A professor had told me once, in medical school, that the Polynesian seafarers dared their vast journeys through the trackless sea because they had learned to sense the currents of the ocean, the shifts of wind and tide, registering these changes with that most delicate of instruments-their testicles.

The absence of timekeeping equipment forced them to guess at then-longitude and they could easily lose themselves in the trackless sea.

What humanity was about to lose, though, except for one tiny colony on Santa Rosalia, was what the trackless sea could never lose, so long as it was made of water: the ability to heal itself.

From here the lesser roofs were almost a trackless sea, literally, and such a foreshortened one that it was very hard to trace the line of streets--a checkerboard viewed from the edge.
