"I would like nothing better," the big pilot answered. In a way, this was his dream too, though up until now it had always been a secret, hidden, impossible-to-accomplish thing. His hand went out to Rozeno. Deep inside of him, the glow grew to greater heights. Only one other thing was needed to make this glow a really perfect feeling, Effra, who had found this island and had tried to tell him about it. But Effra was gone. They moved on to a big room where some of the scientific equipment of the vanished race still functioned. Set in a sunken pool ten feet in diameter in the center of the room was a circle of what looked like mercury. Leading up from it were heavy bus bars of some unknown metal. The bus bars came together and marched across the room to a control panel, one of the strangest control panels Parker had ever seen. The meters were graduated in colors. In front of the chair where the operator sat was a keyboard like that of a vast pipe organ. How much training would an operator need to operate this keyboard? Directly in front of the operator's seat was a square panel that looked like a television screen. * * * * * Set in niches where the right hand of the operator could reach them easily were statuettes of birds, animals, reptiles. Made of some metal, they were perfect representations. Parker saw a condor, a bald-headed eagle, a humming-bird, a cougar, a jaguar, an alligator. His eyes went back to the pool in the center of the room. "It is generating power," Rozeno said. "As it turns, it creates some force, some energy. I do not understand this energy. No one now alive understands it. Understanding is one of the things I hope your scientists may achieve--come away, Ulnar." The last was spoken as the Indian strayed near the operator's seat. Ulnar grunted impatiently. There was something about that seat that lured him. But he came away. They went into another room, leaving behind them the pool of mercury that turned slowly, like a miniature earth on some axis of its own. Parker took one look at the contents of this room, and gasped. The crown jewels of England were no greater than these! Here were crowns of pounded yellow gold; here were gargoyle masks made of the same yellow metal; masks that sparkled with gems. Here, lying on the rock shelves, were ingots of what looked to be solid gold, each one heavy enough to be a full load for a grown man. Ulnar was examining a gargoyle mask. He touched a gold bar, his old withered fingers seeming to savor the feel of it. Rozeno smiled gently. "Ulnar treasures these things, they were put in his charge a very long time ago. He has been faithful to his trust." "But--" Parker whispered. "This is a part of Montezuma's treasure, a part that Cortez did not get. There is as much of it here as 400 men could carry away. Ulnar was one of Montezuma's most trusted sub-chiefs. He brought the treasure here, to keep it for his Chieftan."
