Camden's Knox Woolen Mill made felts for Maine's growing paper industry and other industries. It was located to take advantage of the waterpower available in Camden. This photo shows some of the employees of the company. In the 1890s the company expanded greatly and built the building now visible in Camden.
Castine had ropewalks in the early 1800s, one burning in 1828 and its replacement burning in 1830. J.W. Dresser had a ropewalk business in the second half of the nineteenth century, here shown on a winter or early spring day. By the 1870s, though, it was made up of a head house on Pleasant Street and a long, low dilapidated building with three machines making 80 dozen lines per day. Toward the end of the company's operation, it specialized in fishing lines, including long trawl lines. The Dresser Rope Walk was purchased in 1900 and became known as the Line and Twine Factory.
The Brewer waterfront from the Bangor shore or from a boat in the Penobscot River. The large building to the right is an ice house. Next to it lies the Barbour shipyard with a steamboat, probably the Sedgwick under construction.
Lilly Pond in Rockport was an important source of ice. After scraping snow from the ice and letting the ice get to be about 18 inches thick, cutters sawed the ice into blocks. Another large source of ice was Lake Chickawaukee in Rockland.
Preliminary Geological Map of Maine, showing soil and rock types. Note especially the avacado green line that extends from Thomaston almost to Camden; that is limestone. Also, the pink with red flecks on the map shows where there is granite. Note the granite from St. George, across Penobscot Bay to the southern part of Vinalhaven, on to the Stonington area. Also, there are significant granite resources in northern Penobscot Bay, where there were quarries in the Mt. Waldo area of Frankfort.
Dougherty lime quarry in Rockland was one of a number of quarries in the Rockland / Camden area. The steam engine in the bottom of the quarry could power air compressors to drive air drills or cranes to hoist out the cut stone.
This map, based on a map from the Maine GIS Library, shows major towns and islands in Penobscot Bay. Yellow on the west side of the Bay shows the approximate location of lime deposits. Pinkish tan shows granite quarrying areas, both along the southern part of the Bay and also in Frankfort. Reddish-brown depicts the location of some of Penobscot Bay's brick industry. More brickmaking occurred upriver in Orrington and Brewer, on the east side of Penobscot Bay.
