Journal of my journey over the mountains by George Washington is available on Project Gutenberg. Very interesting read with explanatory annotations by the editor, and maps.
I visit Gutenberg daily and often find literary gems, including the original Tom Swift books from my childhood.
Uh oh. Is the divide line aa or aC? One of those must be a fence!!!!!!!!!!!!!!!!
That's back when surveying was a prominent profession to be engaged.
I have read that Washington became wealthy man by marrying Martha. She was a widow of a heir of a planter family that owned a lot of land and slaves. She received a 1/3 of his estate (children 2/3)and when she married GW, he controlled her estate and the children's. He already had land holdings from his family and was educated as a surveyor. This plat was probably part of that process.
Jump started my old laptop last night that hasn't been used for a few months and noticed the Gutenberg Project tab in the top bar menu.
