from being ruined."

      Scotty spoke up from the rear seat. "There's one big fat flaw in that argument, boy. Would anyone care so much about business that he'd want to stay and be blown up? Who thinks more of business than he does of his own skin?"

      Zircon chuckled. "There may be such people, but I suspect they're scarce."

      Rick had to agree. He stared through the windshield at the tail of Brad Connel's jeep. The geologist was leading the way to the firing area, and he was alone. Hartson Brant had tried to assign one of the boys as a helper, but Connel had balked. He insisted that he did not need a helper, that he was used to handling charges alone, that he did not want to take the risk of an accident like that of yesterday.

      "Connel was pretty determined to go it alone," Rick remarked.

      "He's upset over the accident to Ruiz," Zircon pointed out. "He probably feels bad because he couldn't see Ruiz when he visited the hospital."

      Connel had gone into town with Dr. Balgos, and had paid a call at the Executive Mansion. While Balgos talked with Governor Montoya, recreating the stolen sketch from memory, Connel had been taken to the hospital by Lieutenant Governor Jaime Guevara. The hospital reported that Ruiz was on the danger list, his condition unchanged. He could have no visitors. Apparently both Guevara and Governor Montoya had tried to assure Connel that he should not be so depressed over what was obviously a freak accident.

      The trio stopped at their first station, and Connel waved, then continued on his way. Rick watched him out of sight, then turned to go to work. He remembered what the geologist had said the night before.

      "Connel figures we have months before the volcano blows," he remembered.

      "What?" Zircon looked up sharply. "How did he arrive at that conclusion?"

      "From Dr. Williams' sketch."

      "Hmmm." The big scientist checked the detonator thoughtfully. "He must have figured on a straight upward flow of the magma. But from the shape of the magma front, I think it's highly unlikely that it will progress in any such regular fashion. Instead, the front probably will increase erratically, but in a kind of progression. It may double its frontage at approximately regular periods."

      Scotty scratched his chin. "Double its frontage, huh? What does that mean?"

      "Maybe four hundred square feet today, eight hundred tomorrow, and sixteen hundred the day after. We won't know the rate of growth, or the time scale, until we've watched it for a while. But I talked with Balgos and Hartson last night at some length, and their opinion is that we probably have a couple of weeks, maybe even three or four. But not months."

      Rick whistled. "That fast? When will we be sure?"

      Zircon shrugged. "Can't tell. We'll keep shooting on a daily schedule, and perhaps in three or four days we'll see enough growth in the front to make an estimate. But even that can be misleading. If the magma strikes a softer area, it can grow even more rapidly. Our best bet will be to keep a daily watch from now on."
