Finding the Right Path . . .

There were many paths that led up into those mountains, and many passes over them. But most of the paths were cheats and deceptions and led nowhere or to bad ends; and most of the passes were infested by evil things and dreadful dangers. The dwarves and the hobbit, helped by the wise advice of Elrond and the knowledge and memory of Gandalf, took the right road to the right pass.
