Several large masses, in splitting thus
by the cold acting suddenly on parts expanded by the heat of the day,
have slipped down the sides of the hills, and, impinging against each other,
have formed cavities in which the Bakaa took refuge against their enemies.
The numerous chinks and crannies left by these huge fragments
made it quite impossible for their enemies to smoke them out,
as was done by the Boers to the people of Mankopane.
This mass of basalt, about six miles long, has tilted up the rocks on both
the east and west; these upheaved rocks are the ancient silurian schists
which formed the bottom of the great primaeval valley,
and, like all the recent volcanic rocks of this country,
have a hot fountain in their vicinity, namely, that of Serinane.
In passing through these hills on our way north we enter a pass
named Manakalongwe, or Unicorn's Pass. The unicorn here
is a large edible caterpillar, with an erect, horn-like tail.
The pass was also called Porapora (or gurgling of water),
from a stream having run through it.
