=Matt King=, otherwise Motor Matt, king of the motor boys.
=Carl Pretzel=, a cheerful and rollicking German boy, stout of frame as well as of heart, who is led by a fortunate accident to link his fortunes with those of Motor Matt.
=Dick Ferral=, a young sea dog from Canada, with all a sailor's superstitions, but in spite of all that a royal chum, ready to stand by the friend of his choice through thick and thin.
=Ensign John Henry Glennie, United States Navy.=
=Captain Pons=, who has come from Havre, France, to deliver the submarine boat, _Pom_, to the Chilian Government, only to fall into a net spread by the Sons of the Rising Sun.
=Captain Sandoval=, of the Chilian Navy, who has appeared before, in the MOTOR STORIES, and appears for the last time and bows himself out.
=Captain of the Port of Lota, Chili=, who plays a small but important part.
