eyes of yellow and green like cats that could pierce all glooms and see through mist or fog or night ; snakes that could go everywhither and search all crannies or the deepest pits or the highest peaks , listen to every whisper that ran in the grass or echoed in the hills ; wolves there were and ravening dogs and great weasels full of the thirst of blood whose nostrils could take scent moons old through running water , or whose eyes find among shingle footsteps that had passed a lifetime since ; owls came and falcons whose keen glance might descry by day or night the fluttering of small birds in all the woods of the world , and the movement of every mouse or vole or rat that crept or dwelt throughout the earth .
