"But you must; I cannot do it alone, and you must come here and help me; make haste and come down," she called again in an urgent voice. "I shall do nothing of the kind," was the answer. Heidi ran some way up the slope towards him, and then pausing called again, her eyes ablaze with anger, "If you don't come at once, Peter, I will do something to you that you won't like; I mean what I say." Peter felt an inward throe at these words, and a great fear seized him. He had done something wicked which he wanted no one to know about, and so far he had thought himself safe. But now Heidi spoke exactly as if she knew everything, and whatever she did know she would tell her grandfather, and there was no one he feared so much as this latter person. Supposing he were to suspect what had happened about the chair! Peter's anguish of mind grew more acute. He stood up and went down to where Heidi was awaiting him. "I am coming, and you won't do what you said." Peter appeared now so submissive with fear that Heidi felt quite sorry for him and answered assuringly, "No, no, of course not; come along with me, there is nothing to be afraid of in what I want you to do." As soon as they got to Clara, Heidi gave her orders: Peter was to take hold of her under the arms on one side and she on the other, and together they were to lift her up. This first movement was successfully carried through, but then came the difficulty. As Clara could not even stand, how were they to support her and get her along? Heidi was too small for her arm to serve Clara to lean upon. "You must put one arm well round my neck--so, and put the other through Peter's and lean firmly upon it, then we shall be able to carry you." Peter, however, had never given his arm to any one in his life. Clara put hers in his, but he kept his own hanging down straight beside him like a stick. "That's not the way, Peter," said Heidi in an authoritative voice. "You must put your arm out in the shape of a ring, and Clara must put hers through it and lean her weight upon you, and whatever you do, don't let your arm give way; like that I am sure we shall be able to manage." Peter did as he was told, but still they did not get on very well. Clara was not such a light weight, and the team did not match very well in size; it was up one side and down the other, so that the supports were rather wabbly. Clara tried to use her own feet a little, but each time drew them quickly back. "Put your foot down firmly once," suggested Heidi, "I am sure it will hurt you less after that." "Do you think so," said Clara hesitatingly, but she followed Heidi's advice and ventured one firm step on the ground and then another; she called out a little as she did it; then she lifted her foot again and went on, "Oh, that was less painful already," she exclaimed joyfully.
