wlio cannot read, the whole system of our influence appears to 
rest, that innovators ought to be made to propose their new 
measures as the Locrians did new laws—-with ropes around them 
necks. 
Probably the “boguera” was only a sanitary and political 
measm’e; and there being no continuous chain of tribes practising 
the rite between the Arabs and the Bechuanas, or Caffres, and as 
it is not a religious ceremony, it can scarcely be traced, as is 
often done, to a Mahometan source. 
A somewhat analogous ceremony (boyale) takes place for 
young women, and the protegees appear abroad drilled under the 
surveillance of an old lady to the carrying of water. They are 
clad dmring the whole time in a dress composed of ropes made of 
alternate pumpldn-seeds and bits of reed strung together, and 
wound round the body in a figure-of-eight fashion. They are 
inm^ed in this way to bear fatigue, and carry large pots of water 
under the guidance of the stern old hag. They have often scars 
from bits of burning charcoal having been applied to the forearm, 
which must have been done to test their power of bearing pain. 
The Bamangwato hills are part of the range called Bakaa. 
The Bakaa tribe, however, removed to Kolobeng, and is now 
joined to that of Sechele. The range stands about 700 or 800 
feet above the plains, and is composed of great masses of black 
basalt. It is probably part of the latest series of volcanic rocks 
in South Africa. At the eastern end these hdls have cmdous 
fungoid or cup-shaped hollows, of a size which suggests the idea 
of craters. Within these are masses of the rock crystallized in 
the columnar form of this formation. The tops of the columns 
are quite distinct, of the hexagonal form, like the bottom of the 
cells of a honeycomb, but they are not parted from each other as 
in the Cave of Fingal. In many parts the lava-streams may be 
recognised, for there the rock is rent and split in every direction, 
but no sod. is yet found in the interstices. When we were sitting 
in the evening, after a hot day, it was quite common to hear 
these masses of basalt split and fall among each other with the 
peculiar ringing sound which makes people believe that this rock 
contains much don. 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
