Peetn lay the inert figure back on the ground and gazed fascinated at the face, now relaxed in repose. From whence had this stranger come? Mars could never have spawned such a creature! This was a being from another world, maybe from Gamtl itself! Peetn thrilled at the thought as he lay himself down to a food-and-water-less bed.
Long, long ago the savants had predicted the death of Mars, the gradual wasting away of its ability to support life, until finally the last Martian would die alone. They pointed with eagerness and envy in their telescopes at the soft green sphere of the third planet, picturing it as the Martian Eden, teeming with life-giving food and water.
Space ships were built. There was not nearly enough room for the entire population of Mars aboard, so it was agreed that they should act as ferries, shuttling back and forth until Mars was evacuated.
The first contingent departed one day on the long trek to another world, and the people left behind waited with renewed hope for their turn to go. Hope turned to uneasiness as a second fleet of ships rocketed toward Paradise, many years after the first ones should have returned. A third and fourth fleet followed at ever-lengthening intervals, and with ever-lessening numbers, but all vanished into obscurity with the same finality.
Weakening civilization soon could no longer strain the necessary resources from the perishing planet to send another fleet; Gamtl, the lush, life-choked pleasure-laden Paradise, became a myth of the past, and then even the myth became dim and half-remembered.
Life was a sodden series of hungry days and frigid nights. The energies of each individual were strictly circumscribed to activities designed to give his colony one more day, one more hour of life. Birth, when it was allowed at all, was limited to the replacement of necessary personnel to carry on the food gathering of the community. All contact, outside of occasional meetings between scouts searching for new patches of merrl bushes, was lost between the colonies, which had settled on the dust-covered sites of the ancient cities because of the trickle of water which still issued from the massive pipes. Even the sporadic raids made on the water stations were abandoned, and as the danger of attack lessened, small and smaller numbers of guards were spared from the duties of procuring merrl from the desert wastes, until finally only one made the food-and water-less trip into the northern steppes of the polar region. Every fifth year another was sent to relieve him, but the oldest man in the colony could not remember when one had returned. What privation, what utter loneliness these martyrs endured would never be known. What acts of heroism they might perform would go forever unsung.
Peetn had been very young when he had set out for the far north and five years of Martian hell at the water station, but the two years that had passed so far had left him a dead-hearted, middle-aged Martian. Wrinkles had appeared on his eye-sacs, and his fur had become sparse and gray. His mind, too, had turned gray, had withered from watching too many sunsets. He came to feel inside that he would never see his colony again, just like the others.
In spite of his activity the day before, Peetn was up and about early the next morning and went into the desert for merrl. Before he left, however, he placed the metal container half-full of water beside the still-sleeping figure in the metal suit. An intermittent buzzing sound issuing from its mouth startled him, and he opened the faceplate. The sonorous sound stopped abruptly with a snort, and the stranger mumbled a few words and squirmed in his sleep. Peetn hastily but softly closed the lid and ambled off into the sea of rock and sand.
