“I’ve got hot news!” he announced. “A yellow biplane was sighted yesterday, flying with all possible speed towards the Pacific Ocean. I got that from Los Angeles headquarters last night.”

Linda’s eyes sparkled with excitement.

“We’ll be right after them,” she said. “Oh, if we’re only not too late!”

“It’s a peach of a day,” commented Dot. “If it is hot.”

“Heat doesn’t bother me,” returned Linda, climbing into the cockpit, and setting the rotors in motion. “Get in—if you’re coming with me!”

Linda gave her the gun, and the Ladybug left the beach a minute or so later, soaring triumphantly into the skies.

“We’re going to fly high, now!” shouted Linda. “And we’re going to make speed!”

The outlines of the island faded and disappeared from their sight; even the water was lost to their view. The Ladybug flew as if she were on a test flight, to prove her ability to take part in any kind of service. Mile after mile disappeared as Linda watched her instruments and her map closely, for now she could figure just about how far she had to go to reach the coast of the peninsula. All the while Dot scanned the air with the glasses, looking for a flash of yellow in the sky.

“We are over an airport town now,” Linda announced about one o’clock. “Shall we come down for lunch?”

“No! No!” returned her companions. “We’ll dig out something from the box, and eat as we go. On to the coast!”
