One day Arthur dressed himself in his best armor, mounted his best horse and rode forth alone to seek adventure. He had started before dawn and had ridden slowly along.

Just at day-break he saw Merlin running toward him in deadly peril, for three fierce vagabonds brandishing huge clubs were close at his heels. Arthur rode toward the robbers, and they turned and fled at the sight of an armed knight.

"O, Merlin," said Arthur, "this time certainly you would have been killed in spite of your magic if I had not appeared to rescue you."

"No," said Merlin, "I could have saved myself if I had wished; but you are nearer death than I am, for now you are certainly traveling toward death unless God befriend you."

Arthur asked the magician what he meant, but the wily man would give no explanation. However, he turned and accompanied Arthur.

As they rode along they came across a beautiful wayside spring, near which, under a wide-spreading tree, a rich tent was set. In front of it sat a sturdy knight full armed for battle.

"Sir Knight," said Arthur, "why do you sit here in full armor thus watching the road?"

"It is my custom," said the knight, "and no man may pass by unless he fight with me."

"That is a vile custom," said the king, "and I bid you give it up."

"That will I not do," said the knight. "If any man does not like my custom, let him change it."

"I will change it," said Arthur.

"I will defend myself," answered the knight.

Then the knight arose, took shield and spear, mounted the war-horse tethered near and rode at Arthur, who spurred his horse to meet the shock. They came together with such force that their horses were thrown back upon their haunches and their spears were shivered against their shields. Arthur recovered himself and pulled out his sword.

"No, no," said the knight, "I pray you let us fight again with spears.
It is the fairer way."

"I would be very willing," assented Arthur, "if I had another spear."

"But I have spears for both," declared the knight, as he called to a squire to bring him two good spears.

When the weapons were brought Arthur selected one and the knight took the other. Drawing apart they again charged together, and again their spears were both broken at the hand. Again Arthur put his hand to his sword, but the knight protested a second time.

"Nay, not so," he said, "for the honor of our knighthood let us joust once more. You are the strongest knight and the best jouster I have ever met."

"I am willing," said Arthur, "if you will let me have another spear."

Two more spears were brought—heavy ones such as only the best of knights could handle. Again Arthur chose the one he liked, and again they drew apart.

This time they ran together with greater force than ever, and once more Arthur shivered his spear on the shield of his opponent. But this time the spear of the unknown knight struck Arthur's shield full in the center and drove both horse and rider to the earth.

The king sprang free from his horse, recovered his shield, drew his sword and cried, "Now will I fight you on foot, for I have lost the honor on horseback."

"No, I will fight only on horseback," said the knight.

Then Arthur grew very angry and rushed afoot at the knight. Seeing how determined the king was, and thinking it dishonorable to keep his seat while Arthur fought on foot, the knight alighted and dressed his shield against his foe.

Long and fierce was the battle, for both were full of anger and resentment. They charged and fell back; they hacked and hewed until shields and armor were bent and broken in many places. Both were sorely wounded, and the blood ran until the trampled ground was stained with it. Then, out of breath and weary from the terrible exertion, they both rested for a few moments, but they soon began the duel again, rushing together like two fierce wild animals and striking such blows that both were many times brought to their knees. Every time, however, they recovered themselves and renewed the terrific struggle. At last the swords met full in the air, and Arthur's was broken at the hilt.

"Now yield," said the strange knight, "for you are wholly in my power and I can slay or release you as I will. Yield now to me as a recreant knight or I will slay you as you stand."

"As for death," said Arthur, "let it come when it will. I would rather die than shame my manhood by yielding."

And then like lightning Arthur leaped upon the knight, clasped him round the middle and threw him to the ground. But the knight was a powerful man, and throwing Arthur off he hurled him to the ground, struck off his helm and raised his sword to behead the king.

All the time Merlin had stood and watched the fray, but when he saw the deadly peril in which Arthur lay, he called out, "Knight, hold your hand! If you slay this knight you put this kingdom in the greatest peril, for this is a more worshipful knight than you dream of."

"Why, who is he?" asked the knight.

"It is King Arthur," Merlin replied.

Then was the knight fearful of the vengeance of the King, if he should survive the encounter. He raised his sword again and would have killed Arthur as he lay, but Merlin cast an enchantment over him and he fell into a deep sleep.

The magician caught up the king and rode forth on the knight's horse.

"Alas!" said Arthur, "what have you done, Merlin? Have you slain this good knight by your crafts? There is no braver knight in the world than he was. I would give half my kingdom if he were alive again."

"Do not trouble yourself," replied Merlin. "He is in less danger than you are, for he lies asleep and will awake whole and refreshed in three hours. I told you how powerful a knight he was, and you would have certainly been slain here if I had not been by to help. This same knight shall live to do you great service."

"Who is the knight?" asked Arthur.

"It is King Pellinore; and he shall have two sons, both of whom shall be good men; and one shall have no equal in strength, courage and goodness."
