"But what do you expect to find?" Cub inquired.
"I don't expect to find anything. I had no expectation when I suggested that you boys canvass the radio field for information to clear up what you chose to call a mystery. I had no idea what might turn up as a result of such canvass, but I know it was about the only thing for you to do to start a move in the desired direction."
"And something sure did move," Hal remarked appreciatively.
"Well, let's run around this island and find a landing place," Cub proposed.
The run was made, with Cub in charge of the wheel and engine controls.
They circumnavigated the island with unsatisfactory result.
"That settles it," Bud declared. "If San Salvador had been like that,
Columbus would have made his first landing somewhere else!"
"Robinson Crusoe would never have found any footprints in the sand there," Hal declared.
"Yes, we'll give it up for the time being," Mr. Perry declared. "We won't try to scale any perpendicular banks, fifteen or twenty feet high, at least, not to begin with."
"I tell you what we ought to do," Hal volunteered next. "Let's accept this island as the center of probability."
"What in thunder is that?" Cub demanded.
