We were too busy to talk. Mercer worked frantically in his laboratory, slaving feverishly beside the big hood. I overlooked the tests of the submarine and the loading of the necessary supplies.
The girl we had taken back to her parents, giving her to understand that she was to wait. They went away, but every few hours returned, as though to urge us to greater haste. And at last we were ready, and the girl and her two companions seated themselves on the tiny deck of the Santa Maria, just forward of the conning tower, holding themselves in place by the chains. We had already instructed the girl in her duties: we would move slowly, and she should guide us, by pointing either to the right or the left.
I will confess I gave a last long, lingering look at the shore before the hatch of the conning tower was clamped down. I was not exactly afraid, but I wondered if I would ever step foot on solid land again.
Standing in the conning tower beside Mercer, I watched the sea rise at an angle to meet us, and I dodged instinctively as the first green wave pelted against the thick porthole through which I was looking. An instant later the water closed over the top of the conning tower, and at a gentle angle we nosed towards the bottom of the sea.
An account of the trip itself, perhaps, does not belong in this record. It was not a pleasant adventure in itself, for the Santa Maria, like every undersea craft, I suppose, was close, smelly, and cramped. We proceeded very slowly, for only by so doing could our guide keep her bearings, and how she found the way was a mystery to all of us. We could see but very little, despite the clearness of the water.
It was by no means a sight-seeing trip. For various reasons, Mercer had cut our crew to the minimum. We had two navigating officers, experienced submarine men both, and five sailors, also experienced in undersea work. With such a short crew, Mercer and I were both kept busy.
Bonnett, the captain, was a tall, dark chap, stooped from years in the low, cramped quarters of submarines. Duke, our second-officer, was a youngster hardly out of his 'teens, and as clever as they come. And although both of them, and the crew as well, must have been agog with questions, neither by word nor look did they express their feelings. Mercer had paid for obedience without curiosity, and he got it.
We spent the first night on the bottom, for the simple reason that had we come to the surface, we might have come down into territory unfamiliar to our guide. As soon as the first faint light began to filter down, however, we proceeded, and Mercer and I crowded together into the conning tower.
"We're close," said Mercer. "See how excited they are, all three of them."
The three strange creatures were holding onto the chains and staring over the bulging side of the ship. Every few seconds the girl turned and looked back at us, smiling, her eyes shining with excitement. Suddenly she pointed straight down, and held out her arm in unmistakable gesture. We were to stop.
Mercer conveyed the order instantly to Bonnett at the controls, and all three of our guides dived gracefully off the ship and disappeared into the depths below.
"Let her settle to the bottom, Bonnett," ordered Mercer. "Slowly … slowly…"
Bonnett handled the ship neatly, keeping her nicely trimmed. We came to rest on the bottom in four or five seconds, and as Mercer and I stared out eagerly through the round glass ports of the conning tower, we could see, very dimly, a cluster of dark, rounded projections cropping out from the bed of the ocean. We were only a few yards from the edge of the girl's village.
The scene was exactly as we had pictured it, save that it was not nearly as clear and well lighted. I realized that our eyes were not accustomed to the gloom, as were those of the girl and her people, but I could distinguish the vague outlines of the houses, and the slowly swaying shapes of monstrous growths.
"Well, Taylor," said Mercer, his voice shaking with excitement, "here we are! And here" – peering out through the glass-covered port again – "are her people!"
The whole village was swarming around us. White bodies hovered around us as moths around a light. Faces pressed against the ports and stared in at us with great, amazed eyes.
Then, suddenly the crowd of curious creatures parted, and the girl came darting up with the five ancients she had showed us before. They were evidently the council responsible for the government of the village, or something of the sort, for the other villagers bowed their heads respectfully as they passed.
The girl came close to the port through which I was looking, and gestured earnestly. Her face was tense and anxious, and from time to time she glanced over her shoulder, as though she feared the coming of an enemy.
"Our time's short, I take it, if we are to be of service," said Mercer. "Come on, Taylor; into the diving suits!"
I signaled the girl that we understood, and would hurry. Then I followed Mercer into our tiny stateroom.
"Remember what I've told you," he said, as we slipped into the heavy woolen undergarments we were to wear inside the suits. "You understand how to handle your air, I believe, and you'll have no difficulty getting around in the suit if you'll just remember to go slowly. Your job is to get the whole village to get away when the enemy is sighted. Get them to come this way from the village, towards the ship, understand. The current comes from this direction; the way the vegetation bends shows that. And keep the girl's people away until I signal you to let them return. And remember to take your electric lantern. Don't burn it more than is necessary; the batteries are not large and the bulb draws a lot of current. Ready?"
I was, but I was shaking a little as the men helped me into the mighty armor that was to keep the pressure of several atmospheres from crushing my body. The helmet was the last piece to be donned; when it was screwed in place I stood there like a mummy, almost completely rigid.
Quickly we were put into the air lock, together with a large iron box containing a number of things Mercer needed. Darkness and water rushed in on us. The water closed over my head. I became aware of the soft, continuous popping sounds of the air-bubbles escaping from the relief valve of the head-piece.
For a moment I was dizzy and more than a little nauseated. I could feel the cold sweat pricking my forehead. Then there was a sudden glow of light from before me, and I started walking towards it. I found I could walk now; not easily, but, after I caught the trick of it, without much difficulty. I could move my arms, too, and the interlocking hooks that served me for fingers. When my real fingers closed upon a little cross-bar at the end of the armored arms, and pulled the bars towards me, the steel claws outside came together, like a thumb and two fingers.
In a moment we stood upon the bottom of the ocean. I turned my head inside the helmet, and there, beside me, was the sleek, smooth side of the Santa Maria. On my other side was Mercer, a huge, dim figure in his diving armor. He made an awkward gesture towards his head, and I suddenly remembered something.
Before me, where I could operate it with a thrusting movement of my chin, was a toggle switch. I snapped it over, and heard Mercer's voice: " – n't forget everything I tell him."
"I know it," I said mentally to him. "I was rather rattled. O.K. now, however. Anything I can do?"
"Yes. Help me with this box, and then get the girl to put on the antenna you'll find there. Don't forget the knife and the light."
"Right!" I bent over the box with him, and we both came near falling. We opened the lid, however, and I hooked the knife and the light into their proper places outside my armor. Then, with the antenna for the girl, so that we could establish connections with her, and through her, with the villagers, I moved off.
This antenna was entirely different from the one used in previous experiments. The four cross-members that clasped the head were finer, and at their junction was a flat black circular box, from which rose a black rod some six inches in height, and topped by a black sphere half the size
