But, an hour ago, the leaves at my window first shook slightly. They are now trembling continuously, as those of all the trees, under a gradually rising wind, of which the tremulous action scarcely permits the direction to be defined,—but which falls and returns in fits of varying force, like those which precede a thunderstorm—never wholly ceasing: the direction of its upper current is shown by a few ragged white clouds, moving fast from the north, which rose, at the time of the first leaf-shaking, behind the edge of the moors in the east.
This wind is the plague-wind of the eighth decade of years in the nineteenth century; a period which will assuredly be recognized in future meteorological history as one of phenomena hitherto unrecorded in the courses of nature, and characterized pre-eminently by the almost ceaseless action of this calamitous wind. While I have been writing these sentences, the white clouds above specified have increased to twice the size they had when I began to write; and in about two hours from this time—say by eleven o'clock, if the wind continue,—the whole sky will be dark with them, as it was yesterday, and has been through prolonged periods during the last five years. I first noticed the definite character of this wind, and of the clouds it brings with it, in the year 1871, describing it then in the July number of 'Fors Clavigera'; but little, at that time, apprehending either its universality, or any probability of its annual continuance. I am able now to state positively that its range of power extends from the North of England to Sicily; and that it blows more or less during the whole of the year, except the early autumn. This autumnal abdication is, I hope, beginning: it blew but feebly yesterday, though without intermission, from the north, making every shady place cold, while the sun was burning; its effect on the sky being only to dim the blue of it between masses of ragged cumulus. To-day it has entirely fallen; and there seems hope of bright weather, the first for me since the end of May, when I had two fine days at Aylesbury; the third, May 28th, being black again from morning to evening. There seems to be some reference to the blackness caused by the prevalence of this wind in the old French name of Bise, 'gray wind'; and, indeed, one of the darkest and bitterest days of it I ever saw was at Vevay in 1872."
The first time I recognized the clouds brought by the plague-wind as distinct in character was in walking back from Oxford, after a hard day's work, to Abingdon, in the early spring of 1871: it would take too long to give you any account this evening of the particulars which drew my attention to them; but during the following months I had too frequent opportunities of verifying my first thoughts of them, and on the first of July in that year wrote the description of them which begins the 'Fors Clavigera' of August, thus:—
"It is the first of July, and I sit down to write by the dismalest light that ever yet I wrote by; namely, the light of this midsummer morning, in mid-England, (Matlock, Derbyshire), in the year 1871.
"For the sky is covered with gray cloud;—not rain-cloud, but a dry black veil, which no ray of sunshine can pierce; partly diffused in mist, feeble mist, enough to make distant objects unintelligible, yet without any substance, or wreathing, or color of its own. And everywhere the leaves of the trees are shaking fitfully, as they do before a thunder-storm; only not violently, but enough to show the passing to and fro of a strange, bitter, blighting wind. Dismal enough, had it been the first morning of its kind that summer had sent. But during all this spring, in London, and at Oxford, through meager March, through changelessly sullen April, through despondent May, and darkened June, morning after morning has come gray-shrouded thus.
"And it is a new thing to me, and a very dreadful one. I am fifty years old, and more; and since I was five, have gleaned the best hours of my life in the sun of spring and summer mornings; and I never saw such as these, till now.
"And the scientific men are busy as ants, examining the sun, and the moon, and the seven stars, and can tell me all about them, I believe, by this time; and how they move, and what they are made of.
"And I do not care, for my part, two copper spangles how they move, nor what they are made of. I can't move them any other way than they go, nor make them of anything else, better than they are made. But I would care much and give much, if I could be told where this bitter wind comes from, and what it is made of.
"For, perhaps, with forethought, and fine laboratory science, one might make it of something else.
