ll. Don't you see it's one of the stolen ones. Look at the red
circle upon the back."

"Jove! So it is. But, what, how----"

"Hush! Don't talk so loud. This wallet, which contained it, was jolted out
of Roy Prescott's pocket when he was hurled from the machine. The wallet
and--and something else. But don't you see what power that gives us?"

"No. I confess I'm stupid, but----"

"Oh, how dense you boys are," exclaimed Regina, with an impatient stamp of
the foot, "don't you see that this bill will come pretty close to proving
Roy Prescott a thief, if we want to use it that way? You are a witness
that I found it in his wallet which had been jerked out of his pocket.
Isn't that enough?"

"Well, men have been sent to prison on less evidence," said Fanning, with
a shrug; "but I've got to hurry up with this water or they'll suspect
something. I'll talk more with you about this later on. Your father and
mine need every bit of fighting material they can get hold of, if we are
to win the big prize for the Mortlake aeroplane."

A shadow fell athwart the road as Fanning, an evil smile on his flabby,
pale face, hastened down into the depression in which Roy, with Peggy
bending above him, still lay. The girl looked swiftly up. A big, red
aeroplane was hovering on high. Presently one of its occupants, a girl

The new arrivals were Jimsy and Jess. They had set out on a sky cruise to
the Prescott home, and Jess's bright eyes had espied the confusion in the
road beneath them as they flew over. The swift descent had been the
result.

Hardly noticing Regina, who regarded them curiously, the young sky sailors
hastened toward the spot in which, from on high, they had seen the injured
boy lying. A warm wave of gratitude swept over Peggy as she looked up at
the sound of footsteps and saw who the newcomers were. In an emergency
like the present one she could not wish for two better helpers than the
Bancrofts.

Jess and Jimsy had been off on a visit and so had not been made aware of
the fact that Fanning had returned to Sandy Beach. Their astonishment on
seeing him may be imagined. Jess regarded him with a tinge of disdain, but
the frank and open Jimsy grasped the outst
