His remarks, it is needless to say, did not have reference to his beloved teacher. It was in the atmosphere everywhere that something was bound to happen if this strain kept up. Margaret knew it and felt utterly inadequate to meet it. Rosa knew it and was awaiting her opportunity. Bud knew it and could only stand and watch where the blow was to strike first and be ready to ward it off. In these days he wished fervently for Gardley's return. He did not know just what Gardley could do about "that little fool," as he called Rosa, but it would be a relief to be able to tell some one all about it. If he only dared leave he would go over and tell Jasper Kemp about it, just to share his burden with somebody. But as it was he must stick to the job for the present and bear his great responsibility, and so the days hastened by to the last Sunday before Commencement, which was to be on Monday. CHAPTER XXVII Margaret had spent Saturday in rehearsals, so that there had been no rest for her. Sunday morning she slept late, and awoke from a troubled dream, unrested. She almost meditated whether she would not ask some one to read a sermon at the afternoon service and let her go on sleeping. Then a memory of the lonely old woman at the camp, and the men, who came so regularly to the service, roused her to effort once more, and she arose and tried to prepare a little something for them. She came into the school-house at the hour, looking fagged, with dark circles under her eyes; and the loving eyes of Mom Wallis already in her front seat watched her keenly. "It's time for _him_ to come back," she said, in her heart. "She's gettin' peeked! I wisht he'd come!" Margaret had hoped that Rosa would not come. The girl was not always there, but of late she had been quite regular, coming in late with her father just a little after the story had begun, and attracting attention by her smiles and bows and giggling whispers, which sometimes were so audible as to create quite a diversion from the speaker. But Rosa came in early to-day and took a seat directly in front of Margaret, in about the middle of the house, fixing her eyes on her teacher with a kind of settled intention that made Margaret shrink as if from a danger she was not able to meet. There was something bright and hard and daring in Rosa's eyes as she stared unwinkingly, as if she had come to search out a weak spot for her evil purposes, and Margaret was so tired she wanted to lay her head down on her desk and cry. She drew some comfort from the reflection that if she should do so childish a thing she would be at once surrounded by a strong battalion of friends from the camp, who would shield her with their lives if necessary.
