When Linda and Dot arrived at the airport they found the Ladybug in readiness for its second flight into the swamp. Linda inspected her, and piled in the equipment.
"I feel as if the Okefenokee Swamp were my home," she remarked, as she headed the autogiro in that direction. "I could almost fly it blind!"
"Don't!" warned Dot. "Your friend the Doc is still at large, and he may be watching for us with a gun."
This was Dot's first view of the swamp, and as they approached it, she was amazed at the vast expanse of it, stretching out in every direction.
"It's huge, isn't it?" she shouted to Linda, through the speaking-tube.
"Forty miles long and thirty wide," was the reply. "But we see only the southern end of it."

"Shall we get out?" she asked her companion. "Or go straight on to the ocean?"
