I took off one leaden shoe and loosened the other, ready to kick away. I shut the escape-valve. I cut the cord with my axe on the rock I had been sitting on, and then, when the air had blown out my dress to most corpulent proportions, I took the decisive stroke. I chopped through the air-pipe. I stuffed it as well as possible and tied it in some sort of a knot--it was _very_ stiff--in a great hurry, and then--I kicked off the leaden shoe. Never, never, never--even if I live on Jupiter after this planet is blown to shivers--shall I forget the result of my forlorn-hope dodge. I kicked off the shoe, as I have said, and, in an instant, the whole universe of waters turned upside down and swirled away beyond my head. In sober fact, _I_ had turned upside down--as I might have known I should do, if only I hadn't been a bigger fool than ever. [Illustration: "I HAD TURNED UPSIDE DOWN."] Of course, the moment my leaden shoes went, _down_ came my copper head-pot, being my heaviest part, and up went my feet. I had a pretty quick rise, certainly, but I prefer not to recall my feelings during the rush. I can quite understand now why a rise in the world makes some people giddy. All that I had before felt of amazement and horror, I now felt multiplied by fifty and squeezed into about two seconds, so that they felt like ten hours. Up through that awful water and those moving shadows I went, feeling that I was in reality held still, like a man in a nightmare. When at last I stopped, I felt that it was but a matter of moments, and the air would leak away through that cut tube, and I should go down again, still head under, for the last time, to die in that grisly combination of mackintosh and copper kettle; also I felt choking, stifling, when--something had me roughly by the ankle, and I was dragged, a wretched rag of misplaced ambition, into a boat. The appearance of my legs sticking out above water had, it seemed, caused intense amusement among the boat's crew--a circumstance which probably ought to have gratified me, although it didn't. [Illustration] I have little more to add, except that I shudder, to this day, whenever I see an acrobat standing on his head, because it is so graphically remindful. But, if anybody is thinking of going in for diving by way of placid enjoyment, I shall be delighted to treat with him for the sale and purchase of a most desirable diving-dress in unsoiled condition, cut in the most fashionable style, with a fascinating copper helmet and commodious collar, and a neat label for the chest. The shoes will not be included in the bargain, having been inadvertently left in a damp place. _FROM BEHIND THE SPEAKER'S CHAIR._ XIII. (VIEWED BY HENRY W. LUCY.) [Sidenote: THE EMPTY SEAT.]
