They would have a wonderful time, Rick thought, and who knew? They might even find the treasure!

Scotty had been looking through the binoculars again. He gave Rick a grin. "I take it all back," he said. "There's an island ahead."

The scientists leaned forward eagerly, and Rick strained to see. Sure enough, in a few moments they began to make out the island on the horizon ahead. Rick had enough confidence in his navigation to be certain that it was Clipper Cay.

The group had spent the night in Puerto Rico, then departed early in order to fly off the direct route for an advance look at Clipper Cay. Rick didn't intend to land. He would circle the island once or twice, then head again for Charlotte Amalie on the island of St. Thomas.

Scotty asked, "Where does the word 'cay' come from, anyway?"

Tony Briotti answered. "It's from the Spanish, Scotty. It means island, or islet. However, the Spanish got it from the Taino people, who were the Indians of the Antilles."

The island was close enough now so that they could discern its shape. Rick saw that it formed a rough crescent, running from north to south. It was about a mile long, perhaps a half mile wide at its greatest width, tapering to the horns of the crescent. He saw also that the color of the water changed gradually from the fathomless blue of the ocean to the green of shallow water.

Inwardly excited, he put the nose of the plane down and let the small craft pick up speed. Scotty grinned his pleasure, and Rick knew that his pal was just as excited in spite of his joking skepticism.

Rick leveled off at an altitude of four thousand feet and put the plane in a wide circle. Zircon leaned over Tony to look out the window, and Rick had to compensate in a hurry because the big scientist's weight threw the plane out of trim. Then Scotty, just as eager, leaned over to Rick's side and the trim had to be corrected again.

The island was a travel agent's wildest dream. The blue water gradually shifted to green, then lighter green, and finally the white of lovely beaches on both sides of the island. Lines of surf marked the position of reefs off both shores.
