"Perhaps, Rick," Dr. Williams answered. "We don't really know. Dr. Balgos thinks they mean a great deal, and I have respect for his opinions. But I'm only a seismologist. I have to depend on traces from earthquakes, and the traces tell us nothing but the single fact that something is going on far below."
Hartson Brant nodded. "The answer will depend on more data, so today we'll start to collect it. Rick and Scotty brought apparatus, and the governor has supplied us with dynamite and two experienced helpers, Ruiz and Honorario."
"How do we split up?" Julius Weiss asked.
"Into firing and recording teams. Since we have only two recorders, we can have only two teams for data collection. But we can have three firing parties. Dave Riddle will work with Honorario, Brad Connel with Ruiz, and Hobart Zircon with Rick and Scotty. Julius, you and I will form one recording party, and Esteben and Jeff will form the other. Each team will have a jeep. Now, if you'll all gather around this model the boys made, we'll pick approximate locations for stations."
The boys had brought the model with them. Now the group gathered around and discussed the best locations for both firing and recording parties.
Dave Riddle was assigned a station on the slope of El Viejo near the town of Redondo on the north end of the island. Brad Connel was given a location on the northwestern slope, and Zircon and the boys were shown a position on the west near the place where pumice, a foamy volcanic rock, was mined. Hartson Brant and Julius Weiss were to place one recording station on the eastern slope of the mountain, while Dr. Williams and Dr. Balgos were assigned a station on the northern coast.
Hartson Brant handed a wrist chronometer to each team leader. Each team was also to have a transit, with which to take bearings for the purpose of locating the stations with precision.
"The hotel restaurant has packed lunches for us," Hartson Brant stated. "If we get under way at once, we can start shooting at one o'clock. Let's try for three shots each this afternoon. Each firing team will move one mile in a clockwise direction between shots, and we'll need to space the shots fifteen minutes apart. Hobart, you'll start shooting at 1:00, Brad at 1:15, Dave at 1:30. At 2:00, we'll start the cycle over again. That should bring us all back to the hotel by suppertime."
Big Hobart Zircon clapped the boys on the shoulder. "Let's get going. Scotty, you pick up our lunches. Rick, we'll load equipment."
The five jeeps were lined up outside. Rick carried out a transit, the tripod slung over his shoulder, and found the two local helpers waiting. Ruiz was a short, swarthy man with gleaming white teeth and a Mexican-style sombrero. Honorario was only slightly taller, and so thin a strong breeze would blow him away. The two San Luzians greeted him courteously. "Buenos días, señor."
