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. “Pull him down!” yelled Dale. Bo did not have much weight, but she had strength, an she hauled with all her might, finally bringing him down. “Now hold hard an' take up rope an' get in to him,” called Dale. “Good! You're sure not afraid of him. He sees that. Now hold him, talk to him, tell him you're goin' to ride him. Pet him a little. An' when he quits shakin', grab his mane an' jump up an' slide a leg over him. Then hook your feet under him, hard as you can, an' stick on.” If Helen had not been so frightened for Bo she would have been able to enjoy her other sensations. Creeping, cold thrills chased over her as Bo, supple and quick, slid an arm and a leg over Pony and straightened up on him with a defiant cry. Pony jerked his head down, brought his feet together in one jump, and began to bounce. Bo got the swing of him this time and stayed on. “You're ridin' him,” yelled Dale. “Now squeeze hard with your knees. Crack him over the head with your rope.... That's the way. Hang on now an' you'll have him beat.” The mustang pitched all over the space adjacent to Dale and Helen, tearing up the moss and grass. Several times he tossed Bo high, but she slid back to grip him again with her legs, and he could not throw her. Suddenly he raised his head and bolted. Dale answered Bo's triumphant cry. But Pony had not run fifty feet before he tripped and fell, throwing Bo far over his head. As luck would have it--good luck, Dale afterward said--she landed in a boggy place and the force of her momentum was such that she slid several yards, face down, in wet moss and black ooze.
