So now, when she saw some one coming, she felt the necessity of bringing her telltale face to order and getting ready to answer whoever she was to meet. As she drew nearer she became suddenly aware that it was Rosa Rogers coming with her arms full of bundles and more piled up in front of her on her pony. Margaret knew at once that Rosa must have seen Forsythe go by her house, and had returned promptly to the school-house on some pretext or other. It would not do to let her go there alone with the young man; she must go back and stay with them. She could not be sure that if she sent Rosa home with orders to rest she would be obeyed. Doubtless the girl would take another way around and return to the school again. There was nothing for it but to go back and stay as long as Rosa did.
Margaret stooped and, hastily plucking a great armful of sage-brush, turned around and retraced her steps, her heart like lead, her feet suddenly grown heavy. How could she go back and hear them laugh and chatter, answer their many silly, unnecessary questions, and stand it all? How could she, with that great weight at her heart?
She went back with a wonderful self-control. Forsythe's face lighted, and his reluctant hand grew suddenly eager as he worked. Rosa came presently, and others, and the laughing chatter went on quite as Margaret had known it would. And she--so great is the power of human will under pressure--went calmly about and directed here and there; planned and executed; put little, dainty, wholly unnecessary touches to the stage; and never let any one know that her heart was being crushed with the weight of a great, awful fear, and yet steadily upborne by the rising of a great, deep trust. As she worked and smiled and ordered, she was praying: "Oh, God, don't let it be true! Keep him! Save him! Bring him! Make him true! I know he is true! Oh, God, bring him safely soon!"
Meantime there was nothing she could do. She could not send Forsythe after him. She could not speak of the matter to one of those present, and Bud--where was Bud? It was the first time since she came to Arizona that Bud had failed her. She might not leave the school-house, with Forsythe and Rosa there, to go and find him, and she might not do anything else. There was nothing to do but work on feverishly and pray as she had never prayed before.
By and by one of the smaller boys came, and she sent him back to the Tanners' to find Bud, but he returned with the message that Bud had not been home since morning; and so the last hours before the evening, that would otherwise have been so brief for all there was to be done, dragged their weary length away and Margaret worked on.
