When the door had closed on the Royal Dragon, King Terribus turned again to Prince Marvel, while his crimson face glowed with embarrassment, and his front eye rolled with baffled rage as he thought how vain had been all his efforts to kill this impudent invader of his domains.  
But his powers were by no means exhausted. He was a mighty king--the mightiest of all in the Enchanted Island, he believed--and ways to destroy his enemies were numerous.
 
"Send for a hundred of my Gray Men!" he suddenly cried; and a courtier ran at once to summon them. The Gray Men would obey his orders without question, he well knew. They were silent, stubborn, quick, and faithful to their king. Terribus had but to command and his will would be obeyed.
 
They entered the room so quietly that Nerle never knew they were there until he turned and found the hundred gray ones standing close together in the center of the hall. Then Prince Marvel came to Nerle's side and whispered something in his ear.
 
"Will you obey my orders?" they heard the king ask. And the Gray Men, with their eyes fixed upon their master, nodded all their hundred heads and put their hands upon the dangerous three-tined forks that were stuck in every one of the hundred belts.
 
Prince Marvel handed one end of a coiled rope to Nerle, and then they both sprang forward and ran around the spot where the hundred Gray Men stood huddled together. Then they were pulled closer together than before--closer, and still closer--for the prince and Nerle had surrounded them with the rope and were tying the two ends together in a tight knot. The rope cut into the waists of those on the outside, and they pressed inward against their fellows until there was scarcely space to stick a knife-blade between any two of them. When the prince had tied the rope firmly King Terribus, who had been looking on amazed, saw that his hundred Gray Men were fastened together like a bundle of kindling-wood, and were unable to stir hand or foot.
 
And, while he still gazed open-mouthed at the strange sight, Prince Marvel tilted the bundle of men up on its edge and rolled it out of the door. It went rolling swiftly through the courtyard and bounded down the castle steps, where the rope broke and the men fell sprawling in all directions on the marble walk.
 
King Terribus sighed, for such treatment of his Gray Men, whom he dearly loved, made him very unhappy.
 
But more than ever was he resolved to kill these impudent strangers, who, in the very heart of his kingdom where thousands bowed to his will, dared openly defy his power. So, after a moment's thought, Terribus beckoned to a dwarf who, robed in gay and glittering apparel, stood near his throne.
 
"Summon the royal Dart Slingers!" he said, with a scowl.
 
The little man bowed and hastened away, to return presently with twenty curiously crooked dwarfs, each armed with a sling and a quiver full of slender, sharp-pointed darts.
 
"Slay me these strangers!" exclaimed the king, in his gruffest voice.
 
Now Nerle, when he beheld these terrible Dart Slingers, of whom he had heard many tales in his boyhood, began to shiver and shake with fright, so that his teeth rattled one upon another. And he reflected: "Soon shall I be content, for these darts will doubtless pierce every part of my body."
 
The dwarfs formed a line at one side of the gloomy throne-room, and Prince Marvel, who had been earnestly regarding them, caught Nerle by the arm and led him to the opposite wall.
 
"Stand close behind me and you will be safe," he whispered to his esquire.
 
Then each dwarf fixed a dart in his sling, and at a word from their chief they all drew back their arms and launched a shower of the sharp missiles at the strangers.
 
Swift and true they sped, each dart intended to pierce the body of the youthful knight who stood so calm before them. Prince Marvel had raised his right arm, and in his hand was a small leather sack, with a wide mouth. As the darts flew near him a strange thing happened: they each and all swerved from their true course and fell rattling into the leathern sack, to the wonder of the royal slingers and the dismay of King Terribus himself.
 
"Again!" screamed the king, his usually mild voice hoarse with anger.
 
So again the dwarfs cast their darts, and again the leathern sack caught them every one. Another flight followed, and yet another, till the magic sack was packed full of the darts and not a dwarf had one remaining in his quiver.
 
Amid the awed silence of the beholders of this feat the merry laughter of Prince Marvel rang loud and clear; for the sight of the puzzled and terrified faces about him was very comical. Plucking a dart from the sack he raised his arm and ............
