The Gyroscope Miracle from Tracyton
A local invention aims to revolutionize seafaring by creating an artificial horizon, allowing ships to navigate through dense fog.
The story, cleaned up

Two residents of Seattle have been granted patents both in America and England for an invention called the 'gyroscope artificial horizon.' This instrument enables a navigator to take an observation at sea without reference to the natural horizon, which has never been possible before. Capt. Joshua N. Howe, of Tracyton, perfected the instrument after fifteen years of experimenting, and in conjunction with Charles E. Crane, of Seattle, has secured international patents. The device uses a mirror revolved at 3,000 revolutions per minute, balanced on a steel point with weight underneath to keep it perfectly horizontal, independent of the vessel's roll. The U.S. Navy tested the prototype aboard the USS Monterey in Seattle, and officers praised its ability to allow for accurate navigation and gunnery in adverse conditions where the natural horizon is obscured by fog or mist.
“The liability of a ship to strike a rocky coast where fog or mist obscures the natural horizon is one of the greatest dangers to navigation.”
This 1891 invention highlights the maritime ingenuity of the Puget Sound region, a hub for naval technology that continues today through regional aerospace and marine engineering. The 'artificial horizon' solved a life-or-death problem for mariners in the notoriously foggy Pacific Northwest waters, foreshadowing modern GPS and inertial navigation systems.
