'That morning they lit a fire in a deep hollow shrouded by great bushes of holly, and their supper-breakfast was merrier than it had been since they set out. They did not hurry to bed afterwards, for they expected to have all the night to sleep in, and they did not mean to go on again until the evening of the next day. Only Aragorn was silent and restless. After a while he left the Company and wandered on to the ridge; there he stood in the shadow of a tree, looking out southwards and westwards, with his head posed as if he was listening. Then he returned to the brink of the dell, and looked down at the others laughing and talking.'
