The males worked at the surface of the canals, or in open excavations. Their wide, mutated hands chipped into the rock-hard clay, opening a channel which was to be filled with sand and then sealed off with clay on all sides and surface. That water might seep through the sand without evaporation, without loss, from the poles to the equator of Mars—seep unimpeded, so that moisture might reach the lichen plants of everyone, so that none might thirst or hunger.
The seepage must flow. Not even buried in the dim racial memory had there ever been one who took more than his share, for this would be like the fingers of one hand stealing blood from the fingers of the other.
Among the Mars race there were many words for contentment, kinship of each to all. There were words to express the ecstasy of watching the eternal stars, by night and by day, through the thin blackish atmosphere. There were words to express the joy of opening slitted nostrils to breathe deeply in those protected places where the blowing sands did not swirl, of opening folds of rubbery skin to catch the weak rays of the distant Sun.
