float, as large as a child's head, formed of an extremely light wood
called ambatch (Aanemone mirabilis) that is of about half the specific
gravity of cork. The extreme end of the short harpoon is fixed in the
point of a bamboo about ten feet long, around which the rope is twisted,
while the buoy end is carried in the left hand.

The old Abou Do, being resolved upon work, had divested himself of his
tope or toga before starting, according to the general custom of the
aggageers, who usually wear a simple piece of leather wound round the

the old sea-god ruled the monsters of the deep; and as the tall Arab
patriarch of threescore years and ten, with his long gray locks flowing
over his brawny shoulders, stepped as lightly as a goat from rock to
rock along the rough margin of the river, I followed him in admiration.

After walking about two miles we noticed a herd of hippopotami in a pool
below a rapid. This was surrounded by rocks, except upon one side, where
the rush of water had thrown up a bank of pebbles and sand. Our old
Neptune did not condescend to bestow the slightest attention when I
pointed out these animals; they were too wide awake; but he immediately
quitted the river's bed, and we followed him quietly behind the fringe

About half a mile below this spot, as we clambered over the intervening
rocks through a gorge which formed a powerful rapid, I observed, in a
