en, intending to purchase the goods ordered by Sekeletu in England with
his own money, and, on his return, repay himself out of the price of the
ivory.

He consented, somewhat unwillingly, to take Sekwebu with him to England.

After waiting about six weeks at Quillimane, HM brig "Frolic" arrived,
on board which he embarked. A fearful sea broke over the bar, and the
brig was rolling so much that there was great difficulty in reaching her
deck. Poor Sekwebu looked at his friend, asking: "Is this the way you
go?" The doctor tried to encourage him; but, though well acquainted
with canoes, he had never seen anything like it.

Having been three and a half years, with the exception of a short
interval in Angola, without speaking English, and for thirteen but
partially using it, the doctor found the greatest difficulty in
expressing himself on board the "Frolic."

The brig sailed on the 12th of July for the Mauritius, which was reached
on the 12th of August. Poor Sekwebu had become a favourite both with
men and officers, and was gaining some knowledge of English, though all
he saw had apparently affected his mind. The sight of a steamer, which
came out to tow the brig into the harbour, so affected him that during
the night he became insane and threatened to throw himself into the
water. By gentle treatment he became calmer, and Dr Livingstone tried
to get him on shore, but he refused to go. In the evening his malady
returned; and, after attempting to spear one of the crew, he leaped
overboard and, pulling himself down by the chain cable, disappeared.
The body of poor Sekwebu was never found.

After remaining some time at the Mauritius, till he had recovered from
the effects of the African fever, our enterprising traveller sailed by
way of the Red Sea for old England, which he reached on the 12th of
December, 1856.

Dr Livingstone, in the series of journeys which have been described,
had already accomplished more than any previous traveller in Africa,
besides having gained information of the greatest value as regards both
missionary and mercantile enterprise. He had as yet, however, performed
only a small portion of the great work his untiring zeal and energy have
prompted him to undertake.
