36. Blanch the Sun

(6.) And now I come to the most important sign of the plague-wind and the plague-cloud: that in bringing on their peculiar darkness, they blanch the sun instead of reddening it. And here I must note briefly to you the uselessness of observation by instruments, or machines, instead of eyes. In the first year when I had begun to notice the specialty of the plague-wind, I went of course to the Oxford observatory to consult its registrars. They have their anemometer always on the twirl, and can tell you the force, or atleast the pace, of a gale, by day or night. But the anemometer can only record for you how often it has been driven round, not at all whether it went round steadily, or went round trembling. And on that point depends the entire question whether it is a plague breeze or a healthy one: and what’s the use of telling you whether the wind’s strong or not, when it can’t tell you whether it’s a strong medicine, or a strong poison?

But again—you have your sun-measure, and can tell exactly at any moment how strong, or how weak, or how wanting, the sun is. But the sun-measurer can’t tell you whether the rays are stopped by a dense shallow cloud, or a thin deep one. In healthy weather, the sun is hidden behind a cloud, as it is behind a tree; and, when the cloud is past, it comes out again, as bright as before. But in plague-wind, the sun is choked out of the whole heaven, all day long, by a cloud which may be a thousand miles square and five miles deep.

And yet observe: that thin, scraggy, filthy, mangy, miserable cloud, for all the depth of it, can’t turn the sun red, as a good, business-like fog does with a hundred feet or so of itself. By the plague-wind every breath of air you draw is polluted, half round the world; in a London fog the air itself is pure, though you choose to mix up dirt with it, and choke yourself with your own nastiness.
