"No? He is getting away with it, Senor Rick. We have a dozen policemen; he has the army. He also has his own men, at key points. So what can we do? We haven't enough force to fight. Besides, there is no time. We can't arm the people because we have neither weapons nor time."

"But what can we do?" Scotty demanded.

"I do not know. At least we can continue our efforts to get the people off the island. Without the ability to make scientific readings, we cannot know how much time is left, so we must hurry. We will do the best we can. After that--well, you had a Spanish song in America that says it well. You recall the t.i.tle? '_Que sera sera._'"

Rick remembered. An expression of fatalism. What will be, will be.

CHAPTER XVI

The Brant Approach

The magma drove upward, melting its way through the fractured rock of the channels under the western side of the island. Now and then it struck rock with a higher water content, and the island shuddered under a new explosion as the steam expanded.

Rick felt the bed shake under him and sat upright. A new day had dawned, and there was much to do. He and Scotty had volunteered to help Captain Ricardo Montoya plan the evacuation of the island, and the youthful officer had accepted with pleasure. He had agreed to meet them for breakfast.

The scientists had worked late, trying to extrapolate their data into some kind of prediction. Rick and Scotty, tired after an exhausting day, had gone to bed while the light still burned in Hartson Brant's room.

Scotty awoke as Rick's feet hit the floor. "I'm getting used to these little earthquakes," he said. "Don't know if I'll be able to sleep on steady ground after this."

"The ground is going to get unsteadier," Rick reminded. "Until--boom!"

"I'm not forgetting," Scotty said grimly. "Let's get dressed and eat.

I'm famished."

"It's ham and eggs for me," Rick told him. "If I had to watch milk slosh around in a cereal bowl I'd get seasick."

The boys dressed rapidly and hurried down to the hotel coffee shop. They were just in time. Ricardo Montoya walked in just as they were seated.

The officer joined them. Rick noted that his face was drawn and tired, and thought Montoya had probably been up a good part of the night.

"How's the evacuation going?" Rick asked.

Montoya shook his head. "Poorly. My uncle's radio broadcast continued all night and through the morning hours. A few families have come to the harbor, and the stevedores are organized now to get them aboard ship. A few fishing boats have come, with fishermen's families, but there is no big exodus."

"Don't they realize the danger?" Scotty exclaimed.

"Perhaps. You must understand my people. They have lived with earthquakes all their lives. Not so often, perhaps, but these temblors are not unusual. What is there to be excited about? Who believes El Viejo will explode? It never has, so it never will."

Rick thought it over. "Maybe not enough are hearing the broadcasts."

"That is possible. I have put volunteers to work going from house to house, asking people to turn on their radios to hear the governor, and also to explain the urgency. But it will take a long time, even in Calor."

"If we only had the troops," Rick said thoughtfully. "Trained manpower is what's needed for a job like this."

"True. And I think if my uncle could only talk to the troops they would believe him. But he cannot reach them. Guevara's peons would never let him by."

The hotel loud-speaker system drowned out his last words as a soft feminine voice paged someone in Spanish.

"If only the troops could listen to the radio," Rick commented. "Perhaps they'd believe him and turn on Guevara."

"Perhaps. But soldiers cannot afford radios, and they are away from their barracks now. There is no way for my uncle's voice to reach them."

There had to be, Rick thought. There had to be some way. The loud-speaker sounded again, paging a Senor Alvarez. Rick sat bolt upright. Why not use a loud-speaker?

"Listen," he said excitedly. "If the government radio station has a loud-speaker system, or can make one, we can put it in my plane. I can fly the governor over the troops and he can talk to them direct. My plane can go slowly enough, and low enough for that!"

"How about power supply?" Scotty asked.

"There must be an inverter on the island somewhere. We can use automobile batteries, and the inverter will give us 110 AC for a while, until the batteries run down. Just twenty minutes of power would be enough and we can get that with enough batteries!"

Scotty chuckled. "The Brant approach," he said. "There always is one.

How about it, Captain?"

"We will try," Montoya said decisively. "You have not eaten?... Then do so, while I make a phone call to the radio station. I have had coffee and rolls, and perhaps there will be time to join you for more breakfast while the radio engineers get the equipment together."

The boys were just finishing ham and eggs when Montoya returned. There was a broad smile on his tired face.

"The engineers say it can be done. They have a portable loud-speaker system, and there is an inverter, as you call it, at the transmitter.

What is this inverter?"

"It's an electric generator," Rick explained. "Battery current turns it, and it produces 110-volt alternating current. But inverters aren't very efficient, and they take a lot of battery current. That's why we'll need as many batteries as we can carry."

"The chief radio engineer said he understood exactly what was needed. He will gather the materials and meet us at the airport. Now, I think we have time for coffee, and perhaps I can follow your example with ham and eggs. It will take an hour for the equipment to be ready. Also, I called my uncle. He will be waiting for our call."

"Did you get any sleep last night?" Scotty asked.

Montoya smiled. "Sleep? I have forgotten what it is. But perhaps if this plan of yours works, I will remember, eh? Then I can sleep tonight."

A check with the hotel desk told Rick that the scientists had left word that they were not to be disturbed until later in the morning except for an emergency. They had worked a good part of the night, apparently with no satisfactory results.

The boys waited until Ricardo Montoya had breakfasted, then rode with him to the airport. There was another wait while the radio engineers arrived, bringing the loud-speaker equipment.

Rick supervised the placement of the amplifier in the rear seat. The inverter was placed on the floor, and wedged into place with sc.r.a.p lumber. The automobile batteries were put into the luggage compartment behind the rear seat and were also wedged in place.

Wires were run from the amplifier through the rear-seat windows, which were opened just enough to take the thin cables. The leads were then brought out to the plane's struts. Two large loud-speakers were attached to the struts. At first there was some difficulty in figuring out a secure attachment, but the chief engineer, a resourceful type, managed to find a pair of U bolts somewhere in the hangars. They did the job nicely.

The chief engineer connected up, then hung the microphone between the two front seats. He threw a switch and the inverter started up with a whine. At the throw of a second switch, the loud-speakers broke into a hum. The engineer tapped on the microphone, and the tap, greatly amplified, reverberated across the airstrip.

"It works!" Rick exclaimed, delighted.

"_Como no?_" the engineer said with a smile. He spoke to Montoya in Spanish. The officer translated. "There is one more thing. He has rigged a cable with a switch box so you can operate the controls from the front seat. When the cable is attached, you will be ready. I will go call my uncle."

Rick and Scotty watched as the engineer got busy, hooking the remote-switch cable into the amplifier.

"Room for only two," Rick pointed out. "Want to toss for it?"
