Thomason Foss, a water-fall of singularly romantic character … generally forms the extent of the stranger’s scramble, the valley being completely closed in by rocks over which the water falls; but my making a circuit over the rocks to the left, the course of the stream above the fall may be attained; and on pursuing it for a little distance, another cascade scarcely inferior in picturesque attraction to Thomason Foss, will be found.
