INVISIBLE ’’ BATTLESHIPS NEWEST AMERICAN IDEA. An invisible battleship—one which cannot be seen at sea when it is inside tb- horizon line—is now being striven lor bv the United States Navy. hollowing the experiments of Mr Abbot H. Thayer, qn Englishman, the Nary officials are conducting a series of tests promises to solve the problem. Air Thayer, in studying the colouration of wild animals, particularly water fowl, noted at what distance their colour enabled them to become invisible to the naked ere. and through glasses ! ast year Mr Thayer demonstrated behre N'.ivy officials that, under certain conditions, the model of a torpedo boat nainted bv him could not be seen, while a similar vessel painted battle-grey was olainlv visible. American Navy officers express the belief that it is only a question of time when sunor-Dreadnonghts can be made nramieallv invisible at the range at which natal battles are now fought. At Newoort. whore experiments are being conducted. vessels have been painted in various ways to test their visibility. The most elusive combination thus" far discovered consists of horizontal irregular serpen line lines of black naint along the sides of vessels with a background of battle-grey. The serpentine curves correspond substantially to the waves of the sea, and the mixed colours conform in nart to the mottled surface of the water. The funnels, on the other hand, are painted in irregular spirals, and it is said that destroyers painted that wav arc more nearly invisible close at hand than at a greater distance.
