from the history of that vast county in Northern Maine, the Aroostook War, an earlier lumber/border dispute, involving secret maps, etc...

"The Aroostook War, also called the Pork and Beans War, the Lumberjack's War or the Northeastern Boundary Dispute, was an undeclared, bloodless North American "war" that occurred in the winter of 1838 and early spring of 1839...The majority of early Aroostook River Valley settlers were from "over-home", that is, from the St. John River Valley and were typically British citizens. The population swelled in the wintertime when lumbermen were freed from farmwork to "long-pole" up the St. John River to the valley. These migrant lumbermen were a particular point of tension for the Americans. Some eventually settled permanently in the valley and improved their land claims. Most settlers found themselves too remote from the authorities to apply formally for land, and since the boundary was ambiguous it was uncertain which government was in authority, anyway. Disputes heated up as factions maneuvered for control over the best stands of trees in the valley."
