there are no islands or open spaces, birds also are not to be seen.

At one place on the Sankuru I noticed a small kind of hippopotamus in a herd of twenty-three, none of which were larger than an Alderney cow. Sometime later in the Lualaba district I saw a herd of seventeen of these small hippos. To anyone acquainted with the habits of this animal, it is impossible to suppose that these could have all been young hippos together, and leads to the conclusion that they must have been an, as yet, undescribed species. They were considerably larger than the slightly-known Liberian hippopotamus, and not half the size of the common hippopotamus. On both occasions I could easily have shot some, but since, except by great luck, I should have been unable to pick them up I refrained from firing, hoping to come across them again under more favourable circumstances.
