The Reckoning in the Workyard

In March 1812, months before the Board’s final audit and judgment, an itemized account arrived at the Northern Lighthouse Board’s Edinburgh offices, a nine-page memorandum from master mason Peter Logan. The document, folded and pinned with a corroding brass clasp, was copied fair by a clerk and countersigned by Logan in a heavy, deliberate hand. Its pages carried the smell of the Arbroath workyard—stone dust, train oil, the faint iodine of seaweed from the Bell Rock—and presented a catalogue of the granite courses supplied for the lighthouse.

Each page was ruled in columns. The first named the course—Base, First, Second, running up to the thirty-sixth and final course that had been set in the summer of 1810.

The second column gave the number of stones: 1, 336 blocks in all, though the tally was not continuous, for the Beacon House course and the Light Room course each stood as single entries of exceptional weight and complexity. The third column listed the cubic feet of finished stone, a figure that diminished as the tower narrowed toward its lantern. The fourth gave the price per cubic foot, graduated according to the difficulty of the work.

The base stones, rough-hewn and massive, commanded less per foot than the interlocking joggles of the upper courses, where precision of a few thousandths of an inch had been necessary to achieve the self-locking stability that would hold the tower against the sea.

The final column ran the multiplication: course by course, stone by stone, the accumulated cost of turning raw granite from the Rubislaw quarry into the shaped and numbered components of a lighthouse that now stood eleven miles offshore, its lamp burning through the winter nights.

The total was £23, 847 12s. 6d. It represented four years of Logan’s life, the transformation of his yard from a modest masonry operation into a precision manufactory, and the labor of sixty men through seasons when the work had to proceed regardless of weather or the state of the harbor. The Commissioners set the bill on the green baize of their committee table and began to read it not as a narrative of construction but as a document to be tested.

What Stevenson had assembled through years of journals and careful distinction was now his to deploy. The resident engineer had spent the years of building accumulating the materials for authority: the correspondence filed with the Board, the records that separated his daily decisions from the periodic interventions of John Rennie, the consulting engineer who had visited the site twice and approved the designs from Edinburgh. The lighthouse stood. The light burned. The ships passed safely.

But the formal conclusion of the Bell Rock project was not marked by the lighting of the lamp on that February evening in 1811. It came in this protracted, granular administrative and financial settlement conducted far from the rock itself, a process that revealed the true cost and complexity of the enterprise in human and material terms. The Commissioners had commissioned an achievement. They were now required to pay for it, and to verify that they had received what they had paid for.

The audit began with cross-reference. The Board’s clerk, a methodical man named Farquhar who had served through three changes of administration, laid Logan’s bill beside the shipping registers from the workyard. Each course of stone had been transported to the Bell Rock in the Smeaton or the Pharos, and each shipment had been logged with a date and a tally of blocks. Farquhar worked backward from the final course, comparing Logan’s cubic-foot measurements against the dimensions recorded when the stones had been loaded. Discrepancies appeared immediately. The twenty-fourth course, laid in August 1809, showed a shortfall of twelve cubic feet in Logan’s account against the shipping register. The discrepancy was small—less than one percent of the course total—but it established a principle. The Board would verify every claim.

Logan was summoned to Edinburgh. He arrived with his own clerk and a folio of supporting papers: quarry receipts, wages books, the specifications that Stevenson had approved for each course. The interview was conducted not by the full Board but by a subcommittee of three Commissioners, with Stevenson present as the engineer who had supervised the work. The questioning was precise and unhurried. How had the twenty-fourth course been measured? Had the stones been dressed to final dimension before shipment, or had final cutting occurred on the rock? What allowance had been made for the joggles and trenails that locked each block to its neighbors? Logan’s answers were careful, for he understood that his reputation and his payment depended upon them.

The stones had been roughed at Arbroath, finished to template on the rock during the brief working tides. The measurements in his bill represented the finished work as incorporated into the tower, not the rough blocks as shipped. The cubic-foot discrepancy in the twenty-fourth course could be explained by the final dressing: stone removed to achieve the precise fit that Stevenson had demanded.

Stevenson confirmed this. His own journals, which he had begun preparing for publication, recorded the daily progress of dressing and setting. The twenty-fourth course had presented particular difficulty. A flaw in one of the corner stones, discovered only when the block had been set and tested, had required its removal and replacement. The rejected stone, logged in the shipping register by its rough dimensions, had been replaced by another of different proportion. The finished work matched the specification; the raw material consumed had exceeded it. The Commissioners accepted the explanation, but they noted it. The bill would be paid, but paid with attention to the difference between what had been ordered, what had been supplied, and what had actually been required by the circumstances of the work.

The administrative reckoning that the Bell Rock demanded took this form. The tower appeared permanent, a solid fact of geometry and granite rising from a reef that had destroyed ships for centuries. Its permanence was an illusion sustained by paperwork. Each block depended for its place in the structure upon the records that had tracked it from quarry to workyard to ship to rock, and upon the financial instruments that had mobilized the labor to shape and set it. The Commissioners, in verifying Logan’s bill, were performing the same function that the interlocking joggles performed in the tower itself: they were locking the components into a stable whole, preventing the settlement and displacement that would otherwise follow from the sheer weight of the enterprise.

The audit proceeded course by course, stone by stone. The Beacon House course, that massive foundation of twenty-four blocks set in the summer of 1808 to carry the temporary wooden shelter, was examined with particular care. Rennie had specified the course in his original design; Stevenson modified it after the 1807 season demonstrated the inadequacy of the initial foundation scheme. Logan’s bill claimed £1, 847 for this course alone, a figure that included the cutting of the stones, their experimental fitting in the yard, the cutting of the first temporary joggles, and the subsequent modification of those joggles when the design changed.

The Commissioners asked to see the correspondence. Stevenson produced it: his letters to Rennie of October and November 1807, describing the conditions encountered on the rock, Rennie’s cautious approval of the Beacon House scheme, the subsequent exchange when the wooden structure had proven necessary. The paper trail was complete. The Beacon House course had been expensive because it had been experimental, a prototype for the permanent tower that had also served as the foundation for the temporary accommodation. The Board had authorized the experiment. They paid for its consequences.

The settlement of Logan’s account took six weeks. When it was concluded, the master mason received £23, 400, a reduction of £447 from his original claim. The difference represented not dispute but verification: the Commissioners had accepted his explanations for the discrepancies but had applied a standard deduction for minor variations that could not be fully documented. Logan accepted the settlement without protest. He had been paid for the most demanding masonry work ever undertaken in Scotland, and he had been paid by an institution that would remember his competence. The Bell Rock lighthouse was the world’s oldest surviving sea-washed lighthouse, and his stones were its substance.

But the reckoning did not end with the master mason. The Board’s attention turned to the workforce that had been dispersed when the work concluded. The Arbroath yard had employed, at its maximum, sixty men: masons, smiths, laborers, the carpenters who built the temporary joggles and the tackle that moved the stones. Most had been hired by the season, their wages calculated by the day or the piece. A few had been retained through the winter to maintain the yard and prepare for the next season’s work. The final accounts required their discharge, the calculation of any sums due, and the formal termination of their connection to the project.

James Dove appeared in the records as a representative case. He had been hired in April 1807 as a common laborer, promoted to foreman of the stone-dressers in 1808, and retained through the completion of the work in 1810. His wage had risen from twelve shillings to eighteen shillings per week, a substantial increase that reflected both his competence and the scarcity of skilled men willing to endure the conditions of the rock. The Board’s clerk calculated his final account: wages due for the last quarter of 1810, a bonus of £5 voted by Stevenson for his service during the difficult 1809 season, the balance of a subscription fund that the workmen had maintained for the relief of injured colleagues. Dove was owed £14 7s. 6d. He received it in cash, counted out by Farquhar in the Board’s offices, and signed the receipt with a mark rather than a signature, for he could not write his name.

The transaction was recorded in three places: the wages book that Logan retained for his own accounts, the Board’s payment register, and the final ledger that would be submitted to the Treasury as evidence of the proper expenditure of public money. Dove’s mark, witnessed by a clerk who wrote his name beneath it, became part of the permanent record of the Bell Rock. His labor, his promotion, his bonus, his illiteracy—all were fixed in the documentation that proved the project had been conducted with proper regard for economy and accountability.

Francis Watt appeared in a different category. The carpenter had been employed not by Logan but by Stevenson directly, for the design and construction of the lighthouse’s lighting apparatus. His contribution had been technical rather than manual: the arrangement of mirrors and lamps, the mechanism of the revolving frame that produced the characteristic flash, the precise geometry of reflection that would project a beam visible at eleven miles. The Board had authorized £800 for this apparatus, a figure that included materials and Watt’s fee. The final settlement required an inventory of what had been supplied, for the apparatus remained the Board’s property and would require maintenance and eventual replacement.

Watt submitted his account in April 1812. It listed the parabolic mirrors, the Argand lamps, the clockwork mechanism, the copper and brass fittings, each with a price derived from the London suppliers who had manufactured them to his specification. The total was £743 12s., leaving a margin against the authorized sum that Stevenson had held in reserve for contingencies. The Commissioners examined the inventory with attention, for they understood that this apparatus, more than the granite tower that contained it, represented the functional purpose of the expenditure. The lighthouse was a machine for producing light, and Watt’s account described the components of that machine.

The verification of Watt’s charges was delegated to Stevenson, as the engineer who had supervised the installation. He confirmed that the mirrors were of the specified diameter and focal length, that the clockwork maintained the proper period of revolution, that the whole apparatus had operated without failure since the lighting of the lamp. The Board accepted his certification and authorized payment. Watt received his sum and returned to his other employments, his connection to the Bell Rock reduced to a line in the ledger and the continuing function of his design.

These individual settlements—the master mason’s bill, the foreman’s wages, the carpenter’s fee—were components of a larger accounting that the Board conducted in the years following the lighthouse’s completion. The total expenditure had to be established, reconciled with the parliamentary grants that had authorized the work, and submitted to the Treasury as the formal conclusion of the project. The financial reckoning transformed a heroic construction into a closed administrative episode.

The figures accumulated. The parliamentary grant of 1806 had authorized £30, 000 for the lighthouse, a sum that the Board had understood to be preliminary, subject to revision as the work revealed its true cost. Subsequent grants in 1808, 1809, and 1810 had raised the authorized total to £61, 331. The actual expenditure, calculated through 1812, was £59, 821 14s. 10d. The difference of £1, 509 represented the margin by which the Board’s estimates had exceeded necessity, or alternatively the efficiency with which Stevenson and his contractors had conducted the work. The Commissioners chose to interpret it as evidence of careful management. They reported to the Treasury that the Bell Rock lighthouse had been completed within the sums authorized by Parliament, a statement that was technically true and politically valuable.

But the true cost was not captured in these parliamentary figures. The Board’s accounts recorded only the money expended: the wages, materials, shipping, the purchase of the Smeaton and the hire of the Pharos. They did not record the cost in human bodies, though these had been itemized in other documents. John Bonnyman’s finger, amputated in September 1808 after an accident with the beam crane, had cost the subscription fund £3 in relief and had earned Bonnyman his subsequent appointment as one of the first lighthouse keepers.

The three men who had been injured in the 1807 season, the two in 1808, the single fatality in 1809 when a laborer named Henderson had been swept from the rock by an unexpected wave—these were noted in Stevenson’s journals and in the minutes of the subscription fund, but they did not appear in the final accounts submitted to the Treasury. The lighthouse had been built within budget. Its builders had paid other prices.

The disposition of the physical assets completed the reckoning. The Smeaton, the sixty-ton sloop that had served as floating workshop and accommodation through four seasons, was offered for sale in 1811. She was a specialized vessel, built to Stevenson’s design with a flat bottom for grounding on the rock and a hold adapted for the transport of stone. The Board had paid £750 for her construction in 1807. She was sold in 1812 for £320 to a Leith shipowner who intended to convert her to a coastal trader. The depreciation—£430 in four years of hard service—was entered in the accounts as a loss against the project. The Pharos lightship, which had been hired rather than purchased, was returned to her owners in 1811, her service at the Bell Rock concluded.

These transactions removed the last physical traces of the construction from the Board’s responsibility. The Smeaton would sail for another decade under new ownership, her flat bottom and reinforced scantlings the only evidence of her original purpose. The workyard at Arbroath was cleared, the sheds dismantled, the templates and joggles that had guided the cutting of 1, 336 stones burned as firewood or left to rot. The granite tower alone remained, maintained now by a staff of keepers who kept the light burning and recorded in their own logbooks the weather, the shipping, the occasional failures of apparatus that required replacement.

The settled material facts—the counted stones, paid wages, sold ships—now stood as fixed, incontrovertible data, ready to be weaponized in the coming public battle over credit. Stevenson had his documentation. Rennie had his. The Board had its closed accounts. The reef had its tower. What remained was the question of whose name would attach to what had been made, and the documents that each man had gathered through these years of reckoning would determine the answer.
