care, not in a house. And my mother lived anywhere, so
long as when night came she was above the ground.

My mother was old-fashioned. She still clung to her
trees. It is true, the more progressive members of our
horde lived in the caves above the river. But my
mother was suspicious and unprogressive. The trees were
good enough for her. Of course, we had one particular
tree in which we usually roosted, though we often
roosted in other trees when nightfall caught us. In a
convenient fork was a sort of rude platform of twigs
and branches and creeping things. It was more like a
huge bird-nest than anything else, though it was a
thousand times cruder in the weaving than any
bird-nest. But it had one feature that I have never
seen attached to any bird-nest, namely, a roof.

Oh, not a roof such as modern man makes! Nor a roof
such as is made by the lowest aborigines of to-day. It
was infinitely more clumsy than the clumsiest handiwork
of man--of man as we know him. It was put together in a
casual, helter-skelter sort of way. Above the fork of
the tree whereon we rested was a pile of dead branches
and brush. Four or five adjacent forks held what I may
term the various ridge-poles. These were merely stout
sticks an inch or so in diameter. On them rested the
brush and branches. These seemed to have been tossed on
almost aimlessly. There was no attempt at thatching.
And I must confess that the roof leaked miserably in a
