^86 Major RennelPs Observations on the Geography 
The shipwreck took place at eight or nine hours camel tra- 
velling, (or about twenty English miles) from this valley ; and 
to the southward of it, of course, because the shipwreck happen- 
ed on the coast of Sachal^ of which the valley itself has been 
described to be the northern boundary. 
The province of Till is known to extend northward to the 
neighbourhood of Nun^ (a cape and town well known in Afri- 
can geography) ; and southward it includes the valley of Ou- 
rerah, often mentioned in the course of the narrative, and from 
whence Scott finally escaped to Nun, after four days and nights 
travelling, and a part of the fifth day ; and probably as fast as 
he could go. Allowing, then, that he went in direct distance 
100 to 110 geographical miles in a direct line, this will place 
Ourerah at that distance to the south-west of Nun, and directly 
opposite to Foriaventura^ the nearest of the Canary Islands to 
the Mainland of Africa ; and a little to the northward of Cape 
Juby How far the province of Till may extend to the south 
of Ourerah, is not known, but probably not far, as so large a 
part of it lies beyond Ourerah, to the north-east ; as also from 
the circumstance of the general trending of the coast in that quar- 
ter, as it bore on the supposed cause of the shipwreck. For 
this was doubtless the operation of a south-easterly current on the 
ship, which had carried her gradually, though imperceptibly, to- 
wards the land, all the way from the parallel of Cape Finis- 
ter re t. As her course would naturally be south-westward, that 
part of the coast which trends to the westward^ was more likely 
to have arrested the ship’s progress, than that which has a south- 
erly direction ; and this change of position takes place not far 
from Cape Juby. It seems probable, therefore, that the ship 
was stranded thereabouts ; (and, indeed, most of the shipwrecks 
happen in this quarter). Had the ship been farther to the 
south, its course would have carried it parallel to the coast, and 
within aght of land, during the preceding day ; whereas it was 
probably to the north of Cape Juby, during that day, where 
the land retires far back to the eastward, and out of sight.
