THE EASTERN COAST. 
Hon the neighbouring islands of Pemba, Zanzibar, 
and Monfia. 
The coast of Africa, from Cape Guardafui to 
the Straits of Babelmandel, was found by Lord 
Valentia and Mr Salt to be inhabited by the tribes 
of the Somauli, who are an uncommonly active, 
industrious, and commercial race. Berbera is a 
large town situated upon this coast, where an ex- 
tensive fair is annually held, and resorted to by 
caravans from a great distance in the interior. 
Lord Valentia saw some who came from the coun- 
try in which the Bahr-el-Abiad takes its rise, and 
conceives that this would be the best channel for 
exploring the source of that great river. Gum 
arabic, myrrh, and frankincensej are the principal 
exports from this coast*
