There is a third science-fiction series by Edgar Rice Burroughs, which I have not discussed to this point because the stories were written relatively late in Burroughs' career. This third series, concerning the deeds of Carson Napier on the planet Venus, date from the early 1930s, constituting four books plus an additional novelette which appeared in the posthumous collection Tales of Three Planets.

Stung now, Kline retaliated for Burroughs' invasion of his Venusian do-
