SIG. PINO'S SUBMARINE INVENTIONS.
Italy has another inventor whose name seems likely to become as famous as Marconi's. Sig. Pino's inventions, described in the Contemporary Review by Dr. Carlo Iberti, promise to give mankind a complete sovereignty of the seas—of all the wealth as well as all the scientific mysteries hidden in their deepest depths. They include a submarine boat and a new photographic apparatus of wonderful power, which he calls “the hydroscope.” The boat is a small affair, devoid of utility in war, but capable of carrying two persons to any depth, and of being held there immovable and in perfect equilibrium for any length of time. Its two occupants can work in it on the bed of the sea for twelve hours continuously without needing to return to the surface for air. Every object is clearly seen from it at any depth through windows made of special crystal, and it can move freely on the floor of the ocean on an ingenious single wheel propelled by an electric-driven screw. The hydroscope enables its operator, standing in an open boat on the surface, to take clear photographs of the sea's bed and all the objects thereon for an extensive area around the operating point. It illuminates the depths and brings their contents within reach of the camera. If Sig. Pino's claims are made good the incalculable riches buried since time began in the fathomless caverns of Neptune, including the great Athenian sculptures sunk in the Archipelago in the Pompeian wars, will be recovered without great difficulty. The addition in that case to the world's stock of gold will be enormous.—N. Y. World.
