Good Hobbit Morning chapter 12 "Inside information"

"Inside the mountain, he put on the ring, rendering him invisible, and crept down the tunnel, deeper into the mountain. He wished he was back home in The Shire. As he descended, he felt it getting hotter until he could hear a deep rumbling: the snoring of some giant creature. Summoning every ounce of his bravery, he continued until came into the hall of the mountain. There he saw the red-golden dragon Smaug, slumbering on uncounted gems and jewels and gold."
