"Remember it's your own fault, missy," said Uncle Ben; "this aint the 'orse I'd give you. I don't want any harm to come to you; but if you insist on that little chap, that aint a patch on you, riding Greased Lightning, why, there aint nothing for it but for you to ride Pole Star." "You don't 'uppose I's fwightened of Pole Star? Why, he's a weal beauty," said Diana. "He's the----" The man arrested the words on his lips. Diana had thrown down her whip and rushed across the stage. With just the same fearless confidence as, half an hour before, she had gone up to Greased Lightning--she now approached Pole Star. "You's pwetty, you's a darlin'," she said. She held out her tiny brown hand. "Give me a bit of sugar, somebody," she demanded. A girl who stood near ran away to fetch a lump. The child offered it to the horse. He looked at her, pawed the ground restlessly, and then, stooping, licked the sugar off her hand as tenderly as if he were a kitten. "Well, I never!" said Uncle Ben, breathing a great sigh of relief. "It's a beauty horse," repeated Diana; "I like it better nor G'eased Lightning. Pole Star, I's going to wide you; you's a dear, good horse." She stroked the creature's nose--the fierce eyes grew gentle--a moment later the child was mounted on its back. "Now, gee up, gee up!" called Diana. "P'ease, Uncle Ben, don't cwack your whip; I can manage Pole Star." She pulled at the reins, and the creature began, at first gently and then more rapidly, to run round and round the stage. After all, notwithstanding her bravery, it was an ordeal, for Pole Star could run double as fast as Greased Lightning. Soon, from running he seemed to take to flying, and little Diana gasped and lost her breath; but she sat firm as a statue, and never touched a hair of the creature's mane. "Now, Pole Star," she called out, when the horse had stopped for want of breath; "I's going to stand on you, and you must be vedy good." She patted the animal on its head; then she scrambled to her feet, and, holding the reins taut, stood firm as an arrow, while the creature once more flew round the stage. When her ride was over she had won the applause of the whole house. After this Diana and Orion were taken away to rest until the evening. They were given the best food and a great deal of petting from Aunt Sarah. As to Diana, she was in excellent spirits. "Oh, please, Di; nothing will make you stop, nothing will make you break your word?" said little Orion once to her. "What I pwomise I do," replied Diana, with dignity. And so the hours flew by, and at last the time arrived when the children were to appear before the footlights. The huge circus tent was packed to the highest gallery. There was, in short, not standing room in the audience part of the house. Uncle Ben, in the highest spirits, was darting here and there behind the wings, giving directions, gesticulating, ordering, rearranging. Little Diana flew up to him and took his hand.
