“And going fast, too!” added Jerry. “Say, but they’re eating up the air-space all right!”

“I wonder if that can be Mr. Jackson?” ventured Ned.

“He’s far enough from here,” declared Jerry, referring to the millionaire whom they had so thrillingly rescued from his disabled dirigible balloon over the ocean.

“Whoever it is, he knows how to handle the craft all right,” declared Ned. “Look at that spiral dip he’s making.”

As he spoke the air machine came down a little way in a corkscrew curve.

“Wait!” exclaimed Jerry impetuously as he reached back in the tonneau and took from a pocket in the side a pair of powerful field glasses. “We’ll see what these show,” he went on, as he focused them on the distant aeroplane.

No sooner had he gotten the aircraft in his range of vision than he uttered a startled cry.

“What’s the matter?” demanded Ned.

“Some one you know?” asked Bob.
