The diving‐bell proper has been much improved by another Frenchman, M. Payerne. His “Submarine Hydrostat” will descend or fall at the will of those inside. Thirty men may work in it with ease for a number of hours without inconvenience. It is, therefore, of great service in clearing ports, and in facilitating the execution of other submarine work. “The principle of the machine is very ingenious. Externally, it has the appearance of one large rectangular box, surmounted by another smaller one, completely closed in except at the bottom. The interior consists of three principal compartments. The _hold_ communicates by a large shaft with the upper compartment. Between these is a third compartment, or _orlop deck_, which only communicates with the others by means of stop‐ cocks. The hydrostat is twenty feet in height, and its base, which has the bottom of the sea for a floor, covers an area of 625 square feet. It may be made to rise and fall at will, and it will readily float about like a raft.” This ingenious machine has proved of much service. The port of Fécamp was choked up with shingle, which closed it against all vessels beyond a certain tonnage. The hydrostat was employed, and the port cleaned, and again opened to commerce. The old divers are fond of recounting the glories of their craft, and are specially impressed with any information as to the fate of the vessels of the Armada. This spirit has been fostered no less by the successes of the ancestor of the Mulgraves than by the good fortune of John Gann, of Whitstable. The old diver was, many years since, employed on the Galway coast, and used to pass his evenings in a public‐house frequented by fishermen. One of these men, repeating a tradition which had long existed in the district, told Gann that one of the Spanish vessels had been wrecked not far from that coast, and intimated that he himself could point out the spot. Gann, having finished his special job, made terms with the fisherman, and they were both out for many weeks dragging the spot indicated for any traces of the wreck. They were at last rewarded by coming upon obstructions with their grapnels. Gann brought out his diving apparatus, and sure enough the truth of the tradition was vindicated by the finding of a number of dollars, which had originally been packed in barrels. The barrels, however, had rotted away, and left the gold stacked in barrel shape. With the money so recovered John Gann built at Whitstable, his native place, a row of houses, which, to commemorate the circumstance, he called Dollar Row.
