We expelled the bodies through the double hatches and were alone in the U-29. Klenze seemed very nervous, and drank heavily. It was decided that we remain alive as long as possible, using the large stock of provisions and chemical supply of oxygen, none of which had suffered from the crazy antics of those swine-hound seamen. Our compasses, depth gauges, and other delicate instruments were ruined; so that henceforth our only reckoning would be guesswork, based on our watches, the calendar, and our apparent drift as judged by any objects we might spy through the portholes or from the conning tower. Fortunately we had storage batteries still capable of long use, both for interior lighting and for the searchlight. We often cast a beam around the ship, but saw only dolphins, swimming parallel to our own drifting course. I was scientifically interested in those dolphins; for though the ordinary Delphinus delphis is a cetacean mammal, unable to subsist without air, I watched one of the swimmers closely for two hours, and did not see him alter his submerged condition.
With the passage of time Klenze and I decided that we were still drifting south, meanwhile sinking deeper and deeper. We noted the marine fauna and flora, and read much on the subject in the books I had carried with me for spare moments.
I could not help observing, however, the inferior scientific knowledge of my companion. His mind was not Prussian, but given to imaginings and speculations which have no value. The fact of our coming death affected him curiously, and he would frequently pray in remorse over the men, women, and children we had sent to the bottom; forgetting that all things are noble which serve the German state.
After a time he became noticeably unbalanced, gazing for hours at his ivory image and weaving fanciful stories of the lost and forgotten things under the sea. Sometimes, as a psychological experiment, I would lead him on in these wanderings, and listen to his endless poetical quotations and tales of sunken ships. I was very sorry for him, for I dislike to see a German suffer; but he was not a good man to die with. For myself I was proud, knowing how the Fatherland would revere my memory and how my sons would be taught to be men like me.
On August 9, we espied the ocean floor, and sent a powerful beam from the searchlight over it. It was a vast undulating plain, mostly covered with seaweed, and strown with the shells of small molluscs. Here and there were slimy objects of puzzling contour, draped with weeds and encrusted with barnacles, which Klenze declared must be ancient ships lying in their graves.
He was puzzled by one thing, a peak of solid matter, protruding above the ocean bed nearly four feet at its apex; about two feet thick, with flat sides and smooth upper surfaces which met at a very obtuse angle. I called the peak a bit of outcropping rock, but Klenze thought he saw carvings on it. After a while he began to shudder, and turned away from the scene as if frightened; yet could give no explanation save that he was overcome with the vastness, darkness, remoteness, antiquity, and mystery of the oceanic abysses. His mind was tired, but I am always a German, and was quick to notice two things; that the U-29 was standing the deep-sea pressure splendidly, and that the peculiar dolphins were still about us, even at a depth where the existence of high organisms is considered impossible by most naturalists. That I had previously overestimated our depth, I was sure; but none the less we must still be deep enough to make these phenomena remarkable. Our southward speed, as gauged by the ocean floor, was about as I had estimated from the organisms passed at higher levels.
