"Racial understanding, racial sympathy, is the key to permanent WORLD PEACE." – J.A. Rogers, Sex & Race Vol. 1 (1952)
“Some dugouts resemble the lines of ancient Egyptian sea-going boats, with stem and stern upswept in curves out of the water. Their sails too look like those on these ancient types of boats. The Portuguese found African boats with sails on the Congo estuary. The sail, however, seems not to have been very common on African boats plying with sails on the Indian Ocean coast of Africa and in the tradewind zones of the Atlantic Coast. In my own work I have cited African sailing boats used by the Swahili, like the model of the 70-ton mtepe found in the Fort Jesus museum in Mombasa, Kenya. The Chinese record Africans coming with elephants to the Court of China in such ships as early as the thirteenth century, two hundred years before Columbus stumbled into the Caribbean.”
