The Governor Vanishes
Far below the surface of San Luz, white-hot rock, flowing like incandescent molasses, forced its way upward under enormous pressure. Sometimes the magma remained quiet for hours, pulsing slightly like a living thing. Then it would melt its way through to a weakness in the earth's structure, creating a new channel for its upward flow.
In one new channel was basaltic rock with a higher moisture content than the magma had encountered before. As the moisture turned instantly to steam, it expanded with sudden violence, and the earth shook with the force of the explosion.
Far above the pocket, Rick Brant felt the earth tremble, and shook his head. The temblors were increasing in frequency, although none had been as violent as that first day's earthquake. The boy looked at Scotty. His pal's face was grim.
The scientists around the worktable had paused, too, as they felt the earth tremble.
Esteben Balgos said quietly, "El Viejo is getting ready. If we are going to act, it must be soon."
"Act?" Connel demanded. "How?"
Balgos shrugged. "That is what we are here to decide."
Rick watched the geologist's face. He was sure that Connel, for reasons unknown, was trying to slow down the project. He was satisfied that the man had stolen both the initial tracings and the dynamite. He also knew that Connel lied. On their return from trailing him to Casa Guevara, the boys had found Connel having a cup of coffee in the dining room and had asked casually where he had gone. He had muttered something about going into Calor for a supply of cigars.
Hartson Brant asked, "What do you make of this series of tracings? My own opinion is that we have found a structural weakness through which the magma will move. But the weakness does not extend far enough upward to give any idea of the channel the magma will take to the surface."
The scientist pointed to a series of blue lines as he spoke. Dr. Williams examined the lines, then took his pencil and began to sketch rapidly on his cross-section drawing of the volcano and the earth under it. Rick watched as the sketch took shape. From the upper lens-shaped magma front Williams was drawing a series of lines that changed direction, moving toward the western side of the island. Then, across the top of the upward-moving lines Williams drew a horizontal line.
"Those upward strokes are the fissures shown by the tracings," he said. "Notice that they stop at the horizontal line. My guess is that the horizontal line represents an unbroken stratum that will probably stop the magma temporarily. We may even have another one of those lens-shaped pools develop."
Big Hobart Zircon poked at the sketch with a huge finger. "Jeff, how far below the surface is this stratum?"
"Slightly over a quarter of a mile, I'd guess. It's hard to be accurate within a few feet. On that side of the mountain the ocean bottom is a few hundred feet below sea level, and I'd say the hard rock is probably a thousand feet below that."
Zircon rubbed his chin thoughtfully. "If we could somehow breach that hard rock and allow room for the magma to flow upward, what would happen?" he inquired.
Esteben Balgos exclaimed excitedly, "Once through the layer of hard rock, the magma would encounter plenty of surface water. Look at Jeff's sketch. Above the hard rock there are many fissures, which must have a high water content. If the magma reaches those, we will have violent eruption through the western side of the mountain, probably right about sea level."
Rick could see instantly what Balgos meant. "Dad, an eruption on the west side would be perfect! The mountain itself would protect Calor and the rest of the island!"
"That's true, Rick," Hartson Brant agreed. "The problem is, how can we possibly create a break in a layer of hard rock so far underground?"
David Riddle answered him. "There's one way. Drive a tunnel down through it."
All eyes looked at him.
"Can it be done?" Julius Weiss demanded.
"Yes. If there's enough time, enough machinery, and enough manpower. But look at the problem. Once the magma starts to move upward through those faults Jeff has drawn, it will move fast. The tunnel would have to be done before the magma started to move. Otherwise, the heat would be too great for men to work, and even if they could work they'd be drilling right into magma."
"This stuff is beyond me," Connel said. "Let me know what you decide, will you?" He turned and walked from the room.
Rick's eyes met Scotty's. The ex-Marine nodded, and in a moment quietly slipped out of the room.
Julius Weiss demanded, "Are you seriously proposing that we drive a tunnel for over a quarter mile, almost straight down, through solid rock?"
Riddle shrugged. "Do you know any other way of releasing the magma safely? I don't."
"Perhaps it could be done," Hartson Brant said thoughtfully. "But, as Dave says, we'd need time, machinery, and manpower. I'm sure we can get the machinery and the manpower from the governor. But do we have time?"
Balgos and Williams looked at each other. They were the experts. It was up to them to say.
"How long, Jeff?" Balgos asked.
"I don't know. If we assume the magma will continue rising at roughly the same rate we've measured during the past few days, I'd guess perhaps two or three weeks. On the other hand, the magma could find weaknesses we haven't detected. We may have only a few days."
"We'll have to try," Hartson Brant stated. "If the governor can give us the entire labor force of the island, and all available earth-moving machinery, we have a chance at least. If we do nothing, there's no chance at all. I think we should pay a visit to the governor right now."
Scotty came back into the room. "Connel's in his room," he reported. "I think he made a telephone call, but I can't be sure without checking with the switchboard. Shall I?"
"It doesn't matter," Rick told him. "We're on our way to see the governor. Connel can't stop things now."
The scientists were already moving through the door and to the jeeps. Within a few moments the small convoy was moving down the mountainside toward Calor and the executive offices.
Inside the cool, white stone building the group waited while Esteben Balgos went to see if the governor was available. He came out of the executive suite with a look of concern on his face.
"The governor is not in," he reported. "His secretary does not know where he is. The secretary's worried. Montoya didn't show up at all this morning and his residence says he left at the usual time. I think we'd better see the lieutenant governor."
Rick started to speak, but thought better of it. Connel had not come with them, and his visit to Guevara could mean nothing.
Jaime Guevara was a tall, thin man with a hawk face and a tiny goatee. Hartson Brant, as spokesman, got to the point right away. He described the reason for their coming, and their findings to date. He stressed the need for fast action. In the governor's absence, he stated, they would need the active support of Señor Guevara. If he would issue orders at once, the scientific group would be happy to organize and supervise the work.
Guevara listened until the scientists had finished, then he smiled. "A strange tale," he said. "It is difficult to believe El Viejo is getting ready to erupt. Surely your imaginations have run away with you."
"We do not depend on imagination," Balgos said curtly. "We depend on scientific investigation. The situation is precisely as Dr. Brant outlined it."
"No doubt," Guevara said soothingly. "But surely you realize I cannot disrupt the economy of the entire island simply to dig a hole. Why, the people would laugh their heads off. No, señores, I am helpless. You had better see the governor."
"The governor isn't here and there is no time to lose," Hartson Brant said flatly. "You must act immediately if the island is to be saved. The lives of your people are in your own hands."
"Perhaps the governor will return soon," Guevara said. "He will doubtless believe your story and take action. I regret that I cannot. And now, if you will excuse me?"
"Then you will not move even to save the island?"
"I do not believe the island is in danger, Dr. Brant," Guevara said coldly. "Convince the governor—if you can find him. Meanwhile, have the favor to cease bothering me with your silly tales!"
