His head was swimming, and he was far from certain even of the direction they had been going in when he had his fall. He guessed as well as he could, and crawled along for a good way, till suddenly his hand met what felt like a tiny ring of cold metal lying on the floor of the tunnel. It was a turning point in his career, but he did not know it. He put the ring in his pocket almost without thinking: certainly it did not seem of any particular use at the moment. He did not go much further, but sat down on the cold floor and gave himself up to complete miserableness.
Roads go ever ever on, Over rock and under tree, By caves where never sun has shone, By streams that never find the sea: Over snow by winter sown, And through the merry flowers of June, Over grass and over stone, And under mountains in the moon. Roads go ever ever on Under cloud and under star, Yet feet that wandering have gone Turn at last to home afar, Eyes that fire and sword have seen And horror in the halls of stone Look at last on meadows green And trees and hills they long have known.
There was a roar and a great confusion of noise. Fires lept up and licked the roof. The throbbing grew to a great tumult, and the Mountain shook. Sam ran to Frodo and picked him up and carried him out to the door. And there upon the dark threshold of the Sammath Naur, high above the plains of Mordor, such wonder and terror came on him that he stood still forgetting all else, and gazed as one turned to stone. Fire belched from its riven summit. The skies burst into thunder seared with lightning. Down like lashing whips fell a torrent of black rain. And into the heart of the storm, with a cry that pierced all other sounds, tearing the clouds asunder, the Nazgûl came, shooting like flaming bolts, as caught in the fiery ruin of hill and sky they crackled, withered, and went out.
"We will make such a chase as shall be accounted a marvel among the Three Kindreds: Elves, Dwarves and Men. Forth the Three Hunters!" Like a deer he sprang away. Through the trees he sped. On and on he led them, tireless and swift, now that his mind was at last made up. The woods about the lake they left behind. Long slopes they climbed, dark, hard-edged against the sky already red with sunset. They passed away, grey shadows in a stony land.
"I think really Bilbo preferred slipping off quietly in the end," said Gandalf, "Don't be too troubled. He'll be all right now. He left a packet for you. There it is!" Frodo took the envelope from the mantelpiece, and glanced at it, but did not open it. "You'll find his will and all the other documents in there, I think," said the wizard. "You are the master of Bag End now. And also, I fancy, you'll find a golden ring."
