"Hadn't I better go over to the tent with you?" asked the patient. To have an arm set with two strange girls looking on was evidently not to his taste. "Too far for you to walk if you feel as shaky as you look," said Doctor Abbott, his keen eyes taking in young Knight's pale face and twitching lips. "And I may need assistance." He sprang lightly into the seat beside the patient and made a rapid examination. The girls resolutely kept their eyes away, but they could hear the boy's quick breathing. He made no other sound. "A sprain, my boy," was the verdict which the girls heard with vast relief. "Only a sprain?" asked Knight in an injured tone. "Then what makes it hurt so like the mischief?" "A sprain hurts worse than a fracture, sometimes, but it is less serious and will heal quicker," said the doctor. "I've just the right thing here and will fix you up in no time." The next five minutes were bad ones for the sufferer; Sarah and Blue Bonnet knew it, though they still stared off over the meadow and tried to chat unconcernedly, while the hurried breathing of the boy continued. "There you are!" The girls turned to see the young man viewing his work and the neat bandage with approval, while Knight, with his lips still trembling, looked up at him with forced cheerfulness. "You'll have to keep it still for a few days,--wish we had some sort of a sling." Abbott knit his brow. Knight touched the bandanna about his neck. "How about this?" Abbott tried it but found it too short. Blue Bonnet had one of her sudden inspirations. Diving down underneath the seat she fished up one of the many packages. Under the interested eyes of the others she opened it and then held up something bright and silky. "Your red sash!" gasped Sarah. "Will it do?" Blue Bonnet asked the doctor anxiously. "Just the thing!" he exclaimed; and in a minute had slung his patient's arm in the scarlet folds of the sash. "I say," Knight protested, "I hate like everything to take this from you, Miss Ashe." Blue Bonnet gave him a bright smile. "I'm very glad to have it prove so useful. Sarah called me frivolous when I bought it." The boy looked uncomfortable but was forced to submit, vowing inwardly that he would buy her the "fanciest article in the sash line" that Chicago could boast, to make up for the loss of her finery. "Now, my friend," said the young surgeon, as he gathered up his instrument case in a professional manner, "I must see that wrist in the morning. Where are you staying?" The youth colored; it was evident that he had expected an invitation to stay with his friend. Blue Bonnet spoke up at once: "You must come with us to the ranch. Uncle would never forgive me if I let you stay anywhere else." "Sorry I can't ask you to stay with me," Abbott said, observing the boy's confusion. "But I've only a cot built for one, you know. You'll be a heap more comfortable at the Blue Bonnet ranch than in my quarters. I'll ride over in the morning and take a look at you."
