We will leave our friends to get on shore, discharge the boats, and start them on their return to M'tesa, while we repeat some of their conversation during the voyage. While they were returning from Ripon Falls to Rubaga, Doctor Bronson told Fred he would like to have him read up the description of the West Coast of Africa on the first opportunity, and be able to give a brief account of it during their southward voyage. The halt at Usavara gave him the needed time, which he improved to advantage. They were not provided with a large number of books on that part of the country, but, fortunately, there were enough for his purpose. "The West Coast of Africa," said he, "is properly comprised between the Desert of Sahara and Cape Negro, the latter being about latitude 19° south. There are three divisions of this region, known as Senegambia, Upper Guinea, and Lower Guinea, and each of them comprises several native states, and nearly as many European possessions." "You can read all that in an encyclopædia or any good geography," said Frank, with a slight laugh. "Of course you can," retorted Fred; "but if you don't happen to have read it, and no one has told you, it is pretty certain to be news to you." Frank admitted the correctness of Fred's statement and the story was continued. "The English have a settlement at Bathurst, on the Gambia River, and there are other small settlements near it. There is another settlement, called Sierra Leone, on a peninsula eighteen miles long by twelve in width. The Danes and Dutch formerly had settlements along the coast, but they ceded them to England, the former in 1850, and the latter in 1872. The Spaniards once held quite an extent of coast, but at present their only possession is the island of Fernando Po, which they use as a convict station. "The Portuguese still have control of a large extent of country--at least, nominally--and they have several small ports where they do quite a trade in palm-oil, india-rubber, ivory, gold, and other products of Africa. They formerly dealt in slaves, but have followed the fashion of England and abolished the slave-trade--at least, in name. But a great deal of the traffic is kept up at the present time, the slaves being taken south from interior stations in the Portuguese possessions and sold to the Kaffirs, instead of being brought to the coast.
