The Naiads and Dryads were scattering in every direction. Lucy was running towards him as fast as her short legs would carry her and her face was as white as paper. Then he saw Susan make a dash for a tree, and swing herself up, followed by a huge grey beast. At first Peter thought it was a bear. Then he saw that it looked like an Alsatian, though it was far too big to be a dog. Then he realized that it was a wolf.a wolf standing on its hind legs, with its front paws against the tree.trunk, snapping and snarling. All the hair on its back stood up on end. Susan had not been able to get higher than the second big branch. One of her legs hung down so that her foot was only an inch or two above the snapping teeth. Peter wondered why she did not get higher or at least take a better grip; then he realized that she was just going to faint and that if she fainted she would fall off.
