{d) Settled Northern Frontiers
The whole northern frontier, that with 'Iraq and Transjordan
has been the subject of settlement in treaties {see Chapter iv’
pages 51, 52, for details), and on the Iraq and Transjordan side aii
administration controls up to the frontiers.
{e) Coastline
The whole Arabian sea coast, on both east and west, has since the
earliest times been infamous to sailors for its inaccessibility owing to
shallowness and reefs and its foul coral anchorages, conditions which
apart from any other factors, help to maintain the isolation of
Saudi Arabia. (For further detail of Coastline see Chapter V, page 79)
Sloops of the Royal Navy patrol both the Red Sea and the
Persian Gulf, and call at their ports periodically.
