To a wider intelligence it may well seem of very great possible importance--so great as to involve the ultimate welfare of every man, woman, and child upon this planet. I can hardly hope, by the use of scientific language, to convey any sense of my meaning to those ineffectual people who gather their ideas from the columns of a daily newspaper. I will endeavour, therefore, to condescend to their limitation and to indicate the situation by the use of a homely analogy which will be within the limits of the intelligence of your readers."
"Man, he's a wonder--a living wonder!" said McArdle, shaking his head reflectively. "He'd put up the feathers of a sucking-dove and set up a riot in a Quakers' meeting. No wonder he has made London too hot for him. It's a peety, Mr. Malone, for it's a grand brain! We'll let's have the analogy."
"We will suppose," I read, "that a small bundle of connected corks was launched in a sluggish current upon a voyage across the Atlantic. The corks drift slowly on from day to day with the same conditions all round them. If the corks were sentient we could imagine that they would consider these conditions to be permanent and assured. But we, with our superior knowledge, know that many things might happen to surprise the corks. They might possibly float up against a ship, or a sleeping whale, or become entangled in seaweed. In any case, their voyage would probably end by their being thrown up on the rocky coast of Labrador. But what could they know of all this while they drifted so gently day by day in what they thought was a limitless and homogeneous ocean?
Your readers will possibly comprehend that the Atlantic, in this parable, stands for the mighty ocean of ether through which we drift and that the bunch of corks represents the little and obscure planetary system to which we belong. A third-rate sun, with its rag tag and bobtail of insignificant satellites, we float under the same daily conditions towards some unknown end, some squalid catastrophe which will overwhelm us at the ultimate confines of space, where we are swept over an etheric Niagara or dashed upon some unthinkable Labrador. I see no room here for the shallow and ignorant optimism of your correspondent, Mr. James Wilson MacPhail, but many reasons why we should watch with a very close and interested attention every indication of change in those cosmic surroundings upon which our own ultimate fate may depend."
"Man, he'd have made a grand meenister," said McArdle. "It just booms like an organ. Let's get doun to what it is that's troubling him."
The general blurring and shifting of Fraunhofer's lines of the spectrum point, in my opinion, to a widespread cosmic change of a subtle and singular character. Light from a planet is the reflected light of the sun. Light from a star is a self-produced light. But the spectra both from planets and stars have, in this instance, all undergone the same change. Is it, then, a change in those planets and stars? To me such an idea is inconceivable. What common change could simultaneously come upon them all? Is it a change in our own atmosphere? It is possible, but in the highest degree improbable, since we see no signs of it around us, and chemical analysis has failed to reveal it. What, then, is the third possibility? That it may be a change in the conducting medium, in that infinitely fine ether which extends from star to star and pervades the whole universe. Deep in that ocean we are floating upon a slow current. Might that current not drift us into belts of ether which are novel and have properties of which we have never conceived? There is a change somewhere. This cosmic disturbance of the spectrum proves it. It may be a good change. It may be an evil one. It may be a neutral one. We do not know. Shallow observers may treat the matter as one which can be disregarded, but one who like myself is possessed of the deeper intelligence of the true philosopher will understand that the possibilities of the universe are incalculable and that the wisest man is he who holds himself ready for the unexpected.
