"Oh, come on," pleaded Sahwah; "it's more fun to go down a steep hill. You go so much faster. It lands you in a snowbank at the bottom, but it's perfectly safe." None of the boys and girls appeared anxious to go. Sahwah jumped up and down with impatience. "Oh, you slowpokes!" she exclaimed, rather crossly. Then she turned to Dick Albright. "Dick," she said, "will you come with me even if the others won't?" Dick shook his head. "It's dangerous," he answered. "You're afraid," said Sahwah tauntingly. "I'm not," said Dick hotly. "You are too," said Sahwah. "All right if you're afraid, but I know some one who wouldn't be." Now Sahwah had no one definite in mind when she said this last, it was simply an effort to make Dick feel small, but Dick immediately took it as a reference to the unknown Ned Roberts who had sent her the valentine, and his jealousy got the better of his discretion. "All right," he said, firmly determined to measure up to this pattern of dauntlessness, "come on if you want to. I'll go with you." The two climbed up the steep hill, dragging the bob after them. When Sahwah was sitting behind the steering wheel, poised at the top and ready to make the swift descent, she shuddered at the sight of the sharp incline. It looked so much worse from the top than from the bottom. She would have drawn back and given it up, but Sahwah had a stubborn pride that shrank from saying she was afraid to do anything she had undertaken. "Shove off!" she commanded, gritting her chattering teeth together. The bob shot downward like a cannon ball. In spite of her terror Sahwah enjoyed the sensation. She held firmly on to the steering wheel and made for the great bank of snow which had been thrown up by the men cleaning the foot walks. At that moment an automobile turned into the lake drive, and its blinding lights shone full into Sahwah's eyes. Dazzled, she turned her head away, at the same time jerking the steering wheel to the right. The bob swerved sharply to one side and crashed into a tree. The force of the impact threw Dick clear of the sled and he rolled head over heels down the hill, landing in the snow at the bottom badly shaken, but otherwise unhurt. Sahwah lay motionless in the snow beside the wreck of the bob. CHAPTER XII. DR. HOFFMAN. The girls and boys crowded around her with frightened faces. "Is she killed?" they asked each other in terrified tones. "It's all my fault," said Dick Albright, nearly beside himself; "I should have known better than to let her go. She didn't think of the danger, but I did, and I should have prevented her. Was there ever such a fool as I?" Gladys and Migwan were kneeling beside Sahwah and opening her coat. "She is not dead," said Gladys, feeling her pulse. "We must get her home. She is possibly only stunned." Sahwah moved slightly and groaned, but she did not open her eyes. A passing automobile was hailed and she was carried to it as carefully as possible and taken home.
