Hasa.
1. General. —This region is bounded on the north by the
southern boundary of the Principality of Kuwait and on
the south by the northern frontier of Qatar and the desert
ot Jafura; on the east by the sea and on the west by the
desert of Summan.
It is a province in the dominions of Ibn Saud.
The greater part of Hasa consists of steppe and desert
rising westward from a low coast. The stony ridges of the
Summan running more or less parallel with the coast of
the Gulf intervene between Hasa and the belt of the
Dahana desert which separates it from Nejd. Shallow
wells of drinkable water are fairly numerous.
The Hasa and Qatif oases in the southern part of the
pro\ ince are the only fertile and well watered tracts in
the area.
- ■ Districts Hasa Oasis. —This is an oasis of great fer
tility separated from the Gulf at Oqair by over 30 miles of
desert. It contains the two large towns of Hofuf and
Mubarraz. The mass of the cultivated territory extends
for about, 12 miles to the east of Hcfuf and Mubarraz, but
there are detached blocks of cultivation further to the
noth.
The most remarkable physical feature of the Hasa Oasis
is tlie abundance of water in the cultivated area, from a
very large number of springs, some of which are hot. Much
or the area is marshy and there are two small lakes at
Birkat-ul-Asfor, 12 miles E.N.E. of Hofuf, and Birkat
Umm-ul-Mahza, 7 miles east of Ayim. The springs are
x? i drama S e of the highlands of Nejd passing under
the Dahana. &
The oasis extends for about 30 miles noth and south
and 21 miles east and west.
It contains a number of villages.
