Rejoice always

All that 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 came 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.
