A second and third door receded before me and slipped to one side as the first, before I reached a large inner chamber where I found food and drink set out upon a great stone table. A voice directed me to satisfy my hunger and to feed my calot, and while I was thus engaged my invisible host put me through a severe and searching cross-examination.

“Your statements are most remarkable,” said the voice, on concluding its questioning, “but you are evidently speaking the truth, and it is equally evident that you are not of Barsoom. I can tell that by the conformation of your brain and the strange location of your internal organs and the shape and size of your heart.”

“Can you see through me?” I exclaimed.

“Yes, I can see all but your thoughts, and were you a Barsoomian I could read those.”
