"You're going to arrest them?" Rick asked.

"Of course! What did you think?"

"Right now?"

"If you want to come along, join me. Now is as good a time as any. If we can find them, of course."

The boys joined Montoya in the front seat of a military vehicle. The back was loaded with his men. Montoya at once steered for the trail to the volcanic pipe. It was only a thousand yards to the north from the point selected for the big hole. Even around the site of the hole there were diamond seekers, and it was hard to find a piece of ground that had not been tried with a shovel.

As they got closer to the diamond field the numbers of treasure hunters increased until, as Scotty remarked, they were thicker than fleas at a mutt show. Montoya had to lean on the horn continually, and even then the San Luzians paid little attention.

Finally the group got out and walked. It was easier to move on foot through the frantically digging mob. Strangely, there was little noise. Each individual seemed intent on his own little hole. But the digging was futile. There was no yellow ground under the flying shovels.

Then the group did reach yellow ground, and met rifles in the hands of Guevara's peons. Evidently Guevara had put a ring of men around the volcanic pipe and planned to hold it by force of arms.

Rick looked at Montoya. What would he do now?

The young officer looked haughtily at the nearest peons and demanded in Spanish, "Do you know me?"
