Thèse monkeys, belonging to a smaller kind of chimpanzee, which are known in Central Africa by the name of sokos^ were hideous créatures with low foreheads, bright yellow faces, and long, upright ears ; they herd in troops of about ten, bark like dogs, and are much dreaded by the natives on account of their alleged propensity to carry off young children ; there is no tèlling what predatory designs they might hâve formed against Master Jack if they had spied hîm out, but Dick*s artifice effcctually scrcened him from their observation.
