Big Hobart Zircon, a nuclear physicist and long-time friend of the boys, tapped Scotty on the shoulder. "Since you're so certain of that, may I ask why you came?"
Scotty tried to look martyred. "Only because of the buddy system," he said solemnly. "The first rule of underwater safety—or above-water safety, for that matter—is that you have to swim with a buddy. You and Tony swim together, so I had to go along as a buddy for Rick. Somebody has to chase the mermaids away from him, and it might as well be me."
"That's nice of you," Rick said soberly. "There'll probably be a whole horde of mermaids guarding the treasure, not to mention half a dozen sea monsters."
Tony Briotti said, "There's one mermaid I wish were with us, and that's Barby. After all, she started this whole thing. Too bad she has to miss out."
Rick's pretty sister, Barbara Brant, had unwittingly launched the flight to the Virgin Islands by getting into an argument with Tony Briotti about the authenticity of the legend that pirates had once used Spindrift Island as a hangout. Tony had challenged the legend. After that, of course, proof had to be found.
Rick had recalled digging up the remains of a campfire in Pirate's Field during the installation of equipment for the moon rocket, the first great experiment that had put the Spindrift Island scientific group in business as a research foundation headed by Rick's father, Hartson Brant. It was during this experiment that Scotty had joined the staff after rescuing Rick from an unscrupulous gang. The two boys had been on a number of expeditions together since that time and were fast friends. Zircon was one of the original Spindrift group. Youthful Tony Briotti was one of the new staff members, but he had already earned the loyalty and friendship of the boys by his fine leadership of the expedition to the Philippines, as related in The Golden Skull.
Starting with the campfire site, Barby and the boys had excavated Pirate's Field under Tony's direction. They had unearthed positive evidence that pirates had landed there. The most vital evidence was the remains of a logbook, once the log of the bark Maiden Hand, sunk by the woman pirate Anne Bonney off the island of Clipper Cay in the Virgin Islands.
Scotty turned and looked at the two scientists. "I'm just kidding, of course. You couldn't have kept me from coming without tossing me into irons. But seriously, do you expect to find treasure, Tony?"
The archaeologist grinned. "Depends on what you mean by treasure. As I recall, one definition is 'something rare or precious.' Well, a chance to go skin diving in the Virgin Islands is certainly that—a rare and precious opportunity. At least I think so."
Hobart Zircon grunted, "And so do I."
