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.

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.
