CHARACTERS THAT APPEAR IN THIS STORY.
=Matt King=, concerning whom there has always been a mystery--a lad
of splendid athletic abilities, and never-failing nerve, who has won

=Carl Pretzel=, a cheerful and rollicking German lad, who is led by a
fortunate accident to hook up with Motor Matt in double harness.

served his time in the King's navy, and bobs up in New Mexico where
he falls into plots and counter-plots, and comes near losing his life.

=Hector Brady=, a rival inventor who has stolen his ideas from

aëronautics, and who has built a successful air ship called the Eagle.

tragedy, and finally proved the complete undoing of Hector Brady.
