W. Holman Bentley, Life on the Congo
“ Another custom helps us. When a slave has a bad master, who ill-treats him, and who may, perhaps, intend to sell him on the coast, the slave will run away to a chief who has a good name in the country, and tell him that he has come to be his slave. If the chief is willing, he orders a goat to be killed; the chief and the slave eat goat together; the covenant is made, and the new slave is called a ‘goat.’ His old master hears that his slave is with the other chief, and comes with bluster to demand him back. ”
