The old man spoke. His voice was a hoarse, exhausted croak, worn out from decades of over-use; mucus ground deep in his chest like gravel whipped by an estuarine tide.
‘I remember when all this used to be farmland.’ He let the statement sink, settle itself, a heavy log tossed into a morass.
He waited. There was no response from the boy. The winch rattled as whoever it was finished drawing water from the well; warblers shrilled as they whipped across the salt marsh, searching for insects.
The old man wanted a response from the boy. He waited, thinking about making his statement again.
The boy piped up. ‘Look at this, Grandad. Look!’
Pondering, the old man made his way over to where the boy crouched, at the edge of the water. Holding the reed in a firm grasp, the boy was sweeping it backwards and forwards through the shallows, stirring up a current that made the drowned grass-stems swirl and gesture in limp pirouettes.
The boy was excited. ‘Look, Grandad, look, they’re waving, wave back!’ He stirred the water again, waited while the grass-stems settled into place again, like the head-hairs on a drowned body.
‘Grandad, what’s that?’ The boy pointed with the reed, poking down amid the grass-roots.
‘What’s what?’ The old man saw nothing.
‘Those…thingys!’ The boy’s powers of description failed him; he pointed.
The old man craned closer. Amid the grass-stems he now made out movement, the infinitesimal agitation of something, like tiny wings beating. He saw that there were many of them, now another, and another; beneath the water’s surface, tiny, translucent, shrimp-like things, moving like ticks amid the dead hairs of the grass. They were living in the salt fen, feeding on whatever invisible life clung on amid the shrivelling stems of the drowned embankment.
The boy was looking up at him, wondering, wanting an answer, his small face pursed against the shrill breeze that came in from the sea. ‘Grandad, what are they?’
The old man pondered for a moment, still looking in surprise and puzzlement at the mite-like organisms that flickered and flourished beneath the surface of the water. Then he gave up.
‘I don’t know’, he said.
