Heidi got down and skipped across the large room after her grandfather, who opened a door at the farther end leading into a smaller one which was to be his bed-room. Then came another door. Heidi pushed it open and stood amazed, for here was an immense room like a kitchen, larger than anything of the kind that Heidi had seen before. There was still plenty of work for the grandfather before this room could be finished, for there were holes and cracks in the walls through which the wind whistled, and yet he had already nailed up so many new planks that it looked as if a lot of small cupboards had been set up round the room. He had, however, made the large, old door safe with many screws and nails, as a protection against the outside air, and this was very necessary, for just beyond was a mass of ruined building overgrown with tall weeds, which made a dwelling-place for innumerable beetles and lizards. Heidi was very delighted with her new home, and by the morning after their arrival she knew every nook and corner so thoroughly that she could take Peter over it and show him all that was to be seen; indeed she would not let him go till he had examined every single wonderful thing contained in it. Heidi slept soundly in her corner by the stove; but every morning when she first awoke she still thought she was on the mountain, and that she must run outside at once to see if the fir trees were so quiet because their branches were weighed down with the thick snow. She had to look about her for some minutes before she felt quite sure where she was, and a certain sensation of trouble and oppression would come over her as she grew aware that she was not at home in the hut. But then she would hear her grandfather's voice outside, attending to the goats, and these would give one or two loud bleats, as if calling to her to make haste and go to them, and then Heidi was happy again, for she knew she was still at home, and she would jump gladly out of bed and run out to the animals as quickly as she could. On the fourth morning, as soon as she saw her grandfather, she said, "I must go up to see grandmother today; she ought not to be alone so long." But the grandfather would not agree to this. "Neither today nor tomorrow can you go," he said, "the mountain is covered fathom-deep in snow, and the snow is still falling; the sturdy Peter can hardly get along. A little creature like you would soon be smothered by it, and we should not be able to find you again. Wait a bit till it freezes, then you will be able to walk over the hard snow."
