The Esperance's enterprise was plainly not a brand-new adventure. It had been carried on for some time. They had had technical aid of the very highest caliber, but they hadn't gotten anywhere yet. It did appear that Terry had added a minor specialty to the arsenal of investigative techniques. Without the data gathered on recorder-tape, their idea of the events of two nights before would be very different. The sea would have seemed very bright, then the glowing area would have been noted to have grown smaller, and something resembling a whale would have been seen leaping high above the water. Then the brightness would have faded out. It would have been mysterious enough, but an entire aspect of the phenomenon would have gone unnoticed. There was still no answer to any of the far-reaching questions Terry had asked himself, but most of them had never been asked before. Sea noises had proved to be closely connected to whatever had to be found out. What was known about them was due to his findings. He'd established a new frame of reference.

And he'd discovered the solution of a minor problem before the problem was even stated. He had only to prove it. Then, of course, there would be other problems arising from it.

He got up, put on swimming trunks, and duck trousers over them. He slipped into a sweat shirt and went upon deck. Deirdre hailed him.

"Good morning! Everybody's over at the tracking station, arguing about the bolide that went over last night. According to the radar, it plunged into the sea, miles and miles away."

"What should it have done?" asked Terry. "I'm not familiar with meteorites. Are they planning to dive for it?"

"Hardly!" Deirdre laughed. "It landed in the Luzon Deep." She waved a hand in an inclusive gesture. "This island's on the brink of it. A bathyscaphe might go down there—in fact, I think it's scheduled; you know, the one I said was coming to Manila on the oceanographic ship? A bathyscaphe can go that deep, but it's not likely to hunt for meteorites."

"Ah," said Terry judicially. "Then what difference does it make where it hit?"

"It didn't fall the way it should have," said Deirdre. "It was spotted by space radar away out, and they tried to compute its path, but they figured it wrong. Now they're trying to make it come out right by allowing for the effect of the earth's magnetic field on a metal meteorite. They're arguing and waving equations at each other."

"Let them," said Terry. "I have trouble enough with fish. Do you think I could borrow a boat?"

"We've always been able to," said Deirdre. Then she added, "I've kept your breakfast hot. While you eat it I'll get a boat."
