The _thlot_ led them off into the darkness. At last a dim glow of light showed up ahead. Andy pushed ahead of the honey-bear, stepped through a narrow opening, got a glimpse of the rim of Jupiter, red and angry, immovable on the horizon. He was suddenly very tired. He sat down heavily, stared at the forbidding planet. Forbidding it was, but it looked mighty good to him at that moment. The soft purring of the _thlot_ made him turn his head. The girl had sunk to the ground. She was scratching him and he was purring. Andy looked at him reprovingly. "I know it's poppycock," said Oscar, "but I like it. You ought to have her scratch your back sometime." End of the Project Gutenberg EBook of Quest on Io, by Robert Moore Williams
