Joe:
I hope you understand my reticence to display the maps until I better understood what you are doing out there. I never want to aid pot-holers in their dastardly deeds of destroying undisturbed archaeological sites.
You may have already examined some of these maps, but I will post them for others here.
In 1839, the Coast and Geodetic Survey produced topographical manuscript map T-0117 and I provide a detail here of what we know today as Cattus Island:
And here is a close-up view:
The Page family still owned the land, which Joseph Page purchased in 1758. Timothy Page, likely a privateer during the American War for Independence, was the last member of the family to reside here. The “Page Sgl” marks the location of the Page Signal, part of the aids to navigation during the nineteenth century.
Timothy Page died sometime during 184o and two years later, Lewis Applegate acquired the property, but the Page dwelling had burned, so Applegate had to construct a new house.
In 1872, Frederick W. Beers prepared and published a topographical map of Ocean County:
Note that this map still shows the presence of Page Station for navigation of Barnegat Bay.
In 1875, the Coast and Geodetic Survey produced topographical manuscript map T1407:
You can that under Applegate’s ownership, the number of structures increased. I suspect Applegate’s house is the building farthest west, surrounded by a small orchard. The sawmill could be the building at the eastern end of the southernmost road. If so, then it definitely operated with steam power. This map fails to show Page Station, suggesting that the navigation aid disappeared from use between 1872 and 1875.
Regarding Shelter Cove and the Pennsylvania Salt Works, the highly detailed 1839 C&GS topographical map (T-0117) shows nothing in the area:
I hope these maps aid you in your quest.
If you are interested in the Rev War, you may want to read through the thread on the subject in the Archaeology forum. Like you, I have a passion for the American War for Independence in New Jersey. Congratulations on being so close to completing your degree at Thomas Edison State College!
Best regards,
