ukawa. Here he had to remain four months, greatly troubled by
financial difficulties, and finding that a considerable portion of his
property had been stolen by the rascality of one of his servants. His
health, too, was greatly shattered.

It was not till the 4th of May that, in company with a Fezzan merchant,
Kolo, he commenced his return journey, with a small caravan, towards
Tripoli. At Barruwa they laid in a supply of dry, ill-smelling fish,
which constitutes the most useful article of exchange in the Tebu
country. The region to his right, over which he had previously passed,
was now entirely covered with water from the overflowing of the Chad,
which had submerged several villages.

He met with no unusual adventures during his long, tedious journey
northward across the desert.

At Mourzouk he had the pleasure of meeting Mr Frederick Warrington. He
here remained six days, discharging some of his servants, and among them
his faithful Gatroni.

Some tribes of Arabs had here rebelled against the Turks, and he was in
some danger while in their hands. Escaping, however, from them, he
reached Tripoli in the middle of August, and, embarking at the end of
four days, arrived safely, on the 6th of September, in London.

Although much of the country he had passed over was already known, no
previous African traveller more successfully encountered and overcame
the difficulties and dangers of a journey through that region.

The most important result of his adventurous journey was the discovery
of a large river, hitherto unknown, falling into the Chad from the
south, and of the still larger affluent of the Quorra, the mighty Binue,
which, rising in the far-off centre of the continent, flows through the
province of Adamawa.

The courage and perseverance of Dr Barth, while for five years
travelling many thousand miles, amidst hostile and savage tribes, in an
enervating climate, frequently with unwholesome or insufficient food,
having ever to keep his energies on the stretch to guard himself from
the attacks of open foes or the treachery of pretended friends, have
gained for him the admiration of all who read his travels, and place him
among the first of African travellers.
