Sahara after 1839 g. Tilo

you are: Sahara after 1839

In same time other French officer, Tilo about which work round lake Chad we already spoke, was engaged in liquidation of a white stain further on the east. In 1912 it has been appointed by the chief of garrison in Kaneme, whence has spent a number of successful military operations against senussitov Tibesti. Later it investigated considerable territories in Borku, Ennedi and across Tibesti mountains, and in 1917 through Vadai and Darfur has returned back. Its work was extremely successful. Throughout all way Tilo has managed precisely to define geographical co-ordinates of some points. Extremely valuable results of its travel is better to summarise its words:

' the Great geographical problem of an ancient water communication between lake Chad and river Nile pools is definitively resolved now; the mountainous barrier surrounds pool of lake Chad from ridge Tummo in the north to Dzhebel-Marra in the southeast, covering file Tibesti, plateau Zhef-Zhef, tablelands Erdi and Ennedi, hills Zagavy and mountains of the western Darfur. The lowest marks are in a lake Chad hollow on plains of the lowland laying to the northeast from lake Chad... The Third large fruit of works of expedition is revealing of the geographical form of large hills, type Tibesti and Ennedi, hitherto appearing on cards of Africa in very imperfective aspect, and also detection of other large hills known under name Erdi, a connecting link playing a role between two files mentioned above. The material collected by us allows us to specify to geographers in existence in the centre of Libyan desert also other hills, namely a Dzhebel-ALE-auinat, laying in 150 miles to the southeast from an oasis Cufra '.
