The merchant did not have long to wait. All unconscious of the part he was to play in Matiah's dark schemes, a young Kitchen Boy came whistling his way toward a great golden bin of potatoes. The bin was just beyond the trapdoor, and lowering it to a mere crack, Matiah let the boy pass. Then, as he leaned down to fill his basket, the wily merchant flung up the trapdoor, fell upon the boy and carried him kicking and screaming down the stairs. Here, with threats, promises and innumerable shakings, he finally reduced the poor lad to a state of frightened submission. With the sparkling necklaces round his neck, he touched one and then another of the emeralds as Matiah wished and counted and counted and wished. After each unsuccessful trial the merchant would rage and stamp and shake his fists, till the boy was quite convinced he was in the presence and power of a mad man, and frantically waited for someone to overhear Matiah's ravings and come down to rescue him. But nobody did! While the unfortunate Kitchen Boy was spending a miserable morning in the underground chamber, Skamperoo and Chalk were going through the motions of enjoying themselves above stairs, but without any real zest or pleasure. Only half-heartedly Skamperoo laughed at the jokes of the Scarecrow, and Chalk, for all his bright interest in the long recital of Kabumpo's adventures, was really in a fidget of uneasiness, trying to keep an eye on all the doors and windows in the Throne Room at once. Something was going to happen. The white horse felt it in every bone. And just as the soft musical gong sounded the call for luncheon, his worst fears were realized. Suddenly, without reason or warning, the castle was plunged into total darkness. Thumps, bumps, hysterical shouts and screams followed closely on the heels of this disconcerting event. Chalk, who had been standing back of Skamperoo, immediately leaned forward and grasped his impetuous little Master by the seat of his Royal Breeches. "Be still!" commanded the white horse through his teeth and the white leather of Skamperoo's riding pants, and he held on for dear life as the Emperor, like all the rest of the court and guests tried to rush in every direction. "He's done it! He's done it, and everything, is ruined," wailed Skamperoo, struggling in vain to pull away from Chalk. "Matiah has discovered the secret of the necklaces and now we are ruined--do you hear--ruined!" "I hear," hissed Chalk, giving Skamperoo a little shake, "and so will everyone else unless you shut your mouth. Be quiet, I tell you, do nothing till the right moment, unless you want to dash out your brains against a pillar in the dark." Too frightened to argue or struggle further, Skamperoo at last subsided. All about courtiers, servants, and guests were screaming and bumping into each other or the furniture, and when a stern hand suddenly seized his bridle, Chalk trembled violently in spite of himself.
