A flicker in the corner of his eye—lamp going out? Or Farel returning? He sprang away from the rock, flushing. But there was no tramp of boots, and the lamp burned no more badly than usual.

There. A shadow in the wavering shadows—that funny-shaped rock moved. Thur stood still, barely breathing.

The rock stood up. It was a gnarled brown mannikin, some two feet tall, with what seemed to be a leather apron like a miner's about its loins. It giggled, and jumped to one side. Its black eyes glinted in the lamp glow like polished stones. It skipped over to Thur's basket, and made to put in a lump of ore.

Thur made no sudden moves. In all his time in the mines, he'd never seen a gnome so close and clear, only movements in the corners of his eyes that seemed to vanish into the walk when he made to approach them. The mannikin giggled again, and tilted its narrow chin aside in an attitude of comical inquiry.

"Good morrow, little man," Thur whispered, fascinated, hoping his voice would not startle it away again.

"Good morrow, metal-master," the kobold returned in a tinny voice. It hopped into the basket, peered over the top at Thur, and hopped out again, in quick jerky motions. Its arms and legs were thin, its toes and fingers long and splayed, with joints like the knobs of roots.

"I'm no master." Thur smiled. He hunkered down, so as to loom less threateningly, and fumbled at his belt for the leather flask his mother had filled with goat's milk before dawn. Carefully, he reached for the ateau, the wide wooden dish used for carrying out the best ore, tapped it upside down to knock out the dirt, and poured some milk into it. He shoved it invitingly toward the little creature. "You can drink. If you wish."

It giggled again, and hopped to the rim. It did not lift the vessel, but put its head down and lapped like a cat, pointed tongue flicking rapidly in and out. Its bright eyes never wavered from Thur as it drank. The milk vanished quickly. The kobold sat up, emitted a tiny but quite distinct belch, and wiped its lips with the back of one twiggy wrist. "Good!

"My mother fixes it, in case I thirst before dinner," Thur responded automatically, then felt a little idiotic. Surely he should be trying to catch the creature, not conversing with it. Squeeze it to get it to tell him where gold or silver lay, or something. Yet its wrinkled countenance, like a dried apple, made it seem venerable, not evil or menacing.

It sidled toward Thur. He tensed. Slowly, one cool knobby finger reached out and touched Thur's wrist. I should seize it now. But he couldn't, didn't want, to move. The kobold jittered across the stones, and rubbed up against the discolored vein in the rock. It oozed, seeming to melt—It's getting away!

"Master Kobold," Thur croaked desperately, "tell me, where shall I find my treasure?"

The kobold paused. Its half-lidded eyes stared directly at Thur. Its answer was a creaky chant, like the overstrained wood of a windlass lifting a heavy load. "Air and fire, metal-master, air and fire. You are earth and water. Go to the fire. Ice water will put you out. Cold earth will stop your mouth. Cold earth is good for kobolds, not for metal-masters. Grave digger, grave digger, go to the fire, and live."

It melted into the vein, leaving only a fading giggle behind. Riddles. Ask a blasted gnome a straight and simple question, and get riddles. He should have known. The cadence of its speech had infused its words with doubled meaning. Grave digger. The solemn miner, or the man who chipped out his own tomb? Meaning himself, Thur? The sweat drying on his body had chilled him to the bone. He sank shivering to his knees. His heart was laboring, and there was a roaring in his ears like Master Kunz's furnace when the bellows played. His eyes were darkening ....o, it was the lamp flame dwindling, low and weak ....ut there was plenty of oil....

Farel's voice rang painfully in his ears. "By Our Lady, the air stinks in this pocket!" And then, "Hey, boy, hey ... !"

A strong hand closed around Thur's arm, and hauled him roughly to his feet. Thur swayed dizzily. Farel swore, and pulled Thur's arm across his own neck, and began to guide him up the tunnel.

"Bad air," said Farel. "The ventilation bellows are pumping all right now. There must be a blockage somewhere in the pipe. Damn! Maybe the kobolds did it."

"I saw a kobold," said Thur. His heart was still pounding, but his vision was beginning to clear, in so far as anyone had vision in these staring shadows in the heart of the mountain.

"I hope you shied a rock at it!" said Farel.

"I fed it some milk. It seemed to like it."

"Idiot boy! For God's sake! We're trying to get rid of the vermin, not attract morel Feed it, and it'll be back with all its brethren. No wonder we're infested!"

"It was the first time I ever saw one. It seemed nice.

"Agh." Farel shook his head. "Bad air, all right, and bad dreams from it."

They reached the fork of the tunnel. The air was fresh enough here. Farel sat Thur down beside the hollow wooden tube that piped the forced air into the lower reaches of the mine. "Stay there, while I get Master Entlebuch. Are you going to be all right?"

Thur nodded. Farel hurried away. Thur could hear him shouting up the lift shaft over the creaks and groans of the wooden machinery. Thur was still chilled, and he wrapped his arms around his torso and drew up his long legs. Farel had taken the lamp. The blackness closed in.

In time Farel returned with Master Entlebuch, who held his lamp up to Thur's face and stared at him in worry. He questioned Thur about his symptoms and went back down the runnel with Farel, tapping the wooden air pipe with a stick as he went. At length, Farel came back, carrying Thur's abandoned lamp and tools.

"A piece of pipe was crushed in a rockfall. Master Entlebuch says, forget the upper tunnel today. As soon as you feel able, go join the crew on the lower face, and haul baskets for a while."

Thur nodded and rose. Farel shared flame from his lamp to rekindle Thur's. Air and fire, thought Thur. Life. He did not feel so shaky now, and he started down the lower tunnel in search of the other work crew. He was careful on the steep descending track, so as not to spill or splash his oil, and even more careful on the ladder in the vertical shaft that drove downward another thirty feet. This bottom tunnel had followed a corkscrew-twisting vein, going down, then up again. At the end he found four men, taking turns in pairs chopping at the hard rock face or sorting over the chips while catching their wind. They greeted him in tones ranging from Niklaus's habitual good cheer to Birs's melancholy grunt.

Thur loaded a basket with good chips, heaved it to his shoulder, and carried it down and up the lower tunnel to the shaft. He emptied it into a leather bucket, climbed the ladder with the basket slung over his arm, turned the windlass and raised the bucket on its rope, refilled the basket, carted it to the upper lift shaft, dumped it in the big wooden bucket, and shouted for Henzi, who raised the load out of sight. Then Thur went back for the next load, and the next, and the next, until he lost count. He was weary with work and hunger when Henzi at last lowered a bucket packed with bread, cheese, ale, and barley water, which the men at the lower face greeted with much more animation than they'd greeted Thur.

After dinner-break Farel joined them. "Master Entlebuch and I sawed out the broken pipe, and he's gone to get another length made to fit." Farel was taken into the work gang with the usual acknowledging grunts. Thur did a stint with hammer and pick on the hardest part of the tunnel face, making the rock ring and the chips fly, till his arms and back and neck ached. The smell of the mine seemed to fill his head: cold dry dust, scraped metal, hot oil, the smoke-stink of burning fat (for it was not the best oil), sweat in wool, the cheese-and-onion breath of the men.
