CHARACTERS THAT APPEAR IN THIS STORY.

=Matt King=, otherwise Motor Matt.

=Joe McGlory=, a young cowboy who proves himself a lad of worth and character, and whose eccentricities are all on the humorous side. A good chum to tie to--a point Motor Matt is quick to perceive.

=Ping Pong=, a Chinese boy who insists on working for Motor Matt, and who contrives to make himself valuable, perhaps invaluable.

=Amos Murgatroyd=, an enemy of Motor Matt, and who cleverly manipulates the various wires of a comprehensive plot only to find that he has championed a losing cause.

=Amy=, Murgatroyd's niece, who helps right and justice, turning against a relative in order to befriend a stranger.

=Siwash Charley=, a ruffianly assistant of Murgatroyd who proves to be one Cant Phillips, a deserter from the army.

=Pecos Jones=, who has no principles worth mentioning, plays a double part with friend and foe, and abruptly vanishes.

=Lieutenant Cameron=, an officer in the Signal Corps, U. S. A., who proves to be the cousin of an old friend of Matt, and who nearly loses his life when the aëroplane is tested.
