It should be possible to build a pagoda of crispbread, to think of nothing, to hear no thunder, no rain, no splashing from the gutter, no gurgling around the house. Perhaps no pagoda will emerge, but the night will pass.

Somewhere a tapping on metal.

It is always with the fourth floor that the wobbling begins; a trembling hand as the next piece of crispbread is put in place, a cough when the gable is already standing, and the whole thing lies in ruins—

Geiser has time to spare.

The news in the village is conflicting; some people say there has been no landslide at all, others that an old supporting wall has collapsed, and there is no way of diverting the highway at that spot. The woman in the post office, who ought to know, merely confirms that the mail bus is not running, but she stands behind the little counter in her usual care-laden fashion, keeping usual office hours, selling stamps, and even accepting parcels, which she places unhurriedly on the scales and then franks. It is taken for granted that state and canton are doing everything in their power to get the highway back in order. If necessary, helicopters can be brought in, unless there is fog. Nobody in the village thinks that the day, or perhaps the night, will come when the whole mountain could begin to slide, burying the village for all time.

Somewhere a tapping on metal.

It is midnight, but still no pagoda.

It started on the Thursday of the previous week, when it was still possible to sit out in the open; the weather was sultry, as always before a thunderstorm, the gnats biting through one's socks; no summer lightning, it just felt uncomfortable. Not a bird in the grounds. His guests, a youngish couple on their way to Italy, suddenly decided to leave, though they could have spent the night in his house. It was not actually cloudy—just a yellowish haze, such as one sees in the Arabian desert before a sandstorm; no wind. Faces also looking yellowish. His guests did not even empty their glasses, they were suddenly in such a hurry to be off, though there were no sounds of thunder. Not a drop of rain, either. But on the following morning it was drumming on the windowpanes, hissing through the leaves of the chestnut tree.

Since then, not a night without thunderstorms and cloudbursts.

From time to time the power is cut, something one is used to in this valley; hardly has there been time to find a candle, and then at last some matches, when the power is restored, lights in the house, though the thunder continues.

It is not so much the bad weather—

The twelve-volume encyclopedia DER GROSSE BROCKHAUS explains what causes lightning and distinguishes streak lightning, ball lightning, bead lightning, etc., but there is little to be learned about thunder; yet in the course of a single night, unable to sleep, one can distinguish at least nine types of thunder:

1.
The simple thunder crack.

2.
Stuttering or tottering thunder: this usually comes after a lengthy silence, spreads across the whole valley, and can go on for minutes on end.

3.
Echo thunder: shrill as a hammer striking on loose metal and setting up a whirring, fluttering echo which is louder than the peal itself.

4.
Roll or bump thunder: relatively unfrightening, for it is reminiscent of rolling barrels bumping against one another.

5.
Drum thunder.

6.
Hissing or gravel thunder: this begins with a hiss, like a truck tipping a load of wet gravel, and ends with a thud.

7.
Bowling-pin thunder: like a bowling pin that, struck by the rolling ball, cannons into the other pins and knocks them all down; this causes a confused echo throughout the valley.

8.
Hesitant or tittering thunder (no flash of lightning through the windows): this indicates that the storm is retreating over the mountains.

9.
Blast thunder (immediately following a flash of lightning through the windows): this is not like two hard masses colliding; on the contrary, it is like a single huge mass being blasted apart and falling to either side, breaking into countless pieces; in its wake, rain comes pouring down.

At intervals the power goes off again.

What would be bad would be losing one's memory—

An example of something Geiser has not forgotten: the Pythagorean theorem. For that he does not need to drag out the encyclopedia. On the other hand, he cannot remember how to draw the golden section (A is to B as A + B to A; that he does still know) with compasses and set square. He knew once, of course—

No knowledge without memory.

Today is Tuesday.
