"Let me see that bell," puffed Peter, reaching across the tray. It was not very light in the cavern, but even so he could read the inscription on the shining silver surface. "The Red Djinn's dinner bell," said the carved letters mysteriously. "A magic dinner bell," exclaimed Peter delightedly. "This certainly makes up for the bird seed. And did you see that boy dissolve into nothing right before our eyes?" Jack nodded. "Better eat that dinner before it does the same thing," he advised calmly. As this seemed not at all improbable, Peter made short work of the roast duck, mashed potatoes, hot rolls and apple sauce. He had just finished the last roll, when tray, dishes and silverware vanished suddenly. "Shall I ring the bell again?" inquired Jack, as Peter stared dazedly at the spot where the tray had been. Although Jack was not constructed for eating, he had thoroughly enjoyed watching Peter. "No," decided the little boy with a satisfied nod, "I've had enough, and it was good. But I wonder how that Christmas tree got hold of the Red Djinn's dinner bell?" "Stole it probably," answered Jack, rubbing the bell on his sleeve. "Maybe the old Djinn didn't run fast enough. Anyway it's a regular Christmas present for you, Peter. Whenever you're hungry we'll just ring it." With a pleased chuckle, Jack slipped the bell back into his pocket. "It certainly will be useful," sighed Peter, patting his stomach with a contented little sigh. Now that his hunger was satisfied, he felt quite cheerful and adventurous again. "Let's see where this passageway leads," he added, peering round the dark corner at the end of the little corridor. "Why don't you throw that old sack away?" inquired Jack Pumpkinhead, as they walked slowly along the strange hallway. "What good is it?" "I don't know," answered Peter, swinging the pirate's sack carelessly to and fro. "I had it when I landed here and it might come in handy to carry things in." "What kind of things?" asked Jack stupidly. Peter did not bother to answer for they had come suddenly upon a great scowling goblin-head lantern. Under the lantern hung a flashing red sign. "T--remble!"--directed the sign in big red letters. "I don't see why we should tremble," said Peter, squinting defiantly up at the goblin lantern. At Peter's words the lantern went out, and whistling through the dark windy corridor came such a succession of wails, sighs and horrid screeches that Peter's heart stood still. "Are you trembling?" quavered Jack, as the hair raising noise died away. "Not exactly," stuttered Peter, leaning against the wall to steady himself. As the lantern flashed on again, he peered anxiously all around. But there was no one in sight, so putting back his shoulders and taking a deep breath Peter marched bravely forward. "There's nothing to be frightened about," he called reassuringly over his shoulder.
