I have narrated the chief incidents of our expedition.  By-the-by, the doctor took a capital sketch of one of the tree habitations, literally perched among the branches.  He had to climb a tree to take it, an easy matter in those parts, considering the immense number of tendrils to assist a person in the operation.  A big monkey was sitting on a neighbouring bough, and did not observe us, as we were hid by the thick foliage.  I have introduced the sketch at the end of the chapter.
