bottles. From these bottles fumes arose, mingled, and fell in stifling clouds of fleecy white. From another bottle in Pierre's hands a dense red smoke welled from a colourless liquid, crowded through the neck, wriggled through the bar of light, and sank in the darkness beneath. The darkness was uncanny, the fumes suffocating, the low hum of the furnace forcing out the shafts of light from the cracks of the imprisoning walls infernally suggestive.

Luna shivered. He was ignorant, therefore superstitious, and superstition strongly suggested the unnatural. He knew that furnaces and retorts and acids and alkalies were necessary to the refinement of gold. He feared them, yet he had used them, but he had used them where the full light of day robbed them of half their terrors. In open air acids might smoke, but drifting winds would brush away the fumes. Furnaces might glow, but their glow would be as naught in sunlight. There was no darkness in which devils could hide to pounce on him unawares, no walls to imprison him. The gold he retorted on his shovel was his, and he had no fear of the law. In the underground laboratory of Pierre the element of fear was ever present. The gold that the furnace retorted was stolen, and Luna was the thief. There were other thieves, but that did not matter to him. He stole gold from the mill. Others stole gold from the mine. It all came to Pierre and to Pierre's underground furnace. He stood in terror of the supernatural, of the law, and, most of all, of Pierre. In the darkness barred with fierce jets of light, imprisoned by walls that he could not see, cut off from the free air of open day, stifled by pungent gases that stung him, throat and eye, he felt an uncanny oppression, fear of the unknown, fear of the law, most of all fear of Pierre.

Pierre watched him through his mantle of darkness. He thrust forward his head, and a bar of light smote him across his open lips. It showed his gleaming teeth white and shut, his black moustache, his swarthy lips parted in a sardonic smile; that was all. A horrible grin on a background of inky black.

Luna shrank.

"Leave off your devil's tricks."

"Moi?"

Pierre replaced the bottle of acid on the shelf and picked up a pair of tongs. As he raised the cover of the glowing crucible a sudden transformation took place. The upper part of the laboratory blazed out fiercely, and in this light Pierre moved with gesticulating arms, the lower part of his body wholly hidden. He lifted the crucible, shook it for a moment with an oscillatory motion, then replaced it on the fire. He turned again to Luna.

"Hall ze time I mek ze explain. Hall ze time you mek ze question. Comment?"

Luna's courage was returning in the light.

"You're damned thick-headed, when it suits you, all right. Well, I'll explain. Last clean-up I brought you two pounds of amalgam if it was an ounce. All I got out of it was fifty dollars. You said that was my share. Hansen brought you a chunk of quartz from the mine. He showed it to me first. If I know gold from sulphur, there was sixty dollars in it. Hansen got five out of it."

Pierre interrupted.

"You mek mention ze name."

"There's no one to hear in this damned hell of yours."

"Non," Pierre answered. "You mek mention in zis hell. Bimby you mek mention," Pierre gave an expressive upward jerk with his thumb, then shrugged his shoulders.

"I'll look out for that," Luna answered, impatiently. "I'm after something else now. I'm getting sick of pinching the mill and bringing the stuff here for nothing. So are the rest of the boys. We ain't got no hold on you and you ain't playing fair. You've got to break even or this thing's going to stop."

Pierre made no reply to Luna. He picked up the tongs, lifted the crucible from the fire, and again replaced it. Then he brought out an ingot mould and laid it on a ledge of the furnace. The crucible was again lifted from the fire, and its contents were emptied in the mould. Pierre and Luna both watched the glowing metal. As it slowly cooled, iridescent sheens of light swept over its surface like the changing colours of a dying dolphin. Pierre held up the mould to Luna.

"How much she bin?"

Luna looked covetously at the softly glowing metal. "Two hundred."

"Bien. She's bin ze amalgam, ze quart', ze hozer stoff. Da's hall."

Luna looked sceptical.

"That's too thin. How many times have you fired up?"

"Zis!" Pierre held up a single emphasizing finger.

"We'll let that go," Luna answered; "but you listen now. One of the battery men is off to-night. I'm going to put Morrison on substitute. He's going to break a stem or something. The mortar's full to the dies. We're going to clean it out. I know how much it will pan. It's coming to you. You divide fair or it's the last you'll get. I'll hide it out in the usual place."

"Look hout! Da's hall!"

The other laughed impatiently.

"Getting scared, Frenchy? Where's your nerve?"

"Nerf! Nerf!" Pierre danced from foot to foot, waving his arms. "Sacré plastron! You mek ze fuse light. You sit on him, heh? Bimeby, pretty soon, you got no nerf. You got noddings. You got one big gris-spot on ze rock. Da's hall." Pierre subsided, with a gesture of intense disgust.

Luna snapped his watch impatiently.

"It's my shift, Frenchy. I've got to go in a few minutes."

"Bien! Go!" Pierre spoke without spirit. "Mek of yourself one gran' folie. Mais, when ze shot go, an' you sail in ze air, don' come down on ze Blue Goose, on me, Pierre. I won't bin here, da's hall."

Luna turned.

"I tell you I've got to go now. I wish you'd tell me what's the matter with the old man."

Pierre roused himself.

"Noddings. Ze hol' man has noddings ze mattaire. It is you! You! Ze hol' man, he go roun' lak he kick by ze dev'. He mek his glass eyes to shine here an' twinkle zere, an' you mek ze gran' chuckle, 'He see noddings.' He see more in one look dan you pack in your tick head! I tol' you look hout; da's hall!"

Luna jammed his watch into his pocket and rose.

"It's all right, Frenchy. I'll give you another chance. To-day's Thursday. Saturday they'll clean up at the mill. It will be a big one. I want my rake-off. The boys want theirs. It all comes to the Blue Goose, one way or another. You think you're pretty smooth stuff. That's all right; but let me tell you one thing: if there's any procession heading for Cañon City, you'll be in it, too."

Cañon City was the State hostelry. Occasionally the law selected unwilling guests. It was not over-large, nor was it overcrowded. Had it sheltered all deserving objects, the free population of the State would have been visibly diminished.

Pierre only shrugged his shoulders. He followed Luna up the stairs to the outer door, and watched the big mill foreman as he walked down the trail to the mill. Then, as was his custom when perturbed in mind, Pierre crossed the dusty waggon trail and seated himself on a boulder, leaning his back against a scrubby spruce. He let his eyes rest contentedly on a big, square-faced building. Rough stone steps led up to a broad veranda, from which rose, in barbaric splendour, great sheets of shining plate-glass, that gave an unimpeded view of a long mahogany bar backed by tiers of glasses and bottles, doubled by reflection from polished mirrors that reached to the matched-pine ceiling.

Across the room from the bar, roulette and faro tables, bright with varnish and gaudy with nickel trimmings, were waiting with invitations to feverish excitement. The room was a modern presentation of Scylla and Charybdis. Scylla, the bar, stimulated to the daring of Charybdis across the way, and Charybdis, the roulette, sent its winners to celebrate success, or its victims to deaden the pain of loss.

At the far end of the room a glass-covered arcade stood in advance of doors to private club-rooms. At the arcade an obliging attendant passed out gold and silver coins, for a
