492 Wanderings in Eastern Africa, 
consent to sell each other into bondage; even Africans 
are not sufficiently degraded for that. By far the 
largest number of slaves are obtained from the southern 
region, from the Wamakua, Wangindo, Waiau, and 
Wanyassa tribes; but almost all the rest send supplies 
at some time or other, more or less. 
Now a word or two as to the markets to which 
the slaves are conveyed. These are both home and 
foreign. All the towns and villages upon the east 
coast are supplied with slaves from the interior ; and 
at most of the larger towns — Kiloa, Zanzibar, Mom- 
basa, Malinde, Lamu, etc. — slaves were sold in 1872 
in the public market-places ; but Sir B. Frere's treaty, 
we believe, has put an end to this for the time. The 
foreign markets were Madagascar, the Comoro islands, 
Arabia, and Persia, the two latter, it must be observed, 
in spite of treaties forbidding the traffic to those 
countries ! 
The great extent to which the traffic was being 
carried on has now become a matter of public 
notoriety ; all that Dr. Livingstone and others had 
said having been more than confirmed by the letters 
of the correspondents who accompanied Sir B. Frere, 
and by the reports of Sir B. Frere himself Zanzibar 
alone imported about 20,000 slaves annually ; a brisk 
trade was being carried on between Mozambique 
and Madagascar ; many thousands were conveyed to 
the Persian Gulf ; and if to them we add the Red 
Sea and the Nile or Egyptian trade, it has been 
estimated that the number of slaves brought to the 
market would amount to something like 70,000 
annually ! Bat there is a matter of great importance 
which must not be overlooked in the consideration
