"What permit?" burst from Midkiff.
"From the Manatee Lumber Company, of course," Quibb told him. "I seen it."
"The permit!" chorused Midkiff, Cloudman, Phillips and Little Hicks.
"A letter from the lumber company permitting 'R. Kingdon and party' to camp on Storm Island for the summer?" asked Kingdon, softly.
"That's what I said," declared Enos importantly. "You fellers needn't think you kin gull me. I know——"
"Are you sure the permit was valid?" asked the blond youth, just as seriously as before.
"Huh?"
"For instance," he said, "was it typewritten on a Manatee Lumber Company letter-head?"
"Of course it was!" snapped Enos. "Think I'm a idiot?"
"Oh, I wouldn't say it out loud," returned Rex pleasantly. "Do you know the company's letter-head when you see it?"
