"We accept what we saw with our eyes."
"But you accepted it as a miracle, that is to say, as a phenomenon which Maguennoc produced by special and, truth to tell, by supernatural means. Whereas I, when I read this detail in M. d'Hergemont's letter, at once-what shall I say?-caught on. I at once established the connection between those monstrous blossoms and the name borne by the Calvary of the flowers. And my conviction was immediate: 'No, Maguennoc is not a wizard. He simply cleared a piece of uncultivated land around the Calvary; and all he had to do, to produce abnormal flowers, was to bring along a layer of mould. So the God-Stone is underneath; the God-Stone which, in the middle-ages, produced the same abnormal flowers; the God-Stone, which, in the days of the Druids, healed the sick and strengthened children.'"
"Therefore," said Patrice, "there is a miracle."
"There is a miracle if we accept the supernatural explanation. There is a natural phenomenon if we look for it and if we find the physical cause capable of giving rise to the apparent miracle."
"But those physical causes don't exist! They are not present."
[Pg 364]"They exist, because you have seen monstrous flowers."
"Then there is a stone," asked Patrice, almost chaffingly, "which can naturally give health and strength? And that stone is the God-Stone?"
"There is not a particular, individual stone. But there are stones, blocks of stone, rocks, hills and mountains of rock, which contain mineral veins formed of various metals, oxides of uranium, silver, lead, copper, nickel, cobalt and so on. And among these metals are some which emit a special radiation, endowed with peculiar properties known as radioactivity. These veins are veins of pitchblende which are found hardly anywhere in Europe except in the north of Bohemia and which are worked near the little town of Joachimsthal. And those radioactive bodies are uranium, thorium, helium and chiefly, in the case which we are considering…"
"Radium," Francois interrupted.
"You've said it, my boy: radium. Phenomena of radioactivity occur more or less everywhere; and we may say that they are manifested throughout nature, as in the healing action of thermal springs. But plainly radioactive bodies like radium possess more definite properties. For instance, there is no doubt that the rays and the emanation of radium exercise a power over the life of plants, a power similar to that caused by the passage of an electric current. In both cases, the stimulation of the nutritive centres makes the elements required by the plant more easy to assimilate and promotes its growth. In the same way, there is no doubt that the radium rays are capable of exercising a physiological action[Pg 365] on living tissues, by producing more or less profound modifications, destroying certain cells and contributing to develop other cells and even to control their evolution. Radiotherapy claims to have healed or improved numerous cases of rheumatism of the joints, nervous troubles, ulceration, eczema, tumours and adhesive cicatrices. In short radium is a really effective therapeutic agent."
"So," said Stephane, "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," Stephane 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."
[Pg 366]Stephane 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 hell-fire and 'gives life or death,' he chopped off his hand."
"Very well," said Stephane, "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, Stephane! I am glad to see that Francois' friend and tutor has a far-seeing 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 Francois? 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!"
[Pg 368]"You're right, Francois, 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 to-day 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 Veronique, "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."
