Returning to the Shire, Gandalf confirms his suspicions by throwing the Ring into Frodo's hearth-fire and reading the writing that appears on the Ring's surface. He tells Frodo the history of the Ring, and urges him to take it to Rivendell, for he will be in grave danger if he stays in the Shire. Gandalf says he will attempt to return for Frodo's 50th birthday party, to accompany him on the road; and that meanwhile Frodo should arrange to leave quietly, as the servants of Sauron will be searching for him.
