"He is mocking at the people who live down below in the villages, because they all go huddling and gossiping together, and encourage one another in evil talking and deeds. He calls out, 'If you would separate and each go your own way and come up here and live on a height as I do, it would be better for you!' " There was almost a wildness in the old man's voice as he spoke, so that Heidi seemed to hear the croaking of the bird again even more distinctly.

"Why haven't the mountains any names?" Heidi went on.

"They have names," answered her grandfather, "and if you can describe one of them to me that I know I will tell you what it is called."

Heidi then described to him the rocky mountain with the two high peaks so exactly that the grandfather was delighted. "Just so, I know it," and he told her its name. "Did you see any other?"

Then Heidi told him of the mountain with the great snow-field, and how it had been on fire, and had, turned rosy-red and then all of a sudden had grown quite pale again and all the color had disappeared.

"I know that one too," he said, giving her its name. "So you enjoyed being out with the goats?"

Then Heidi went on to give him an account of the whole day, and of how delightful it had all been, and particularly described the fire that had burst out everywhere in the evening. And then nothing would do but her grandfather must tell how it came, for Peter knew nothing about it.

The grandfather explained to her that it was the sun that did it. "When he says good-night to the mountains he throws his most beautiful colors over them, so that they may not forget him before he comes again the next day."
