the birch

"What Lucy and Susan saw was a dark something coming to them from almost every direction across the hills. It looked first like a black mist creeping on the ground, then like the stormy waves of a black sea rising higher and higher as it came on, and then, at last, like what it was--woods on the move. All the trees of the world appeared to be rushing toward Aslan. But as they drew nearer they looked less like trees, and when the whole crowd, bowing and curtsying and waving thin long arms to Aslan, were all around Lucy, she saw that it was a crowd of human shapes. Pale birch-girls were tossing their heads, willow-women pushed back their hair from their brooding faces to gaze on Aslan, the queenly beeches stood still and adored him, shaggy oak-men, lean and melancholy elms, shock-headed hollies (dark themselves, but their wives all bright with berries) and gay rowans, all bowed and rose again, shouting, "Aslan, Aslan!" in their various husky or creaking or wave-like voices."
