Hey I have one of these in my yard!
During the age of sail, the White Pine’s high quality wood was valued for masts, many trees were marked in colonial times with the broad arrow, reserving them for the British Royal Navy. An unusual large, lone, white pine was found, in coastal South Carolina along the Black River (far from where they normally grow) and the king's mark was put upon this particular tree, giving rise to the town of Kingstree. The wood was often squared immediately after felling to fit in the holds of ships better
The British soon built special barge-like vessels which could carry up to 50 pine trunks destined to be ship masts. A 100’ mast was about 3’X3’ at the butt and 2’X2’ at the top, while a 120’ mast was a giant 4’X4’ at the bottom and 30” at the top.
