"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.
