The limits of undisputed Ajman territory in the Wadi Hatta
are as follows.

The line starts at the peak of Jabal Abu Faraj and runs
eastwards along the watershed between the Wadis Qor and Hatta to
a point north of Jabal Mussaya. The line then runs straight
south across the Wadi Hatta to Jabal Mussaya and on along the
wall at Jabal Mussaya and thence by the watershed between the
Wadis running to Hajarain and those running to Masfut to the
peak of Jabal Umm an Nasur. From Umm an Nasur the line runs
west to the head of Wadi Ghalfarom the south, the wadi
belonging to Masfut. The limit continues northwards down the
watershed to the west of Wadi Ghalfa to Hasat Mayzoul and
on to the wall at Jabal Laim. Thence it runs westwards along
the summit of Jabal Mizaira and goes west to the western tip
of the mountain and on down the Wadi Khurus between Al Jazir
and Khtaim Ar Rahma, and on to Subaigha and Milaiha the latter
two places being outside the limits of undisputed territory.
From Milaiha the line goes east to the head of Wadi Sawamia
and on to the peak of Jabal Abu Faraj.
