The People of the Sea endured the horrors of the Thaw and by miracles preserved the vision Barratong bequeathed to them.
Meantime, the landsiders moved along the tracks and paths available.
Confronted by the rising water, they summoned droms and other mounts and loaded them, and struggled up steep mountainsides, collecting useful seeds and spores. Again and again the caravans were overwhelmed by hunger or sickness caught from murrained water, or trapped on a valley path when floods came rushing down. Desperate, some resorted to the use of fresh-water barqs, only to see them wilt and die when salt afflicted their tubules.
A few, however, found a way to safety, and after cautious negotiation settled on high ground near existing hamlets, being eventually made welcome because they had brought new food-plants and, above all, because they offered the chance of fertile first-time matings to communities whose numbers were diminishing.
Following the caravans, though often having to invent new routes, discontented wandering scholars trudged from town to new town seeking their lost equals, each bearing something of what had been known in a city sunk beneath the waves or lost when a hillside slumped into the sea. Occasionally they borrowed the services of the tramp junqs which, after the dispersal of the Lesser Fleets, traveled in groups of three or four and traded as best they could along inlets of the sea that formerly had been mountain passes or river-valleys. The hegemony of the People of the Sea endured, but the mixing of the landsiders resulted, almost at once, in an explosion of population, for instead of one pairing in several score producing a bud, suddenly five took, or even seven, and wise persons argued about miscegenation, and proper diet, and the influence of privation, and it seemed that most of them must be at least partly correct.
The sea-level stabilized. Those fortunate astronomers who had access to long-term brightness records for the sun admitted cautiously that it looked as though the extra heat due to infalling matter was over. Those who had preserved their presence of mind during the period of violent quakes, devising means to mark and measure the trembling of the land, noted with satisfaction that it shook only now and then, and hilltops seldom broke loose anymore. Such scientists, when they met them, the People of the Sea declared to be Jingfired, and gave them copies of the ancient star-maps. It was a mere token, for the donors scarcely understood what the maps recorded, yet they were seeds of knowledge, after their fashion. The skies cleared, and there was no longer a gritty stench when the wind blew from the north. Daringly, a few started to maintain that an outburst of volcanic dust had protected life on the planet from the worst effects of increased solar radiation … but it was at best a guess, lacking evidence.
When the world settled back to an even keel, explorers set forth once more who employed techniques that once had been the private property of jealous cities: means to signal across vast distances, means to preserve knowledge by multiplying it in countless copies; medicines to cure common illnesses, others to master strange rare disorders; tools for tasks that most people had never dreamed of undertaking; seeds so treated they would yield edible fruit simply by being soaked in salty water when required; vegetable parchments that changed color when light shone on them, which placed at the proper distance from a lens would fix an image; juices and saps which served to bind together plant and rock, or glass and metal; vessels not of wood or hide but melted sand, not exactly glass but stiffer, wherein a fire might safely be lighted on the back of a junq without the creature suffering…
Tricks and ideas, hints and suggestions, cross-fertilized and bred faster than the population. A means was needed that would match one invention, to be exchanged, against another. After much fierce debate, it was agreed that persons schooled in the desired technique should be the unit, and the surviving Little Fleets should carry them for longer or shorter periods among the folk requesting the new knowledge. By now, however, many of the new cities had their own research groups, not to mention their own miniature Fleets and the system rapidly broke down.
