Gould Plug and Wedge Mill (Camden, Knox County, Maine): Origins of Industrial Production on the Megunticook River (c. 1855–late 19th century)

The Gould Plug and Wedge Mill represents one of the earliest identifiable industrial enterprises on the Washington Street corridor of the Megunticook River in Camden, Maine. Although later overshadowed by woolen manufacturing and tanning industries, the Gould operation is historically significant as the foundational industrial use of what would later become the Tannery Park site. Established around the mid-nineteenth century, the mill reflects Camden’s early transition from a mixed agrarian–maritime economy into a water-powered industrial landscape.

The site that hosted the Gould Plug and Wedge Mill was part of a broader system of “mill privileges” along the Megunticook River—designated points where water flow could be harnessed for mechanical power. By the 1850s, Camden had begun to diversify beyond shipbuilding and agriculture, developing a range of small manufacturing enterprises including sawmills, gristmills, and specialized production facilities. Within this context, the Gould operation emerged as a niche industrial enterprise focused on producing wooden components essential to maritime construction and trade.¹

Establishment and Industrial Function

The Gould Plug and Wedge Mill is associated with Amasa Gould, who operated a plug and wedge manufacturing facility at the fourth mill privilege along the Megunticook River, near what is now Washington Street and Megunticook Street. The mill’s location was strategically chosen for its waterpower potential and proximity to Camden’s shipbuilding economy.²

The primary products manufactured at the Gould mill were wooden plugs and wedges, components widely used in nineteenth-century maritime and construction industries. Plugs were employed in shipbuilding to seal bolt holes and fasten structural timbers, while wedges were used for securing joints and adjusting wooden frames. These were not decorative items but essential industrial inputs integrated into ship construction and repair systems.

Contemporary accounts and later historical reconstructions suggest that Gould’s products were distributed beyond Camden’s immediate shipyards, reaching markets along the Maine coast and potentially extending to larger port cities. This reflects the integration of even small-scale manufacturers into broader maritime supply chains during the mid-nineteenth century.³

Technology and Production Context

The Gould Plug and Wedge Mill operated during a period of increasing mechanization in small-scale manufacturing. By the mid-1850s, specialized machinery had begun to automate plug and wedge production, improving efficiency and standardizing output. Regional industrial histories note the role of machinists such as David Knowlton, who contributed to the development and maintenance of mill machinery in Camden’s industrial corridor.⁴

Despite these technological developments, the Gould mill remained relatively small in scale. It reflected a transitional industrial form characteristic of rural Maine: partially mechanized, water-powered, and embedded in local trade networks rather than corporate manufacturing systems.

Labor and Industrial Environment

The Gould operation likely employed a small workforce consisting of skilled machinists, carpenters, and general laborers. While no surviving payroll records exist, labor patterns in mid-nineteenth-century Camden suggest a fluid workforce that moved between seasonal agriculture, shipbuilding, and mill labor depending on economic demand.

The mill operated within a concentrated industrial landscape along the Megunticook River, which included sawmills, gristmills, and later textile facilities. This clustering of industries reflects the importance of waterpower as a central organizing feature of Camden’s early industrial geography.

Transition and Absorption into Larger Industrial Systems

The Gould Plug and Wedge Mill did not remain a long-term independent enterprise. By the late nineteenth century, Camden’s industrial economy was undergoing consolidation. Larger textile firms, particularly woolen manufacturers, began to absorb or replace smaller specialized operations along the river corridor.

By the 1880s and 1890s, the site formerly associated with Gould had been incorporated into the expanding industrial footprint of the Camden Woolen Company, which established large-scale textile production in the broader Washington Street corridor.⁵ This transition reflects a regional pattern in which small water-powered mills were either repurposed or replaced by vertically integrated industrial enterprises capable of higher output and workforce expansion.

The Gould mill itself disappears from the industrial record as an independent entity during this period, but its site remained central to subsequent industrial development.

Historical Significance

Although short-lived as a standalone enterprise, the Gould Plug and Wedge Mill holds historical importance for several reasons:

It represents one of the earliest industrial uses of the Washington Street mill corridor.
It reflects Camden’s integration into maritime supply chains through specialized manufacturing.
It illustrates the pre-corporate phase of New England industrialization, when small water-powered mills dominated production.
It established the physical and economic foundation for later industrial occupants, including woolen mills and tanneries.

In this sense, the Gould Plug and Wedge Mill should be understood not as an isolated enterprise, but as the initial layer in a continuous industrial sequence that extended through Camden Woolen Company, Camden Tanning Company, Apollo Tanning Ltd., and ultimately into the modern Tannery Park landscape.

Tannery Park, Camden, Maine: A Continuous Industrial History of the Megunticook River Corridor (c. 1813–Present)

Introduction

Tannery Park on Washington Street in Camden, Knox County, Maine occupies one of the most historically stratified industrial landscapes along the Megunticook River. What is now a public riverfront space was, for nearly two centuries, a continuously evolving industrial corridor shaped by waterpower, shifting manufacturing technologies, and changing economic regimes. The site’s history cannot be understood through a single company or industry; instead, it is best interpreted as a layered sequence of enterprises that reused the same mill privileges for different forms of production.

From early nineteenth-century tannery activity to specialized plug-and-wedge manufacturing, from woolen textiles to industrial tanning, and finally to municipal ownership and farmers’ market use, the site reflects the broader transformation of rural New England from decentralized craft production to industrial capitalism and ultimately to post-industrial public space.

I. Early Mill Privileges and Proto-Industrial Use (c. 1813–1850s)

The earliest documented industrial activity in the Washington Street corridor dates to the early nineteenth century, when mill privileges along the Megunticook River were developed for small-scale industrial use. In this period, the site that would become Tannery Park was part of a dispersed system of water-powered enterprises including sawmills, gristmills, and early manufacturing shops.

Among the earliest identifiable uses was tannery activity associated with small-scale leather production. These early operations were typical of New England river towns, relying on bark-derived tannins and river access for processing hides. While documentation from this earliest phase is fragmentary, the industrial logic is clear: waterpower, proximity to livestock supply chains, and access to Camden’s growing maritime economy.¹

This early phase established the site as a working industrial landscape, rather than undeveloped land, embedding it in the economic geography of Camden.

II. Gould Plug and Wedge Mill: Specialized Early Manufacturing (c. 1850s–1860s)

By the mid-nineteenth century, the site became associated with the Gould Plug and Wedge Mill, operated by Amasa Gould. This enterprise represents one of the earliest identifiable industrial firms on the Washington Street corridor.

The mill specialized in the production of wooden plugs and wedges, essential components in shipbuilding and wooden construction. Plugs were used to seal fasteners in ship hulls, while wedges were used in structural fitting and timber adjustment. These products connected Camden’s industrial output directly to Maine’s maritime economy.

Production was water-powered and small in scale, characteristic of early industrial enterprises before the rise of large textile corporations. The Gould mill represents a transitional phase between artisanal production and industrial manufacturing, where mechanization began to supplement traditional woodworking labor.²

Although short-lived as an independent enterprise, the Gould mill established the site’s long-term industrial trajectory by anchoring it in mechanized production and river-powered industry.

III. Camden Woolen Company and Textile Industrialization (c. 1870s–early 1900s)

By the late nineteenth century, the Washington Street corridor was absorbed into the expanding textile economy of Camden through the Camden Woolen Company. Sanborn Fire Insurance maps from this period document substantial mill structures, indicating a fully developed industrial facility replacing earlier small-scale enterprises.³

The woolen mill marked a fundamental shift in the site’s function. Where earlier industries were small and specialized, the woolen mill was industrial in scale, organized around wage labor and continuous production. The facility processed raw wool into woven textiles, including coarse cloth and utilitarian fabrics used in regional markets.

The Camden Woolen Company also reshaped the surrounding landscape. Worker housing, transportation routes, and supporting infrastructure developed in proximity to the mill, embedding industrial labor into the daily life of the Washington Street corridor.

This period represents the site’s integration into New England’s broader textile system, linking Camden to regional and national markets.

IV. Camden Tanning Company: Chemical Industry and Environmental Transformation (1953–1990s)

In the mid-twentieth century, as textile manufacturing declined in New England, the site underwent another major transformation with the establishment of the Camden Tanning Company in 1953. This marked a shift from textile production to leather processing, reflecting broader industrial adaptation strategies in declining mill towns.

The tannery processed animal hides using chemical tanning methods, including the use of tanning agents and industrial wastewater systems. This phase introduced a more environmentally intensive form of production than earlier industries, significantly affecting soil and river conditions along the Megunticook River.⁴

The Camden Tanning Company represents the site’s longest sustained industrial phase in the modern era, continuing operations for several decades and maintaining the property as an active industrial facility even as other mills in the region closed.

V. Apollo Tanning Ltd.: Final Industrial Operator (1997–2000)

The final industrial occupant of the site was Apollo Tanning Ltd., which began operations in 1997 under a lease arrangement. By this time, the facility was an aging industrial complex with legacy environmental issues from previous tanning operations.

Apollo continued limited leather processing, focusing on sheepskin tanning and finishing. The operation was small in scale, employing only a few workers and producing specialized leather products rather than large-scale industrial output.⁵

In 1999, Apollo ceased operations amid financial and operational difficulties. The company filed for bankruptcy in 2000, marking the end of continuous industrial activity on the site after nearly two centuries.

Apollo’s closure represents the definitive end of Camden’s Washington Street industrial corridor as a production site.

VI. Municipal Acquisition and Environmental Transition (2000s)

Following the closure of Apollo Tanning, the property entered municipal ownership through tax foreclosure. The Town of Camden assumed control of the site in the early 2000s, initiating environmental assessment and remediation efforts.

The site was identified as a brownfield due to long-term industrial contamination associated with tanning and earlier manufacturing activities. Cleanup efforts included soil stabilization, removal of hazardous materials, and environmental monitoring.⁶

This transition marked a fundamental shift in land use: from industrial production to public environmental management.

VII. Tannery Park and Post-Industrial Civic Use (1974–Present)

Even before full municipal redevelopment, the site and surrounding corridor began to be used for civic and community purposes. Most significantly, the Camden Farmers’ Market, established in 1974, has periodically operated in the Washington Street area, including the Tannery Park site.⁷

The farmers’ market represents a symbolic and functional transformation of the landscape. Where industrial production once dominated, seasonal agricultural commerce now defines the space. Vendors selling produce, baked goods, and artisan products occupy the former industrial ground, reactivating the site as an economic and social hub.

In its current form, Tannery Park functions as:

• a public green space

• a seasonal farmers’ market venue

• a riverfront access area

• a planning site for ongoing redevelopment discussions

The industrial past remains visible in the landscape, but the site now operates primarily as civic infrastructure rather than manufacturing space.

Conclusion

The history of Tannery Park is not the history of a single company or industry, but a continuous sequence of adaptation along the Megunticook River. From early tannery activity to Gould’s plug and wedge manufacturing, from woolen production to industrial tanning, and finally to Apollo Tanning’s closure and municipal redevelopment, the site demonstrates how industrial landscapes evolve rather than disappear.

Today, Tannery Park stands as a layered historical environment where each phase of use remains embedded in the physical and cultural fabric of Camden. Its transformation into a public space and farmers’ market reflects not the erasure of industrial history, but its repurposing into a new civic form.
