North Weft (or between the Weft and North) hes the Country 
of Yarba : and eight days farther Weft, that of Affow. Now 
the countries of Yarra and Yaffon, will be found in Dehfle's 
Map of Senegal (1726), nearly in the pofition that Yarha 
and Affow take in refpeft of Gonjah ; fuppofing D'Anville's 
Conche to be meant for it. It is extremely difficult to affign a 
ratio for the decreafe of the horizontal diftance, on fo extended 
a line as ninety-feven days journey ; and therefore it v/ould be 
lofing time to attempt it. Gonjah, by circumftances, is about 
eight hundred and feventy miles from Caflina, which allows only 
nine miles for each day. I therefore conclude that the road is 
very circuitous. 
Gonjah is reported by the Shereef to be forty-fix days jour-

points of the line of diftance are correftly kaown. The Reader 
muft therefore determiine for himfelf. Of this fpace of forty-
