HISTORY   OF   THE   TOWN   OF   BROOKLINE  43

Originally  the  Slip  was  unincorporated  land;  it  having,  for  some
unknown  reason,  failed  to  be  included  in  either  the  Dunstable  or  Ma-
sonian  grants.  In  1769  its  southern  half  was  incorporated  as  a  part  of
Brookline.  In  1776  its  northern  part,  together  with  the  Duxbury  School
Farm,  were  incorporated  into  a  township  under  the  name  of  Duxbury.
Duxbury  had  but  a  short  existence;  and  when  Milford  was  incor-
porated in  1794,  it,  with  the  northern  part  of  the  Mile  Slip,  was  covered
into  the  territory  of  the  latter  town.  Thus  the  entire  original  area  of  the
Mile  Slip  is  today  included  within  the  boundary  lines  of  Brookline  and
Milford.
The   Triangular   Tract    of   Land    Derived  from  Townsend,  Mass.,
and  the  Old  North  Boundary  Line  of  Townsend.
