“ The ceremony of eating the new yams at Onitsha, on the Niger, is thus described: “Each headman brought out six yams, and cut down young branches of palm-leaves and placed them before his gate, roasted three of the yams, and got some kola-nuts and fish. After the yam is roasted, the Libia, or country doctor, takes the yam, scrapes it into a sort of meal, and divides it into halves; he then takes one piece, and places it on the lips of the person who is going to eat the new yam. ”
