"Tush, boy; promise must yield to need," said the Knight of the Crested Boar. "The galleys of Diephold of Acerra even now ride in the Cala port, and think'st thou I will yield thee to his guidance? Come! At the palace wait decrees and grants which thou must sign for me ere the Aloe-stalk shall say us nay." "Must!" cried the boy, as an angry flush covered his face; "who sayeth '_must_' to the son of Henry the Emperor? Who sayeth 'must' to the grandson of Barbarossa? Stand off, churl of Kapparon! To me, Sicilians all! To me, sons of the Prophet!" and, breaking away from the grasp of the burly knight, young Frederick of Hohenstaufen dashed across the small stone bridge that led to the marble pavilion in the little lake. But only Abderachman the Saracen crossed to him. The wrath of the Knight of Kapparon was more dreaded than the commands of a little captive king. The burly baron laughed a mocking laugh. "Well blown, _ser Sirocco_!"[Q] he said, insolently, "but for all that, your Mightiness, I fear me, must bide with me, churl though I be. Come, we waste words!" and he moved toward the lad, who stood at bay upon the little bridge. Young Frederick slipped his falcon's leash. "Cross at thy peril, Baron Kapparon!" he cried; "one step more, and I unhood my falcon and send him straight to thy disloyal eyes. Ware the bird! His flight is certain, and his pounce is sharp!" The boy's fair face grew more defiant as he spoke, and William of Kapparon, who knew the young lad's skill at falconry, hesitated at the threat. But as boy and baron faced each other in defiance, there was another stir of the citron hedge, and another rush of hurrying hoofs. A second armed band closed in upon the scene, and a second knightly leader sprang to the ground. A snow-white plume trailed over the new-comer's crest, and on his three-cornered shield was blazoned a solitary aloe-stalk, sturdy, tough, and unyielding. "Who threatens the King of Sicily?" he demanded, as, sword in hand, he stepped upon the little bridge. The German baron faced his new antagonist. "So! is it thou, Count Diephold; is it thou, Aloe of Acerra?" he said. "By what right dar'st thou to question the Baron of Kapparon, guardian of the king, and Chief Captain of Sicily?" "'Guardian,' forsooth! 'Chief Captain,' say'st thou?" cried the Count of Acerra, angrily. "Pig of Kapparon, robber and pirate, yield up the boy! I, who was comrade of Henry the Emperor, will stand guardian for his son. Ho, buds of the Aloe, strike for your master's weal!"
