ABSTRACT
Every few hundred yards the banks of the two great rivers, the Cross and Kwa Ibo, are broken to right or left by waterways, varying in breadth from good-sized creeks to streams and brooks so small that their entrances are all but hidden behind a veil of tangled lianes. One of the most important and interesting of those flowing into the Kwa Ibo is the Ubium River, the lower stretches of which were known to few, while the upper reaches, according to unanimous native testimony, were as yet unexplored.
