The man did not mention his name. He seemed to care nothing
whatever for the fate of the launch. He barely thanked Dave, as,
reaching the aero grounds, our hero led him near to the headquarters
of the man for whom the Dawsons were working.

"You'll find your friends over there," he said.

"All right," nodded the man he had rescued. "Lucky I met you.
Thanks."

"Say, Dave Dashaway, now what do you think of that!" burst out
Hiram, as the man got out of earshot.

"Think of what, Hiram?" inquired the young aviator.

"Friend of the Dawsons!"

"Well, they've got to know somebody, haven't they?"

"That's so, but I don't like the fellow you rescued."

"Why not, Hiram?"

"Did you notice the way he hesitated when we asked him where he had
come from?"

"Yes."

"And about that launch? He didn't seem to care what had become of
it."
