Notes
  • Depths shown by soundings and shading.
  • "The soundings are expressed in fathoms except on the shaded shoals where they are expressed in feet to 18 ft. and shew the depth at mean low water."
  • Historic Maps copy 1 has extensive ms. annotations, including note: "Note. This impression (or one like it) without Lt. Bache's soundings north of Indian Inlet was sent me in the autumn to verify & give sailing directions &c &c and, perhaps, more soundings. This sheet has false meridians. They are laid down 2 1/3 minutues too far east, which puts the land [?] much too far west."
  • Historic Maps copy 1 has ms. annotations; note in pen in upper margin: Recd. at office 22nd. 3. PM from Lt. Lee.
