Across theplate of scintillating glass that was the sea moved rows of toy ships,tipped by the gleaming, one-fifth-mile long shape of a dirigible, ofwhose three scout planes Chris's was the leader. As he watched, thesecond scout dropped from the plane rack beneath the dirigible's sleekunderside and went streaking away, followed by the third, in responseto the Admiral's order of: "Proceed ahead to locate the enemy'sposition."A grin relaxed Chris Travers' tanned, boyish face. His narrowed grayeyes swept the horizon. Below it somewhere lay hidden the ranks of theBlack Fleet, complete with its own destroyers, submarines, cruisers,battleships, aircraft carriers and the ZX-2, sister dirigible of theBlue Fleet's ZX-1. Chris spurted the scout ahead and murmured:"This war game's goin' to be a big affair--the biggest yet!"It was. The Atlantic Fleet of the United States Navy, termed "Blue"for convenience, had been assigned to guard the Panama Canal; thePacific Fleet, "Black," to attack it. The cream of America's seaforces had been assembled for that week of March, 1935, all the wayfrom crabby little destroyers to the two newly completed monarchs ofthe air, the twin dirigibles, fresh from the hangars at Akron, athousand feet each in length and loaded with the latest offensive anddefensive devices developed by Government laboratories.
