Moving to the radio, the old man fumbled with knobs and switches and pounded on the cabinet with his fist. "This radio's deader than a asteroid!" he yelled. "First the teletype and now the radio. I'm supposed to report all ships to Titan, but how can I with no equipment? Maybe that's your ship come hunting you. What did you say your name is?"

"Henry," said Henry.

"Henry, huh? My name's Ranjit. I better get up to the big valve. That ship'll be clinching in a minute."

"What does that sign mean?" said Henry, seizing the old man's bony wrist.

"Sign? Oh, there over the desk? I just put that there to confuse people. It's a puzzle that spells out something in an old-time language, Latin maybe. Christian Huygens published that way back in 1655. He used a puzzle while he was checking some more. He was the first man to figure out what was around Saturn. It means something like, 'There's a flat ring that's inclined to the ecliptic that circles the planet without touching it.' Well, let go of me. I've got to see about that ship."

"Just stay here and be calm, Ranjit," Henry said.

"What?"

"Be good, and you won't get hurt."

"Get hurt? What are you talking about, Henry? That's no way to talk to a fellow that saved your life. If it hadn't been for me, you'd still be falling. You were slower than the sweeper. I saved your life!"

Henry blushed in sudden shame and released Ranjit's arm. "Why, why, I—I guess you did!" he stammered.
