"The History Holocaust!"
Helium's most eminent scientist, Tallus labors over the finishing touches to a device meant to detract John Carter from Mars. Yet another anti-JC Red Man with a grudge to bear.
Tallus lures the Jasoomian under the ruse of attending an exhibition at his lab. Carter is bored and doesn't pay close enough attention to his surroundings, until the green ray hits him.
Whether illusory or reality, John Carter relives Earth history past, either as great iconoclasts or close attachés to them. It's only a dose of wholesome Barsoomian beauty that shocks him back to the present with a vengeance.
"Tales of Barsoom!"
John indulges in a spot of pre-bedtime reading as the svelte form of Dejah Thoris approaches him from behind. This particular tale documents the origins of life on the red planet Mars, and all its offspring races.
