"We'll take you," Rick said. "Let us get tanks from our boat. There should be a pair fully charged by now."
Steve shot a look at the doctor. The officer shrugged, then nodded. "Okay, if it's a short dive. They've had plenty for today."
"Chief? Where are you?" Kelly called.
A frogman stepped from the rear of the group. "Here, Sir."
"Check their regulators, please. If they're okay, hook up fresh tanks. If not, loan them complete outfits."
"Yes, Sir."
"Thanks, Chief. Then get set to come with us. Danny, Jonesy, Mike, and Dick come along, too. Bring still and motion-picture cameras. When we get down, split into two-man teams and search the area. You know what we're looking for. It's just like the one we found off St. Croix."
Rick stared at the frogman officer. Another brass ball off St. Croix? But there wasn't time for questions.
"Quick dive, please," Zircon requested. "These boys have had enough."
"They're through as soon as they show us the cave," Steve agreed. "Come on, gang. Let's get to it."
