“The pressure,” said I, “equalized itself. It was the same within as without.”
“Words — mere words!” he cried, shaking his lean head impatiently. “You have brought up round fish, such fish as Gastro-stomus globulus. Would they not have been squeezed flat had the pressure been as you imagine? Or look at our otter-boards. They are not squeezed together at the mouth of the trawl.”
“But the experience of divers?”
“Certainly it holds good up to a point. They do find a sufficient increase of pressure to influence what is perhaps the most sensitive organ of the body, the interior of the ear. But as I plan it, we shall not be exposed to any pressure at all. We shall be lowered in a steel cage with crystal windows on each side for observation. If the pressure is not strong enough to break in an inch and a half of toughened double-nickelled steel, then it cannot hurt us. It is an extension of the experiment of the Williamson Brothers at Nassau, with which no doubt you are familiar. If my calculation is wrong — well, you say that no one is dependent upon you. We shall die in a great adventure. Of course, if you would rather stand clear, I can go alone.”
It seemed to me the maddest kind of scheme, and yet you know how difficult it is to refuse a dare. I played for time while I thought it over.
“How deep do you propose to go, sir?” I asked.
He had a chart pinned upon the table, and he placed the end of his compasses upon a point which lies to the south-west of the Canaries.
“Last year I did some sounding in this part,” said he.
“There is a pit of great depth. We got twenty-five thousand feet there. I was the first to report it. Indeed, I trust that you will find it on the charts of the future as the «Maracot Deep».”
“But, good God, sir!” I cried, “you don’t propose to descend into an abyss like that?”
“No, no,” he answered, smiling. “Neither our lowering chain nor our air tubes reach beyond half a mile. But I was going to explain to you that round this deep crevasse, which has no doubt been formed by volcanic forces long ago, there is a varied ridge or narrow plateau, which is not more than three hundred fathoms under the surface.”
“Three hundred fathoms! A third of a mile!”
“Yes, roughly a third of a mile. It is my present intention that we shall be lowered in our little pressure-proof look-out station on to this submarine bank. There we shall make such observations as we can. A speaking-tube will connect us with the ship so that we can give our directions. There should be no difficulty in the mater. When we wish to be hauled up we have only to say so.”
“And the air?”
“Will be pumped down to us.”
“But it will be pitch-dark.”
“That, I fear, is undoubtedly true. The experiments of Fol and Sarasin at the Lake of Geneva show that even the ultra-violet rays are absent at that depth. But does it matter? We shall be provided with the powerful electric illumination from the ship’s engines, supplemented by six two-volt Hellesens dry cells connected together so as to give a current of twelve volts. That, with a Lucas army signalling lamp as a movable reflector, should serve our turn. Any other difficulties?”
“If our air lines tangle?”
“They won’t tangle. And as a reserve we have compressed air in tubes which would last us twenty — four hours. Well, have I satisfied you? Will you come?”
It was not an easy decision. The brain works quickly and imagination is a mighty vivid thing. I seemed to realize that black box down in the primeval depths, to feel the foul twice-breathed air, and then to see the walls sagging, bulging inwards, rending at the joints with the water spouting in at every rivet-hole and crevice and crawling up from below. It was a slow, dreadful death to die. But I looked up, and there were the old man’s fiery eyes fixed upon me with the exaltation of a martyr to Science. It’s catching, that sort of enthusiasm, and if it be crazy, it is at least noble and unselfish. I caught fire from his great flame, and I sprang to my feet with my hand out.
“Doctor, I’m with you to the end,” said I.
“I knew it,” said he. “It was not for your smattering of learning that I picked you, my young friend, nor,” he added, smiling, “for your intimate acquaintance with the pelagic crabs. There are other qualities which may be more immediately useful, and they are loyalty and courage.”
So with that little bit of sugar I was dismissed, with my future pledged and my whole scheme of life in ruins. Well, the last shore boat is leaving. They are calling for the mail. You will either not hear from me again, my dear Talbot, or you will get a letter worth reading. If you don’t hear you can have a floating headstone and drop it somewhere south of the Canaries with the inscription:
“Here, or Hereabouts, lies all that the fishes have left of my friend, CYRUS J. HEADLEY.”
The second document in the case is the unintelligible wireless message which was intercepted by several vessels, including the Royal Mail steamer Arroya. It was received at 3 p.m. October 3rd, 1926, which shows that it was dispatched only two days after the Stratford left the Grand Canary, as shown in the previous letter, and it corresponds roughly with the time when the Norwegian barque saw a steamer founder in a cyclone two hundred miles to the south-west of Porta de la Luz. It ran thus:
Blown on our beam ends. Fear position hopeless. Have already lost Maracot, Headley, Scanlan. Situation incomprehensible. Headley handkerchief end of deep sea sounding wire. God help us! S. S. Stratford.
This was the last, incoherent message which came from the ill-fated vessel, and part of it was so strange that it was put down to delirium on the part of the operator. It seemed, however, to leave no doubt as to the fate of the ship.
The explanation — if it can be accepted as an explanation — of the matter is to be found in the narrative concealed inside the vitreous ball, and first it would be as well to amplify the very brief account which has hitherto appeared in the Press of the finding of the ball. I take it verbatim from the log of the Arabella Knowles, master Amos Green, outward bound with coals from Cardiff to Buenos Aires:
“Wednesday, Jan. 5th, 1927. Lat. 27.14, Long. 28 West. Calm weather. Blue sky with low banks of cirrus clouds. Sea like glass. At two bells of the middle watch the first officer reported that he had seen a shining object bound high out of the sea, and then fall back into it. His first impression was that it was some strange fish, but on examination with his glasses he observed that it was a silvery globe, or ball, which was so light that it lay, rather than floated, on the surface of the water. I was called and saw it, as large as a football, gleaming brightly about half a mile off on our starboard beam. I stopped the engines and called away the quarter-boat under the second mate, who picked the thing up and brought it aboard.
“On examination it proved to be a ball made of some sort of very tough glass, and filled with a substance so light that when it was tossed in the air it wavered about like a child’s balloon. It was nearly transparent, and we could see what looked like a roll of paper inside it. The material was so tough, however, that we had the greatest possible difficulty in breaking the ball open and getting at the contents. A hammer would not crack it, and it was only when the chief engineer nipped it in the throw of the engine that we were able to smash it. Then I am sorry to say that it dissolved into sparkling dust, so that it was impossible to collect any good-sized piece for examination. We got the paper, however, and, having examined it and concluded that it was of great importance, we laid it aside with the intention of handing it over to the British Consul when we reached the Plate River. Man and boy, I have been at sea for five-and-thirty years, but this is the strangest thing that ever befell me, and so says every man aboard this ship. I leave the meaning of it all to wiser heads than mine.”
