- "The ring felt very cold as it quietly slipped on to his groping forefinger.   The hiss was close behind him. He turned now and saw Gollum’ s eyes like small green lamps  coming up the slope. Terrified he tried to run faster, but suddenly he struck his toes on a snag in the     floor, and fell flat with his little sword under him.   In a moment Gollum was on him. But before Bilbo could do anything, recover his breath, pick  himself up, or wave his sword, Gollum passed by, taking no notice of him, cursing and whispering as  he ran.   What could it mean? Gollum could see in the dark. Bilbo could see the light of his eyes palely  shining even from behind." The Hobbit, Chapter 5 ("Riddles in the Dark"), pg. 77
