Edgar Rice Burroughs: A Princess of Mars

7. CHAPTER VII: CHILD-RAISING ON MARS (continued)

Each adult Martian female brings forth about thirteen eggs each year, and those which meet the size, weight, and specific gravity tests are hidden in the recesses of some subterranean vault where the temperature is too low for incubation. Every year these eggs are carefully examined by a council of twenty chieftains, and all but about one hundred of the most perfect are destroyed out of each yearly supply. At the end of five years about five hundred almost perfect eggs have been chosen from the thousands brought forth. These are then placed in the almost air-tight incubators to be hatched by the sun's rays after a period of another five years. The hatching which we had witnessed today was a fairly representative event of its kind, all but about one per cent of the eggs hatching in two days. If the remaining eggs ever hatched we knew nothing of the fate of the little Martians. They were not wanted, as their offspring might inherit and transmit the tendency to prolonged incubation, and thus upset the system which has maintained for ages and which permits the adult Martians to figure the proper time for return to the incubators, almost to an hour.

The incubators are built in remote fastnesses, where there is little or no likelihood of their being discovered by other tribes. The result of such a catastrophe would mean no children in the community for another five years. I was later to witness the results of the discovery of an alien incubator.

The community of which the green Martians with whom my lot was cast formed a part was composed of some thirty thousand souls. They roamed an enormous tract of arid and semi-arid land between forty and eighty degrees south latitude, and bounded on the east and west by two large fertile tracts. Their headquarters lay in the southwest corner of this district, near the crossing of two of the so-called Martian canals.

As the incubator had been placed far north of their own territory in a supposedly uninhabited and unfrequented area, we had before us a tremendous journey, concerning which I, of course, knew nothing.
