For an instant, as I passed the dark one with the fat cheeks who was wheeling a bicycle, I caught her smiling, sidelong glance, aimed from the centre of that inhuman world which enclosed the life of this little tribe, an inaccessible, unknown world to which the idea of what I was could certainly never attain nor find a place in it. Wholly occupied with what her companions were saying, this young girl in her polo-cap, pulled down very low over her brow, had she seen me at the moment in which the dark ray emanating from her eyes had fallen on me? In the heart of what universe did she distinguish me? It would have been as hard for me to say as, when certain peculiarities are made visible, thanks to the telescope, in a neighbouring planet, it is difficult to arrive at the conclusion that human beings inhabit it, that they can see us, or to say what ideas the sight of us can have aroused in their minds.
