"'Nonsense, Green!' I said sharply. 'Don't talk any more such foolishness or I'll have you ironed. You've been drinking so much that you are seeing things, and I won't have the crew disturbed by your crazy talk.'

"'You won't think it's talk when those big eyes stare into yours to-night, Mr. Mitch.e.l.l, and that body twists around you and squeezes the life out of you. I don't care whether you iron me or not; I know that I'm doomed and so is everyone else; but I won't talk about it, sir. The crew might as well rest easy while they can, for there's no escape if we have to stay out here to-night.'

"'Well, be sure you keep a tight mouth then,' I said, and left rather hurriedly. I was in a cold sweat, for his air of conviction, together with what I had seen, had shaken me pretty badly. I heard the watch changing up above, and knew there would be men in the forecastle in a minute. I didn't want to face them right then.

"Mr. Fulton reported everything quiet when I went on deck to relieve him, and although I surveyed the water through a night gla.s.s for as far as I could see, there was nothing out of the way. The Coast Guard's lights were shining less than a quarter of a mile away, and things looked peaceful enough. The wind had gone down with the sun; the sea was almost gla.s.sy, and there was a bright moon.

"After going around the ship, I relieved all of the watch except two men for lookouts, and sent them below to get a good night's sleep. If I hadn't done that, some of them might be alive now.

"I paced the deck for an hour trying to quiet my nerves, but really getting more nervous every minute. Three bells struck and I walked forward and leaned on the rail to watch the water. I saw a peculiar swirl as though some large body were coming to the surface from below, and then I saw--it.

"Dr. Bird, I take a drink once in a while when I am on sh.o.r.e, but never at sea and never in excess, and I know it wasn't a vision of drink delirium. I felt perfectly normal aside from my nervousness, and I don't think it was fever. Either I saw it or I am insane, for it is as vivid to me as though I were standing on the _Arethusa's_ deck and that monstrous horror was rising once more before my eyes."

The seaman's face had become drawn and white as he talked, and drops of sweat were trickling from his chin. Carnes sat forward absorbed in his narrative while Dr. Bird sat back with a glitter in his black eyes and an expression of great attention on his face.

"Go on, Mr. Mitch.e.l.l," the doctor said soothingly. "Tell me just what you saw."

Mitch.e.l.l shuddered and glanced quickly around the laboratory as though to a.s.sure himself that he was safe within four walls.

"From the surface of the sea," he went on, "rose a ma.s.sive body, black, and of the appearance of wet leather. It must have been a couple of hundred yards across, although the size of objects is often magnified by moonlight and my terror may have added to its size. In the midst of it were two great discs, thirty feet across, which glowed red with the reflected moonlight. It stared for a moment and then rose higher until it towered above the ship; and then I saw, or thought I saw, a huge gaping beak like a parrot's. It was as Green had described it, large enough to bite the _Arethusa_ in half, and she was a ship of three thousand tons.

"I was frozen with horror and couldn't move or cry out. As I watched, I saw the long snake-like body emerge from the water, and the estimate I had made of the size in the afternoon seemed pitifully inadequate.

Presently a second and a third snake arose from the water, and then more, until the whole sea and the air above it seemed a writhing ma.s.s of huge snakes. I remember wondering why the watch of the Coast Guard cutter didn't sound an alarm, and then I realized that the thing had arisen on our port side and the cutter was on the starboard.

"The ma.s.s of snakes writhed backward and forward, and then two of them rose in the air and hung over the ship. I could see the under side and I saw what Green had called the scars where the sharks had attacked. They were great cup-shaped depressions with vile white edges, and they did resemble huge sores or ulcers. They wavered over the ship for an instant, and then both of them dropped down on the deck.

"I found my voice and I think that I gave a yell, but even as I opened my mouth, I realized the futility of it. The _Arethusa_ was sucked down into the sea as though it had been a tiny chip. I saw the water rising to the rail, and I think I cried out again. The ship tilted and I felt myself falling. The next thing I knew was when I was in the hospital and was told that I had been raving for a week. I was afraid to tell my story for fear I would be put in an asylum, so I kept a tight tongue in my head until I was discharged."

Dr. Bird mused for a moment as the seaman's voice stopped.

"You cried out all right, Mr. Mitch.e.l.l," he said. "You gave two distinct shouts, both of which were heard by the watch on the _Wren_, the Coast Guard cutter. They reported that at 1:30, the _Arethusa_ sank without warning. As soon as he heard your shouts, the watch gave the alarm and the crew piled on deck. The _Arethusa_ was gone completely and the _Wren_ was tossing about like 'a chip in a whirlpool' as they graphically described it. The _Wren_ had steam up and they fought the waves and steamed over your anchoring ground looking for survivors, but they found none. The sea gradually subsided and they did the only thing they could do--dropped a buoy, to guide the salvage people, and radioed for a.s.sistance. The _Robin_ came out and joined them, and both cutters stood by until daylight, but nothing unusual was seen. The insurance people are trying to salvage the wreck now, but so far they have made little headway."

"That brings me to the rest of the story, the part that made me decide to come to you, Doctor," said the seaman. "Did you see what happened to the divers yesterday?"

Dr. Bird nodded.

"I saw a brief account of it," he said. "It seems that two of them were lost through their lines getting fouled and their air connections severed in some way. I don't believe the bodies have been recovered yet."

"They never will be recovered, Doctor. I was discharged from the hospital yesterday and the papers were just out with an account of it. I went down to the dock where the _John MacLean_, the salvage ship, ties up, and I talked to Captain Starley who commands it. I have known him casually for some years, although not intimately, and he gave me a few more details than the press got. He didn't connect me up at first with the Mitch.e.l.l who was reported lost on the _Arethusa_.

"The first man to go down from the _MacLean_ was Charley Melrose, an expert diver. He went down in a pressure outfit to the bottom and started to work. Everything was going along fine until the telephone suddenly rang and the man who answered it heard him say, 'Raise me, for G.o.d's sake! Hurry!' The signal for raising was given, but they hadn't got him more than thirty feet from the bottom before there came a tug on the line and he was gone! The air line, the lifting cable and the telephone cord floated free and were reeled in. Melrose had been plucked off the end of that line as you or I would pluck off a grape."

Dr. Bird leaned forward with the curious glitter again in his eye.

"Go on," he said tersely.

"Blake, the other diver, donned a suit and insisted on being lowered at once. Starley tried to dissuade him but he insisted on going down. They lowered him over the side with a twelve-foot steel-shod pike in his hand. He never got to the bottom. He had not been lowered more than a hundred feet when a scream came over the telephone, and again there was a jerk on the lines which threatened to wreck the reel--and the line came aboard with no diver on the end of it. At the same time, Starley told me, the sea boiled and churned as though the whole bottom were coming up, and his ship was tossed about as though it were in a violent storm, although it was calm enough for forty fathom salvage work and that is pretty quiet, you know. Half the time his screws were out of water and he had a hard time to keep from being capsized. He fought his way out of the disturbed area, and as soon as he did, it started to quiet down, and in ten minutes it was calm again.

"Starley was pretty badly shaken and besides he had lost both of his divers, so he came in and I saw him at the dock. When I heard his yarn, I took him into my confidence and told him what I had seen and that I proposed coming to you and asking your advice. I was afraid until I heard his story that it was merely a vision that I had had, but it certainly was no vision that plucked those two divers off their lines."

"Has Captain Starley told that story to anyone else yet?"

"No, Doctor, he hasn't. He promised not to talk until after I had seen you. I'll vouch for him; he'll keep his word through anything; and he is keeping his whole crew on board until he hears from me."

Dr. Bird sprang to his feet.

"Mr. Mitch.e.l.l," he said energetically, "you have shown excellent judgment. Wire Captain Starley that you have seen me and that he is to hold his crew on board and to talk to no one until I get there. Carnes, telephone the Chief of Naval Operations and ask him to receive me in conference at once. Have him get the Secretary of the Navy in, too, if he is available. When you have finished that, telephone Bolton that you will be away from Washington indefinitely."

"I'll telephone Admiral Buck for you, Doctor, but I don't dare telephone any such message to Bolton; he'd take my head off. He has been running the whole service ragged lately, and this is my first afternoon off duty in a fortnight."

"What's the trouble, a flood of new counterfeits?"

"No, the counterfeit division is getting along all right. In point of fact, they have lent us a dozen men. The trouble is a sudden big increase in Communist activity throughout the country, with the Young Labor party behind it. Bolton has been pretty jumpy since that Stokowski affair last August and he is afraid of another attempt of some sort on the President."

"The Young Labor party? I thought that gang was bankrupt and out of business, since the Coast Guard broke up their alien smuggling scheme."

"They were down and out for a while, but they are in funds again--and how! They must have three or four millions at least."

"Where did they get it?"

"That's what we have been trying to find out. The leaders have presented bars of gold to a dozen banks throughout the country and demanded specie. The banks shipped the gold to the mint and it was good gold, nine hundred and twenty-five fine. What we are trying to find out is how that gold got into the United States."

"A shipment of that size should be easy to trace."

"It would seem so, but it hasn't been. We have accounted for every pound of every shipment that has come in through a port of entry, and we have checked almost that close on the output of every mine in the United States. If the gold came from Russia, it would have had to cross Europe, and we can't get any trace of it from abroad. It looks as though they were _making_ it."

Dr. Bird rubbed his head thoughtfully.

"Possible, but hardly probable," he said. "How much did you say they had?"

"Over three millions in thirty-pound bars. Each bar shows signs of having a mint mark chiselled off, but that don't help much for they have done too good a job. It has us pretty well bluffed."

Again Dr. Bird rubbed his head.

"Telephone Admiral Buck, and then phone Bolton and tell him exactly what I told you to: that you will be away indefinitely. When he gets through exploding, tell him that you are going with me and that possibly, just barely possibly, we might be on the trail of that gold shipment."
