B luff G rove.
A bluff grove of trees on Samahoy, generally called Arad Bluff, is a
grove of date trees on the island of Samahoy, forming a bluff near
the point. A small building stands on a mound near it. It is in
lat. 26° 16' 50" N., long. 50° 39' 52" E.
F asht al Y arron.
Fasht al Yarron, or Teignmouth Shoal. This is one of the most
extensive shoals in the Gulf, extending nearly nineteen miles in a
northerly and southerly direction, and thirteen miles wide in an easter
ly and westerly. It forms the northern boundary of the north-west
port of Bahrein, and is nearly dry in most parts. The soundings within
half a mile of it are from three to four fathoms, and it is very danger
ous, being composed of hard rock and sand. To pass clear of the
eastern end, when bound to Bahrein, keep Arad Bluff S. by W. until
you get mid-channel between the Al Yarron and Jillia Shoals. The
several parts of this shoal are in the following positions, viz. north
point lat. 26° 32' 50" N., long. 50° 30' 38" E. ; east point, lat. 26° 29'
N., long. 50° 39' E.; west point, lat. 26° 27' 20" N., long. 50°24' 20"
E. ; south-eastern point, lat. 26° 22' 20" N., long. 50° 23' 50" E.; south
western point, lat. 26° 15' 25" N., long. 50° 38' 10" E.
GENERAL DIRECTIONS FOR ENTERING THE NORTH-WESTERN PORT
OF BAHREIN.
After crossing the pearl bank (which do in the meridian of 50° 50' E.),
and sighting Arad Bluff, steer for it, keeping it S. by W. or S. by W. i W.
by compass, until you get to the southward of the Al Yarron or
Teignmouth Shoal, or, if the Portuguese fort on Bahrein is visible,
which it will be in moderately clear weather, bring it to bear SW. byS.,
when haul up about W. byN., or WNW., so as to keep the Al Yarron
Shoal nearest to you, if the wind is fair, until the fort bears SSW. i W.,
or SSW. | W., being guided by your approach to the reefs; then
steer right for it, until Arad Bluff bears SE. by E., when, if going into
the inner harbour, keep it one point open on your starboard bow, until
you near the inner harbour reef, which round. Your lead, and a good
look-out, as the reef shows plain, must be your guides, taking care not to
come undei three and a half fathoms towards the inner harbour reef,
which round pretty close, and anchor within it in three and a half or
lour fathoms, clay bottom.
The reefs generally show themselves very plainly, except when

larboui at half ebb, or last quarter ebb, as all the dangers are
