“ The river, or rather the bed of it, is here of great width, and most frightful depth, lined on all sides with huge masses of black rock of every imaginable form. The flood that roars through them is seen only at intervals; here in a full heavy sheet of green transparent water, falling straight and unbroken; there dashing along a narrow channel, with a violence that makes one dizzy to see and hear. ”
