"I'll ride you if it breaks--my neck!" panted Bo, passionately, shaking her gloved fist at the gray pony.
Dale stood near with a broad smile on his face. Helen was within earshot, watching from the edge of the park, and she felt so fascinated and frightened that she could not call out for Bo to stop. The little gray mustang was a beauty, clean-limbed and racy, with long black mane and tail, and a fine, spirited head. There was a blanket strapped on his back, but no saddle. Bo held the short halter that had been fastened in a hackamore knot round his nose. She wore no coat; her blouse was covered with grass and seeds, and it was open at the neck; her hair hung loose and disheveled; one side of her face bore a stain of grass and dirt and a suspicion of blood; the other was red and white; her eyes blazed; beads of sweat stood out on her brow and wet places shone on her cheeks. As she began to strain on the halter, pulling herself closer to the fiery pony, the outline of her slender shape stood out lithe and strong.
Bo had been defeated in her cherished and determined ambition to ride Dale's mustang, and she was furious. The mustang did not appear to be vicious or mean. But he was spirited, tricky, mischievous, and he had thrown her six times. The scene of Bo's defeat was at the edge of the park, where thick moss and grass afforded soft places for her to fall. It also afforded poor foothold for the gray mustang, obviously placing him at a disadvantage. Dale did not bridle him, because he had not been broken to a bridle; and though it was harder for Bo to try to ride him bareback, there was less risk of her being hurt. Bo had begun in all eagerness and enthusiasm, loving and petting the mustang, which she named "Pony." She had evidently anticipated an adventure, but her smiling, resolute face had denoted confidence. Pony had stood fairly well to be mounted, and then had pitched and tossed until Bo had slid off or been upset or thrown. After each fall Bo bounced up with less of a smile, and more of spirit, until now the Western passion to master a horse had suddenly leaped to life within her. It was no longer fun, no more a daring circus trick to scare Helen and rouse Dale's admiration. The issue now lay between Bo and the mustang.
Pony reared, snorting, tossing his head, and pawing with front feet.
