The journey to the heart of the moon was made possible by the invention of a wonderful interplanetary cruiser called the Barsoom. Propulsion through the cold immensity of space was gained through use of the Eighth Ray, a discharge of electrical energy exhausted by all the heavenly bodies, and which required only to be harnessed by the marvelous Eighth Ray tanks of the Barsoom in order to send the steel ship to any spot in the universe. Don't fail to read this startling story of the adventures of Julian and Nah-ee-lah the Moon Maid in Va-nah, the marvelous lunar country which exists under the crust of the Moon.
