Documentary History of the State of New York, Vol. I
As the Legislature in 178S thought proper to annex it to the town of East Hampton, it will, in these This Island is distant from the town 10 miles: and Notes, be considered as a part of that Township. is, besides, an
Island called Rom (or Rum) Island, which belongs to
it,
from Long Island shore about 3. It is assessed for about one sixth of the value of the Township. The shore on the North side of East Hampton is rocky and indented with bays, coves, and creeks,
which lead into Ponds abounding with shell and scale fish, and are harbours for small vessels. Westerly, the town is bounded by South Hampton.
The line between these two towns was in contention from the first settlement till 1695, when it was, finally, fixed where it now is, by persons mutually chosen by the two Towns. It begins at the sea shore on the south side, and crosses the eastern branch of the Island, to the North side & leaves
but a small part of the houses, at Sag Harbor on the East Hampton side.
This line is about
miles
in length, & was fenced about the year 1664 in order to keep the Southampton horses &c. from crossing over the bounds.
This line is now much farther to the Eastward than where it was fixed by the
General Assembly of Connecticut about 1660 to whose decision it was then referred.
The settlement of Sag Harbor is mostly in Southampton Township, and is a thriving place.
