At last, U-Val saw the land ahead. "You were right," he admitted grudgingly. "There is land ahead; and it is Ruva, but I don't understand how you could have seen it so much sooner than I."
"That is quite easily explained," I replied.
"How?" he demanded.
"I can see farther than you can."
"Nonsense!" he snapped. "No one can see any farther than I."
What was the use of arguing with a mind like that? Anyway, I had something more important to discuss with him. I fitted an arrow to my bow.
"Why are you doing that?" he demanded, glancing quickly around. "There is nothing to shoot."
"There is you," I said.
For a moment he didn't quite grasp the implication. When he did, he reached for a spear.
"Don't touch it!" I commanded, "or I'll put an arrow through your heart."
He let his hand drop to his side. "You wouldn't dare," he said without much conviction.
"And why not? I can see land ahead, and I can reach it without any help from you."
"It would do you no good. My people would kill you."
"Perhaps, and perhaps not," I countered. "I should tell them that I am your friend and that you sent me to Ruva to get a rescue party to come to the mainland to save you because you are being held a prisoner. If they are all as stupid as you, they will believe me; and they will take me back to the mainland to guide them to you. When we reach there, I shall pretend to go alone to spy upon the tribe that captured you; and I shall not come back. That is the last they will ever see of me."
"But you wouldn't kill me, David," he plead. "We have been friends. We fought side by side. When I could have killed you, I spared your life."
"But you kicked me in the belly when I was bound and helpless," I reminded him.
"I am sorry," he wailed; "and, anyway, I didn't kick you very hard. Oh, please don't kill me, David. Let me live, and I will do everything I can for you."
"Well, I am not going to kill you, because for some reason I couldn't bring myself to kill a helpless man in cold blood if there were any way to avoid it without jeopardizing my own life; so I will make you a proposition. If I spare your life, you must promise to take me among your people, not as a slave but as a friend whom you will protect from other members of your tribe; and at the first opportunity you will help me return to the mainland."
"I promise," he said, eagerly. A little too eagerly, I thought. I should have killed him then; and I knew it, but I couldn't bring myself to the point of murder.
"Very well, see that you keep your promise," I said, laying aside my bow.
As we neared the floating island of Ruva it appeared as low, level land, thickly grown with trees. It floated low in the water, its upper surface scarcely more than five feet above the waterline; and nowhere could I detect any sign of hills. The coast directly in view was irregular, being broken by small inlets or bays; and into one of these U-Val steered our craft. I took down our sail, and he paddled to shore.
It was good to feel ground beneath my feet again and to be able to stretch and move about.
U-Val made the canoe fast to a tree; and then, cupping his hands, voiced a high, piercing call. Then he listened. Presently, from far away came an answering cry.
"Come!" said U-Val. "They are by the fishing hole;" and he started off toward the interior along a well defined trail that wound through the forest.
The trees, of no great size, grow close together. They are of a species I had never seen before, as soft and spongy as some varieties of cactus but without spines or thorns. It is these trees which really not only make The Floating Islands, of which Ruva is one, but also make them a fit abode for human beings. The roots of the trees, closely interlaced, keep the islands from disintegrating and form a natural basket which holds the soil in which the vegetation grows. The trees also furnish a portion of the food supply of the islanders and all of their supply of fresh water, which they can obtain at any time by either tapping the bole of a tree or cutting off a limb. The tender young shoots are edible, and the fruit of the tree is one of the principal staples of food. There is little other vegetation on the island, and little need for other. Some long grass grows among the trees and there are several parasitic vines which sport gorgeous blooms. A few varieties of birds live on the island, affording the inhabitants a little variety in diet from the staple tree-food and fish, as they eat both their flesh and their eggs.
We had walked about a mile when we came to an area that had been partially cleared. A few scattered trees had been left, probably for the purpose of holding the soil together with live roots. In the center of the clearing a hole had been cut, possibly a hundred feet in diameter, forming a small pool. Some fifty people of both sexes and all ages were gathered in the clearing. Several of them stood beside the pool with their spears poised, waiting for a fish to swim within striking distance. The fishes must have learned from experience what would happen to them if they swam too close to the shoreline, for the center of the pool, out of range of a spear-thrust, fairly teemed with fish. Occasionally a foolish or unwary individual would swim within range, when instantly he would be impaled upon a barbed spearhead. The skill of these spearmen was most uncanny-they never missed; but because of the wariness of the fish, their catches were few.
As U-Val and I entered the clearing, the first man to notice us said, "U-Val has returned!" Then every eye was turned upon us; but there was no enthusiastic greeting for the returned prodigal.
A big fellow came toward us. "You have brought back a slave," he said. It was not a question, merely a statement of fact.
"I am not a slave," I rejoined. "U-Val and I were imprisoned together. We fought together. We escaped together; and so, in honor, U-Val could not make me his slave."
"If you are not a slave, you are an enemy," replied the man; "and enemies we kill."
"I would come here as a friend," I said. "There is no reason why we should be enemies. As a matter of fact, I can be a very valuable friend."
"How?" he demanded.
"I can show you how to build canoes that will travel without paddling," I replied; "and I can show you how to catch the fish in the middle of the pool, which you are unable to reach with your spears."
"I don't believe you can do either of those things," he said, "for if they could have been done, we could have done them. We know all there is to know about canoes and fishing. No one can teach us anything new."
I turned to U-Val. "Didn't I make your canoe go without paddling?" I demanded.
U-Val nodded. "Yes, it went even faster than I could paddle; but I can show them how to do that."
"Yes," I replied; "but you can only show them how it is done when the wind is directly behind you; but I can show them how to build canoes in which they can travel no matter in what direction the wind is blowing. That, you cannot do."
"Is that true, U-Val?" asked the man.
"Yes, Ro-Tai, it is true," replied U-Val.
"And can he catch fish from the middle of the pool?"
"That, I do not know."
Ro-Tai turned to me. "If you can do these things at all," he said, "you can do them just as well if you are a slave."
"But I won't do them if I am a slave. I won't show you how to, either."
"You will, or we'll kill you," snapped Ro-Tai.
"If you kill me, you'll never learn how to do it," I reminded him.
While we had been talking, a number of men had congregated about us, interested listeners. Now one of them spoke up. "We should accept this man as a friend, Ro-Tai," he said, "on condition that he teaches us these things."
"Yes," said another, "Ul-Van has spoken words of wisdom. I do not believe that the stranger can do these things; and, if he cannot, we can either make him a slave or kill him."
