Thus, we are induced to look for the place of shipwreck, and 
in consequence for the valley of Zerrohdh^ in the quarter of 
Cape Juby ; and which opinion receives strength from the cir- 
cumstance of Ourerah being in the vicinity of Cape J uby. 
By the narrative it would appear, that seventeen days were 
employed between the place of the wreck and El Ghibldh^ an 
encampment not far from the sea-coast, in the province of the 
same name, and stated to be the southmost of the four provin- 
ces occupied by the wandering Arabs, with whom our traveller 
had communication. If this journey of seventeen days is cal- 
culated on the ordinary rate of caravan travelling, S50 or 260 
geographical miles in a straight line may be allowed ; and these 
will reach to the River Del Ouro of the Portuguese. If fif- 
teen instead of seventeen days, be the true reading, (as it ap- 
pears doubtful in the MS.) thirty miles should be deducted ; 
and the camp of El Ghihlah placed so much farther to the north- 
ward. But this will scarcely affect the general line of the route 
across the Great Desert. Caravan rate is here taken? because 
the party was so small ; it consisting only of one family, attend- 
ed by three camels ; whereas the journey across the desert was 
performed by a large party, with 2500 animals of different 
kinds ; and, moreover, was continued more than six times as 
long. The time employed in this journey is roundly given in 
months^ with the exception of three intervals of eleven, five 
and two days ; of course no accuracy is attainable. Most pro- 
bably the new moons regulated his time; but, after all, the me- 
mory was to be trusted^ and it would be unreasonable to expect 
a more consistent result than the one about to be reported. 
The total number of days may be taken at 106, unless the 
three days halt in the wood, are to be included in the gross 
number of days given for the march 
Considering that the party was composed of 115 to 120 per- 
sons, men, women and children, (Patriarch fashion), and that 
the latter classes did not always ride ; moreover that there were 
* The time given for their journey back, does not materially differ from the 
other ; it being, as well as the loose manner in which it is given (and probably could 
only be given) only a few days short of it. This tends to shorten the surplus dis- 
tance arising on the calculation which follows.
