The next road was smooth and broad, and it ran straight and level across the plain. It looked so easy a way that Thomas wondered that anyone ever wanted to go along the narrow path at all.

The third road wound along a hillside, and the banks above it and below it were covered with beautiful brackens, and their delicate fronds rose high on either side, so high, indeed, that they would shelter the wayfarer from the burning heat of the noonday sun.

"That is the best road of all," thought Thomas to himself; "it looks so fresh and cool, I should like to travel along it."

Then the lady's voice sounded in his ears. "Seest thou that narrow path," she asked, "all set about with thorns and briars? That is the Path of Righteousness, and there be but few, oh, so few! who ever ask where it leads to, or who try to travel by it. And seest thou that broad, broad road, that runs so smoothly across the desert? That is the Path of Wickedness, and I trow it is a pleasant way, and easy to travel by. Men think it so, at least, and, poor fools, they do not trouble to ask where it leads to. Some would fain persuade themselves that it leads to Heaven, but Heaven was never reached by an easy road. 'Tis the narrow road through the briars and thorns that leads us thither, and wise are the men who follow it. And seest thou that bonnie, bonnie road, that winds up round the ferny brae? That is the way to Fairyland, and that is the road which lies before us."

Here Thomas was about to speak, and to remonstrate with her for carrying him away, but she interrupted him.

"Hush," she said, "thou must be silent now, Thomas; the time for speech is past. Thou art on the borders of Elfland, and if ever mortal man speak a word in Elfland, he can nevermore go back to his own country."

So Thomas held his peace, and climbed sadly on the palfrey's back, and once more they started on their awful journey. On and on they went. The beautiful road through the ferns was soon left behind, and great mountains had to be crossed, and steep, narrow valleys, until at last, far away in the distance, a splendid castle appeared, standing on the top of a high hill.

It was built of pure white marble, with massive towers, and lovely gardens stretched in front of it.

"That castle is mine," said the lady proudly. "It belongs to me, and to my husband, who is the King of this country. He is a jealous man, and one greatly to be feared, and, if he knew how friendly thou and I have been, he would kill thee in his rage. Remember, therefore, what I told thee about keeping silence. Thou canst talk to me, an thou wilt, if an opportunity offers, but see to it that thou answerest no one else. There are knights and squires in abundance at my husband's court, and doubtless they would fain question thee about the country from whence thou art come, but thou must pay no heed to them, and I shall pretend that thou talkest in an unknown tongue, and that I learned to understand it in thine own country."

While she was speaking, Thomas was amazed to see that a great change had passed over her again. Her face grew bright, and her gray gown vanished, and the green mantle took its place, and once more she became the beauteous being who had charmed his eyes at the Huntly Burn. And he was still more amazed when, on looking down, he found that his own raiment was changed too, and that he was now dressed in a suit of soft, fine cloth, and that on his feet he wore velvet shoon.
