Ulyth, with the rest of V B, was obliged to march off to her form-room. The inquiry had delayed the morning's work, and Miss Harding began to give out books without a moment's further waste of time. Ulyth sat staring at the problem set her, without in the least taking in its details. She could not apply her mind to the calculation of cubic contents while Rona was crying her heart out upstairs. What did it, what could it, all mean? Had her room-mate only been intending to play a practical joke on Stephanie? If so, why had she not at once admitted the fact? Nobody would have thought much the worse of her for it, as such jokes had been rather the rage of late among the juniors. It seemed so unlike Rona to conceal it; lack of candour had not been her fault hitherto. She was generally proud of the silly tricks she was fond of playing, and anxious to boast about them. She could not have been deterred by dread of the Principals' displeasure. Only yesterday she had marched into the study, to report herself for talking, with a sangfroid that was the admiration of her form; and had come out again smiling, with the comment that both the Rainbow and Teddie were "as decent as anything if one owned up straight". No, there must be another and a much graver explanation. A chain of circumstances flashed through Ulyth's mind, each unfortunate link fitting only too well. The evidence seemed almost overwhelming. Rona had been present at the meeting by the stream when Tootie incited the juniors to some secret act of rebellion against the school rules. What this act was the occurrence in the garden had plainly shown. That Rona had been implicated seemed a matter of certainty. Her brooch had been in the possession of the cake-vendor, and she had chocolates in her bedroom, the acquisition of which she had refused to explain. Did she intend to keep the pendant and exchange it for confectionery? Her pocket-money, as Ulyth knew, was exhausted, and she had hardly any of the trinkets that most girls wear. "Ulyth Stanton, you are not attending to your work. Give me your answer to Problem 46." Ulyth started guiltily. Her page was still a blank, and she had no answer to produce. She murmured a lame excuse, and Miss Harding glared at her witheringly. Thrusting her preoccupation resolutely aside, she made an effort to concentrate her thoughts upon the subject in hand. The morning passed slowly on. To Ulyth each successive class seemed interminable. At recreation, the girls, in small clumps, discussed the one topic of the hour. "I'm not surprised. I'd think anything of Rona Mitchell," said Stephanie. "What else could you expect of a girl from the backwoods?" "But she was so much improved," urged Addie, who had rather a weakness for the Cuckoo. "Only a veneer. She relapsed directly she got the chance, you see." "But why should she take your pendant?"
