"Certainly not," Hartson Brant replied. "First, we must develop more data. Dr. Balgos had said that his conclusions are based on intuition, and not facts. I, for one, trust his intuition. But we must know the exact situation before we can even begin to study the possibilities of doing something." Tony Briotti objected. "Even with a study, what can be done? I'm not a physical scientist, so this is outside of my field. But I've never heard of anyone even attempting to change the direction of a lava flow, much less control an eruption." Dr. Balgos spread his hands expressively. "In mythology, Vulcan was the blacksmith, the god of fire and volcanoes. We have grown too wise to believe in myths, but we do believe in the scientific method. I come to you, as some of its most famous practitioners. If anything can be done--and I do not know if it can--then you are the scientific team that can do it. If you can do nothing, then San Luz will die, violently, under Vulcan's hammer!" CHAPTER II San Luz Rick Brant awoke slowly. For a moment he lay with eyes closed while he tried to identify the strange odor that smote his nostrils. It was a noxious combination of medicine, burned matches, and ancient eggs. Then he remembered, and sat bolt upright in bed. San Luz! The smell of the hot springs burned his nose even through the air-conditioning system. It must be awful outside, he thought. It had been bad enough last night. He looked over to the other bed in the luxurious room and saw Scotty, wrapped like a cocoon in sheet and blanket. For a moment he was tempted to heave a pillow at the ex-Marine, then reconsidered. Scotty needed sleep. Let him wake up naturally. Rick lay back on his pillow and closed his eyes. He could do with a little more shut-eye himself. So much had happened in the past few days that he was still spinning from the speed of it. The arrival of Dr. Esteben Balgos had upset Spindrift more thoroughly than anything else Rick could remember. He and Scotty had sat through hours of argument and heated debate. Jan and Barby had given up when the scientific arguments got far beyond their ability to understand. Rick hadn't understood much either, but he had stuck it out to the end. The conclusion was that probably nothing could be done. There was simply no way to check the eruption of a volcano. If El Viejo was going to blow its top, well . . . that was that. But the Spindrift Scientific Foundation was not known for its eagerness to drop seemingly insoluble problems, so the staff had agreed that a study should be made, at the very least. Hartson Brant had chosen Hobart Zircon and Julius Weiss to work with him, then he had persuaded an old friend, Dr. Jeffrey Williams, to drop his work for a short time and join the party. Dr. Williams was a noted seismologist. From the U. S. Geological Survey, Hartson Brant had borrowed Dr. David Riddle, a geologist with considerable experience in volcanology.
