L57-3: Back in the old country
Well, I had been wrong, for I was now lost.
I looked at the map and then at the millimeter.
I had come ten miles since leaving the town, and at this point,
according to my father,
I should be looking at farms and cottages in a valley,
with the spire of the church of our village showing in the far distance.
I could see no valley, no farms, no cottages and no church spire -- only a lake.
I decided that I must have taken a wrong turning somewhere.
So I drove back to the town and began to retrace the route,
taking frequent glances at the map.
I landed up at the same corner.
The curious thing was that the lake was not marked on the map.
I left as if I had stumbled into a nightmare country,
as you sometimes do in dreams.
And, as in a nightmare, there was nobody in sight to help me.
Fortunately for me,
as I was wondering what to do next,
there appeared on the horizon a man on horseback, riding in my direction.
I waited till he came near,
then I asked him the way to our old village.
He said that there was now no village.
I thought he must have misunderstood me,
so I repeated its name.
This time he pointed to the lake.
The village no longer existed because it had been submerged, and all the valley too. The lake was not a natural one, but a man-made reservoir.
