Economically the commission concluded that the existing border negatively affected Pettigo (in County Donegal) and Clones (in County Monaghan) in particular. The commission recommended several changes along the frontier: the rural protrusion of County Donegal lying between counties Tyrone and Fermanagh (including Pettigo) was to be transferred to Northern Ireland, with the Free State gaining a relatively large part of south-west Fermanagh (including Belleek, Belcoo, Garrison and Larkhill), a tract of land in southern Fermanagh, the areas either side of the Drummully (minus a thin sliver of north-western Drummully which was to be transferred to Northern Ireland), and Rosslea and the surrounding area.
