O Queen beyond the Western Seas
O light to us that wander here
Amid the world of woven trees!" Book 1, Chapter 3, pg. 108
These elves are high elves and they speak to Frodo. They laugh and poke fun at the other hobbits. The hobbits ask about the black rider and the elves tell them one has passed. They tell the hobbits to follow them into the forest. It gets thicker but then opens suddenly. They sit in a beautiful clearing. The elves bring them into a hall where they are fed. Pippin falls asleep. The elves recognize Frodo from his outings with Bilbo. They love him. He asks them about Bilbo and their leader says little. They don't know where he went. He asks Frodo about his journey and tells hin that it is safe to tell him. The Elves don't want to speak about the black riders. They tell him to continue on and consult Gandalf when they find him. Frodo is worried that Gandalf is late. He cannot decide whether he should wait for the wizard or go on without him. The leader of the elves tells him to move on and avoid the black riders at all costs. He names him an Elf -friend and Frodo falls asleep.
