The stillness was so profound that he heard a little animal twittering somewhere near by under the snow. It made a small frightened cheep like a field mouse, and he wondered languidly if it were hurt. Then he understood that it must be in pain: pain so excruciating that he seemed, mysteriously, to feel it shooting through his own body. He tried in vain to roll over in the direction of the sound, and stretched his left arm out across the snow. And now it was as though he felt rather than heard the twittering; it seemed to be under his palm, which rested on something soft and springy. The thought of the animal's suffering was intolerable to him and he struggled to raise himself, and could not because a rock, or some huge mass, seemed to be lying on him. But he continued to finger about cautiously with his left hand, thinking he might get hold of the little creature and help it; and all at once he knew that the soft thing he had touched was Mattie's hair and that his hand was on her face.
