of the time until recess in a state of helpless wonderment. Like the average boy under such circumstances, he racked his brains trying to recollect what he could have done that might have offended Callie. But there seemed to be no solution to the mystery.
Perhaps she had heard of how he had been fooled by the stranger yesterday. Perhaps she felt contempt for him because he had been so easily outwitted. This was one of his wild surmises, but he rejected it because it was not like Callie to be angry about anything unless there was good reason for her displeasure. At last he gave it up and tried to dismiss the matter from his mind, but several times during the morning he cast covert glances in her direction.
But Callie was plainly worried and downcast. She seldom raised her eyes from her books, she answered the teacher's questions in a most abstracted manner, and altogether it appeared that there was something on her mind beyond schoolwork.
When recess came she walked slowly out of the room, not mingling with the other girls. Frank saw her go outside toward the campus, where she sat down on the grass by herself, watching an impromptu basketball game and declining all requests to join in the fun.
He went over to her and flung himself down on the grass beside the girl.
