The crowbar trembled under Fellis’s weight, the tough iron shaft groaning as the boy’s heavy boots skated half an inch in the slick trench clay.
“Get a line on it!” Kezra called out, dropping her shovel and stepping forward to brace his shoulder. “Don’t let the pry-claw jump the slot!”
Yseld was already moving with the unrushed speed of an experienced mountain scout. From Fellis’s cargo bundle on the edge of the limestone platform, the guide grabbed a four-pace length of braided rawhide strap fitted with an iron cinch-ring. She dropped into the narrow trench beside Kezra. She whipped the strap twice around the upper end of the crowbar. She passed the running end through the iron ring to form a non-slip prusik loop that gripped the metal like a vise.
“On three!” Yseld ordered, planting her heels firmly against the base of the platform’s cut stone retaining wall. “Dain, keep the pry-claw square under the pin head. Don’t let it twist sideways or you’ll shear the lip. Venn, take the rear strap with me. Keep your knees bent and lift with your thighs, not your back! One... Two... Three—heave!”
Kezra leaned back with all her strength, throwing her hips and the full weight of her torso into the haul alongside Yseld.
For a heartbeat, the world seemed to narrow to the sharp stench of burnt lamp oil, the bitter bite of rawhide cutting through her woollen mittens into her palms. The dead, unmoving pushback of thirty years of rusted iron cemented in lime mortar.
Then came a sound like a pistol shot. A sharp, explosive crack that echoed out across the quiet hillside and sent three birds fluttering out of the roadside hawthorns.
The cotter pin popped.
The narrowed wrought-iron wedge jumped an inch straight out of its slotted shank. It spat a shower of dry, orange rust flakes, fractured stone grit, and hardened mortar onto Fellis’s knees. Fellis gasped, threw his shoulder hard against the bar. Then he pried the wedge upward with a long, painful scrape until the iron clattered free into the trench dirt.
With the cotter pin removed, the tension died instantly in the iron. Fellis took his small hand hammer and a short bronze drift pin from his pouch. He tapped the end of the tie-rod backward through the eye-bolt. With a dry, grating screech of rusted metal sliding across stone, the wrought-iron bar slid clear of the platform’s mounting block, withdrawing fully into the foundation wall of the ruined tally shed.
“She’s free,” Fellis panted. He sat back in the mud and wiping a thick streak of red rust across his forehead with his sleeve. “She’s fully clear of the platform. There’s two inches of daylight between the eye and the rod.”
Kezra didn’t waste a second celebrating. She grabbed her shovel and began pitching the excavated clay and limestone aggregate back into the trench. Meanwhile, Fellis tamped the fill down with the heavy iron butt of the crowbar, packing it tight in four-inch lifts so the ground wouldn’t settle under autumn rains. Together, they laid the cut sods back over the seam, stamping them flat with their boots until the grass met the surrounding turf within two fingers’ breadth.
Kezra knelt on the restored grass and placed her fingertips on the western corner coping stone of the weighing platform.
She tapped her sounding rod against the stonework.
Tock.
The high, singing, metal ring was fully gone. In its place came the deep, solid, gravelly deep ring of dressed stone resting firmly on its own bedded limestone footings. There was no shaking leaping across the grass to the ruined shed. No red refusal line flared in her mind or across the thick parchment of her notebook. The platform sat wholly independent inside its sixteen-pace boundary.
“Surface separation is clean,” Kezra said. She rose to her feet and brushing the dry earth from her knees. “Now we have to go down.”
Fellis looked up, his brow furrowing into lines of dismay. “Down? Kezra, we just spent two hours digging that trench and packing the dirt back in! You can’t want another hole!”
“That was twelve inches deep,” Kezra said. She pointed down with her rod toward the center of the earth. “Plot scale extends eight paces deep—nearly twenty-five feet into the bedrock beneath our boots. Rule Three. Physical survey needs check of every attached structure and physical descent to the deepest accessible point within the volume before grid soundings can be checked. I can’t just tap the grass and assume the rock under the platform is solid. If there’s an old underground kiln gallery, an unmapped water tank. Or a collapsed drainage vault under this stone, the whole prism will fail when I try to certify it. Or worse, if I swap it, the platform will arrive with a hollow cavity that collapses under the first wagon.”
Yseld shaded her eyes, looking thirty paces down the hillside to where a low, overgrown limestone escarpment broke through the turf.
“The lime pit,” Yseld said, pointing with her staff. “Every weighing station built on a major lime route had an extraction pit or a settling cellar beneath it where the wagon drivers shoveled out spilled burning lime powder and stored dry sacks out of the weather. The entrance should be right at the foot of that rock bench.”
Leaving Paxa to guard the mule and watch the surface stakes, Kezra, Fellis, and Yseld walked down the slope to the base of the escarpment.
Behind a dense curtain of dead brambles and wild gooseberry scrub, they found the entrance. A low, arched portal four feet high and three feet wide, framed with rough-hewn limestone arch stones. The air that breathed out of the opening was cold and still. It smelled of damp rock, ancient woodsmoke, and the sharp, bitter-salt tang of wet lime plaster.
Yseld stepped to the mouth of the arch, thrusting her hooked staff inside to test the stone roof. She rapped the ceiling flags sharply, listening to the return with her head tilted.
“Roof is sound bedded limestone,” Yseld reported, stepping back to let Kezra see. “No fresh rock-falls. The air is moving—there’s an old air-flow chimney pipe somewhere in the rear wall. But the ceiling is barely four feet high. You’ll be crawling on your elbows, Venn.”
Fellis rigged an anchor line around a stout hawthorn trunk outside the portal, tying a heavy hemp safety tether around Kezra’s waist with an adjustable bowline knot. From his pack, he produced a small, brass-shuttered horn lantern, lighting the animal fat wick from his tinderbox and handing it to her alongside her three-arm-length sounding rod.
“If you pull twice on the line, I haul you out,” Fellis said, his voice unusually serious as he checked the knot. “If you pull three times, Yseld comes in with the crowbar and the short axe. Don’t go poking into blind crevices.”
“I’m going to measure stone, Fellis, not hunt badgers,” Kezra said with a faint smile, though her stomach felt tight and hollow as she took the lantern.
She dropped to her hands and knees and crawled into the dark.
The tunnel sloped downward at a sharp ten-degree grade, its floor covered in a thick, powdery carpet of dry, white lime dust that puffed up around her knees like fine flour. She kept the lantern held low, its pale yellow beam lighting up low walls of dry-stacked limestone rubble supporting a ceiling of massive, level limestone slabs.
Ten paces in, the passage opened into a box-shaped underground chamber roughly eight paces wide and twelve paces long.
Kezra brought up her sighting tube and compass, orienting herself to the surface map points above. By her pace count and the angle of the descent, she was standing directly beneath the center of the weighing platform—exactly eight paces below the surface datum of the road.
She raised the lantern, examining the ceiling.
Above her head, the underside of the weighing platform was supported by three massive, hand-hewn oak stone wall-brackets resting on bedrock pillars. The timbers were dry and grey with age, but entirely sound, free of dry rot or fungal decay. More importantly, she checked that no underground drainage channels, buried iron pipes, or forgotten quarry adits extended past the upright outer edge planes of the sixteen-pace square.
She knelt in the center of the chamber, setting the lantern on a flat stone.
She took her sounding rod, unhitched the iron line weight from her belt. Then she measured the exact upright distance from the chamber floor to the underside of the roadway flags: six point four meters. Exactly eight survey paces.
Then she brought the iron shoe of her rod down against the exposed bedrock floor of the pit.
Tock.
The sound traveled through the rock and into her bones. A pure, heavy, echoing tone that confirmed the geology. Solid, horizontally bedded upland limestone resting over compact, dry chalk marl. No underground caverns. No water-filled sinkholes. No load-bearing fractures crossing the boundary planes.
She took a piece of red chalk from her pocket. Then she drew a spotless, four-inch cross on the bedrock at the deepest point of the pit, marking the exact underground datum of the parcel.
“Datum checked,” she whispered into the cool dark. “Bedded limestone over marl. Eight paces deep.”
She crawled backward out of the low tunnel, emerging into the blinding afternoon sunlight to find Fellis and Yseld waiting at the entrance.
“Well?” Fellis asked, hauling in the slack on her tether.
“Eight paces deep, solid limestone floor, zero voids,” Kezra said, squinting against the glare as she unbuckled the safety line. “The volume is fully legal. Let’s drive the outside anchors.”
They climbed back up to the platform.
Under Rule Four, a legal parcel needed three cut-stone anchor marks carved by the map maker’s own hand into stable, living rock just outside the outer edge. Outside anchors remained at their geographic map points when a parcel exchanged. Because of that, their placement was critical. They had to be stable, permanent, and accessible from outside the boundary.
Kezra knelt at the northwest corner of the sixteen-pace square, two feet outside the boundary line. There, a low shelf of living bedrock protruded through the turf.
With her iron stone-chisel and a small mallet, she began to carve her personal anchor mark. A four-inch split triangle, crossed by two level leveling bars. The cold iron bit into the limestone with crisp, rhythmic strokes—clink, clink, clink—sending pale rock dust flying across the grass.
She carved the second anchor outside the southwest corner, into a massive, frost-heaved boulder embedded deep in the road verge.
Finally, she walked to the northeast corner. There, a flat limestone ledge flanked the roadside ditch.
Kezra drove the third cut-stone anchor mark outside the northeastern corner of the platform. Then, the chisel biting clean and deep into the bedrock, the bonded notebook’s page warmed against her palm.
