But at this moment the grandfather's stentorian voice was heard. "Why is the army not marching forward? Is it the field-marshal who is missing or some of the troops?" Whereupon Peter turned and went off, swinging his stick round so that it whistled through the air, and the goats, who understood the signal, started at full trot for their mountain pasture, Peter following in their wake. Since Heidi had come back to her grandfather she had learned to do many things about the house. She put her bed in order every morning, patting and stroking it till she had got it perfectly smooth and flat. Then she went about the room downstairs, put each chair back in its place, and if she found anything lying about she put it in the cupboard. After that she fetched a duster, climbed on a chair, and rubbed the table till it shone again. When the grandfather came in later he would look round well pleased and say to himself, "We look like Sunday every day now; Heidi did not go abroad for nothing." After Peter had departed and she and her grandfather had breakfasted, Heidi began her daily work as usual, but she did not get on with it very fast. It was so lovely out of doors today, and every minute something happened to interrupt her in her work. Now it was a bright beam of sun shining cheerfully through the open window, and seeming to say, "Come out, Heidi, come out!" Heidi felt she could not stay indoors, and she ran out in answer to the call. The sunlight lay sparkling on everything around the hut and on all the mountains and far away along the valley, and the grass slope looked so golden and inviting that she was obliged to sit down for a few minutes and look about her. Then she suddenly remembered that her stool was left standing in the middle of the floor and that the table had not been rubbed, and she jumped up and ran inside again. But it was not long before the fir trees began their old song; Heidi felt it in all her limbs, and again the desire to run outside was irresistible, and she was off to play and leap to the tune of the waving branches. The grandfather, who was busy in his work-shed, stepped out from time to time smiling to watch her at her gambols. He had just gone back to his work on one of these occasions when Heidi called out, "Grandfather! Grandfather! Come, come!" He stepped quickly out, almost afraid something had happened to the child, but he saw her running towards where the mountain path descended, crying, "They are coming! they are coming! and the doctor is in front of them!" Heidi rushed forward to welcome her old friend, who held out his hands in greeting to her. When she came up to him she clung to his outstretched arm, and exclaimed in the joy of her heart, "Good-morning, doctor, and thank you ever so many times." "God bless you, child! what have you got to thank me for?" asked the doctor, smiling. "For being at home again with grandfather," the child explained.
