1857 chart of western Raritan Bay showing the location of the mouth of Cheesequake Creek and its proximity to part of Capt. James Morgan’s property holdings.

The numbers shown on the bay are “The soundings are expressed in feet, and show the depth at mean low water the plane of reference.” In other words, how deep is the bay at that location.
