Page "Gandalf" Paragraph 29

Returning to the Shire, in, Gandalf confirmed his suspicions by throwing the Ring into Frodo's hearth fire and reading the writing that appeared on the Ring's surface.

He told Frodo the full history of the Ring, and urged him to take the Ring to Rivendell ; for he would be in grave danger if he stayed in the Shire.

Gandalf said he would attempt to return for Frodo's fiftieth birthday party, in order to accompany him on the road thereafter ; and that meanwhile Frodo should arrange to leave quietly, as the servants of Sauron would be searching for him.
