Freddy pulled out his compass and held it steady in one hand. He peered at it intently for a moment.
"Right-o," he said presently. "If we hold a course fourteen points east of north we'll be traveling a straight line toward that spot. As soon as we get down off this escarpment we won't be able to see the spot all the time. But this compass will take care of that. Right-o. Let's get started."
"Hey, hold everything!" Dave cried, and held Freddy back. "A fine Indian scout, you are! And have you forgotten everything you learned about aerial combat, huh?"
Freddy stared at him in wide-eyed amazement.
"What in the world is eating you, Dave?" he gasped. "Aerial combat?"
"Sure," Dave said with a nod. "What's the best way to sneak up on an enemy ship for a surprise attack?"
"Come down on him with the sun at your back, so it's extra hard for him to see you," Freddy replied promptly. "So what of it?"
"Plenty," Dave said, and pointed to the west. "The same idea holds good right here. We'll circle around to the west for a spell, and then creep up on them with the setting sun at our backs. That way we can get much closer. Less chance of anybody spotting us. Right?"
Freddy grinned a bit sheepishly and nodded.
"The young man is right," he said. "He's absolutely correct. My apologies and congratulations, sir."
