Science has discovered the existence of that incalculable energy, the ether, interpenetrated in the atmosphere. Electro-magnetic currents of power beyond all conception are revealed, and when intelligently recognized by some happy genius, like that of Marconi, they begin to be utilized in the service of human progress. Now as this ethereal energy which is only just beginning to be recognized can be drawn upon for light, for heat, for motor power, for communication, just as this hitherto undreamed-of power can be drawn upon for the fundamental needs of the physical world, so, correspondingly, does there exist the infinite reservoir of spiritual energy which God freely opens to man in precisely the proportion in which he recognizes and avails himself of its transforming power. And in this realm lies the Life Radiant. If this transfiguration of life could only be experienced by the aid of wealth and health and all for which these two factors stand, it would not be worth talking about. We hear a great deal of the "privileged classes" and of "fortunate conditions," as if there were certain arbitrary divisions in life defined by impassable boundaries, and that he who finds himself in one, is unable to pass to another.
Never was there a more fatally erroneous conception. In the spiritual world there are no limits, no boundaries, no arbitrary divisions. Just so far as the soul conquers, is it free. Conquer ignorance, and one enters the realm of education, of culture; conquer vice, and he enters into the realm of virtue; conquer impatience and irritability and bitterness, and their result in gloom and despondency, and he enters into the realm of serenity and sweetness and exaltation with their result in power of accomplishment. The Life Radiant can be achieved, and is within the personal choice of every individual. One may place himself in relation with this infinite and all-potent current of divine energy and receive its impetus and its exhilaration and its illumination every hour in the day. The toiler in manual labor may lead this two-fold life. On the visible side he is pushing onward in the excavation of a tunnel; he is laying the track of a new railroad; he is engaged in building a house; he stands at his appointed place in a great factory,—but is this all? His real work lies both in the visible and in the invisible. On the one hand he is contributing to the material resources of the world, and he is earning his wage by which to live; on the other hand he is developing patience, faithfulness, and judgment,—quantities of the spiritual man and possessions of the spiritual life which extend the spiritual territory. Faithfulness to the immediate duty creates a larger theatre for duty. There are not wanting examples that could be named of statesmen,—senators, governors, and others in high places, to say nothing of the supreme example of a Lincoln; there are not wanting examples of professional men in high and important places who initiated their work by any humble and honest industrial employment that chanced to present itself at the moment. Conquering this rudimentary realm, they passed on to others successively. Integrity is a spiritual quantity, and it insures spiritual aid. The cloud of witnesses is never dispersed. The only imprisonment is in limitations, and limitations can be constantly overcome. The horizon line of the impossible recedes as we advance. In the last analysis nothing is too sublime or too beautiful to be entirely possible. Its attainment is simply a question of conditions. These conditions lie in entering into this inner realm of spiritual energy in which the personal will is increasingly identified with the will of God.
Like an echo of celestial music are these lines by Sully-Prudhomme:—
"The lilies fade with the dying hours,
Hushed is the song-bird's lay;
But I dream of summers and dream of flowers
That last alway."
Nor is this only the day-dream of a poet. The summers and flowers that last alway are a very immediate treasure which one has only to perceive, to grasp, to recognize, and to realize. "Surely," exclaimed the Psalmist, "goodness and mercy shall follow me all the days of my life, and I shall dwell in the house of the Lord forever." This dwelling in "the house of the Lord" is by no means a figure of speech. Nor is it to be regarded as some ineffable privilege to be—possibly to be—enjoyed after that change we call death. Its real significance is here and now. One must dwell in "the house of the Lord" to-day, and every day. The "house of the Lord" is a beautiful figurative expression for that spiritual atmosphere in which one may perpetually live, and in which it is his simple duty both to live and to radiate to all around him.
In these summer days of 1903, in this golden dawn of the twentieth century, the world is echoing with wonder in the discovery of a new and most mysterious force in nature,—radium. Science is, at this date, powerless to analyze or explain its marvellous power. The leading scientists of the world of learning—Sir William Crookes, Sir Oliver Lodge, and Professor Curie (who, with Mme. Curie, has the honor of being its discoverer)—believe that in radium will be found the true solution of the problem of matter. Radium gives off rays at the speed of one hundred and twenty thousand miles a second, and these rays offer the most extraordinary heat, light, and power. Yet with this immense radiation it suffers no diminution of energy; nor can any scientist yet discern from what source this power is fed. A grain of it will furnish enough light to enable one to read, and, as Professor J. J. Thomson has observed, it will suffer no diminution in a million years. It will burn the flesh through a metal box and through clothing, but without burning the texture of the garments. The rays given out by radium cannot be refracted, polarized, or regularly reflected in the way of ordinary light, although some of them can be turned aside by a magnet.
Professor Curie has reported to the French Academy of Science that half a pound of radium salts will in one hour produce a heat equal to the burning of one-third of a foot of hydrogen gas. This takes place, it must be remembered, without any perceptible diminution in the radium. It emits heat maintaining a temperature of 2.7 degrees Fahrenheit above its surroundings. It evolves sufficient heat to melt more than its own weight of ice every hour. Radium projects its rays through solid substances without any perceptible hindrance and burns blisters through a steel case. The light is pale blue. Down in the deepest pitchblende mines, where particles of radium have been hidden away since the creation of the world, they are still found shining with their strange blue light. The radium electrons pass through the space which separates every molecule in a solid body from another. The scientific theory is that no two molecules in any body, however dense, actually touch. The relative power of radium to the X-ray is as six to one. The rays of radium have one hundred thousand times the energy of those of uranium and over one hundred times the energy of barium radiation. The scarcity of the metal will be understood when it is stated that there is far less radium in pitchblende than gold in ordinary sea water. Radium colors glass violet; transforms oxygen into ozone, white phosphorus to red; electrifies various gases and liquids, including petroleum and liquid air.
Professor Sir William Crookes, the world's greatest living physicist and experimental scientist, said of radium in the June of this 1903:—
"In total darkness I laid a piece of pitchblende—the ore from which radium is extracted—face down upon a sensitized plate, and let it act with its own light for twenty-four hours. The result was a photograph, where the black pitchblende appeared light owing to the emanations from the radium contained in it. The photograph also shows these going off into space from the sides of the specimen.
"Radium is dangerous to handle. Once I carried a tiny piece of radium in my waistcoat pocket to a soirée at the Royal Society, and on reaching home found a blister in my side. The blisters from radium may take months to get well, as the injurious effect goes so deep. Now I carry a thick lead box just large enough to hold the little brass case in which I keep the radium itself. There it lies—a little, tawny, crystalline patch. There would hardly be a larger quantity together in one box anywhere in England.
