Seven cycles it requires before the seventh Galu can complete the seventh danger-infested circle since its first Galu ancestor achieved the state of Galu. For ages before, the ancestors of this first Galu may have developed from a Band-lu or Bo-lu egg without ever once completing the whole circle--that is from a Galu egg, back to a fully developed Galu.
Bradley's head was whirling before he even commenced to grasp the complexities of Caspakian evolution; but as the truth slowly filtered into his understanding--as gradually it became possible for him to visualize the scheme, it appeared simpler. In fact, it seemed even less difficult of comprehension than that with which he was familiar.
For several minutes after An-Tak ceased speaking, his voice having trailed off weakly into silence, neither spoke again.
Then the Galu recommenced his, "Food! Food! There is a way out!"
Bradley tossed him another bit of dried meat, waiting patiently until he had eaten it, this time more slowly.
"What do you mean by saying there is a way out?" he asked.
"He who died here just after I came, told me," replied An-Tak.
"He said there was a way out, that he had discovered it but was too weak to use his knowledge. He was trying to tell me how to find it when he died. Oh, Luata, if he had lived but a moment more!"
"They do not feed you here?" asked Bradley.
"No, they give me water once a day--that is all."
"But how have you lived, then?"
"The lizards and the rats," replied An-Tak. "The lizards are not so bad; but the rats are foul to taste. However, I must eat them or they would eat me, and they are better than nothing; but of late they do not come so often, and I have not had a lizard for a long time. I shall eat though," he mumbled. "I shall eat now, for you cannot remain awake forever." He laughed, a cackling, dry laugh. "When you sleep, An-Tak will eat."
It was horrible. Bradley shuddered. For a long time each sat in silence. The Englishman could guess why the other made no sound--he awaited the moment that sleep should overcome his victim.
In the long silence there was born upon Bradley's ears a faint, monotonous sound as of running water. He listened intently.
It seemed to come from far beneath the floor.
"What is that noise?" he asked. "That sounds like water running through a narrow channel."
"It is the river," replied An-Tak. "Why do you not go to sleep?
It passes directly beneath the Blue Place of Seven Skulls. It runs through the temple grounds, beneath the temple and under the city.
When we die, they will cut off our heads and throw our bodies into the river. At the mouth of the river await many large reptiles.
Thus do they feed. The Wieroos do likewise with their own dead, keeping only the skulls and the wings. Come, let us sleep."
"Do the reptiles come up the river into the city?" asked Bradley.
"The water is too cold--they never leave the warm water of the great pool," replied An-Tak.
"Let us search for the way out," suggested Bradley.
An-Tak shook his head. "I have searched for it all these moons," he said. "If I could not find it, how would you?"
Bradley made no reply but commenced a diligent examination of the walls and floor of the room, pressing over each square foot and tapping with his knuckles. About six feet from the floor he discovered a sleeping-perch near one end of the apartment.
He asked An-Tak about it, but the Galu said that no Weiroo had occupied the place since he had been incarcerated there.
Again and again Bradley went over the floor and walls as high up as he could reach. Finally he swung himself to the perch, that he might examine at least one end of the room all the way to the ceiling.
In the center of the wall close to the top, an area about three feet square gave forth a hollow sound when he rapped upon it.
Bradley felt over every square inch of that area with the tips of his fingers. Near the top he found a small round hole a trifle larger in diameter than his forefinger, which he immediately stuck into it. The panel, if such it was, seemed about an inch thick, and beyond it his finger encountered nothing.
Bradley crooked his finger upon the opposite side of the panel and pulled toward him, steadily but with considerable force.
Suddenly the panel flew inward, nearly precipitating the man to the floor. It was hinged at the bottom, and when lowered the outer edge rested upon the perch, making a little platform parallel with the floor of the room.
Beyond the opening was an utterly dark void. The Englishman leaned through it and reached his arm as far as possible into the blackness but touched nothing. Then he fumbled in his haversack for a match, a few of which remained to him. When he struck it, An-Tak gave a cry of terror. Bradley held the light far into the opening before him and in its flickering rays saw the top of a ladder descending into a black abyss below. How far down it extended he could not guess; but that he should soon know definitely he was positive.
"You have found it! You have found the way out!" screamed An-Tak.
"Oh, Luata! And now I am too weak to go. Take me with you!
Take me with you!"
"Shut up!" admonished Bradley. "You will have the whole flock of birds around our heads in a minute, and neither of us will escape.
Be quiet, and I'll go ahead. If I find a way out, I'll come back and help you, if you'll promise not to try to eat me up again."
"I promise," cried An-Tak. "Oh, Luata! How could you blame me?
I am half crazed of hunger and long confinement and the horror of the lizards and the rats and the constant waiting for death."
"I know," said Bradley simply. "I'm sorry for you, old top.
Keep a stiff upper lip." And he slipped through the opening, found the ladder with his feet, closed the panel behind him, and started downward into the darkness.
Below him rose more and more distinctly the sound of running water.
The air felt damp and cool. He could see nothing of his surroundings and felt nothing but the smooth, worn sides and rungs of the ladder down which he felt his way cautiously lest a broken rung or a misstep should hurl him downward.
