising up from under the earth.

The rath ever after is sacred to the fairies, and no mortal is allowed to cut down a tree that grows on it, or to carry away a stone. But dangerous above all would it be to build on a fairy rath. If a man attempted such a rash act, the fairies would put a blast on his eyes, or give him a crooked mouth; for no human hand should dare to touch their ancient dancing grounds.

The Sidhe passionately love beauty and luxury, and hold in contempt all the mean virtues of thrift and economy. Above all143 things they hate the close, niggard hand that gathers the last grain, and drains the last drop in the milk-pail, and plucks the trees bare of fruit, leaving nothing for the spirits who wander by in the moonlight. They like food and wine to be left for them at night, yet they are very temperate; no one ever s............
