Edgar Rice Burroughs: A Princess of Mars

20. CHAPTER XX: IN THE ATMOSPHERE FACTORY (continued)

"You wear the metal of a green warrior and are followed by a calot, yet you are of the figure of a red man. In color you are neither green nor red. In the name of the ninth day, what manner of creature are you?"

"I am a friend of the red men of Barsoom and I am starving. In the name of humanity open to us," I replied.

Presently the door commenced to recede before me until it had sunk into the wall fifty feet, then it stopped and slid easily to the left, exposing a short, narrow corridor of concrete, at the further end of which was another door, similar in every respect to the one I had just passed. No one was in sight, yet immediately we passed the first door it slid gently into place behind us and receded rapidly to its original position in the front wall of the building. As the door had slipped aside I had noted its great thickness, fully twenty feet, and as it reached its place once more after closing behind us, great cylinders of steel had dropped from the ceiling behind it and fitted their lower ends into apertures countersunk in the floor.

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."
