Besides, there were supplies and equipment to be picked up and charts to be obtained, and the Sky Wagon needed to have the tank topped off, since they couldn't very well carry aviation gas to the island.

Reluctantly, Rick asked, "Anyone want to see anything else?"

"Not me," Hobart Zircon said flatly. "I want to get to Charlotte Amalie so we can get started back. That water looks clear enough to drink."

"See any sign of wrecks on the bottom?" Tony inquired.

No one had. No one had looked. They were too interested in getting an over-all view of Clipper Cay.

Rick set his course for St. Thomas. Now that he thought about it, he was rather pleased with himself. The flight from Spindrift was the longest single trip he had ever taken in the Sky Wagon. The party had stopped for fuel as needed and had stayed overnight as darkness overtook them along the way. He had hit every destination on the nose, on time. And now the end of the trip was in sight without a single incident to mar its smoothness.

In a short time the mountains of St. Thomas rose out of the sea, and soon afterward Rick circled high above the colorful roofs of Charlotte Amalie. He switched on his radio and asked for seaplane landing instructions. The airfield directed him to the proper landing place, a beach and pier at the edge of the city. Then Scotty took over the mike and, while Rick started in for a landing, asked the airfield tower to phone Dr. Paul Ernst, Zircon's friend, and notify him of their arrival.

Apparently the tower operator phoned immediately, because as Rick taxied toward the dock, Zircon saw his friend waiting. Following the instructions of a dockman, Rick beached the Sky Wagon and cut the engine. Two husky Virgin Islanders hauled the ship higher onto the beach, and the Spindrifters climbed out.

Dr. Ernst was a small, bespectacled man with a shock of unruly white hair. He looked like a country doctor—which was reasonable enough, Rick thought, because that's just about what he was. Charlotte Amalie, with a population of about 11,500, could not be described as a big city.

The doctor greeted them all cordially, then immediately got down to business. "I'm sorry you are not remaining in Charlotte Amalie. However, Hobart, I have done as you requested. For tonight I have reservations for you at one of our oldest hotels, Alexander's Rest. Named for Alexander Hamilton, of course."
