“I can,” he replied, “if you open quickly. I can last but a few moments more. But it is useless, they are both dead and no one else upon Barsoom knew the secret of these awful locks. For three days men crazed with fear have surged about this portal in vain attempts to solve its mystery.”
I had no time to talk, I was becoming very weak and it was with difficulty that I controlled my mind at all.
But, with a final effort, as I sank weakly to my knees I hurled the nine thought waves at that awful thing before me. The Martian had crawled to my side and with staring eyes fixed on the single panel before us we waited in the silence of death.
Slowly the mighty door receded before us. I attempted to rise and follow it but I was too weak.
“After it,” I cried to my companion, “and if you reach the pump room turn loose all the pumps. It is the only chance Barsoom has to exist tomorrow!”
From where I lay I opened the second door, and then the third, and as I saw the hope of Barsoom crawling weakly on hands and knees through the last doorway I sank unconscious upon the ground.
CHAPTER XXVIII
AT THE ARIZONA CAVE
It was dark when I opened my eyes again. Strange, stiff garments were upon my body; garments that cracked and powdered away from me as I rose to a sitting posture.
I felt myself over from head to foot and from head to foot I was clothed, though when I fell unconscious at the little doorway I had been naked. Before me was a small patch of moonlit sky which showed through a ragged aperture.
As my hands passed over my body they came in contact with pockets and in one of these a small parcel of matches wrapped in oiled paper. One of these matches I struck, and its dim flame lighted up what appeared to be a huge cave, toward the back of which I discovered a strange, still figure huddled over a tiny bench. As I approached it I saw that it was the dead and mummified remains of a little old woman with long black hair, and the thing it leaned over was a small charcoal burner upon which rested a round copper vessel containing a small quantity of greenish powder.
