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 semiarid 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.
