The instant the deck was awash, I opened the conning-tower hatch and stepped out. In another minute the deck-hatch lifted, and those who were not on duty below streamed up the ladder, Olson bringing Nobs under one arm. For several minutes no one spoke; I think they must each have been as overcome by awe as was I. All about us was a flora and fauna as strange and wonderful to us as might have been those upon a distant planet had we suddenly been miraculously transported through ether to an unknown world. Even the grass upon the nearer bank was unearthly—lush and high it grew, and each blade bore upon its tip a brilliant flower—violet or yellow or carmine or blue—making as gorgeous a sward as human imagination might conceive. But the life! It teemed. The tall, fernlike trees were alive with monkeys, snakes, and lizards. Huge insects hummed and buzzed hither and thither. Mighty forms could be seen moving upon the ground in the thick forest, while the bosom of the river wriggled with living things, and above flapped the wings of gigantic creatures such as we are taught have been extinct throughout countless ages. “Look!” cried Olson. “Would you look at the giraffe comin’ up out o’ the bottom of the say?” We looked in the direction he pointed and saw a long, glossy neck surmounted by a small head rising above the surface of the river. Presently the back of the creature was exposed, brown and glossy as the water dripped from it. It turned its eyes upon us, opened its lizard-like mouth, emitted a shrill hiss and came for us. The thing must have been sixteen or eighteen feet in length and closely resembled pictures I had seen of restored plesiosaurs of the lower Jurassic. It charged us as savagely as a mad bull, and one would have thought it intended to destroy and devour the mighty U-boat, as I verily believe it did intend. We were moving slowly up the river as the creature bore down upon us with distended jaws. The long neck was far outstretched, and the four flippers with which it swam were working with powerful strokes, carrying it forward at a rapid pace. When it reached the craft’s side, the jaws closed upon one of the stanchions of the deck rail and tore it from its socket as though it had been a toothpick stuck in putty. At this exhibition of titanic strength I think we all simultaneously stepped backward, and Bradley drew his revolver and fired. The bullet struck the thing in the neck, just above its body; but instead of disabling it, merely increased its rage. Its hissing rose to a shrill scream as it raised half its body out of water onto the sloping sides of the hull of the _U_-33 and endeavored to scramble upon the deck to devour us. A dozen shots rang out as we who were armed drew our pistols and fired at the thing; but though struck several times, it showed no signs of succumbing and only floundered farther aboard the submarine.
