They would get along well, his father and his boy. Both shrewd and practical, and yet both haphazardly romantic, as witness his father's impulse to buy land somewhere in the F. D. R. Mountains. It was a last gasp of hope springing eternal in the old man; here was land selling for next to nothing, with no takers, the authentic frontier which the habitable parts of Mars were patently not. Below him, Jack noted the Senator Taft Canal and aligned his flight with it; the canal would lead him to the McAuliff dairy ranch with its thousands of acres of withered grass, its once prize herd of Jerseys, now bent into something resembling their ancestors by the unjust environment. This was habitable Mars, this almost-fertile spiderweb of lines, radiating and crosscrossing but always barely adequate to support life, no more. The Senator Taft, directly below now, showed a sluggish and repellent green; it was water sluiced and filtered in its final stages, but here it showed the accretions of time, the underlying slime and sand and contaminants which made it anything but potable. God knew what alkalines the population had absorbed and built into its bones by now. However, they were alive. The water had not killed them, yellow-brown and full of sediment as it was. While over to the west--the reaches, which were waiting for human science to rare back and pass its miracle.

The archaeological teams which had landed on Mars early in the '70s had eagerly plotted the stages of retreat of the old civilization which human beings had now begun to replace. It had not at any time settled in the desert proper. Evidently, as with the Tigris and Euphrates civilization on Earth, it had clung to what it could irrigate.
