"I had forgotten," said Han Du, "that you are not of Eurobus. Perhaps you have no such trees as these in your world."
"We certainly have not," I assured him. "A few that eat insects, perhaps, like Venus's-flytrap; but no maneaters."
"You must always be on your guard when in one of our forests," he warned me. "These trees are living, carnivorous animals. They have a nervous system and a brain, and it is generally believed that they have a language and talk with one another."
Just then a hideous scream broke from above us. I looked up, expecting to see some strange, Jupiterian beast above me, but there was nothing but the writhing limbs and the staring eyes of the great blossoms of the man-trees.
Han Du laughed. "Their nervous systems are of a low order," he said, "and their reactions correspondingly slow and sluggish. It took all this time for the pain of my sword cut to reach the brain of the blossom to which that limb belongs."
"A man's life would never be safe for a moment in such a forest," I commented.
"One has to be constantly on guard," admitted Han Du. "If you ever have to sleep out in the woods, build a smudge. The blossoms don't like smoke. They close up, and then they cannot see to attack you. But be sure that you don't oversleep your smudge."
Vegetable life on Jupiter, practically devoid of sunlight, has developed along entirely different lines from that on earth. Nearly all of it has some animal attributes and nearly all of it is carnivorous, the smaller plants devouring insects, the larger, in turn, depending upon the larger animals for sustenance on up to the maneaters such as I had encountered and those which Han Du said caught and devoured even the hugest animals that exist upon this strange planet.
We posted a couple of guards, who also kept smudges burning; and the rest of us lay down to sleep. One of the men had a chronometer, and this was used to inform the men on guard when to awaken their reliefs. In this way, we all took turns watching and sleeping.
When all had slept, the smudges were allowed to burn more brightly, the men cut limbs from the living trees, sliced them and roasted them. They tasted much like veal. Then we talked over our plans for the future. It was decided that we should split up into parties of two or three and scatter; so that some of us at least might have a chance to escape recapture. They said that the Morgors would hunt us down for a long time. I felt that we would be much safer remaining together, as we were ten undefeatable sword-arms; but as the countries from which my companions came were widely scattered; and, as naturally, each wished if possible to return to his own home, it was necessary that we separate.
It chanced that Han Du's country lay in the general direction of Zanor, as did Pho Lar's; so we three bid goodby to the others and left them. How I was to reach faraway Zanor on a planet of twenty-three billion square miles of area, I was at some loss to conceive. So was Han Du. He told me that I would be welcome in his country — if we were fortunate enough to reach it; but I assured him that I should never cease to search for Zanor and my mate.
In this world without night, it was difficult to keep account of time; but it seemed to me that we must have traveled for months. Pho Lar remained with us for a great deal of the time, but finally he had to turn away in the direction of his own country. We were sorry to lose him, as he had developed into a splendid companion; and we should miss his sword, too.
We had met no men, but had had several encounters with wild beasts — creatures of hideous, unearthly appearance, both powerful and voracious. I soon realized the inadequacy of our swords as a sole means of defense; so we fashioned spears of a bamboolike growth that seemed wholly vegetable. I also taught Han Du and Pho Lar how to make bows and arrows and to use them. We found them of great advantage in our hunting of smaller animals and birds for food. In the forests, we subsisted almost wholly on the meat of the man-tree.
At last Han Du and I came within sight of an ocean. "We are home," he said. "My city lies close beside the sea." I saw no city.
We had come down out of some low hills, and were walking across a narrow coastal plain. Han Du was several yards to my right, when I suddenly bumped into something solid — solid as a brick wall; but there was nothing there! The sudden collision had caused me to step back. I stretched out my hands, and felt what seemed to be a solid wall barring my way, yet only a level expanse of bare ground, but the ground was not entirely bare. It was dotted, here and there, with strange plants — a simple, leafless stock a foot or two tall bearing a single fuzzy blossom at its top.
I looked around for Han Du. He had disappeared! He had just vanished like a punctured soap bubble. All up and down the shore there was no place into which he could have vanished, nothing behind which he would have hidden, no hole in the ground into which he might have darted. I was baffled. I scratched my head in perplexity, as I started on again toward the beach only to once more bump into the wall that was not there.
I put my hands against the invisible wall and followed it. It curved away from me. Foot by foot, I pursued my tantalizing investigation. After a while I was back right where I had started from. It seemed that I had run into an invisible tower of solid air. I started off in a new direction toward the beach, avoiding the obstacle which had obstructed my way. After a dozen paces I ran into another; then I gave up — at least temporarily.
Presently I called Han Du's Dame aloud, and almost instantly he appeared a short distance from me. "What kind of a game is this?" I demanded. "I bump into a wall of solid air and when I look for you, you are not anywhere, you have disappeared."
Han Du laughed. "I keep forgetting that you are a stranger in this world," he said. "We have come to the city in which I live. I just stepped into my home to greet my family. That is why you could not see me." As he spoke, a woman appeared beside him, and a little child. They seemed to materialize out of thin air. Had I come to a land of disembodied spirits who had the power to materialize? I could scarcely believe it, as there was nothing ghostly nor ethereal about Han Du.
"This is O Ala, my mate," said Han Du. "O Ala, this is John Carter, Prince of Helium. To him we owe my escape from the Morgors."
O Ala extended her hand to me. It was a firm, warm hand of flesh and blood. "Welcome, John Carter," she said. "All that we have is yours."
It was a sweet gesture of hospitality; but as I looked around, I could not see that they had anything. "Where is the city?" I asked.
They both laughed. "Come with us," said O Ala. She led the way, apparently around an invisible corner; and there, before me, I saw an open doorway in thin air. Through the doorway, I could see the interior of a room. "Come in," invited O Ala, and I followed her into a commodius, circular apartment. Han Du followed and closed the door. The roof of the apartment was a dome perhaps twenty feet high at its center. It was divided into four rooms by sliding hangings which could be closed or drawn back against the wall.
"Why couldn't I see the house from the outside?" I asked.
"It is plastered on the outside with sands of invisibility which we find in great quantities along the beach," explained Han Du. "It is about our only protection against the Morgors. Every house in the city is thus protected, a little over five hundred of them."
So I had walked into a city of five hundred houses and seen only an expanse of open beach beside a restless sea. "But where are the people?" I asked. "Are they, too, invisible?"
"Those who are not away, hunting or fishing, are in their homes," explained O Ala. "We do not venture out any more than is necessary, lest Morgors be cruising around in their invisible ships and see us; thus discovering our city."
"If any of us should be thus caught out," said Han Du, "he must run away from the city as fast as he can, for if he entered a house, the Morgors would immediately know that there was a city here. It is the sacrifice that each of us is in honor bound to make for the safety of all, for he who runs is almost invariably caught and carried away, unless he chooses to fight and die."
"Tell me," I said to Han Du, "how in the world you found your house, when you could not see it or any other house."
"You noticed the umpalla plants growing throughout the city?" he asked.
"I noticed some plants, but I saw no city."
They both laughed again. "We are so accustomed to it that it does not seem at all strange to us," said O Ala, "but I can understand that it might prove very confusing to a stranger. You see, each plant marks the location of a house. By long experience, each of us has learned the exact location of every house in the city in relation to every other house."
I remained for what may have been five or six days of earth time in the home of Han Du and O Ala. I met many of their friends, all of whom were gracious and helpful to me in every way that they could be. I was furnished with maps of considerable areas of the planet, parts of which, I was told, were still unexplored even by the Morgors. Of greatest value to me was the fact that Zanor appeared on one of the maps, which also showed that a vast ocean lay between me and the country in which I believed Dejah Thoris to be. How I was to cross this ocean neither I nor my new found friends could offer a suggestion, other than the rather mad scheme I envisioned of building a sail boat and trusting myself to the mad caprices of an unknown sea perhaps swarming with dangerous reptiles. But this I at last decided was the only hope I had for being again reunited with my princess.
There was a forest several miles along the coast from the city, where I might hope to find trees suitable for the construction of my craft. My friends tried their best to dissuade me; but when they found that I was determined to carry out my plan, they loaned me tools; and a dozen of them volunteered to accompany me to the forest and help me build my boat.
At last all was in readiness; and, accompanied by my volunteer helpers, I stepped from the house of Han Du to start the short march to the forest.
Scarcely were we in the open when one of my companions cried, "Morgors!" Whereupon the Savators scattered in all directions away from their city.
"Run, John Carter!" shouted Han Du, but I did not run.
A few yards distant, I saw the open doorway in the side of an invisible ship; and I saw six or seven Morgors emerge from it. Two rushed toward me; the others scattered in pursuit of the Savators. In that instant a new plan flashed across my mind. Hope, almost extinct, leaped to life again.
I whipped my sword from its scabbard and leaped forward to meet the first of the oncoming Morgors, thanking God that there were only two of them, as delay might easily wreck my hopes. There was no finesse in my attack: it was stark, brutal murder; but my conscience did not bother me as I drew my sword from the heart of the first Morgor and faced the second.
The second fellow gave me a little more trouble, as he had been forewarned by the fate of his companion; and, too, he presently recognized me. That made him doubly wary. He commenced to howl to the others, who were pursuing the Savators, to come back and help him, bellowing that here was the creature from Garobus who had led the slaughter at the graduating exercises. From the corner of an eye, I saw that two of them had heard and were returning, I must hurry!
The fellow now fought wholly on the defensive in order to gain time for the others to join him. I had no mind to permit this, and I pressed him hard, often laying myself wide open — a great swordsmen could have killed me easily. At last I reached him with a mighty cut that almost severed his head from his body; then, with only a quick glance behind me to see how close the others were, I leaped toward the open doorway of the otherwise invisible ship, a Morgor close upon my heels.
With naked blade still in my hand, I sprang aboard and closed the door behind me; then I wheeled to face whatever of their fellows had been left aboard to guard the craft. The fools had left no one. I had the ship all to myself; and as I ran to the controls I heard the Morgors beating upon the door, angrily demanding that I open it. They must have taken me for a fool, too.
A moment later the ship rose into the air, and I was away upon one of the strangest adventures of my life — navigating an unknown planet in an invisible craft. And I had much to learn about navigation on Jupiter. By watching Vorion, I had learned how to start and stop a Morgor ship, how to gain or lose altitude, and how to cloak the ship in invisibility; but the instruments upon the panel before me were all entirely meaningless to me. The hieroglyphs of the Morgors were quite unintelligible. I had to work it all out for myself.
Opening all the ports, I had a clear field of vision. I could see the shore I had just left, and I knew the direction of the coast line. Han Du had explained this to me. It ran due north and south at that point. The ocean lay to the west of it. I found an instrument which might easily have been a compass; when I altered the course of the ship, I saw that it was a compass. I now had my bearings as closely as it was possible for me to get them. I consulted my map and discovered that Zanor lay almost exactly southeast; so out across that vast expanse of ocean I turned the prow of my ship.
I was free. I had escaped the Morgors unharmed. In Zanor, Dejah Thoris was safe among friends. That I should soon be with her, I had no doubt. We had experienced another amazing adventure. Soon we should be reunited. I had not the slightest doubt of my ability to find Zanor. Perhaps it is because I am always so sure of myself that I so often accomplish the seemingly impossible.
How long I was in crossing that dismal ocean, I do not know. With Jupiter whirling on its axis nearly three times as fast as earth, and with no sun, moon, nor stars, I could not measure time.
I saw no ship upon that entire vast expanse of water, but I did see life — plenty of it. And I saw terrific storms that buffeted my craft, tossing it about like a feather. But that was nothing compared with what I saw below me as the storms at the height of their fury lashed the surface of the waters. I realized then how suicidal would have been my attempt to cross that terrible ocean in the frail craft that I had planned to build. I saw waves that must have measured two hundred feet from trough to crest — waves that hurled the mighty monsters of the deep as though they had been tiny minnows. No ship could have lived in such seas. I realized then why I saw no shipping on this great Jupiterian ocean.
But at last I sighted land ahead — and what land! Zan Dar had told me of the mighty mountains of Zanor rearing their forested heads twenty miles above the level of the sea, and it was such mountains that lay ahead of me. If I had reckoned accurately, this should be Zanor; and these breath-taking mountains assured me that I had not gone wrong.
I knew from Zan Dar's explanation, just where to search for the stamping grounds of his tribe — a wild mountain tribe of fighting men. They lay in a land of meadows and ravines on the east slope of the highest mountain and at an altitude of only about ten miles, or about half way to the summit. Here the air is only slightly thinner than at sea level, as the cloud envelope retains the atmosphere of Jupiter as though it were held in a bag, permitting none of it to escape, while the rapid revolution of the planet tends to throw the atmosphere far up from the surface.
Most fortunate was I in coming upon the village of Zan Dar with little or no difficulty. Entirely invisible, I hovered above it, dropping down slowly. I knew that the moment they saw a Morgor ship, they would disappear into the forests that surrounded the village, waiting there to rush out upon any Morgors who might be foolish enough to leave the ship after landing.
There were people in plain view of me in the village as I dropped to within fifty feet of the ground. I stopped the ship and hung there, then I demagnetized the hull; and, as the ship became instantly visible, I leaped to the door and pushed it open; so that they could see that I was no Morgor. I waved to them and shouted that I was a friend of Zan Dar, and asked permission to land.
They called to me to do so, and I brought the ship slowly toward the ground. My lonely voyage was over. I had surmounted seemingly unsurmountable obstacles and I had reached my goal. Soon my incomparable Dejah Thoris would be again in my arms.
