against us. Night closed in, and the wind drew more ahead, so we
had to take in sail. Then came a calm, and we rowed and sailed as
occasion offered; and it was four in the morning when we reached
the village of Kisslwoi, not having made more than three miles in
the last twelve hours.

MATABELLO ISLANDS.

At daylight I found we were; in a beautiful little harbour,
formed by a coral reef about two hundred yards from shore, and
perfectly secure in every wind. Having eaten nothing since the
previous morning, we cooked our breakfast comfortably on shore,
and left about noon, coasting along the two islands of this
group, which lie in the same line, and are separated by a narrow
channel. Both seem entirely formed of raised coral rock; but them
has been a subsequent subsidence, as shaven by the barrier reef
which extends all along them at varying distances from the shore,
This reef is sometimes only marked by a. line of breakers when
there is a little swell on the sea; in other places there is a
ridge of dead coral above the water, which is here and there high
enough to support a few low bushes. This was the first example I
had met with of a true barrier reef due to subsidence, as has
been so clearly shown by Mr. Darwin. In a sheltered archipelago
they will seldom be distinguishable, from the absence of those
huge rolling waves and breakers which in the wide ocean throw up
a barrier of broken coral far above the usual high-water mark,
while here they rarely rise to the surface.

On reaching the end of the southern island, called Uta, we were
kept waiting two days for a wind that would enable us to pass
