It was hard for Mr. Barr to believe that the man whom he trusted implicitly could have proved traitor to him.
"The best way to find that out is to look at your papers and models and see if anything is missing," was the response.

"Our young friends were right," he said. "In detecting the rascal they have done an excellent piece of scouting work. But now let us hurry off in search of Rob at once."
"How will you reach that other island?" asked Merritt.
