London: Church Missionary Society, 1927. Paperback. ix, 113p., sewn signatures, illustrated with line map and inserted photographic plates as called for. Softbound in 7x5 inch reddish wraps with black titling. Two of three loops of thread are intact but the central loop has disappeared. Extremities are abraded; spine panel was glued fast to back of textblock and, having been opened throughout, became badly wrinkled, rendering spine titling nearly illegible. That said, a handleable, readable copy.
