《pilgrimage to my motherland. An account of a journey among the Egbas and Yorubas of Central Africa, in 1859-60》 - 免费有声读物

Robert Campbell (1829-84) was a Jamaican-born printer, journalist, and teacher who, along with Martin Robison Delany (1812-85), made up the Niger Valley Exploring Party of 1859-60 (Library of Congress), sharing his impressions & observations as a first time visitor to areas of modern day Nigeria. This work is a forerunner of "Back to Africa" movements later spearheaded by Jamaican compatriot, Marcus Garvey Jr (who was born two years after Campbell's death). - Summary by Faith Abiola-Ellison
