Greybeard. Chapter 7. The River: The End
VII. The River: The End
Wild life swarmed back across the Earth as abundantly as it had ever done. In its great congress, there were a few phyla absent; but in numbers the multitude was as rich as it had ever been.
The Earth had great powers of replenishment, and would have as long as the sun maintained its present output of energy. It had supported many different kinds of life through many different ages. As far as that outcast spit of the European mainland called the British Isles was concerned, its flora and fauna had never entirely regained the richness they enjoyed before the Pliocene. During that period, the glaciers descended over much of the northern hemisphere, driving life southward before them. But the ice retreated again; life followed it back towards its northern strongholds. Towards the end of the Pleistocene, like the opening of a giant hand, a stream of life poured across the lands that had recently been barren. The ascendancy of man had only momentarily affected the copiousness of this stream.
Now the stream was a great tide of petals, leaves, fur, scales, and feathers. Nothing could stem it, though it contained its own balances. Every summer saw its weight increasing as it followed paths and habits established, in many cases, in distant ages before homo sapiens made his brief appearance.
The summer nights were short. They retained something of the translucence of the day, only losing the last of their warmth as light seeped once more across the landscape, so that the sigh of cool air that brought dawn ruffled the pelts of animals and the feathers of innumerable birds as they woke to another day of living.
The rousing of these creatures provided the first sounds to be heard every morning in a tent pitched so near the water that it was reflected on the surface.
When Greybeard and his wife Martha and Charley Samuels rose at this time, it was to find themselves on the edge of a widening Thames dissolved in mist. The new day drew from the land a haze into which a myriad ducks scattered. As the day advanced, the mist became orange-tinted before it thinned, to reveal the duck flying overhead or sailing in convoy on the burnished water.
Before the mists cleared, wings whispering overhead suggested the gathering of an invisible host. Geese, heading for their feeding grounds, moved over with a hollow sound that contrasted with the clat of flying swans. Smaller birds flew at higher levels. There were birds of prey too, eagles and falcons that were comparative strangers to the region.
Some of these birds had travelled over vast tracts of land to feed here, from the little teal to the sheld-duck, strutting with his striking plumage through the mud. Many of the migrants had been forced here by adamant necessity: their little warm-blooded morsels of fledgelings, with a high metabolic rate to sustain, would starve to death if left without food for eight hours; so their parents had flown to more northerly latitudes, where the hours of daylight at this time of the year lingered long over the feeding grounds.
The humans were of all the living things in this region of mist and water the least bound to such natural necessities. But they, unlike the proliferating bird-life about them, had no instinctual means of determining their direction, and within three days of leaving Oxford, their journey towards the river mouth was snared in a maze of waterways.
Their way might be difficult to find, but a sense of leisure filled them, and they felt no compulsion to get out of an area so abundantly stocked with food. Herons, geese, and duck went into a series of soups and stews at which Martha excelled herself. Fish seemed to ask only to be pulled from the river.
In these activities, they had few human rivals. Those few came mostly from the north side of the flood, from the settlements that still remained outside Oxford. They saw stoats hunting again – though not in packs
– and an animal they took to be a polecat, making off through reeds with a mallard in its jaws. They saw otter and coypu and, at the place where they camped on the third night, the spoor of some sort of deer that had come down to the water’s edge to drink.
