“Bixby doesn’t own these machines!” exclaimed Carl angrily.
“Who does own them?” demanded Doran.
“We four boys own them!” was the reply.
“Well, you’ve got to show me!” insisted Doran, insolently.
“I’ll tell you what we’ll do!” Jimmie announced. “We’ll go right back to Bixby and put you off the job!”
“Go as far as you like,” answered Doran. “I was put here to guard these machines and I intend to do it. You can’t bluff me!”
While the boys stood talking with the impertinent guard they saw two figures moving stealthily about the aeroplanes. Jimmie hastened over to the Louise and saw a man fumbling in the tool-box.
“What are you doing here?” demanded the boy.
The intruder turned a startled face for an instant and then darted away, taking the direction the cab had taken.
Carl and Doran now came running up and Jimmie turned to the latter.
