ust (Silo, #3)(4)

“Ye gods,” Dawson grumbled, crowding noisily beside them. “What’re we to do with this?”

“Yeah, Jules,” Raph whispered, respecting the deep shadows and the deeper time. “How’re we supposed to dig this thing outta here?”

“We’re not,” she told them. She scooted sideways between the wall of concrete and the tower of machinery. “This thing is meant to dig its own way out.”

“You’re assuming we can get it running,” Dawson said.

Workers in the generator room crowded the hole and blocked the light spilling in. Juliette steered her flashlight around the narrow gap that stood between the outer silo wall and the tall machine, looking for some way around. She worked to one side, into the darkness, and scrambled up the gently sloping floor.

“We’ll get it running,” she assured Dawson. “We just gotta figure out how it’s supposed to work.”

“Careful,” Raph warned as a rock kicked loose by her boots tumbled toward him. She was already higher up than their heads. The room, she saw, didn’t have a corner or a far wall. It just curled up and all the way around.

“It’s a big circle,” she called out, her voice echoing between rock and metal. “I don’t think this is the business end.”

“There’s a door over here,” Dawson announced.

Juliette slid down the slope to join him and Raph. Another flashlight clicked on from the gawkers in the generator room. Its beam joined hers in illuminating a door with pins for hinges. Dawson wrestled with a handle on the back of the machine. He grunted with effort, and then metal cried out as it reluctantly gave way to muscle.

The machine yawned wide once they were through the door. Nothing prepared Juliette for this. Thinking back to the schematics she’d seen in Solo’s underground hovel, she now realized that the diggers had been drawn to scale. The little worms jutting off the low floors of Mechanical were a level high and twice that in length. Massive cylinders of steel, this one sat snug in a circular cave, almost as if it had buried itself. Juliette told her people to be careful as they made their way through the interior. A dozen workers joined her, their voices mingling and echoing in the maze-like guts of the machine, taboo dispelled by curiosity and wonder, the digging forgotten for now.

“This here’s for moving the tailings,” someone said. Beams of light played on metal chutes of interlocking plates. There were wheels and gears beneath the plates and more plates on the other side that overlapped like the scales on a snake. Juliette saw immediately how the entire chute moved, the plates hinging at the end and wrapping around to the beginning again. The rock and debris could ride on the top as it was pushed along. Low walls of inch-thick plate were meant to keep the rock from tumbling off. The rock chewed up by the digger would pass through here and out the back, where men would have to wrestle it with barrows.

“It’s rusted all to hell,” someone muttered.

“Not as bad as it should be,” Juliette said. The machine had been there for hundreds of years, at least. She expected it to be a ball of rust and nothing more, but the steel was shiny in places. “I think the room was airtight,” she wondered aloud, remembering a breeze on her neck and the sucking of dust as she pierced through the wall for the first time.

“This is all hydraulic,” Bobby said. There was disappointment in his voice, as though he were learning that the gods cleaned their asses with water too. Juliette was more hopeful. She saw something that could be fixed, so long as the power source was intact. They could get this running. It was made to be simple, as if the gods knew that whoever discovered it would be less sophisticated, less capable. There were treads just like on the excavator but running the length of the mighty machine, axles caked in grease. More treads on the sides and ceiling that must push against the earth as well. What she didn’t understand was how the digging commenced. Past the moving chutes and all the implements for pushing crushed rock and tailings out the back of the machine, they came to a wall of steel that slid up past the girders and walkways into the darkness above.

“That don’t make a lick of sense,” Raph said, reaching the far wall. “Look at these wheels. Which way does this thing run?”

“Those aren’t wheels,” Juliette said. She pointed with her light. “This whole front piece spins. Here’s the pivot.” She pointed to a central axle as big around as two men. “And those round discs there must protrude through to the other side and do the cutting.”

Bobby blew out a disbelieving breath. “Through solid stone?”

Juliette tried to turn one of the discs. It barely moved. A barrel of grease would be needed.

“I think she’s right,” Raph said. He had the lid raised on a box the size of a double bunk and aimed his flashlight inside. “This here’s a gearbox. Looks like a transmission.”

Juliette joined him. Helical gears the size of a man’s waist lay embedded in dried grease. The gears matched up with teeth that would spin the wall. The transmission box was as large and stout as that of the main generator. Larger.

“Bad news,” Bobby said. “Check where that shaft leads.”

Three beams of light converged and followed the driveshaft back to where it ended in empty space. The interior cavern of that hulking machine, all that emptiness in which they stood, was a void where the heart of the beast should lie.
