It was as Jimmie had said. A giant monoplane, resembling in its conformation a great bird, was rapidly approaching the Grey Eagle.
"Let's give him a run, Ned!" cried Jack excitedly.
"Sure!" acquiesced Ned. "We'll show him a little speed!"
Accordingly he turned on power and in a moment the Grey Eagle was skimming along at a great rate. In order to better manipulate the machine Ned inclined the planes and ascended several hundred feet.
"The other fellow is climbing, too!" reported Jimmie.
"Is he gaining any?" inquired Ned, busy with the levers.
"You're right, he is!" answered Jimmie. "He's overhauling us!"
"Well, let him come," Harry suggested. "This is a trial trip!"
"How near is he now?" asked Ned over his shoulder.
