"No. If I know this man Guevara, any such move would mean the death of my uncle, if he still lives. We must find some other way."

"Can you find loyal people?" Rick asked.

"A few. You must understand most people do not feel as I do about Guevara. He is popular. Who knows where the loyalty of the people lies, between individuals? One cannot be certain. So, I must use only men loyal to me. There are such."

Montoya rose. "We will be allies, since we fight for the same thing, which is San Luz. Let me see what kind of plan can be made. Go back to your hotel, and I will come for you there. We will work this thing out together." He shook hands with both boys, turned, and strode from the restaurant.

Rick paid for their coffee and the boys joined Honorario, who was waiting outside in the jeep. "He's a good, tough hombre," Rick told the San Luzian. "You made a good choice."

"I am glad," Honorario said. "Someday he will be governor, like his uncle."

While the boys were in Calor, the scientists had conducted another series of shots. The tracings were spread out on the table when they returned, and the group was engrossed in checking them over.

Rick and Scotty waited, watching. They knew from the quiet voices and tense attitudes that something serious had been found. Then Williams began to mark in the data on his sketch.

"This is where the explosion took place," he said. "Probably the magma hit a quantity of water as it entered the new channel. Notice that the channel is one we marked on here earlier as a probable path. So far, we're guessing right. Now, my estimate is that the magma will move fast, stopping only when it reaches this dike of solid basalt."

Hartson Brant wiped his face with his handkerchief. "It looks bad, Jeff. The magma will reach the solid layer before we could possibly get to it with a tunnel."
