Camilla: You, sir, should unmask.
          Stranger: Indeed?
          Cassilda: Indeed it's time. We all have laid aside disguise but you.
          Stranger: I wear no mask.
          Camilla: (Terrified, aside to Cassilda.) No mask? No mask!

          —The King in Yellow, Act I, Scene 2.

Although I knew nothing of chemistry, I listened fascinated. He picked up an Easter lily which Geneviève had brought that morning from Notre Dame, and dropped it into the basin. Instantly the liquid lost its crystalline clearness. For a second the lily was enveloped in a milk-white foam, which disappeared, leaving the fluid opalescent. Changing tints of orange and crimson played over the surface, and then what seemed to be a ray of pure sunlight struck through from the bottom where the lily was resting. At the same instant he plunged his hand into the basin and drew out the flower. "There is no danger," he explained, "if you choose the right moment. That golden ray is the signal."

He held the lily toward me, and I took it in my hand. It had turned to stone, to the purest marble.

"You see," he said, "it is without a flaw. What sculptor could reproduce it?"

The marble was white as snow, but in its depths the veins of the lily were tinged with palest azure, and a faint flush lingered deep in its heart.

"Don't ask me the reason of that," he smiled, noticing my wonder. "I have no idea why the veins and heart are tinted, but they always are. Yesterday I tried one of Geneviève's gold-fish,—there it is."

The fish looked as if sculptured in marble. But if you held it to the light the stone was beautifully veined with a faint blue, and from somewhere within came a rosy light like the tint which slumbers in an opal. I looked into the basin. Once more it seemed filled with clearest crystal.

"If I should touch it now?" I demanded.

"I don't know," he replied, "but you had better not try."

"There is one thing I'm curious about," I said, "and that is where the ray of sunlight came from."

"It looked like a sunbeam true enough," he said. "I don't know, it always comes when I immerse any living thing. Perhaps," he continued, smiling, "perhaps it is the vital spark of the creature escaping to the source from whence it came."

I saw he was mocking, and threatened him with a mahl-stick, but he only laughed and changed the subject.

"Stay to lunch. Geneviève will be here directly."

"I saw her going to early mass," I said, "and she looked as fresh and sweet as that lily—before you destroyed it."

"Do you think I destroyed it?" said Boris gravely.

"Destroyed, preserved, how can we tell?"

We sat in the corner of a studio near his unfinished group of the "Fates." He leaned back on the sofa, twirling a sculptor's chisel and squinting at his work.

"By the way," he said, "I have finished pointing up that old academic Ariadne, and I suppose it will have to go to the Salon. It's all I have ready this year, but after the success the 'Madonna' brought me I feel ashamed to send a thing like that."

The "Madonna," an exquisite marble for which Geneviève had sat, had been the sensation of last year's Salon. I looked at the Ariadne. It was a magnificent piece of technical work, but I agreed with Boris that the world would expect something better of him than that. Still, it was impossible now to think of finishing in time for the Salon that splendid terrible group half shrouded in the marble behind me. The "Fates" would have to wait.

We were proud of Boris Yvain. We claimed him and he claimed us on the strength of his having been born in America, although his father was French and his mother was a Russian. Every one in the Beaux Arts called him Boris. And yet there were only two of us whom he addressed in the same familiar way—Jack Scott and myself.

Perhaps my being in love with Geneviève had something to do with his affection for me. Not that it had ever been acknowledged between us. But after all was settled, and she had told me with tears in her eyes that it was Boris whom she loved, I went over to his house and congratulated him. The perfect cordiality of that interview did not deceive either of us, I always believed, although to one at least it was a great comfort. I do not think he and Geneviève ever spoke of the matter together, but Boris knew.

Geneviève was lovely. The Madonna-like purity of her face might have been inspired by the Sanctus in Gounod's Mass. But I was always glad when she changed that mood for what we called her "April Manœuvres." She was often as variable as an April day. In the morning grave, dignified and sweet, at noon laughing, capricious, at evening whatever one least expected. I preferred her so rather than in that Madonna-like tranquillity which stirred the depths of my heart. I was dreaming of Geneviève when he spoke again.

"What do you think of my discovery, Alec?"

"I think it wonderful."

"I shall make no use of it, you know, beyond satisfying my own curiosity so far as may be, and the secret will die with me."

"It would be rather a blow to sculpture, would it not? We painters lose more than we ever gain by photography."

Boris nodded, playing with the edge of the chisel.

"This new vicious discovery would corrupt the world of art. No, I shall never confide the secret to any one," he said slowly.

It would be hard to find any one less informed about such phenomena than myself; but of course I had heard of mineral springs so saturated with silica that the leaves and twigs which fell into them were turned to stone after a time. I dimly comprehended the process, how the silica replaced the vegetable matter, atom by atom, and the result was a duplicate of the object in stone. This, I confess, had never interested me greatly, and as for the ancient fossils thus produced, they disgusted me. Boris, it appeared, feeling curiosity instead of repugnance, had investigated the subject, and had accidentally stumbled on a solution which, attacking the immersed object with a ferocity unheard of, in a second did the work of years. This was all I could make out of the strange story he had just been telling me. He spoke again after a long silence.

"I am almost frightened when I think what I have found. Scientists would go mad over the discovery. It was so simple too; it discovered itself. When I think of that formula, and that new element precipitated in metallic scales—"

"What new element?"

"Oh, I haven't thought of naming it, and I don't believe I ever shall. There are enough precious metals now in the world to cut throats over."

I pricked up my ears. "Have you struck gold, Boris?"

"No, better;—but see here, Alec!" he laughed, starting up. "You and I have all we need in this world. Ah! how sinister and covetous you look already!" I laughed too, and told him I was devoured by the desire for gold, and we had better talk of something else; so when Geneviève came in shortly after, we had turned our backs on alchemy.

Geneviève was dressed in silvery grey from head to foot. The light glinted along the soft curves of her fair hair as she turned her cheek to Boris; then she saw me and returned my greeting. She had never before failed to blow me a kiss from the tips of her white fingers, and I promptly complained of the omission. She smiled and held out her hand, which dropped almost before it had touched mine; then she said, looking at Boris—

"You must ask Alec to stay for luncheon." This also was something new. She had always asked me herself until to-day.

"I did," said Boris shortly.

"And you said yes, I hope?" She turned to me with a charming conventional smile. I might have been an acquaintance of the day before yesterday. I made her a low bow. "J'avais bien l'honneur, madame," but refusing to take up our usual bantering tone, she murmured a hospitable commonplace and disappeared. Boris and I looked at one another.

"I had better go home, don't you think?" I asked.

"Hanged if I know," he replied frankly.

While we were discussing the advisability of my departure Geneviève reappeared in the doorway without her bonnet. She was wonderfully beautiful, but her colour was too deep and her lovely eyes were too bright. She came straight up to me and took my arm.

"Luncheon is ready. Was I cross, Alec? I thought I had a headache, but I haven't. Come here, Boris;" and she slipped her other arm through his. "Alec knows that after you there is no one in the world whom I like as well as I like him, so if he sometimes feels snubbed it won't hurt him."

"À la bonheur!" I cried, "who says there are no thunderstorms in April?"

"Are you ready?" chanted Boris. "Aye ready;" and arm-in-arm we raced into the dining-room, scandalizing the servants. After all we were not so much to blame; Geneviève was eighteen, Boris was twenty-three, and I not quite twenty-one.
