"But there is a boundary to their realm—the boundary of the dark, horrible, lofty forest. There, like the waves about the Hebrides, the low underwood is agitated continually. But there is no wind throughout the heaven. And the tall primeval trees rock eternally hither and thither with a crashing and mighty sound. And from their high summits, one by one, drop everlasting dews. And at the roots, strange poisonous flowers lie writhing in perturbed slumber. And overhead, with a rustling and loud noise, the gray clouds rush westwardly forever until they roll, a cataract, over the fiery wall of the horizon. But there is no wind throughout the heaven. And by the shores of the river Zäire there is neither quiet nor silence.
