Volume 24 — LECTURE II.

March 11th, 1884.

It was impossible for me, this spring, to prepare, as I wished to have done, two lectures for the London Institution: but finding its members more interested in the subject chosen than I had anticipated, I enlarged my lecture at its second reading by some explanations and parentheses, partly represented, and partly farther developed, in the following notes; which led me on, however, as I arranged them, into branches of the subject untouched in the former lecture, and it seems to me of no inferior interest.

"Many years in the Hudson's Bay Company's service, I and my men became educated for Arctic work, in which I was five different times employed, in two of which expeditions we lived wholly by our own hunting and fishing for twelve months, once in a stone house (very disagreeable), and another winter in a snow hut (better), without fire of any kind to warm us. On the first of these expeditions, 1846-7, my little party, there being no officer but myself, surveyed seven hundred miles of coast of Arctic America by a sledge journey, which Parry, Ross, Bach, and Lyon had failed to accomplish, costing the country about £70,000 or £80,000 at the lowest computation. The total expense of my little party, including my own pay, was under fourteen hundred pounds sterling.

"My Arctic work has been recognized by the award of the founder's gold medal of the Royal Geographical Society (before the completion of the whole of it)."

'To the Editor of the St. James's Gazette.

'Sir,—I have been a very constant though not a scientific observer of the sky for a period of forty years; and I confess to a certain feeling of astonishment at the way in which the "recent celestial phenomena" seem to have taken the whole body of scientific observers by surprise. It would even appear that something like these extraordinary sunsets was necessary to call the attention of such observers to what has long been a source of perplexity to a variety of common folk, like sailors, farmers, and fishermen. But to such people the look of the weather, and what comes of that look, is of far more consequence than the exact amount of ozone or the depth or width of a band of the spectrum.

'Now, to all such observers, including myself, it has been plain that of late neither the look of the sky nor the character of the weather has been, as we should say, what it used to be; and those whose eyes were strong enough to look now and then toward the sun have noticed a very marked increase of what some would call a watery look about him, which might perhaps be better expressed as a white sheen or glare, at times developing into solar halo or mock suns, as noted in your paper of the 2d of October last year. A fisherman would describe it as "white and davery-like." So far as my observation goes, this appearance was only absent here for a limited period during the present summer, when we had a week or two of nearly normal weather; the summer before it was seldom absent.

'Again, those whose business or pleasure has depended on the use of wind-power have all remarked the strange persistence of hard westerly and easterly winds, the westerly ones at times partaking of an almost trade-wind-like force and character. The summer of 1882 was especially remarkable for these winds, while each stormy November has been followed by a period about mid-winter of mild calm weather with dense fog. During these strong winds in summer and early autumn the weather would remain bright and sunny, and to a landsman would be not remarkable in any way, while the barometer has been little affected by them; but it has been often observed by those employed on the water that when it ceased blowing half a gale the sky at once became overcast, with damp weather or rain. This may all seem common enough to most people; but to those accustomed to gauge the wind by the number of reefs wanted in a mainsail or foresail it was not so; and the number of consecutive days when two or more reefs have been kept tied down during the last few summers has been remarkable—alternating at times with equally persistent spells of calm and fog such as we are now passing through. Again, we have had an unusually early appearance of ice in the Atlantic, and most abnormal weather over Central Europe; while in a letter I have just received from an old hand on board a large Australian clipper, he speaks of heavy gales and big seas off that coast in almost the height of their summer.

'Now, upon all this, in our season of long twilights, we have bursting upon us some clear weather; with a display of cloud-forms or vapor at such an elevation that, looking at them one day through an opening in the nearer clouds, they seemed so distant as to resemble nothing but the delicate grain of ivory upon a billiard-ball. And yet with the fact that two-thirds of this earth is covered with water, and bearing in mind the effect which a very small increase of sun-power would have in producing cloud and lifting it above its normal level for a time, we are asked to believe that this sheen is all dust of some kind or other, in order to explain what are now known as the "recent sunsets": though I venture to think that we shall see more of them yet when the sun comes our way again.

'At first sight, increased sun-power would seem to mean more sunshine; but a little reflection would show us that this would not be for long, while any considerable addition to the sun's power would be followed by such a vast increase of vapor that we should only see him, in our latitudes, at very short intervals. I am aware that all this is most unscientific; but I have read column after column of explanation written by those who are supposed to know all about such things, and find myself not a jot the wiser for it. Do you know anybody who is?—I am, Sir, your obedient servant,

And again—

And again—

"The Recent Sunsets and Volcanic Eruptions.

"Sir,—It may, perhaps, be interesting at the present time, when so much attention has been given to the late brilliant sunsets and sunrises, to be reminded that almost identically the same appearances were observed just a hundred years ago.

Gilbert White writes in the year 1783, in his 109th letter, published in his 'Natural History of Selborne':—

'The summer of the year 1783 was an amazing and portentous one, and full of horrible phenomena; for besides the alarming meteors and tremendous thunderstorms that affrighted and distressed the different counties of this kingdom, the peculiar haze or smoky fog that prevailed for many weeks in this island and in every part of Europe, and even beyond its limits, was a most extraordinary appearance, unlike anything known within the memory of man. By my journal I find that I had noticed this strange occurrence from June 23d to July 20th inclusive, during which period the wind varied to every quarter without making any alteration in the air. The sun at noon looked as black as a clouded moon, and shed a ferruginous light on the ground and floors of rooms, but was particularly lurid and blood-colored at rising and setting. The country people began to look with a superstitious awe at the red lowering aspect of the sun; and, indeed, there was reason for the most enlightened person to be apprehensive, for all the while Calabria and part of the Isle of Sicily were torn and convulsed with earthquakes, and about that juncture a volcano sprang out of the sea on the coast of Norway.'

Other writers also mention volcanic disturbances in this same year, 1783. We are told by Lyell and Geikie, that there were great volcanic eruptions in and near Iceland. A submarine volcano burst forth in the sea, thirty miles southwest of Iceland, which ejected so much pumice that the ocean was covered with this substance, to the distance of 150 miles, and ships were considerably impeded in their course; and a new island was formed, from which fire and smoke and pumice were emitted.

Besides this submarine eruption, the volcano Skaptar-Jökull, on the mainland, on June 11th, 1783, threw out a torrent of lava, so immense as to surpass in magnitude the bulk of Mont Blanc, and ejected so vast an amount of fine dust, that the atmosphere over Iceland continued loaded with it for months afterwards. It fell in such quantities over parts of Caithness—a distance of 600 miles—as to destroy the crops, and that year is still spoken of by the inhabitants as the year of 'the ashie.'

These particulars are gathered from the text-books of Lyell and Geikie.

I am not aware whether the coincidence in time of the Icelandic eruptions, and of the peculiar appearance of the sun, described by Gilbert White, has yet been noticed; but this coincidence may very well be taken as some little evidence towards explaining the connection between the recent beautiful sunsets and the tremendous volcanic explosion of the Isle of Krakatoa in August last.
