"He'd be of the upper classes, no doubt;" added Peter Bligh; "he'll see that we don't sleep in damp sheets! Aye, 'tis the devil of a man, surely!" Doctor Gray heard them patiently--more patiently than I did--and then went on again: "If you stop here, you starve; if you go on--well, you take your luck. Should the fog lift up yonder, you'll be having Czerny back again. It's a rule-of-three sum, gentlemen. For my part, I say 'go on and take your luck,' but I won't speak for you unless you are willing." "None more willing," cried I, coming to a resolution on the spot. "Forward let it be, and luck go with us. We'd be fools to die like rats in a trap when there's light and food not a mile away. And cowards, too, boys--cowards!" I added. The others said: "Aye, aye, we're no cowards!" And all being of one mind we set out together through that home of wonders. Edmond Czerny's house we sought, and thither this iron road would carry us. A path more beautiful no man has trodden. From this time the great, church-like grottos gave place to lower roofs and often black-dark openings. By here and there we dived into tunnels wondrously cut by some forgotten river of fire in the ages long ago, and, emerging again, we entered a wilderness of ravines wherefrom even the sky was to be seen and the cliffs towering majestically above us. Then, at last, we left the daylight altogether, and going downward as to the heart of the earth I knew that the land lay behind us and that the sea flowed above our heads. Reader of a plain seaman's story, can you come with me on such a journey as I and four stout hearts made on that unforgotten day? Can you picture, as I picture now, that dark and lonesome cavern, with the sea beating upon its roof and the air coming salt and humid to the tongue, and the echo of distant breakers in your ears, and always the night and the doubt of it? Can you follow me from grotto to grotto and labyrinth to labyrinth, stumbling often by the way, catching at the lantern's dancing rays, calling one to the other, "All's well--lead on"? Aye, I doubt that you can. These things must be seen with a man's own eyes, heard with his own ears, to be understood and made real to him. To me that scene lives as though yesterday had brought it. I see the doctor with his impatient step. I see Peter Bligh stumbling after him. I hear little Dolly Venn's manly voice; I help Seth Barker over the rocks. And these four stand side by side with me on the white pool's edge. The danger comes again. The fear, the loathing, are unforgotten.
