EARLY MAN IN BRITISH EAST AFRICA 
higher stages such as are represented by the beautiful polished 
celts, &c., of later Neolithic times in Europe. 
It must also be remembered that in Europe a Bronze Age 
intervened between the last stone implement period and the 
coming of iron. There is no record of such a period in Africa, 
but it is believed that the natives of the South Congo worked 
the great copper deposits of the Katanga region longer than 
we are apt to think. Another factor which had a profound 
influence in Europe was the occurrence of the Ice Age, wdiich 
could not have appreciably affected the human inhabitants of 
Central Africa. 
The South African implements have been divided by Dr. 
Peringuey into three groups which may be termed : 
Type 1. — Palaeolithic. 
Type 2. — South African Neolithic. 
Type 3. — Later Neolithic — which corresponds to what has 
generally become known as the true Neolithic 
in Europe. 
Type 1 will probably be found in East Africa and 
Uganda, and possibly the basalt scrapers recently discovered 
by Dr. Oswald near Karungu will be found to belong to 
this period. 
The majority of the implements discovered in East Africa, 
howrever, appear to belong to Type 2, and consist of arrow-heads 
and scrapers. It is curious that no bouchers or primitive stone 
axes have been found, as they are well known in South Africa ; 
but they will doubtless turn up as more people turn attention 
to the quest for these relics. 
With regard to Type 3, it is represented in Europe 
by beautifully worked arrow-heads, with tangs and stone axes, 
or celts ground or rubbed down until a smoothly worked edge 
was obtained, and also sometimes perforated for the handle. 
The only articles found in British East Africa which con- 
form to this type are the two perforated stones called Kwe in 
South Africa, and which have been previously mentioned, and 
the stone bowl (or mortar) found at Naivasha. Certain old 
steatite pipe bowls still occasionally seen, the possession of 
chiefs in Kavirondo, may be survivals of this class of industry ;
