The interesting thing about
this map is the configuration of Chatham's Outer Beach. Monomoy
is not connected to the mainland, as it was through most of the 1900's.
Instead it is connected to North Beach.

This is the
way Cape Cod and Chatham looked to early explorers in 1675, 19 years
after the town
was settled
by William Nickerson. Notice John Sellers, the creator
of this map,
draws
Monomoy as a chain of small islands and North and South Beach are
completely
disconnected from the mainland. This looks initially
like a distortion of
early cartography
and maritime drafting. However, with what experts know
of the
geomorphology of the area
today, both representations are certainly within the
realm of possibility.

Jefferys- A Map of the Most Inhabited Part of New
England, 1755
Thomas Jefferys' map
of New England and New York was the most influential map of this
area published during the eighteenth century. Based on a variety
of sources, it provided the model for all the more accurate maps
of New York prior Simeon De Witt's map of 1802. Although
individual eighteenth-century British maps improved on Jeffery's
map in a variety of ways, the overall framework of British mapping during
this period remained essentially the same as that seen here. This
map is an excellent source of eighteenth-century place names.
Although it is
usually attributed to Jefferys, it was actually drawn by his assistant
Braddock Mead (also known as John Green). The map contains a list
of the sources used in its compilation, which was unusual in the
eighteenth century. In spite of this list, it appears that the
map was derived largely from other sources. The entire New England
portion of the map was almost certainly copied from a little-known
map by William Douglass. The part depicting
New York was probably copied from a British military survey, part
of which can be found in the Public Record Office. As Geographer to
the King, Jefferys had access to manuscript surveys of the American colonies,
some of which have been lost.
