The 5th Section
The Green Morning
Benjamin Driscoll -- He is one of the Martian Chronicles characters with a strong reaction to the environment -- he almost has to go back to Earth because of the thinness of the air. He plants trees everywhere to build up the oxygen levels.
Muhe Ca -- He is a Martian who may or may not be real -- he may be from a different dimension.
Toma's Gomez -- He is one of the earliest settlers.
Way in the Middle of the Air
Mr. Teece -- He is a storekeeper -- and a racist who has taken part in hangings, and when he finds out that blacks want to colonize Mars too, he is scandalized.
Belter and Silly -- They are two black men who work for Mr. Teece. Belter owes Mr. Teece $50, so the store owner won't let him leave until the debt is paid. Silly almost does not get to leave, because he has signed a contract to work for Mr. Teece for a fixed time period, but Mr. Teece gives in and lets him leave.
William Stendahl -- He loves fantastic literature along the lines of Lewis Carroll and Edgar Allan Poe. On Earth, those authors had been censored.
Garrett -- He is one of the Investigators of Moral Climates, and he investigates Stendahl's house (Usher, a clear allusion to Poe) using a robot copy of himself -- and later goes himself.
