"That is a beautiful faith, child, and be sure you hold it fast," replied the doctor. Then he sat on a while in silence, looking at the great overshadowing mountains and the green, sunlit valley below before he spoke again,--

"Can you understand, Heidi, that a man may sit here with such a shadow over his eyes that he cannot feel and enjoy the beauty around him, while the heart grows doubly sad knowing how beautiful it could be? Can you understand that?"

A pain shot through the child's young happy heart. The shadow over the eyes brought to her remembrance the grandmother, who would never again be able to see the sunlight and the beauty up here. This was Heidi's great sorrow, which re-awoke each time she thought about the darkness. She did not speak for a few minutes, for her happiness was interrupted by this sudden pang. Then in a grave voice she said,--

"Yes, I can understand it. And I know this, that then one must say one of grandmother's hymns, which bring the light back a little, and often make it so bright for her that she is quite happy again. Grandmother herself told me this."
