San Luz was in a state of complete chaos. The majority of the island people dropped everything as the word of treasure spread, and the slopes of El Viejo were covered with treasure hunters using everything from shovels to pointed sticks in an effort to find los diamantes. Only a bare handful even knew that the diamonds occurred only in a small volcanic pipe on the western slope.

If the hunt continued, Rick thought, the slopes would be denuded of vegetation.

There was intermittent fighting around the volcanic pipe, the police reported. Guevara's peons had succeeded in holding the diamond pipe, but were surrounded by soldiers. Now and then Guevara attempted to clear the entire area, but with the entire army struggling to dig diamonds he wasn't having much success. The police officer who investigated also reported that an American was with Guevara. That would be Connel, of course.

The scientists had moved at once to start shooting again, with the police pushing back the diamond seekers until the dynamite could be set off in safety. The crazed hunters assumed that the explosions were also means of seeking the diamonds, and rushed to the craters before the smoke had cleared.

No one really cared. The data was being collected, and it showed that the situation was growing extremely serious.

"Ten days maximum," Zircon said. "Maybe less. The magma has about reached that rock dike, and once it melts through, there goes the mountain."

"We must get the people off," Governor Montoya insisted. "That is the first thing. I shall call at once for help from the Americans. They have forces at the Canal Zone and also in the West Indies. They will send help."

"Yes," Hartson Brant agreed. "But first, we have a proposal. We will need the troops, but we may also need other help."

Governor Montoya looked at him keenly. "This proposal is perhaps a solution for El Viejo?"

"Perhaps. Let me outline the situation." The scientist pointed out the magma on Dr. Williams' sketch. "This is where the magma is now. Above it is a very thick layer of rock in which we can find no major weakness. It may hold the magma for a while. At least it probably will melt slowly."
