"About five hundred miles east of Sancerre Bay."

That meant we must be at least a thousand miles east of the bay. I could see how that happened. Both times the boat had surfaced, it had gone straight up, lift and drive operating together. There is a constant wind away from the sunlight zone at high level, heated air that has been lifted, and there is a wind at a lower level out of the dark zone, coming in to replace it. We'd gotten completely above the latter and into the former.

There was some yelling outside, and then I could hear Hans Cronje:

"Rocket's ready for vertical launching. Ten seconds, nine, eight, seven, six, five, four, three, two, one; rocket off!"

There was a whoosh outside. Clifford, at the radio, repeated: "Rocket off!" Then it banged, high overhead. "Did you see it? he asked.

"Didn't see a thing," Feinberg told him.

"Hey, I know what they would see!" Tom Kivelson burst out. "Say we go up and set the woods on fire?"

"Hey, that's an idea. Listen, Mahatma; we have a big forest of flowerpot trees up on a plateau above us. Say we set that on fire. Think you could see it?"

"I don't see why not, even in this moonlight. Wait a minute, till I call the other ships."

Tom was getting into warm outer garments. Cesário got out the arc torch, and he and Tom and I raced out through the hut and outdoors. We hastened up the path that had been tramped and dragged to the waterfall, got the lifters off the logs, and used them to help ourselves up over the rocks beside the waterfall.
