“So,” said Stéphane, “you regard the God-Stone …”
“I regard the God-Stone as a block of radiferous pitchblende originating from the Joachimsthal lodes. I have long known the Bohemian legend which speaks of a miraculous stone that was once removed from the side of a hill; and, when I was travelling in Bohemia, I saw the hole left by the stone. It corresponds pretty accurately with the dimensions of the God-Stone.”
“But,” Stéphane objected, “radium is contained in rocks only in the form of infinitesimal particles. Remember that, after a mass of fourteen hundred tons of rock have been duly mined and washed and treated, there remains at the end of it all only a filtrate of some fifteen grains of radium. And you attribute a miraculous power to the God-Stone, which weighs two tons at most!”
“But it evidently contains radium in appreciable quantities. Nature has not pledged herself to be always niggardly and invariably to dilute the radium. She was pleased to accumulate in the God-Stone a generous supply which enabled it to produce the apparently extraordinary phenomena which we know of … not forgetting that we have to allow for popular exaggeration.”
Stéphane seemed to be yielding to conviction. Nevertheless he said:
“One last point. Apart from the God-Stone, there was the little chip of stone which Maguennoc found in the leaden sceptre, the prolonged touch of which burnt his hand. According to you, this was a particle of radium?”
“Undoubtedly. And it is this perhaps that most clearly reveals the presence and the power of radium in all this adventure. When Henri Becquerel, the great physicist, kept a tube containing a salt of radium in his waistcoat-pocket, his skin became covered in a few days with suppurating ulcers. Curie repeated the experiment, with the same result. Maguennoc’s case was more serious, because he held the particle of radium in his hand. A wound formed which had a cancerous appearance. Scared by all that he knew and all that he himself had said about the miraculous stone which burns like hellfire and ‘gives life or death,’ he chopped off his hand.”
“Very well,” said Stéphane, “but where did that particle of pure radium come from? It can’t have been a chip of the God-Stone, because, once again, however rich a mineral may be, radium is incorporated in it, not in isolated grains, but in a soluble form, which has to be dissolved and afterwards collected, by a series of mechanical operations, into a solution rich enough to enable successive crystallizations and concentrations to isolate the active product which the solution contains. All this and a number of other later operations demand an enormous plant, with workshops, laboratories, expert chemists, in short, a very different state of civilization, you must admit, from the state of barbarism in which our ancestors the Celts were immersed.”
Don Luis smiled and tapped the young man on the shoulder:
“Hear, hear, Stéphane! I am glad to see that François’ friend and tutor has a farseeing and logical mind. The objection is perfectly valid and suggested itself to me at once. I might reply by putting forward some quite legitimate theory, I might presume a natural means of isolating radium and imagine that, in a geological fault occurring in the granite, at the bottom of a big pocket containing radiferous ore, a fissure has opened through which the waters of the river slowly trickle, carrying with them infinitesimal quantities of radium; that the waters so charged flow for a long time in a narrow channel, combine again, become concentrated and, after centuries upon centuries, filter through in little drops, which evaporate at once, and form at the point of emergence a tiny stalactite, exceedingly rich in radium, the tip of which is broken off one day by some Gallic warrior. But is there any need to seek so far and to have recourse to hypotheses? Cannot we rely on the unaided genius and the inexhaustible resources of nature? Does it call for a more wonderful effort on her part to evolve by her own methods a particle of pure radium than to make a cherry ripen or to make this rose bloom … or to give life to our delightful All’s Well? What do you say, young François? Do we agree?”
“We always agree,” replied the boy.
“So you don’t unduly regret the miracle of the God-Stone?”
“Why, the miracle still exists!”
“You’re right, François, it still exists and a hundred times more beautiful and dazzling than before. Science does not kill miracles: it purifies them and ennobles them. What was that crafty, capricious, wicked, incomprehensible little power attached to the tip of a magic wand and acting at random, according to the ignorant fancy of a barbarian chief or Druid, what was it, I ask you, beside the beneficent, logical, reliable and quite as miraculous power which we behold today in a pinch of radium?”
Don Luis suddenly interrupted himself and began to laugh:
“Come, come, I’m allowing myself to be carried away and singing an ode to science! Forgive me, madame,” he added, rising and going up to Véronique, “and tell me that I have not bored you too much with my explanations. I haven’t, have I? Not too much? Besides, it’s finished … or nearly finished. There is only one more point to make clear, one decision to take.”
He sat down beside her:
“It’s this. Now that we have won the God-Stone, in other words, an actual treasure, what are we going to do with it?”
Véronique spoke with a heartfelt impulse:
“Oh, as to that, don’t let us speak of
