this time, the throat of the third. My beam of light showed palely red, for a moment, and the body of the Rorn toppled slowly to the bed of the ocean.
The two shark-faced creatures were hammering at me with their fists, dragging at my arms and legs, but I plunged on desperately towards Mercer. Myriads of fish, all shapes and colors and sizes, attracted by the light, swarmed around us.
"Good boy!" Mercer commended. "See if you can break this last flask of acid, here at my waist. See – "
With a last desperate plunge, fairly dragging the two Rorn who tugged at me, I fell forward. With the clenched steel talons of my right hand, I struck at the silvery flask I could see dangling from Mercer's waist. I hit it, but only a glancing blow; the flask did not shatter.
"Again!" commanded Mercer. "It's heavy annealed glass – hydrocyanic acid – terrible stuff – even the fumes – "
I paid but slight heed. The two Rorn dragged me back, but I managed to crawl forward on my knees, and with all my strength, I struck at the flask again.
This time it shattered, and I lay where I fell, sobbing with weakness, looking out through the side window of my head-piece.
The five Rorn seemed to suddenly lose their strength. They struggled limply for a moment, and then floated down to the waiting sand beneath us.
"Finish," remarked Mercer coolly. "And just in time. Let's see if we can find our way back to the Santa Maria."
We were weary, and we plodded along slowly, twin trails of air-bubbles like plumes waving behind us, rushing upwards to the surface. I felt strangely alone at the moment, isolated, cut off from all mankind, on the bottom of the Atlantic.
"Coming to meet you, all of us," Imee signaled us. "Be careful where you step, so that you do not walk in a circle and find again the Place of Darkness. It is very large."
"Probably some uncharted deep," threw in Mercer. "Only the larger ones have been located."
For my part, I was too weary to think. I just staggered on.
A crowd of slim, darting white shapes surrounded us. They swam before us, showing the way. The five patriarchs walked majestically before us; and between us, smiling at us through the thick lenses of our headpieces, walked Imee. Oh, it was a triumphal procession, and had I been less weary, I presume I would have felt quite the hero.
I mee pictured for us, as we went along, the happiness, the gratefulness of her people. Already, she informed us, great numbers of young men were clearing away the bodies of the dead Rorn. She was so happy she could hardly restrain herself.
A dim skeleton shape bulked up at my left. I turned to look at it, and Imee, watching me through the lights of my head-piece, nodded and smiled.
Yes, this was the very hulk by which she had been swimming when the shark had attacked her, the shark which had been the cause of the accident. She darted on to show me the very rib upon which her head had struck, stunning her so that she had drifted, unconscious and storm-tossed, to the shore of Mercer's estate.
I studied the wreck. It was battered and tilted on its beam ends, but I could still make out the high poop that marked it as a very old ship.
"A Spanish galleon, Mercer," I conjectured.
"I believe so." And then, in pictured form, for Imee's benefit, "It has been here while much time passed?"
"Yes." Imee came darting back to us, smiling. "Since before the Teemorn, my people were here. A Rorn we made prisoner once told us his people discovered it first. They went into this strange skeleton, and inside were many blocks of very bright stone." She pictured quite clearly bars of dully-glinting bullion. Evidently the captive had told his story well.
"These stones, which were so bright, the Rorn took to their city, which is three swims distant." How far that might be, I could not even guess. A swim, it seemed, was the distance a Teemorn could travel before the need for rest became imperative. "There were many Rorn, and they each took one stone. And of them, they made a house for their leader." The leader, as she pictured him, being the most hideous travesty of a thing in semi-human form that the mind could imagine: incredibly old and wrinkled and ugly and gray, his noseless face seamed with cunning, his eyes red rimmed and terrible, his teeth gleaming, white and sharp, like fangs.
"A whole house, except the roof," she went on. "It is there now, and it is gazed at with much admiration by all the Rorn. All this our prisoner told us before we took him, with a rock made fast to him, out over the Place of Darkness. He, too, was very proud of their leader's house."
"Treasure!" I commented to Mercer. "If we could find the city of the Rorn, we might make the trip pay for itself!"
I could sense his wave of amusement.
"I think," he replied, "I'd rather stand it myself. These Rorn don't appeal to me."
It was over half an hour before we were at last free of our diving suits.
The first thing Captain Bonnett said:
"We've got to get to the surface, and that quickly. Our air supply is running damnably low. By the time we blow out the tanks we'll be just about out. And foul air will keep us here until we rot. I'm sorry, sir, but that's the way matters stand."
Mercer, white-faced and ill, stared at him dazedly.
"Air?" he repeated groggily – I knew just how he felt – "We should have lots of air. The specifications – "
"But we're dealing with facts, not specifications, sir," said Captain Bonnett. "Another two hours here and we won't leave ever."
"Then it can't be helped, Captain," muttered Mercer. "We'll go up. And back. For more compressed air. We must remember to plot our course exactly. You kept the record on the way out as I instructed you?"
"Yes, sir," said Captain Bonnett.
"Just a minute, then," said Mercer.
Weakly he made his way forward to the little cubbyhole in which was housed the central station of his thought-telegraph. I didn't even inspect the gleaming maze of apparatus. I merely watched him dully as he plugged in an antenna similar to the one we had left with Imee, and adjusted the things on his head.
His eyes brightened instantly. "She's still wearing her antenna," he said swiftly over his shoulder. "I'll tell her that something's happened; we must leave, but that we will return."
He sat there, frowning intently for a moment, and then dragged the antenna wearily from his head. He touched a switch somewhere, and several softly glowing bulbs turned slowly red and then dark.
"You and I," he groaned, "had better go to bed. We overdid it. She understands, I think. Terribly sorry, terribly disappointed. Some sort of celebration planned, I gather. Captain Bonnett!"
"Yes, sir?"
"You may proceed now as you think best," said Mercer. "We're retiring. Be sure and chart the course back, so we may locate this spot again."
"Yes, sir!" said Captain Bonnett.
When I awoke we were at anchor, our deck barely awash, before the deserted beach of Mercer's estate. Still feeling none too well, Mercer and I made our way to the narrow deck.
Captain Bonnett was waiting for us, spruce in his blue uniform, his shoulders bowed as always.
"Good morning, gentlemen," he offered, smiling crisply. "The open air seems good, doesn't it?"
It did. There was a fresh breeze blowing in from the Atlantic, and I filled my lungs gratefully. I had not realized until that instant just how foul the air below had been.
"Very fine, Captain," said Mercer, nodding. "You have signaled the men on shore to send out a boat to take us off?"
"Yes, sir; I believe they're launching her now."
"And the chart of our course
