Therefore it is that we call coal "black diamonds."

Ivan Behrend, the owner of the Bondavara coal-mine, was not exactly in the condition of some of his pitmen. He had seen God's heaven, and knew how in happier lands life was bright, careless, sunny as the cloudless sky itself. But for an existence which was all play and no work, Ivan would not have cared. He had inherited the coal-mine from his father, who had left him also an inheritance of a strong will and inflexible perseverance. No trifle, nor even a great obstacle, could stand in the way of Ivan's wishes, and his wish and his pride was to work the Bondavara mine without any help but what his pitmen gave him. It was his ambition—perhaps a foolish one—to have no company at his back, no shareholders to find fault, no widows and orphans to be involved in possible ruin; the mine was his, and his it should be absolutely. Therefore it was a quiet business. The foundry and the inhabitants of the nearest town consumed the yearly output at an uncommonly low price. It never could be, unless with enormous outlay, a great money-making business, seeing that the mine was too far away from any of the great centres. Nevertheless, it brought in a steady income, especially as Ivan paid no useless expenses, and was, as we have said, his own overseer and accountant. He knew everything that went on, he understood his own business perfectly, and he took a pleasure in looking after his own affairs; and these three qualifications, as any business man knows, insure ultimate success.

It was well, however, that he enjoyed such good health, and that this superabundance of vital energy kept him always occupied, and, by a natural consequence, never dull. There was no denying that it was a solitary life for so young a man.

Ivan was very little over thirty, and when he opened the door of his small house with his key, and closed the door behind him, he was alone. He hadn't even a dog to come and greet him. He waited upon himself; and in this he was a great man. Eating he looked upon as an unnecessary waste of time; nevertheless, he ate a great deal, for his muscular and mental system needed food. He was not delicate in his appetite. He dined every day at the tavern. His food was very little better than that of his pitmen, the only difference being that he avoided the strong drinks they indulged in—for this reason, that they worked only with their bodies; he had to bring to his work a clear intellect, not a soddened one. His bed needed no making. It was a wooden plank, upon which a mattress was placed, covered with a sheep-skin. There was no use in brushing his clothes; they were always permeated with coal-dust.

Any one who would offer, by way of doing him a service, to clear out his room, would, in fact, have done him a deadly injury. It was full of every sort of thing—new books half cut, minerals, scientific instruments, plans, pictures, retorts. Not one of these should be moved from its place. There was order in the disorder, and in the heterogeneous mass Ivan could find what he wanted. In one corner was Lavoisier's pyrometer; in another Berard's gas food-warmer. Over there a wonderful sun-telescope; against the wall Bunsen's galvanic battery, together with every conceivable invention, every sort of chemical apparatus for analyzing and searching into the mysteries of Nature.

Amongst these things Ivan was wont to spend the long nights. Another man, tired as he must have been with his day's work, would have flung himself upon his bed, and have sought in sleep some compensation for the labors of the day, or if not weary enough for this, would have sat before his door and breathed the fresh air, which at night was free from smoke and coal-dust. But this student of the unseen withdrew into his inner chamber, lit his fire, made his lamp blaze, and busied himself breaking lumps of coal, cooking seeds, developing deadly gases, a breath of which was enough to send a man into eternity.

What was it he searched for? Was he seeking the secret of the philosopher's stone? Did he abandon sleep to find out how diamonds can be made out of coal? Did he strive to extract deadly poisons, or was he simply pursuing the ignis fatuus of knowledge—trying experiments, grubbing in the dark until, in the hopeless endeavor, the over-strained brain would give way, and there would be only the wreck of what was once a noble intellect?

Nothing of the sort. This man had a purpose; he wanted to learn a secret which would be of infinite benefit to mankind—at least, to those who are buried in the pits and caverns of the earth. He wanted to find out by what means it would be possible to extinguish fire in burning pits. To discover this he consumed his nights and the years of his youth and his manhood. It was no thought born of to-day or yesterday; it had been his one desire for many years. He had seen so much misery, such heartrending scenes enacted before these pit mouths—these monsters which swallow up human life like the Juggernauts of old. He wanted to prevent this amount of sacrifice—a sacrifice never thought of by those who profit from the labor of these victims, whose very blood is spilled to keep others warm. It is possible this one idea might drive him mad, or he might lose his life; but the knowledge, if he did gain it, would be, in his opinion, worth the loss. After all, what is the loss of one life against the saving of millions? This man had a fine nature; there was no tinge of self in Ivan Behrend. Also, he had a certain enjoyment in his search. Enjoyment is not the word. Whenever he got even a glimpse of what he wanted, his joy was something unearthly. Surely these moments were worth all the pleasures the world could offer him; and if we can bring our minds to understand this, then we shall comprehend how a young man preferred to be shut up in a cavern, in danger of losing his life, or in a stifling room, trying risky experiments, rather than spend the night with beautiful maidens or pleasant fellows, drinking, dancing, and love-making. There is a charm in Science to those who know her that far surpasses carnal joys.

To-night, however, it must be confessed, Ivan's experiments fell a little flat. Either he was tired, or some other cause was at work. Could it be possible that a girl's song— Yes, such was the humiliating condition of affairs. At the moment when he least expected it, this thing had unexpectedly seized upon him.

With an effort Ivan lit his lamp and lighted his furnace. His experiments, however, were a failure. That girl's song kept running in his head, and the words—how did they go?
