James Richardson,
Narrative of a Mission to Central Africa Performed in the Years 1850-51…
“ It is quite clear that these Daggera inhabit all the northern line of Bornou, from Zinder to Kuka; skirting, in fact, all the left of our route. They join the Damerghou territory, and thus extend from that province west to Kanem, and the route of Bornou east. The Tuaricks are ever located on the confines of the desert. Here they roam free, and rob and plunder where they have opportunity, or when the princes of Bornou and Soudan cannot check them.Our people gnaw the doom fruit, but it is just like gnawing the bark of a tree, slightly flavoured with some aroma. ”
