[Bilbo] still wandered on, out of the little high valley, over its bulge, and down the slopes beyond; but all the while a very uncomfortable thought was growing inside him. He wondered whether he ought not, now he had a magic ring, to go back into the horrible, horrible tunnels and look for his friends. He had just made up his mind that it was his duty, and that he must turn back – and very miserable he felt about it – when he heard voices. (6.3)

Gandalf answered angrily: "I brought him, and I don't bring things that are of no use. Either you help me to look for him, or I go and leave you here to get out of the mess as best you can yourselves. If we can only find him again, you will thank me before all is over." (6.9)

So ended the adventures of the Misty Mountains. Soon Bilbo's stomach was feeling full and comfortable again, and he felt he could sleep contentedly, though really he would have liked a loaf and butter better than bits of meat toasted on sticks. He slept curled up on the hard rock more soundly than ever he had done on his feather-bed in his own little hole at home. But all night he dreamed of his own house and wandered in his sleep into all his different rooms looking for something that he could not find nor remember what it looked like. (6.97)
