Rh He breathed more easily when he saw that Andy was not in sight, and a hurried inspection of the aeroplane did not disclose that it had been tampered with.

"Anything the matter?" asked Mr. Swift, as he followed his son.

"No, but when you mentioned that Andy was out here I thought he might have been up to some of his tricks. He had a little trouble with Eradicate this morning, and he threatened to get even with me for it." And Tom told of the whitewashing incident.

"I just happened to see him as I was coming to dinner," went on the aged inventor. "He hurried off when he noticed me, but I thought he might have been here to leave another letter."

"No," said Tom. "I must tell Eradicate to keep his weather eye open for him, though. No telling what Andy'll do. Well, I must finish eating, or Ned will be here before I'm through."

A little later Ned arrived, and helped Tom start the motor. With a roar and a bang the swift little machine rapidly got up speed, the propellers whizzing around so fast that they looked like blurs of light. The sky racer was held back by a rope, as Tom wanted to note the "pull" of the propellers, the force they exerted against the air being registered on a spring balance.
