Tunnels 01, Tunnels

and asked in a low voice, "Excuse me, what's that thing you've got there?"
    The boy glared charily at him and muttered, "It's a pitch cleaver, of course."
    "A pitch cleaver," Will repeated. "Uh, thanks," he added as the boy deliberately slowed his pace, dropping back from him. At that point, Will felt more alone than he could ever remember and was suddenly overwhelmed by the strongest yearning to turn around and go back to the Jerome house. But he knew he had no alternative but to do what he was told down here in this place. He had to toe the line.
    Eventually they entered a tunnel, the tramping of their boots echoing around them. The tunnel walls haad diagonal veins of a shiny black rock running through them, like strata of obsidian or even, as he looked more closely, polished coal. Was that what they were on their way to do? Will's head immediately filled with images of miners stripped to the waist, crawling into narrow seams and hacking away at the dusty black coal face. His mind swam with apprehension.
    After a few minutes they crossed through into a cavern, smaller than the one they had just left. The first thing Will noticed was that the air was different in here; the humidity had increased to the point that he could feel the moisture collect on his face and mingle with his sweat. Then he noticed that the cavern walls were shored up with huge slabs of limestone. Cal had told him that the Colony was made up of an interlinking series of chambers, some naturally formed and others, like this one, man-made with partially reinforced walls.
    "I hope Dad's seen this!" Will said under his breath, longing to stop and savor his surroundings, perhaps even to do a sketch or two to record it. But he had to be content with taking in as much as he could as they tramped quickly along.
    There were fewer buildings in this cavern, giving it an almost rural feel, and a little farther on they marched by some oak-beamed barns and single-story houses like little bungalows, some freestanding but most built into the walls. As for the residents of the cavern, he saw only a handful of people carrying bulky canvas bags on their backs or pushing loaded wheelbarrows.
    The troop followed Mr. Tonypandy as he veered off the road and down into a deep trench, the bottom of which was full of sodden clay. Slippery and treacherous, it clung to their boots, hampering their progress as they weaved their way through a meandering course. Soon the trench opened into a sizable crater at the base of the cavern wall itself, and the work party drew up beside two crude stone-built structures with flat roofs. The boys seemed to know that they should just wait, leaning against their shovels and pitch cleavers as Mr. Tonypandy began a lively discussion with two older men who had emerged from one of the buildings. The boys in the troop joked and chatted noisily together, sometimes giving Will sidelong glances as he stood apart from them. Then Mr. Tonypandy left, limping off in the direction of the road, and one of the older men shouted over at Will.
    "You're with me, Jerome. Go to the huts."
    The man had a livid red scar in the shape of a crescent across his face. It began just above his mouth and ran up across his left eye and forehead, parting the man's snow-white hair and ending somewhere at the back of his head. But for Will, the man's eye, permanently weeping and shot through with a mottled cloudiness, was the most distressing aspect of his appearance. The eyelid over it was so torn and ragged that each time the man blinked, it was like a defective windshield wiper struggling to function.
    "In there! In there!" he barked as Will failed to acknowledge the order.
    "Sorry," Will answered quickly. Then he and two other youngsters followed the scar man into the nearest building.
    The interior was dank and, except for some equipment in the corner, appeared to be empty. They stood idly around as the scar man kicked at the dirt floor as if looking for something he'd lost. He began to swear wildly under his breath until his boot finally struck something solid. It was as metal ring. He pulled at it with both hands, and there was a loud creaking as a steel plate lifted to reveal an opening three feet square.
    "OK, down we go."
    One by one they filed down a wet, rusty stepladder, and once they had all reached the bottom, the scar man took the lantern from his belt and played it around the brick-lined tunnel. It wasn't quite high enough to stand up in and, judging by the
