"What distance have we traversed to-day?" asked

The doctor took his bearings, by means of lunar observations,
and consulted the excellent map that he had with
him for his guidance. It belonged to the Atlas of "Der
Neuester Endeckungen in Afrika" ("The Latest Discoveries
in Africa"), published at Gotha by his learned friend
Dr. Petermann, and by that savant sent to him. This
Atlas was to serve the doctor on his whole journey; for it
contained the itinerary of Burton and Speke to the great
lakes; the Soudan, according to Dr. Barth; the Lower
Senegal, according to Guillaume Lejean; and the Delta of
the Niger, by Dr. Blaikie.
Ferguson had also provided himself with a work which
combined in one compilation all the notions already acquired
concerning the Nile. It was entitled "The Sources
of the Nile; being a General Survey of the Basin of that
River and of its Head-Stream, with the History of the
Nilotic Discovery, by Charles Beke, D.D."
He also had the excellent charts published in the
"Bulletins of the Geographical Society of London;" and
not a single point of the countries already discovered
could, therefore, escape his notice.
Upon tracing on his maps, he found that his latitudinal
route had been two degrees, or one hundred and
twenty miles, to the westward.
