"Thought I'd never get you out," he said, stepping, uninvited, into the room and taking a chair. "Thought that you ought to know what's been going on."

Ned had little confidence in Collins. The fellow's strange conduct of the night before naturally made the boy suspicious. After requesting a ride in the Nelson, or, at least, the company of the Boy Scouts to the place where the machine had been left, he had disappeared without a word of explanation.

It seemed to Ned that he had good grounds for the belief that Collins had spied around until he had learned that the aeroplane was going up, and had then communicated the information to the man on the white machine. At least, the strange aviator had shown in the air directly after the disappearance of Collins.

But it was no part of Ned's purpose to permit Collins to see that he was suspected. It was rather his idea to keep on good terms with the fellow and watch him for any evidences of treachery. He therefore greeted him cordially and asked:

"Something interesting going on in the city? We did not return until nearly dawn, and I've been asleep ever since."

"You haven't heard about the attack on our aeroplane, then?" asked
Collins, looking Ned over keenly.

The boy tried not to exhibit the least emotion or excitement at the disturbing question. Leaning back in the chair he had taken, he asked:

"The curiosity of the people got the better of their courtesy, eh? I have been afraid of that. Well, I hope the Nelson was not seriously injured."

Thomas Q. Collins had the appearance of one who had expected to unwrap a great sensation and had failed. His face was a study.

"Well, no," he replied. "The fact is, when the rush was made the aeroplane shot up into the air."
