Fourteen hours later the _Esperance_ made ready to sail from Thrawn / Island. Her purpose was to carry the plastic objects to Manila, where / they would be turned over to specialized laboratories to be studied. / Five such objects had been found before: one in the Thrawn Island / lagoon, while the satellite-tracking station was under construction, and / four attached to exotic fish brought to market by the commercial fishing / boat _La Rubia_. Now there were eight more, of four different kinds. To / the laboratories would go Terry's observation that one kind of these / objects absorbed sound at audible frequencies and retransmitted it at / much higher ones, but only under water. All this was very interesting / and very puzzling.
But a serious disturbance had arisen at the tracking station.
