GEOGRAPHICAL DISCOVERIES. 415 
From amongst the Bapheris, the Baman- 
guatos, and the Bakones, it has been largely 
asserted that numbers of slaves are brought and 
taken in canoes, along the interior rivers, to 
the Portuguese settlements to Delagoa Bay on 
the Eastward, from whence they are shipped for 
North and South America. The districts, how-

unhealthy for Europeans, and are so thickly 
infested with the "Tsetse" fly, so destructive 
to cattle of all kinds, that few travellers have 
visited them, or at least returned to tell of their 
exploits. Towards the interior, and stretching 
along the coast to the Westward, the latest 
geographical researches have been made; in 
the former, through the discovery of the great 
salt lake, by Messrs. Oswell, King, and Living- 
stone ; and in the latter, by Dr. Livingstone's 
recent discoveries towards Angola. 
One of the greatest, and most important 
facts established by these, both in relation to 
science and the spread of Christianity, is, that 
these travellers were everywhere able to make 
their way by means of the Kaffir dialects and 
language ; and to pass from the Eastern to 
the Western coast of Southern Africa, without 
meeting any serious, or, at least, insurmount-

the greatest portions of the country, across
