By profession I am a diver, and the next day I was engaged to search for the diamond bracelet of Signora Rochita. I had a copy of the chart, and having hired a small schooner, with several men who had been my assistants before, and taking with me all the necessary accoutrements and appliances, I set out for the spot indicated, and by afternoon we were anchored, we believed, at it or very near it. I lost no time in descending. I wore, of course, the usual diver's suit, but I took with me no tools nor any of the implements used by divers when examining wrecks; but I carried in my right hand a brilliant electric lamp, connected with a powerful battery on the schooner. I held this by an insulated handle, in which there were two little knobs, by which I could light or extinguish it. [Illustration: "WAVING HER LACE HANDKERCHIEF."] The bottom was hard and smooth, and lighting my lamp, I began to look about me. If I approached the bracelet I ought to be able to see it sparkle, but after wandering over considerable space, I saw no sparkles nor anything like a bracelet. Suddenly, however, I saw something which greatly interested me. It was a hole in the bottom of the ocean, almost circular, and at the least ten feet in diameter. I was surprised that I had not noticed it before, for it lay not far from the stern of our vessel. Standing near the rocky edge of the aperture, I held out my lamp and looked down. Not far below I saw the glimmering of what seemed to be the bottom of this subterranean well. I was seized with a desire to explore this great hole running down under the ordinary bottom of the sea. I signalled to be lowered, and although my comrades were much surprised at such an order, they obeyed, and down I went into the well. The sides of this seemed rocky and almost perpendicular, but after descending about fifteen feet, they receded on every side, and I found myself going down into a wide cavern, the floor of which I touched in a very short time. Holding up my lamp, and looking about me, I found myself in a sea cave of some thirty feet in diameter, with a domelike roof, in which, a little to one side of the centre, was the lower opening of the well. I became very much excited; this was just the sort of place into which a bracelet or anything else of value might be expected to have the bad luck to drop. I walked about and gazed everywhere, but I found nothing but rocks and water.
