"Why does he stay there?"

I explained about the volcano. "You can have no idea what an obsession it is with him. There isn't a square foot of its steaming, treacherous surface that he hasn't been over, mapping new fissures, poking into old lava-beds, delving into the crater itself on favorable days——"

"Isn't it dangerous?"

"In a way, yes. The volcano itself is harmless enough. It smokes unpleasantly now and then, splutters and rumbles as if about to obliterate all creation, but for all its bluster it only manages to spill a trickle or two of fresh lava down its sides—just tamely subsides after deluging Leavitt with a shower of cinders and ashes. But Leavitt won't leave it alone. He goes poking into the very crater, half strangling himself in its poisonous fumes, scorching the shoes off his feet, and once, I believe, he lost most of his hair and eyebrows—a narrow squeak. He throws his head back and laughs at any word of caution. To my notion, it's foolhardy to push a scientific curiosity to that extreme."

"Is it, then, just scientific curiosity?" mused Miss Stanleigh.

Something in her tone made me stop short. Her eyes had lifted to mine—almost appealingly, I fancied. Her innocence, her candor, her warm beauty, which was like a pale phosphorescence in the starlit darkness—all had their potent effect upon me in that moment. I felt impelled to a sudden burst of confidence.

"At times I wonder. I've caught a look in his eyes, when he's been down on his hands and knees, staring into some infernal vent-hole—a look that is—well, uncanny, as if he were peering into the bowels of the earth for something quite outside the conceptions of science. You might think that volcano had worked some spell over him, turned his mind. He prattles to it or storms at it as if it were a living creature. Queer, yes; and he's impressive, too, with a sort of magnetic personality that attracts and repels you violently at the same time. He's like a cake of ice dipped in alcohol and set aflame. I can't describe him. When he talks——"

"Does he talk about himself?"

I had to confess that he had told us practically not a word. He had discussed everything under heaven in his brilliant, erratic way, with a fleer of cynicism toward it all, but he had left himself out completely. He had given us Farquharson with relish, and in infinite detail, from the time the poor fellow first turned up in Muloa, put ashore by a native craft. Talking about Farquharson was second only to his delight in talking about volcanoes. And the result for me had been innumerable vivid but confused impressions of the young Englishman who had by chance invaded Leavitt's solitude and had lingered there, held by some attraction, until he sickened and died. It was like a jumbled mosaic put together again by inexpert hands.

"Did you get the impression that the two men had very much in common?"
