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._" Rick knew enough Spanish to be equally polite. "_Buenos días, señores. Cómo están ustedes?_" The two switched to English. Rick hoped it wasn't a reflection on his Spanish accent, acquired at Whiteside High School the year before. "We are well, señor," Ruiz answered, and Honorario added, "We hope you will enjoy San Luz, señor." Rick said that he expected to enjoy it very much indeed. He wondered if the two knew that their mountain was getting ready to blow its top. He asked, "Do you have the dynamite, _amigos_?" "In the shed, señor. Also the caps and the detonators. If you will come, I will show you." Ruiz gestured toward a concrete shed that stood some distance away. "What was the shed used for?" Rick asked as they walked toward it. "It is a shed for a pump, señor. The pump is for the hotel's water, which must be brought up the hill from Calor."
