Pino's first invention was a submarine boat which was tested with brilliant success before putting it into service at Vigo Bay. For the preliminary work of treasure finding, he perfected his hydroscope, a kind of sea telescope consisting of a floating platform from which depend a series of tubes ending in a chamber equipped with electric lamps, lenses and reflectors, like so many gigantic eyes through which the observer is able to view the illuminated bottom of bay or ocean. To lift the galleons bodily is Pino's plan, and he has devised what he calls "elevators" or clusters of great bags of waterproofed canvas each capable of raising forty tons in the water when pumped full of air. These are placed in the hull of the sunken ship or attached outside, and when made buoyant by means of powerful air pumps, exert a lifting force easily comprehended. In addition, this ingenious Italian engineer, who has made a science of treasure seeking, makes use of metal arms capable of embracing a rotting, flimsy hull, huge tongs which are operated by a floating equipment of sufficient engine power to lift whatever is made fast to. The Japanese government successfully employed his submarine inventions in raising the Russian war ships sunk at Port Arthur. Already one of the Spanish galleons has been brought to the surface of Vigo Bay, but she happened to have been laden with costly merchandise instead of plate, and her cargo was long since ruined by water and corrosion. The list of articles recovered during the searches of recent years is a fascinating catalogue to show that the story of the lost fleet is a true romance of history. I quote Iberti who dwells with so much joyous enthusiasm over "the anchors, including that of the _Misericordia_, of Santa Cruz, guns of different caliber, wood of various kinds, thirty gun carriages, wheels, mortars, silver spoons, mariner's compasses, enormous cables, innumerable balls and bombs, statuettes of inlaid gold, magnificently engraved pipe holders, Mexican porcelain, tortas, or plates of silver, some weighing as much as eighty pounds; gold pieces stamped by the Royal Mint of Mexico and ingots from Peru." ====================================================================== [Illustration: Cannon of the treasure galleons recovered by Pino from the bottom of Vigo Bay.] Hydroscope invented by Pino for exploring the sea bottom and successfully used in finding the galleons of Vigo Bay.

It bears the signature of His Excellency Don Jose Ferrandiz, Minister of the Royal Navy, and was granted on August 24, 1907, to be in force until 1915. The wording runs thus:
