Dawn came. Terry was already on deck when the Esperance threaded her way into a small harbor. There were palm trees along the shore, and there was a Philippine town with edifices ranging from burnt brick to stucco to mere nipa huts on its outskirts. Two-man fishing boats were making their way out from the shore on which they'd been beached. From somewhere came the staccato, back-firing noise of an old automobile-engine being warmed up for the day's work. It would undoubtedly be the bus for Manila. But it was not thinkable that Terry should take it, now.

The yacht dropped anchor and lay indolently at rest while her crew breakfasted and the morning deck routine was being performed. Then Deirdre appeared in shore-going clothes of extreme femininity. Davis too was dressed otherwise than as usual.

"We're going ashore to the shipyard," he told Terry. "If you'd like to come—"

"I've something to do here," said Terry.

Two of the crew-cuts got a boat overside and headed it for the shore. Terry got out the recorder and the submarine ear and horn. He set up his apparatus for a test. Tony came from belowdecks and watched. Then he came closer.

"If I can help," he said tentatively.

"You can," Terry told him. "But let's listen to what the fish are saying, first."

He dropped over the submarine ear and started the recorder to play what it picked up, but without recording it. Sounds from underwater came out of the speakers. The slappings of tiny harbor-waves against the yacht's planking; the chunking, rhythmic sound of oars from a fishing boat which was rowing after the half-dozen that had gone out earlier; grunting sounds. Those were fish.

Terry listened critically, and Tony with interest. Then Terry brought out the fish-driving paddle. He turned on the tape, now, to have a record of the sound the paddle made.

"Whack this on the water," he suggested, "and we'll hear how it sounds."
