All at once his attention became fixed upon those huge limbs, for they had awakened within him a strange memory.

He remembered having heard that, in some parts of the country, and perhaps not very far from where he then was, the natives _live in trees_.

That sometimes a whole tribe, of fifty or more, make their home in a single tree; and do so to secure themselves against savage beasts, and sometimes equally savage men.

That they build their houses upon platforms, which they erect upon the horizontal branches; and that they ascend by means of ladders, which are drawn up after them at night when they go to rest.
All this Von Bloom had heard, and all of it is positively true.

Of course the reflection occurred to him, why could _he_ not do the same?
Why could he not build a house in the gigantic nwana?
That would give him all the security he desired.
