He was still sleeping when the queen rose and dressed herself, to make everything ready for her husband's journey; and the first place she went to was the stable, where she fed and watered the shaggy brown horse and put the saddle on it. Most people thought this saddle was of wood, and did not see the little sparkles of gold and silver that were hidden in it. She strapped it lightly on the horse's back, and then led it down before the house, where the king waited.
'Good luck to you, and victories in all your battles,' she said, as she kissed him before he mounted. 'I need not be telling you anything. Take the advice of the horse, and see you obey it.'
So he waved his hand and set out on his journey, and the wind was not swifter than the brown horse--no, not even the March wind which raced it and could not catch it. But the horse never stopped nor looked behind, till in the dark of the night he reached the castle of the king of the oak windows.
'We are at the end of the journey,' said the horse, 'and you will find the Sword of Light in the king's own chamber. If it comes to you without scrape or sound, the token is a good one. At this hour the king is eating his supper, and the room is empty, so none will see you. The sword has a knob at the end, and take heed that when you grasp it, you draw it softly out of its sheath. Now go! I will be under the window.'
Stealthily the young man crept along the passage, pausing now and then to make sure that no man was following him, and entered the king's chamber. A strange white line of light told him where the sword was, and crossing the room on tiptoe, he seized the knob, and drew it slowly out of the sheath. The king could hardly breathe with excitement lest it should make some noise, and bring all the people in the castle running to see what was the matter.
But the sword slid swiftly and silently along the case till only the point was left touching it. Then a low sound was heard, as of the edge of a knife touching a silver plate, and the king was so startled that he nearly dropped the knob.
'Quick! quick!' cried the horse, and the king scrambled hastily through the small window, and leapt into the saddle.
'He has heard and he will follow,' said the horse; 'but we have a good start,' And on they sped, on and on, leaving the winds behind them.
At length the horse slackened its pace. 'Look and see who is behind you,' it said; and the young man looked.
'I see a swarm of brown horses racing madly after us,' he answered.
'We are swifter than those,' said the horse, and flew on again.
'Look again, O king! Is anyone coming now?'
'A swarm of black horses, and one has a white face, and on that horse a man is seated. He is the king of the oak windows.'
'That is my brother, and swifter still than I,' said the horse, 'and he will fly past me with a rush. Then you must have your sword ready, and take off the head of the man who sits on him, as he turns and looks at you. And there is no sword in the world that will cut off his head, save only that one.'
'I will do it,' replied the king; and he listened with all his might, till he judged that the white-faced horse was close to him. Then he sat up very straight and made ready.
The next moment there was a rushing noise as of a mighty tempest, and the young man caught a glimpse of a face turned towards him.
Almost blindly he struck, not knowing whether he had killed or only wounded the rider. But the head rolled off, and was caught in the brown horse's mouth.
'Jump on my brother, the black horse, and go home as fast as you can, and I will follow as quickly as I may,' cried the brown horse; and leaping forward the king alighted on the back of the black horse, but so near the tail that he almost fell off again.
But he stretched out his arm and clutched wildly at the mane and pulled himself into the saddle.
Before the sky was streaked with red he was at home again, and the queen was sitting waiting till he arrived, for sleep was far from her eyes. Glad was she to see him enter, but she said little, only took her harp and sang softly the songs which he loved, till he went to bed, soothed and happy.
It was broad day when he woke, and he sprang up saying:
'Now I must go to the Gruagach, to find out if the spells he laid on me are loose.'
'Have a care,' answered the queen, 'for it is not with a smile as on the other days that he will greet you. Furiously he will meet you, and will ask you in his wrath if you have got the sword, and you will reply that you have got it. Next he will want to know how you got it, and to this you must say that but for the knob you had not got it at all. Then he will raise his head to look at the knob, and you must stab him in the mole which is on the right side of his neck; but take heed, for if you miss the mole with the point of the sword, then my death and your death are certain.
He is brother to the king of the oak windows, and sure will he be that the king must be head, or the sword would not be in your hands.' After that she kissed him, and bade him good speed.
'Didst thou get the sword?' asked the Gruagach, when they met in the usual place.
'I got the sword.'
'And how didst thou get it?'
'If it had not had a knob on the top, then I had not got it,' answered the king.
'Give me the sword to look at,' said the Gruagach, peering forward; but like a flash the king had drawn it from under his nose and pierced the mole, so that the Gruagach rolled over on the ground.
'Now I shall be at peace,' thought the king. But he was wrong, for when he reached home he found his servants tied together back to back with cloths bound round their mouths, so that they could not speak. He hastened to set them free, and he asked who had treated them in so evil a manner.
'No sooner had you gone than a great giant came, and dealt with us as you see, and carried off your wife and your two horses,' said the men.
'Then my eyes will not close nor will my head lay itself down till I fetch my wife and horses home again,' answered he, and he stopped and noted the tracks of the horses on the grass, and followed after them till he arrived at the wood, when the darkness fell.
