Freeman's Chronicle

Sub-Marine Explosion.

Bushnell the Second--We understand a gentleman at Norwich has invented a Diving-Boat, which by means of paddles he can propel under water at the rate of 3 miles an hour, and ascend and descend at pleasure. He has made a number of experiments, & has been 3 times under the bottom of the Ramilies,--off New London. In the 1st attempt, after remaining under some time, he came to the top of the water, like the porpoise, for air, and, as luck would have it, came up but a few feet from the stern of the Ramilies, and was observed by the centinels on deck, who sung out "boat ahoy"- immediately on hearing which, the boat descended without making a reply. Seeing this, an alarm gun was fired on board the ship, and all hands called to quarters--the cable cut and the ship got under way with all possible dispatch, expecting every moment to be blown up by a torpedo. In the 3d attempt he came up directly under the Ramilies, and fastened himself and his boat to her keel, where he remained half an hour, and succeeded in perforating a hole through her copper, & while engaged in screwing a torpedo to her bottom, the screw broke, and defeated his object for that time. So great is the alarm and fear on board of the Ramilies of some such stratagem being played off upon them, that commodore Hardy has withdrawn his force from before New London, and keeps his ship under way all the time, instead of lying at anchor as formerly.
