It is no use arguing. I have, as I told you, some pressing business away south; and I am already late through bothering with you people. We may meet again before all is over, and then again of course we may not. That depends on your luck and on your courage and sense; and I am sending Mr. Baggins with you. I have told you before that he has more about him than you guess, and you will find that out before long. So cheer up Bilbo and don't look so glum. Cheer up Thorin and Company! This is your expedition after all. (7.36)

There is [a way around Mirkwood], if you care to go two hundred miles or so out of your way north, and twice that south. But you wouldn't get a safe path even then. There are no safe paths in this part of the world. Remember you are over the Edge of the Wild now, and in for all sorts of fun wherever you go. Before you could get round Mirkwood in the North you would be right among the slopes of the Grey Mountains, and they are simply stiff with goblins, hobgoblins, and orcs of the worst description. Before you could get round it in the South, you would get into the land of the Necromancer, and even you, Bilbo, won't need me to tell you tales of that black sorcerer. I don't advise you to go anywhere near the places overlooked by his dark tower! Stick to the forest-track, keep your spirits up, hope for the best, and with a tremendous slice of luck you may come out one day and see the Long Marshes lying below you and beyond them, high in the East, the Lonely Mountain where dear old Smaug lives, though I hope he is not expecting you.
