“And suddenly first one and then another began to sing as they played, deep-throated singing of the dwarves in the deep places of their ancient homes; and this is like a fragment of their song, if it can be like their song without their music. [...] As they sang the hobbit felt the love of beautiful things made by hands and by cunning and by magic moving through him, a fierce and a jealous love, the desire of the hearts of dwarves. Then something Tookish woke up inside him, and he wished to go and see the great mountains, and hear the pine-trees and the waterfalls, and explore the caves, and wear a sword instead of a walking-stick. He looked out of the window. The stars were out in a dark sky above the trees. He thought of the jewels of the dwarves shining in dark caverns. Suddenly in the wood beyond The Water a flame leapt up—probably somebody lighting a wood-fire—and he thought of plundering dragons settling on his quiet Hill and kindling it all to flames. He shuddered; and very quickly he was plain Mr. Baggins of Bag-End, Under-Hill, again.
He got up trembling. He had less than half a mind to fetch the lamp, and more than half a mind to pretend to, and go and hide behind the beer-barrels in the cellar, and not come out again until all the dwarves had gone away.”
