H 
is correct, but within the distance of 2 miles 
from the reefs and Shadwan island they are 
uncertain, setting ill towards tile reefs and 
circling round them. 
The reef on which the Carnatic was lost 
is known as the Aboo Nahas, the one to 
the northward as the Horse-shoe. 
For the space of nearly a month a steady 
N. W. current was experienced passing south 
ward of Aboo Nahas, and setting westward 
and northward of the Seaul islands. Captain 
Alii Suggerv of H.H. the Khedive’s steam-ship 
Tor, states that it sets out again north and 
south of Jubal island. 
The strength of this current depends on 
the age of the moon; and at change it runs 
about 2 miles an hour. On three occasions, 
when at anchor for a week or ten days off 
Aboo Nahas. the vessel was riding with her 
head to the E. S. E. and a strong N. W. wind 
blowing the whole time. Strong under cur 
rents were found on the north side of the 
reef. 
As the Aslirafi is a first class light, and 
can be seen clearly when to the southward 
of all the reefs, with attention to its bearing, 
and Shadwan island always in sight, no 
vessel ought to be endangered. Vessels should 
pass the Ashrali lighthouse at a distance of 
from 1 to 2 miles, and then a course should 
be shaped to give the Ilorse-shoe and Aboo 
Nahas reefs a berth of from 3 to 4 miles.
