month before we passed through the same point in space! Another, which made a grand appearance in the western sky in March 1843, would have involved us in its tail, if we had been only a fortnight earlier at a particular place! Rather fine shaving that in the celestial economics. Now, if we consider that as many as eight comets have been observed telescopically in a single year (1846), we must see that the chance of a collision of this kind is not quite so small as to be unworthy of regard. If it be true that there are thousands of comets, all of which make periodical visits to the near neighbourhood of the sun, it must be evident that the earth, being itself not far, comparatively speaking, from that luminary, must be rather liable as otherwise to a brush from one of these wanderers; and, indeed, the wonder is, that several thousand years should have passed without, so far as we know, any one such collision having taken place.
Seeing what a highly-organised system is formed by the physical and organic arrangements upon our planet, one is apt to think that the scheme of Providence must have been framed with a provision for the complete exclusion of such accidents. To allow of the sudden undoing of all this fair scene, which it has taken thousands of years to bring out in its full proportions, seems like a wanton destruction of valuable property, and we are not disposed to believe that such a thing could be permitted. But we must at the same time remember, that our sense of what is important and consequential has a regard to the earth alone, which is but a trifling atom in the universe. Who can tell what are the limits which the Master of worlds has set to mundane calamity? And assuredly, even though a whole solar system were here and there, now and then, to be remodelled in respect of all such arrangements as have been spoken of, it could not be supposed to be a very great event in the progress of the entire scheme, seeing that astronomy has taught us to regard such systems as no more than particles in the dust-cloud or grains of sand on the sea-shore. It must, then, in sober reasoning be admitted, that our mere abhorrence of so much destruction is no guidance to our judgment on this point; and that for anything we can see of the plans of Providence, an entanglement of our globe with a comet may take place any day, with consequences incalculably damaging for the meantime, though not conclusively destructive, and perhaps necessary as a step towards an improved system of things--the bringing in of what Ben Jonson calls 'an age of better metal.'
In the frame of mind which these speculations induce--not very greatly alarmed about such extraordinary contingencies, yet not insensible to the solemnity of the thought of what may come to pass even before our living eyes--it is curious, and not necessarily unpleasant, to consider what might be the actual phenomena attending a cometary collision. We know not what comets are composed of, but are certain that they consist of some palpable matter, however diffused, for they observe the rules of motion in their revolutions round the sun. On the whole, the most plausible supposition as to their composition, is that which regards them as watery vapour or cloud, of great tenuity. How like, for example, to the doings of a cloud, is the splitting into two, which has been occasionally observed in them! Well, if they be clouds, the coming of one into contact with our earth would most likely deposit with us an immense addition to our stock of water. It would be instantaneous, or nearly so. Only think of a sudden fall of water sufficient to raise the ocean a hundred feet, and submerge all parts of the land which were less than that height above the present level of the sea! There would, of course, be a fearful abridgment of our continents; all big islands would be made little; and many littler ones would cease to be. The surviving lands would be so swept by the flood, that scarcely any of the present features would remain unchanged. All animals and movable things would be engulfed. In a few minutes, this brawling, chattering, bustling world would be stilled in universal death. What a settlement of 'questions' there! What a strike of work! What a command of Silence!
A board of bank directors was hesitating about a bill for L.100, some thinking it rather indifferent paper, others viewing it more favourably; when down comes the cometic flood, and while the manager rings his bell to see what is the matter, it enters by doors and windows, and in
