“There were many trees, methodically arranged, and some of them were of enormous height; there were animals in some of the enclosures, and they announced their presence by terrified squealings and snortings as they scented our queer, wild beasts and wilder human beings.” (PM XVI)
“The concrete buildings I had been hammering at in the early morning were occupied only by stock and farm produce, the house proper standing among a grove of enormous trees, and, like all red-Martian homes, had been raised at night some forty or fifty feet from the ground on a large round metal shaft which slid up or down within a sleeve sunk in the ground, and was operated by a tiny radium engine in the entrance hall of the building. Instead of bothering with bolts and bars for their dwellings, the red Martians simply run them up out of harm's way during the night. They also have private means for lowering or raising them from the ground without if they wish to go away and leave them . . .
“The water which supplies the farms of Mars is collected in immense underground reservoirs at either pole from the melting ice caps, and pumped through long conduits to the various populated centers. Along either side of these conduits, and extending their entire length, lie the cultivated districts. These are divided into tracts of about the same size, each tract being under the supervision of one or more government officers. Instead of flooding the surface of the fields, and thus wasting immense quantities of water by evaporation, the precious liquid is carried underground through a vast network of small pipes directly to the roots of the vegetation. The crops upon Mars are always uniform, for there are no droughts, no rains, no high winds, and no insects, or destroying birds.” (PM XXI)
