The last vestige of the Silver Menace was turned to yellowed water within a month. Submarine sirens, carefully tuned to precisely the pitch that would cause the tiny shells to shatter themselves, were hastily set aboard huge numbers of fast steamers, that swept the ocean in patrols, clearing the sea as they went. Whenever the clear note was poured out by one of the under-water sirens the silvery animalcules died in their myriads. Slowly, as the evil smell of their bodies dissipated, the inhabitants of the Atlantic Ocean came back to their normal haunts. By shoals and schools, by swarms and in tribes, the fishes came down again from the North. A week after the destroying steamers began their patrol rain fell on the Atlantic coast. The abnormally dry air above the ocean took up water avidly and poured it down on the parched earth with a free hand. The ocean, too, took up again its former function of furnishing cool breezes during the day and warm breezes at night. The seashore became once more a place of charm and delight. At least Davis and Nita found it so. Davis was being waited upon with decorations and honorary degrees, with the freedom of cities and medals of honor from learned societies. At each presentation solemn speeches were made in which he was told how superlatively clever he was. Remembering the purely accidental nature of his discovery, he found it difficult to keep from laughing. These things were tiresome, but were not active nuisances until after his marriage. When he found that he and Nita would not be left alone, that no matter how scrupulously they concealed their identity it was sooner or later discovered and they were interviewed and written up in special articles for the newspapers he grew annoyed. The climax came on a beautifully moonlit night at a seashore resort where they were quite confident they would not be discovered. The beach was like silver, and the waves were dark and mysterious, except where the reflection of the moon glittered on their shining sides. Davis and Nita, forgetting the world and devoutly hoping that they were by the world forgot, sat and looked at the moon and played idly in the sand and told each other the eternal foolishnesses that are probably the truest wisdom. They were utterly happy just being alone with each other. A dark figure looked up over and coughed. They started. "You are Flight Commander and Mrs. Davis?" said a voice deprecatingly. Davis groaned and admitted it. "Our little villagers learned that you are visiting here, and a banquet has been prepared in the pavilion in your honor. Won't you do us the honor to attend?" Davis muttered several words under his breath, for which Nita later reprimanded him, and rose heavily.
