the inferior quadrant shows four inches and a quarter, you go right 

 east four zdms towards Jedda, if God please. Be it known that in 

 the sea of Jedda you find as you find corals in the western 



seas. 



Third Voyage from Saibdn (LoheiaJ to Sawdken*. 

 The way in which you perform a voyage from Saibdn to Sawdken 

 is the following. From the place where the pole is made with seven 

 inchest you proceed in the same manner, that is to say : first, if the 

 northern gale is strong, you steer E. S. E. and S. E. hy E. ; if there 

 is hut little wind, N. W. by W. ; but the true way from Saibdn to 

 Sawdken is by Jedda. If the northern wind blows strong you go 

 to MokaidahX, and with a small breeze to Hawateb 1 (the Hatyas) or 

 near them. Be it known, that on the sea side of the islands of Dahlek 2 

 is an amaria (shoal) and an ahja 3 , that is to say, topook* or rocks 

 which are not seen ; the most remarkable of them is the Ahja 

 Tamerkass 5 on which the water is more or less than three fathoms 

 deep ; great precaution is necessary in all these places. If the pole 

 is made by seven inches and a quarter, and the inferior quarter marks 

 seven inches, and the northern wind blows strong, you go to the 

 Hawateb, with a small northern breeze to Harmal and Bent Antar 6 , 

 or near it. If the pole is made by seven inches and a half, and if the 

 inferior quadrant shows seven inches less a quarter, and the wind 

 blows strong, you go to Bent Antar ; with a small northern wind to 

 Harmal, or it is seen at the left hand. Be it known, that from Harmal 

 to the pole or N. by W. two rhumbs and a half is a shoal Merai 

 Aari 7 called Harbobaf, of which great precaution is to be ta ken. 

 Going along the coast and the pole wanting a quarter to eight, and 

 the inferior quadrant showing six inches and a half§, and the wind 

 blowing strong, you turn to Torbet Khassus 9 or to the north side of 

 it : if the pole is eight inches and the inferior quadrant shows six 

 inches and a quarter||, and the northerly wind blows strong, you go 

 to Batn Hobdb, 10 with a small northern wind to Aantab 11 . If the pole 

 is made by eight inches and a quarter, and the wind blows strong, 

 you go to Mandel, and with a small northern breeze to Jein n or near 

 it. If the pole is made by eight inches and a quarter you go true west
