rust he will realize the fortune which he so well
deserves to earn. Had Mr. Sunley performed the same experiment on the
mainland, where people would have flocked to him for the wages he now
gives, he would certainly have inaugurated a new era on the East Coast of
Africa. On a small island where the slaveholders have complete power
over the slaves, and where there is no free soil such as is everywhere
met with in Africa, the experiment ought not to be repeated. Were Mr.
Sunley commencing again, it should neither be in Zanzibar nor Johanna,
but on African soil, where, if even a slave is ill-treated, he can easily
by flight become free. On an island under native rule a joint
manufacture by Arabs and Englishmen might only mean that the latter were
to escape the odium of flogging the slaves.

On leaving Johanna and our oxen for a time, H.M.S. "Orestes" towed us
thence to the mouth of the Rovuma at the beginning of September. Captain
Gardner, her commander, and several of his officers, accompanied us up
the river for two days in the gig and cutter. The water was unusually
low, and it was rather dull work for a few hours in the morning; but the
scene became livelier and more animated when the breeze began to blow.
Our four boats they swept on under full sail, the men on the look out in
the gig and cutter calling, "Port, sir!" "Starboard, sir!" "As you go,
sir!" while the black men in the bows of the others shouted the practical
equivalents, "Pagombe! Pagombe!" "Enda quete!" "Berane! Berane!"
Presently the leading-boat touches on a sandbank; down comes the
fluttering sail; the men jump out to shove her off, and the other boats,
shunning the obstruction, shoot on ahead to be brought up each in its
turn by mistaking a sandbank for the channel, which had often but a very
little depth of water.

A drowsy herd of hippopotami were suddenly startled by a score of rifle-
shots, and stared in amazement at the strange objects which had invaded
their peaceful domains, until a few more bullets compelled them to seek
refuge at the bottom of the deep pool, near which they had been quietly
reposing. On our return, one of the herd retaliated. He followed the
boat, came up under it, and twice tried to tear the bottom out of it; but
fortunately it was too flat for his jaws to get a good grip, so he merely
damaged one of the planks with his tusks, though he lifted the boat right
up, with ten men and a ton of ebony in it.

We slept,
