Generally so styled at the present day, but Bedouins sometimes call it Dohat-al-Qatar; and it seems to have been formerly better known as Bida' (Anglice Bidder): it is the chief town of Qatar and is situated on the eastern side of that peninsula, about 63 miles south of its extremity at Ras Rakan and 45 miles north of Khor-al Odaid Harbour. Dohah stands on the south side of a deep bay at the south-western corner of a natural harbour which is about 3 miles in extent and is protected on the north-east and south-east sides by natural reefs. The entrance, less than a mile wide, is from the east between the points of the reefs; it is shallow and somewhat difficult, and vessels of more than 15 feet draught cannot pass. The soundings within the basin vary from 3 to 5 fathoms and are regular: the bottom is white mud or clay.
