ancient, tarnished hull of the Astronaut held its path about the Sun. But that amazing perception, that inexplicably had showed me so much, began as inexplicably to fail. In the last ten thousand years, I had noted, men had begun to feel an alarmed and puzzled resentment against the gift of Malgarth's technomatons. But, before I understood what was happening, all contact faded. The stars were blotted out. The Sun was gone. I was no longer aware of the rusted metal about me, or even of my body. The universe was a void of darkness. I lived through eternities of lonely despair. Was my mind, I wondered bleakly, joining my body in death?

My body, that had been stiffly moveless for unmeasured ages, was suffused with prickling pains. The effect of Dr. Crosno's drug was passing, perhaps because of the age-long disintegration of the uranium salts it had contained. With a wrenching, agonizing effort, I moved one
