an, marabout or
saint. Major Denham afterwards learned that he had penetrated across
Africa as far as Nyffe, on the Niger, where he fell a victim, not to
any hostility on the part of the natives, but to disease and the
climate. A young man was even met with, who professed to be his son,
though there were some doubt as to the grounds of his claim to that
character.

The association, when their expectations from Horneman had failed,
began to look round for other adventurers, and there were still a
number of active and daring spirits ready to brave the dangers of
this undertaking. Mr. Nicholls, in 1804, repaired to Calabar, in the
Gulf of Benin, with the view of penetrating into the interior by this
route, which appeared shorter than any other, but without any
presentiment that the termination of the Niger was to be found in
that quarter. He was well received by the chiefs on that coast, but
could not gain much information respecting that river, being informed
that most of the slaves came from the west, and that the navigation
of the Calabar stream, at no great distance was interrupted by an
immense waterfall, beyond which the surface of the country became
very elevated. Unfortunately, of all the sickly climates of Africa,
this is perhaps the most pestilential, and Mr. Nicholls, before
commencing his journey, fell a victim to the epidemic fever.

Another German named Roentgen, recommended also by Blumenbach,
undertook to penetrate into the interior of Africa by way of Morocco.
He was described as possessing an unblemished character, ardent zeal
in the cause, with great strength both of mind and body. Like
Horneman, he made himself master of Arabic, and proposed to pass for
a Mahommedan. Having in 1809 arrived at Mogadore, he hired two
guides, and set out to join the Soudan caravan. His career, however,
was short indeed, for soon after his body was found at a little
distance from the place whence he started. No information could ever
be obtained as to the particulars of his death, but it was too
probably conjectured that his guides murdered him for the sake of his
property.

CHAPTER X.

We are now entering upon the narrative of a series of the most
extraordinary adventures which ever befel the African travellers, in
the person of an illiterate and obscure seaman, of the name of Robert
Adams, who was wrecked on the western coast of Africa, in the
American ship Charles, bound to the isle of Mayo, and who may be said
