These however, are not scored and grooved as
are those exposed to the eroding influences of
ceaseless ocean waves; they are cleanly fractured,
th their external angles only exhibiting a rough
polish or roundness which I take to be clear
signs that at some remote time they were exposed
to waves of great power. Besides> the condkion
° f the rocks at the water-line confirms this theory.
btill, it is strange that the lake should have
been rising steadily ever since living men can
, e“ an that those rocks of Mpimbwe
should bear witness to the lake’s subsidence.

south some fifteen or sixteen miles, we arrived
at Mkerengi Island, in the bay of Kirando; the
large island of Makokomo lying to west of us

a mile off. The natives of these parts are very
amiable, though extremely superstitious. At
the north-west end of Makokomo there is another
lately submerged island. Close to the south-west
end is a group of inhabited islands, Kankamba
and Funeh being the largest and most fertile,
Kirando is situated among other large villages
in what appears to be a plain, hemmed in on
the east by the continuation of the mountain-
ridges which we lost sight of when we left
Karema Bay. The truncated cone of Chakavola
terminates the ridge of Mpimbwe and lies northeast
from Mkerengi.
Continuing our voyage southerly along the
cbast between the isles of Kankamba and its
brothers and the shore of the mainland, and
passing a couple of creeks running deep in-shore,
we came to Cape Muntuwa. From this cape to
Msamba Island, where we encamped, the lake
is edged by one successive series of gigantic
blocks and crags of granite. Rock rises above
rock, and fragment above fragment. Here towers
a colossal mass the size of a two-storied house,
bearing upon it a similar mass perhaps entire,
but more probably split with a singularly clean
and fresh fracture, and there springs up from
the surrounding chaos a columnar block like a
closed hand with outstretched fore-finger— but
everywhere there is the same huge disarray,
ruin, and confusion.
