About the Ents, concerning Treebeard and Quickbeam

Merry and Pippin climbed on to the bed and curled up in the soft grass and fern. It was fresh, and sweet-scented, and warm. The lights died down, and the glow of the trees faded; but outside under the arch they could see old Treebeard standing, motionless, with his arms raised above his head. The bright stars peered out of the sky, and lit the falling water as it spilled on to his fingers and head, and dripped, dripped, in hundreds of silver drops on to his feet. Listening to the tinkling of the drops the hobbits fell asleep.

He reached down two shapely arms and gave a long-fingered hand to each of the hobbits. All day they walked about, in the woods with him, singing, and laughing; for Quickbeam often laughed. He laughed if the sun came out from behind a cloud, he laughed if they come upon a stream or spring: then he stooped and splashed his feet and head with water; he laughed sometimes at some sound or whisper in the trees. Whenever he saw a rowan-tree he halted a while with his arms stretched out, and sang, and swayed as he sang.
