"Lucky thing Ike didn't bring that engine over to the shop," commented Dunk. "We never would have gotten that out."
"Pretty good luck all around," responded Hawke, optimistically. "So cheer up, and let's get busy right away this afternoon repairing the Thunder Bird. If we're goin' to chase thieves we've got to get at it soon."
In the afternoon, Carl, whose active spirit chafed under the restraint put upon him by Dr. Rivers, broke bonds and escaped from the sickroom. The boys were industriously working on the plane when he appeared, a little haggard and hollow-eyed, at the hangar.
"Hello there, old scout," exclaimed Herb heartily. "Glad you're out."
"Was she much smashed up?" asked the Indian, smiling rather forcedly.
"Not much, we can mend her up in a couple of days," responded Hawke.
"Too bad we went under before we got her clear out," continued Carl, "but I'm glad it isn't damaged worse than it is."
"Guess I'll take a walk over to the cliffs," added the Indian, reflectively. "There's enough of you working on this."
"The cliffs?" echoed Fred interrogatively.
"Yes, I'm going to see if I can scare up that confounded Indian," responded Carl, shutting his lips rather tightly, a light in his eyes which the boys had never seen there before.
