The plain had begun sinking in along their direction of travel. After the first hour, they were in a shallow depression four feet deep, almost a mile wide, and extending ahead and behind as far as they could see. By the end of the second hour, the edges of the depression were just above their heads. When they stopped to rest, they were at the bottom of a trough twelve feet high but now only half a mile wide.
Its walls were steep though not so much they were unclimbable. Not yet, anyway.
What Kickaha found ominous was that all the animal life, and most of the vegetable life, had gotten out of the depression.
"I think we'd better get our tails up onto the plain," he said. "I have a funny feeling about staying here."
Urthona said, "That means walking just that much farther. I'm so tired I can hardly take another step."
"Stay here then," the redhead said. He stood up. "Come on, Anana."
At that moment he felt wetness cover his feet. The others, exclaiming, scrambled up and stared around. Water, looking black in the light, was flowing over the bottom. In the short time after they'd become aware of it, it had risen to their ankles.
"Oh, oh!" Kickaha said. "There's an opening to the lake now! Run like hell, everybody!"
The nearest bank was an eighth of a mile, six hundred and sixty feet away. Kickaha left the antelope leg behind him. The quiver and bow slung over his shoulder, the strap of the instrument case over the other, he ran for the bank. The others passed him, but Anana, once more, grabbed his hand to help him. By the time they had gotten halfway to safety, the stream was up to their knees. This slowed them down, but they slogged through. And then Kickaha, glancing to his left, saw a wall of water racing toward them, its blackish front twice as high as he.
Urthona was the first to reach the top of the bank. He got down on his knees and grabbed one of McKay's hands and pulled him on up. Red Ore grabbed at the black's ankle but missed. He slid back down the slope, then scrambled back up. McKay started to reach down to help, but Urthona spoke to him, and he withdrew his hand.
Nevertheless, Ore climbed over the edge by himself. The water was now up to the waists of Kickaha and Anana. They got to the bank, where she let go of his hand. He slipped and fell back but was up at once. By now he could feel the ground trembling under his feet, sonic forerunners of the vast oncoming mass of water.
He grabbed Anana's legs, boosted her on up, and then began climbing after her. She grabbed his left wrist and pulled. His other hand clutched the grass on the lip of the bank, and he came on up. The other three were standing near her, watching them keenly. He cursed them because they'd not tried to help.
Ore shrugged. Urthona grinned. Suddenly, Urthona ran at Ore and pushed him. Ore screamed and fell sideways. McKay deftly pulled the beamer from Anana's belt. At the same time, he pushed with the flat of his hand against her back. Shrieking, she, too, went into the stream.
Urthona whirled and said, "The Horn of Sham-barimen! Give it to me!"
Kickaha was stunned at the sudden sequence of events. He had expected treachery, but not so soon.
"To hell with you!" he said. He had no time to look for Anana, though he could hear her nearby. She was yelling and, though he couldn't see her, must be climbing up the bank. There wasn't a sound from Red Ore.
He lifted the shoulder strap of the instrument case holding the horn and slipped it down his arm. Urthona grinned again, but he stopped when Kickaha held the case over the water.
"Get Anana up here! Quickly! Or I drop this!"
"Shoot him, McKay!" Urthona yelled.
"Hell, man, you didn't tell me how to operate this thing!" McKay said.
"You utter imbecile!"
Urthona leaped to grab the weapon from the black man. Kickaha swung the instrument case with his left hand behind him and dropped it. Hopefully, Anana would catch it. He dived toward McKay, who, though he didn't know how to fire the beamer, was quick enough to use it as a club. Its barrel struck Kickaha on the top of his head, and his face smacked into the ground.
Half-stunned, he lay for a few seconds, trying to get his legs and arms to moving. Even in his condition, he felt the earth shaking under him. A roaring surged around him, though he did not know if that was the flood or the result of the blow.
It didn't matter. Something hit his jaw as he began to get up. The next he knew, he was in the water.
The coldness brought him somewhat out of his daze. But he was lifted up, then down, totally immersed, fighting for breath, trying to swim. Something smashed into him-the bottom of the channel, he realized dimly-and then he was raised again. Tumbling over and over, not knowing which way was up or down, and incapable of doing anything about it if he had known, he was carried along. Once more he was brought hard against the bottom. This time he was rolled along. When he thought that he could no longer hold his breath- his head roared, his lungs ached for air, his mouth desperately wanted to open-he was shot upward.
For a moment his head cleared the surface, and he sucked in air. Then he was plunged downward and something struck his head.
CHAPTER SIX
KICKAHA AWOKE ON his back. The sky was beginning to take on horizontal bands of alternating dark-red and fiery-red. It was "dawn."
He was lying in water which rose halfway up his body. He rolled over and got to all-fours. His head hurt abominably, and his ribs felt as if he'd gone twelve rounds in a boxing match. He stood up, weaving somewhat, and looked around. He was on shore, of course. The roaring wave had carried him up and over the end of the channel and then retreated, leaving him here with other bodies. These were a dozen or so animals that had not gotten out of the channel in time.
Nearby was a boulder, a round-shaped granite rock the size of a house. It reminded him of the one in the clearing in Anana's world. In this world there were no rock strata such as on Earth. But here were any number of small stones and occasionally boulders, courtesy of the Lord of the lavalite planet, Urthona.
He remembered Anana's speculation that some of these could conceal "gates." With the proper verbal or tactile code, these might be opened to give entrance into Urthona's castle somewhere on this world. Or to other pocket universes. Urthona, of course, would neither verify nor deny this speculation.
If he had the Horn of Shambarimen, he could sound the sequence of seven notes to determine if the rock did contain a gate. He didn't have it. It was either lost in the flood or Anana had gotten up the bank with it. If the latter had happened, Urthona now had the Horn.
A mile beyond the boulder was a mountain. It was conical, the side nearest him lower than the other, revealing a hollow. It would not be a volcano, since these did not exist here. At the moment, it did not seem to be changing shape.
There were tall hills in the distance, all lining the channel. Most of the plain was gone, which meant that the mutations had taken place at an accelerating speed.
His bow and quiver were gone, torn from him while he was being scraped against the channel bottom. He still had his belt and hunting knife, however.
His shirt was missing. The undershirt was only a rag. His trousers had holes and rips, and his shoes had departed.
Woozily, he went to the edge of the water and searched for other bodies. He found none. That was good, since it gave him hope, however slight, that Anana had survived. It wasn't likely, but if he could survive, she might.
Though he felt better, he was in no mood to whistle while he worked. He cut a leg off an antelope and skinned it. Hordes of large black green-headed flies settled on the carcass and him and began working. The bite of one fly was endurable, but a hundred at once made him feel as if he were being sandpapered all over. However, as long as he kept moving he wasn't covered by them. Every time he moved an arm or turned his head or shifted his position, he was relieved of their attack. But they zoomed back at once and began crawling, buzzing, and biting.
