"Certainly," said Terry. "_Seguramente!_" He added in Spanish: "We'll lend you a short-wave contact with Manila to make any complaints you please. I'm sure all the other fishing boats will be glad to hear where you've been catching fish, and where you've found the fish have moved to! Calm yourself, Capitán, and help yourself to the fish of the lagoon, and any time you want to call Manila we'll arrange it!" He moved away. He went back to the electronics shop, while Morton and Davis and the others talked encouragingly to Capitán Saavedra. Presently they suggested that he accept their hospitality, and the Capitán and his oarsmen went up to the dining hall, where they were served dinner, and a more friendly mood developed. In time the Capitán said happily that he would wait till sunrise to lower his nets, because he didn't want to risk losing them on the coral heads. A few drinks later the Capitán boasted about his own system of fishing, as practised by _La Rubia_. The starving condition of his crew's wives and children ceased to be mentioned. In the presence of so accomplished a liar, nobody of the tracking station staff mentioned a giant squid hauled partly, but only partly, out of the water. They suspected that he would not believe it. They were sure that he would top their real feat by an imaginary one. So the four crew-cuts listened politely, and fed him more drinks, and learned much. In the workshop the most unlikely device Terry'd described took form. In effect, it was an underwater horn which was much more powerful than it looked. Submerged, and with power from a group of amplifiers in parallel, it would create a tremendous volume of underwater noise. That sound would run through a tube shaped like a gun-barrel. It would travel in a straight line, spreading only a little. The same projection tube could also send out the tentative beep-beep-beep of sonar gear, or the peculiar noise a depth-finder makes. So the instrument could search out a distance or find a target, and then fling at it a beam of humming torment equal to bullets from a machine gun. It would have taken Terry, alone, a long time to build. But he had three assistants, two of whom were very competent. By dawn, they had it ready to be mounted upon the _Esperance_. It was placed hanging from the bow, mounted on gimbals, so that it could point in any direction. It was firmly fixed to the yacht's planking. There was plenty of activity on _La Rubia_, too, at daybreak. That squat and capable fishing boat prepared to harvest the fish in the lagoon. She got her nets over. She essayed to haul them. Some got caught on the coral heads rising from the lagoon's bottom toward the surface. Capitán Saavedra swore, and untangled them. He tried again. Again coral heads baulked the enterprise. The nets tore.
